My .zshrc file

zshrc

All posts in here will have the category set to zsh.

setup org-babel

This helper function checks the tags of the current headline and returns a list of corresponding filenames. For instance if the tags are daily and pi, the function returns ‘(".zshrc" “.zshrc.pi”)

(setq tag-to-filenames-alist '(("daily" . ".zshrc")
                               ("blender" . ".zshrc.blender")
                               ("pi" . ".zshrc.pi")
                               ("android" . ".zshrc.android")
                               ("mips" . ".zshrc.mips")))
(defun org-tags-to-filenames ()
  (let ((tags (car (last (org-heading-components)))))
    (when (stringp tags)
      (remove nil (mapcar
                   (lambda (tag)
                     (cdr (assoc tag tag-to-filenames-alist)))
                   (org-split-string tags ":"))))))

zshrc

This is my .zshrc; it will be used in many environments:

daily driver (gentoo box with kde)
blender box (gentoo box with no gui)
android box in termux
raspberry pi
mips box

Each environment has slightly different setups, which will be tangled to different files according to the function `org-tags-to-filenames’, defined in the previous section.

Include

First, include a script that sets a number of confidential data (e.g. API keys and such)

source ~/.config/confidential.sh
# This defines a number of env variables:
# ANDROID_A3=xxxx
# ANDROID_BLU=xxx
# ANDROID_IP=xxx.xxx.xxx.xxx
# ifttt_apikey=xyz

Then, add helper directory to fpath

fpath=(~/clones/zshrc/ $fpath)

KDE helpers

Define a number of KDE helpers.

kde-current-activity returns the id of the current activity
kde-current-activity-name returns the name of the current activity

The other two swap between build and src dirs on my local git checkout

kde-current-activity () {
  qdbus org.kde.ActivityManager /ActivityManager/Activities org.kde.ActivityManager.Activities.CurrentActivity
}

kde-current-activity-name () {
  qdbus org.kde.ActivityManager /ActivityManager/Activities org.kde.ActivityManager.Activities.ActivityName `kde-current-activity`
}

kde-cd-build () {
    cd $(pwd | sed -e 's+scratch/src/kde+scratch/src/kde/build+')
}

kde-cd-src () {
    cd $(pwd | sed -e 's+scratch/src/kde/build+scratch/src/kde+')
}

TODO Factor the KDE tree dir

TODO See if we can use zsh expansion instead of sed

Android helpers

These are various helpers to drive my current Android phone when connected to the box.


     run-task () {
         adb -s $ANDROID_CUR shell am broadcast --user 0 -a net.dinglish.tasker.run_task -e task "$1"
     }

     android-remote-keyboard()
     {
         # should set this up in a tmux session
         adb -s $ANDROID_CUR shell ime set de.onyxbits.remotekeyboard/.RemoteKeyboardService;
         adb -s $ANDROID_CUR forward tcp:6023 tcp:2323;
         sleep 1;
         telnet 127.0.0.1 6023

         adb -s $ANDROID_BLU forward tcp:6028 tcp:2323;
         sleep 1;
         telnet 127.0.0.1 6028
     }

     setup-ipwebcam()
     {
         adb -s $ANDROID_BLU forward tcp:8097 tcp:8080
         ffmpeg  -i http://localhost:8097/video -map 0:v -pix_fmt yuv420p -f v4l2 /dev/video2
         adb -s $ANDROID_BLU forward --remove tcp:8097
     }

Misc helpers

tmux guard This function checks if we are in a tmux session before executing the command; otherwise print an error and bail out

 tmux-guard()
 {
if [[ -v TMUX ]]; then
   $@
 else
     echo tmux-guard: ensure you are in a tmux session to run $@
 fi
 }

wttr.in

wttr()
{
    local location=Toronto
    [[ $(tput cols) -le 124 ]] && local narrow=n;
    curl -H "Accept-Language: ${LANG%_*}" wttr.in/"${1:-$location}?T$narrow"
}

ifttt helper This sends the first argument as a maker event to IFTTT; the function defines some completions; is there a way to retrieve them from IFTTT?

curl -X POST https://maker.ifttt.com/trigger/$1/with/key/$ifttt_apikey

Define the completions (by hand for the time being)

#compdef ifttt

_ifttt() {
    integer ret=1
    local -a args
    args+=(
        '1:event to be sent:(table-light table-light-off wu1 wu2 goodnight wind-down)'
    )
    _arguments $args[@] && ret=0
    return ret
}

_ifttt

Load the function

autoload ifttt

This is an helper for moving a file to some other place and adding

a link back to the original position. bl stands for backlink

BIG FAT WARNING: this needs to specify an actual file as a destination (similar to ln) adding a directory would not work.

bl()
 {
 mv $1 $2
 ln $2 $1
}

konsole helpers

}

function set-konsole-title() {
    qdbus  "${KONSOLE_DBUS_SERVICE}" "${KONSOLE_DBUS_SESSION}" setTabTitleFormat 0 $1
}

function set-konsole-pomo-title() {
