 a customized prompt and several functions for different purposes. It's mostly

+targeted to system administrators but might satisfy some regular users.
 
-## 1. Getting started
+## 1. Requirements
+profile requires **Bash 4.3 or higher** (for associative arrays and namerefs).
+It will refuse to load on older versions and will also refuse to load if the
+current shell is not bash.
+
+## 2. Getting started
 Download and extract (or use git clone) the profile archive into your home
-directory. You will have to modify your ~/.bashrc and/or ~/.profile file to add
-at the end (preferably):
-```
+directory.
+
+The profile is designed to be **sourced**, not executed directly.
+
+Manual setup:
+```bash
 source <installpath>/profile/profile.sh
 ```
 
-It's not recommended to load that profile in /etc/profile as the users' .bashrc
+Automatic setup (recommended):
+```bash
+bash <installpath>/profile/profile.sh --install
+```
+
+`--install` appends the required `source` line to both `~/.bashrc` and
+`~/.profile` by default. You can target one file only:
+
+```bash
+bash <installpath>/profile/profile.sh --install --bashrc
+bash <installpath>/profile/profile.sh --install --profile
+```
+
+You may also set the `PROFILE_PATH` environment variable before sourcing if you
+want to override the automatic path detection:
+```bash
+export PROFILE_PATH=/opt/profile
+source /opt/profile/profile.sh
+```
+
+It's not recommended to load that profile in `/etc/profile` as users' `.bashrc`
 files might interfere with some aliases and functions defined in profile.
 
-## 2. What's the purpose?
-profile is giving access to numerous functions, aliases and to an advanced
-prompt. Here is a non-exhaustive list of what we have:
-- A bar style prompt with hour, execution time and exit code of the last
-command;
-- clean: erase after confirmation any backup file, possibly recursively;
-- dpkgs: search for the given pattern in the installed packages name;
-- expandlist: usefull in scripts, it expand any expression using wildcards into
-the corresponding list of file and directories;
-- genpwd: generate one or more random secure password;
-- gpid: give the list of PID matching the given process name;
-- help: display the list of available function and basic use;
-- isipv4: tell if the given parameter is a valid IPv4 address;
-- isipv6: tell if the given parameter is a valid IPv6 address;
-- ku: kill all the processes owned by the given user name or ID;
-- mcd: create a directory and immediately move into it;
-- meteo: display weather forecast information;
-- ppg: look for the given patern in the running processes;
-- rain: console screensaver with rain effect;
-- rmhost: remove the given host (name or IP) to the list of SSH known host;
-- rmspc: in the current directory it replace all the spaces in filenames with a
-underscore caracter (or any other given in option);
-- setc: set locale on standard C;
-- setfr: set locale on French;
-- settrace: allow the debugging of any script by showing a backtrace in case of
-error;
-- setus: set locale on US English;
-- showinfo: display basic informations about the host;
-- ssr: root ssh login to the given host;
-- taz: a universal command to compress files and directories, possibly several
-at once;
-- utaz: a utility that smartly uncompress many archives at once, creating a
-directory only if needed;
-- ver: show profile version.
+### 2.1. Interactive vs non-interactive shells
 
-## 3. Configuration
-Some functions might have configurable default behaviour. You can create a
-.profile.conf file to configure those default behaviour. You should have a look
-at the doc/.profile.conf.example to see the list of available options.
+`profile.sh` detects whether the current shell is interactive.
 
-## 4. Contact and more information
-### 4.1. New users
-This project is very new in terms of publication, and I have no idea of who will
-use it, if any does. If you use (or plan to use) ```profile```, I'll be very
-happy if you simply mail me to let me know, especially if you don't plan to
-contribute. If you plan to contribute, I'll be twice happier for sure!
+In interactive shells (typical terminal sessions), profile enables
+interactive-only features such as:
+- aliases from `[aliases]`
+- bash completion scripts from `profile.d/bash-completion/`
+- prompt initialization (`PROMPT_COMMAND` and timer hook)
+- welcome display (`showinfo`) and startup update check (`check_updates -q`)
 
-### 4.2. Bugs
+In non-interactive shells (typical script execution), those features are
+intentionally skipped to avoid side effects and startup noise. Public functions
+remain available after sourcing, so scripts can still call profile helpers.
+
+### 2.2. Initial configuration
+Copy the example configuration file and customise it to your needs:
+```bash
+cp <installpath>/profile/doc/profile.conf.example <installpath>/profile/profile.conf
+```
+`profile.conf` is git-ignored so your personal settings will never be
+accidentally committed. All keys are optional — sensible defaults apply when
+unset. See [section 4](#4-configuration) for the full reference.
+
+## 3. What's the purpose?
+profile gives access to numerous functions, aliases and to an advanced prompt.
+All functions are organized into modules under the `profile.d/` directory and
+are loaded automatically at startup.
+
+### 3.1. Prompt
+A bar-style prompt showing current time, execution time of the last command
+(with sub-millisecond precision), and the exit code of the last command.
+
+### 3.2. Functions reference
+

+| `ppg` | processes | Look for the given pattern in running processes |
+| `ppn` | processes | List processes matching an exact command name |
+| `ppu` | processes | List processes owned by a specific user |
+| `profile_upgrade` | updates | Upgrade profile to the latest version (git pull or archive) |

+| `ver` | info | Display the installed profile version |
+
+Locale shortcut functions (`setfr`, `setus`, etc.) are dynamically generated at
+startup from the `SET_LOCALE` configuration key (see section 4).
+
+### 3.3. Bash completion
+
+profile loads all `*.sh` files found under `profile.d/bash-completion/`
+automatically in interactive sessions. This directory is the right place to add
+any custom completion definitions. profile already ships completions for its git
+helper functions there (`git-completion.sh`).
+
+## 4. Configuration
+profile uses an INI-style configuration file (`profile.conf`) located in the
+same directory as `profile.sh`. Sections are declared with `[section_name]` and
+keys follow `key = value` syntax. Each module calls `load_conf "<section>"` at
+load time, which exports every key in that section as an environment variable.
+Unknown keys are silently ignored; all keys are optional — sensible defaults
+apply when unset.
+
+`profile.conf` is listed in `.gitignore` so personal values (API keys, cities,
+compiler flags, …) are never accidentally staged. Start from the annotated
+template at `doc/profile.conf.example` (see [section 2.2](#22-initial-configuration)).
+
+### 4.1. Core sections
+
+| Section | Purpose |
+|---|---|
+| `[system]` | Bash history size, pager, and other shell behaviours |
+| `[general]` | General-purpose variables (e.g. compilation flags, `MAKEFLAGS`) |
+| `[aliases]` | User command aliases, loaded for interactive shells only |
+
+### 4.2. Module defaults

+change the default without having to pass flags every time.

+
+### 4.3. Locale shortcuts
+
+The `[lang]` key `SET_LOCALE` accepts a comma-separated list of
+`alias:locale` pairs. Each pair generates a function of that name at startup:
+
+```ini
+SET_LOCALE = fr:fr_FR.UTF-8, us:en_US.UTF-8
+```
+
+This creates `setfr` and `setus`. Use `setlocale <locale>` to switch to any
+installed locale directly.
+
+Set `DEFAULT_LANG` to one of the defined aliases to activate that locale
+automatically at login:
+
+```ini
+DEFAULT_LANG = fr
+```
+
+If `DEFAULT_LANG` is set but does not match any alias in `SET_LOCALE`, a
+warning is displayed and no locale change is applied.
+
+### 4.4. Prompt theming
+
+The prompt appearance is controlled by two mechanisms that are applied in order
+(later values win):
+
+1. **Theme file** — sets a base colour palette.
+2. **`[prompt]` section** in `profile.conf` — per-key overrides on top of the theme.
+
+**Selecting a theme:**
+
+```ini
+[prompt]
+PROMPT_THEME     = dark          # bare name → profile.d/themes/dark.theme
+PROMPT_THEME_DIR = ~/.mythemes   # optional: custom search directory
+```
+
+Built-in themes: `default`, `dark`, `light`, `solarized`, `solarized-light`,
+`monokai`, `monochrome`, `abyss`, `plasma`, `adwaita`.
+
+**Overriding individual prompt colour slots:**
+
+```ini
+[prompt]
+PROMPT_COLOR_USER_FG = $ICyan
+PROMPT_COLOR_DIR_FG  = $IYellow
+```
+
+The eleven available `PROMPT_COLOR_*` keys are:
+
+| Key | Role |
+|---|---|
+| `PROMPT_COLOR_TIME_FG` / `TIME_BG` | Clock foreground / background |
+| `PROMPT_COLOR_BAR_BG` | Main bar background |
+| `PROMPT_COLOR_OK_FG` / `OK_MARK` | Exit-code text / checkmark on success |
+| `PROMPT_COLOR_ERR_BG` / `ERR_FG` / `ERR_MARK` | Error bar background / text / X mark |
+| `PROMPT_COLOR_ROOT_FG` | Username colour when running as root |
+| `PROMPT_COLOR_USER_FG` | Username@host colour for normal users |
+| `PROMPT_COLOR_DIR_FG` | Working directory colour |
+
+**Writing a custom theme file:**
+
+Theme files live in `profile.d/themes/` and use the `.theme` extension. They
+are **parsed, not executed** — no shell code runs. Only two value forms are
+accepted:
+
+```ini
+# Colour variable reference (resolved from profile.d/disp.sh)
+PROMPT_COLOR_DIR_FG = "$ICyan"
+
+# Raw ANSI escape sequence (single block, 16-colour or 24-bit true-colour)
+PROMPT_COLOR_BAR_BG = "\e[48;2;7;54;66m"
+```
+
+Any unknown key, unsafe value, or shell construct is discarded with a warning.
+Theme files may also override the standard colour variables (`Black`, `Blue`,
+`On_IBlack`, etc.) to remap the entire terminal palette used by `ls`, `grep`,
+and other colour-aware tools.
+
+True-colour themes (`solarized`, `solarized-light`) require a terminal with
+24-bit colour support (Konsole, iTerm2, kitty, Alacritty, Windows Terminal).
+Verify support with:
+```bash
+printf '\e[38;2;38;139;210mTrue colour test\e[0m\n'
+```

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format follows [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+Versions follow `MAJOR.MINOR.PATCH-REVISION_STAGE_N` (e.g. `3.99.1-4_rc_1`).
+
+---
+
+## [4.1.0] — 2026-05-07
+
+### Added
+- `profile.sh --install` command to automatically configure profile loading in
+  shell startup files.
+- `--install --bashrc` and `--install --profile` target selectors for
+  single-file installation.
+- **`git.sh`** — entirely new module providing git workflow helpers: `gst`,
+  `ggraph`, `gsync`, `gacp`, `greset`, `gwip`, `gprune`, `groot`.
+- Dedicated git helper completions under `profile.d/bash-completion/`, loaded
+  automatically in interactive sessions from `profile.d/bash-completion/*.sh`.
+
+### Changed
+- `disp` now wraps long messages on terminal width, avoids mid-word splits, and
+  aligns continuation lines with the message body after the prefix.
+- `help` now supports `help <command>` and delegates to `<command> --help`.
+- `taz` now supports `-p auto` / `--parallel=auto` to automatically use the
+  runtime CPU count. This mode is now the default via
+  `TAZ_DEFAULT_THREADS=auto`.
+- `taz` keeps backward compatibility with legacy `TAZ_DEFAULT_THREADS=0`
+  values by interpreting `0` as `auto`.
+
+### Fixed
+- Startup responsiveness improved: `check_updates -q` now uses a short network
+  timeout so unavailable/slow networks no longer delay prompt readiness.
+- `dwl` gained timeout support (`-t` / `--timeout`) and is now used by quiet
+  startup update checks to enforce fast failure.
+- `profile.sh` now detects direct execution and warns that it is designed to be
+  sourced.
+
+## [4.0.0] — 2026-04-23
+
+### Added
+- New `profile.conf` reference template at `doc/profile.conf.example`.
+- Dynamic locale shortcuts generated from `SET_LOCALE` and startup default
+  language selection through `DEFAULT_LANG`.
+- Prompt theming system with bundled themes (`default`, `dark`, `light`,
+  `solarized`, `solarized-light`, `monokai`, `monochrome`, `abyss`, `plasma`,
+  `adwaita`) and per-key prompt color overrides.
+- Module defaults exposed as configuration keys in `profile.conf`.
+
+### Changed
+- `utaz` now supports a wider range of archive formats.
+- Prompt and theme rendering improved, including better 24-bit color support.
+- Overall code quality and maintainability improved across modules.
+
+### Documentation
+- README updated with full function reference and configuration tables.
+- New and expanded docs in `doc/` (`CONTRIBUTING.md`, `FAQ.md`, `todo.md`).
+- Historical releases imported from `history.txt` into this changelog.

+## [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.
+
+---
+
+## [3.95.3-4_beta_3] — 2024
+
+### Added
+- Initial public release candidate series.
+- Core modules: `compress`, `disp`, `filefct`, `fun`, `help`, `info`, `lang`,
+  `net`, `packages`, `processes`, `prompt`, `pwd`, `rain`, `ssh`, `updates`.
+- Bar-style prompt with time, command duration, and exit code.
+- `taz` / `utaz` archive helpers.
+- `genpwd` / `pwdscore` password tools.
+- `matrix` / `rain` screensavers.
+- `profile_upgrade` with git and archive download support.

+# Contributing to profile
+
+Thank you for your interest in contributing. This document explains how to get
+set up, what the conventions are, and how to submit work.
+
+---
+
+## 1. Before you start
+
+- Check the [to-do list](./todo.md) to see if your idea is already planned.
+- Check the [issue tracker](https://git.geoffray-levasseur.org/fatalerrors/profile/issues)
+  to avoid duplicate work.
+- For significant changes, open an issue or contact the maintainer before
+  writing code — alignment on design saves everyone time.
+
+---
+
+## 2. Getting the source
+
+A Git clone is mandatory for contributions:
+
+```bash
+git clone https://git.geoffray-levasseur.org/fatalerrors/profile.git
+cd profile
+```
+
+Always work from the **latest commit on `master`** (or the branch you intend
+to target). Stale forks cause avoidable merge conflicts.
+
+---
+
+## 3. Branch policy
+
+| Branch | Purpose |
+|---|---|
+| `master` | Main development branch — new features and enhancements go here |
+| `<version>` (e.g. `3.x`) | Maintenance branch for a released version — bugfixes backported from `master` |
+
+**New functionality** must always target `master`.
+
+**Bugfixes** must target the branch where the bug was introduced:
+- If the bug exists in a released version, open the fix against that version's
+  maintenance branch first, then cherry-pick onto `master`.
+- If the bug is only in `master` (unreleased), fix it directly on `master`.
+- During a release-candidate cycle, bugfixes go on the `x.*` branch and are
+  merged back into `master` before the final release.
+
+Do **not** add new features to a maintenance branch.
+
+---
+
+## 4. Versioning scheme
+
+Versions follow the format **`MAJOR.MINOR.PATCH`** where the `MINOR` number
+conveys the development stage of the next major release:
+
+| Minor range | Stage | Rules |
+|---|---|---|
+| `x.90.y` | **Alpha** toward `x+1` | Stays on `master`. Development is open: new features are welcome, regressions are acceptable. |
+| `x.95.y` | **Beta** toward `x+1` | The `x+1.*` maintenance branch is created at this point. No regression unless absolutely necessary; new features still allowed. |
+| `x.99.y` | **RC** toward `x+1` | Bugfixes only. No new features. No regression allowed. Becomes `x+1.0.0` when stable. |
+
+Examples: `3.90.1` is the first alpha toward `4.0`, `3.99.2` is the second
+release candidate for `4.0`.
+
+The `PATCH` number increments freely within a stage. A bump in `MINOR`
+(e.g. `90` → `95`) always indicates a stage promotion in development phase.
+
+Any experimental version must have it's dedicated branch.
+
+---
+
+## 5. Development environment
+|---|---|---|
+| Bash | 4.3 | Namerefs (`local -n`) required |
+| shellcheck | any recent | Run before every commit |
+| git | any | For contributing patches |
+| bats-core | 1.x | Optional — for running the test suite |
+
+Install shellcheck:
+```bash
+# Debian / Ubuntu
+apt-get install shellcheck
+
+# Fedora / RHEL
+dnf install ShellCheck
+
+# macOS
+brew install shellcheck
+```
+
+---
+
+## 6. Code style
+
+### General rules
+- **Bash only** — no external interpreters in core modules. Python or Perl is
+  acceptable for completely self-contained, optional utilities that have no
+  dependencies beyond a minimal Debian or CentOS installation.
+- **4-space indentation** — no tabs.
+- **`[[ … ]]`** for all conditionals — not `[ … ]`.
+- **`(( … ))`** for arithmetic — not `$(( … ))` in conditionals.
+- **`local`** for all function-internal variables — avoid polluting the
+  environment. Prefer upper case for global and lowercase for local.
+- **`printf`** instead of `echo` all the time.
+- **Never `eval`** — use namerefs (`local -n`), `${!varname}` indirection, or
+  `declare -g` instead.
+- **No hardcoded defaults** — wire every configurable value through
+  `${VAR:-default}` and document the key in `profile.conf` and `README.md §4`.
+
+### Function conventions
+- Public functions **must** be exported: `export -f funcname`.
+- Every public function **must** support `-h` / `--help` and print usage to
+  stdout, returning 0.
+- Use `getopt` (not `getopts`) for option parsing — it handles long options and
+  `--` correctly.
+- Follow existing error-return conventions: 0 = success, 1 = usage error,
+  2 = bad options, 3 = missing dependency, 4+ = runtime failure.
+- Prefix all local helper variables with a short unique prefix (e.g. `_taz_`)
+  to prevent collisions with caller-scope variables.
+
+### Module structure
+Every new module should follow this pattern:
+
+```bash
+#!/usr/bin/env bash
+# <copyright block identical to existing modules>
+
+load_conf "<module_name>"
+
+# --- functions ---
+
+export -f my_function
+
+# EOF
+```
+
+Add the `load_conf` call near the top after any variable declarations.
+
+---
+
+## 7. Configuration keys
+
+When adding a configurable default:
+
+1. Use `${MY_VAR:-hardcoded_default}` in the function body.
+2. Add a commented-out entry with a description to `profile.conf`.
+3. Document the key in the matching table in `README.md §4.2`.
+
+---
+
+## 8. Theming
+
+New theme files go in `profile.d/themes/` with a `.theme` extension.
+They are **parsed, not executed** — do not add shell logic.  
+See the existing themes and `README.md §4.4` for the allowed syntax.
+
+---
+
+## 9. Running shellcheck
+
+```bash
+shellcheck -x profile.sh profile.d/*.sh
+```
+
+All warnings must be resolved before a patch will be accepted. Accepted
+suppression directives (`# shellcheck disable=SCxxxx`) require an inline
+comment explaining why the suppression is necessary.
+
+---
+
+## 10. Submitting a contribution
+
+### Via Git (preferred)
+1. Contact the maintainer to obtain push access, or fork on the Gitea instance.
+2. Create a branch: `git checkout -b feature/my-feature`.
+3. Commit with a clear subject line: `module: short description (≤ 72 chars)`.
+4. Push and open a pull request against `master`.
+
+### Via patch
+If you do not have push access:
+```bash
+git format-patch origin/master
+```
+Send the resulting `.patch` file(s) to
+`fatalerrors <at> geoffray-levasseur <dot> org`.
+
+### Commit message format
+```
+module: imperative short description
+
+Optional longer explanation of what changed and why. Wrap at 72 characters.
+Reference issue numbers if applicable: closes #42.
+```
+
+---
+
+## 11. What will be rejected
+
+- Code requiring packages not in a minimal Debian or CentOS install.
+- Use of `eval`, `source`-based config loading, or other code-injection vectors.
+- Changes that break Bash 4.3 compatibility.
+- Patches without a passing `shellcheck` run.
+- New functions without `--help` support.
+

+# Frequently Asked Questions
+
+---
+
+## Installation & loading
+
+**Q: How do I install profile automatically into my shell startup files?**
+
+Run the installer directly (no need to source first):
+```bash
+bash <installpath>/profile/profile.sh --install
+```
+This appends the required `source` line to both `~/.bashrc` and `~/.profile`.
+To target only one file:
+```bash
+bash <installpath>/profile/profile.sh --install --bashrc
+bash <installpath>/profile/profile.sh --install --profile
+```
+The operation is idempotent — running it again will not add a duplicate line.
+
+---
+
+**Q: I ran `profile.sh` directly and got a warning about sourcing.**
+
+profile.sh is designed to be *sourced*, not executed:
+```bash
+source <installpath>/profile/profile.sh
+```
+The only exception is `--install`, which must be passed to a direct execution
+(`bash profile.sh --install`) to set up the sourcing line automatically.
+
+---
+
+**Q: profile refuses to load and prints "This profile requires Bash 4.3 or higher."**
+
+Your system's default shell is an older Bash (common on macOS, which ships
+Bash 3.x for licensing reasons). Install a newer Bash:
+```bash
+# macOS
+brew install bash
+# then add /opt/homebrew/bin/bash to /etc/shells and chsh
+```
+Or point your terminal emulator at the newer binary explicitly.
+
+---
+
+**Q: I sourced `profile.sh` but functions are not available in sub-shells or scripts.**
+
+All public functions are exported with `export -f`. They are available in
+child Bash processes, but **not** in POSIX `sh` sub-shells. Make sure your
+scripts start with `#!/usr/bin/env bash`.
+
+---
+
+**Q: Can I use profile functions in scripts?**
+
+Yes. The supported way is to source `profile.sh` from a Bash script:
+```bash
+#!/usr/bin/env bash
+source /path/to/profile/profile.sh
+
+taz -p auto -f lz mydir
+```
+You can also source one module directly (for example
+`profile.d/compress.sh`) if you only need a subset of functions.
+
+When you source a module directly, profile configuration parsing/loading from
+`profile.sh` is skipped, so defaults from `profile.conf` are not applied unless
+your script loads them explicitly.
+
+`profile.sh` also detects whether the current shell is interactive. In
+non-interactive shells (typical script execution), interactive-only features
+are intentionally disabled: prompt setup, aliases, welcome/info messages, and
+startup update checks are not enabled.
+
+In all cases, avoid aliases in scripts. Use real commands/functions instead,
+because alias expansion is interactive-shell oriented and can be disabled or
+behave differently in non-interactive execution.
+
+---
+
+**Q: I set `PROFILE_PATH` but profile still can't find its modules.**
+
+`PROFILE_PATH` must be exported *before* you source `profile.sh`:
+```bash
+export PROFILE_PATH=/opt/profile
+source /opt/profile/profile.sh
+```
+If set after sourcing, `MYPATH` is already locked in and the variable has
+no effect.
+
+---
+
+**Q: Can I load profile system-wide via `/etc/profile`?**
+
+It is not recommended. User `.bashrc` files frequently set variables that
+conflict with the aliases and locale functions defined here, leading to
+surprising behaviour. Per-user sourcing from `~/.bashrc` is the supported
+method.
+
+---
+
+## Configuration
+
+**Q: I edited `profile.conf` but my changes have no effect.**
+
+`profile.conf` is parsed once per shell session at load time. Open a new
+terminal (or `exec bash`) to pick up the changes. There is no live-reload.
+
+---
+
+**Q: How do I find out which configuration keys a module supports?**
+
+Every supported key is documented with a comment in `profile.conf`.
+See also `README.md §4.2` for a consolidated table.
+
+---
+
+**Q: A key I set in `profile.conf` is being ignored.**
+
+Check that:
+1. The key is inside the correct `[section]` header.
+2. There is no leading space before the section name (`[section]` not
+   `[ section ]`).
+3. The key is not commented out (no leading `#`).
+4. The value contains no backticks or `$(…)` — these are stripped by the
+   parser as a security measure.
+
+---
+
+## Prompt & theming
+
+**Q: How do I change the prompt theme?**
+
+Add to `profile.conf`:
+```ini
+[prompt]
+PROMPT_THEME = dark
+```
+Built-in names: `default`, `dark`, `light`, `solarized`, `solarized-light`,
+`monokai`, `monochrome`, `abyss`, `plasma`, `adwaita`, but you can create your
+own theme.
+
+---
+
+**Q: The solarized or solarized-light theme shows wrong colours.**
+
+Those themes use 24-bit / true-colour ANSI sequences (`\e[38;2;R;G;Bm`).
+Test your terminal:
+```bash
+printf '\e[38;2;38;139;210mTrue colour test\e[0m\n'
+```
+If you see a solid blue word your terminal supports true colour.  
+If you see garbage or plain text, switch to a 16-colour theme
+(`dark`, `default`, etc.) or upgrade your terminal emulator.
+
+---
+
+**Q: I created a custom theme but `load_theme` emits "key not allowed" warnings.**
+
+Theme files are parsed, not executed. Only `PROMPT_COLOR_*` keys and the
+standard colour variable names from `disp.sh` (`Black`, `Blue`, `On_IBlack`,
+…) are accepted. Any other key — including custom variables — is rejected.
+See `README.md §4.4` for the full list of accepted keys and value forms.
+
+---
+
+**Q: Can a theme file contain shell logic or `$(…)` command substitutions?**
+
+No, and intentionally so. Theme files are parsed line-by-line; shell
+constructs are never evaluated. This is a security boundary — a malicious
+theme file cannot execute code. Values must be a colour variable reference
+(`$Blue`) or a raw ANSI escape literal (`\e[0;34m`).
+
+---
+
+## Git helpers
+
+**Q: What git helper functions does profile provide?**
+
+All git helpers are defined in `profile.d/git.sh` (new in 4.1.0):
+
+| Command | Purpose |
+|---|---|
+| `gst` | Compact status with branch tracking info |
+| `ggraph` | Decorated history graph |
+| `gsync` | Fetch and rebase onto upstream |
+| `gacp` | Add, commit and push in one command |
+| `greset` | Reset to upstream, stashing local changes first |
+| `gwip` | Quick WIP checkpoint commit |
+| `gprune` | Delete merged local branches |
+| `groot` | Print or cd to repository root |
+
+All commands accept `-h` / `--help`.
+
+---
+
+**Q: Tab completion for `gacp` does not show modified files.**
+
+Profile ships dedicated completions in `profile.d/bash-completion/git-completion.sh`,
+loaded automatically in interactive sessions. If completions are missing,
+check that the system git completion is installed:
+```bash
+# Debian / Ubuntu
+apt-get install bash-completion
+# Fedora / RHEL
+dnf install bash-completion
+```
+When the native git completion helpers are available, `gacp` path completion
+behaves exactly like `git add` (modified files, untracked files, directories).
+
+---
+
+**Q: `gacp` says "No files specified" even though I passed `-a`.**
+
+The `-a` / `--auto` flag adds all modified files (equivalent to `git add -A`).
+The default depends on `GIT_GACP_AUTO_ADD` in `profile.conf`:
+```ini
+[git]
+GIT_GACP_AUTO_ADD = 1
+```
+Set to `1` to make `-a` the default.
+
+---
+
+## Functions
+
+**Q: `meteo` prints "No city specified" even though I set a default.**
+
+The key is `METEO_DEFAULT_CITY` (not `DEFAULT_CITY`), and it must be in the
+`[info]` section:
+```ini
+[info]
+METEO_DEFAULT_CITY = Paris
+```
+
+---
+
+**Q: `dwl` fails with "no download tool found".**
+
+`dwl` requires one of `curl`, `wget`, or `fetch` to be installed.
+Install curl:
+```bash
+# Debian / Ubuntu
+apt-get install curl
+
+# Fedora / RHEL
+dnf install curl
+```
+Or set `DWL_PREFERRED_TOOL` in `[net]` to whichever tool you have.
+
+---
+
+**Q: How do I limit how long `dwl` waits for a download?**
+
+Use the `-t` / `--timeout` option:
+```bash
+dwl -t 5 https://example.com/file.txt /tmp/file.txt
+```
+This sets a 5-second cap on both the connection and the overall transfer.
+The timeout is propagated to `curl` (`--max-time` + `--connect-timeout`),
+`wget` (`--timeout`), or `fetch` (`-T`) transparently.
+
+---
+
+**Q: The prompt takes a long time to appear when my network is unavailable.**
+
+Fixed in 4.1.0. `check_updates -q` (called at startup) now enforces a
+3-second network timeout. If the update server is unreachable the check
+fails silently and the prompt appears immediately.
+
+---
+
+**Q: `help` only shows a list of functions. Can I get usage for a specific one?**
+
+Yes — pass the command name as an argument:
+```bash
+help gacp
+help dwl
+help taz
+```
+This calls `<command> --help` and prints the full usage for that function.
+
+---
+
+**Q: `pkgs` does not find packages I know are installed.**
+
+`pkgs` uses `get_pkgmgr` to detect the active package manager and delegates
+to the appropriate tool. Supported families: `apt` (Debian/Ubuntu),
+`dnf` / `yum` (RHEL/Fedora), `zypper` (openSUSE), `pacman` (Arch),
+`apk` (Alpine), `portage` (Gentoo), `xbps` (Void), `nix`, `brew` (macOS).
+If your distribution is not detected, run `get_pkgmgr` to see what is
+identified, and check that the package manager binary is in your `PATH`.
+
+---
+
+**Q: `profile_upgrade` says "no update available" but I know there is one.**
+
+`check_updates` compares the content of the remote `version` file against
+`$PROFVERSION`. If `UPDT_DEFAULT_BRANCH` in `[updates]` points to a different
+branch than your installation, the version files may not match. Check:
+```bash
+cat "$MYPATH/version"
+```
+and make sure `UPDT_DEFAULT_BRANCH` matches the branch you track.
+
+---
+
+## Compatibility
+
+**Q: Some functions misbehave on macOS / Cygwin.**
+
+Both environments ship non-GNU userland utilities with different flags and
+behaviour. profile is primarily developed and tested on Linux (Debian and
+RHEL families). macOS and Cygwin bugs are low priority; patches that add
+compatibility without breaking Linux support are welcome.
+
+---
+
+**Q: Can I use profile with ZSH?**
+
+Not officially. Blockers include `local -A` (ZSH requires `typeset -A`) and
+`local -n` namerefs. A compatibility layer is listed in `doc/todo.md` but
+has not been implemented yet.
+
+---
+
+## Miscellaneous
+
+**Q: How do I completely disable profile for one session?**
+
+```bash
+PROFILE_DISABLED=1 bash --norc
+```
+Or simply open a shell without sourcing `~/.bashrc` (`bash --norc`).
+
+---
+
+**Q: How do I report a bug?**
+
+Open an issue on the
+[Gitea tracker](https://git.geoffray-levasseur.org/fatalerrors/profile/issues)
+or send a mail to `fatalerrors <at> geoffray-levasseur <dot> org` with:
+- The exact command that triggered the bug
+- Your OS and Bash version (`bash --version`)
+- The module involved
+- Any relevant error output

+## Prompt & theming
+
+- [ ] **Git branch in prompt** — show the current branch name (and dirty
+  indicator) in the PS1 bar when inside a Git repository. Should be
+  gated behind a `[prompt]` config key so it can be disabled. **[medium]**
+- [ ] **Virtual-env / conda indicator** — detect `$VIRTUAL_ENV` / `$CONDA_DEFAULT_ENV`
+  and display the name in the prompt bar. **[easy]**
+- [ ] **True-colour terminal auto-detection** — query `$COLORTERM` and
+  `$TERM` at load time; automatically fall back from a 24-bit theme to its
+  16-colour equivalent when the terminal does not support true colour. **[medium]**
+- [ ] **True-colour variants of other themes** — create `monokai-tc.theme`,
+  `abyss-tc.theme`, etc. using the same `\e[38;2;R;G;Bm` approach as the
+  Solarized themes. **[easy]** _(per theme)_
+- [ ] **Theme preview command** — add a `theme_preview` (or `profile_theme`)
+  function that renders a colour swatch and a sample prompt line for the
+  currently loaded theme, so users can evaluate themes without reloading
+  the session. **[medium]**
+- [ ] **`load_theme` — DEFAULTCOL rebuild** — after overriding `DEFAULTFG` and
+  `DEFAULTBG`, automatically recompute `DEFAULTCOL` from the new values instead
+  of requiring the theme file to set it explicitly. **[easy]**
+
+---
+
+## Module improvements
+
+### compress
+- [ ] **`taz` progress bar** — show a `pv` / `dd`-based progress indicator when
+  compressing large trees, gated behind a `-p` flag. **[medium]**
+- [ ] **`utaz` integrity check** — run `tar -tOf` / `unzip -t` / `7z t` before
+  extracting and abort if the archive is corrupt. **[easy]**
+
+### filefct
+- [ ] **`findbig` / `findzero` / `finddead` — `fd` integration** — optionally
+  use `fd` instead of `find` when available for faster traversal. **[easy]**
+- [ ] **`file_stats` — human-readable totals** — add `--human` flag to emit
+  sizes in K/M/G instead of bytes. **[easy]**
+
+### info
+- [ ] **`showinfo` fallback** — when neither `neofetch` nor `fastfetch` is
+  installed, print a minimal sysinfo block (hostname, OS, kernel, uptime,
+  CPU, RAM) using pure Bash + `/proc`. **[medium]**
+
+### net
+- [ ] **`dwl` resume support** — pass `-C -` to curl / `--continue-at -` to
+  wget for interrupted downloads; gate behind a `-r` flag. **[easy]**
+- [ ] **`myextip` multiple providers** — fall back to a secondary URL
+  (configurable via `MYEXTIP_FALLBACK_URL`) when the primary times out.
+  **[easy]**
+
+### processes
+- [ ] **`ku` dry-run flag** — add `-n` / `--dry-run` to print what would be
+  killed without acting. **[easy]**
+
+### pwd
+- [ ] **`genpwd` passphrase mode** — add `-w` / `--words N` to generate
+  word-based passphrases (diceware-style) from `/usr/share/dict/words`.
+  **[medium]**
+
+### ssh
+- [ ] **SSH agent management** — add `ssh_agent_start` / `ssh_agent_stop` helpers
+  that start a persistent `ssh-agent`, add configured keys, and survive
+  re-login via a socket stored in `~/.ssh/agent.env`. **[medium]**
+- [ ] **`rmhost` glob support** — allow `rmhost '*.example.com'` to remove all
+  matching entries in one call. **[easy]**
+
+### updates
+- [ ] **Automatic update check age** — store a timestamp in `~/.cache/profile_last_check`;
+  skip the network request in `check_updates -q` if the last check was less
+  than `UPDT_CHECK_INTERVAL` hours ago (configurable, default 24). **[medium]**
+- [ ] **Changelog display** — after a successful `profile_upgrade`, fetch and
+  display `CHANGELOG.md` entries newer than the previously installed version.
+  **[medium]**
+
+---
+
+## Infrastructure
+
+- [ ] **Test suite** — add a `test/` directory with `bats` (Bash Automated
+  Testing System) unit tests for pure functions (`expandlist`, `genpwd`,
+  `pwdscore`, `isipv4`, `isipv6`, `parse_conf`, `load_theme`, …). Target for
+  CI. **[hard]**
+- [ ] **CI pipeline** — Gitea Actions (or similar) job that runs `shellcheck`
+  and the `bats` suite on every push. **[medium]**
+- [ ] **`profile_status` function** — print a diagnostic summary: installed
+  version, active theme, loaded modules, detected Bash version, interactive /
+  login shell flags, and `profile.conf` path. **[easy]**
+- [ ] **`profile_uninstall` function** — remove the `source` line from
+  `~/.bashrc` / `~/.profile` and optionally delete the install directory,
+  with a dry-run mode. **[medium]**
+- [ ] **`disp` syslog integration** — add a `DISP_SYSLOG=1` config key that
+  additionally pipes E/W messages to `logger`. **[easy]**
+- [ ] **XDG base-dir support** — honour `$XDG_CONFIG_HOME` as an alternative
+  location for `profile.conf` so users can keep `~` tidy. **[medium]**
+  **[breaking]**

+# Solarized Dark prompt theme — exact 24-bit / true-colour palette
+# ------------------------------------------------------------------------------
+# Theme files are NOT executed as shell scripts. load_theme() parses them
+# line by line. Only the following value forms are accepted:

+#   KEY="$ColorVarName"    — reference to a colour variable from disp.sh
+#   KEY="${ColorVarName}"  — same with braces
+#   KEY="\e[...m"          — raw ANSI escape sequence (single block)
+#
+# Accepted keys:
+#   PROMPT_COLOR_*         — prompt slot colours (see profile.conf [prompt])
+#   Standard colour vars   — Black, Blue, On_IBlack, … (overrides the palette
+#                            from disp.sh for the whole shell session)
+#
+# Any unknown key, unsafe value, or shell construct will be ignored with a
+# warning — theme files cannot execute code.
