Cannot load .juliahistory

[vspinu]

Sorry for being late on this. Github stopped sending notifications to us. Can you still reproduce that?

What is the error for makeinfo?

[vspinu]

yeh, by the way. You should first check if julia works in shell buffer. That is, M-x shell and then julia-release-basic (not julia!!). If that works, ESS should work as well.

Hi,

Just to say I have the same issue with ESS freezing on Windows at the same point. I can quit with C-g to unfreeze Emacs and the julia buffer is running, however when I try to use the help command C-c C-v I get the following error:

ess-error: ESS process not ready. Finish your command before trying again.

Both the initial loading and help function work fine on my OSX laptop.

I got the same behavior as the previous commenter with Emacs 24.3 and ESS 13.09 on Windows 7 x64.

[vspinu]

But can you execute commands in julia? That is, are you sure julia is really running? Do you see the spinner in the modeline what indicates that the process is busy?

What is the julia prompt on Windows?

[jfsantos]

Yes, Julia is running. I can switch to the julia buffer and call commands if I use C-g to unfreeze emacs. The prompt that shows up on Emacs is "invisible", i.e., it does not show anything but the results to my commands (there is no "splash" as in Linux).

[vspinu]

That is the likely reason. Prompt is important. If there is no prompt, there will be no way to know when the command is finished. Is there at least a space after the new line?

In linux prompt is julia>. I am really surprised it is different on windows. Are you sure? Can you please run it in terminal and paste here a couple of results?

[jfsantos]

In fact the prompt for the julia-basic.exe binary is "julia>" and the default header appears as usual (when calling it from outside emacs). However, whenever I run any commands, it seems to add an extra new line to the result:

julia> a = 1
1

julia> (empty prompt line that appears automatically)
julia> | (cursor is here)

That extra prompt line appears automatically. This is what I get at the julia emacs buffer when trying to run something similiar:

a = 1
1
?zeros
ERROR: syntax: extra token "zeros" after end of expression
WARNING: backtraces on your platform are often misleading or partially incorrect

x = zeros(3,1)
3x1 Array{Float64,2}:
 0.0
 0.0
 0.0

Please let me know if there's anything I can do (either from inside Emacs or with the Julia binaries on Windows) to further investigate this issue.

[vspinu]

All right. It is probaby some interaction with emacs. Please open a shell buffer M-x shell. And call open julia-basic from there. See if it works. If you can run it from shell there is no reason it should not work from ESS.

[jfsantos]

Behavior straight from a shell is the same as I reported previously. There is no "splash" and no prompt. Calling julia-basic from Windows' "cmd" works as expected (except for that extra empty prompt line).

[vspinu]

Thanks. This is a julia issue then. Would be nice if you could report
this to julia folks. They will know much better what is going on.

In the beginning there were some issue with emacs terminal under linux
as well and they sorted that out.

[jfsantos]

Thanks for helping with sorting this out. I'll report this to their side to see if we can figure out how to solve the issue with julia-basic.

Was this problem ever resolved? I am experiencing the same issue.

[mmaechler]

which issue ? The title of this issue is about .juliahistory .. and I think that has been solved long ago, and for that reason this issue has been closed long ago. Please open a new issue... or talk on the [email protected] mailing list.

[simonp0420]

Sorry about being ambiguous. I was referring to the issue discussed by @jfsantos, where there is no prompt when running Julia under Windows 7 ESS. I looked at the Julia mailing lists and issues, but found no references to this problem. I thought that perhaps @jfsantos had worked out a solution and therefore did not bring it up on the Julia issue tracker, as he said he would.
