rd-lezer-tex

lezer-tex

This responsitory holds lezer-compatible TeX grammar for use with codemirror 6.

This package should be used in conjuction with lang-tex, but custom TeX language packs could use this as a parser.

Background

Since TeX is context-sensitive, we parse TeX according to a specific context. Specifically, we assume certain built-in macros are not redefined (such as \begingroup, \csname, \endgroup, and many others). In doing so, the context is clear, so we can interpret the built-in macros as usual without worry.

Features

This parser is particularly strong since it parses tokens in the same way TeX parses tokens. In particular, this allows built-in tokens (e.g. commands) to modify the parser as the input is read.

Commands

The following is a table of supported commands and the dialects they are supported in:

FAQ

Why is \blahblahblah not executable?

There are two reasons a given command may not be executable:

1. It is from a package.
2. It will destroy the parser.

Package commands are generally specific to a given document, so implementing the command generically would just increase the size of the parser.

For the second reason, more likely than not, the command will either increase the parser's runtime or make the parser unusable. For example, definition commands (such as \newcommand, \def, etc) can build inescapable loops for the parser.

If you would like a particular command to be executed (and you have thoroughly researched its ramifications), submit an issue and we will try to accomodate.
