Module: Rosette::Core::Commands::WithRef

Included in:
CommitCommand, EnqueueCommitCommand, ExportCommand, RepoSnapshotCommand, RequeueCommitCommand, ShowCommand, SnapshotCommand, StatusCommand, TranslationLookupCommand, WithNonMergeRef
Defined in:
lib/rosette/core/commands/git/with_ref.rb

Overview

Mixin that handles configuration and validation of a git ref or commit id. Meant to be mixed into the classes in Rosette::Core::Commands. Required to be used in combination with WithRepoName.

Examples:

class MyCommand < Rosette::Core::Commands::Command
  include WithRepoName
  include WithRef
end

cmd = MyCommand.new
  .set_repo_name('my_repo')
  .set_ref('master')

cmd.commit_str  # => "master"
cmd.commit_id   # => "67f0e9a60dfe39430b346086f965e6c94a8ddd24"
cmd.valid?      # => true

cmd.set_ref('non_existant_ref')
cmd.valid?    # => false
cmd.messages  # => { commit_str: ["Unable to find commit 'non_existent_ref'"] }

Instance Method Details

#commit_id ⇒ String

Resolves the given git ref or commit id and returns the corresponding commit id. If #set_ref was used to set a git ref (i.e. branch name), this method looks up and returns the corresponding commit id. If #set_commit_id was used to set a commit id, then that commit id is validated and returned.

Returns:

Raises:

  • (Java::OrgEclipseJgitErrors::MissingObjectException, Java::JavaLang::IllegalArgumentException) —

    If either the commit id doesn’t exist or the ref can’t be found.

#set_commit_id(commit_id) ⇒ self

Set the git commit id. Calling this method after #set_ref will overwrite the ref value. In other words, it’s generally a good idea to only call one of #set_commit_id or #set_ref but not both.

Parameters:

  • commit_id (String) —

    The commit id.

Returns:

  • (self)

#set_ref(ref_str) ⇒ self

Set the git ref (i.e. a branch name). Calling this method after #set_commit_id will overwrite the commit id value. In other words, it’s generally a good idea to only call one of #set_commit_id or #set_ref but not both.

Parameters:

  • ref_str (String) —

    The git ref.

Returns:
