so, know there's "literally" fixtures gtest, constructor/destructor , setup/teardown functions execute after each test rather after entire set of tests in fixture . i can think of ways of hacking around this, there built-in support i'm not finding? you can define static methods setuptestcase , teardowntestcase in test fixture class. more information on in googletest wiki . be careful spelling of these static method names.

i switched on sublime text 3 coding haskell in st3 noticed quite odd, syntax highlighting logic guards. as can see, when write way, highlights first guard in white colour , different sign in mix of white/magenta: only when use wrong syntax (with equal sign after argument) displays correctly. does know how fix this? you're using default haskell syntax highlighting. recommend disabling haskell package , installing sublimehaskell . syntax highlighting better, , recognizes things otherwise being "built-in" (it's prelude functions considered built-in). if you're using built-in haskell highlighting, can check it's buggy using ctrl alt shift p shortcut. highlight each guard pipe individually , hit shortcut. in status bar it'll briefly show syntax scope names associated region. first pipe, you'll source.haskell meta.function.type-declaration.haskell , , second you'll source.haskell keyword.operator.haskell . using sublim...

i want split string in 2 parts this: >>> label = ('a1') ['a', '1'] is there method in python? i tried: >>> label = label.split(',') ['a1'] as can see comma not printed. you can use list : >>> label = 'a1' >>> list(label) ['a', '1'] >>> list iterate on string , collect characters new list. also, cannot use str.split here because method designed split on characters/substrings , remove them resulting list. example, 'a b c'.split() split on whitespace , remove characters returned list, ['a', 'b', 'c'] . want break string individual characters while still keeping of them.
