That's true, that use case never happened. Would you be so kind to open an issue in the github repo? :smile:

@Peaker
hard on the phone, tomorrow I'll try to remember :)
Nick Tchayka
@NickSeagull
Thanks! Anyways, the thing is that. Just create an empty folder and open it, Haskell.do will initialize everything. Take into account that it adds some dependencies for plotting and rendering code, that's why its done that way ^_^
Eyal Lotem
@Peaker
so no using it on an existing haskell project?
Nick Tchayka
@NickSeagull
Right now it is not supported, as we use a custom GHC preprocessor, but it is planned to change in the future theam/haskell-do#121
Eyal Lotem
@Peaker
maybe initial start of Haskell do should create an empty project in some default location so there are no barriers to starting experimenting?
(a barrier I failed to pass!)
Nick Tchayka
@NickSeagull
hmm, that is very interesting! :D
Something like a "playground"
Just created those 2 issues @Peaker thanks!
Eyal Lotem
@Peaker
sure thing :) curious to try it tomorrow

@eschnett
how do i use latex in a document? this "$x$" doesn't work; it just outputs the "$$" signs. is there an example? Nick Tchayka @NickSeagull Hello @eschnett , welcome to our Gitter channel :) Theorically, this $$ L_{dB}(t) = \frac{\sum_{k=1}{N}E_k}{N} $$ should output a nice equation Erik Schnetter @eschnett no, this just outputs the source of the equation. this is macos with safari. i'm using mathjax just fine on other sites, if that's what you're using internally. Nick Tchayka @NickSeagull Do you happen to have Google chrome installed @eschnett ? Erik Schnetter @eschnett i do. same problem with chrome and firefox. Nick Tchayka @NickSeagull Hmm, that is strange, doesnt happen to me. Can you try to see if there are any errors on the developer console of the browser? Erik Schnetter @eschnett @NickSeagull i didn't see any errors, but i'm not familiar with the browser console so i may have looked at the wrong place. Nick Tchayka @NickSeagull To open the Chrome Console, press Cmd+Option+J. After that a console should appear, if any errors happen to have occured, they would look like this: @eschnett Erik Schnetter @eschnett @NickSeagull did that. no errors appear. Nick Tchayka @NickSeagull Weird... @eschnett what were the exact steps that youve taken to install Haskell.do? Also which version of OS do you have and which version of Haskell.do? Erik Schnetter @eschnett i downloaded and unzipped the macos zip file for version 0.9.5. this is macos 10.12.6 “sierra”. stack was installed previously via homebrew. i then created a new project via haskell.do, and am now editing the respective page. stack is installed via homebrew, not by using the instructions on your web page. Nick Tchayka @NickSeagull Yes, its okay, if it creates the proejct and everything correctly that is not the problem Erik Schnetter @eschnett which part of the system is supposed to transform the $$ latex to something nice-looking?
Nick Tchayka
@NickSeagull
As you said, we are using MathJax, so it should be MathJax
What happens if you run the line MathJax.Hub.Queue(["Typeset",MathJax.Hub,"outputDisplay"]); in the Chrome Console @eschnett ?
Erik Schnetter
@eschnett
this makes it work!
Nick Tchayka
@NickSeagull
Hmm
Lets try to do one thing:
1. Write another LaTeX expression
3. Press CMD+Return again to see if it works
Erik Schnetter
@eschnett
after 1 and 2 it went back to being bad
3 didn’t help either
sorry, gotta go now for the announcement at https://twitter.com/LIGO… will be back later. thanks for your help so foar!

@NickSeagull
Great! Thanks to you for giving this valuable feedback!
Good luck there :)

@NickSeagull if you have time you should consider submitting a paragraph or two on Haskell.do to the HCAR
the first deadline's closed now but Mihai gave all the authors 4 more days for proofreading the draft
Nick Tchayka
@NickSeagull
Great! Thanks @ocramz ! 😁

Hi all
I've started tinkering with the code, with a mind to write a miso-based frontend
but I have some doubts regarding the overall design and I figured this would be the place to discuss
so on one hand we have typical cabal/stack projects: multiple files in multiple directories, with dependencies forming a DAG
on the other, the notebook-style interaction: evaluate a cell, show results, evaluate another cell etc.
Marco Z
@ocramz
is the "cell view" just a split view of a single source file, and every time we modify one cell a stack build is issued? or something equivalent to a stack build --file-watch is constantly running?
