    ignore is a library which returns a new ignorer object which can test against various paths. This is particularly useful when trying to filter files based on a .gitignore document

    The rules for parsing the input file are the same as the ones listed in the Git docs here:

    The summarized version of the same has been copied here:

    1. A blank line matches no files, so it can serve as a separator
       for readability.
    2. A line starting with # serves as a comment. Put a backslash ("\")
       in front of the first hash for patterns that begin with a hash.
    3. Trailing spaces are ignored unless they are quoted with backslash ("\").
    4. An optional prefix "!" which negates the pattern; any matching file
       excluded by a previous pattern will become included again. It is not
       possible to re-include a file if a parent directory of that file is
       excluded. Git doesn’t list excluded directories for performance reasons,
       so any patterns on contained files have no effect, no matter where they
       are defined. Put a backslash ("\") in front of the first "!" for
       patterns that begin with a literal "!", for example, "\!important!.txt".
    5. If the pattern ends with a slash, it is removed for the purpose of the
       following description, but it would only find a match with a directory.
       In other words, foo/ will match a directory foo and paths underneath it,
       but will not match a regular file or a symbolic link foo (this is
       consistent with the way how pathspec works in general in Git).
    6. If the pattern does not contain a slash /, Git treats it as a shell glob
       pattern and checks for a match against the pathname relative to the
       location of the .gitignore file (relative to the toplevel of the work
       tree if not from a .gitignore file).
    7. Otherwise, Git treats the pattern as a shell glob suitable for
       consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the
       pattern will not match a / in the pathname. For example,
       "Documentation/*.html" matches "Documentation/git.html" but not
       "Documentation/ppc/ppc.html" or "tools/perf/Documentation/perf.html".
    8. A leading slash matches the beginning of the pathname. For example,
       "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".
    9. Two consecutive asterisks ("**") in patterns matched against full
       pathname may have special meaning:
        i.   A leading "**" followed by a slash means match in all directories.
             For example, "** /foo" matches file or directory "foo" anywhere,
             the same as pattern "foo". "** /foo/bar" matches file or directory
             "bar" anywhere that is directly under directory "foo".
        ii.  A trailing "/**" matches everything inside. For example, "abc/**"
             matches all files inside directory "abc", relative to the location
             of the .gitignore file, with infinite depth.
        iii. A slash followed by two consecutive asterisks then a slash matches
             zero or more directories. For example, "a/** /b" matches "a/b",
             "a/x/b", "a/x/y/b" and so on.
        iv.  Other consecutive asterisks are considered invalid.

      type GitIgnore

      type GitIgnore struct {
      	// contains filtered or unexported fields

        GitIgnore wraps a list of ignore pattern.

        func CompileIgnoreFile

        func CompileIgnoreFile(fpath string) (*GitIgnore, error)

          CompileIgnoreFile uses an ignore file as the input, parses the lines out of the file and invokes the CompileIgnoreLines method.

          func CompileIgnoreFileAndLines

          func CompileIgnoreFileAndLines(fpath string, lines ...string) (*GitIgnore, error)

            CompileIgnoreFileAndLines accepts a ignore file as the input, parses the lines out of the file and invokes the CompileIgnoreLines method with additional lines.

            func CompileIgnoreLines

            func CompileIgnoreLines(lines ...string) *GitIgnore

              CompileIgnoreLines accepts a variadic set of strings, and returns a GitIgnore instance which converts and appends the lines in the input to regexp.Regexp patterns held within the GitIgnore objects "patterns" field.


              func (*GitIgnore) MatchesPath

              func (gi *GitIgnore) MatchesPath(f string) bool

                MatchesPath returns true if the given GitIgnore structure would target a given path string `f`.

                type IgnoreParser

                type IgnoreParser interface {
                	MatchesPath(f string) bool

                  IgnoreParser is an interface with `MatchesPaths`.
