Dummy project to test various aspects of github / gitlab / bitbucket and integrations with it (e.g. Netlify).

Testing abuse of relative links to link to issues: #1.

MathJax loaded in output via Jekyll template _layouts/default.html.

Delimiters recognized by kramdown:

inline $$ \frac{kram}{down} \sum_0^\infty $$ text.

$$ \frac{kram}{down} \sum_0^\infty $$

The second is display math because it occurs alone in a block.

See also <katex.md> -> https://cben.github.io/sandbox/katex for using KaTeX instead of MathJax.

Gitlab syntaxes

inline $\frac{git}{lab} \sum_0^\infty$ text.

$$\frac{git}{lab} \sum_0^\infty$$

Single-dollar math?

• Is $\frac{tex}{math} \sum_0^\infty$ rendered?
• What about $10 to $20 prices?
• Adjacent text: non-$n^2$-secure ($n \log n$)?
• Whitespace inside: foo $ math $ bar?

Linking to headers

Test explicit anchor {#test-anchor}

Does github support explicit header anchors? link to #test-anchor => No

Does GitHub automatically generate ids for headers? Yes — doc

• The links have no prefix: link to #linking-to-headers
• However the actual anchor is prefixed id="user-content-linking-to-headers"! link to #user-content-linking-to-headers
  Interesting, this prefixed link scrolls to a slightly different place than #linking-to-headers.
  I'm not sure how the unprefixed #linking-to-headers link works at all, perhaps by JS parsing the URL?

Links in SVG?

img tag: markdown image syntax: inline svg tag:

<title>G</title> <title>link</title> link

See also #8 — SVG links don't work in issue comments either.

Right-to-left עברית

נזכיר שעקומה מסדר שני היא בעלת מבנה כללי. $$a_{1,1}x^2+2a_{1,2}xy+a_{2,2}y^2+a_1x+a_2y+a=0$$

תרגיל. צייר את העקום $$.4x^2+2\sqrt{3}xy+2y^2-6=0$$

פתרון כדי להבין את מבנה העקום נאפס את המקדם של המונום $$xy$$ באמצעות טרנספורמציה מתאימה בין מערכות קורדינאטות. לפי הנוסחא שפיתחנו בהרצאה,תמיד ניתן לסובב את מערכת הקורדינאטות ב $$\theta$$ מעלות נגד כיוון השעון ולקבל מערכת מתאימה $$O'$$ שבה העקום הוא בעל צורה קנונית. ...

This is a ## header(?) prefixed with a space, let's see if it counts as header?

LaTeX sync playground

As of 2015–2016 my recommendadion for collaborative LaTeX editing is Overleaf (former WriteLaTeX). It has real-time collaborative editing but you can also work offline using Git.

For co-authors that want to work offline / use their favorite editor, but that don't want to learn Git, Github is a good place because any github repo can transparently also be cloned over SVN!

But then what if you want to also edit offline?

• You can push/pull local clone to both overleaf and github. Tip: overleaf creates git commits when you save in overleaf UI, but also on demand when you git fetch / git pull. So git fetch frequently to force more history :-)

• https://ShareLaTeX.com supports direct github sync. (ShareLaTeX is mostly open source but this feature isn't.) TODO: try it.

• I've enabled github sync for this repo on Authorea. That's where all the .tex files come from (and layout.md which is not really markdown but list of files).

P.S. shameless plug: if anybody is reading this and looking for collaborative markdown editing with math, try https://Mathdown.net.
