This is cool. I wanted to do a blog post on some real estate appraisal topics, which requires math examples. Is this open source? Where I can I find socrates.io - it goes straight to the interface.

ianstormtaylor4• 13 years ago

Yup it is! On Github: https://github.com/segmentio/socrates

LOVE it!

People in this thread may also find GmailTex useful. It's a browser plugin which enables using LaTeX syntax in Gmail and GChat.

P.S.: This Socrates thing is pretty fantastic. Is there a keyboard shortcut for switching to the compiled view?

If you think this is cool, check out http://spandex.io/

kanatzidis• 13 years ago

Oh man, this is really cool. Great job. I'm the co-founder of http://SpanDeX.io (which I see someone already commented about) and we love seeing this kind of stuff. Great to see LaTeX getting implemented in a really useful way!

imslavko• 13 years ago

That's cool. I was using markable.in in last weeks. But lack of code highlighting and Mathjax brings socrates.io on the first place :)

this looks nice, but i'm confused.. how do i actually use it on my webpage?

traeblain• 13 years ago

This is great!!

Why not use jqMath? It's latex based, 10 times smaller, and 10 times faster than MathJax - which is aimed more at publishers.

jey• 13 years ago

Interesting. Looks like it maps TeX directly to HTML, so it must support fewer constructs? Or what are the downsides? Being 10x faster and 10x smaller without any drawbacks seems too good to be true.

jessriedel2• 13 years ago

"TeX-based" is the operative term here. The syntax is somewhat different true TeX (so it would drive people who use TeX regularly crazy, like me). And I don't believe it has the same abilities.

jqMath doesn’t use LaTeX.

I recommend upgrading to the latest release of marked ( https://github.com/chjj/marked/tree/v0.2.8 ). It has a few improvements as well as GFM tables.

ianstormtaylor4• 13 years ago

Beautiful! You wouldn't happen to know if it supports "smart" quotes would you? Been meaning to find one that does support those.

Also auto-id-ing heading elements so they can be hash-linked to? That's another of my marked requests.

> Beautiful! You wouldn't happen to know if it supports "smart" quotes would you?

Marked has a pretty big todo list right now. Those are on it somewhere.

> Also auto-id-ing heading elements so they can be hash-linked to?

This is actually requested less than I expected it to be, but I think I do want to add something for it in the future.

Really wish they used Pandoc Markdown or some other form of extended Markdown... then I could consider using it for real stuff,

csense• 13 years ago

I tested it on Chromium (the FOSS version of Google Chrome), and in that browser, the math uses a much smaller font than the Firefox version. (Firefox looks "right.")

I'm using Linux Mint 14 (the most recent version), the default version of Chromium from the distribution's repo; all packages are up-to-date, and I don't have any browser extensions or any intense customization.

Benferhat• 13 years ago

Same here with Chromium (23.0.1271.97-0ubuntu0.12.04.1)

warmfuzzykitten2• 13 years ago

Looks fine in Chrome / Mac OS X.

indubitably• 13 years ago

The Firefox version appears broken to me?

There used to be a similar service at http://notepag.es/ However, it seems to be down now.

swah• 13 years ago

In the end, how should I use this product? Writing Latex before compiling the final thing on your PC?

justinvh• 13 years ago

I wrote a LaTeX Markdown plugin as well, but it served a different purpose. It was geared for offline documents.

https://github.com/justinvh/Markdown-LaTeX

It generates inline/base64-encoded images with a small file-cache for the generated images. Try it out!

hyperbovine• 13 years ago

I wish it had better support for live editing, but this is really a limitation of MathJax / TeX in general. Still, I wonder if it might be possible to improve the experience a bit by e.g. only updating when I close a $$ block, etc.

mcmire• 13 years ago

That's what I was going to say. I found the constant reformatting of the math stuff in the right pane extremely jarring.

Otherwise, nice and simple.

pkrein• 13 years ago

yeah -- we'll try to smooth this out!

gmt2027• 13 years ago

It's a shame that there doesn't seem to be any export option.

ianstormtaylor4• 13 years ago

That's something we've gotten a lot of requests for and want to build one of these weekends :)

warmfuzzykitten2• 13 years ago

Does this mean you can only see the math in Socrates? How do you publish a page on the web outside Socrates?

quaz3l• 13 years ago

I've been working on something just like this! It is a mashup of Ghost<john.onolan.org/ghost/>, and a editor like this. If you was to see the uncompleted version its here: http://quaz3l.github.com/ghost/g-admin/posts.html
