Truncates stdin to a maximum fixed size, abbreviating the output if over the specified length. For example, make a giant git branch name more manageable for use in PS1.
[source] | smlr [-s SIZE] [-a ALIGNMENT]
-s: Size of output. If equal or greater than input, input is relayed to s unchanged"). Default value is 5.-a: Alignment of output. Can be either middle (if option is omitted),leftorright. Default is middle alignment.
Bring your git branch down to a fixed-size:
> git rev-parse --abbrev-ref HEAD | smlr -s 10
> feat...-13
Deal with too many letters. Sometimes there are too many:
> echo "abcdefghijkl" | smlr -s 10 -a right
> ...fghijkl
> echo "abcdefghijkl" | smlr -s 10 -a left
> abcdefg...
A date string that's just too long:
> date | smlr -s 10
> Thu ...017
Repeat the string if it turns out to be equal, or smaller than, the size given:
> echo "abc" | smlr -s 5
> abc

Available via Macports: sudo port install smlr
General
Clone the repo and run a make to build it. If everything works out, you'll have a binary in build/rel/smlr. Symlink or copy that sucker to a path directory, such as /usr/bin.
