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: http://git-scm.com/docs/gitignore + +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. */ +package ignore + +import ( + "io/ioutil" + "os" + "regexp" + "strings" +) + +// An IgnoreParser is an interface which exposes two methods: +// MatchesPath() - Returns true if the path is targeted by the patterns compiled in the GitIgnore structure +type IgnoreParser interface { + IncludesPath(f string) bool + IgnoresPath(f string) bool + MatchesPath(f string) bool +} + +// GitIgnore is a struct which contains a slice of regexp.Regexp +// patterns +type GitIgnore struct { + patterns []*regexp.Regexp // List of regexp patterns which this ignore file applies + negate []bool // List of booleans which determine if the pattern is negated +} + +// This function pretty much attempts to mimic the parsing rules +// listed above at the start of this file +func getPatternFromLine(line string) (*regexp.Regexp, bool) { + // Trim OS-specific carriage returns. + line = strings.TrimRight(line, "\r") + + // Strip comments [Rule 2] + if strings.HasPrefix(line, `#`) { + return nil, false + } + + // Trim string [Rule 3] + // TODO: Handle [Rule 3], when the " " is escaped with a \ + line = strings.Trim(line, " ") + + // Exit for no-ops and return nil which will prevent us from + // appending a pattern against this line + if line == "" { + return nil, false + } + + // TODO: Handle [Rule 4] which negates the match for patterns leading with "!" + negatePattern := false + if line[0] == '!' { + negatePattern = true + line = line[1:] + } + + // Handle [Rule 2, 4], when # or ! is escaped with a \ + // Handle [Rule 4] once we tag negatePattern, strip the leading ! char + if regexp.MustCompile(`^(\#|\!)`).MatchString(line) { + line = line[1:] + } + + // If we encounter a foo/*.blah in a folder, prepend the / char + if regexp.MustCompile(`([^\/+])/.*\*\.`).MatchString(line) && line[0] != '/' { + line = "/" + line + } + + // Handle escaping the "." char + line = regexp.MustCompile(`\.`).ReplaceAllString(line, `\.`) + + magicStar := "#$~" + + // Handle "/**/" usage + if strings.HasPrefix(line, "/**/") { + line = line[1:] + } + line = regexp.MustCompile(`/\*\*/`).ReplaceAllString(line, `(/|/.+/)`) + line = regexp.MustCompile(`\*\*/`).ReplaceAllString(line, `(|.`+magicStar+`/)`) + line = regexp.MustCompile(`/\*\*`).ReplaceAllString(line, `(|/.`+magicStar+`)`) + + // Handle escaping the "*" char + line = regexp.MustCompile(`\\\*`).ReplaceAllString(line, `\`+magicStar) + line = regexp.MustCompile(`\*`).ReplaceAllString(line, `([^/]*)`) + + // Handle escaping the "?" char + line = strings.Replace(line, "?", `\?`, -1) + + line = strings.Replace(line, magicStar, "*", -1) + + // Temporary regex + var expr = "" + if strings.HasSuffix(line, "/") { + expr = line + "(|.*)$" + } else { + expr = line + "(|/.*)$" + } + if strings.HasPrefix(expr, "/") { + expr = "^(|/)" + expr[1:] + } else { + expr = "^(|.*/)" + expr + } + pattern, _ := regexp.Compile(expr) + + return pattern, negatePattern +} + +// Accepts a variadic set of strings, and returns a GitIgnore object which +// converts and appends the lines in the input to regexp.Regexp patterns +// held within the GitIgnore objects "patterns" field +func CompileIgnoreLines(lines ...string) (*GitIgnore, error) { + g := new(GitIgnore) + for _, line := range lines { + pattern, negatePattern := getPatternFromLine(line) + if pattern != nil { + g.patterns = append(g.patterns, pattern) + g.negate = append(g.negate, negatePattern) + } + } + return g, nil +} + +// Accepts a ignore file as the input, parses the lines out of the file +// and invokes the CompileIgnoreLines method +func CompileIgnoreFile(fpath string) (*GitIgnore, error) { + buffer, error := ioutil.ReadFile(fpath) + if error == nil { + s := strings.Split(string(buffer), "\n") + return CompileIgnoreLines(s...) + } + return nil, error +} + +// MatchesPath is an interface function for the IgnoreParser interface. +// It returns true if the given GitIgnore structure would target a given +// path string "f" +func (g GitIgnore) MatchesPath(f string) bool { + // Replace OS-specific path separator. + f = strings.Replace(f, string(os.PathSeparator), "/", -1) + + matchesPath := false + for idx, pattern := range g.patterns { + if pattern.MatchString(f) { + // If this is a regular target (not negated with a gitignore exclude "!" etc) + if !g.negate[idx] { + matchesPath = true + // Negated pattern, and matchesPath is already set + } else if matchesPath { + matchesPath = false + } + } + } + return matchesPath +} |
