[Monirzadeh]

@haashemi do you need any specific unit test?
work in progress this list will be update

• add basic unit test include
  • font.go
• add workflow to run test on any new PR

The workflow should have gcc, pkg-config, and harfbuzz-dev installed.

The main problem is that go-harfbuzz is developed on a higher harfbuzz version than what Ubuntu's apt has.

The best way I can think of is to lower go-harfbuzz's binding version. It means we just have to remove some features from it temporarily but still have them in another branch ready to release.

I'll fix that tomorrow as soon as I find some free time.

After doing a little bit more research, I found that harfbuzz versions on Ubuntu are so outdated (except Ubuntu 24.04) based on harfbuzz-versions

So, there are two things we should do:

1. Set the workflow runner to ubuntu-24.04 (which is beta)
2. Change the go-harfbuzz bindings to support harfbuzz 8.3.0

[Monirzadeh]

i change that to ubuntu 24.04 for now.
if you think it is not a good idea we can work on second approach before merge this.

Update: In order not to keep the pipeline broken until this PR is ready, I have done this in a separate PR #8.

[Monirzadeh]

i am not finish work on unittest :)
any way i will send another PR

[haashemi]

Oh... I'm so sorry...

It's my first time managing PRs and doing reviews; So make a lot of mistakes.

[Monirzadeh]
