Add More Colors

I learned on Stack Exchange that Keynote is using Blahtex to render Latex. I try to match colors in my latex equations with keynote colors, but this is proving impossible at the moment. Would it be possible to add more colors therefore - in particular some darker blues?

Maybe more ambitiously, could the keynote standard colors be matched exactly?

Mozilla tracking bug

I don't know the current status of Blahtexml, but the David Harvey had reported many Mozilla bugs in the past. There is a list here

https://www.mediawiki.org/wiki/Extension:Blahtex/Bugs/Bugs_in_browser_MathML_support/Gecko

and a quick search shows that many are still referenced in the source code:

https://github.com/gvanas/blahtexml/search?q=mozilla
https://github.com/gvanas/blahtexml/search?q=firefox

The Mozilla MathML team has fixed many of these bugs (Blahtexml should probably be tested with a recent version of Gecko and the comments in the source code updated) but we are always interested to get more feedback:

https://bugzilla.mozilla.org/buglist.cgi?f1=see_also&list_id=11167342&o1=substring&query_format=advanced&v1=https%3A%2F%2Fgithub.com%2Fgvanas%2Fblahtexml%2Fissues%2F4

I'm opening this as a tracking bug.

Does not compile with GCC 4.7

Hello,
Not sure if this is being maintained here anymore, but unistd.h is not imported by default anymore in gcc 4.7. I notice the 2 files this import is needed there is a guard clause for if this is being compiled for OS X. Removing those guard clauses allows it to compile normally.

Found crashes with --mathml by fuzzing with afl++

Hello!

I've ran afl++ on commit 92f2c5f (current master) and it has found the following inputs to crash the blahtex interpreter when passing --mathml as an argument.

{{}{}}, ((^{ {}{}}, ?i^?k^{{}{}}, {}{}, {}{}{}, \!\,, ^{^{{}{}{}}}.

To reproduce crashes: echo "{}{}" | ./blahtex --mathml

I've fuzzed on Linux ass 5.10.0-18-686-pae #1 SMP Debian 5.10.140-1 (2022-09-02) i686 GNU/Linux on Intel T2400 CPU. No other platforms have been tested.

I didn't test for the impact those crashes have on security or integrity. Apple pages documents containing such inputs show no visual indication of library crash as tested on iPad. As I do not have access to one, I cannot fully verify, nor do I know how this library is used by the software.

Tarball with afl++ output: http://upload.sijanec.eu./blahtex.tar.gz

Status of the project

Hello 👋 . I'm a maintainer for the Homebrew project. We are considering deprecating blahtexml due to the lack of a new release for a number of years. I've noticed recent commits, so wanted to clarify the status of the project. Can we expect new releases?
