@lenml/apply_edits

Global CLI tool for batch file editing with SEARCH/REPLACE and MATCH/REPLACE patterns. Atomic transactions, sequential same-file simulation, encoding auto-detection.

Windows PowerShell Note: PowerShell 5 (powershell.exe) defaults to UTF-16 LE when piping, which breaks encoding. Upgrade to PowerShell 7+ (pwsh.exe). On PS5, pipe from a UTF-8 file instead of using here-strings.

Install

npm install -g @lenml/apply_edits

Usage

See SKILL.md for full documentation — command format, MATCH mode, multiple files, error handling, and API.

Tip: Code fences around blocks are optional. The autofixer adds them if missing.

Basic example (PowerShell 7+):

apply-edits --workspace . @'
src/main.py
<<<<<<< SEARCH
print("hello")
=======
print("hello world")
>>>>>>> REPLACE
'@

Or via heredoc (Bash):

apply-edits --workspace . << 'EOF'
src/main.py
<<<<<<< SEARCH
print("hello")
=======
print("hello world")
>>>>>>> REPLACE
EOF
