Problem: luals returns stricter diagnostics with bundled luarc.json Solution: Improve some function and type annotations: * use recognized uv.* types * disable diagnostic for global `vim` in shared.lua * docs: don't start comment lines with taglink (otherwise LuaLS will interpret it as a type) * add type alias for lpeg pattern * fix return annotation for `vim.secure.trust` * rename local Range object in vim.version (shadows `Range` in vim.treesitter) * fix some "missing fields" warnings * add missing required fields for test functions in eval.lua * rename lsp meta files for consistency

--- Configure diagnostic options globally or for a specific diagnostic

--- Configuration can be specified globally, per-namespace, or ephemerally
|
|
--- (i.e. only for a single call to |vim.diagnostic.set()| or
|
|
--- |vim.diagnostic.show()|). Ephemeral configuration has highest priority,
|
|
--- followed by namespace configuration, and finally global configuration.
|
|
---
|
|
--- For example, if a user enables virtual text globally with
|
|
--- <pre>lua
|
|
--- vim.diagnostic.config({ virtual_text = true })
|
|
--- </pre>
|
|
---
|
|
--- and a diagnostic producer sets diagnostics with
|
|
--- <pre>lua
|
|
--- vim.diagnostic.set(ns, 0, diagnostics, { virtual_text = false })
|
|
--- </pre>
|
|
---
|
|
--- then virtual text will not be enabled for those diagnostics.
|
|
---
|
|
---@note Each of the configuration options below accepts one of the following:
|
|
--- - `false`: Disable this feature
|
|
--- - `true`: Enable this feature, use default settings.
|
|
--- - `table`: Enable this feature with overrides. Use an empty table to use default values.
|
|
--- - `function`: Function with signature (namespace, bufnr) that returns any of the above.
|
|
---
|
|
---@param opts table|nil When omitted or "nil", retrieve the current configuration. Otherwise, a
|
|
--- configuration table with the following keys:
|
|
--- - underline: (default true) Use underline for diagnostics. Options:
|
|
--- * severity: Only underline diagnostics matching the given
|
|
--- severity |diagnostic-severity|
|
|
--- - virtual_text: (default true) Use virtual text for diagnostics. If multiple diagnostics
|
|
--- are set for a namespace, one prefix per diagnostic + the last diagnostic
|
|
--- message are shown.
|
|
--- Options:
|
|
--- * severity: Only show virtual text for diagnostics matching the given
|
|
--- severity |diagnostic-severity|
|
|
--- * source: (boolean or string) Include the diagnostic source in virtual
|
|
--- text. Use "if_many" to only show sources if there is more than
|
|
--- one diagnostic source in the buffer. Otherwise, any truthy value
|
|
--- means to always show the diagnostic source.
|
|
--- * spacing: (number) Amount of empty spaces inserted at the beginning
|
|
--- of the virtual text.
|
|
--- * prefix: (string or function) prepend diagnostic message with prefix.
|
|
--- If a function, it must have the signature (diagnostic) -> string,
|
|
--- where {diagnostic} is of type |diagnostic-structure|. This can be
|
|
--- used to render diagnostic symbols or error codes.
|
|
--- * suffix: (string or function) Append diagnostic message with suffix.
|
|
--- If a function, it must have the signature (diagnostic) ->
|
|
--- string, where {diagnostic} is of type |diagnostic-structure|.
|
|
--- This can be used to render an LSP diagnostic error code.
|
|
--- * format: (function) A function that takes a diagnostic as input and
|
|
--- returns a string. The return value is the text used to display
|
|
--- the diagnostic. Example:
|
|
--- <pre>lua
|
|
--- function(diagnostic)
|
|
--- if diagnostic.severity == vim.diagnostic.severity.ERROR then
|
|
--- return string.format("E: %s", diagnostic.message)
|
|
--- end
|
|
--- return diagnostic.message
|
|
--- end
|
|
--- </pre>
|
|
--- - signs: (default true) Use signs for diagnostics. Options:
|
|
--- * severity: Only show signs for diagnostics matching the given
|
|
--- severity |diagnostic-severity|
|
|
--- * priority: (number, default 10) Base priority to use for signs. When
|
|
--- {severity_sort} is used, the priority of a sign is adjusted based on
|
|
--- its severity. Otherwise, all signs use the same priority.
|
|
--- - float: Options for floating windows. See |vim.diagnostic.open_float()|.
|
|
--- - update_in_insert: (default false) Update diagnostics in Insert mode (if false,
|
|
--- diagnostics are updated on InsertLeave)
|
|
--- - severity_sort: (default false) Sort diagnostics by severity. This affects the order in
|
|
--- which signs and virtual text are displayed. When true, higher severities
|
|
--- are displayed before lower severities (e.g. ERROR is displayed before WARN).
|
|
--- Options:
|
|
--- * reverse: (boolean) Reverse sort order
|
|
---
|
|
---@param namespace integer|nil Update the options for the given namespace. When omitted, update the
|
|
--- global diagnostic options.

--- Defaults to the current buffer.

--- - namespace: (number) Limit diagnostics to the given namespace
|

--- - scope: (string, default "line") Show diagnostics from the whole buffer ("buffer"),

|
--- the current cursor line ("line"), or the current cursor position ("cursor").
|
|
--- Shorthand versions are also accepted ("c" for "cursor", "l" for "line", "b"
|
|
--- for "buffer").
|
|
--- - pos: (number or table) If {scope} is "line" or "cursor", use this position rather
|
|
--- than the cursor position. If a number, interpreted as a line number;
|
|
--- otherwise, a (row, col) tuple.
|
|
--- - severity_sort: (default false) Sort diagnostics by severity. Overrides the setting

--- from |vim.diagnostic.config()|.
|
|
--- - severity: See |diagnostic-severity|. Overrides the setting
|
|
--- from |vim.diagnostic.config()|.

|
|
--- table, it is interpreted as a [text, hl_group] tuple. Overrides the setting
|
|
--- from |vim.diagnostic.config()|.
|
|
--- - source: (boolean or string) Include the diagnostic source in the message.
|
|
--- Use "if_many" to only show sources if there is more than one source of
|
|
--- diagnostics in the buffer. Otherwise, any truthy value means to always show
|

--- the diagnostic source. Overrides the setting from |vim.diagnostic.config()|.

--- - format: (function) A function that takes a diagnostic as input and returns a
|
|
--- string. The return value is the text used to display the diagnostic.
|
|
--- Overrides the setting from |vim.diagnostic.config()|.
|
|
--- - prefix: (function, string, or table) Prefix each diagnostic in the floating
|
|
--- window. If a function, it must have the signature (diagnostic, i,
|
|
--- total) -> (string, string), where {i} is the index of the diagnostic
|
|
--- being evaluated and {total} is the total number of diagnostics
|
|
--- displayed in the window. The function should return a string which
|
|
--- is prepended to each diagnostic in the window as well as an
|
|
--- (optional) highlight group which will be used to highlight the
|
|
--- prefix. If {prefix} is a table, it is interpreted as a [text,

--- string, it is prepended to each diagnostic in the window with no
|
