trunc a template string

[nimaaskarian]

hey. i have been reading the manpages, the github readme and issues but i haven't found a way to truncate a format string; something like below (assuming $player is defined):

playerctl -F -p "$player" metadata --format '{{trunc("{{artist}} - {{title}} {{status}}", 50)}}'

my dwmblocks has a stack allocated array of size 50. and i really don't want the music status to be longer than that, without this option i have to call to head and truncate the output of the format string.

i think it would be amazing if there was a function that'd explicitly resolve the format strings.

I just studied the source code and I think this won't be implemented unless the whole template resolving code gets rewritten for the helper functions to get a context

[nimaaskarian]

ok i will do a PR.

also added binary addition between two strings (which appends the two)

[nimaaskarian]

there's this bug i haven't yet been able to fix. follow doesn't detect it should signal on pause/play when status is used in resolve helper function

I have also added an optional numerical third argument for trunc so you can disable appending ellipsis with passing it zero.

lol i just came to my senses that this app is unmaintained
