Hang in VSCode's integrated terminal

[kidonng]

procs will hang if running in VSCode's integrated terminal, which is powered by xterm.js:

$ procs --debug 
Info: View::new [0.134s]
Info: view.filter [0.000s]
Info: view.adjust [0.000s]

(Hang)

I haven't test other programs that use xterm.js, but given that I don't have such issue with other programs, I guess procs is to blame.

I tried to reproduce it on the following environment, but all cases work fine.

• Linux / zsh
• Windows / PowerShell
• Windows / Command Prompt

Could you provide your environment?

[kidonng]

Sorry, my fault. I'm using the latest VSCode (1.56.0) on macOS 11.4 (20F5055c). This doesn't seem to be related to shell as I get the same result in bash/zsh/fish.
Is there any additional info needed?

Could you try procs --pager disable --theme dark?

[kidonng]

If I disable the pager, it works. 👍

[dalance]

Hmm, How about procs | less -SR?

[kidonng]

No issues.

Could you try the following repository?
https://github.com/dalance/pager-test

$ git clone https://github.com/dalance/pager-test
$ cd pager-test
$ cargo run

If you don't have Rust environment, I'll setup GitHub Actions for macOS binary later.

[kidonng]

You don't have to setup a CI, however I'm outside, will reply in an hour or two.

[kidonng]

The demo runs with no issue:

How about the latest commit?
dalance/pager-test@91d2af0

[kidonng]

Looks like the pager no longer works:

Screen.Recording.2021-05-10.at.15.17.14.mov

Also worth mentioning, setting LESSCHARSET=utf-8 doesn't help with procs.

[dalance]

Could you try to change less to the absolute path of less like below?

use pager::Pager;

fn main() {
    Pager::with_pager("/usr/bin/less -SR")
        .pager_envs(&["LESSCHARSET=utf-8"])
        .setup();
    println!("Hello, world!");
}

Additionally, removing pager_envs may be helpful to debug.

use pager::Pager;

fn main() {
    Pager::with_pager("less -SR")
        .setup();
    println!("Hello, world!");
}

[kidonng]

Both works (a. /usr/bin/less -SR with LESSCHARSET=utf-8 b. less -SR).

I fixed another bug, and released v0.11.6.
Is there any behaviour changing?

[kidonng]

Same issue.

[dalance]

Please let me reconfirm.
How about the followings?

procs --pager disable
procs --theme dark
procs --pager disable --theme dark

[kidonng]

I guess that's it. As long as I use --theme auto or don't specify --theme, it hangs.

[dalance]

Ok.
Could you try the following repository?
https://github.com/dalance/termbg

$ git clone https://github.com/dalance/termbg
$ cd termbg
$ cargo run

[kidonng]

Check terminal background color
  Term : XtermCompatible
  Color: detection failed Timeout { source: Timeout }
  Theme: detection failed Timeout { source: Timeout }

[dalance]

I tried to fix.
Could you try the latest commit of procs?

[kidonng]

The latest commit works 👍
Is this some kind of issue I can report to VSCode/xterm.js?

[dalance]

Thanks!
This is because VSCode/xterm.js doesn't support background color query by the xterm compatible way.
I think this is not bug, may be feature request.

[kidonng]

Maybe I will open an issue there later. Thanks for your patience and resolving the issue with me!

[dalance]

I released v0.11.7.
