desed

Demystify and debug sed scripts from the comfort of your terminal

Desed is a command line tool with beautiful TUI that provides users with a comfortable interface and practical debugger, used to step through complex sed scripts. Some of the notable features include: * Preview variable values, both of them * See how will a substitute command affect pattern space before it runs * Step through sed script, both forward and backwards * Place breakpoints and examine program state * Hot reload and see what changes as you edit source code * Its name is a palindrome desed currently only supports GNU sed (gsed) because BSD sed doesn't support the execution annotation feature (the --debug argument of gsed) that desed depends on.
