* Support glob with doublestar for path conditions * Update docs and pipeline

Upgrading from v3 to v4
v4 is a complete rewrite with a focus on performance. Additionally, doublestar has been updated to use the new io/fs package for filesystem access. As a result, it is only supported by golang v1.16+.
Match()
and PathMatch()
mostly did not change, besides big performance
improvements. Their API is the same. However, note the following corner cases:
- In previous versions of doublestar,
PathMatch()
could accept patterns that used either platform-specific path separators, or/
. This was undocumented and didn't matchfilepath.Match()
. In v4, bothpattern
andname
must be using appropriate path separators for the platform. You can usefilepath.FromSlash()
to change/
to platform-specific separators if you aren't sure. - In previous versions of doublestar, a pattern such as
path/to/a/**
would not matchpath/to/a
. In v4, this pattern will match because ifa
was a directory,Glob()
would return it. In other words, the following returns true:Match("path/to/a/**", "path/to/a")
Glob()
changed from using a doublestar-specific filesystem abstraction (the
OS
interface) to the io/fs package. As a result, it now takes a fs.FS
as
its first argument. This change has a couple ramifications:
- Like
io/fs.Glob
,pattern
must use a/
as path separator, even on platforms that use something else. You can usefilepath.ToSlash()
on your patterns if you aren't sure. - Patterns that contain
/./
or/../
are invalid. The io/fs package rejects them, returning an IO error. SinceGlob()
ignores IO errors, it'll end up being silently rejected. You can runpath.Clean()
to ensure they are removed from the pattern.
v4 also added a GlobWalk()
function that is slightly more performant than
Glob()
if you just need to iterate over the results and don't need a string
slice. You also get fs.DirEntry
objects for each result, and can quit early
if your callback returns an error.
Upgrading from v2 to v3
v3 introduced using !
to negate character classes, in addition to ^
. If any
of your patterns include a character class that starts with an exclamation mark
(ie, [!...]
), you'll need to update the pattern to escape or move the
exclamation mark. Note that, like the caret (^
), it only negates the
character class if it is the first character in the character class.
Upgrading from v1 to v2
The change from v1 to v2 was fairly minor: the return type of the Open
method
on the OS
interface was changed from *os.File
to File
, a new interface
exported by doublestar. The new File
interface only defines the functionality
doublestar actually needs (io.Closer
and Readdir
), making it easier to use
doublestar with go-billy, afero, or something similar. If you were using
this functionality, updating should be as easy as updating Open's
return
type, since os.File
already implements doublestar.File
.
If you weren't using this functionality, updating should be as easy as changing your dependencies to point to v2.
