A simple configuration template rendering program.
The main goal of mold is to allow users to easily switch configuration files between different contexts. One example usage would be to have custom themes for multiple programs with one easy way to switch all of their configuration at once.
The context file contains multiple namespaces as well as a global namespace. Each namespace can
have multiple key-value entries. Those variables can then be used in the templates like this:
{% variable1 %}. The name of the variable is enclosed in {% and %} with any amount of
whitespace in between allowed.
There are also file source variables enclosed in {@ and @} that point to a path in the file system. When rendering a context contents of this file will be used in place of the variable. To trim the content of the file of whitespace use {@~ and ~@} tags.
Here is an example context file that could be used to render configuration:
renders:
alacritty.yml: ~/.config/alacritty/alacritty.yml
bspwm/bspwmrc: ~/.config/bspwm/bspwmrc
.gtkrc-2.0: ~/.config/.gtkrc-2.0 # ~ will correctly expand to the home directory
gtk-3.0/settings.ini: ~/.config/gtk-3.0/settings.ini
namespaces:
- name: GLOBAL
variables:
_font_: JetBrains Mono
_font_size_: '11'
alacritty.font: "{%_font_%}"
alacritty.font-size: "{%_font_size_%}"
_gtk_theme_: Aritim-Dark
gtk3.font.name: "{%_font_%}"
gtk3.font.size: "{%_font_size_%}"
gtk3.theme.name: "{%_gtk_theme_%}"
gtk3.icon-theme.name: "Papirus-Dark"
gtk2.theme.name: "{%_gtk_theme_%}"
gtk2.font.name: "{%_font_%}"
gtk2.font.size: "{%_font_size_%}"
#bspwm.screen.init: randr
bspwm.screen.init: randr rotate
_wallpapers_path_: /usr/share/wallpapers
vim.bg.light_or_dark: dark
- name: gruvbox
variables:
alacritty.theme: gruvbox
gtk3.theme.name: gruvbox-gtk
wallpaper.screen0: "{%_wallpapers_path_%}/gruvbox_vertical.png"
wallpaper.screen1: "{%_wallpapers_path_%}/gruvbox.png"
- name: solarized
variables:
alacritty.theme: solarized
gtk3.theme.name: Solarized-Dark-Orange
wallpaper.screen0: "{%_wallpapers_path_%}/solarized_vertical.png"
wallpaper.screen1: "{%_wallpapers_path_%}/solarized.png"If a variable value is not available in the specified namespace one from GLOBAL namespace will be used.
To install mold you'll need the latest rust with cargo.
$ cargo build --release && cp ./target/release/mold /usr/bin/If the context contains the renders field then it can be rendered directly with:
$ mold render-context context.yml
$ mold render-context context.yml -n some-namespaceIf you want to render files directly use the render subcommand:
$ mold render -c context.yml file1 file2 # will print both files to stdout
$ mold render -c context.yml file1 file2 -n some-namespace
$ mold render -c context.yml file1 file2 -o /tmp # will save the rendered files as /tmp/file1 and /tmp/file2$ mold diff -c context.yml gtkrc-template ~/.gtkrc-2.0 # will render gtkrc-template and show a diff with ~/.gtkrc-2.0You can checkout the context file that I use for my setup for further examples here
