From e9ff1c6fbbbac9ece2604876ab589ac282360446 Mon Sep 17 00:00:00 2001 From: Nicholas Date: Mon, 15 Nov 2021 15:08:03 -0800 Subject: Feat: added if/else branching and switch statement Unsure about my modification to the language. I found the parsing of the case body within switches to be odd - specifically that it parses liberally and then checks that it has case -> cmd structuring while it walks the code. This means the language is more permissive than the semantics. I modified it to be more explicit, but at the cost of having to end each case statement with a semicolon. I wanted a colon, but this is a valid word character and thus will be lexed as part of the word. --- src/cmd/rc/rules.mk | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/cmd/rc/rules.mk') diff --git a/src/cmd/rc/rules.mk b/src/cmd/rc/rules.mk index 76837fc..206c517 100644 --- a/src/cmd/rc/rules.mk +++ b/src/cmd/rc/rules.mk @@ -15,6 +15,7 @@ SRCS_$(d):=\ $(d)/sys.c\ $(d)/wait.c\ $(d)/job.c\ + $(d)/glob.c\ $(d)/exec.c\ $(d)/main.c @@ -23,7 +24,7 @@ BINS_$(d) := $(d)/rc include share/paths.mk $(d)/parse.h $(d)/parse.c: $(d)/syntax.y - yacc --header=$(
