From ab54d9c9f162d07a62004bc0e9b958c345a03c07 Mon Sep 17 00:00:00 2001 From: "C. McEnroe" Date: Mon, 28 Dec 2020 20:06:44 -0500 Subject: Add initial version of hilex hilex is meant to replace hi, based on lex rather than a mess of overlapping regexps. I want to preserve hi's tagging abilities, but that will require some amount of parsing/post-processing, which I'm not sure how to approach yet. Macro lexing for C still needs work, as I want to match strings and comments inside macros. --- bin/hilex/ansi.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 bin/hilex/ansi.c (limited to 'bin/hilex/ansi.c') diff --git a/bin/hilex/ansi.c b/bin/hilex/ansi.c new file mode 100644 index 00000000..5ecd1f2a --- /dev/null +++ b/bin/hilex/ansi.c @@ -0,0 +1,44 @@ +/* Copyright (C) 2020 C.
