ModuleManifest gains a structured [[permissions]] field (bread-shared's
new ModulePermission/PermissionKind, shared between bread-cli and breadd
so the two never drift on what a permission "type" string means).
breadd now gives every third-party module's Lua chunk a scoped _ENV
instead of the shared global table: load_scoped_lua_file builds a fresh
`bread` table containing only baseline bindings (event subscription,
timers, json, module/store, logging, and the pure-Lua sugar built on top
of those) plus whatever the manifest's permissions grant, with a
metatable __index falling back to the real globals for everything else
(stdlib, require/package - so require("bread.devices") keeps working,
since builtins load unscoped and their closures capture that environment
lexically regardless of the caller's). _G is explicitly rebound to the
scoped table itself to close the obvious escape hatch. A module with no
manifest, or a manifest with no permissions key, keeps full ambient
access unchanged (today's behavior) but is now tracked as `ungated` in
module status and surfaced by `bread doctor`. An explicit `permissions =
[]` is scoped for real but not flagged, since that's a deliberate
declaration.
Adds `bread modules audit <name>`: a best-effort text scan of a module's
.lua files suggesting a [[permissions]] block to paste into its manifest.
Converts examples/modules/cpu-temp-widget.lua into a directory module
with a worked bread.module.toml (fs.read + widget) as the reference
example. Documentation.md gets a new "Capability-scoped modules" section
covering the taxonomy, the require()/closure mechanism, and an explicit
note that path/bin scoping is recorded but not yet enforced per-call -
that's the out-of-process module sandboxing workstream this manifest
schema is laid down for. API_VERSION bumped 1.4.0 -> 1.5.0.

Example bread modules
Ready-to-use modules for common desktop automations. Unlike the snippets in
../../Examples.md (which teach the porting patterns),
these are complete files you can drop in as-is.
Installing
Modules in ~/.config/bread/modules/ are auto-discovered — copy a file in
and reload; no init.lua edit needed:
cp low-battery-warning.lua ~/.config/bread/modules/
bread reload
cpu-temp-widget/ is a directory (not a flat file) with a bread.module.toml
manifest declaring its [[permissions]] — see
Capability-scoped modules.
Either copy the whole directory into ~/.config/bread/modules/, or install it
properly so the manifest travels with it:
bread modules install ./cpu-temp-widget
bread reload
The other modules here are flat files with no manifest — they load exactly
like today, with full, ungated bread.* access (bread doctor will note
that). Run bread modules audit <name> on an installed one any time to get a
suggested [[permissions]] block for its own bread.module.toml.
Modules
| File | What it does | Config needed |
|---|---|---|
low-battery-warning.lua |
Critical notification once when the battery runs low; resets on AC. | none |
pause-media-on-headphone-unplug.lua |
Runs playerctl pause when a headphone/earbud device disconnects. |
none (needs playerctl) |
dock-monitors.lua |
Applies a multi-monitor layout when an external display connects, reverts when removed. | edit output names/resolutions |
active-window-widget.lua |
Shows the focused window next to the workspace pills in breadbar, via bread.widget + bread.state.watch. |
none |
cpu-temp-widget/ |
Live CPU temperature readout in breadbar's stats area, via bread.widget + bread.fs.read on a timer. Directory module with a bread.module.toml declaring fs.read + widget — the permission-manifest worked example. |
edit TEMP_PATH for your hwmon layout |
bluetooth-toggle-widget.lua |
One-click Bluetooth power toggle in breadbar's tray, via bread.widget + a click handler. |
none |
focus-mode-widget.lua |
Click-to-toggle "Focus" profile that mutes audio; a widget as an action launcher, not just a readout, and stays in sync with profile changes triggered elsewhere. | none (needs wpctl) |
workflow-status-widget.lua |
Surfaces bread.workflow.list() in breadbar's tray — shows whichever workflow (e.g. dock-workflow.lua, below) is currently running or failed, hidden otherwise. |
none |
git-branch-widget.lua |
Shows the repo + branch of whichever git repo the focused kitty tab is sitting in; yellow when dirty. Entirely self-contained in Lua — no adapter behind it. | kitty remote control (see the module's header comment) |
Each module is the standard skeleton — bread.module{...}, an on_load that
registers subscriptions, return M — so they double as references for writing
your own. See ../../Documentation.md for the full
event list and Lua API.
