For example, if -you had the following directory structure: - -```bash -grandparent -`-- parent - |-- child1 - `-- child2 -``` - -You could find the children with patterns such as: `**/child*`, -`grandparent/**/child?`, `**/parent/*`, or even just `**` by itself (which will -return all files and directories recursively). - -Bash's globstar is doublestar's inspiration and, as such, works similarly. -Note that the doublestar must appear as a path component by itself. A pattern -such as `/path**` is invalid and will be treated the same as `/path*`, but -`/path*/**` should achieve the desired result. Additionally, `/path/**` will -match all directories and files under the path directory, but `/path/**/` will -only match directories. - -## Installation - -**doublestar** can be installed via `go get`: - -```bash -go get github.com/bmatcuk/doublestar -``` - -To use it in your code, you must import it: - -```go -import "github.com/bmatcuk/doublestar" -``` - -## Usage - -### Match - -```go -func Match(pattern, name string) (bool, error) -``` - -Match returns true if `name` matches the file name `pattern` -([see below](#patterns)). `name` and `pattern` are split on forward slash (`/`) -characters and may be relative or absolute. - -Note: `Match()` is meant to be a drop-in replacement for `path.Match()`. As -such, it always uses `/` as the path separator. If you are writing code that -will run on systems where `/` is not the path separator (such as Windows), you -want to use `PathMatch()` (below) instead. - - -### PathMatch - -```go -func PathMatch(pattern, name string) (bool, error) -``` - -PathMatch returns true if `name` matches the file name `pattern` -([see below](#patterns)). The difference between Match and PathMatch is that -PathMatch will automatically use your system's path separator to split `name` -and `pattern`. - -`PathMatch()` is meant to be a drop-in replacement for `filepath.Match()`. - -### Glob - -```go -func Glob(pattern string) ([]string, error) -``` - -Glob finds all files and directories in the filesystem that match `pattern` -([see below](#patterns)). `pattern` may be relative (to the current working -directory), or absolute. - -`Glob()` is meant to be a drop-in replacement for `filepath.Glob()`. - -### Patterns - -**doublestar** supports the following special terms in the patterns: - -Special Terms | Meaning -------------- | ------- -`*` | matches any sequence of non-path-separators -`**` | matches any sequence of characters, including path separators -`?` | matches any single non-path-separator character -`[class]` | matches any single non-path-separator character against a class of characters ([see below](#character-classes)) -`{alt1,...}` | matches a sequence of characters if one of the comma-separated alternatives matches - -Any character with a special meaning can be escaped with a backslash (`\`). - -#### Character Classes - -Character classes support the following: - -Class | Meaning ----------- | ------- -`[abc]` | matches any single character within the set -`[a-z]` | matches any single character in the range -`[^class]` | matches any single character which does *not* match the class - -### Abstracting the `os` package - -**doublestar** by default uses the `Open`, `Stat`, and `Lstat`, functions and -`PathSeparator` value from the standard library's `os` package. To abstract -this, for example to be able to perform tests of Windows paths on Linux, or to -interoperate with your own filesystem code, it includes the functions `GlobOS` -and `PathMatchOS` which are identical to `Glob` and `PathMatch` except that they -operate on an `OS` interface: - -```go -type OS interface { - Lstat(name string) (os.FileInfo, error) - Open(name string) (*os.File, error) - PathSeparator() rune - Stat(name string) (os.FileInfo, error) -} -``` - -`StandardOS` is a value that implements this interface by calling functions in -the standard library's `os` package. - -## License - -[MIT License](LICENSE) diff --git a/vendor/github.com/bmatcuk/doublestar/doublestar.go b/vendor/github.com/bmatcuk/doublestar/doublestar.go deleted file mode 100644 index 206e01202..000000000 --- a/vendor/github.com/bmatcuk/doublestar/doublestar.go +++ /dev/null @@ -1,684 +0,0 @@ -package doublestar - -import ( - "fmt" - "os" - "path" - "path/filepath" - "sort" - "strings" - "unicode/utf8" -) - -// An OS abstracts functions in the standard library's os package. -type OS interface { - Lstat(name string) (os.FileInfo, error) - Open(name string) (*os.File, error) - PathSeparator() rune - Stat(name string) (os.FileInfo, error) -} - -// StandardOS is a value that implements the OS interface by calling functions -// in the standard libray's os package. -var StandardOS OS = standardOS{} - -// A standardOS implements OS by calling functions in the standard library's os -// package. -type standardOS struct{} - -func (standardOS) Lstat(name string) (os.FileInfo, error) { return os.Lstat(name) } -func (standardOS) Open(name string) (*os.File, error) { return os.Open(name) } -func (standardOS) PathSeparator() rune { return os.PathSeparator } -func (standardOS) Stat(name string) (os.FileInfo, error) { return os.Stat(name) } - -// ErrBadPattern indicates a pattern was malformed. -var ErrBadPattern = path.ErrBadPattern - -// Split a path on the given separator, respecting escaping. -func splitPathOnSeparator(path string, separator rune) (ret []string) { - idx := 0 - if separator == '\\' { - // if the separator is '\\', then we can just split... - ret = strings.Split(path, string(separator)) - idx = len(ret) - } else { - // otherwise, we need to be careful of situations where the separator was escaped - cnt := strings.Count(path, string(separator)) - if cnt == 0 { - return []string{path} - } - - ret = make([]string, cnt+1) - pathlen := len(path) - separatorLen := utf8.RuneLen(separator) - emptyEnd := false - for start := 0; start < pathlen; { - end := indexRuneWithEscaping(path[start:], separator) - if end == -1 { - emptyEnd = false - end = pathlen - } else { - emptyEnd = true - end += start - } - ret[idx] = path[start:end] - start = end + separatorLen - idx++ - } - - // If the last rune is a path separator, we need to append an empty string to - // represent the last, empty path component.
