smlr

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.

Usage

[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), left or right. Default is middle alignment.

Examples

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

Installation

MacOS
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.
