# # Markdown TextMate language
#
# This file is the core grammar used to make TextMate languages
# for markdown and MDX.
# TextMate grammars are basically what syntax highlighting of *every* editor is
# built on: VS Code, Atom, Sublime, TextMate.
#
# This file is authored by humans.
# It is later processed by programs that perform several steps.
#
# ## How this file is processed
#
# ### Variables
#
# To make managing 150+ big expressions easier, we support reusable regex
# parts in the form of `variables`.
# They are used with a `var(xxx)` group, where in this case `xxx` refers
# to a variable name that the whole will be replaced with.
# The value is defined in this file too, at the `variables` record.
#
# Several of these values are injected when building by `build.js`.
# This is for example used to include the list of known gemoji names.
#
# ### Rule injection
#
# The embedded grammars used in fenced code are injected.
# The `commonmark-code-fenced-unknown` rule is copied and changed for about
# 55 common languages.
# Those are injected into the grammar and included in the
# `commonmark-code-fenced` rule.
#
# ### Conditions
#
# Each rule can have an extra `if` field, which will be removed from the final
# grammar.
# This field can be set to one or more conditions (`string` or `Array<string>`),
# which are enabled in `build.js`.
# They can be used to drop rules that belong to extensions (such as GFM,
# frontmatter, MDX).
# If a grammar is generated without any of the conditions specified by `if`,
# the rule will be dropped.
#
# ## How grammars work
#
# To learn more about developing and maintaining TextMate grammars,
# see:
#
# * <https://www.apeth.com/nonblog/stories/textmatebundle.html>
# * <https://macromates.com/manual/en/language_grammars>
# * <https://gist.github.com/Aerijo/b8c82d647db783187804e86fa0a604a1>
# * <https://gist.github.com/DamnedScholar/622926bcd222eb1ddc483d12103fd315>
#
# The grammar of the regexes used in grammars is *different* from the grammar
# of JavaScript regexes.
# Their grammar comes from `kkos/oniguruma`:
#
# * <https://github.com/kkos/oniguruma/blob/master/doc/RE>
# — regex docs
# * <https://rubular.com>
# — regex playground
#
# ## How do grammars in Linguist work?
#
# Importantly, terribly, `github/linguist` *does not* use `kkos/oniguruma`, it
# uses PCRE (Perl Compatible Regular Expressions), for performance reasons.
# As we want to ship our grammars to `github/linguist`, the expressions here
# need to be compatible with *both* oniguruma and PCRE.
#
# For more on PCRE, see:
#
# * <http://www.pcre.org/original/doc/html/pcrepattern.html>
#
# There are several differences.
# An important one is that oniguruma is aware of Unicode, whereas PCRE is not
# by default (and GitHub doesn’t enable Unicode), so in the former `\w` would
# match unicode letters and numbers too, whereas the latter only matches ASCII.
#
# PCRE also doesn’t support longer Unicode character properties, so you need to
# swap `\p{Cntrl}` for `\p{CC}`, `\p{Alnum}` for `[\p{L}\p{N}]`, `\p{Punct}`
# for `\p{P}`, etcetera.
#
# Another difference is in how subpatterns can be called:
# <https://github.com/github/linguist/issues/3291#issuecomment-381115027>.
#
# ## Inspiration
#
# This grammar is inspired by these ones around markdown:
# [`microsoft/vscode-markdown-tm-grammar`][vscode],
# [`textmate/markdown.tmbundle`][tm],
# [`atom/language-gfm`][atom] (archived),
# [`burodepeper/language-markdown`][bdp] (deprecated),
# [`SublimeText-Markdown/MarkdownEditing`][mde], and more.
# Some other interesting grammars to look at are:
# [`sveltejs/language-tools`][svelte],
# [`withastro/language-tools`][astro], and
# [`microsoft/TypeScript-TmLanguage`][ts].
