CheckLspFile

Short description

🧩 CheckLspFile is an AutoCAD AutoLISP diagnostic utility for scanning a selected LSP source file for reader level syntax errors.
πŸ“‚ The command opens a file selection dialog rooted in a predefined @try folder and allows the user to select an LSP file for validation.
πŸ§ͺ The routine reads the file one line at a time and tests each line with the AutoLISP read function inside protected error handling.

Command:

Main command: CHKFILE

Functionalities:

βœ… LSP file selection – lets the user choose an AutoLISP source file through getfiled.
βœ… Line by line scanning – processes the selected source one line at a time.
βœ… Protected reader test – uses vl-catch-all-apply around the AutoLISP read function.
βœ… First error detection – stops when the first reader error is encountered.
βœ… Line number reporting – reports the source line where the reader problem was detected.
βœ… Problem text output – prints the offending source line for faster troubleshooting.
βœ… Reader error message – prints the trapped Visual LISP error message when available.

Result:
