From 63f4f9481ebc865b11a06aeecf0c624104d46afd Mon Sep 17 00:00:00 2001 From: Dylan Baker Date: Tue, 16 Oct 2018 10:03:13 -0700 Subject: Add new compiler.get_argument_syntax method Some compilers try very had to pretend they're another compiler (ICC pretends to be GCC and Linux and MacOS, and MSVC on windows), Clang behaves much like GCC, but now also has clang-cl, which behaves like MSVC. This method provides an easy way to determine whether testing for MSVC like arguments `/w1234` or gcc like arguments `-Wfoo` are likely to succeed, without having to check for dozens of compilers and the host operating system, (as you would otherwise have to do with ICC). --- docs/markdown/snippets/compiler_argument_syntax.md | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 docs/markdown/snippets/compiler_argument_syntax.md (limited to 'docs/markdown/snippets') diff --git a/docs/markdown/snippets/compiler_argument_syntax.md b/docs/markdown/snippets/compiler_argument_syntax.md new file mode 100644 index 0000000..6ae32d4 --- /dev/null +++ b/docs/markdown/snippets/compiler_argument_syntax.md @@ -0,0 +1,22 @@ +## new compiler method `get_argument_syntax` + +The compiler object now has `get_argument_syntax` method, which returns a +string value of `gcc`, `msvc`, or an undefined value string value.
