What a rule matches. Ordering of SyntaxManifest::rules is significant: earlier rules win, in every target format.

Variants

Words

Whole-word alternation, guarded by identifier boundaries.

Fields

lexemes: Vec<String>

followed_by: Option<String>

When set, the word only counts glued to what this regex matches — the delimiter the parser consumes along with it (c(, seq[, R {). Without it a variable named c would be colored as the vector constructor.

Symbols

Symbol alternation, emitted longest-first so <= beats <.

Fields

lexemes: Vec<String>

Annotations

@-prefixed annotations — a word rule whose \b prefix guard has to be dropped, since @ is not a word character.

Fields

lexemes: Vec<String>

Sigils

The kind sigils, expanded by each generator from SyntaxManifest::sigils.

Match

A raw regex, in the ECMAScript-ish dialect TextMate/Oniguruma and Shiki’s JS engine both accept.

Fields

pattern: String

vim: String

The same rule in Vim’s \v (very-magic) dialect. Vim’s regex engine diverges from TextMate/Oniguruma too far for one pattern to serve both: lookaround is postfix (atom@=/atom@! instead of (?=atom)/(?!atom)), and in \v mode bare </> mean word-boundary while a literal </> character needs escaping — the opposite of \b. Kept side by side with pattern so both targets are generated from the same rule instead of one being hand-transcribed later.

Span

A begin/end span (strings).

Fields

begin: String

end: String

escapes: bool

Whether \\. escape sequences are highlighted inside.
