comment Workaround how to use expl3 functionality in tikz
I strongly suspect that the problem is due to the fact that in expl3 then : has the catcode of a letter but TikZ expects it to be other. One way around this is to define a token list containing a colon with catcode "other" and use that in place of the bare : in your code.

Better late than never ... it's now fixed on CTAN and in TL14.

The version on the TeX-SX LaunchPad page contains the fix. It just needs the documentation updating before being uploaded to CTAN. Download from bazaar.launchpad.net/~tex-sx/tex-sx/development/files

comment How to plot the absolute value of a hobby curve
The easiest way would be to draw it twice clipped to the upper region (and the second draw being reflected). The joins between the segments wouldn't be neat if you looked at them closely, but would that be a problem?

comment MathJax won't render 'bold' faces
Although MathJaX uses an input syntax based on LaTeX, it does not use TeX internally and so questions about MathJaX are usually not TeX-related and thus are off-topic for this site.

comment TikZ code no longer compiling
@SvendTveskæg You're not downloading the actual file! You're downloading the web page containing the file, together with all the javascript and HTML and other junk. From the link you put in your comment above, click "download file" to get the actual file.

@JosephWright This particular problem was caused by the removal of \fp_if_undefined from the fp segment. It's used because there are some numbers that the user can configure or can be left unassigned. So there needs to be a test for "not assigned" and \fp_if_undefined seemed the best way to accomplish that. The workaround is to assign these fps to \c_inf_fp at initialisation and test for that instead of undefinedness. Similar things have happened before.

@SvendTveskæg I just downloaded it from Launchpad to a new directory, ran tex hobby.dtx to generate the files (with no errors), took your code and it compiled with no problems. This is with TeXLive 2014, recently updated.

comment Rescale a character to fill a complete A4 page
@strpeter Does that matter? (If it's true, which I'm not convinced of as scaling is a fairly straightforward transformation.) I wouldn't say it was ambiguous though since if you like how your PDF viewer does it then you've nothing to worry about. So you can optimise it for your PDF viewer/printer and not worry about the fact that others might do something slightly different.

comment TikZ code no longer compiling
When I try your code with the hobby library loaded then I get an error about decorations, again probably missing some library. Even though you say you don't use TikZ, you know enough about LaTeX to know that when you cut-and-paste code, you need to get the preamble right!

Could you rerun the code with \usetikzlibrary{hobby} in the preamble and report the new error?
