## [3.99.2-4_rc_2] — 2026-04-21

### Fixed
- **`prompt.sh`** — `\$Last_Command` in PS1 was escaped, preventing the exit
  code from ever appearing in the prompt (the local variable no longer exists
  when PS1 is rendered by bash). Removed the backslash so the value is embedded
  at `set_prompt` build time.
- **`filefct.sh` — `file_stats()`** — a stray unconditional `shift` after
  `esac` doubled-shifted arguments already shifted by each `case` branch;
  successive options such as `-H -d` were silently skipped.
- **`packages.sh` — `pkgs()`** — replaced the unreliable binary-presence test
  (`command -v dpkg / rpm`) with the new `get_pkgmgr` function. Also corrected
  a typo in the "no package manager" error message (`avialable` → `available`).
- **`processes.sh` — `kt()`** — copy-paste error: usage error message read
  `"Usage: ppg <string>"` instead of `"Usage: kt <pid>"`.

### Added
- **`packages.sh` — `get_pkgmgr()`** — new exported helper that detects the
  active package manager of the running distribution. Detection first reads
  `/etc/os-release` (`ID` then `ID_LIKE`), then falls back to a
  fixed-priority binary scan. Supported families: `apt`, `dnf`, `yum`,
  `zypper`, `pacman`, `apk`, `portage`, `xbps`, `nix`. Returns 1 when
  nothing is identified. Available to all future commands in `packages.sh`.

## [3.99.1-4_rc_1] — 2026

### Added
- **Theming system** — `load_theme` in `profile.d/prompt.sh` loads `.theme`
  files from `profile.d/themes/` (or a custom directory set via
  `PROMPT_THEME_DIR`). Theme files are **parsed, not executed** — no shell code
  ever runs from a theme.
- **Built-in themes** — `default`, `dark`, `light`, `solarized` (24-bit
  true-colour), `solarized-light` (24-bit), `monokai`, `monochrome`, `abyss`,
  `plasma`, `adwaita`.
- **`[prompt]` section** — `PROMPT_THEME` and `PROMPT_THEME_DIR` keys to select
  a theme; eleven `PROMPT_COLOR_*` keys for per-key overrides in `profile.conf`.
- **Standard colour variables as theme keys** — theme files may also override
  the `disp.sh` colour variables (`Black`, `Blue`, `On_IBlack`, …) to remap the
  terminal palette used by `ls`, `grep`, and colour-aware tools.
- **Module configuration defaults** — all modules now expose their hardcoded
  defaults as `profile.conf` keys: `TAZ_*`, `UTAZ_*`, `EXPANDLIST_*`,
  `CLEAN_*`, `RMSPC_*`, `FINDBIG_*`, `RAIN_*`, `MATRIX_*`, `SSH_DEFAULT_OPT`,
  `GENPWD_*`, `PWDSCORE_*`, `BUSY_*`, `METEO_DEFAULT_CITY`, `DWL_*`,
  `MYEXTIP_*`, `PKGS_*`, `PPU_*`, `KU_*`, `UPDT_DEFAULT_BRANCH`.
- **`UPDT_DEFAULT_BRANCH`** — configures the git branch used by `check_updates`
  and `profile_upgrade`. Changing the key causes `profile_upgrade` to
  automatically switch the local checkout to the new branch and display a
  warning.
- **`doc/` directory** — `CONTRIBUTING.md`, `FAQ.md`, `profile.conf.example`
  (annotated template), `todo.md`.
- **`.gitignore`** — `profile.conf` is now git-ignored so personal settings are
  never accidentally staged.

### Changed
- README §2 now explains how to create `profile.conf` from
  `doc/profile.conf.example` (new section 2.1 "Initial configuration").
- README §4 updated with full module-defaults tables, theming reference, and a
  note about `profile.conf` being git-ignored.
- Theme values no longer carry the `export` keyword (they are not shell
  variables, only data).

### Security
- `load_theme` uses a strict allowlist (no `eval`, no sourcing). Only
  `PROMPT_COLOR_*` keys and known `disp.sh` colour variable names are accepted.
  Values must match `\$[A-Za-z_][A-Za-z0-9_]*` or `\\e\[[0-9;]*m`; any other
  value is discarded with a warning.
