 | |
| --- (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>
 | |
| ---   vim.diagnostic.config({virtual_text = true})
 | |
| --- </pre>
 | |
| ---
 | |

| --- <pre>
 | |
| ---   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) Prepend diagnostic message with prefix.
 | |
| ---                       * 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:

 | |
| ---                       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
 | |
