xonsh is a Python-powered, cross-platform, Unix-gazing shell language and command prompt

prompt-toolkit/python-prompt-toolkit#1241 (you already mentioned this in a starship related discussion)

prompt-toolkit/python-prompt-toolkit#1271 this PR fixes this issue (and other completion menu related ones)

Strange probelm: When I interrupt an on the xonsh commandline long running for-loop (something like:

for f in open('filelist.txt'):
     grep -H "MySearchTerm" @(f.strip())

) with a SIGINT signal, then I get sometimes in the xonsh shell the error:

>$ RecursionError: maximum recursion depth exceeded in comparison

Any idea why?

Hey everyone, hope you’re well.

having a weird issue with Xonsh. Tried to write a little program to move files, and its failing with “name file is not defined”

files.txt in for filename in files.txt: is interpreted as a python variable and it isn't defined ineed

@alat-rights

oh gosh! That’s silly of me. Thanks for letting me know.

you can do something like
for filename in $(cat files.txt).split("\n"):

(strange issue, I can't see the attached image in my matrix client)

@anki-code

The best way is to use splitlines instead of split and stripping:

for filename in $(cat files.txt).splitlines():
    mv @(filename) misc/
    # OR explicitly:
    $[mv @(filename) misc/]

@alat-rights I recommend to read the xonsh cheatsheet - it's good start.

Ok one more question, do you guys know how I can get tmux to auto-start xonsh at startup?

Use default-shell not default-command as I found out the hard way.

Hi! How do I get standard shell utilities like "ls" and "cp" working in xonsh on windows?

4 replies

my first thought would be PowerShell -Command ls but that has a delay of about a second before it actually runs the command which would suck for regular use

and cmd /c dir gives you less information and a worse UI than the powershell version

halloleo

@halloleo

Is there a way to use the command mode globbing operator

g`...`

with Python expressions? Given my_path = 'data/*.csv' I tried

ls -l g`@(my_path)`

but this way it doesn't work.

Hi there! I'm trying out xonsh and I find that the reverse-i-search mode is not working as I expect: If I search for something and then press enter, on bash/zsh it will execute the selected command. Xonsh deletes the line yet does not execute the command and stays in the reverse-i-search mode. Another thing is that if I press the right/left arrow keys or end/home while in reverse-i-search mode, I expect to drop into the shell where I can edit the command, while xonsh moves the cursor in the reverse-i-search query. Would this be categorized as a bug or is this a change xonsh deliberately made?

Is there a git autocompletion engine for xonsh

setting both

Disabling either of them stops crashing. Even more: setting async, then running xonsh, then setting update on keypress makes it work fine too. Is this a well-known issue?

Anyone know how I can get xonsh to reload the prompt colors after changing $XONSH_COLOR_STYLE? Apparently not even reset is enough to get the new colors in the prompt, I have to start a completely new xonsh process. My plan is to make 2 aliases next-style and previous-style which cycle through all styles and take care of reapplying the colors. That works mostly, except for the prompt colors.

well, it works here

ah prompt colors, sorry

@cryzed: could you open a github issue? I might look at it later

dyuri

@dyuri:horak.hu

found a bug during investigation that if $XONSH_COLOR_STYLE is set to something invalid then xonsh can't start (got the fix already)

well, for me the colors of the prompt are also changing

hey is it just me or does if/else shorthand not work in xonsh?

oh nvm apparently the websites just don't make it clear how that shorthand works

I have a possibly silly question

I'm trying to do something like

    cmd = ['xclip', '-selection', 'clipboard', '-t', content_type]
    p = Popen(cmd, stdin=PIPE)
    p.communicate(content)

(after https://github.com/brandon-rhodes/homedir/blob/1878c32bb0546f8485b768cd8d8399f4c422e53e/.fvwm/z_transform.py) in xonsh and can not figure out how to pipe the contents of a variable into the stdin of a subprocess

I've been combing through the docs for xonsh and prompt-toolkit, as well as the source code, and haven't been able to figure this out: I would like to map the key sequence: ";;" to "escape" in ViInsertMode. I found where escape is defined in the prompt-toolkit code, but it doesn't seem to have a related function name like "event.current_buffer.open_in_editor". So I tried copying the code into my custom_keybindings() which causes a syntax error in unrelated lines. I expected more helpful errors.

@bindings.add(';', ';', filter=ViInsertMode())
def _back_to_navigation_mode(event):
      buffer = event.current_buffer
      vi_state = event.app.vi_state
     if vi_state.input_mode in (InputMode.INSERT, InputMode.REPLACE):
         buffer.cursor_position += buffer.document.get_cursor_left_position()
     vi_state.input_mode = InputMode.NAVIGATION
     if bool(buffer.selection_state):
         buffer.exit_selection()

The code I tried to adapt came from python-prompt-toolkit/prompt_toolkit/key_bindings/bindings/vi.py:421 I tried to see if I could make KEY_ALIASES work for this, but I obviously didn't understand it. Am I missing something obvious here?
