If you want to generate LaTeX from Markdown, you can use Pandoc. Pandoc has various extensions to regular Markdown (including inline math, tables, etc.), so this gives you some flexibility when producing more complicated types of documents. In fact, Pandoc converts from Markdown to LaTeX to PDF when you choose PDF as the output format.
This is the same approach we're using at Wikipendium[1] for math-heavy article editing - Markdown with inline LaTeX math segments edited in a CodeMirror editor. It's cool to see others tackling the same problems in similar ways.
We use Mathjax[2] for rendering LaTeX client side, but have run into some performance issues as the number of math segments increase on a single page. Paperman seems to be using something called MathQuill[3], has anyone here tried using it on large amounts of LaTeX math? KaTeX[4] is another possible alternative, and certainly the best I've tried in terms of performance, although it's still a little lacking in terms of symbol support.
Whenever there are too many equations rendered with MathQuill in the Desmos Graphing Calculator (http://desmos.com), there are definite performance issues, but we're working on them! Definitely hoping to borrow some tricks from the very impressive KaTeX.
Full Disclosure: I have worked for Desmos, and I'm still the creator and maintainer for MathQuill.
Nice little project btw. - Online Latex is IMO a not yet solved problem, however others have a big head start and I imagine the whole thing gets complex very quickly - especially considering LaTex build times. If you want to offer the full functionality with all packages and everything, your service basically becomes a PaaS and you'll have to charge for access. Yet this is something that quite a few people could be interested in, since getting a LaTeX environment up and running is still quite a hassle today. The problem with the business model is that it's really hard to try to charge money to academia, especially for things that are basically non-essential, even if they improve productivity.
Btw. if you still want to go that route, I'd look into Docker. Basically you can give every paying user an isolated container where he's running his jobs. This has quite a few advantages:
- more secure, since processes are isolated.
- easily scalable, especially with their hipache router in front of it. Each process sees the same port internally, Docker manages the mapping from global ports to local ones, hipache manages failover / load balancing.
- easy to separate into base functionality / pro packages for your business model - have a base image and an extended one with all the packages.
SageMathCloud (https://cloud.sagemath.com) provides a LaTeX editor "with all packages and everything", coupled with a full Linux shell, 5GB disk space, and 100% customizable compilation process.
"you'll have to charge for access" -- I do not charge for access, though the whole site does cost a lot behind the scenes; it's just that you're not the one who has to pay (Disclaimer: I'm the founder.) Anyway, I hope you'll try it out and complain (email me at wstein@uw.edu and I can upgrade quotas on your project).
Also, SageMathCloud and IPython notebook both have similar functionality to the original posts site embedded in them. For example, here is the example of the OP but as a (public) Sage worksheet:
In SageMathCloud worksheets, when you render %md cells, it is done entirely client side (no roundtrip to server at all), so very fast. I'm not sure about IPython notebooks.
> getting a LaTeX environment up and running is still quite a hassle today
People often say that. I find that assertion puzzling. I use LaTeX for hours everyday, so I think I exercise a lot of the functionality, but to install I just follow the brief directions on the TeX Live site (I don't use MiKTeX but I understand it to also install smoothly). Could I ask what part of the installation gives trouble?
When it comes to LaTex I decide the environment (OS / LaTeX distro) by which editor is supported. So far I still find 'Kile' the best editor by far. Which is why I have a Kubuntu VM just for that purpose. For the templates that I use there's a whole host of packages that I need - and the package names of course don't match in apt-get and in LaTex, so it basically becomes a 'guess what error message means which package is missing / try to google for all that' until everything runs. I don't know about you, but I don't call that smooth.
Personally, I just get everything. That is, I'd get the whole MacTeX distribution. Never need to worry too much then. (At least on Ubuntu, the stuff from apt-get is often years old, which doesn't matter sometimes, but does matter often enough to be annoying, in my experience.)
FWIW I like texworks and texstudio for "Visual" editing due to the side-by-side display of LaTeX and PDF (and using SyncTeX to jump between them).
Other than that I mostly use Vim to edit LaTeX.
I think texstudio is fairly similar to Kile you might want to give it a shot.
The biggest problem I usually have (on a Mac) isn't so much that it's difficult; it's that the MacTeX package is 2.4 GB, which often means an hour or so of waiting before I can actually do anything.
You can also add a few template document files, and maybe ads at the bottom to make some money off it because it can take off and your server may get a good hammering.
I wrote a kind of markdown to latex script to help me writing my thesis, based in previous versions of md2html.awk. It had some more features than Paperman, such as ((footnotes)), [[bib references]] and [(references to labels)]. It also supported several heading levels, an abstract at the beginning, and even had some support for images and tables.
It was never publicly released because, since it was for my personal use, required a serious amount of work to make it usable for more people and better (or at least some) documentation. Anyway, if somebody is interested, I have no problem sharing it.
Pandoc does look cool- I will have to try it. I wonder which input format is the most useful (has the best balance of features and ease of use) for it. For example, can I use markdown if I need references?
I wrote a preprocessor for plain TeX for chip documentation. You type 'make view' in your documentation source directory to convert text into pdf and view it with acrobat. It was interesting to write this to see how to make a full "style" for TeX.
The input is somewhat like markdown in that all ASCII characters print as is except \. Use \\ to print \, otherwise it's TeX: "see table \ref{tag} on page \pageref{tag}."
It supports math in that you can calculate derived table entries:
'D' means get the value from the cell below. 'DR' means get the value from the cell down and to the right. Also you can assign to and use variables in any order \{a*2} prints 20 because later I set \{a=10}.
pandoc can do footnotes `[^1]` and citations `@citekey` but not internal references (like \ref{fig:blag} in latex). This is a problem for academic writing.
I'm determined to write my thesis in markdown and recently wrote a pandoc filter that implements internal references using `#fig:blah`, with an `\autoref` like implementation. It works for figures, sections and equations and for html and latex output.
I started using Latex with editors like this (sharelatex I think), but eventually, when my advisor said "latex is source code," I came to the realization that I should be writing in my text editor.
Now I do all latex writing in sublime or vim and have a build script to compile to Pdf and open it in Preview on the left side of my screen. Save, build, review. Just as fast as an online editor, no lockin, and a native feeling.
If you want authors to actually write (scientific) papers in this editor you'll need a lot more:
* including figures, with captions
* tabels, with captions
* sections
* Something like the \ref{} command to refer to tables, figures, sections.
* Citations
Those interested in a tool that lets you use your text editor with an auto-refreshed HTML view should check out Softcover (http://softcover.io/), which among other things is the build system used by the Ruby on Rails Tutorial.
Nice project. Are the source available ? It would be nice to use but I'd rather host/use it locally.
Besides I don't know which font (Symbola?) you use in the .pdf but it appears ugly (part of the 'o' is missing and it is overall not too easy to read) on my laptop running Ubuntu 14.10.
The tagline is misleading. This is just a markdown editor with something like MathJax dropped in to do LaTeX-like equation rendering. Nevertheless, the live-editing and download PDF features are pretty cool. Nice work!
Nice demo. Hopefully the time will come when we will finally have a proper Latex editor that is easy to use and has an editor that makes it a joy to write with (think of iA Writer)
Can you elaborate? Most editors have SyncTeX (http://mactex-wiki.tug.org/wiki/index.php/SyncTeX) support and most viewers can handle that. You can pretty easily build on every change. Also, when the document becomes long, you can split it in multiple parts that only get rebuilt if they change. That's a sane way of organizing things anyways.
It's not any easier. You are just more used to Markdown and I'm assuming more practiced in it. I'm a lot faster in LaTeX than Markdown because I use LaTeX every day but only touch Markdown about once a month.
I would say "Markdown editor with latex inline equations" instead of calling this a latex editor - the most basic latex syntax doesn't seem to work!
(also: Isn't $$ an out-of-line equation, rather than a \displaystyle-sized inline)
