* Make ParseNode `value` payload type-safe.
* Make defineFunction handlers aware of ParseNode data types.
* Add `type` to all function definitions to help determine handler return type.
* Added unit test for case caught only in screenshot test and fixed issue.
* Rename some symbol `Group`s to avoid conflicts with `ParseNode` groups.
Symbol `Group`s are also used as `ParseNode` types. However, `ParseNode`s of
these types always contain a raw text token as opposed to any structured
content. These `ParseNode`s are passed as arguments into function handlers to
create more semantical `ParseNode`s with more structure.
Before this change, "accent" and "op" were both symbol `Group`s and `ParseNode`
types. With this change, these two types (the raw accent token `ParseNode`, and
the structured semantical `ParseNode` are separated for better type-safety on
the `ParseNode` payload).
* stretchy: Remove FlowFixMe for a forced typecast that's no longer needed.
* Initial webpack config. Moving to ES6 modules. Some module cleanup.
* WIP
* WIP
* Removing commented out code.
* Removing old deps.
* Removing the build script (used for testing).
* Working tests.
* Switching to node api over cli.
* Updating per comments. Still need to fix server.js to properly run the selenium tests.
* Cleaning up the config.
* More cleanup.
* Bringing back server.js for selenium tests.
* Bringing back old dependencies.
* Adding back eslint rules for webpack config. Final cleanup for webpack config.
* Pointing to correct pre-existing module versions. Adding some extra logic to server.js to ensure it gets transpiled properly.
* Getting make build to work again. Updating package.json with some shortcut scripts.
* Resolving conflict.
* Reverting back to commonjs modules.
* Removing extra spaces in babelrc
* Add SourceLocation to encapsulate Token/ParseNode debug information.
* Specify concrete Token text type as it captures type mismatches.
* Responded to comments.
* Add eslint-plugin-flowtype. Fix#844
Using the recommended settings for plugin.
This involved adding some spaces to some existing union types.
* Upgrade to eslint@4, fix spotted bugs
Switched to indent-legacy to allow e.g. comments to have extra indents.
* Add babel transform-class-properties to have static class properties
* Upgrade Lexer and Parser files to use ES6 classes
* Update eslint max line length to 90 character (more indent because of using ES6 classes)
* Upgrade eslint and jasmin to support ES stage-2 features
* Use static properties to place constants near their functions
* Migrate all remaining sources to ES6 syntax
* Increase eslint max line length to 84
* Remove non-babelified endpoint in dev server.js
* Clean up server.js functions after removing browserified
* Make screenshotter not to use babel endpoint as we babelify everything now
* Introduce MacroExpander
The job of the MacroExpander is turning a stream of possibly expandable
tokens, as obtained from the Lexer, into a stream of non-expandable tokens
(in KaTeX, even though they may well be expandable in TeX) which can be
processed by the Parser. The challenge here is that we don't have
mode-specific lexer implementations any more, so we need to do everything on
the token level, including reassembly of sizes and colors.
* Make macros available in development server
Now one can specify macro definitions like \foo=bar as part of the query
string and use these macros in the formula being typeset.
* Add tests for macro expansions
* Handle end of input in special groups
This avoids an infinite loop if input ends prematurely.
* Simplify parseSpecialGroup
The parseSpecialGroup methos now returns a single token spanning the whole
special group, and leaves matching that string against a suitable regular
expression to whoever is calling the method. Suggested by @cbreeden.
* Incorporate review suggestions
Add improvements suggested by Kevin Barabash during review.
* Input range sanity checks
Ensure that both tokens of a token range come from the same lexer,
and that the range has a non-negative length.
* Improved wording of two comments
