mitocw / latex2edx Goto Github PK

A GitHub issue isn't exactly the right forum for this, but I figured it would be helpful to link a Docker-based installer in case anyone is struggling to get the right dependencies installed these days:

(ODL, feel free to roll all/part of the above into this repo if it would be helpful)

Hi All, has anyone given any thought to supporting incremental builds to help speed up build times?

I am trying to install latex2edx on ubuntu (18.04), but I am having difficulties.

Which OS are you using? I am trying to actually create a docker container, so it is easier to use another os. I tried your documentation and seem to fail succeding.

Would be great to post a concrete example that shows how to do it. The README, somehow does not work.

There should be an option for the /includegraphics command to include alt and longdesc attributes.

Dear,

I am preparing a Calculus course, and I would like to adapt some resources from the course MITx: 18.01.1x Calculus 1A.

Here I am wondering whether it is possible to convert files in the other direction, i.e., from a web page from edx into a LaTeX file.

Thank your very much,
Best,
Hongying

The LaTeX non-breaking space character, ~, is presently not handled by the abox script.

When I try to convert a file using latex2edx on my MacOSX, I see the following errors. What am I missing?

$ latex2edx filename.tex
WARNING: Cannot find unidecode lib. Expect issues with index sorting
WARNING: No Python version of xcolor.sty was found
WARNING: Could not find any file named: xcolor.sty
WARNING: unrecognized command/environment: color
/bin/sh: dvipng: command not found
/bin/sh: dvi2bitmap: command not found
/bin/sh: gs: command not found
/bin/sh: gs: command not found
/bin/sh: cgpdfpng: command not found

If x1 is the number of variable in python,

[ \lim_{\x \to $x1} f(x)]

does not convert $x1 properly.

Is there any way to show it correctly?

Several content creators have mentioned issues with their LaTeX not generating xml without first appending and prepending newlines to their latex2edx specific commands.

During the installation process, plastex 2.0 is installed automatically, which is dependent on Python3, whereas latex2edx depends on python 2.7. While the installation completes without an error (with ptyhon 2.7, plastex 2.0), there is a runtime error coming from the version mismatch.

By installing an earlier version of plastex (e.g., 1.0), the package runs as expected. However, we have not checked if there are bugs fixed in the plastex package between 1.0 and 2.0, and if running an earlier version of plastex could affect latex2edx performance.

The function set_about has a variable xabout. Inside the function, there is a typo, xbout. However, this function is never called (at least within xbundle), even in tests.

Should the function be removed, or the typo fixed? Also, this same typo exists in all versions of xbundle I've seen (xbundle, latex2edx, edx2course_axis).

From one of our users:

It seems that latex2edx cannot handle any package name other than edXpsl. I modified this package and renamed it, but I was unable to use the renamed package. Even when I copied the original package and simply renamed it, I was unable to use the renamed package that was identical to edXpsl. It may be convenient to allow users to use a package name that differs from edXpsl. Note that pdflatex worked fine regardless of the package name, but latex2edx did not.

My own edx https://sandbox.etu.ru uses xblocks with latex https://studio-input-filter.mitx.mit.edu/latex2edx?raw=1 to compile mathcode. What can I do to make compilation on the local server? After installing repo mitocw/latex2edx what should I do?

$.ajax({
          url: "https://studio-input-filter.mitx.mit.edu/latex2edx?raw=1",
          type: "POST",
          data: "" + hlsdata,
          crossDomain: true,
          processData: false,
          success: function(data) {
              xml = data.xml;
              if (xml.length == 0) {
                  alert('Conversion failed!  error:' + data.message);
              } else {
                  // If a parent CodeMirror editor is open (LaTeX problem being edited), set the text
                  // there. Otherwise, set the text in the active TinyMCE Editor for the case
                  // of an HTML component being edited.
                  var parentCodemirrorEditor = el.closest('.xblock-studio_view').find('.CodeMirror-wrap');
                  if (parentCodemirrorEditor.length > 0) {
                      parentCodemirrorEditor[0].CodeMirror.setValue(xml);
                  }
                  else if (window.tinyMCE !== undefined && window.tinyMCE.activeEditor !== undefined) {
                      window.tinyMCE.activeEditor.setContent(xml);
                  }
                  save_hls(el);
              }
          },
          error: function() {
              alert('Error: cannot connect to latex2edx server');
          }
      });
