Context:
When using org files, one normally tends to add Github code links to an
algorithm/bug explanation so that readers are able to follow along with a PR
change.
The current `<SPC> g l L` command gets us the URL to the current branch; given
the code is in flux, the link becomes non-sensical rather quickly, loosing value
when trying to build a document with explanations about the code.
This PR allows us to get the Permalink (e.g. link associated to the commit, not
the branch); using this, the URL contents will never change with new commits
submitted to the repository.
Changes:
* Add two new functions with associated keybindings:
- `<SPC> g l p` maps to `spacemacs/git-permalink`
- `<SPC> g l P` maps to `spacemacs/git-permalink-copy-url-only`
* The above changes rely on mechanisms of `git-link`, so no new code needs to
be introduced
Magit now uses Transient instead of magit-popup, and we must adapt. Also had to
replace the recently removed magit-diff-buffer-file-popup with
magit-diff-buffer-file (similar but doesn't offer a popup before displaying the
diff).
Note some upstream packages haven't adapted to this change, but when they do we
might need similar fixes:
- magithub
- magit-gitflow
- magit-svn
problem: currently, viewing a file at a specific branch/commit, requires one to
type the magit-find-file command, at the M-x prompt
solution: SPC g f f is available and consistent with the SPC f f key binding
The `SPC g` command prefix was to much overloaded for actions which
are already available in discoverable manner in magit. So I decided to
remove all the actions reachable from magit-dispatch-popup from `SPC g`.
magit-dispatch-popup is available under `SPC g m`. This increases the
key binding sequences but OTHO it makes everythings consistent (same
key sequence behind `SPC g s` and `SPC g m`) and we prefer consistency.
This refactoring free up a lot of precious key bindings we can use for
commands that are not available in Magit.
