2019-08-21userdiff: add a builtin pattern for dts filesStephen Boyd
The Linux kernel receives many patches to the devicetree files each release. The hunk header for those patches typically show nothing, making it difficult to figure out what node is being modified without applying the patch or opening the file and seeking to the context. Let's add a builtin 'dts' pattern to git so that users can get better diff output on dts files when they use the diff=dts driver. The regex has been constructed based on the spec at[1] and with some help from Johannes Sixt.

2016-06-03userdiff: add built-in pattern for CSSWilliam Duclot
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 ( for the pattern regex and most of the tests.

2011-01-18t4034: bulk verify builtin word regex sanityThomas Rast
The builtin word regexes should be tested with some simple examples against simple issues. Do this in bulk. Mainly due to a lack of language knowledge and inspiration, most of the test cases (cpp, csharp, java, objc, pascal, php, python, ruby) are directly based off a C operator precedence table to verify that all operators are split correctly. This means that they are probably incomplete or inaccurate except for 'cpp' itself. Still, they are good enough to already have uncovered a typo in the python and ruby patterns. 'fortran' is based on my anecdotal knowledge of the DO10I parsing rules, and thus probably useless. The rest (bibtex, html, tex) are an ad-hoc test of what I consider important splits in those languages. Signed-off-by: Thomas Rast <> Signed-off-by: Jonathan Nieder <> Signed-off-by: Junio C Hamano <>
