MimeTeX-Talk

I've made the update to get this working under Perl5.5

Markup('{$', 'directives',
  '/\\{\\$(.*?)\\$\\}/e',
  "Keep(Mimetex(PSS('$1')))");

To

Markup_e('{$', 'directives',
  '/\\{\\$(.*?)\\$\\}/',
  "Keep(Mimetex(\$m[1]))");

Be careful with the quote levels on this change (in particular, you need to remove them from PSS(\$m[1]).

Also, if you are having trouble getting the mimetex.cgi script to run:

1. Make sure that it is in a place where your server recognizes as appropriate for running scripts (e.g., a cgi-bin directory).
2. Make sure it has the proper execute permissions (755 on a Linux server), including the right http_context if your system uses selinux permissions (Run chcon --type=httpd_fastcgi_script_exec_t mimetex.cgi )
3. Make sure that the mimetex.cgi path is set correctly in the config.php file. I use $MimetexUrl = '../../cgi-bin/mimetex.cgi'; . You can check this by viewing source on the page created by pmwiki. It should have an <img> tag with a link to the cgi program. Verify that that is the correct path on your server.

I hope this is of help to people.

You need to remove the call to the PSS() function when updating for PHP 5.5 otherwise you'll lose some of your backslashes (corrected). --Petko March 23, 2016, at 09:55 PM

Can this be enabled in MimeTeX-Test? page, I can replace the original page once examples from it are migrated ? VKrishn January 26, 2023, at 11:06 PM
