From 54b8a8918bb63c98a8f58e823033232243647562 Mon Sep 17 00:00:00 2001 From: zinc Date: Wed, 14 Oct 2026 10:39:47 +0000 Subject: zc: add the defer statement defer expr; and defer { ... } register code that runs when the enclosing block ends: at the end of the block, and at return, break and continue that leave it. the tokens are kept at the defer and compiled again at each exit (block_close, body, kw_return, kw_break, kw_continue), newest first, before the block's variables are released, so the analyzer sees a deferred rt.free(p) as the transfer of p where it runs. names mean what they meant at the defer; values are read when it runs. return, break and continue inside a deferred statement are errors, reported once. works in unchecked code and closures (own base per function context). --- examples/learn/34-defer.out | 4 ++++ 1 file changed, 4 insertions(+) create mode 100644 examples/learn/34-defer.out (limited to 'examples/learn/34-defer.out') diff --git a/examples/learn/34-defer.out b/examples/learn/34-defer.out new file mode 100644 index 0000000..284c915 --- /dev/null +++ b/examples/learn/34-defer.out @@ -0,0 +1,4 @@ +0 1 100 0 0 +1 +4 1 100 0 2 +6 100 7 3 -- cgit v1.2.3
