OpenWrt的feeds.conf.default, 是新增一些應用和包的檔案, 看過之後下面解析命令用法
先說# , 這個是註釋用, 不會有人不知道吧
這個檔案主要是由scripts/feeds這個perl指令碼控制著, 貼一個命令的定義

我願稱之為git與svn的結合體
這個主要命令是git svn clone -r HEAD, 參考https://git-scm.com/docs/git-svn
用法:

git clone區別是clone的深度不一樣, src-git-full是全clone, 而src-git的深度為--depth 1src-git-full / src-git-full 儲存的資料夾名 倉庫地址src-git NueXini_Packages https://github.com/NueXini/NueXini_Packages.git;main
# 指定branch
src-git NueXini_Packages https://github.com/NueXini/NueXini_Packages.git;v20220620

# 指定commit
'src-cpy' => {
'init' => "cp -Rf '%s' '%s'",
'update' => "",
'revision' => "echo -n 'local'"},
'src-link' => {
'init' => "ln -s '%s' '%s'",
'update' => "",
'revision' => "echo -n 'local'"},
這兩個命令的唯一區別是src-cpy會複製一份源到feeds目錄, src-link則是ln -s建立一個軟連結, 我個人是比較傾向src-link的, 這樣可以修改原始碼能及時響應.
src-cpy / src-link 儲存的檔名 源目錄 src-link NueXini_Packages package/NueXini_Packages
# 拉取package目錄下的NueXini_Packages目錄
bzr, hg, darcs 一些其他的分散式版本控制系統, 基本很少用到, 可以自行參考命令解釋瞭解使用方法sub usage() {
print <<EOF;
Usage: $0 <command> [options]
Commands:
list [options]: List feeds, their content and revisions (if installed)
Options:
-n : List of feed names.
-s : List of feed names and their URL.
-r <feedname>: List packages of specified feed.
-d <delimiter>: Use specified delimiter to distinguish rows (default: spaces)
-f : List feeds in feeds.conf compatible format (when using -s).
install [options] <package>: Install a package
Options:
-a : Install all packages from all feeds or from the specified feed using the -p option.
-p <feedname>: Prefer this feed when installing packages.
-d <y|m|n>: Set default for newly installed packages.
-f : Install will be forced even if the package exists in core OpenWrt (override)
search [options] <substring>: Search for a package
Options:
-r <feedname>: Only search in this feed
uninstall -a|<package>: Uninstall a package
Options:
-a : Uninstalls all packages.
update -a|<feedname(s)>: Update packages and lists of feeds in feeds.conf .
Options:
-a : Update all feeds listed within feeds.conf. Otherwise the specified feeds will be updated.
-i : Recreate the index only. No feed update from repository is performed.
-f : Force updating feeds even if there are changed, uncommitted files.
clean: Remove downloaded/generated files.

branch與commit的分割是不一樣的branch用的分割符號是;commit用的分割符號是^my ($base_branch, $branch) = split(/;/, $src, 2);
my ($base_commit, $commit) = split(/\^/, $src, 2);
tag就是給commit的hash校驗和取的一個名字，比較直觀，方便記憶和使用
tag就像是一個里程碑一個標誌一個點，branch是一個新的征程一條線；tag是靜態的，branch要向前走；
tag 對應某次 commit, 是一個點，是不可移動的。
branch 對應一系列 commit，是很多點連成的一根線，有一個HEAD 指標，是可以依靠 HEAD 指標移動的。
所以，兩者的區別決定了使用方式，改動程式碼用 branch ,不改動只檢視用 tag。
