Zoë Blade	69f9c87d46	userdiff: add support for Fountain documents Add support for Fountain, a plain text screenplay format. Git facilitates not just programming specifically, but creative writing in general, so it makes sense to also support other plain text documents besides source code. In the structure of a screenplay specifically, scenes are roughly analogous to functions, in the sense that it makes your job easier if you can see which ones were changed in a given range of patches. More information about the Fountain format can be found on its official website, at http://fountain.io .

Johannes Sixt	8a2e8da367	userdiff: have 'cpp' hunk header pattern catch more C++ anchor points The hunk header pattern 'cpp' is intended for C and C++ source code, but it is actually not particularly useful for the latter, and even misses some use-cases for the former. The parts of the pattern have the following flaws: - The first part matches an identifier followed immediately by a colon and arbitrary text and is intended to reject goto labels and C++ access specifiers (public, private, protected). But this pattern also rejects C++ constructs, which look like this: MyClass::MyClass() MyClass::~MyClass() MyClass::Item MyClass::Find(... - The second part matches an identifier followed by a list of qualified names (i.e. identifiers separated by the C++ scope operator '::') separated by space or '' followed by an opening parenthesis (with space between the tokens). It matches function declarations like struct item get_head(... int Outer::Inner::Func(... Since the pattern requires at least two identifiers, GNU-style function definitions are ignored: void func(... Moreover, since the pattern does not allow punctuation other than '', the following C++ constructs are not recognized: . template definitions: template<class T> int func(T arg) . functions returning references: const string& get_message() . functions returning templated types: vector<int> foo() . operator definitions: Value operator+(Value l, Value r) - The third part of the pattern finally matches compound definitions. But it forgets about unions and namespaces, and also skips single-line definitions struct random_iterator_tag {}; because no semicolon can occur on the line. Change the first pattern to require a colon at the end of the line (except for trailing space and comments), so that it does not reject constructor or destructor definitions. Notice that all interesting anchor points begin with an identifier or keyword. But since there is a large variety of syntactical constructs after the first "word", the simplest is to require only this word and accept everything else. Therefore, this boils down to a line that begins with a letter or underscore (optionally preceded by the C++ scope operator '::' to accept functions returning a type anchored at the global namespace). Replace the second and third part by a single pattern that picks such a line. This has the following desirable consequence: - All constructs mentioned above are recognized. and the following likely desirable consequences: - Definitions of global variables and typedefs are recognized: int num_entries = 0; extern const char help_text; typedef basic_string<wchar_t> wstring; - Commonly used marco-ized boilerplate code is recognized: BEGIN_MESSAGE_MAP(CCanvas,CWnd) Q_DECLARE_METATYPE(MyStruct) PATTERNS("tex",...) (The last one is from this very patch.) but also the following possibly undesirable consequence: - When a label is not on a line by itself (except for a comment) it is no longer rejected, but can appear as a hunk header if it occurs at the beginning of a line: next:; IMO, the benefits of the change outweigh the (possible) regressions by a large margin.

Johannes Sixt	f1b75fbaf1	t4018: convert custom pattern test to the new infrastructure For the test case "matches to end of line", extend the pattern by a few wildcards so that the pattern captures the "RIGHT" token, which is needed for verification, without mentioning it in the pattern.

Johannes Sixt	2d08413ba1	t4018: convert perl pattern tests to the new infrastructure There is one subtlety: The old test case 'perl pattern gets full line of POD header' does not have its own new test case, but the feature is tested nevertheless by placing the RIGHT tag at the end of the expected hunk header in t4018/perl-skip-sub-in-pod.

Johannes Sixt	bfa7d01413	t4018: an infrastructure to test hunk headers Add an infrastructure that simplifies adding new tests of the hunk header regular expressions. To add new tests, a file with the syntax to test can be dropped in the directory t4018. The README file explains how a test file must contain; the README itself tests the default behavior.
