st
st the suckless terminal or the simple terminal
most things here apply for dwm and other suckless software too
The examples below only assume you are running Linux (at the time of this writing, darwin/OS X does not support st).
Installing
NixOS
Add st to the list of available packages in your configuration.nix.
System-wide:
environment.systemPackages = with pkgs; [
st
];
Only available to certain users:
users.users.alice.packages = with pkgs; [
st
];
Other Linux distributions
You will need to write a roughly equivalent nix expression and install it the imperative way.
E.g.
my-custom-st
# pinned nixpkgs from nix.dev > "toward reproducibility"
{ pkgs ? import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/3590f02e7d5760e52072c1a729ee2250b5560746.tar.gz") {}
}:
# specifics elided for brevity
pkgs.st.overrideAttrs { ... }
Followed by:
$ nix-env -i -f my-custom-st
Patching
Most customization of st that alters its base feature set comes in the form of applying patches to the source code.
Obtaining hashes
To apply a patch you need to obtain the hash, the hash should be obtained with the following command
$ nix-prefetch-url <url>
example
$ nix-prefetch-url https://st.suckless.org/patches/rightclickpaste/st-rightclickpaste-0.8.2.diff
Patches
Can be applied by including them in an attribute override in your systemPackages declaration:
environment.systemPackages = with pkgs; [
(st.overrideAttrs (oldAttrs: rec {
patches = [
# You can specify local patches
./path/to/local.diff
# Fetch them directly from `st.suckless.org`
(fetchpatch {
url = "https://st.suckless.org/patches/rightclickpaste/st-rightclickpaste-0.8.2.diff";
sha256 = "1y4fkwn911avwk3nq2cqmgb2rynbqibgcpx7yriir0lf2x2ww1b6";
})
# Or from any other source
(fetchpatch {
url = "https://raw.githubusercontent.com/fooUser/barRepo/1111111/somepatch.diff";
sha256 = "222222222222222222222222222222222222222222";
})
];
}))
];
Patch Dependencies
Can be included with the buildInputs line like in the following ligature patch example:
environment.systemPackages = with pkgs; [
(st.overrideAttrs (oldAttrs: rec {
buildInputs = oldAttrs.buildInputs ++ [ harfbuzz ];
patches = [
(fetchpatch {
url = "https://st.suckless.org/patches/ligatures/0.8.3/st-ligatures-20200430-0.8.3.diff";
sha256 = "67b668c77677bfcaff42031e2656ce9cf173275e1dfd6f72587e8e8726298f09";
})
];
}))
];
Config
Configuration is accomplished through a config.h file.
Header file
environment.systemPackages = with pkgs; [
(st.overrideAttrs (oldAttrs: rec {
# Using a local file
configFile = writeText "config.def.h" (builtins.readFile ./path/to/local/config.h);
# Or one pulled from GitHub
# configFile = writeText "config.def.h" (builtins.readFile "${fetchFromGitHub { owner = "LukeSmithxyz"; repo = "st"; rev = "8ab3d03681479263a11b05f7f1b53157f61e8c3b"; sha256 = "1brwnyi1hr56840cdx0qw2y19hpr0haw4la9n0rqdn0r2chl8vag"; }}/config.h");
postPatch = "${oldAttrs.postPatch}\n cp ${configFile} config.def.h";
}))
];
All together now
environment.systemPackages = with pkgs; [
(st.overrideAttrs (oldAttrs: rec {
# ligatures dependency
buildInputs = oldAttrs.buildInputs ++ [ harfbuzz ];
patches = [
# ligatures patch
(fetchpatch {
url = "https://st.suckless.org/patches/ligatures/0.8.3/st-ligatures-20200430-0.8.3.diff";
sha256 = "67b668c77677bfcaff42031e2656ce9cf173275e1dfd6f72587e8e8726298f09";
})
];
# version controlled config file
configFile = writeText "config.def.h" (builtins.readFile "${fetchFromGitHub { owner = "me"; repo = "my-custom-st-stuff"; rev = "1111222233334444"; sha256 = "11111111111111111111111111111111111"; }}/config.h");
postPatch = oldAttrs.postPatch ++ ''cp ${configFile} config.def.h'';
}))
];
Using DWM
However, this will not work for dwm. (Probably services.xserver.windowManager.dwm can only see the dwm in pkgs, not the one in environment.systemPackages.) But you can use an overlay, like this:
nixpkgs.overlays = [
(self: super: {
dwm = super.dwm.overrideAttrs (oldAttrs: rec {
patches = [
./path/to/my-dwm-patch.patch
];
configFile = super.writeText "config.h" (builtins.readFile ./dwm-config.h);
postPatch = oldAttrs.postPatch or "" + "\necho 'Using own config file...'\n cp ${configFile} config.def.h";
});
})
];
It should also be mentioned that the st.overrideAttrs should be added to the overlays when using dwm with dwm changes and st changes the overlay could look like this
nixpkgs.overlays = [
(self: super: {
dwm = super.dwm.overrideAttrs (oldAttrs: rec {
patches = [
./path/to/my-dwm-patch.patch
];
configFile = super.writeText "config.h" (builtins.readFile ./dwm-config.h);
postPatch = oldAttrs.postPatch or "" + "\necho 'Using own config file...'\n cp ${configFile} config.def.h";
});
})
st = super.st.overrideAttrs (oldAttrs: rec {
patches = [
./path/to/my-dwm-patch.patch
];
configFile = super.writeText "config.h" (builtins.readFile ./st-config.h);
postPatch = "${oldAttrs.postPatch}\ncp ${configFile} config.def.h\n"
});
})
];
Remote config
If instead, you would prefer to build a pre-configured repository or realize more intense configuration, fork the mainline repository (or find one you like) and replace the value of the src attribute in the override.
Forks
Luke smiths st fork is used as the example
environment.systemPackages = with pkgs; [
(st.overrideAttrs (oldAttrs: rec {
src = fetchFromGitHub {
owner = "LukeSmithxyz";
repo = "st";
rev = "8ab3d03681479263a11b05f7f1b53157f61e8c3b";
sha256 = "1brwnyi1hr56840cdx0qw2y19hpr0haw4la9n0rqdn0r2chl8vag";
};
# Make sure you include whatever dependencies the fork needs to build properly!
buildInputs = oldAttrs.buildInputs ++ [ harfbuzz ];
# If you want it to be always up to date use fetchTarball instead of fetchFromGitHub
# src = builtins.fetchTarball {
# url = "https://github.com/lukesmithxyz/st/archive/master.tar.gz";
# };
}))
];
