Add ConteXt support

[PhML]

ConTeXt is a TeX macro package similar to LaTeX. It is included into TeXlive although it has its own standalone installation (more often updated and "is self-contained and can happily coexist alongside another installed TeX distribution").
It is based on LuaTeX (it has the same authors) and compiles to a pdf file simply by running "context myfile".
Having the choice to run either LaTeX or ConTeXt in ShareLaTeX would be nice.

This should be easy to implement. It will need to be added into sharelatex/clsi-sharelatex as a compiler option, with the appropriate command. A tricky part might be whether it can be made to run with latexmk - does anyone know if it can work with it?

Then it will need adding into sharelatex/web-sharelatex as an option alongside the other compilers. This should be trivial.

iirc context produces pdf output, so it may be as simple as calling latexmk with -pdflatex=context

[PhML]

@cwoac : I tried, it didn't work.
With -latex=context it compiles, but it is not made for that: latexmk do multiple passes while context already do everything needed.
In the end, it complains:

Latexmk: Did not finish processing file 'myfile.tex':
Log file 'myfile.log' appears to have wrong format.

Of course, latexmk expects LaTeX files. In fact, run context is equivalent to run latexmk except that it doesn't seem to have the -pvc option:
Continuously compile/watch source files in ConTEXt? from TeX stackexchange.

[jpallen]

We use latexmk to make sure that latex is run enough times, that bibtex is run, etc. If context manages these things itself then running it directly should be fine.

Any news on Context support in Shalatex? It's the only feature holding me back from using it to write classroom material and share with colleagues.

[jpallen]

This isn't as simple as we original hoped, sorry. It's unlikely that we'll implement this in ShareLaTeX in near future as there hasn't been much demand for it. Sorry.

I'd also love Context support. :-)

one very useful feature of ConTeXt support is the external figure support (which allows images from a URL without the use of -shell-escape)

ConTeXt would be awesome!!
I use both, they are good for different things.

I also now use sharelatex exclusively rather than my PC for Latex.
So ConText on share latex would be so good, I would pay more just for that.
If people knew how good it was many would convert.

Any update on this in 2021? I'd particularly like to use the external figure feature (as mentioned above:

).

How can one go about doing this with Overleaf in the current state?

Adding ConTeXt support would be great.

Try to setup it like this:

1. Create a new project,
2. rename main.tex to output.tex,
3. set the Compiler to LaTeX (using the project menu),
4. create a new file, name it latexmkrc and put the following line into it:
   $latex = 'context --luatex --synctex --batchmode %S'
5. edit output.tex and put there eg.
   \starttext This is \CONTEXT. \stoptext
6. compile

Thank you @AnadeB, I will try it.
