# Symconf
|
||||
`symconf` is a CLI tool for managing local application configuration. It implements a
|
||||
general model that supports dynamically switching/reloading themes for any application,
|
||||
and provides a basic means of templatizing your config files.
|
||||
# Overview
|
||||
`symconf` is a CLI tool for managing local application configuration. It uses a simple
|
||||
operational model that symlinks centralized config files to their expected locations across
|
||||
one's system. This central config directory can then be version controlled, and app
|
||||
config files can be updated in one place.
|
||||
|
||||
## Simple example
|
||||
Below is a simple example demonstrating two system-wide theme switches:
|
||||
`symconf` also facilitates dynamically setting system and application "themes," symlinking
|
||||
matching theme config files for registered apps and running config reloading scripts.
|
||||
|
||||
![Simple example](docs/_static/example.gif)
|
||||
For
|
||||
example, the following `symconf` call coordinates a light to dark mode switch
|
||||
|
||||
This GIF shows two `symconf` calls, the first of which applies a `gruvbox` dark theme and
|
||||
the second a dark [`monobiome`][1] variant. Each call (of the form `symconf config -m dark -s
|
||||
<style>`) indicates a dark mode preference and a particular color palette that should be
|
||||
used when populating config file templates. Specifically, in this example, invoking
|
||||
`symconf` results in the following app-specific config updates:
|
||||
|
||||
- **GTK**: reacts to the mode setting and sets `prefer-dark` system-wide, changing general
|
||||
GTK-responsive applications like Nautilus and Firefox (and subsequently websites that
|
||||
are responsive to `prefers-color-scheme`)
|
||||
- **kitty**: theme template is re-generated using the specified palette, and `kitty`
|
||||
processes are sent a message to live-reload the new config file
|
||||
- **neovim**: a `vim` theme file is generated from the chosen palette, and running
|
||||
instances of `neovim` are sent a message to re-source this theme
|
||||
- **waybar**: bar styles are updated to match the mode setting
|
||||
- **sway**: the background color and window borders are dynamically set to base palette
|
||||
colors, and `swaymsg reload` is called
|
||||
- **fzf**: a palette-dependent theme is re-generated and re-exported
|
||||
- **rofi**: launcher text and highlight colors are set according to the mode and palette,
|
||||
applying on next invocation
|
||||
|
||||
This example highlights the generality of `symconf`, and so long as an app's config can be
|
||||
reloaded dynamically, you can use a single `symconf` call to apply themes for an arbitrary
|
||||
number of apps at once.
|
||||
|
||||
# Behavior
|
||||
`symconf` uses a simple operational model that symlinks centralized config files to their
|
||||
expected locations across the system. This central config directory can then be version
|
||||
controlled, and app config files can be updated in one place.
|
||||
|
||||
App config files can either be concrete (fully-specified) or templates (to be populated by
|
||||
values conditional on style, e.g., a palette). When `symconf` is executed with a
|
||||
particular mode preference (dark or light) and a style (any other indicator of thematic
|
||||
elements, often simply in the form of a palette like `solarized` or `gruvbox`), it
|
||||
searches for both concrete and template config files that match and symlinks them to
|
||||
registered locations. When necessary, `symconf` will also match and execute scripts to
|
||||
reload apps after updating their configuration.
|
||||
|
||||
You can find more details on how `symconf`'s matching scheme works in
|
||||
[Matching](docs/reference/matching).
|
||||
|
||||
# Configuring
|
||||
Before using, you must first set up your config directory to house your config files and
|
||||
give `symconf` something to act on. See [Configuring](docs/reference/configuring) for
|
||||
details.
|
||||
|
||||
# Installation
|
||||
The recommended way to install `symconf` is via `pipx`, which is particularly well-suited
|
||||
for managing Python packages meant to be used as CLI programs. With `pipx` on your system,
|
||||
you can install with
|
||||
|
||||
```sh
|
||||
pipx install symconf
|
||||
```
|
||||
|
||||
You can also install via `pip`, or clone and install locally.
|
||||
|
||||
# Usage
|
||||
- `-h --help`: print help message
|
||||
- `-c --config-dir`: set the location of the `symconf` config directory
|
||||
- `symconf config` is the subcommand used to match and set available config files for
|
||||
registered applications
|
||||
* `-a --apps`: comma-separate list of registered apps, or `"*"` (default) to consider
|
||||
all registered apps.
|
||||
* `-m --mode`: preferred lightness mode/scheme, either `light`, `dark`, `any`, or
|
||||
`none`.
|
||||
* `-s --style`: style indicate, often the name of a color palette, capturing thematic
|
||||
details in a config file to be matched. `any` or `none` are reserved keywords (see
|
||||
below).
|
||||
* `-T --template-vars`: additional groups to use when populating templates, in the form
|
||||
`<group>=<value>`, where `<group>` is a template group with a folder
|
||||
`$CONFIG_HOME/groups/<group>/` and `<value>` should correspond to a TOML file in this
|
||||
folder (i.e., `<value>.toml`).
|
||||
|
||||
The keywords `any` and `none` can be used when specifying `--mode`, `--style`, or as a
|
||||
value in `--template-vars` (and we refer to each of these variables as _factors_ that help
|
||||
determine a config match):
|
||||
|
||||
- `any` will match config files with _any_ value for this factor, preferring config files
|
||||
with a value `none`, indicating no dependence on the factor. This is the default value
|
||||
when a factor is left unspecified.
|
||||
- `none` will match `"none"` directly for a given factor (so no special behavior), but
|
||||
used to indicate that a config file is independent of the factor. For instance,
|
||||
|
||||
```sh
|
||||
symconf config -m light -s none
|
||||
```
|
||||
|
||||
will match config files that capture the notion of a light mode, but do not depend on or
|
||||
provide further thematic components such as a color palette.
|
||||
|
||||
## Examples
|
||||
- Set a dark mode for all registered apps, matching any available style/palette component:
|
||||
|
||||
```sh
|
||||
symconf config -m dark
|
||||
```
|
||||
- Set `solarized` theme for `kitty` and match any available mode (light or dark):
|
||||
|
||||
```sh
|
||||
symconf config -s solarized -a kitty
|
||||
```
|
||||
- Set a dark `gruvbox` theme for multiple apps (but not all):
|
||||
|
||||
```sh
|
||||
symconf config -m dark -s gruvbox -apps="kitty,nvim"
|
||||
```
|
||||
- Set a dark `gruvbox` theme for all apps, and attempt to match other template elements:
|
||||
|
||||
```sh
|
||||
symconf config -m dark -s gruvbox -T font=mono window=sharp
|
||||
```
|
||||
|
||||
which would attempt to find and load key-value pairs in the files
|
||||
`$CONFIG_HOME/groups/font/mono.toml` and `$CONFIG_HOME/groups/window/sharp.toml` to be
|
||||
used as values when filling templatized config files.
