From 2e81f599a0323e2025883bc1375bf438d1406733 Mon Sep 17 00:00:00 2001 From: Paul Buetow Date: Thu, 19 Feb 2026 10:13:51 +0200 Subject: Implement function named arguments, ret, and multiple return values - Add FuncDef struct to symbol.h/symbol.c: holds body token list, strdup'd param names, and param count; replaces the bare List* that SYM_FUNCTION used to store; funcdef_delete frees param strings and body list (tokens are GC-managed) - Add CONTROL_RET to ControlType so ret can propagate cleanly through the interpreter's control-flow stack - Update _func_decl to parse optional (p1, p2, ...) param list and store a FuncDef* instead of a raw List* - Implement case TT_RET in _control: clears intermediate stack values, evaluates comma-separated return expressions, sets CONTROL_RET - Propagate CONTROL_RET in all loop bodies (while/until, loop, do) without clearing it; while/until rescues return values from the temporary condition stack before it is destroyed - Update _term call site to support parenthesised func(arg1, arg2) syntax alongside the existing no-parens style for backward compat - Modify interpret_subprocess to merge the sub's stack into the parent when CONTROL_RET is active so return values survive teardown - Update function_process_self_defined SYM_FUNCTION case to pop and bind named args, run the body, then clear CONTROL_RET - Add -D_POSIX_C_SOURCE=200809L to Makefile CFLAGS for strdup under -std=c99 -pedantic - Add examples/func_args_ret.fy covering zero-arg, single-arg, two-arg, conditional ret, multiple return values, and old-style no-parens backward compat Co-Authored-By: Claude Sonnet 4.6 --- docs/help.txt | 2 +- docs/stats.txt | 6 +++--- docs/version.txt | 2 +- 3 files changed, 5 insertions(+), 5 deletions(-) (limited to 'docs') diff --git a/docs/help.txt b/docs/help.txt index 37ccbb1..481c057 100644 --- a/docs/help.txt +++ b/docs/help.txt @@ -1,4 +1,4 @@ -Fype Superalpha Build 9673 +Fype Superalpha Build 9676 (c) Paul C.
