Detailed Description

Visual Studio's cl.exe requires some massaging to work with Ninja; for example, it emits include information on stderr in a funny format when building with /showIncludes.

This class parses this output.

Member Function Documentation

FilterInputFilename()

bool CLParser::FilterInputFilename ( string  line )

static

Parse a line of cl.exe output and return true if it looks like it's printing an input filename.

This is a heuristic but it appears to be the best we can do. Exposed for testing.

Definition at line 67 of file clparser.cc.

FilterShowIncludes()

string CLParser::FilterShowIncludes ( const string &  line, const string &  deps_prefix  )

static

Parse a line of cl.exe output and extract /showIncludes info.

If a dependency is extracted, returns a nonempty string. Exposed for testing.

Definition at line 42 of file clparser.cc.

Referenced by Parse(), and TEST().

IsSystemInclude()

bool CLParser::IsSystemInclude ( string  path )

static

Return true if a mentioned include file is a system path.

Filtering these out reduces dependency information considerably.

Parse()

bool CLParser::Parse	(	const string &	output,
		const string &	deps_prefix,
		string *	filtered_output,
		string *	err
	)

Parse the full output of cl, filling filtered_output with the text that should be printed (if any).

Returns true on success, or false with err filled. output must not be the same object as filtered_object.
