## 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 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 directory. You will have to modify your `~/.bashrc` and/or `~/.profile` file to
at the end (preferably): add at the end (preferably):
``` ```bash
source <installpath>/profile/profile.sh source <installpath>/profile/profile.sh
``` ```
It's not recommended to load that profile in /etc/profile as the users' .bashrc 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`

## 3. Configuration ### 3.1. Prompt
Some functions might have configurable default behaviour. You can create a A bar-style prompt showing current time, execution time of the last command
profile.conf file to configure those default behaviour. You should have a look (with sub-millisecond precision), and the exit code of the last command.
at the doc/profile.conf.example to see the list of available options. The
configuration file is located in the same directory as profile.sh file.
## 4. Contact and more information ### 3.2. Functions reference
### 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!

Locale shortcut functions (`setfr`, `setus`, etc.) are dynamically generated at
startup from the `SET_LOCALE` configuration key (see section 4).
## 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.
### 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
Each module exposes its hardcoded defaults as configuration keys. Set a key to
change the default without having to pass flags every time.
**`[compress]`** — `taz` / `utaz`
| Key | Default | Description |
|---|---|---|
| `TAZ_DEFAULT_FORMAT` | `tar.gz` | Archive format for `taz` (`tar.gz`, `tar.bz2`, `tar.xz`, `zip`, …) |

|---|---|---|
| `UPDT_DEFAULT_BRANCH` | `master` | Git branch used for update checks and `profile_upgrade`. Changing this value causes `profile_upgrade` to automatically switch the local checkout to the new branch on the next run and display a warning. |
### 4.3. Locale shortcuts
The `[general]` 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.
### 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'
```

# 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. Development environment
| Requirement | Minimum version | Notes |
|---|---|---|
| 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
```
---
## 4. 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 `$(( … ))` in conditionals.
- **`local`** for all function-internal variables — avoid polluting the
environment.
- **`printf`** instead of `echo` wherever the format matters.
- **Never `eval`** — use namerefs (`local -n`), `${!varname}` indirection, or
`declare -g` instead.
- **No hardcoded defaults** — wire every configurable value through
`${VAR:-default}` and document the key in `profile.conf` and `README.md §4`.
### Function conventions
- Public functions **must** be exported: `export -f funcname`.
- Every public function **must** support `-h` / `--help` and print usage to
stdout, returning 0.
- Use `getopt` (not `getopts`) for option parsing — it handles long options and
`--` correctly.
- Follow existing error-return conventions: 0 = success, 1 = usage error,
2 = bad options, 3 = missing dependency, 4+ = runtime failure.
- Prefix all local helper variables with a short unique prefix (e.g. `_taz_`)
to prevent collisions with caller-scope variables.
### Module structure
Every new module should follow this pattern:
```bash
#!/usr/bin/env bash
# <copyright block identical to existing modules>
load_conf "<module_name>"
# --- functions ---
export -f my_function
# EOF
```
Add the `load_conf` call near the top after any variable declarations.
---
## 5. Configuration keys
When adding a configurable default:
1. Use `${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`.
---
## 6. 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.
---
## 7. 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.
---
## 8. 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.
```
---
## 9. 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.
---
## 10. Financial contributions
Contact the maintainer by mail if you wish to make a financial contribution.

# Frequently Asked Questions
---
## Installation & loading
**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: 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 `$(…)` — these are stripped by the
parser as a security measure.
---
## Prompt & theming
**Q: How do I change the prompt theme?**
Add to `profile.conf`:
```ini
[prompt]
PROMPT_THEME = dark
```
Built-in names: `default`, `dark`, `light`, `solarized`, `solarized-light`,
`monokai`, `monochrome`, `abyss`, `plasma`, `adwaita`.
---
**Q: The solarized or solarized-light theme shows wrong colours.**
Those themes use 24-bit / true-colour ANSI sequences (`\e[38;2;R;G;Bm`).
Test your terminal:
```bash
printf '\e[38;2;38;139;210mTrue colour test\e[0m\n'
```
If you see a solid blue word your terminal supports true colour.
If you see garbage or plain text, switch to a 16-colour theme
(`dark`, `default`, etc.) or upgrade your terminal emulator.
---
**Q: I created a custom theme but `load_theme` emits "key not allowed" warnings.**
Theme files are parsed, not executed. Only `PROMPT_COLOR_*` keys and the
standard colour variable names from `disp.sh` (`Black`, `Blue`, `On_IBlack`,
…) are accepted. Any other key — including custom variables — is rejected.
See `README.md §4.4` for the full list of accepted keys and value forms.
---
**Q: Can a theme file contain shell logic or `$(…)` 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
(`$Blue`) or a raw ANSI escape literal (`\e[0;34m`).
---
## Functions
**Q: `meteo` prints "No city specified" even though I set a default.**
The key is `METEO_DEFAULT_CITY` (not `DEFAULT_CITY`), and it must be in the
`[info]` section:
```ini
[info]
METEO_DEFAULT_CITY = Paris
```
---
**Q: `dwl` fails with "no download tool found".**
`dwl` requires one of `curl`, `wget`, or `fetch` to be installed.
Install curl:
```bash
# Debian / Ubuntu
apt-get install curl
# Fedora / RHEL
dnf install curl
```
Or set `DWL_PREFERRED_TOOL` in `[net]` to whichever tool you have.
---
**Q: `pkgs` does not find packages I know are installed.**
`pkgs` delegates to `dpkg -l` (Debian/Ubuntu) or `rpm -qa` (RHEL/Fedora).
If your distribution uses a different package manager (pacman, apk, brew …)
it is not yet supported. See `doc/todo.md` for the tracking issue.
---
**Q: `profile_upgrade` says "no update available" but I know there is one.**
`check_updates` compares the content of the remote `version` file against
`$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

# profile — to-do list
Items marked **[easy]**, **[medium]**, or **[hard]** give a rough effort hint.
Items marked **[breaking]** would change existing behaviour and require a
version-bump.
---
## Shell / compatibility
- [ ] **ZSH compatibility layer** — most functions work already; the remaining
blockers are `local -A` (no associative arrays in ZSH without `typeset -A`)
and `local -n` namerefs. A thin compatibility shim would open the project to
ZSH users. **[hard]**
- [ ] **Bash completion** — add a `profile.d/completion/` directory and write
`_profile_upgrade`, `_taz`, `_utaz`, `_meteo`, etc. completions so that
`<Tab>` works on all public functions. **[medium]**
- [ ] **`shellcheck` clean pass** — run `shellcheck -x profile.sh profile.d/*.sh`
and address every remaining warning (currently a handful of SC2034 and SC2086
items). Integrate as a pre-commit hook. **[easy]**
---
## 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]**
### packages
- [ ] **Additional backends** — add support for `pacman` (Arch), `apk` (Alpine),
`xbps-query` (Void), and `brew` (macOS). **[medium]**
### 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]**
