+==============================================================================
+1. Overview					*lsp-overview*
+
+The Language Server Protocol (LSP) plugin implements a LSP client for Vim9.
+Refer to the following pages for more information about LSP:
+
+    https://microsoft.github.io/language-server-protocol/
+    https://langserver.org/
+
+This plugin needs Vim version 9.0 and after. You will need a programming
+language specific server in your system to use this plugin. Refer to the above
+pages for a list of available language servers for the various programming
+languages.
+
+The Github repository for this plugin is available at:
+
+      http://github.com/yegappan/lsp
+
+==============================================================================
+2. Installation					*lsp-installation*
+
+You can install this plugin directly from github using the following steps:
+
+    $ mkdir -p $HOME/.vim/pack/downloads/opt
+    $ cd $HOME/.vim/pack/downloads/opt
+    $ git clone https://github.com/yegappan/lsp
+    $ vim -u NONE -c "helptags $HOME/.vim/pack/downloads/opt/lsp/doc" -c q
+
+or you can use any one of the Vim plugin managers (dein.vim, pathogen, vam,
+vim-plug, volt, Vundle, etc.) to install and manage this plugin.
+
+To uninstall the LSP plugin, either use the uninstall command provided by the
+plugin manager or manually remove the $HOME/.vim/pack/downloads/lsp directory.

+==============================================================================
+4. Configuration				*lsp-configuration*
+					*LspAddServer()* *g:LspAddServer()*
+
+To use the plugin features with a particular file type(s), you need to first
+register a language server for that file type(s).
+
+To register one or more language servers, use the LspAddServer() function with
+a list of lanaguge server details in the .vimrc file.
+
+To register a language server, add the following lines to your .vimrc file
+(use only the language servers that you need from the below list).
+If you used [vim-plug](https://github.com/junegunn/vim-plug) to install the
+LSP plugin, the steps are described later in this section: >
+
+   vim9script
+   var lspServers = [
+		     {
+			 name: 'typescriptls',
+			 filetype: ['javascript', 'typescript'],
+			 path: '/usr/local/bin/typescript-language-server',
+			 args: ['--stdio']
+		      },
+		     {
+			 name: 'pythonls',
+			 filetype: 'python',
+			 path: '/usr/local/bin/pyls',
+			 args: ['--check-parent-process', '-v']
+		      }
+		   ]
+   LspAddServer(lspServers)
+<
+Depending on the location of the typescript and python pyls language servers
+installed in your system, update the "path" in the above snippet
+appropriately.
+
+Another example, for adding the language servers for the C, C++, Golang, Rust,
+Shell script, Vim script and PHP file types: >
+
+   vim9script
+   var lspServers = [
+		     {
+			name: 'clangd',
+		        filetype: ['c', 'cpp'],
+		        path: '/usr/local/bin/clangd',
+		        args: ['--background-index']
+		     },
+                     {
+			name: 'golang',
+                        filetype: ['go', 'gomod', 'gohtmltmpl', 'gotexttmpl'],
+                        path: '/path/to/.go/bin/gopls',
+                        args: [],
+                        syncInit: true,
+                      },
+                     {
+			name: 'rustls',
+                        filetype: ['rust'],
+                        path: '/path/to/.cargo/bin/rust-analyzer',
+                        args: [],
+                        syncInit: true,
+                      },
+		     {
+			name: 'bashls',
+			filetype: 'sh',
+			path: '/usr/local/bin/bash-language-server',
+			args: ['start']
+		     },
+		     {
+			name: 'vimls',
+			filetype: ['vim'],
+			path: '/usr/local/bin/vim-language-server',
+			args: ['--stdio']
+		     },
+		     {
+			name: 'phpls',
+		        filetype: ['php'],
+		        path': '/usr/local/bin/intelephense',
+		        args: ['--stdio'],
+		        syncInit: true,
+		        initializationOptions: {
+		        licenceKey: 'xxxxxxxxxxxxxxx'
+		        }
+		      }
+		   ]
+   LspAddServer(lspServers)
+<
+To add a language server, the following information is needed:
+
+						*lsp-cfg-name*
+	name		(Optional) name of the language server.  Can by any
+			string.  Used in LSP messages and log files.
+						*lsp-cfg-path*
+	path		complete path to the language server executable
+			(without any arguments).
+						*lsp-cfg-args*
+	args		a |List| of command-line arguments passed to the
+			language server.  Each space separated language server
+			command-line argument is a separate List item.
+						*lsp-cfg-filetype*
+	filetype	One or more file types supported by the language
+			server.  This can be a |String| or a |List|. To
+			specify multiple file types, use a List.
+					*lsp-cfg-initializationOptions*
+	initializationOptions
+			(Optional) for lsp servers (e.g. intelephense) some
+			additional initialization options may be required
+			or useful for initialization. Those can be provided in
+			this dictionary and if present will be transmitted to
+			the lsp server.
+						*lsp-cfg-workspaceConfig*
+	workspaceConfig (Optional) a json encodable value that will be sent to
+			the language server after initialization as the
+			"settings" in a "workspace/didChangeConfiguration"
+			notification.  Refer to the language server
+			documentation for the values that will be accepted in
+			this notification.  This configuration is also used to
+			respond to the "workspace/configuration" request
+			message from the language server.
+						*lsp-cfg-rootSearch*
+	rootSearch	(Optional) a List of file and directory names used to
+			locate the root path or uri of the workspace.  The
+			directory names in "rootSearch" must end in "/" or
+			"\".  Each file and directory name in "rootSearch" is
+			searched upwards in all the parent directories.  If
+			multiple directories are found, then the directory
+			closest to the directory of the current buffer is used
+			as the workspace root.
+
+			If this parameter is not specified or the files are
+			not found, then the current working directory is used
+			as the workspace root for decendent files, for any
+			other files the parent directory of the file is used.
+
+						*lsp-cfg-runIfSearch*
+	runIfSearch	(Optional) a List of file and directory names used to
+			determinate if a server should run or not. The
+			directory names in "runIfSearch" must end in "/" or
+			"\".  Each file and directory name in "runIfSearch" is
+			searched upwards in all the parent directories.
+			Exactly like |lsp-cfg-rootSearch|.
+
+			If a file or directory is found then the server will
+			be started, otherwise it will not.
+
+			If this parameter is not specified or is an empty
+			list, then the server will be started unless
+			|lsp-cfg-runUnlessSearch| prevents it.
+
+						*lsp-cfg-runUnlessSearch*
+	runUnlessSearch	(Optional) Opposite of |lsp-cfg-runIfSearch|.
+
+Additionally the following configurations can be made:
+
+					*lsp-cfg-customNotificationHandlers*
+	customNotificationHandlers
+			(Optional) some lsp servers (e.g.
+			typescript-language-server) will send additional
+			notifications which you might want to silence or
+			handle.  The provided notification handlers will be
+			called with a reference to the "lspserver" and the
+			"reply". >
+
+		vim9script
+		g:LspAddServer([{
+			filetype: ['javascript', 'typescript'],
+			path: '/usr/local/bin/typescript-language-server',
+			args: ['--stdio'],
+			customNotificationHandlers: {
+				'$/typescriptVersion': (lspserver, reply) => {
+					echom printf("TypeScript Version = %s",
+						reply.params.version)
+				}
+			}
+		}])
+<
+					*lsp-cfg-customRequestHandlers*
+	customRequestHandlers
+			(Optional) some lsp servers will send additional
+			request replies which you might want to silence or
+			handle.  The provided request handlers will be called
+			with a reference to the "lspserver" and the "request".
+
+	features				*lsp-cfg-features*
+			(Optional) toggle which features should be enabled for
+			a given language server. See |lsp-multiple-servers|
+			and |lsp-features| for more information.
+
+	forceOffsetEncoding			*lsp-cfg-forceOffsetEncoding*
+			(Optional) a |String| value that forces the use of a
+			specific offset encoding in LSP messages.  If this
+			option is not specified, then the UTF offset encoding
+			is negotiated with the server during initialization.
+			Supported values are 'utf-8' or 'utf-16' or 'utf-32'.
+			The Vim native offset encoding is 'utf-32'.  For the
+			'utf-8' and 'utf-16' encodings, the offsets need to be
+			encoded and decoded in every LSP message and will
+			incur some overhead.
+
+						*lsp-cfg-omnicompl*
+	omnicompl	(Optional) a boolean value that enables (true)
+			or disables (false) omni-completion for these file
+			types. By default this is set to "v:true".  This value
+			is applicable only if auto completion is disabled
+			(|lsp-opt-autoComplete|).
+
+						*lsp-cfg-processDiagHandler*
+	processDiagHandler
+			(Optional) A |Funcref| or |lambda| that takes a list
+			of language server diagnostics and returns a new list
+			of filtered, or otherwise changed diagnostics.  Can be
+			used to remove unwanted diagnostics, prefix the
+			diagnostics text, etc.  The following example will
+			remove all but errors and warnings: >
+
+		vim9script
+		g:LspAddServer([{
+			filetype: ['javascript', 'typescript'],
+			path: '/usr/local/bin/typescript-language-server',
+			args: ['--stdio'],
+			processDiagHandler: (diags: list<dict<any>>) => {
+				# Only include errors and warnings
+				return diags->filter((diag, ix) => {
+					return diag.severity <= 2
+				})
+			},
+		}])
+<
+			And this example will prefix the diagnostic message
+			with the string "TypeScript: ": >
+
+		vim9script
+		g:LspAddServer([{
+			filetype: ['javascript', 'typescript'],
+			path: '/usr/local/bin/typescript-language-server',
+			args: ['--stdio'],
+			processDiagHandler: (diags: list<dict<any>>) => {
+				return diags->map((diag, ix) => {
+					diag.message = $'TypeScript: {diag.message}'
+					return diag
+				})
+			},
+		}])
+<
+						*lsp-cfg-syncInit*
+	syncInit        (Optional) for language servers (e.g. rust analyzer,
+			gopls, etc.) that take time to initialize and reply to
+			a "initialize" request message this should be set to
+			"true". If this is set to true, then a synchronous
+			call is used to initialize the language server,
+			otherwise the server is initialized asynchronously.
+			By default this is set to "false".
+
+						*lsp-cfg-debug*
+	debug		(Optional) log the messages printed by this language
+			server in stdout and stderr to a file.  Useful for
+			debugging a language server.  By default the
+			messages are not logged.  See |lsp-debug| for more
+			information.
+
+						*lsp-cfg-traceLevel*
+	traceLevel	(Optional) set the debug trace level for this language
+			server.  Supported values are: "off", "debug" and
+			"verbose".  By default this is seto "off".
+
+The language servers are added using the LspAddServer() function. This
+function accepts a list of language servers with the above information.
+
+If you used [vim-plug](https://github.com/junegunn/vim-plug) to install the
+LSP plugin, then you need to use the LspSetup User autocmd to initialize the
+language server and to set the language server options.  For example: >
+
+    vim9script
+
+    var lspOpts = {autoHighlightDiags: true}
+    autocmd User LspSetup LspOptionsSet(lspOpts)
+
+    var lspServers = [
+		     {
+		        name: 'clangd',
+		        filetype: ['c', 'cpp'],
+		        path: '/usr/local/bin/clangd',
+		        args: ['--background-index']
+		      }
+		   ]
+    autocmd User LspSetup LspAddServer(lspServers)
+<
+						*lsp-options* *LspOptionsSet()*
+						*g:LspOptionsSet()*
+
+Some of the LSP plugin features can be enabled or disabled by using the
+LspOptionsSet() function. This function accepts a dictionary argument with the
+following optional items:
+

+
+			This option only works for language servers that
+			expect the client to filter the completion items.
+
+			This option accepts one of the following values:
+			    case  - case sensitive matching (default).
+			    fuzzy - fuzzy match completion items.
+			    icase - ignore case when matching items.
+
+						*lsp-opt-completionTextEdit*

+5. Commands					*lsp-commands*
+
+A description of the various commands provided by this plugin is below.  You
+can map these commands to keys and make it easier to invoke them.
+
+						*:LspCodeAction*
+:LspCodeAction [query]	Apply the code action supplied by the language server
+			to the diagnostic in the current line. This works only
+			if there is a diagnostic message for the current line.
+			You can use the ":LspDiag current" command to display
+			the diagnostic for the current line.
+
+			When [query] is given the code action starting with
+			[query] will be applied. [query] can be a regexp
+			pattern, or a digit corresponding to the index of the
+			code actions in the created prompt.
+
+			When [query] is not given you will be prompted to
+			select one of the actions supplied by the language
+			server.
+
+						*:LspCodeLens*
+:LspCodeLens		Display a list of code lens commands available for the
+			current buffer and apply the selected code lens
+			command.
+
+						*:LspDiag-current*
+:LspDiag current	Displays the diagnostic message (if any) for the
+			current line.  If the option 'showDiagInPopup' is set
+			to true (default), then the message is displayed in
+			a popup window.  Otherwise the message is displayed in
+			the status message area.
+
+:LspDiag! current	Only display a diagnostic message if it's directly
+			under the cursor.  Otherwise works exactly like
+			":LspDiag current"
+
+			To show the current diagnotic under the cursor while
+			moving around the following autocmd can be used: >
+
+			    augroup LspCustom
+			      au!
+			      au CursorMoved * silent! LspDiag! current

+			for the current Vim session.
+			To always disable the highlighting, set the
+			autoHighlightDiags option to false.
+
+:LspDiag highlight enable			*:LspDiag-highlight-enable*
+			Enable highlighting lines with a diagnostic message
+			for the current Vim session.  Note that highlighting
+			lines with a diagnostic message is enabled by default.

+			for the current file.
+
+						*:LspDiag-next*
+:[count]LspDiag next	Go to the [count] diagnostic message after the current
+			cursor position.  If [count] is omitted, then 1 is
+			used.  If [count] exceeds the number of diagnostics
+			after the current position, then the last diagnostic
+			is selected.
+
+						*:LspDiag-prev*
+:[count]LspDiag prev	Go to the [count] diagnostic message before the
+			current cursor position.  If [count] is omitted, then
+			1 is used.  If [count] exceeds the number of
+			diagnostics before the current position, then first
+			last diagnostic is selected.
+
+						*:LspDiag-show*
+:LspDiag show		Creates a new location list with the diagnostics
+			messages (if any) from the language server for the
+			current file and opens the location list window. You
+			can use the Vim location list commands to browse the
+			list.
+
+						*:LspDocumentSymbol*
+:LspDocumentSymbol	Display the symbols in the current file in a popup
+			menu.  When a symbol is selected in the popup menu by
+			pressing <Enter> or <Space>, jump to the location of
+			the symbol.
+
+			The <Up>, <Down>, <Tab>, <S-Tab>, <C-N>, <C-P>,
+			<ScrollWheelUp>, ScrollWheelDown> keys can be used to
+			scroll popup menu one item at a time. <PageUp> and
+			<PageDown> can be used to scroll a page of popup
+			window, while <C-F> and <C-B> can be used to scroll a
+			page of underlying window.  The <Esc> or <Ctrl-C> keys
+			can be used to cancel the popup menu.
+
+			If one or more keyword characters are typed, then only
+			the symbols containing the keyword characters are
+			displayed in the popup menu.  Fuzzy searching is used
+			to get the list of matching symbols.  The <BS> key can
+			be used to erase the last typed character.  The <C-U>
+			key can be used to erase all the characters.
+
+			When scrolling through the symbols in the popup menu,
+			the corresponding range of lines is highlighted.
+
+						*:LspFold*
+:LspFold		Create folds for the current buffer.

+
+						*:LspGotoDefinition*
+:[count]LspGotoDefinition
+			Jumps to the [count] definition of the symbol under
+			the cursor.  If there are multiple matches and [count]
+			isn't specified, then a location list will be created
+			with the list of locations.
+
+			If there is only one location, or [count] is provided
+			then the following will apply:
+
+			If the file is already present in a window, then jumps
+			to that window.  Otherwise, opens the file in a new
+			window.  If the current buffer is modified and
+			'hidden' is not set or if the current buffer is a
+			special buffer, then a new window is opened.  If the
+			jump is successful, then the current cursor location
+			is pushed onto the tag stack.  The |CTRL-T| command
+			can be used to go back up the tag stack.  Also the
+			|``| mark is set to the position before the jump.
+
+			This command supports |:command-modifiers|.  You can
+			use the modifiers to specify whether a new window or
+			a new tab page is used and where the window is opened.
+			Example(s): >
+
+			    # Open a horizontally split window
+			    :topleft LspGotoDefinition
+			    # Open a vertically split window

+						*:LspOutline*
+:[count]LspOutline	Opens a vertically split window with the list of
+			symbols defined in the current file. The current
+			symbol is highlighted. The symbols are grouped by
+			their type. You can select a symbol and press <Enter>
+			to jump to the position of the symbol. As you move the
+			cursor in a file, the current symbol is automatically
+			highlighted in the outline window. If you open a new
+			file, the outline window is automatically updated with
+			the symbols in the new file.  Folds are created in the
+			outline window for the various group of symbols.
+
+			You can use |lsp-opt-outlineOnRight| and
+			|lsp-opt-outlineWinSize| to customize the placement
+			and size of the window.
+
+			This command also supports |:command-modifiers|.  You
+			can use the modifiers specify the position of the
+			window.  Note that the default is ":vert :topleft" or
+			":vert :botright" depending on

+
+			This command also supports providing a [count] to
+			specify the size of the window.  Note that this
+			overrides the values defined in
+			|lsp-opt-outlineWinSize|.
+			Example: >
+
+			    # Open the outline window just above the current
+			    # window
+			    :aboveleft LspOutline
+
+			    # Open the outline window just next to the current
+			    # window, this is different from the default, when
+			    # you have multiple splits already
+			    :vert aboveleft LspOutline
+
+			    # Same as above, but with a width of 50
+			    :vert aboveleft 50LspOutline
+<
+						*:LspPeekDeclaration*

+:[count]LspPeekDefinition
+			Displays the line where the symbol under the cursor is
+			defined in a popup window. The symbol is highlighted
+			in the popup window. Moving the cursor or pressing
+			<Esc> will close the popup window.
+			When more than one symbol is found all of them will be
+			shown.  The corresponding file for the symbol is
+			displayed in another popup window.  As the selection
+			in the symbol popup menu changes, the file in the

+			status and the path to the language server executable.
+			The language server information for each buffer is
+			also shown.
+
+						*:LspShowReferences*
+:LspShowReferences	Creates a new location list with the list of locations
+			where the symbol under the cursor is referenced and

+			this, you can set the showSignature option to false in
+			your .vimrc file: >
+
+			LspOptionsSet({'showSignature': false})
+<
+			Default is true.
+
+			You can get the function signature echoed in cmdline
+			rather than displayed in popup if you use >
+
+			LspOptionsSet({'echoSignature': true})
+<
+			Default is false.
+
+						*:LspSubTypeHierarchy*
+:LspSubTypeHierarchy	Show the sub type hierarchy for the symbol under the
+			cursor in a popup window.  The file containing the

+			file popup window is updated to show the location
+			where the type is defined.  You can jump to the
+			location where a type is defined by selecting the
+			entry in the popup menu.
+
+			Note that the type hierarchy support is based on the
+			protocol supported by clangd.  This is different from
+			the one specified in the 3.17 of the LSP standard.
+
+						*:LspSwitchSourceHeader*
+:LspSwitchSourceHeader	Switch between source and header files. This is a
+			Clangd specific extension and only works with C/C++

+			If <sym> is not supplied, then you will be prompted to
+			enter the symbol name (the keyword under the cursor is
+			used as the default).  If there is only one matching
+			symbol, then the cursor will be positioned at the
+			symbol location.  Otherwise a popup window is opened
+			with the list of matching symbols.  You can enter a
+			few characters to narrow down the list of matches. The
+			displayed symbol name can be erased by pressing
+			<Backspace> or <C-U> and a new symbol search pattern
+			can be entered.  You can close the popup menu by
+			pressing the escape key or by pressing CTRL-C.
+
+			In the popup menu, the following keys can be used:

+				<BS>       - Erase one character from the
+					     filter text
+				<C-H>      - idem
+				<C-U>      - Erase the filter text
+
+			Any other alphanumeric key will be used to narrow down
+			the list of names displayed in the popup menu. When
+			you type a filter string, then only the symbols fuzzy
+			matching the string are displayed in the popup menu.
+			You can enter a new search pattern to do a workspace
+			wide symbol search.
+
+			This command accepts |:command-modifiers| which can be
+			used to jump to a symbol in a horizontally or
+			vertically split window or a new tab page: >
+
+				:topleft LspSymbolSearch foo
+				:vert LspSymbolSearch bar

+6. Insert Mode Completion		    *lsp-ins-mode-completion*
+
+By default, when you are in insert mode, the LSP plugin will automatically
+display suggestions for the symbol under the cursor in an insert-completion
+popup menu. The keys specified in |popupmenu-keys| can be used to interact
+with this menu.
+
+To disable this auto-completion feature for all files, you can set the
+"autoComplete" option to false in your .vimrc file using the |LspOptionsSet()|
+function: >
+
+    call LspOptionsSet({'autoComplete': false})
+<
+By setting the "autoComplete" option to |v:false|, the LSP plugin will no
+longer automatically trigger completion suggestions in insert mode. Instead,
+it will use omni-completion (|compl-omni|) and set the 'omnifunc' option for
+buffers that have a registered language server. To manually trigger symbol
+completion in insert mode, you can press CTRL-X CTRL-O. This key combination
+will invoke completion using the suggestions provided by the language server.
+
+To enable omni-completion for all the buffers, set the "omniComplete" option
+to v:true.  To explicitly disable omni-completion for all the buffers, set the
+"omniComplete" option to v:false (default).
+
+In addition to the general auto-completion behavior discussed above, you
+have the option to enable or disable omni-completion for a specific language
+server when registering it for a particular filetype.
+
+To do this, you can set the 'omnicompl' item to |v:false| in the configuration
+when registering the language server for the desired filetype. If the
+'omnicompl' item is not specified, omni-completion is enabled by default.
+
+Here's an example of how to disable omni-completion for Python: >
+
+    vim9script
+    var lspServers = [
+		     {
+			filetype: 'python',
+			omnicompl: false,
+			path: '/usr/local/bin/pyls',
+			args: ['--check-parent-process', '-v']
+		     }
+		   ]
+<
+In this example, the language server for Python is registered using the
+|LspAddServer()| function, and the 'omnicompl' item is explicitly set to
+|v:false|. As a result, omni-completion will be disabled for Python files
+associated with this language server.
+
+Please note that if 'omnicompl' is not included in the configuration
+when registering the language server, omni-completion will be enabled by
+default.
+
+In insert-mode completion, the plugin sends a completion request message to
+the language server and obtains a list of potential completion matches based
+on the current cursor position. To achieve this, the plugin retrieves the
+keyword immediately preceding the cursor (refer to 'iskeyword' setting) and
+then filters the list of completion items received from the language server
+based on this keyword.  The resulting filtered list is displayed as the
+completion menu.
+
+It's worth noting that different language servers handle completion filtering
+in distinct ways. Some servers perform the filtering directly on the
+server-side, while others delegate this task to the client-side, which is the
+plugin in this context.
+
+By default, the plugin uses a case-sensitive comparison method to filter the
+returned completion items. However, you have the flexibility to customize this
+behavior by modifying the "completionMatcher" option. This option allows you
+to switch between case-insensitive or fuzzy comparison methods as per your
+preference and requirements for completion matching.
+
+In addition to automatic completion and omni completion, there is a
+possibility to utilize external completion engines with the LSP client. This
+can be achieved by repurposing the |g:LspOmniFunc| function. The external
+completion engine adapter needs to invoke this function twice, following the
+approach outlined in the |complete-functions| documentation.
+
+The process works as follows:
+
+1. First Invocation: The external completion engine adapter calls
+   |g:LspOmniFunc| to initiate a request to the LSP server for completion
+   candidates.
+2. After the first invocation, a request is sent to the LSP server to find
+   completion candidates.
+3. Second Invocation: The external completion engine adapter calls
+   |g:LspOmniFunc| again to retrieve the matches returned by the LSP server.
+4. If the LSP server is not ready to reply immediately, |g:LspOmniFunc| waits
+   for up to 2 seconds.
+5. However, this wait could block the caller from performing other tasks,
+   which might be a concern for asynchronous completion engines.
+6. To address this issue, the adapter can use the |g:LspOmniCompletePending|
+   function, which allows for a non-blocking check. It returns true
+   immediately if the language server is not ready to respond yet.
+7. To proceed with the second invocation of g:LspOmniFunc, it is crucial to
+   ensure that |g:LspOmniCompletePending| returns false, indicating that the
+   language server is now ready to provide the completion matches.
+
+==============================================================================
+7. Diagnostics						*lsp-diagnostics*
+
+The LSP plugin offers a feature to highlight syntax errors, warnings, and
+static analysis warnings in a source file by placing signs in the sign column.
+These signs serve as visual indicators of the diagnostics reported by the
+language server.
+
+To interact with these diagnostics, you can use various commands provided by
+the LSP plugin:
+
+1. ":LspDiag show": This command displays all the diagnostic messages for the
+   current file in a location-list window.  The location-list window allows
+   you to view a list of all the diagnostic messages, along with their
+   corresponding line numbers and descriptions.
+2. ":LspDiag first": Use this command to jump directly to the line containing
+   the first diagnostic message.  It helps you quickly navigate to the
+   location of the initial issue detected by the language server.
+3. ":LspDiag next": With this command, you can navigate to the next nearest
+   line with a diagnostic message.  It helps you step through the list of
+   diagnostics one by one.
+4. ":LspDiag prev": Conversely, this command allows you to jump to the
+   previous nearest line with a diagnostic message.  It is useful for
+   reviewing diagnostics in reverse order.
+5. ":LspDiag here": If you want to focus solely on the diagnostic message for
+   the current line, you can use this command to jump directly to it.
+6. ":LspDiag current": This command displays the entire diagnostic message
+   from the language server for the current line.  It provides detailed
+   information about the specific issue and its description.
+
+By using these commands, you can efficiently navigate and inspect the
+diagnostics reported by the language server, making it easier to identify and
+address syntax errors, warnings, or static analysis issues in your code.
+
+By default, the LSP plugin marks lines with diagnostic messages by placing a
+sign on them and highlighting the range of text associated with the
+diagnostic.  However, you have the option to customize this behavior by
+adjusting certain configuration settings:
+
+1. Disabling Automatic Sign Placement: If you wish to prevent the automatic
+   placement of signs on lines with diagnostic messages, you can achieve this
+   by setting the "showDiagWithSign" option to |v:false|.  By default, this
+   option is set to |v:true|, meaning that signs are automatically placed on
+   lines with diagnostics.
+2. Disabling Diagnostic Text Highlighting: If you prefer not to have the
+   diagnostic text highlighted, you can do so by setting the
+   "highlightDiagInline" option to |v:false|.  By default, this option is set
+   to |v:true|, resulting in the highlighting of the text range associated
+   with each diagnostic.
+3. Highlight Group for Line with Diagnostics: The LSP plugin uses the
+   "LspDiagLine" highlight group to highlight lines containing diagnostics.
+   By default, this highlight group is not set, allowing you to define your
+   own highlighting style for lines with diagnostics if desired.
+
+In addition to the default display of the diagnostic messages with signs and
+text highlighting, the LSP plugin offers the option to present the diagnostic
+message as virtual text, located near the relevant location of the
+diagnostics.  To enable this feature, you can set the
+"showDiagWithVirtualText" option to |v:true|.  However, please note that this
+functionality requires Vim version 9.0.1157 or later.  By default, this option
+is set to |v:false|, meaning that virtual text display is not activated.
+
+The position of the virtual text can be controlled using the
+"diagVirtualTextAlign" option, which determines its alignment relative to the
+affected line.  By default, this option is set to 'above', which places the
+virtual text above the line with the diagnostic message.  The other supported
+values for "diagVirtualTextAlign" are 'below', which positions the virtual
+text below the affected line, and 'after', which displays the virtual text
+immediately after the text on the affected line.
+
+The wrapping of the virtual text can be controlled using the
+"diagVirtualTextWrap" option. By default, this option is set to 'default',
+which will 'truncate' virtual text placed 'above' or 'below' the affected
+line, and 'wrap' text placed 'after' the affected line. Setting the value to
+'wrap' or 'truncate' will force the specified behavior for the current
+value of "diagVirtualTextAlign". If 'truncate' is used while
+"diagVirtualTextAlign" is set to 'after', and a diagnostic message has already
+been truncated for the affected line, then further diagnostics will be placed
+below the affected line.
+
+The LSP plugin offers convenient ways to highlight diagnostic messages, making
+it easier to spot errors, warnings, hints, or informational notices within
+your code.  By default, the plugin automatically highlights the range of text
+associated with each diagnostic message when the "highlightDiagInline" option
+is set to |v:true.|
+
+The highlighting is done using different highlight groups based on the type of
+diagnostic message:
+
+    "LspDiagInlineError" for error messages.
+    "LspDiagInlineHint" for hints.
+    "LspDiagInlineInfo" for informational messages.
+    "LspDiagInlineWarning" for warning messages.
+
+If you wish to temporarily disable the automatic diagnostic highlighting for
+the current Vim session, you can achieve this using the ":LspDiag highlight
+disable" command.  When you want to re-enable the highlighting, you can use
+the ":LspDiag highlight enable" command.
+
+To permanently disable the automatic highlighting of diagnostics, you can set
+the "autoHighlightDiags" option to |v:false| in your .vimrc file.  This
+configuration can be achieved using the |LspOptionsSet()| function: >
+
+    call LspOptionsSet({'autoHighlightDiags': v:false})
+<
+By default, the "autoHighlightDiags" option is set to |v:true|, ensuring that
+diagnostic messages are automatically highlighted during your coding sessions.
+
+The lsp#lsp#ErrorCount() function returns the count of diagnostic messages in
+the current buffer, categorized by their types.  When called, this function
+returns a Dictionary containing four keys: "Info," "Hint," "Warn," and
+"Error." Each key corresponds to a specific diagnostic type, and its
+associated value is the number of diagnostic messages of that particular type
+found in the buffer.  With the information gathered using this function, you
+can easily display the number of diagnostics in the current buffer in your
+'statusline'.
+
+For some diagnostic errors/warnings, the language server may provide an
+automatic fix.  To apply this fix, you can use the |:LspCodeAction| command.
+This command applies the action provided by the language server (if any) for
+the current line.
+
+The ":LspDiag show" command creates a new location list with the current list
+of diagnostics for the current buffer.  To automatically refresh the location
+list with the latest diagnostics received from the language server, you can
+set the "autoPopulateDiags" option to |v:true|.  By default this option is set
+to |v:false|.  When new diagnostics are received for a buffer, if a location
+list with the diagnostics is already present, then it is refreshed with the
+new diagnostics.
+
+In GUI Vim or terminal Vim with the 'balloonevalterm' option enabled, a
+helpful feature allows you to view diagnostic messages in a popup balloon when
+you hover the mouse over the affected range of text.  This provides a
+convenient way to quickly access diagnostic information without the need to
+execute additional commands or navigate through the location list.
+
+By default, the LSP plugin is configured to display diagnostic messages in the
+popup balloon, enhancing the user experience and providing visual feedback as
+you interact with your code.  This default behavior is governed by the
+"showDiagInBalloon" option, which is set to |v:true| by default.
+
+However, if you prefer not to see the diagnostic messages in the popup
+balloons and prefer to rely solely on other methods, you have the flexibility
+to customize this behavior.  By setting the "showDiagInBalloon" option to
+|v:false|, you can disable the display of diagnostic messages in the popup
+balloons.  This can be useful if you find the balloons intrusive or if you
+prefer to view diagnostics through other means, such as the location list or
+the status line.
+
+To display the diagnostic message for the current line in the status area, you
+can set the "showDiagOnStatusLine" option to |v:true|.  By default, this
+option is set to |v:false|.
+
+By default, the ":LspDiag current" command displays the diagnostic message for
+the current line in a popup window.  To display the message in the status
+message area instead, you can set the 'showDiagInPopup' option to |v:false|.
+By default this is set to |v:true|.
+
+The lsp#diag#GetDiagsForBuf() function can be used to get all the LSP
+diagnostics in a buffer.  This function optionally accepts a buffer number.
+If the buffer number argument is not specified, then the current buffer is
+used.  This function returns a |List| of diagnostics sorted by their line and
+column number.  Each diagnostic is a |Dict| returned by the language server.
+
+==============================================================================
+8. Tag Function					*lsp-tagfunc*
+
+The |:LspGotoDefinition| command can be used jump to the location where a
+symbol is defined.  To jump to the symbol definition using the Vim
+|tag-commands|, you can set the 'tagfunc' option to the 'lsp#lsp#TagFunc'
+function: >
+
+	setlocal tagfunc=lsp#lsp#TagFunc
+<
+After setting the above option, you can use |Ctrl-]| and other tag related
+commands to jump to the symbol definition.
+
+Note that most of the language servers return only one symbol location even if
+the symbol is defined in multiple places in the code.
+
+==============================================================================
+9. Code Formatting				*lsp-format*
+
+The |:LspFormat| command can be used to format either the entire file or a
+selected range of lines using the language server.  The 'shiftwidth' and
+'expandtab' values set for the current buffer are used when format is applied.
+
+To format code using the 'gq' command, you can set the 'formatexpr' option: >
+
+    setlocal formatexpr=lsp#lsp#FormatExpr()
+<
+==============================================================================
+10. Call Hierarchy				*lsp-call-hierarchy*
+
+The |:LspIncomingCalls| and the |:LspOutoingCalls| commands can be used to
+display the call hierarchy of a symbol.  For example, the functions calling a
+function or the functions called by a function.  These two commands open a
+window containing the call hierarchy tree.  You can use the Vim motion
+commands to browse the call hierarchy.
+
+In the call hierarchy tree window, the following keys are supported:
+
+<Enter>				Jump to the location of the symbol under the
+				cursor.
+-				Expand and show the symbols calling or called
+				by the symbol under the cursor.
++				Close the call hierarchy for the symbol under
+				the cursor.
+
+You can display either the incoming call hierarchy or the outgoing call
+hierarchy in this window.  You cannot display both at the same time.
+
+In the call hierarchy tree window, the following commands are supported:
+
+						*:LspCallHierarchyRefresh*
+:LspCallHierarchyRefresh	Query the language server again for the top
+				level symbol and refresh the call hierarchy
+				tree.
+						*:LspCallHierarchyIncoming*
+:LspCallHierarchyIncoming	Display the incoming call hierarchy for the
+				top level symbol.  If the window is currently
+				displaying the outgoing calls, then it is
+				refreshed to display the incoming calls.
+						*:LspCallHierarchyOutgoing*
+:LspCallHierarchyOutgoing	Display the outgoing call hierarchy for the
+				top level symbol.  If the window is currently
+				displaying the incoming calls, then it is
+				refreshed to display the outgoing calls.
+
+==============================================================================
+11. Autocommands				*lsp-autocmds*
+
+						*LspSetup*
+LspSetup			A |User| autocommand fired when the LSP plugin
+				is loaded.  Can be used to add language
+				servers using the |LspAddServer()| function
+				and to set plugin options using the
+				|LspOptionsSet()| function.
+
+						*LspAttached*
+LspAttached			A |User| autocommand fired when the LSP client
+				attaches to a buffer. Can be used to configure
+				buffer-local mappings or options.
+
+						*LspDiagsUpdated*
+LspDiagsUpdated			A |User| autocommand invoked when new
+				diagnostics are received from the language
+				server.  This is invoked after the LSP client
+				has processed the diagnostics.  The function
+				lsp#diag#GetDiagsForBuf() can be used to get
+				all the diagnostics for a buffer.
+
+==============================================================================
+12. Highlight Groups				*lsp-highlight-groups*
+
+The following highlight groups are used by the LSP plugin.  You can define
+these highlight groups in your .vimrc file before sourcing this plugin to
+override them.
+
+*LspDiagInlineError*		Used to highlight inline error diagnostics.
+				By default, linked to the "SpellBad" highlight
+				group.
+*LspDiagInlineHint*		Used to highlight inline hint diagnostics.
+				By default, linked to the "SpellLocal"
+				highlight group.
+*LspDiagInlineInfo*		Used to highlight inline info diagnostics.
+				By default, linked to the "SpellRare"
+				highlight group.
+*LspDiagInlineWarning*		Used to highlight inline warning diagnostics.
+				By default, linked to the "SpellCap" highlight
+				group.
+*LspDiagLine*			Used to highlight a line with one or more
+				diagnostics.  By default linked to "NONE"
+				(cleared).  You can link this to a highlight
+				group to highlight the line.
+*LspDiagSignErrorText*		Used to highlight the sign text for error
+				diags.  By default linked to 'ErrorMsg'.
+*LspDiagSignHintText*		Used to highlight the sign text for hint
+				diags.  By default linked to 'Question'.
+*LspDiagSignInfoText*		Used to highlight the sign text for info
+				diags.  By default linked to 'Pmenu'.
+*LspDiagSignWarningText*	Used to highlight the sign text for warning
+				diags.  By default linked to 'Search'.
+*LspDiagVirtualText*		Used to highlight diagnostic virtual text.
+				By default, linked to the "LineNr" highlight
+				group.
+*LspDiagVirtualTextError*	Used to highlight virtual text for error diags.
+				By default, linked to the "SpellBad" highlight
+				group.
+*LspDiagVirtualTextHint*	Used to highlight virtual text for hint
+				diags.  By default, linked to the "SpellLocal"
+				highlight group.
+*LspDiagVirtualTextInfo*	Used to highlight virtual text for info
+				diags.  By default, linked to the "SpellRare"
+				highlight group.
+*LspDiagVirtualTextWarning*	Used to highlight virtual text for warning
+				diags.  By default, linked to the "SpellCap"
+				highlight group.
+*LspInlayHintsParam*		Used to highlight inlay hints of kind
+				"parameter".  By default, linked to the
+				"Label" highlight group.
+*LspInlayHintsType*		Used to highlight inlay hints of kind "type".
+				By default, linked to the "Conceal" highlight
+				group.
+*LspSigActiveParameter*		Used to highlight the active signature
+				parameter.  By default, linked to the "LineNr"
+				highlight group.
+*LspSymbolName*			Used to highlight the symbol name when using
+				the |:LspDocumentSymbol| command.  By default,
+				linked to the "Search" highlight group.
+*LspSymbolRange*		Used to highlight the range of lines
+				containing a symbol when using the
+				|:LspDocumentSymbol| command.  By default,
+				linked to the "Visual" highlight group.
+
+For example, to override the highlight used for diagnostics virtual text, you
+can use the following: >
+
+    highlight LspDiagVirtualText ctermfg=Cyan guifg=Blue
+<
+or >
+
+    highlight link LspDiagLine DiffAdd
+    highlight link LspDiagVirtualText WarningMsg
+<
+==============================================================================
+13. Debugging					*lsp-debug*
+
+To debug this plugin, you can log the language server protocol messages sent
+and received by the plugin from the language server.  The following command
+enables the logging of the messages from the language server for the current
+buffer: >
+
+    :LspServer debug on
+<
+This command also clears the log files.  The following command disables the
+logging of the messages from the language server for the current buffer: >
+
+    :LspServer debug off
+<
+By default, the messages are not logged.  Another method to enable the debug
+is to set the "debug" field to true when adding a language server
+using |LspAddServer()|.
+
+The messages printed by the language server in the stdout are logged to the
+lsp-<server-name>.log file and the messages printed in the stderr are logged
+to the lsp-<server-name>.err file.  On a Unix-like system, these files are
+created in the /tmp directory.  On MS-Windows, these files are created in the
+%TEMP% directory.
+
+The following command opens the file containing the messages printed by the
+language server in the stdout: >
+
+    :LspServer debug messages
+<
+The following command opens the file containing the messages printed by the
+language server in the stderr: >
+
+    :LspServer debug errors
+<
+To debug language server initialization problems, after enabling the above
+server debug, you can restart the server for the file type in the current
+buffer using the following command: >
+
+    :LspServer restart
+<
+The language servers typically support command line options to enable debug
+messages and to increase the verbosity of the messages.  You can refer to the
+language server documentation for information about this.  You can include
+these options when registering the language server with this plugin.
+
+If a language server supports the "$/logTrace" LSP notification, then you can
+use the :LspServerTrace command to set the server trace value: >
+
+    :LspServer trace { off | messages | verbose }
+<
+==============================================================================
+14. Custom Command Handlers			*lsp-custom-commands*
+
+When applying a code action, the language server may issue a non-standard
+command.  For example, the Java language server uses non-standard commands
+(e.g. java.apply.workspaceEdit).  To handle these commands, you can register a
+callback function for each command using the LspRegisterCmdHandler() function.
+For example: >
+
+    vim9script
+    import autoload "lsp/textedit.vim"
+
+    def WorkspaceEdit(cmd: dict<any>)
+      for editAct in cmd.arguments
+	  textedit.ApplyWorkspaceEdit(editAct)
+      endfor
+    enddef
+    g:LspRegisterCmdHandler('java.apply.workspaceEdit', WorkspaceEdit)
+<
+Place the above code in a file named lsp_java/plugin/lsp_java.vim and load
+this plugin.
+
+The callback function should accept a Dict argument.  The Dict argument
+contains the LSP Command interface fields.  Refer to the LSP specification for
+more information about the "Command" interface.
+
+==============================================================================
+15. Custom LSP Completion Kinds			*lsp-custom-kinds*
+
+When a completion popup is triggered, the LSP client will use a default kind
+list to show in the completion "kind" section, to customize it, you need to
+use the option |lsp-opt-customCompletionKinds| and set all custom kinds in the
+option |lsp-opt-completionKinds| . There is a table with all default LSP
+kinds:
+
+ Kind Name              | Value
+------------------------|--------------------
+ Text                   | t
+ Method                 | m
+ Function               | f
+ Constructor            | C
+ Field                  | F
+ Variable               | v
+ Class                  | c
+ Interface              | i
+ Module                 | M
+ Property               | p
+ Unit                   | u
+ Value                  | V
+ Enum                   | e
+ Keyword                | k
+ Snippet                | S
+ Color                  | C
+ File                   | f
+ Reference              | r
+ Folder                 | F
+ EnumMember             | E
+ Constant               | d
+ Struct                 | s
+ Event                  | E
+ Operator               | o
+ TypeParameter          | T
+ Buffer                 | B
+
+For example, if you want to change the "Method" kind to the kind "method()": >
+
+	vim9script
+
+	g:LspOptionsSet({
+		customCompletionKinds: true,
+		completionKinds: {
+			"Method": "method()"
+		}
+	})
+<
+In the completion popup, will show something like this: >
+
+	var file = new File()
+
+	file.cre
+		| create                method() |
+		| createIfNotExists     method() |
+		| ...				 |
+<
+==============================================================================
+16. Multiple Language Servers for a buffer	*lsp-multiple-servers*
+
+It's possible to run multiple language servers for a given buffer.
+
+By default the language server defined first will be used for as much as it
+supports, then the next and so on. With the exception that diagnostics from
+all running language servers will be combined.
+
+This means that you can define a language server that only supports a subset
+of features at first and then define the general purpose language server after
+it:
+>
+	vim9script
+
+	g:LspAddServer([
+		# This language server reports that it only supports
+		# textDocument/documentFormatting, so it will be used
+		# for :LspFormat but nothing else.
+		{
+			filetype: ['html'],
+			path: 'html-pretty-lsp',
+			args: ['--stdio']
+		},
+		# This language server also supports
+		# textDocument/documentFormatting, but since it's been
+		# defined later, the one above will be used instead.
+		# However this server also supports
+		# textDocument/definition, textDocument/declaration,
+		# etc, so it will be used for :LspGotoDefinition,
+		# :LspGotoDeclaration, etc
+		{
+			filetype: ['html'],
+			path: 'html-language-server',
+			args: ['--stdio']
+		}
+	])
+<
+As shown in the example above the order of when the language servers are being
+defined is taken into account for a given method.  However sometimes the
+language server that you want to use for formatting also reports that it
+supports other features. In such a case you can do one of two things:
+
+1. change the order of language servers, and specify that a given language
+server should be used for a given method.
+
+2. set the unwanted features to |false| in the features |Dictionary| >
+
+	features: { 'codeAction': false }
+<
+For example, if you want to use the efm-langserver for formatting, but the
+typescript-language-server for everything else: >
+
+	vim9script
+
+	g:LspAddServer([
+		# this language server will be used by default, as it's defined

+Another way is to disable the unwanted features: for example if you don't want
+diagnostics from the typescript-language-server, but want to use it for
+everything else: >
+
+	vim9script
+
+	g:LspAddServer([
+		{
+			filetype: ['javascript', 'typescript'],
+			path: '/usr/local/bin/typescript-language-server',
