[StumpWM, bin] Add weather module to StumpWM, convert we to POSIX sh
Convert script `we` from fish to POSIX shell Add two new scripts: - stump-choose-city - stump-weather The former one sets the default city used for weather. The latter generates the output used by StumpWM’s mode-line.

A quick and useful script I often use is a ~curl~ request to [[http://v2.wttr.in/][v2.wttr.in]] to get a
|
||||
weather forecast in the terminal. By default, I want the request to be about the
|
||||
city I live in, but it is also possible for the script to accept as its
|
||||
arguments a search inquiry.

This script does two things. First, I get to choose a location which
|
||||
weather will be displayed in StumpWM’s mode-line. The script stores
|
||||
the selected location in the file ~$HOME/.cache/weather-city~, but only
|
||||
if the input is not an empty string, otherwise nothing will change.
|
||||
Secondly, if this change is applied, ~stump-weather~ (described below)
|
||||
is called in order to update what StumpWM displays.
|
||||
#+begin_src sh
|
||||
CITY=$(rofi -p "City:" -dmenu | sed -r 's/ +/\+/g')
|
||||
if [ -n "$CITY" ]; then
|
||||
printf "%s" "$CITY" > "$HOME"/.cache/weather-city
|
||||
stump-weather > /dev/null 2>&1

This stript is quite simple: it displays some weather information in
|
||||
the format /Location: weather temperature (felt temperature)/. We use
|
||||
the content of the file ~$HOME/.cache/weather-city~ to know which
|
||||
location to use in our request to ~wttr.in~. If ~wttr.in~ is unreachable
|
||||
after two second, the request aborts and the script displays an error
|
||||
message instead.

||||
