From: Raphael Moll Date: Mon, 7 May 2012 23:16:46 +0000 (-0700) Subject: Support a new ANDROID_AAPT_IGNORE env var. X-Git-Url: https://git.saurik.com/android/aapt.git/commitdiff_plain/7b055f4f9c266cf8c50488db7086cc2e168113fd Support a new ANDROID_AAPT_IGNORE env var. AAPT has a fixed built-in list of files and directories to ignore when parsing resource files. Over the years we always had developers requiring specific patterns. If the env var ANDROID_AAPT_IGNORE is set, it is parsed to find which file/directory patterns to ignore. Otherwise a default is used that matches the current behavior. Added a command-line option for it: aapt di --ignore-assets "foo*:*.blah" SDK Bug: 5343 24067 Change-Id: Ia4caa2a8188c8c1df143f884e459b8182645995f --- diff --git a/AaptAssets.cpp b/AaptAssets.cpp index 3d6537a..eba77c2 100644 --- a/AaptAssets.cpp +++ b/AaptAssets.cpp @@ -56,55 +56,92 @@ static bool validateFileName(const char* fileName) return true; } +// The default to use if no other ignore pattern is defined. +const char * const gDefaultIgnoreAssets = + "!.svn:!.git:.*:_*:!CVS:!thumbs.db:!picasa.ini:!*.scc:*~"; +// The ignore pattern that can be passed via --ignore-assets in Main.cpp +const char * gUserIgnoreAssets = NULL; + static bool isHidden(const char *root, const char *path) { - const char *ext = NULL; - const char *type = NULL; - - // Skip all hidden files. - if (path[0] == '.') { - // Skip ., .. and .svn but don't chatter about it. - if (strcmp(path, ".") == 0 - || strcmp(path, "..") == 0 - || strcmp(path, ".svn") == 0) { - return true; - } - type = "hidden"; - } else if (path[0] == '_') { - // skip directories starting with _ (don't chatter about it) - String8 subdirName(root); - subdirName.appendPath(path); - if (getFileType(subdirName.string()) == kFileTypeDirectory) { - return true; - } - } else if (strcmp(path, "CVS") == 0) { - // Skip CVS but don't chatter about it. - return true; - } else if (strcasecmp(path, "thumbs.db") == 0 - || strcasecmp(path, "picasa.ini") == 0) { - // Skip suspected image indexes files. - type = "index"; - } else if (path[strlen(path)-1] == '~') { - // Skip suspected emacs backup files. - type = "backup"; - } else if ((ext = strrchr(path, '.')) != NULL && strcmp(ext, ".scc") == 0) { - // Skip VisualSourceSafe files and don't chatter about it + // Patterns syntax: + // - Delimiter is : + // - Entry can start with the flag ! to avoid printing a warning + // about the file being ignored. + // - Entry can have the flag "" to match only directories + // or to match only files.
