Fixes #1992.

After installing HyDE on top of Hyprdots, Waybar never starts and fails with Json::Value::resolveReference(key, end): requires objectValue. Hyprdots kept its modules in ~/.config/waybar/modules/ as bare fragments ("cpu": { ... },) that its config generator pasted together into one object. HyDE includes every *json* file in that directory as a document of its own, and the installer never touches it, so the fragments survive the install. Waybar's parser stops after the first complete value, reads the fragment as the string "cpu", and aborts when it looks up that value's include key.

The new v26.10.1 migration moves every module in that directory that Waybar can't load to ~/.local/state/hyde/migration/v26.10.1/waybar/modules/, and HyDE's own modules in $XDG_DATA_HOME/waybar/modules/ take their place. A file is moved only when one of these is true, and each one aborts Waybar:

  • it is empty or holds only comments
  • its top-level value is not an object or an array
  • it has a ${...} placeholder outside a string (Hyprdots' header.jsonc)

Modules that load are left alone, including ${...} inside strings and comments, a byte order mark, and trailing commas. Nothing is deleted. A leftover that comes back identical to its backup is removed, and a different one never overwrites the backup.

I checked the rule against jsoncpp (the parser Waybar uses) on 393 files: Hyprdots' modules, every module and layout HyDE ships, and older HyDE module files from git history. Nothing that loads was moved, and all 31 Hyprdots modules were.

Tests: HyDE-Project/tests#45, test_waybar_hyprdots_modules.sh, which fails on current dev and passes with this branch.

Summary by CodeRabbit

  • New Features
    • Added migration handling for Waybar modules that cannot be loaded as standalone documents. These modules are moved to a versioned backup location and replaced by HyDE modules; modules that can be loaded are left in place.
    • Existing backups are preserved, and migration reports a failure if a backup conflicts with a different file or if a move cannot be completed.

Hyprdots kept its Waybar modules as bare fragments for its config
generator to paste together. HyDE includes every file in
~/.config/waybar/modules/ as a document of its own and never touches
that directory, so after installing on top of Hyprdots Waybar reads a
fragment as a string and aborts with "Json::Value::resolveReference(key,
end): requires objectValue".

The migration moves every module there that Waybar cannot load to a
backup, so HyDE's own modules take their place. Modules that load are
left alone.

Fixes HyDE-Project#1992

📝 Walkthrough

The v26.10.1 migration scans Waybar module files and moves files that meet its unloadable checks to a migration state directory. It leaves loadable files in place and handles existing backup files. The changelog records this migration.

Changes: Waybar module migration

Layer / File(s) Summary
Configure paths and detect unloadable modules
Scripts/migrations/v26.10.1.sh
The migration defines the config and backup paths, then checks matching module files. The scanner skips a leading BOM, comments, and string contents.
Move unloadable modules and handle existing backups
Scripts/migrations/v26.10.1.sh, CHANGELOG.md
The migration moves unloadable files to the backup directory. It removes the source when an identical regular file already exists there, and reports failure for conflicting destinations or filesystem operation errors. The changelog describes the migration.

Merge Risk: 🟡 Moderate · up to 2e76f

An existing backup symlink can cause the migration to remove the only copy of a Waybar module. Guard that collision before merging.

Explanation

Issue #1992 requires Waybar to appear after a HyDE install over Hyprdots. Scripts/migrations/v26.10.1.sh runs during restore, scans the legacy ~/.config/waybar/modules/*json* files, and moves the unloadable fragments to the migration backup path. It preserves loadable modules and does not delete files. The reported test_waybar_hyprdots_modules.sh test covers the Hyprdots case and passes with this change.

Full details: Out of Scope Changes check

Explanation

The changes are limited to the #1992 migration and its changelog entry. The migration backup, rerun handling, and preservation of loadable modules directly support the issue objective. No unrelated change is established by the supplied evidence.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 1 functions across 1 files. (1 skipped: 1 unsupported.)

Reject symlink destinations before removing the source.

If dst is a symlink to src, -f passes and cmp -s reports identical contents. rm -f "${src}" then removes the only copy of the module and leaves a dangling backup symlink. Check -L "${dst}" before the identical-backup branch so the existing collision branch preserves the source. (pubs.opengroup.org)
