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/main.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/cmd/rc/main.c') diff --git a/src/cmd/rc/main.c b/src/cmd/rc/main.c index 2c0aa42..eb83c90 100644 --- a/src/cmd/rc/main.c +++ b/src/cmd/rc/main.c @@ -54,13 +54,14 @@ main(int argc, char *argv[]) { shell.err = openfd(2); + /* yydebug=1; */ initenv(); initpath(); initkeywords(); initshell(); inithistory(); - enablevi(); + /* enablevi(); */ xboot(argc, argv); /* unreachable */ } -- cgit v1.2.1
