type t

The collection of TextMate grammars.

type grammar

A TextMate grammar.

type stack

The state of the code highlighter.

exception Error of string

The error message is purely informational and is not to be matched on.

type plist = [

| `Bool of bool
| `Data of string
| `Date of float * float option
| `Float of float
| `Int of int
| `String of string
| `Array of plist list
| `Dict of (string * plist) list

]

A plist document. This is the same plist type that is defined in the plist-xml package (as of version 0.3.0), but is reproduced here as not to depend on plist-xml.

val create : unit -> t

Create an empty collection of grammars.

val add_grammar : t -> grammar -> unit

Add a grammar to the collection.

val find_by_name : t -> string -> grammar option

Finds a grammar by its name attribute. Case-insensitive.

val find_by_scope_name : t -> string -> grammar option

Finds for a grammar by its scopeName attribute. Case-sensitive.

val of_plist_exn : plist -> grammar

Reads a TextMate grammar from a plist file. Raises Error if the plist does not represent a valid TextMate grammar.

val empty : stack

The initial state of the code highlighter.

type token

A token of code.

val ending : token -> int

The index of the character right after the last character of the token.

If tok is the first token of the line, it spans the substring from 0 to ending tok. If tok succeeds a token prev, tok spans the substring from ending prev to ending tok.

val scopes : token -> string list

The token's stack of TextMate grammar scopes.

val tokenize_exn : t -> grammar -> stack -> string -> token list * stack

Usage: let tokens, stack = tokenize_exn t grammar stack line

Tokenizes a line of code. Returns the list of tokens tokens and the updated tokenization state stack.

Precondition:

line must be a single line, including the newline character at the end.

Postconditions:

tokens is nonempty.
The ending of the last token in tokens is always String.length line.

Raises Error if it tries to match a malformed end or while regex.

Raises Error if it tries to access a local repository that doesn't exist in the file. Currently, it silently ignores includes of other grammars that don't exist in t.
