Fish completions raise errors but still works

[AxZxP]

• 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).

• macOS 10.15.7:
• 1.2.0b2:
• fish 3.5:

Issue

I installed the completions as explained in the doc, and completions are working. But there is an error when triggering autocomplete with TAB key :

~/.config/fish/completions/poetry.fish (line 57):
complete -c poetry -f -n '__fish_poetry_e3d63c4129b80bf7_complete_no_subcommand' -a source show -d 'Show information about sources configured for the project.'
^
from sourcing file ~/.config/fish/completions/poetry.fish

I put the last error only, but the console print this error for almost every line of this file.

Screencast if needed

poetry-fish-completions.mp4

[jfroy]

The -a flag takes a single string argument. The completions emitted by poetry need to quote the argument to -a.

For example, -a "source show".

[Secrus]

This is known and I am working on fixing completions in cleo right now.

[neersighted]

Please feel free to open a Cleo bug and link back here.

Summary

The problem still exists, but it only occurs when Poetry autocompletion is activated for the first time.

Environments

Steps to reproduce

---

How should I fix this problem? Shall I upgrade poetry to a preview version? Or just simply edit
and fix ~/.config/fish/completions/poetry.fish as follows on our own?

The Cleo release has not made it into Poetry yet -- @Secrus is working on getting a release out this week. Due to neglect/bit rot, Cleo is in a pretty rough state release-wise and is difficult to release. The hope is to reset the board here (and there has been a lot of work to that end) so Cleo can release early and often with Poetry's needs.

[Dragon1573]

Now I get it. I'll try to edit ~/.config/fish/completions/poetry.fish as a walkaround.

After the patch is released in Cleo and applied to Poetry, I should remove my own poetry.fish and re-generate one for an "official fix"?

If everything goes according to our plan, update for Cleo should be a part of next minor release of Poetry (1.3 at the moment of writing this). The info will be in the release notes for sure and it will state the need for re-generation of completion files

[neersighted]

Damn, closed by mistake as well.

[Secrus]

Completion bugs are now fixed with the incoming release.

+1, same issue (and same log) with Poetry 1.3.1 and Fish 3.5.1

[garbelini]

The last fix introduced a new issue but now it's too much quoting.

As a workaround search the the output for instances like '__fish_seen_subcommand_from 'self add'' and remove the extra quotes '__fish_seen_subcommand_from self add

Seems to work for me

[Dragon1573]

The last fix introduced a new issue but now it's too much quoting.

@garbelini Nice friend! Thank you for you solution. It also works for me.

I'm currently using NeoVim as my editor. I used the following command to quickly replace all these extra-quoted commands. It may also valid in Vim.

[qbedard]

Yep. Poetry 1.3.2 and Fish 3.6.0 here and seeing the same issue.

[dancju]

I edited ~/.config/fish/completions/poetry.fish and sorted out mismatched single and double quotes. Now this issue is gone.

• Fish 3.6.0
• Python 3.11
• Poetry 1.3.2

[Secrus]

The issue is now reopened. Please refrain from "me too" type of comments.

[drin]

since I haven't actually done the fix, I can share some specific things I've looked at.

completions_command.py#L231-L233 seems like it should be sanitizing a string correctly for substitution on line 258.

The regex provided by @Dragon1573 makes it seem like line 258 is the clear culprit of output strings being generated incorrectly.

The test file also seems like it should be correct: completion/fixtures/fish.txt#L40

so, I'm not actually sure what change to make.

Edit: removed source since it's not relevant (see comments below)

[vkravets]

At Fish 3.6.0 at complete there is no option -A

from 2.5b1

complete no longer recognises --authoritative and --unauthoritative options, and they are marked as obsolete.

[oliverandrich]

It is still a problem with Poetry 1.4.0 and fish 3.6.0. The problem seems to be that the quoting for the complex commands like "self update" is mangled. I could fix the problem by removing all these quotes around "self update", "self add", ...

[drin]

It is still a problem with Poetry 1.4.0 and fish 3.6.0.

I believe poetry 1.4.0 still uses cleo 2.0.1, see my above comment.

the 1.4 branch still has cleo 2.0.1 in its poetry.lock file

[drin]

I'll try to request that cleo get a new release, I'm not sure what the process is for it so I just asked in the discord for now. Will update this comment as appropriate.

[oliverandrich]

Thanks, @drin. I installed a fixed version of the fish completion file in my user config and wait for the update to come.

[drin]

btw when I asked last week, the response was that cleo maintainers have some bugs they want to fix before they release. I do not know what the bugs are, so I guess there's not much to do.

[phsb5321]

Hey, is there any updates related to this issue ?

[MalayAgr]

Still facing this issue. Any updates and/or solutions?

[drin]

I don't think this issue needs any more updates.

After the next cleo release it will be fixed and otherwise there are a variety of suggestions in the comments for short-term workarounds.

You can check in the poetry discord to see if there's anything you can do to help with release

[sersorrel]

the conversation alluded to above:

since then there have been essentially no messages in the #cleo channel.

in 2022, there was a post stating that "Cleo was quite neglected for some time, we are now getting it back in shape"; it's unfortunate that this doesn't seem to have had any user-visible impact

[Secrus]

It takes time, to do things right. At the moment, I am the only person actively working on Cleo maintenance. Everybody on the Poetry team is working on this project as a volunteer, giving it as much of our free time as we can. I understand the frustration when things don't work as intended, but please have patience.

[rahul286]

On macOS, the following appears to be working for me.

sed -i.bak -E "s/'([a-z]*[[:blank:]][a-z]*)''/\1'/g" /opt/homebrew/share/fish/vendor_completions.d/poetry.fish

Please note that I use GNU sed (can be installed using brew install gnu-sed. if you do this, read post-install caveats)

[samof76]

@rahul286 thanks

Its worked for me on linux as well...

[iRomanyshyn]

Hi! The issue is still there.

[Larandar]

For my fellow sd users the following work and is easier:

poetry completions | sd "'([^']+)''" '"$1"\'' > ~/.config/fish/completions/poetry.fish

Contrary to what some earlier regex were looking for, the only problem is double quoting in the same argument ('[^']+'')

@Asseel-Naji Sadly this does not work under fish, version 3.6.1. Care to share your working setup?

Here is what I tried:

1. Tried poetry env info --e[TAB] and it did not complete.

2. Tried inverting the quotes (double to single and vice versa - as seen below), but it does not work either.

   complete -c poetry -A -n "__fish_seen_subcommand_from 'env info'" -l executable -d 'Only display the environment\'s python executable path.'

3. Tried using without the any quotes (as seen below), and it did the autocomplete.
   HOWEVER, that way poetry env use --e[TAB] also completes to --executable which is wrong (the option does not exist).

   complete -c poetry -A -n '__fish_seen_subcommand_from env info' -l executable -d 'Only display the environment\'s python executable path.'

After some digging, it seems to me that the fish-shell/fish-shell#7107 issue is tackling a similar problem (nested subcommand and option parsing), might be worth looking into once it's resolved.

[Asseel-Naji]

1. Tried poetry env info --e[TAB] and it did not complete.

I just tried the same, poetry env info can only be followed by :

--ansi                                                                                      (Force ANSI output.)
--directory          (The working directory for the Poetry command (defaults to the current working directory).)
--help         (Display help for the given command. When no command is given display help for the list command.)
--no-ansi                                                                                 (Disable ANSI output.)
--no-cache                                                                      (Disables Poetry source caches.)
--no-interaction                                                          (Do not ask any interactive question.)
--no-plugins                                                                                 (Disables plugins.)
--quiet                                                                             (Do not output any message.)
--verbose  (Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug.)
--version                                                                    (Display this application version.)

That's said, if it's indeed doesn't work on intended command. Could you make sure the content of the file are pasted in ~/.config/fish/completions/poetry.fish and after that restart fish.

[mrmeszaros]

Did all that - same results.

Let me explain my issue: here is the help page for poetry env info

$ poetry env info --help

Description:
  Displays information about the current environment.

Usage:
  env info [options]

  -v|vv|vvv, --verbose       Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug.

As You can see the help page clearly notes the -e, --executable option.
The completions script - as You also see on Your system - fails to provide that option when asking for completions.

However I see that the subcommand specific options might not be in the scope of this issue, and might need a separate one.

It takes time, to do things right. At the moment, I am the only person actively working on Cleo maintenance.

@Secrus I know it takes time, but just share the list of issues you want addressed before cutting a release of cleo and I suspect people will help. You don't even have to document them, just list them and see if we can do the rest. Or perhaps just let us know how you'd like us to cherry-pick the commit and cut a new release and we can move on.

It's one thing for there to be enhancements or bug fixes you want to get around to, but this issue requires manual intervention everytime there's an update and the amount of work required for someone to help seems trivial. I'm not sure why this has to drag on any longer than it has.

Edit: oh, actually maybe this milestone is what you want to have complete before the next release?

@mrmeszaros I agree that would be a separate issue, since this one was just focused on the errors/warnings produced by quoting errors. I'm not sure if a related issue already exists, though.

@Asseel-Naji Sadly this does not work under fish, version 3.6.1. Care to share your working setup?

Here is what I tried:

1. Tried poetry env info --e[TAB] and it did not complete.
2. Tried inverting the quotes (double to single and vice versa - as seen below), but it does not work either.

   complete -c poetry -A -n "__fish_seen_subcommand_from 'env info'" -l executable -d 'Only display the environment\'s python executable path.'

3. Tried using without the any quotes (as seen below), and it did the autocomplete.
   HOWEVER, that way poetry env use --e[TAB] also completes to --executable which is wrong (the option does not exist).

   complete -c poetry -A -n '__fish_seen_subcommand_from env info' -l executable -d 'Only display the environment\'s python executable path.'

After some digging, it seems to me that the fish-shell/fish-shell#7107 issue is tackling a similar problem (nested subcommand and option parsing), might be worth looking into once it's resolved.

Could it be that

without \' for 'List Poetry\'s caches.'

that the backslash is actually not working?
