The long lost Emacs string manipulation library.
M-x package-install s
Or you can just dump
s.el in your load path somewhere.
[[ function-list ]]
Documentation and examples
[[ function-docs ]]
What's with the built-in wrappers?
Imagine looking through the function list and seeing
s-starts-with? is nowhere to be found. Why? Well, because Emacs already has
string-prefix-p. Now you're starting out slightly confused, then have to go
somewhere else to dig for the command you were looking for.
The wrapping functions serve as both documentation for existing functions and makes for a consistent API.
Other string related libraries
inflections package provides functions for strings pluralization and singularization.
levenshtein package provides a function to calculate the Levenshtein distance between two strings.
string-utils is another general string manipulation library.

Yes, please do. Pure functions in the string manipulation realm only,
please. There's a suite of tests in
dev/examples.el, so remember to add
tests for your function, or I might break it later.
You'll find the repo at:
Run the tests with
Create the docs with
I highly recommend that you install these as a pre-commit hook, so that the tests are always running and the docs are always in sync:
cp pre-commit.sh .git/hooks/pre-commit
Oh, and don't edit
README.md directly, it is auto-generated.
