today in $DAYJOB, someone found the pycon 2016 talk, and we got to talking about how to use xonsh on old-ubuntu (py3.5) blades without shared logins/homedirs

Hi. Just tried to install xonsh 0.9.25 using both pipx and AppImage (this is in Linux btw). In both cases the reported version is wrong. In the AppImage it says 0.9.24.dev223 and in pipx it installs 0.9.24 for some reason.

using plain pip seems to work, but yet again the version doesn't look right: 0.9.25.dev3

also the official docs still point to 0.9.24 as latest version in changelog and in the readthedocs title

are these known issues?

in the AppImage version it says that last commit is: Commit Date | Jan 25 16:37:29 2021

I upgraded from 0.9.24 to 0.9.25 I now get this message on start

The xonsh.proc module has been deprecated in favor of the xonsh.procs subpackage. But I do not call that in my rc.xsh. Does this come from an xontrib and if so how do those upgrade?

I am trying to use xonsh as a shell during compilation and am somewhat confused by is it an interactive shell and what startup files it uses.

As far as I can see $XONSH_INTERACTIVE is correctly set

But if $XONSH_INTERACTIVE is False then no startup files are read whcih seems wrong - how do I set environment variables etc (as I my default shell is zsh - those variables were inherited) But this implies there is no point using xonsh here as I can't configure it

@bestlem

@jwlynch_gitlab I think a non-login xonsh shell (e.g. from a subprocess line like xonsh my_awsome_script.xsh) will not read the .xonshrc, whereas xonsh -l my_awsome_script.xsh will do so. However I haven't tested this explicitly.

Seems to be the same issue I see and my guess from the code is .xonshrc will not be read in either case - as a file is provided so XONS_INTERACTIVE is set to False and so rc not read

I'm trying to speed up my .xonshrc and I've discovered that adding aliases is substantially slower than I expected - nearly 4000 times slower than just adding items to a dict:

from timeit import timeit

def thousand_aliases():
    for i in range(1000):
        str = f'echo{i}'
        aliases[str] = 'echo'

def thousand_dict_entries():
    d = {}
    for i in range(1000):
        str = f'echo{i}'
        d[str] = 'echo'

timeit(thousand_aliases, number=1)
# 3.0883793910034
timeit(thousand_dict_entries, number=4000)
# 3.19940147199668

On my machine this is actually slow enough that my real list of aliases takes several seconds to apply. Is this known/expected behaviour?

:octocat: Hi folks! I want to remember you some points that help xonsh community:

if you have xonsh related projects on Github please add the xonsh or xontrib topics to the repository "About" settings. This allows to search your solutions using Github Topics: xonsh or xontrib.
if you have useful scripts written on xonsh in Github Gists the better way is to create repository with README for them that allows create issues and fork the code.
if you have the code on BitBucket or similar the better way to create empty repository on Github with README that contains the link on original repository and tag it like in point 1.
Finally take a look at promotion guide that written for xontribs but actual for any xonsh repository.

:octocat: Xanks!

Hey guys, haven’t find the answer for my question, so writing here. Is it possible to distinguish “set” in xonsh? In a sense that there is a pythonic data structure called “set” and bash command which deals with virtual variables.

It looks like an error in xonsh's parsing, as I'm no longer using the List type in the latest version of xlsd

Hi all!

I'm getting used to xonsh, just started playing w/ it last nite and had some questions about the .xonshrc file. Can I separate my .xonshrc file into multiple files and source them all in one location. it's getting a little hectic in here.

I was also wondering if there was syntax highlighting for sublime text?

@RitikShah You certainly can! Use the source builtin. I have in my .xonshrc something like this:

$MY_XONSHRC_ADDONS=g`~/.xonsh/*.xsh`
for f in $MY_XONSHRC_ADDONS:
    source @(f)

Is 'avox' not working right now, or is there some local reason I'm having issues?

Hi all, I have an annoying issue with xonsh and setting the screen width for subsequent commands via stty. See on StackOverflow "Why does stty cols 40 have different effects in the two shells bash and xonsh"). If anyone knows how to fix this, please answer. It has a bounty on it. 😄 Thanks!

Hello all, I've been tinkering around with my rc file and I wanted to add a toggle_python command.

Essentially, it would hide the prompt bar (which I think I can override the $PROMPT). It would also look at all of the python variables I declare (like via def or just variables) and delete them. I think I could do that via looking at locals() and then removing everything that's extra.

The thing is, I don't know if the event triggers for a python command or I'm wondering if this is even a decent idea haha. Thanks all
