Hashline Edit

Use sl edit to make changes to code files. Always run sl read first to get current hashes.

Operations

Replace a single line

sl edit <file> 5#HH "new content for line 5"

Replace a range of lines

sl edit <file> 5#HH 10#QQ "replacement line 1\nreplacement line 2"

Append after a line

sl edit <file> --after 3#MQ "new line inserted after line 3"

Prepend before a line

sl edit <file> --before 1#ZP "header line added before line 1"

Delete lines

sl edit <file> --delete 5#HH 10#QQ

Multi-line content via stdin

echo -e "line1\nline2\nline3" | sl edit <file> 5#HH --stdin

Hash Mismatch

If you see Hash mismatch at line N, the file changed since your last sl read. Re-read the file to get updated hashes before editing.

Content Escapes

In content strings: \n = newline, \t = tab, \\ = backslash.

After Editing

Run sl read <file> again to verify changes and get updated hashes for further edits.
