I'm trying to convert latex code embedded in an HTML document (Intended to be used with a Javascript shim) into MathML. Pandoc seems like a great tool. Following this example: http://pandoc.org/demos.html,
pandoc input.html -s --latexmathml -o output.html
Produces no change in the file. I even made a barebones blank HTML file with various text expressions to test; no change in the output. What am I missing?
http://math.etsu.edu/LaTeXMathML/ This site, linked to by Pandoc, appears to show documentation for a standalone case, but it uses a JS shim instead of outputting the MathML directly. (I think it has the browser render dynamically-rendered MathML, but doesn't actually output it to the file) It's also missing some basic functionality, like own-line functions with \begin{equation}.
I've spent several hours googling ways to accomplish this. Any ideas? The only fully-working solution I've found is https://www.mathtowebonline.com/ This website. There's also a python module called latex2mathml, but it's also missing large chunks of the spec.
You'll need the --mathml flag (not the --latexmathml flag) to generate MathML and the tex_math_dollars extension enabled for reading the math between dollar signs:
$ echo '<p>$$x = 4$$</p>' | pandoc -f html+tex_math_dollars -t html --mathml
<p>
<math display="block" xmlns="http://www.w3.org/1998/Math/MathML">
<semantics>
<mrow><mi>x</mi><mo>=</mo><mn>4</mn></mrow><annotation encoding="application/x-tex">x = 4</annotation>
</semantics>
</math>
</p>
Or maybe you're better off using somehting like snuggleTeX or LaTeXMathML.js...

I want to print out some code on paper including syntax highlighting.
After some research, I found out, that I could do this with pygments and enscript, but don't know how to combine these tools. Obviously there must be someone out there, who has done this before. Or is there a better way of doing it?
BTW: I know I can do this in vim too, but I don't like how it prints out JSON files.
Depending on what output format you want, you may not actually need enscript. Pygments can render your input to various formats, including html, rtf, latex and various others.
You can call pygments on the command line passing input file and output format.
To let pygments render a json file to html use ...
$ pygmentize -f html -o foobar.html foobar.json
To render to rtf use ...
$ pygmentize -f rtf -o foobar.rtf foobar.json
Available output formats are listed at:
http://pygments.org/docs/formatters/
I'm currently using BlueCloth to process Markdown in Ruby and show it as HTML, but in one location I need it as plain text (without some of the Markdown). Is there a way to achieve that?
Is there a markdown-to-plain-text method? Is there an html-to-plain-text method that I could feel the result of BlueCloth?
RedCarpet gem has a Redcarpet::Render::StripDown renderer which "turns Markdown into plaintext".
Copy and modify it to suit your needs.
Or use it like this:
Redcarpet::Markdown.new(Redcarpet::Render::StripDown).render(markdown)
Converting HTML to plain text with Ruby is not a problem, but of course you'll lose all markup. If you only want to get rid of some of the Markdown syntax, it probably won't yield the result you're looking for.
The bottom line is that unrendered Markdown is intended to be used as plain text, therefore converting it to plain text doesn't really make sense. All Ruby implementations that I have seen follow the same interface, which does not offer a way to strip syntax (only including to_html, and text, which returns the original Markdown text).
It's not ruby, but one of the formats Pandoc now writes is 'plain'. Here's some arbitrary markdown:

(Not sure how to turn off the syntax highlighting!) Here's the associated 'plain':

You can get an idea what it does with the different elements it parses out of documents from the definition of plainify in pandoc/blob/master/src/Text/Pandoc/Writers/Markdown.hs in the Github repository; there is also a tutorial that shows how easy it is to modify the behavior.
Something that I've had a good hard look for and I have not been able to find, is how to efficiently obtain a hard copy of Javadocs? Obviously, one solution is simply to navigate to each page and execute a browser print, but there's got to be a better way! Do you guys have any ideas?
You can use DocBook Doclet (dbdoclet) to create DocBook XML from your JavaDoc Comments. The DocBook XML can then be transformed to PDF or (Singlepage-)HTML.
You can call the tool from the commandline. Point it to your class files and it will generate the DocBook XML. This works similar to the javadoc command which will generate the JavaDoc HTML. Example:
./dbdoclet -sourcepath ~/my-java-program/src/main/java -subpackages org.example
The result is a DocBook XML file in a dbdoclet subdirectory which can be used to create a PDF or HTML file. This can also be done from the command line; I am using the docbkx-maven-plugin for this.
You can do mass conversions with it, but it would require some time to make it work the way you want.
I've recently taken on a project of document conversion to HTML. That is, a client gives me a .DOC file, and I need to convert the contents to one long HTML file - no styling, no CSS, just clean HTML with paragraph tags, header tags tags, etc.
I found an application that does a pretty good job of automating the first part of it. The problem is that I need to do some advanced find and replace based on strings using variables.
For instance, I have footnotes that were converted properly. They're currently displayed as superscript numbers with the
I'd like to change how the footnote is displayed. Instead of a superscript number 6 for the 6th footnote, I'd like it to show (Note 6)
To do that on the entire document (hundreds of footnotes), I'm wondering if I can do something like:
FIND:
<sup><a name="FN[0-9]" href="FNR[0-9]">[0-9]</a></sup>
REPLACE:
<a name="FN%1" href="FNR%2">(Note %3)</a>
The problem is, I can't find a Find and Replace tool that lets me maintain the variables in the replace area. All I get is the superscript 6 appearing as (Note %3), as well as every other footnote doing the same thing.
Anyone have any ideas on how I can accomplish my task efficiently?
In Perl it would look roughly like this on the command line (I have NOT tested this):
perl -i -p -e's{<sup><a name="(FN\d)" href="(FNR\d)">(\d)</a></sup>}{<a name="$1" href="$2">(Note $3)</a>}' filenames....
-i says "Edit this file in place", -p means "print each line after we do whatever is in the -e switch".
That's assuming you're only looking for a single digit where you have [0-9]. If you want to match FN427, then you change (FN\d) to (FN\d+), for example.
This also assumes that the HTML that are you parsing looks EXACTLY LIKE THAT. If you get some HTML that is <a href=... name=... (with the attributes in opposite order than you have) then it will break. In that case, you'll want to use an HTML parser.
I hope that gives you enough to start with.
I'm going to a farm. I think there are no computers there, and my laptop is broken. I want to print out the code of some of my projects on A4 paper so I can review it while I'm there. It would be nice if it was printed with syntax highlighting.

Use M-x <command> to invoke commands by name. Use C-h f <command> for help on a command and also to learn what (if any) keybinding it has.
a2ps tool produces nice PostScript files for program listing printing.
Vim has :TOhtml command which produces HTML with current open file highlighted according to Vim syntax coloring. GVim has Syntax -> Convert to HTML menu for this.
If you use LaTeX, look at listings package (pdf documentation at CTAN). It's a very good solution for including your code in documentation/presentation.
All these tools support syntax of many programming (and non-programming) languages.
