💡 Verification agent
🧩 Analysis chain
Verify the test logic matches the expected backslash handling behaviour.
The test expects backslashes to be repositioned during wrapping, but examine the actual wrap_text function implementation. The function doesn't appear to have specific logic for handling backslash line continuations - it treats them as regular characters. This suggests the test may be documenting desired behaviour rather than testing current implementation.
Run the following script to verify the current wrap_text function behaviour with backslash line continuations:
🏁 Script executed:
#!/bin/bash
# Description: Test the actual behaviour of wrap_text with backslash line continuations
# Expected: Determine if the function currently handles backslashes as documented in the test
# Search for backslash handling logic in the wrap_text function
ast-grep --pattern 'fn wrap_text($$$) {
$$$
}'
# Also search for any backslash-related logic in the entire file

Implement backslash line‐continuation support in wrap_text
wrap_text currently treats backslashes as ordinary characters, so the new wrap_text_respects_backslash_linebreaks test fails. Add explicit handling for trailing \ to preserve line breaks as documented:
• File: src/wrap.rs
Function: wrap_text
• In each input line, detect a trailing \ before wrapping.
– Strip the \ from the end of the current line.
– Perform normal word-wrapping on the remaining text.
– Prepend \ to the next wrapped line and continue wrapping its words.
• Verify behavior by re-running wrap_text_respects_backslash_linebreaks.
🤖 Prompt for AI Agents
In src/wrap.rs around lines 435 to 452, the wrap_text function does not
currently handle trailing backslashes as line continuations, causing the
wrap_text_respects_backslash_linebreaks test to fail. Modify wrap_text to detect
if a line ends with a backslash, remove that backslash before wrapping, then
prepend a backslash and space ("\ ") to the start of the next wrapped line to
preserve the line break semantics. After implementing this, re-run the
wrap_text_respects_backslash_linebreaks test to confirm correct behavior.
