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/exec.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/cmd/rc/exec.h') diff --git a/src/cmd/rc/exec.h b/src/cmd/rc/exec.h index a3a6ae9..78250f1 100644 --- a/src/cmd/rc/exec.h +++ b/src/cmd/rc/exec.h @@ -7,6 +7,7 @@ * code in line with jump around {...} */ +void Xcase(void); void Xmark(void); // Xmark marks stack location for word void Xindex(void); // Xindex void Xlocal(void); // Xlocal(name,val) create local variable, assign value @@ -22,6 +23,7 @@ void Xbang(void); void Xasync(void); void Xbasic(void); // Xbasic(args) run command and wait for result void Xsubshell(void); +void Xsettrue(void); void Xword(void); void Xjoin(void); void Xconcatenate(void); -- cgit v1.2.1
