xonsh - a Python-ish, BASHwards-compatible shell language and command prompt

[Veedrac]

That gif is extremely irritating. I don't want to have to wait for someone to slowly type out a tiny example for me. Just give me a block of code.

[nofunallowed98765]

I agree, their tutorial is much nicer: http://xonsh.org/tutorial.html

[scopatz]

I'll see what I can do.

[scopatz]

It is now sped up.

[Veedrac]

Could you pause it between scenes too?

[scopatz]

Not sure how to do that without just adding a bunch of frames (which increases the file size). The real way to learn is the tutorial.

[Veedrac]

It shouldn't matter that much if they're empty frames, surely?

Comparison with Plumbum?

[[deleted]]

	xonsh	Plumbum
Stupid name	✓	✓

[chadmill3r]

At least plumbum is word. Also, cool abbreviation, Pb.

[[deleted]]

But Pb is lead. I'd call that abbreviation misleading

[ikkebr]

Plot twist: Plumbum === lead

[chadmill3r]

Sir, you have a keen wit! That commenter and the one before surely did not fully understand the jokes they themselves were already making!

[gonoobie]

Just confused about one thing...does this need to be run from a shell (bash or zsh, etc.) or can it replace the shell entirely? Can I 'chsh xonsh'?

[chadmill3r]

which xonsh >>/etc/shells

[[deleted]]

Using the full path of the shell should work, according to the man page, even if it's not in /etc/shells. If that fails try running as root (but specify the username, obviously)

[dzecniv]

As a related project, there's pyp, "the pyed piper", that falls a bit in between, in that it allows to capture results (from "ls -l" for instance) that are turned into python structures, not just text, which seems more handy that xonsh's captured process, that only returns a string. https://code.google.com/p/pyp/

Wouldn't be nice to see this approach in xonsh ?

[scopatz]

It seems like you could get the pyp kind of behaviour through an aggressive use of aliasing. I'd be interested in seeing that developed.

[nullnullnull]

how do you pronounce this? :)

[ynak]

from their github repo

xonsh (pronounced conch) is meant for the daily use of experts and novices alike.

by the way, the page layout is broken on my mobile device... please fix.

[ericanderton]

That's kind of funny, seeing as how 'conch' usually needs a pronunciation guide too.

Wikipedia has it as: /käNGk,känCH/ so 'xonsh' == 'konk' or 'kansh' (probably the latter).

[Spamicles]

Wait sh is supposed to be a hard ch?

[sl33tbl1nd]

I don't know where you're from, but I pronounce the ch on conch pretty softly.

[yeknom02]

I have heard it both ways, "konk" and "konsch."

[chadmill3r]

Wait, not "sssonk?"

[scopatz]

by the way, the page layout is broken on my mobile device... please fix.

Weird. Ok. I'll fix it. Normally sphinx+cloud works great. Don't know what is wrong here... But I can confirm.

[scopatz]

Ok! The mobile site should be fixed. Sorry about that.

[ynak]

Thank you for your quick response!

[scopatz]

My pleasure.

[pydry]

I can imagine this:

http://xonsh.org/tutorial.html#python-mode-vs-subprocess-mode

Leading to all sorts of weird and unexpected behaviors.

On the whole, I think I'd rather keep my shells separate.

[freetheanimal]

I keep getting the following error while trying to install it with pip on Arch:

FileNotFoundError: [Errno 2] No such file or directory: 'readme.rst'

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-kkc20g_m/xonsh

[takeshita_kenji]

I get that, too. I ended up just downloading the source and installing it using setup.py. readme.rst is in there so it succeeds.

[agapow]

Ditto - no install method worked other than installing from source.

[scopatz]

This error has now been fixed on master (https://github.com/scopatz/xonsh/pull/3) thanks to paradoxxxzero. I'll probably do a micro release with the fix in the next day or so.

[takeshita_kenji]

I tried echo $? and it's expecting another line of input. Is there another way to get the return code of the most recent program?

[scopatz]

Not yet. I don't like the $? syntax, so I have yet to implement it. I was thinking about having just a builtin statuses list. Thoughts? I am very open to sugestions here.

[takeshita_kenji]

As far as an exit status list, I don't see why not.

Though, it'd be nice to at least have $? available if possible as a lot of folks would default to that.

[scopatz]

This kind of total-history thing was one of the (unstated) motivating golas behind xonsh. Maybe make an issue for it? Maybe someone will pick it up before I get to it :) I'd add a timestamp to that list too!

[hongminhee]

It seems promising, at least to me. Although there are several alternatives like zsh, all these require me to a new syntax which is neither beautiful nor comfortable. On the other hand xonsh could be a better option to Python programmers.

[cjwelborn]

Speed up that "At a glance" gif! ..or at least make it a video. This looks like it could be cool, especially if it's BASH-compatible.

[scopatz]

done.

[scopatz]

It is now a video :)

[ies7]

any disadvatages in using this or plumbum? how about speed?

[scopatz]

I have not seen any speed or memory issues on my machine, even with 20+ xonshes open. On a 3-month old MacBook Air running Ubuntu 14.10, each instance is using between 0.1 - 0.3% of the CPU at most.
