-# Highlight.js CDN Assets
-
-[](https://packagephobia.now.sh/result?p=highlight.js)

-**This package contains only the CDN build assets of highlight.js.**
-
-This may be what you want if you'd like to install the pre-built distributable highlight.js client-side assets via NPM. If you're wanting to use highlight.js mainly on the server-side you likely want the [highlight.js][1] package instead.
-
-To access these files via CDN:

-**If you just want a single .js file with the common languages built-in:

-## Highlight.js
-
-Highlight.js is a syntax highlighter written in JavaScript. It works in
-the browser as well as on the server. It works with pretty much any
-markup, doesn’t depend on any framework, and has automatic language
-detection.

- Created to solve the key deficiently with MultiRegex - there is no way to

- ignored. An example: if we matched say the 3rd regex in a large group but
- decided to ignore it - we'd need to started testing again at the 4th
- regex... but MultiRegex itself gives us no real way to do that.
-
- So what this class creates MultiRegexs on the fly for whatever search
- position they are needed.
-
- NOTE: These additional MultiRegex objects are created dynamically. For most
- grammars most of the time we will never actually need anything more than the
- first MultiRegex - so this shouldn't have too much overhead.
-
- Say this is our search group, and we match regex3, but wish to ignore it.
-
- regex1 | regex2 | regex3 | regex4 | regex5 ' ie, startAt = 0
-
- What we need is a new MultiRegex that only includes the remaining
- possibilities:
-
- regex4 | regex5 ' ie, startAt = 3
-
- This class wraps all that complexity up in a simple API... `startAt` decides
- where in the array of expressions to start doing the matching. It
- auto-increments, so if a match is found at position 2, then startAt will be
- set to 3. If the end is reached startAt will return to 0.
-
- MOST of the time the parser will be setting startAt manually to 0.

- * never matched) but DOES NOT continue to match subsequent `contains`
- * modes. Abort is bad/suboptimal because it can result in modes
- * farther down not getting applied because an earlier rule eats the
- * content but then aborts.
- *
- * - The mode does not begin.
- * - Content matched by `begin` is added to the mode buffer.
- * - The parser cursor is moved forward accordingly.
- *
- * @ignore - Ignores the mode (as if it never matched) and continues to match any
- * subsequent `contains` modes. Ignore isn't technically possible with
- * the current parser implementation.

- Created to solve the key deficiently with MultiRegex - there is no way to
- test for multiple matches at a single location. Why would we need to do
- that? In the future a more dynamic engine will allow certain matches to be
- ignored. An example: if we matched say the 3rd regex in a large group but
- decided to ignore it - we'd need to started testing again at the 4th
- regex... but MultiRegex itself gives us no real way to do that.
-
- So what this class creates MultiRegexs on the fly for whatever search
- position they are needed.
-
- NOTE: These additional MultiRegex objects are created dynamically. For most
- grammars most of the time we will never actually need anything more than the
- first MultiRegex - so this shouldn't have too much overhead.
-
- Say this is our search group, and we match regex3, but wish to ignore it.
-
- regex1 | regex2 | regex3 | regex4 | regex5 ' ie, startAt = 0
-
- What we need is a new MultiRegex that only includes the remaining
- possibilities:
-
- regex4 | regex5 ' ie, startAt = 3
-
- This class wraps all that complexity up in a simple API... `startAt` decides
- where in the array of expressions to start doing the matching. It
- auto-increments, so if a match is found at position 2, then startAt will be
- set to 3. If the end is reached startAt will return to 0.
-
- MOST of the time the parser will be setting startAt manually to 0.
