* Allow CustomTarget's to be indexedDylan Baker2017-09-271-4/+6
| | | | | | | | | | | This allows a CustomTarget to be indexed, and the resulting indexed value (a CustomTargetIndex type), to be used as a source in other targets. This will confer a dependency on the original target, but only inserts the source file returning by index the original target's outputs. This can allow a CustomTarget that creates both a header and a code file to have it's outputs split, for example. Fixes #1470
* str.split() can now take a positional argumentNirbheek Chauhan2017-09-121-8/+19
| | | | | | | All the specified characters in the specified argument will be stripped. If unspecified, the old behaviour is used. Includes tests.

* | Improve "Passed invalid keyword argument" warning.Jehan2017-07-021-1/+1
|/ | | | | | | | | I got this warning on a build: > WARNING: Passed invalid keyword argument preset. This will become a hard error in the future. I had to grep in meson code to understand that "preset" was the name of the invalid argument. This is not obvious at all depending on the argument name (here it looked like it was about argument presets). Let's make it clearer by putting it in quotes.

| | | | | The result of this method is always a "native" object, and code coverage (plus a manual inspection) shows that this conversion is never done.
* Don't use len() to test emptiness vs not emptinessDylan Baker2017-05-021-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Meson has a common pattern of using 'if len(foo) == 0:' or 'if len(foo) != 0:', however, this is a common anti-pattern in python. Instead tests for emptiness/non-emptiness should be done with a simple 'if foo:' or 'if not foo:' Consider the following: >>> import timeit >>> timeit.timeit('if len([]) == 0: pass') 0.10730923599840025 >>> timeit.timeit('if not []: pass') 0.030033907998586074 >>> timeit.timeit('if len(['a', 'b', 'c', 'd']) == 0: pass') 0.1154778649979562 >>> timeit.timeit("if not ['a', 'b', 'c', 'd']: pass") 0.08259823200205574 >>> timeit.timeit('if len("") == 0: pass') 0.089759664999292 >>> timeit.timeit('if not "": pass') 0.02340641999762738 >>> timeit.timeit('if len("foo") == 0: pass') 0.08848102600313723 >>> timeit.timeit('if not "foo": pass') 0.04032287199879647 And for the one additional case of 'if len(foo.strip()) == 0', which can be replaced with 'if not foo.isspace()' >>> timeit.timeit('if len(" ".strip()) == 0: pass') 0.15294511600222904 >>> timeit.timeit('if " ".isspace(): pass') 0.09413968399894657 >>> timeit.timeit('if len(" abc".strip()) == 0: pass') 0.2023209120015963 >>> timeit.timeit('if " abc".isspace(): pass') 0.09571301700270851 In other words, it's always a win to not use len(), when you don't actually want to check the length.
* Fix an uninitialized variable access error.Hemmo Nieminen2017-02-021-0/+2
| | | | | | | | | | | | | | | | | To reproduce, one could write: foo = files('foo.c') foo[0].path() and get: Traceback (most recent call last): [snip] File "/home/trhd/Projects/meson/mesonbuild/interpreterbase.py", line 398, in method_call raise InvalidArguments('Variable "%s" is not callable.' % object_name) UnboundLocalError: local variable 'object_name' referenced before assignment Fix this by handling file objects separately.
