How about this?
static boolean looksLikeGit(File dir) {
if (looksLikeSvn(dir)) {
// Prefer svn to git.
return false;
}
File gitDir = findGitDir(dir);
return gitDir != null && new File(gitDir, "index").isFile();
}
static File findGitDir(File dir) {
File ret;
// try $GIT_DIR
// is there any point in worrying about SecurityExceptions here?
// if this code lacks the ability to access $GIT_DIR, it would
// maybe make sense to fall back on the default below.
String gitDir = System.getenv("GIT_DIR");
if (gitDir != null) {
ret = new File(gitDir).getAbsoluteFile();
if (ret.isDirectory()) {
return ret;
}
}
// try searching for a .git at or above dir
dir = dir.getAbsoluteFile();
while (dir != null) {
ret = new File(ret, ".git");
if (ret.isDirectory()) {
return ret;
}
dir = dir.getParentFile();
}
return null;
}
That was typed directly into email and I haven't written any Java in
half a year, so at least compile it before doing anything serious.
Also, it could probably do with a refactoring but that's a real pain
in a text area.
