repo.gitm

  2. URL , required,represent url for the git repository.
  3. Branches , optional,represent local branches for the git repository. the first branch will be the default branch.
  4. Name , optional,represent local name for the git repository. if this is not provided, then try to guess it from the url.
  5. Repositories , optional,represent the git repository has sub git repositories.

branch.gitm

  1. new/develop/master , required,represent the group name of the branches.
  2. gitmA , required,represent local name for the git repository.
  3. new:develop , new is required develop is optional new represent local branch for the git repository. Develop represent the local branch new may be created from the branch develop or the branch origin/develop .

Usage

Warning: All the commands as follows should be executed in the root path. For Scene One, the root path is Project A. For Scene Two, the root path is Project B.

gitm init

  • If repo.gitm does not exist in the root path, try to create it.
  • If branch.gitm does not exist in the root path, try to create it.
  • If .gitignore does not exist in every git repository, try to create it. If sub git repository exist, try to add them name into the file .gitignore.

gitm clone

gitm clone

Read the file repo.gitm in the current directory, and clone every git repository. If the property branches exist, every branch will be checkout. The fisrt branch will be the default branch.

gitm clone https://raw.githubusercontent.com/snowdream/gitm/master/examples/repository/repo.gitm

gitm fetch

gitm fetch

git pull origin branch --progress -v

Branch is the current branch of the git repository.

git push origin branch:branch --progress -v
