Atharva Raykar a437390310 userdiff: add support for Scheme
Add a diff driver for Scheme-like languages which recognizes top level
and local `define` forms, whether it is a function definition, binding,
syntax definition or a user-defined `define-xyzzy` form.

Also supports R6RS `library` forms, `module` forms along with class and
struct declarations used in Racket (PLT Scheme).

Alternate "def" syntax such as those in Gerbil Scheme are also
supported, like defstruct, defsyntax and so on.

The rationale for picking `define` forms for the hunk headers is because
it is usually the only significant form for defining the structure of
the program, and it is a common pattern for schemers to have local
function definitions to hide their visibility, so it is not only the top
level `define`'s that are of interest. Schemers also extend the language
with macros to provide their own define forms (for example, something
like a `define-test-suite`) which is also captured in the hunk header.

Since it is common practice to extend syntax with variants of a form
like `module+`, `class*` etc, those have been supported as well.

The word regex is a best-effort attempt to conform to R7RS[1] valid
identifiers, symbols and numbers.

Philippe Blain 75c3b6b2e8 userdiff: improve Fortran xfuncname regex
The third part of the Fortran xfuncname regex wants to match the
beginning of a subroutine or function, so it allows for all characters
except `'`, `"` or whitespace before the keyword 'function' or
'subroutine'. This is meant to match the 'recursive', 'elemental' or
'pure' keywords, as well as function return types, and to prevent
matches inside strings.

However, the negated set does not contain the `!` comment character,
so a line with an end-of-line comment containing the keyword 'function' or
'subroutine' followed by another word is mistakenly chosen as a hunk header.

Improve the regex by adding `!` to the negated set.

Ash Holland 09dad9256a userdiff: support Markdown
It's typical to find Markdown documentation alongside source code, and
having better context for documentation changes is useful; see also
commit 69f9c87d4 (userdiff: add support for Fountain documents,
2015-07-21).

The pattern is based on the CommonMark specification 0.29, section 4.2
<https://spec.commonmark.org/> but doesn't match empty headings, as
seeing them in a hunk header is unlikely to be useful.

Only ATX headings are supported, as detecting setext headings would
require printing the line before a pattern matches, or matching a
multiline pattern. The word-diff pattern is the same as the pattern for
HTML, because many Markdown parsers accept inline HTML.

Jeff King f5914f4b6b parse_config_key(): return subsection len as size_t
We return the length to a subset of a string using an "int *"
out-parameter. This is fine most of the time, as we'd expect config keys
to be relatively short, but it could behave oddly if we had a gigantic
config key. A more appropriate type is size_t.

Let's switch over, which lets our callers use size_t as appropriate
(they are bound by our type because they must pass the out-parameter as
a pointer). This is mostly just a cleanup to make it clear this code
handles long strings correctly. In practice, our config parser already
chokes on long key names (because of a similar int/size_t mixup!).

When doing an int/size_t conversion, we have to be careful that nobody
was trying to assign a negative value to the variable. I manually
confirmed that for each case here. They tend to just feed the result to
xmemdupz() or similar; in a few cases I adjusted the parameter types for
helper functions to make sure the size_t is preserved.

Stephen Boyd 8da56a4848 userdiff: fix some corner cases in dts regex
While reviewing some dts diffs recently I noticed that the hunk header
logic was failing to find the containing node. This is because the regex
doesn't consider properties that may span multiple lines, i.e.

	property = <something>,
		   <something_else>;

and it got hung up on comments inside nodes that look like the root node
because they start with '/*'. Add tests for these cases and update the
regex to find them. Maybe detecting the root node is too complicated but
forcing it to be a backslash with any amount of whitespace up to an open
bracket seemed OK. I tried to detect that a comment is in-between the
two parts but I wasn't happy so I just dropped it.

Nguyễn Thái Ngọc Duy 7a400a2c02 attr: remove an implicit dependency on the_index
Make the attr API take an index_state instead of assuming the_index in
attr code. All call sites are converted blindly to keep the patch
simple and retain current behavior. Individual call sites may receive
further updates to use the right index instead of the_index.

There is one ugly temporary workaround added in attr.c that needs some
more explanation.

Commit c24f3abace (apply: file commited with CRLF should roundtrip
diff and apply - 2017-08-19) forces one convert_to_git() call to NOT
read the index at all. But what do you know, we read it anyway by
falling back to the_index. When "istate" from convert_to_git is now
propagated down to read_attr_from_array() we will hit segfault
somewhere inside read_blob_data_from_index.

The right way of dealing with this is to kill "use_index" variable and
only follow "istate" but at this stage we are not ready for that:
while most git_attr_set_direction() calls just passes the_index to be
assigned to use_index, unpack-trees passes a different one which is
used by entry.c code, which has no way to know what index to use if we
delete use_index. So this has to be done later.

Ilya Kantor 9c03caca2c userdiff: fix HTML hunk header regexp
Current HTML header regexp doesn't match headers without attributes.

So it fails to match <h1>...</h1>, while <h1 class="smth">...</h1> matches.

Make attributes optional to fix this.  The regexp is still far from
perfect, but now it at least handles the common case.

Brandon Williams b2141fc1d2 config: don't include config.h by default
Stop including config.h by default in cache.h.  Instead only include
config.h in those files which require use of the config system.

Junio C Hamano 2aef63d31c attr: convert git_check_attrs() callers to use the new API
The remaining callers are all simple "I have N attributes I am
interested in.  I'll ask about them with various paths one by one".

After this step, no caller to git_check_attrs() remains.  After
removing it, we can extend "struct attr_check" struct with data
that can be used in optimizing the query for the specific N
attributes it contains.

Junio C Hamano 7bd18054d2 attr: rename function and struct related to checking attributes
The traditional API to check attributes is to prepare an N-element
array of "struct git_attr_check" and pass N and the array to the
function "git_check_attr()" as arguments.

In preparation to revamp the API to pass a single structure, in
which these N elements are held, rename the type used for these
individual array elements to "struct attr_check_item" and rename
the function to "git_check_attrs()".

William Duclot 0719f3eecd userdiff: add built-in pattern for CSS
CSS is widely used, motivating it being included as a built-in pattern.

It must be noted that the word_regex for CSS (i.e. the regex defining
what is a word in the language) does not consider '.' and '#' characters
(in CSS selectors) to be part of the word. This behavior is documented
by the test t/t4018/css-rule.
The logic behind this behavior is the following: identifiers in CSS
selectors are identifiers in a HTML/XML document. Therefore, the '.'/'#'
character are not part of the identifier, but an indicator of the nature
of the identifier in HTML/XML (class or id). Diffing ".class1" and
".class2" must show that the class name is changed, but we still are
selecting a class.

Logic behind the "pattern" regex is:
    1. reject lines ending with a colon/semicolon (properties)
    2. if a line begins with a name in column 1, pick the whole line

Credits to Johannes Sixt (j6t@kdbg.org) for the pattern regex and most
of the tests.

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 .
