Spaceship-prompt: Command slow in repository

[kamontat]

Current behavior

1. cd to <repository_path>
2. try to run git status 3x times
3. When I finish type, it just show the first command result
4. Cause in some repository only (Don't know, why)

I validate that the main problem should cause by this theme, since I try to change the new ones, git status will return as expected.

Expected behavior

1. git status shouldn't take that long time.

Relevant Zsh configuration (.zshrc)

Screenshot

Provide a screenshot that shows your issue. This is Video upload in Google drive

Possible solution

I think, It start slow when I instal NVM but not sure.

[salmanulfarzy]

Could you please upload screenshot directly here or to image hosting services like imgur rather than to Google Drive ?

[salmanulfarzy]

Do checkout prezto-contrib which makes it easy to install spaceship with prezto.

[kamontat]

I already try but not success.

[salmanulfarzy]

Excuse us for the trouble, Some of the sections you've enabled like battery and git_status affect performance, We're trying to improve performance of some sections with async rendering (#499).

If possible please try with different combinations of SPACESHIP_PROMPT_ORDER and let us know who is the culprit. Any help to improve prompt is appreciated.

[kamontat]

It found that the problem cause by node sections, since I currently install NVM.

[salmanulfarzy]

Lets leave this open until we improve the relevant section with async rendering.

[kamontat]

Ok.

[kamontat]

Any update?

[salmanulfarzy]

This will be mostly resolved with v4.0. Please follow the related issue #491

I really enjoy spaceship prompt, but recently do some linux kernel tinkering. It's not usable at all.
Try to clone
https://github.com/torvalds/linux/
then navigate the folders inside.
Getting the prompt back after a single ls takes more than 20 seconds, sadly.

Try to use any of the available async implementations of spaceship, async makes all the difference in the world 😉

[nebirhos]

@maximbaz that looks cool! I see there's an open PR, do you know when it will be merged?

In the meanwhile, which async implementation of spaceship do you suggest?

[maximbaz]

Personally I use my own fork with async implementation, but it seems #697 will be the approach that eventually gets merged, so maybe try that one and use the opportunity to provide feedback if something doesn't work as expected 😉

I know how much OSS maintainers hate "+1" replies, so hopefully I can be excused considering that I've also added a 👍 to this Issue.

I too am running into this problem, where much time is being spent between commands running spaceship code (at least a few seconds or more). I confirmed this by running set -x and observing the instructions being printed. On my shell, I have NVM lazy loading implemented (customized based on this gist). I added it because NVM was a major culprit to slow shell startup times. I've noticed that spaceship is slower if I have not yet lazy loaded nvm, but runs way faster if I have. Unfortunately, that kind of defeats the purpose of lazy loading NVM.

Unfortunately, I've been forced to turn off spaceship and use a different ZSH theme until this issue is resolved.

[kamontat]

@ecbrodie Maybe you might change version manager to asdf. I didn't use NVM for a long time because it so slow even we use lazyload.

[ecbrodie]

@kamontat convincing an entire software development organization to switch dozens of apps and several teams to use ASDF instead of NVM for downloading NodeJS is a non-starter for me. I'd like to see this project add improved support for the still-industry-standard tool for downloading NodeJS.

[nebirhos]

@maximbaz async PR #697 looks great, the prompt is much faster with git::async!

Unfortunately for some reason a lot of control sequences seem to not work anymore using that branch. For example, typing ctrl-a just prints the char instead of going to the beginning of the line:

~ 
[I] ➜ ^A

Not sure if that's related to that PR. I can send you more debugging information if needed.

[maximbaz]

Please post the details (and debugging info) in that PR, in this particular case I'd let the author of that PR investigate and fix these issues first 😉 But happy that async fixes the performance issue for you!
