536
There are 3 types of identifiers recognized by this lexer:
537
-id_simple: examples of such identifiers are qmake variables and scoped variables
538
at the left of the operator in assignments (like "SOURCES" in "SOURCES+=foo.cpp goo.cpp");
539
-id_list: those are "value list identifiers" at the right side in assignments
540
(like "foo.cpp goo.cpp" in "SOURCES+=foo.cpp goo.cpp");
541
-id_args: function arguments recognized as one identifier
542
(example: ""${QMAKE_FILE} is intended only for Windows!""
543
in "!win32-*:!wince-*:error("${QMAKE_FILE} is intended only for Windows!")" statements).
546
To recognize those identifiers two additional start conditions are used: list and funcargs.
548
@note "Not" operator (!) is recognized as a part of an identifier. Linefeeds passed to
549
the parser as NEWLINE tokens to preserve file structure but whitespaces are stripped
550
so no indentation is preserved by this lexer (and parser).
552
To debug this lexer, put the line below into the next flex file section.
