Removing necessary spaces

From @ClaudeZou on March 30, 2016 20:11

texvcjs removes spaces that are necessary for the LaTeX to work.

macro replacement for Jacobi polynomial

From @ClaudeZou on August 14, 2015 18:51

P_n^{(\alpha,\beta)}(x) -> \Jacobi{n}{\alpha}{\beta}@{x}

macro replacement for Laguerre polynomial

From @ClaudeZou on August 14, 2015 18:53

L_n(x) -> \Laguerre{n}@{x}
L_n^{(\alpha)}(x) -> \Laguerre{n}[\alpha]@{x}

This is an example of a macro with an optional parameter.

Implement macro replacement for \pochhammer{a}{n}

From @HowardCohl on July 15, 2015 18:22

If you have some math in LaTeX such as

(a)_n this string should be replaced by \pochhammer{a}{n}.

Similarly

\left(a\right)_n 
\Biggl(a\Biggr)_n
(a)_{n}
(a)_{{n}}
(\mu)_\alpha

as well as

(\;a)_{\ n}

should also be replaced by \pochhammer{a}{n}

\left( and \Biggl( are all ways to represent parentheses.
; and \ are space delimiters and should be ignored.

Replace sinh x with \sinh@@{x}

From @HowardCohl on August 11, 2015 20:3

There are also equivalents such as:

\sinh\alpha -> \sinh@@{\alpha}
\sinh\,x -> \sinh@@{x}
\sinh\!x ->\sinh@@{x}

(Claude is currently working on this, so we felt we should create an issue.)

Add macro replacement for LaTeX functions similar to \sinh

From @ClaudeZou on September 30, 2015 20:52

Add the replacements for \sinh to the functions needed.

Make --semanticLaTeX switch

From @physikerwelt on October 7, 2015 7:47

Add a CLI option to control if @ -symbols are used in the output
Constraint: One should not need to recompile to switch the behaiviour.
PS:
This would be also helpful to solve wikimedia/mediawiki-services-texvcjs#7 which is somehow stalled because I don't know how to implement a --MathJax switch

Implement \qPochhammer{a}{q}{n}

From @HowardCohl on April 1, 2016 19:58

For instance,

(a;q)_n to be replaced with \qPochhammer{a}{q}{n}

It has to look for a semicolon to separate the a and the q.

Generate test cases

We need to generate test cases for texer @notjagan

@physikerwelt could you clarify how this could be formatted/inputted in to the program (if that matters) and how we might implement this?

macro replacement for Jacobi polynomial

P_n^{(\alpha,\beta)}(x) -> \Jacobi{n}{\alpha}{\beta}@{x}

macro replacement for Jacobi elliptic function

From @ClaudeZou on August 14, 2015 18:54

{\rm sn}(x,k) -> \Jacobisn@{x}{k}

This is an example with more than one argument.

Create a function that discovers math mode within a .tex file

Create a test like that

    {
        input: 'This is a test $a$ and $b$',
        options: {},
        out: ['$a$','$b$']
    }

Parse lists in LaTeX macros

At the moment, we have macros that use lists of elements surrounded by parentheses and delimited by semicolons/commas. These elements are sometimes not covered by lit; for example, \cos\tha is not matched since it is two literals chained together.

As such, using lit in the auto-generated rule doesn't find occurrences of the macro when a case like this appears.

We attempted to create a new rule that accepted such lists and added it as an option to lit but the return types were radically different and the program was unable to handle the lists properly.

As of now, we aren't sure of how we should approach a fix to this problem.
