Small text editor bootstrapped from cat

Project Files • GitHub Repo • st4.c

st4 is a nano-like screen editor bootstrapped from a ed-like line editor bootstrapped from cat and shell redirection. It directly emits VT100 escapes to standard output.

st4 is a work in progress. Current features include:

• virtual cursor support;
• automatic soft wrapping;
• C and Markdown ftdetect and syntax highlighting;
• configurable tabstops and toggleable line numbers;
• rendering and insertion of nonprintable characters.
