Not working on WSL

[peterlobster]

This plugin isn't working with my instance of Debian (which is really Pengwin, which is Debian, plus a few extra WSL things) on WSL.

What's going on is that I can't really install anything cause $ asdf list all flutter isn't producing any output. Originally, jq was having a permission error because wasn't it allowed to execute (although it's set to here), but I fixed that with chmod 755 ..., but I still get no output from $ asdf list all flutter.

Also, when I try $ asdf install flutter latest, I get back flutter is already installed. When I run $ asdf latest flutter, I get nothing back.

$ uname -m
x86_64
$ uname -s
Linux

So the problem is jq...

$ ~/.asdf/plugins/flutter/bin/jq
Segmentation fault

I noticed that in asdf-flutter/bin/jq-downloader, it pulls from https://github.com/stedolan/jq/releases/, which looks like hasn't been issued a new release in some time (despite a lot of new work that has already been committed). I also noticed that it was possible the segmentation fault error appeared to related to gcc 6, so I thought maybe I just need to get a fresh copy of jq.

So what I did to fix this is I installed jq via Linuxbrew (Homebrew has a reputation for staying fairly current), and then I changed this line in asdf-flutter/bin/list-all (and likewise, I changed the same line in asdf-flutter/bin/install) to jq="$(brew --prefix jq)/jq. Now, everything appears functional.

Now, this is not a very good long-term or elegant solution, as this fix really only works if you install jq with brew; but perhaps, it could be changed so that adsf-flutter trys to detect if you have jq pre-installed, before falling back on the old releases?

Thank you for the feedback. I will look into this and try to find a solution.

@oae Couldn't we wrap the installer script in something like this?

if local_jq="$(type -p "$jq")" || [[ -x $local_jq ]]; then
  echo "jq is already installed"
else
  # Install jq
fi

Still doesn't really address the old releases on GitHub though. Maybe we should build our own jq package to ensure compatibility? That's the only real solution I can think of...unless we can source a more recent version of jq. I think brew compiles their packages and keeps them on Bintray, or at least they used to. I think they've been moving them to GitHub or at least, away from Bintray, I think.

It seems like the scope of the new version for jq is too big. They are discussing it in jqlang/jq#2305. Building it from the source would add many dependencies to the plugin. Also, I checked the homebrew formula. It seems like only the mac version has the binary.

I could switch to fx. But I need to check its functionality before the switch.

@oae Oh, I didn't see that. I do know brew has a bottle though for x86_64_linux though. However, I still don't like the idea of being dependant on a 3rd-party package manager.

I think finding a better alternative of jq sounds appealing. Hopefully fx works out.

@oae Just a realization I had, asdf can only really be installed via Homebrew and git on Linux, so I guess installing jq via brew isn't the worst idea...especially if you already installed asdf via brew. 😁 #JustSaying

I implemented as you said instead of using fx. It will now use system jq if exists.
