Add option to use locate to list repos

[cljoly]

• refactor: isolate picker creation
• feat: add cached_list
• fix: change prompt for the various commands

[cljoly]

There is a bug in the construction of the repository list (we get the .git, not the repo itself).

[molleweide]

on macos intel.

it seems that the list is not populated visually when using the cached command.

1. Can I runt cached_list the first time or do I have to rund regular list first to populate the cache?

[cljoly]

You should be able to run cached_list the first time. Have you populated the cache with sudo updatedb first though?

[cljoly]

Also, does locate -r '/.git$' return anything for you?

[cljoly]

I think I’ve fixed the issue with the trailing .git in entries (in 5ea1934).

Here is what I get with a freshly started neovim:

I hope the screencast helps to show the behavior I think you should get.

[molleweide]

returns command not found on macos

[molleweide]

returns on macos

locate -r '/.git$'
locate: illegal option -- r
usage: locate [-0Scims] [-l limit] [-d database] pattern ...

default database: `/var/db/locate.database' or $LOCATE_PATH

[molleweide]

BUT my terminal is a bit messed up at the moment tho so I cant be hundred percent sure everything returns correctly.

[molleweide]

What linux are you using?

[molleweide]

i have been searching a bit and I don't know if I have come up with anything useful yet, but it seems that you need a different command for locate on macos.

[molleweide]

You're preview looks good!

[cljoly]

What linux are you using?

Mostly Arch linux.

[cljoly]

You're preview looks good!

Thanks!

[molleweide]

Mostly Arch linux.

cool, my goal is to migrate to that in the future.

i find this thread on how to use locate on macos:
https://www.codeproject.com/Tips/5282703/Using-locate-databases-on-MacOS-Unix
BUT
there is also this saying that locate is not supported on mac and you should instead use a command called mdfind.
https://stackoverflow.com/questions/59881380/command-locate-in-mac-terminal.
https://metaredux.com/posts/2019/12/22/mdfind.html

I'm just posting here for reference. I have to look into this and see if you can create some kind of OS conditional.

[cljoly]

Yeah, I’ve found mdfind that seems to use spotlight’s cache (which is great), but it looks like it does not support hidden files (and I’m looking for .git to find the repos).

[cljoly]

Our posts crossed it seems :)

[molleweide]

Hmmm that's a bummer

[cljoly]

Looks like you can get locate installed on macos with brew: https://egeek.me/2020/04/18/enabling-locate-on-osx/

Wow I'll try that later today. It is wierd also because I get some indication it seems that some kind of locate exists on my machine but it doesn't have the -r flag. Hopefully it works without any mods with this brew package.

---- currently ----

If I run locate I get this but I cant do man locate (this not with the brew packacge. this is from before).

%> locate
usage: locate [-0Scims] [-l limit] [-d database] pattern ...

default database: `/var/db/locate.database' or $LOCATE_PATH

and I can use it to search but I don't know how to get help on it, i mean, eg. --help doesn't work, and it is not under man locate

[cljoly]

Yeah, I suspect the version of locate that you have installed currently does not support the -r but the findutils version should.

[molleweide]

allright, so now I have installed it and aliased it like so:

  alias locate="glocate -d $HOME/locatedb"

Should trepo pick up on this or do I have to change anything in the source you think?

[molleweide]

oh nvm now I think I understand how to add it.

[cljoly]

You would need the “more arguments” thing (not implemented yet) for the -d $HOME/locatedb bit, but glocate should work if passed to bin.

You should be able to test just by changing the command here

cool yeah I've tried that now and it does not work at first try.
ima take a pause now and come back later. but searching
the db in the terminal works.

[cljoly]

but searching
the db in the terminal works.

That’s great news!

[molleweide]

could flag order be of importance?

[cljoly]

I’m still thinking about a way to solve this…

[molleweide]

Me to haha

[molleweide]

I have thinking about this pretty much 24/7 for the last couple of days but this seems to be a bit above my level of nvim so I have had to spend some time on other stuff in the mean time but I am extremely looking forward to get some more time to look into this issue again because this is probably one of the most useful plugins ever.

[cljoly]

Thanks for your enthusiasm!

I’ve added some log messages (they may need adjustments so that it is less verbose, but for now it should be fine). You can see them by typing :messages.

When you have some time, maybe copy-pasting the output in a gist for me to look into would prove insightful.

[molleweide]

cool! I will try to do that tomorrow.
I also read a blog post that I found when searching around for how to reload plugins.

[cljoly]

If you still have the link, I would be interested, if only for comparison with what I do

[molleweide]

Yo!

I pulled locate branch and when I run the command it shows this:

:!open "https://www.reddit.com/search/?q=call_picker"

Press ENTER or type command to continue

and it open a reddit link in my web browser

[molleweide]

I simply created a command that calls Telescope reloader. This seems to work when I am in the directory working on the actual plugin BUT if I am in the dir of my vimrc, then running the command I cant find any packer modules. I don't understand why yet.

[molleweide]

This shows what the preview shows me when I search for telerepo with reloader in my vimrc dir.
As you can see, it only lists dirs from within the ~/.config dir.

[molleweide]

i created a new gist.
https://gist.github.com/molleweide/1ce6a71a0b31c8fab85fccf7d87345e0

[cljoly]

Thanks, I'll look into this in the next few days!

[cljoly]

It might be that telescope can’t execute the command for some reason, I’ll try to look deeper into this…

[molleweide]

Hmm interesting!! Tell me if you want me to do something for you

[molleweide]

Do you think that this would be grounds for a bug submission to telescope?

[cljoly]

Do you think that this would be grounds for a bug submission to telescope?

Maybe, I wanna read the docs some more first though.

[molleweide]

ooh i have to also read the built-in docs

[cljoly]

When I login to this GitHub Actions Workflow (that uses Mac OS), I can run:

nvim +'lua require"telescope".extensions.repo.cached_list{bin="glocate", locate_opts={"-d", "/Users/runner/locatedb"}}'

and after a few seconds, I get a list of repositories, like so:

@molleweide You won’t be able to log in to the action as it requires one of my private SSH keys, but maybe by comparing what’s done in the .yml, you will find what was wrong. For instance, it appears that $HOME does not work, as:

nvim +'lua require"telescope".extensions.repo.cached_list{bin="glocate", locate_opts={"-d", "/Users/runner/locatedb"}}'

works as intended, while:

nvim +'lua require"telescope".extensions.repo.cached_list{bin="glocate", locate_opts={"-d", "$HOME/loca
tedb"}}'

did not return any results.
I hope this helps you getting the plugin to work with locate on your Mac.

• I still need to find if there is a way to get a more verbose error when the command fails, it’s silent at the moment.

[molleweide]

yo I've seen that you wrote. I'll try to look at this and reply as soon as I can.
I'll also test this on my new M1 mac now as well.

[cljoly]

Thanks!

[molleweide]

No worries, i just wanted you to know I am following. I have a lot of stuff to do atm so I cant wait until I get to test this.

[cljoly]

@molleweide I’m going to merge this PR as it works for me on Linux and I want to further build on the code without creating more conflicts 😅 .

I’ve created a discussion (#13) to further investigate why the cached_list command did not work on Mac OS, when you have some time. We can then come back and make the necessary changes.
