TCL.SCRIPT

TCL.SCRIPT LOAD script
TCL.SCRIPT EXISTS sha1 [sha1 ...]
TCL.SCRIPT FLUSH [ASYNC | SYNC]

Manage the Tcl script cache used by TCL.EVAL and TCL.EVALSHA. Behavior mirrors SCRIPT, on a cache that is independent of the PUC-Lua (SCRIPT), Luau (LUAU.SCRIPT), and Wren (WREN.SCRIPT) caches.

TCL.SCRIPT LOAD script — cache the script and return its 40-character SHA1 digest. Tcl has no separate compile phase — parse errors normally surface only when a command runs — so LOAD runs info complete to reject the common unbalanced-braces/brackets/quotes case without executing the script. Other errors (an unknown command, a bad argument) still surface at run time.
TCL.SCRIPT EXISTS sha1 … — array of 1/0, one per digest.
TCL.SCRIPT FLUSH — clear the Tcl cache, reply +OK.

Example

> TCL.SCRIPT LOAD "return [string toupper hello]"
"c1a2b3..."

> TCL.SCRIPT EXISTS c1a2b3...
1) (integer) 1

> TCL.SCRIPT LOAD "set x {"
(error) ERR Error compiling script: script is not complete (unbalanced braces, brackets, or quotes)

> TCL.SCRIPT FLUSH
OK
