sandbox

Dummy project to test various aspects of github / gitlab / bitbucket and integrations with it.

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.

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?

Gitlab syntaxes

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

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

Links in SVG?

img tag:
markdown image syntax: gravizo
inline svg tag:

See also https://github.com/cben/sandbox/issues/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. ...

Nested fenced blocks

Foo:
```ruby
block.parents.map {|b| b.language}
```
bar.

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.

Testing push via svn with master configured "Protect this branch", "Include administrators".
