poetry.bash-completion has multiple syntax errors

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).
OS version and name: macOS 10.14.6 Mojave
Poetry version: Poetry (version 1.2.0a2)

Issue

Generated a completion file for bash via poetry completions bash > /usr/local/etc/profile.d/poetry.bash-completion due to poetry completions bash > /etc/bash_completion.d/poetry.bash-completion not having the /etc/bash_completion.d directory on Mac. Sourced in .bashrc and wound up with a bunch of syntax errors that I had to comment out (i.e., not use.)

Attached the generated completion file with commented out lines.

Hi,

Can you add the version of bash you are using and how you installed Poetry and bash ?

I have tested your file with bash 5.1.8 on High Sierra and it worked properly.

bash was installed via brew and poetry is pip.

$ bash --version
GNU bash, version 5.0.11(1)-release (x86_64-apple-darwin18.6.0)
Copyright (C) 2019 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

This is free software; you are free to change and redistribute it.

 $ pip list
Package            Version
------------------ ---------
...
poetry             1.2.0a2
poetry-core        1.1.0a6

Updated bash to 5.1.8(1)-release. Re-ran the completion command and get this:

$ source ~/.bashrc
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: syntax error near unexpected token `clear'
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: `            (cache clear)'

Did you check the value of $BASH_VERSION ?
IIRC, it's used by bash completion to load its helper functions and if it's too old it won't but without a warning.
An mismatched value can happen for the following reason: your login shell is still configured to point on the macOS provided bash and your "Shell opens with" Terminal setting is set to "Default login shell".

You have two options here:

Change "Shell opens with" to point to your brew bash
Change the default shell used when you login keeping the "Shell opens with" default value

For number 2, you need to add your brew bash path to the list of available shells in /etc/shells (requires root access) and then use chsh -s <path/to/bash> as your current user.

Good catch with $BASH_VERSION. It was pointing to the old v3.x version of bash while the shell itself was up-to-date and the $PATH called the right one when checking the version 🤔

Set both the absolute path in iTerm (login shell to custom shell) to the brew bash and appending the same to /etc/shells, I'm now getting:

$ echo $BASH_VERSION
5.1.8(1)-release

Re-ran poetry completions bash > /usr/local/etc/profile.d/poetry.bash-completion, but no joy:

$ source ~/.bashrc
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: syntax error near unexpected token `clear'
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: `            (cache clear)'

From the looks of it, you did not install the bash-completion package.

Do that first and then put the poetry completion file under /usr/local/etc/bash_completion.d/.

This is what I've been doing:

$ poetry completions bash > /usr/local/etc/profile.d/poetry.bash-completion
$ ll /usr/local/etc/profile.d/poetry.bash-completion
-rw-r--r--  1 lance.stephens  admin   4.4K Oct  6 12:56 /usr/local/etc/profile.d/poetry.bash-completion
$ grep 'poetry.bash-completion' ~/.bashrc
. /usr/local/etc/profile.d/poetry.bash-completion
$ source ~/.bashrc
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: syntax error near unexpected token `clear'
-bash: /usr/local/etc/profile.d/poetry.bash-completion: line 40: `            (cache clear)'

Which appears to be supported according to poetry help completions.

I'm getting the same issue here on Ubuntu using the exact same commands and when i try to run it as a bash script normally. I have updated my bash and bash-completions to no avail.

The problem seems to be that completions for subcommands are written like

            (command subcommand)
            opts="${opts} ..."
            ;;

which isn't valid bash as far as i can tell. Separating the command and subcommand with a space doesn't seem to work.
But i'm no expert so take that with a grain of salt.

This only is a problem with 1.2.0a2 and doesn't exist in 1.1.0

I suspect this is an issue with cleo as we use it to handle the CLI ux, the issue seems to be how subcommands are being handled.

This one still fails accross all platforms.

$ poetry --version
Poetry (version 1.2.0b2dev0)
$ echo $BASH_VERSION
5.1.16(1)-release
$ poetry completions bash | bash
bash: line 40: syntax error near unexpected token `clear'
bash: line 40: `            (cache clear)'

The poetry maintainers are playing whack-a-mole with duplicate tickets. Poetry users will probably keep creating more issues for this bug as long as the bug still exists in the latest version of poetry, and an open issue for the bug doesn't exist. Hand-waving at an upstream repo and closing all of the issues makes it extremely difficult to follow what's going on.

Suggestion: leave 1 issue open for this bug in poetry and link it to the root cause issue in cleo.

Edit: This issue might be a good one to use, since it's linked to the cleo PR

I personally haven't looked at this issue for a minute (it merely lives in my 'common duplicates' doc) -- looks like it was closed by mistake as the Cleo PR should have specified Relates-To or similar. This shouldn't be closed in Poetry until after the Cleo release and subsequent bump of our constraint.

If anyone wants working bash completion for poetry now, I created a gist: https://gist.github.com/raffraffraff/36b7a8cd1a4308150d7f843724a19ff9

I wanted an excuse to learn the poetry syntax, plus having decent shell completion makes learning it much easier.

YMMV, but it's working great for me. It's able to complete commands, positional args and options, and even suggests package names, source names, config options and caches where appropriate (and I don't think the official shell completion will do that).

@raffraffraff

@raffraffraff without pull request it will be lost in the internet for sure. (I have fixed completions with vim+macros in <1 min).

@koutoftimer

@koutoftimer I didn't send a pull request because poetry uses cleo for bash completions, but my script is 'hand made'. I'm just sharing here in case it's useful to others.

This is well-known and universal; please refrain from "me too" as it only adds noise and distracts the people trying to get Cleo 1.0 over the finish line so we can ship the (already merged) fix 😄

Completion bugs are now fixed with the incoming release.

When is version 1.3.0 expected to be published?

When it's ready/the maintainers have had time to finalize the changelog (including any late merges).

If you go to the "watch" dropdown for this repository in the upper right corner of the page and click "custom", you can select to be notified of releases, which should send you an alert when 1.3.0 is published.

Just wanted to close the loop here (know the issue is closed haha) — running bash 5.2.15 and poetry 1.3.2 appears to have resolved the completion errors after re-exporting the completion script via

poetry completions bash > /usr/local/etc/profile.d/poetry.bash-completion

Appreciate everyone's help 🙏
