OJS Plugin: LatexRender support

[rmurphy00]

I keep getting the following error:

Code: Select all

WARNING: The required tools are missing or incorrectly configured. See plugins/generic/latexRender/lib/otherPHP/latexrender/class.latexrender.php for the configured locations of these tools.

All I have done is untarred the LatexRender plugin tarball into the plugins/generic folder. When I go to enable the module (under generic modules), I get this error. I couldn't find a README; am I missing something?

Thanks!

Hi Ray,

Look in plugins/generic/latexRender/lib/otherPHP/latexrender/class.latexrender.php -- there are some tools there that need to be available for the plugin to work, e.g. "latex", "dvipng", and "identify". If they're on your system, but you still see this message, double-check that the directories in class.latexrender.php are correct.

Hi Alec,

Thanks for the reply. Is there some documentation, or README, or some file that explains in detail all of the requirements? Or perhaps, a file with instructions?

Thanks a lot!

Hi Ray,

The LatexRender documentation is included in lib/README in the plugin package; the plugin self-documents with the following:

This plugin enables server-side rendering of embedded LaTeX content in article titles and abstracts. LaTeX snippets can be embedded inline using $snippetHere$, or in an indented block using $$snippetHere$$. Non-delimiting dollar signs must be escaped with a backslash, e.g. "\$5.00".

This plugin works really fine. Congratulations!

However, I would also need to include it in OCS. Is there any guide to adapt the OJS plug-in to OCS?
Thanks in advance.

Hi gonetil,

As far as I'm aware, nobody has ported this plugin to OCS. Much of the work will be a simple change in terminology, i.e. $article => $paper, $section => $track, etc, but there will be some coding involved. If you do undertake a port of the plugin to OCS, please consider contributing it back to the community.

I have adapted this plugin to work with OCS. I am still testing it, but it seems to work just fine. The code is quite the same, I've modified a few getters, setters and templates to work with it. Hope it works fou you, testers are welcome.
I am using: OCS 2.1.1.1 (octubre 20, 2008 - 11:09 ) Ubuntu Linux, PHP 5.2.4-2ubuntu5.5, Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.5 with Suhosin-Patch
and mysql 5.0.51a-3ubuntu5.4-log

Hi!

The latexRender plug-in was written while OJS version 2.2 was current. All plug-ins written for 2.2 should also work in 2.3 except for two limitations:
- They may cause deprecation warnings in the log if deprecation logging is enabled
- They cannot be installed with the new web-based installer interface.

I've added the necessary changes to make the latexRender plug-in 2.3 web-installable (added a version.xml file) and changed a few lines of code to get rid of the deprecation warnings. Please also make sure you have seen and patched http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=5505.

Please be aware that the attached version will no longer work in OJS 2.2.
