If a documentation file is marked with a `linguist-documentation=false` attribute, include it in language stats. However, make sure that we do *not* include documentation languages as fallback. Added a new test case to exercise the formerly buggy behaviour. Problem discovered while reviewing @KN4CK3R's tests from gitea#29267. Signed-off-by: Gergely Nagy <forgejo@gergo.csillger.hu>

|

//
|
|
// - `.gitattributes` is empty, so `isDetectable.IsFalse()`,
|
|
// `isVendored.IsTrue()`, and `isDocumentation.IsTrue()` will be
|
|
// false for every file, because these are only true if an
|
|
// attribute is explicitly set.
|
|
//
|
|
// - There is `.dot.pas`, which would be considered Pascal source,
|
|
// but it is a dotfile (thus, `enry.IsDotFile()` applies), and as
|
|
// such, is not considered.
|
|
//
|
|
// - `some-file.xml` will be skipped because Enry considers XML
|
|
// configuration, and `enry.IsConfiguration()` will catch it.
|
|
//
|
|
// - `!isVendored.IsFalse()` evaluates to true, so
|
|
// `analyze.isVendor()` will be called on `cpplint.py`, which will
|
|
// be considered vendored, even though both the filename and
|
|
// contents would otherwise make it Python.
|
|
//
|
|
// - `!isDocumentation.IsFalse()` evaluates to true, so
|
|
// `enry.IsDocumentation()` will be called for `docs.md`, and will
|
|
// be considered documentation, thus, skipped.
|
|

|
|
// that is supposed to filter out files early. With two short asserts!
