Simple Perl scripts which use regex search and replace to in-place convert Latex markdown files (which use $[MATH]$
and $$[MATH]$$
) to Gitlab markdown (which uses $`[MATH]`$
and ```math [MATH]```
and vice versa.
One caveat: the $$[MATH]$$
style should have the math environment delimiters on separate newlines, so this works:
$$
[MATH]
$$
but the below and similar variations don't:
$$[MATH]$$
Additionally, the very first character in the file should not be $
.
