Hey @puff-tw!
The reason we assumed GitLab is hosted on a subdomain is because GitLab recommends you to host your git instance on a subdomain rather than on a relative url.

As you can see in the code we've hardcoded the API url to be in the form of SUBDOMAIN.DOMAIN.XYZ /api/v4/projects/.

Furthermore I have tried working out a solution where the extension could pickup the relative URL from GitLab itself, but found no luck there. (Was reported by @huzisuke in #77 but closed it due to no feasible solution)

The solution you are recommending is that we have a custom field where we can punch in the relative URL? Where do you recommend we put the option?

One possible place I could figure out would be the extension popup -

That sounds like a feasible approach. Placing the option in the extension popup could work well.

I'll try working on that in this week, will keep you updated on this issue 😄

Thanks for requesting the feature and helping making SpanTree a better extension 🌳

A. site url detect

Was reported by @huzisuke in #77 but closed it due to no feasible solution

on gitlab page it has global variable gon
// tested on gitlab-ce 11.4.5, gitlab 14.4.1-ee

> gon.gitlab_url
'https://demo-site.com/gitlab'
> gon.relative_url_root
'/gitlab'

is this info enough for api url detect?

B. ui setting item

One possible place I could figure out would be the extension popup

if it have to leave a setting entry on GUI,
is it possible to place it at the span-tree main-panel,
which is easier to reach than extention icon (normal collapsed) menu

(like the octotree setting icon)

rough verify code

seems chrome extension js can't directly access page global variable.
I'm not familar with extension delelop, I just did a rough workaround to verify feasibility:

// it's based on content.js (from 0.0.5.0 extension dir) , formated by chrome F12

+var base_url = (document.head.innerHTML.match(/;gon.gitlab_url="(.*?)";/) || [,window.location.origin])[1];
+console.log('---spantree:', base_url);
var r = t(9669)
  , i = t.n(r)
  , o = t(3955);
const a = {
-   baseURL: `${window.location.origin}/api/v4/projects/`
+   baseURL: `${base_url}/api/v4/projects/`
}                                                                                                          

it works ( via chrome load unpacked modified extension dir )
