Emacs with Julia

[Ben Ward]

Hi, 

Just used the readme to get julia working with emacs and ESS - but I'm wondering what I need to do with the julia mode script that's in the contrib folder of the julia directory - if anything, How have other people set this up? In addition, what do people recommend in terms of editors for julia? The only two I've seen mentioned are Emacs and JuliaStudio

Best,

Ben.

I think if you use ESS mode you do not want to use the julia-mode.el code in contrib. ESS mode has more features than julia-mode.el so it is a good way to go. I use emacs for all my coding and it works well.

Inside the contrib/ directory you'll find modes for multiple editors.

ESS has a version of julia-mode.el that is dervied from the version in
contrib -- so ignore the contrib/ version. Stephen

I'm using sublime text, which has a pretty good julia mode that I got through the package manager.

I'll chime in as well with a pitch for Sublime Text. I created a port of SublimeREPL which allows a Julia repl to run within sublime text 2. The package and install instructions are here: https://github.com/karbarcca/Sublime-Julia

I've got to try this out. Also, I just added Sublime Text to the list of supported editors.

I'm giving sublime text a go - looks good! The juliaREPL doesn't want to work though, even with my path set up for it according to the instructions (OSX):

"default_extend_env":{"PATH":"/Users/wardb/julia/usr/bin;{PATH}"},

I get a message saying `OSError(2, 'No such file or directory')` when I try to start julia under tools > SublimeREPL - Julia > Julia.

Best,

Ben.

There might be a few things going on here.

* The name of the file it's looking for is "julia-release-basic"; can you make sure that exists in your julia/usr/bin folder?

* You may try fiddling with the extend_env key-value: "default_extend_env":{"PATH":"{PATH}:/Users/wardb/julia/usr/bin"}

* Are you saving in the default package settings? Make sure to copy default package settings and paste into Preferences => Package Settings => SublimeREPL-Julia => Settings - User

* I've heard of some OSX file system case sensitivity issues lately, this is a maybe...

Hopefully some of these ideas help.

Hi,

It does not the like it if I put the line in as you say:

Error trying to parse settings: Unexpected trailing characters in ~/Library/Application Support/Sublime Text 2/Packages/User/SublimeREPLjulia.sublime-settings:6:22

But julia-release-basic does exist in the directory,

Best,

Ben.

Mind sharing what made it work for the greater community?

Relatedly, I just added a quick-and-dirty inferior Julia shell to julia-mode.el, since its something I use all the time with other dynamic languages. I know its also part of ESS but that is a huge package that does a million things I have no interest in and I like to keep my config as modular as possible. If anyone else wants this the relevant file is in my fork of Julia (https://github.com/porterjamesj/julia/blob/inferior-julia/contrib/julia-mode.el). I bind C-RET to send-line-or-region and C-shift-R to reload-buffer. Note that you have to set the path to your Julia executable, and it must be the non-readline version, as the readline one doesn't play well with comint-mode.

Best,
James

I messed about with the command a bit more and found that replacing the semi-colon I had in my path string with a colon made it work. Are there key bindings for the Julia specific repl like for SublimeREPL - I note it also does not seem to appear in the Command Pallette - or it does have an option REPL - Julia, but if you select it and press enter it does not start (I checked and others like REPL - Python and REPL - R do - and the Julia REPl does if I go to it through the menu's - just not the pallete).

Best,

Ben.
