🌸 SYNOPSIS 🌸

::tcl::build-info ?field?

💅 DESCRIPTION 💅

so basically, this command is your lil spy cam into how Tcl was built. like, the receipts. the lore. 🔍

If you don't pass any options at all, it hands you the Tcl patchlevel, then a '+' sign, then the fossil commit-id, and then a list of dot-separated tags. all glued together. iconic behavior honestly.

But if you give it a field, it pulls out just that one field, exactly like described below. 👇

🚨 important bestie: any other field value that isn't mentioned below will always return "0". no exceptions, no drama.

For official Tcl releases, the fields are:

• ::tcl::build-info clang — gives you the clang version number (as 4 digits) if Tcl was compiled with clang, and 0 if it wasn't. 💀
• ::tcl::build-info commit — gives you the fossil commit-id that Tcl was built from. the origin story fr.
