Stackedit: No more \newcommand in StackEdit 5

[petered]

In StackEdit 4 I just began each of my documents with a preamble that contained a bunch of custom commands. e.g.

$$
\newcommand{\pderiv}[2]{\frac{\partial #1}{\partial #2}}
\newcommand{\argmax}[1]{\underset{#1}{\operatorname{argmax}}}
\newcommand{\argmin}[1]{\underset{#1}{\operatorname{argmin}}}
\newcommand{\switch}[3]{\begin{cases} #2 & \text{if } {#1} \\ #3 &\text{otherwise}\end{cases}}
$$

I see that using \newcommand is no longer allowed in StackEdit 5 (guess because Katex is now used instead of MathJax?).

This is kind of a deal-breaker for me. Is there any workaround other than reverting to StackEdit 4? Maybe there's a way to make it use MathJax?

Yes the v5 uses katex. We have to wait for this ticket to be closed: https://github.com/Khan/KaTeX/issues/37

KaTeX is really behind MathJaX (Feature wise).
It hurts Students using StackEdit.

Any chance you give us the option to use MathJaX as it used to be?

Thank You.

[petered]

@RoyiAvital you can use the link https://stackedit.io/editor# to run StackEdit 4, which will allow \newcommand

[RoyiAvital]

@petered , Well then other features are missing (Dropbox).
I don't get the idea of reducing features between versions.
StackEdit was great because of its perfect Math support and that was the feature I paid for.
Breaking compatibility doesn't make sense in my opinion, I need to find other solution.

So far Visual Studio Code + Markdown Preview Enhanced extension are the closest I can get to StackEdit as it was.

I'm working on my project Moeditor, a local markdown editor app. Maybe I'll use StackEdit 5's core and add MathJax support.

Note that \newcommand has been implemented in the latest KaTeX: https://github.com/Khan/KaTeX/pull/1382

\newcommand still not working on stackedit5?

[petered]

Seems not yet, I still get:

KaTeX parse error: Expected 'EOF', got '\newcommand' at position 1: \̲n̲e̲w̲c̲o̲m̲m̲a̲n̲d̲{\pderiv}[2]{\f…

[benweet]

Upgraded to katex v0.10.0-rc.1.

[qx211]

Thanks, now \newcommand works within one "$$" but still not globally...

[RoyiAvital]

I still find this to be an issue (Taken from StackEdit landing page):

StackEdit used to have perfect compatibility with StackExchange network for Math.
Yet since the move to KaTeX in StackEdit 5.x this doesn't hold anymore.

I really wish for a MathJaX mode with proper scientific writing as we had before in StackEdit.
MathJaX can work with ID / Labels just like KaTeX.

I have been using hackmd for a while but they dont support working offline, so now I am trying stackedit. But without having \newcommand available, I will not take it up more seriously. Any other recommendations? Is there a system that supports offline work and \newcommand/full mathjax?

[RoyiAvital]

@alexhkurz , I use VS Code + MarkDown Preview Enhanced.
It works perfectly!

If you can skip the live preview, I think the best is Sublime Text + MarkDown Preview (By @facelessuser).

[alexhkurz]

thanks ... I am just trying VS Code + MarkDown Preview Enhanced ... looks good so far ...
