SIGNS                                                   *diagnostic-signs*

Signs are defined for each diagnostic severity. The default text for each sign
is the first letter of the severity name (for example, "E" for ERROR). Signs
can be customized with |vim.diagnostic.config()|. Example: >lua

    -- Highlight entire line for errors
    -- Highlight the line number for warnings
    vim.diagnostic.config({
        signs = {
            text = {
                [vim.diagnostic.severity.ERROR] = '',
                [vim.diagnostic.severity.WARN] = '',
            },
            linehl = {
                [vim.diagnostic.severity.ERROR] = 'ErrorMsg',
            },
            numhl = {
                [vim.diagnostic.severity.WARN] = 'WarningMsg',
            },
        },
    })

When the "severity_sort" option is set (see |vim.diagnostic.config()|) the
priority of each sign depends on the severity of the associated diagnostic.
Otherwise, all signs have the same priority (the value of the "priority"
option in the "signs" table of |vim.diagnostic.config()| or 10 if unset).
