Profiles

Activate profiles

A script to activate guix profiles.

Source: David Wilson's config

RED='\033[1;30m'
NC='\033[0m'
GUIX_EXTRA_PROFILES=$HOME/.guix-extra-profiles

profiles=$*
if [[ $# -eq 0 ]]; then
    profiles="$HOME/.config/guix/manifests/*.scm";
fi

for profile in $profiles; do
  # Remove the path and file extension, if any
  profileName=$(basename $profile)
  profileName="${profileName%.*}"
  profilePath="$GUIX_EXTRA_PROFILES/$profileName"
  manifestPath=$HOME/.config/guix/manifests/$profileName.scm

  if [ -f $manifestPath ]; then
    echo
    echo -e "${GREEN}Activating profile:" $manifestPath "${NC}"
    echo

    mkdir -p $profilePath
    guix package --manifest=$manifestPath --profile="$profilePath/$profileName"

    # Source the new profile

Update profiles

A script to update Guix profiles.

Source: once again, David Wilson's config.

GREEN='\033[1;32m'
NC='\033[0m'
GUIX_EXTRA_PROFILES=$HOME/.guix-extra-profiles

profiles=$*
if [[ $# -eq 0 ]]; then
    profiles="$GUIX_EXTRA_PROFILES/*";
fi

for profile in $profiles; do
  profileName=$(basename $profile)
  profilePath=$GUIX_EXTRA_PROFILES/$profileName

  echo
  echo -e "${GREEN}Updating profile:" $profilePath "${NC}"
  echo

  guix package --profile="$profilePath/$profileName" --manifest="$HOME/.config/guix/manifests/$profileName.scm"
done

Notes on installing software

Category	Guix dependency	Description
dev	patchelf	A program to modify existsing ELF executables
dev	glibc	A lot of stuff, including ELF interpeter and ldd

wakatime-cli

Note	Description
TODO	Package this for Guix

Before I figure out how to package this for Guix:

• Clone the repo
• Run go build
• Copy the binary to the ~/bin folder

ActivityWatch

Note	Description
TODO	Package this for Guix

The official binaries work just fine after some patching, except for the aw-qt binary.

Properly building from source is more awkward (PyInstaller? Are you serious? xD), as there are multiple packages with lots of dependencies.

The patching is as follows:

• Get ELF interpeter patch from guix build glibc, after which patch ELF interpeter path for the required binaries, e.g.:

patchelf --set-interpreter /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 aw-qt
patchelf --set-interpreter /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 aw-server/aw-server
patchelf --set-interpreter /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 aw-server-rust/aw-server-rust
patchelf --set-interpreter /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 aw-watcher-afk/aw-watcher-afk
patchelf --set-interpreter /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 aw-watcher-window/aw-watcher-window

Add libz to RPATH

Category	Guix dependency
misc	zlib

patchelf --set-rpath /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/ aw-qt
patchelf --set-rpath /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/ aw-server/aw-server
patchelf --set-rpath /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/ aw-server-rust/aw-server-rust
patchelf --set-rpath /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/ aw-watcher-afk/aw-watcher-afk
patchelf --set-rpath /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/ aw-watcher-window/aw-watcher-window

As aw-qt doesn't work properly, and the only thing it does is makes a tray icon anyhow, here is a script to launch the required components:

~/Programs/activitywatch/aw-server/aw-server &
~/Programs/activitywatch/aw-watcher-afk/aw-watcher-afk &
~/Programs/activitywatch/aw-watcher-window/aw-watcher-window &
