## What it is
s.el is a string manipulation library for Emacs written in Emacs Lisp, providing a comprehensive set of functions for trimming, splitting, joining, padding, truncating, and testing strings. It is available on MELPA and designed as a convenient API layer over Emacs's built-in string operations.

## Use cases
- manipulate strings in emacs lisp code
- trim and pad strings in emacs
- split and join strings in elisp
- check if a string starts with or ends with a prefix or suffix
- truncate long strings for display in emacs
- extract regexp matches from strings in elisp

## When to choose
- you write Emacs Lisp packages and want readable string helpers instead of raw built-ins
- you need consistent, well-tested string utilities across your Emacs configuration
- you want a small dependency available directly from MELPA

## When to avoid
- you are not working in Emacs or Emacs Lisp
- you only need one or two string operations that built-in Emacs functions already cover
- you need unicode-heavy or locale-aware text processing beyond simple manipulation

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools
- domain: developer-tools, text-editors
- platform: editor-plugin
- tags: emacs, emacs-lisp, string-manipulation, melpa, text-processing
