:+1: Yes. But please make that an optional feature that can be switched on or off via config It should perform replacements based on the AST
From @HowardCohl on July 17, 2015 16:8
Ha. An optional parameter for the main feature the program is specifically designed to perform. Isn't that like "print -print x", saying we should print x but only if the -print option is specified. :)
What's an AST?
From @physikerwelt on July 17, 2015 17:25
AST is abstract syntax tree.
parameter:To keep the program compatible to the wikimedia texvcjs program this would be nice to follow a modular design here. I would not pass the parameter as commandline argument but define that in a config file

print -print reminds me to git clean
You said that
\Biggl(a)\Biggr)_n
should return \pochhammer{a}{n}, but there seems to be an extra right parenthesis there (both a ")" and "\Biggr)", is this intentional?
From @HowardCohl on July 22, 2015 13:34
You're right Claude. It should be \Biggl(a\Biggr)_n
. I will correct the original comment.
But of course these are just examples of ways to insert parentheses. There are many more such as:
\big(...\big) \Big(...\Big) \bigg(...\bigg) \Bigg(...\Bigg)
\bigl(...\bigr) \Bigl(...\Bigr) \biggl(...\biggr) \Biggl(...\Biggr)
\left(...\right)
(...)
I have tried doing this but with limited success. I was able to make it perform the replacement if it was a single character as a and n but the parsing does not work if it is a LaTeX command or multiple characters due to the way that the program handles parentheses and underscores normally. I eventually got pretty frustrated and started working on issue #18, and will probably come back to it after I completely solve issues #15, #18, and #16.
Can the command inside the parenthesis be a string of more than one character? For example, could it be like this:
(abcd)_{\commandname}
Also, if the second argument was like this:
(a)_abcd
should I return \pochhammer{a}{abcd} or \pochhammer{a}{a}?
From @HowardCohl on September 18, 2015 21:32
Yes you could have (abcd)_{\commandname}
for instance you could have (abcd)_{\alpha}
or you could have (abcd)_\alpha
. This works also.
If you have (a)_abcd
then you should return \pochhammer{a}{a}bcd
. Does this make sense?

Once you finish this, it should be easy for you to implement \qPochhammer.
This will be, 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
.

Github has new (simplified way of tracking the status) You can create lists of the sub-issues that need to be resolved.
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
as well as
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.
