Previously we used nodePackages only to fetch Iosevka's build
dependencies and then fetched the source code ourselves. Updates
involved changing the version and hashes in the `iosevka` derivation and
then running node-packages/generate.sh to update the build dependencies,
which in turns updates *all* of node-packages.nix.
A new proposed policy for handling node-packages.nix updates involves
batching those updates. Previously, that would mean `iosevka` and its
build dependencies could end up out of sync until the batched update was
run.
To work with the new policy, we now fetch Iosevka's source code (and
not only its dependencies) through nodePackages. Updates are done by
changing the source URL in node-packages.json, which eventually becomes
part of an update of node-packages.nix, which is then propagated to
`iosevka` itself.
One con of this strategy is that errors can not be caught directly
after the update, but only after node-packages.nix is regenerated.
This adds the ability to select a specific prebuilt variant. It also adds
an updater script for generating their hashes. Additionally, switching
to TTC files reduces the package size by an order of magnitude.
Example usage:
fonts.fonts = with pkgs; [
(iosevka-bin.override { variant = "ss10"; })
(iosevka-bin.override { variant = "sparkle"; })
(iosevka-bin.override { variant = "aile"; })
];
I made a mistake merge. Reverting it in c778945806 undid the state
on master, but now I realize it crippled the git merge mechanism.
As the merge contained a mix of commits from `master..staging-next`
and other commits from `staging-next..staging`, it got the
`staging-next` branch into a state that was difficult to recover.
I reconstructed the "desired" state of staging-next tree by:
- checking out the last commit of the problematic range: 4effe769e2
- `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken
merge commit and its revert from that range (while keeping
reapplication from 4effe769e2)
- merging the last unaffected staging-next commit (803ca85c20)
- fortunately no other commits have been pushed to staging-next yet
- applying a diff on staging-next to get it into that state
This reverts commit c778945806.
I believe this is exactly what brings the staging branch into
the right shape after the last merge from master (through staging-next);
otherwise part of staging changes would be lost
(due to being already reachable from master but reverted).
