To commit a change in git on the command line, assuming git is installed, the following command is run: [1] git commit -m 'commit message' This is also assuming that the files within the current directory have been staged as such: [2] git add . The above command adds all of the files in the working directory to be staged for the git commit.
Version control systems attach metadata to changesets. Typical metadata includes a description provided by the programmer (a "commit message" in Git lingo), the name of the author, the date of the commit, etc. [9] Unique identifiers are an important part of the metadata which version control systems attach to changesets.
git add [file], which adds a file to git's working directory (files about to be committed). git commit -m [commit message], which commits the files from the current working directory (so they are now part of the repository's history). A .gitignore file may be created in a Git repository as a plain text file.
A committer is an individual who is permitted to modify the source code of a software project, [1] [2] that will be used in the project's official releases. [3] To contribute source code to most large software projects, one must make modifications and then "commit" those changes to a central version control system, such as Git (or CVS).
On many version control systems with atomic multi-change commits, a change list (or CL), change set, update, or patch identifies the set of changes made in a single commit. This can also represent a sequential view of the source code, allowing the examination of source as of any particular changelist ID.
A Darcs patch can contain changes of the following kinds: line changes, file and directory creation and deletion, file and directory moving, word substitution (typically used in code refactoring, for instance rename all occurrences of "foo" to "bar" in a given file). The notion of dependency between patches is defined syntactically.
[1] [2] [3] Git, the world's most popular version control system, [4] is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the [past] ten years". [2]
Refactoring is usually motivated by noticing a code smell. [2] For example, the method at hand may be very long, or it may be a near duplicate of another nearby method. Once recognized, such problems can be addressed by refactoring the source code, or transforming it into a new form that behaves the same as before but that no longer "smells".
