@anki-code I'm super-interested in the same stuff: For debug printing of what actual commands a xonsh script executes, it would help a lot to know the python expressions in a subprocess mode line!

I made a small script to transfer the JSON history into the sqlite database, when switching to the sqlite history backend: https://gist.github.com/cryzed/dbb877ed814fc1c83bc3486d55235a1e

Hi! Good news, due to the awsome emacs-libvterm I finally might eb able to join the club of sophisticated prompt-toolkit users. :-)
Now I'm looking for keyboard shortcuts. I found the page in the doco, but surely there are more shortcuts (like <right> to accepts prompt-toolkits history suggestion). Are they listed somewhere?

Hey All! I would really love to get a release out today/this week, but I think we need to get xonsh/xonsh#3850 merged in first

I think I should implement the better warning for the deprecation as mentioned here xonsh/xonsh#3793

Happy to review PRs! :wink:

Happy to see you on board Anthony =)

@cafehaine

looks like my last patch accidentally removed the deprecation warning. welp.

I'm trying to determine in color_tools.py if xonsh is running with XONSH_SHOW_TRACEBACK, however after looking at print_exception in tools.py, I think it might be better to extract that code and put it in another function, something like should_show_traceback, and get_traceback_logfile

since it's quite lengthy and it might be useful outside of tools.py

Anthony Scopatz

@scopatz

tools is pretty close to the bottom of the stack, but another function is always welcome!

@salotz

is there anything like a subshell in xonsh?

I do this in bash/sh:

(cd $DIR &&
 wget $url &&
  unzip $filename)

But as far as syntax why do you need the line continuation inside braces for this kind of thing?

(echo "hello" and \
     echo "there")

without the \ I get a syntax error

Anthony Scopatz

@scopatz

You could try something like xonsh -c! echo "hello"

If anyone on @xore is available, I'd love a review on xonsh/xonsh#3850 in order to get the next release out. Thanks!

@wendellwt

good for 0.9.23! Q: can I change the behavior of existing tab-completers? Or to get something slightly different, do I need to write my own completer function? I would like argument-completion to look in the current directory first, but current completers don't seem to do that.

:new: New xontrib-sh - paste and run sh-compatible (bash/zsh/fish) commands in xonsh. Just start with ! and paste the commands to execute. The shell (bash/zsh/fish) will be found automatically.

:tada:!

@abingham

When I use xontrib load vox_tabcomplete I trigger an assertion ("/usr/local/Cellar/xonsh/0.9.23/libexec/lib/python3.9/site-packages/xonsh/parsers/base.py", line 2215, in apply_trailers assert False). Any idea what's going on?

hi all, is there a way to capture the command result , i has a cmd build with python mode like : cmd = 'ssh user@sshserver.com cat ~/myfile' , then i want to capture the result the cmd returns , but if i ran ``` result = $(@(cmd)) i got command not found

Anthony Scopatz

@scopatz

@eggcaker - in that example, cmd should be a list of str.

cmd = 'ssh user@sshserver.com cat ~/myfile'.split()
$(@(cmd))

should work

eggcaker

@eggcaker

@scopatz how about pipeline ?

Anthony Scopatz

@scopatz

I think it would have to be something like $(@(cmd1) | @(cmd2))

eggcaker

@eggcaker

mean , I cannot include the "|" inside the cmd

Anthony Scopatz

@scopatz

That's right. The pipe joins commands

eggcaker

@eggcaker

like : cmd = '.... myfile | rg my_search'.split()?

Anthony Scopatz

@scopatz

At least, that is how it is implemented now

You could use execx or similar to execute a block of code, but that wouldn't capture in the way that you want

hmmm actually

You might be able to create an ExecAlias out of the command, and then capture the alias

This is little hacky but it would look something like:

aliases['__my_piped_cmd__'] = '.... myfile | rg my_search'
$(__my_piped_cmd__)

I haven't tried that, but it might work

eggcaker

@eggcaker

yes , i known that way, it's works well, this time i just write some script quickly just want concat the command generate with python loop and run that command capture the result

David Strobach

@laloch

The following forks for me:

$ cmd = "cat ~/.xonshrc | grep '^$.*='"
$ execx(f"cmdout=$({cmd})", glbs=globals())
$ echo @(cmdout)

eggcaker

@eggcaker

Thanks @laloch this way works

eggcaker

@eggcaker

with $(@(cmd1) | @(cmd2)) seems not working

wait .. maybe not ...

eggcaker

@eggcaker

@scopatz $(@(cmd1) | @(cmd2)) works too ,my bad thanks @scopatz @laloch

Anthony Scopatz

@scopatz

cool thanks!

@matrixbot

Phase Hi, I would like to give a try to xonsh... would you have a website, wiki, sort of knowledge base with those kind of tricks? It looks feasible but strange for someone with a bash background :)

David Strobach

@laloch

Yeah, there's https://xon.sh with quite a lot of documentation at https://xon.sh/contents.html#guides.
