Short description
🧩 CheckLspFile is an AutoCAD AutoLISP diagnostic utility for scanning a selected LSP source file for reader level syntax errors.
📂 The command opens a file selection dialog rooted in a predefined @try folder and allows the user to select an LSP file for validation.
🧪 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
Description:
🧩 CheckLspFile is an AutoCAD AutoLISP diagnostic utility for scanning a selected LSP source file for reader level syntax errors.
📂 The command opens a file selection dialog rooted in a predefined @try folder and allows the user to select an LSP file for validation.
🧪 The routine reads the file one line at a time and tests each line with the AutoLISP read function inside protected error handling.
Helper function: (if any)
Functionalities:
✅ LSP file selection – lets the user choose an AutoLISP source file through getfiled.
✅ Line by line scanning – processes the selected source one line at a time.
✅ Protected reader test – uses vl-catch-all-apply around the AutoLISP read function.
✅ First error detection – stops when the first reader error is encountered.
✅ Line number reporting – reports the source line where the reader problem was detected.
✅ Problem text output – prints the offending source line for faster troubleshooting.
✅ Reader error message – prints the trapped Visual LISP error message when available.
Result:
🎯 CheckLspFile provides the described AutoCAD or Civil 3D workflow.
