REGEX DIALECT / GROUP BUDGET \u{2014} read before editing any `#match?` here.\n;\n; Neovim evaluates `#match?` with `vim.regex()`, prepending `\\v` (very magic)\n; whenever the pattern does not already start with `\\v`/`\\m`/`\\M`/`\\V`. Two\n; consequences, both of which have bitten this file:\n;\n; 1. Every bare `(` is a CAPTURING group, and Vim\'s NFA engine allows at\n; most 9 of them. A tenth aborts the whole query with\n; `E872: (NFA regexp) Too many \'(\'` \u{2014} highlighting then stops dead at\n; that predicate and the rest of the buffer renders unhighlighted.\n; A single combined alternation here once used 14 groups. It is now\n; split into several patterns; the query engine ORs separate patterns,\n; so the accepted set is unchanged. Keep each pattern well under 9.\n;\n; 2. Write `(`, `|`, `)`, `?` BARE. Do NOT write `\\(` / `\\|`: under the\n; auto-prepended `\\v` those are LITERAL characters, so the predicate\n; would compile cleanly and then silently match nothing.\n;\n; This bare dialect is read identically by Vim\'s very-magic mode and by Rust\n; regex (tree-sitter CLI, Helix, Zed), so it stays portable across engines.\n;\n; The `\\w+_` prefix is deliberate and must not be narrowed to `STATS_`: the\n; prefix is user-selectable (`stats \u{2026} prefix \"FOO\"`, `set fit prefix`).\n\n; stats: moments \u{2014} <prefix>_mean/_stddev/_skewness/_kurtosis (+_err) (+_x/_y)\n((identifier) @variable.builtin\n (#match? @variable.builtin\n \"^\\\\w+_(mean|stddev|skewness|kurtosis)(_err)?(_x|_y)?$\"))\n\n; stats: distribution summaries (+_x/_y)\n((identifier) @variable.builtin\n (#match? @variable.builtin\n \"^\\\\w+_(min|max|sdd|adev|median|sum(sq)?|(lo|up)_quartile)(_x|_y)?$\"))\n\n; stats: regression, extents, counts, column metadata\n((identifier) @variable.builtin\n (#match? @variable.builtin\n \"^\\\\w+_((slope|intercept)(_err)?|size(_x|_y)|column(s|_header)|records|headers|outofrange|invalid|blank|blocks|correlation|sumxy)$\"))\n\n; GPVAL_* / MOUSE_* / FIT_* / ARG*\n((identifier) @variable.builtin\n (#match? @variable.builtin\n \"^((GPVAL|MOUSE|FIT)_|ARG)\\\\w+$\"))\n\n; fixed-name built-ins \u{2014} plain string comparison, never reaches a regex engine\n((identifier) @variable.builtin\n (#any-of? @variable.builtin \"GNUTERM\" \"VoxelDistance\" \"GridDistance\"))\n\n; -----------------------------------------------------------------------\n; Array definitions\n(def_array\n \"array\" @keyword.function)\n(array\n (identifier) @function)\n; -----------------------------------------------------------------------\n; Literals\n\"NaN\" @constant.builtin\n(number) @number\n(string_literal) @string\n(escape_sequence) @string.escape\n(format_specifier) @string.special\n\n; watchpoint target (`watch y=50`): the axis/expression name being watched\n(plot_element target: (identifier) @variable.member)\n";Expand description
