To allow access, make sure that the command line clients can be located using the \c{PATH} environment variable. Alternatively, specify the path to the command line client executable in the \uicontrol Command field in the version control system specific tab in \uicontrol Tools > \uicontrol Options > \uicontrol {Version Control}. If authentication is required to access the repository, enter the user credentials in the \uicontrol Username and \uicontrol Password fields. Enter a timeout for version control operations in the \uicontrol Timeout field. For some version control systems, you can specify the maximum number of lines the log can contain in the \uicontrol {Log count} field. After you set up the version control system, use the command line to check that everything works (for example, use the status command). If no issues arise, you should be ready to use the system also from \QC. For more information on using msysGit on Windows, see \l {Using msysGit on Windows}. \section1 Setting Up General Options Select \uicontrol{Tools} > \uicontrol{Options} > \uicontrol{Version Control} > \uicontrol{General} to specify settings for submit messages: \list \li \uicontrol{Wrap submit messages at} limits the line length of a submit message to the specified number of characters. \li \uicontrol{Submit message check script} is a script or program that can be used to perform checks on the submit message before submitting. The submit message is passed in as the script's first parameter. If there is an error, the script should output a message on standard error and return a non-zero exit code. \li \uicontrol{User/alias configuration file} is a text file that lists author names in mailmap format. For each author, you must specify a real name and email address and optionally an alias and a second email address. For example: \code Jon Doe jdoe Hans Mustermann hm \endcode After you specify a file in this field, you can select authors as values of the submit message fields in the \uicontrol Nicknames dialog. \li \uicontrol{User fields configuration file} is a simple text file consisting of lines specifying submit message fields that take authors as values, for example: \code Acked-by: Initial-patch-by: Reported-by: Rubber-stamped-by: Signed-off-by: Tested-by: \endcode After you specify a file in this field, you can add authors as values of the submit message fields when submitting changes. If you also specified a \uicontrol{User/alias configuration file}, you can select authors in the \uicontrol Nicknames dialog. \li \uicontrol{SSH prompt command} specifies an ssh-askpass command that you can use (on Linux) to prompt the user for a password when using SSH. For example, \c ssh-askpass or \c x11-ssh-askpass, depending on the ssh-askpass implementation that you use. \li \uicontrol {Reset VCS Cache} resets the version control system configuration to a state known to \QC after it has been changed from the command line, for example. \endlist \section1 Creating VCS Repositories for New Projects \QC allows you to create repositories for version control systems that support local repository creation, such as Git, Mercurial, or Bazaar. When creating a new project by selecting \uicontrol File > \uicontrol{New File or Project}, you can choose a version control system on the final wizard page. You can also select \uicontrol Tools and then select \uicontrol {Create Repository} in the submenu for the version control system. To import a project that is under version control, choose \uicontrol {File > New File or Project > Project from Version Control} and select the version control system that you use. Follow the instructions of the wizard to import the project. \section1 Using Common Functions The \uicontrol{Tools} menu contains a submenu for each supported version control system. This section describes using the functions that are available for all the supported version control systems. For more information about the additional functions and options available for a particular version control system, see the topic dedicated to it. The \uicontrol{Version Control} output pane displays the commands that are executed, a timestamp, and the relevant output. Select \uicontrol {Window > Output Panes > Version Control} to open the pane. \image qtcreator-vcs-pane.png \section2 Adding Files When you create a new file or a new project, the wizard displays a page asking whether the files should be added to a version control system. This happens when the parent directory or the project is already under version control and the system supports the concept of adding files, for example, Perforce and Subversion. Alternatively, you can add files later by using the version control tool menus. With Git, there is no concept of adding files. Instead, all modified files must be staged for a commit. \section2 Viewing Diff Output All version control systems provide menu options to \e{diff} the current file or project: to compare it with the latest version stored in the repository and to display the differences. In \QC, a diff is displayed in a read-only editor. If the file is accessible, you can double-click on a selected diff chunk and \QC opens an editor displaying the file, scrolled to the line in question. \image qtcreator-vcs-diff.png With Git and Subversion, the diff is displayed side-by-side in a \l{Comparing Files} {diff editor} by default. To use the inline diff view instead, select the \uicontrol {Switch to Text Diff Editor} (1) option from the toolbar. In the inline diff view, you can use context menu commands to apply, revert, stage, and unstage hunks, as well as send them to a code pasting service. \section2 Viewing Versioning History and Change Details Display the versioning history of a file by selecting \uicontrol{Log} or \uicontrol{Filelog}. Typically, the log output contains the date, the commit message, and a change or revision identifier. Click on the identifier to display a description of the change including the diff in the \uicontrol {Git Show} view. \image qtcreator-vcs-show.png Right-clicking on an identifier brings up a context menu that lets you show annotation views of previous versions (see \l{Annotating Files}). With Git you can also choose to cherry-pick or revert a change. \section2 Annotating Files Annotation views are obtained by selecting \uicontrol{Annotate} or \uicontrol{Blame}. Selecting \uicontrol{Annotate} or \uicontrol{Blame} displays the lines of the file prepended by the change identifier they originate from. Clicking on the change identifier shows a detailed description of the change. To show the annotation of a previous version, right-click on the version identifier at the beginning of a line and choose one of the revisions shown at the bottom of the context menu. This allows you to navigate through the history of the file and obtain previous versions of it. It also works for Git and Mercurial using SHA-1. The same context menu is available when right-clicking on a version identifier in the file log view of a single file. \section2 Committing Changes Once you have finished making changes, submit them to the version control system by choosing \uicontrol{Commit} or \uicontrol{Submit}. \QC displays a commit page containing a text editor where you can enter your commit message and a checkable list of modified files to be included. \image qtcreator-vcs-commit.png When you have finished filling out the commit page information, click on \uicontrol{Commit} to start committing. The \uicontrol{Diff Selected Files} button brings up a diff view of the files selected in the file list. Since the commit page is just another editor, you can go back to it by closing the diff view. You can also switch to an open diff view by selecting it in the \uicontrol{Open Documents} pane in the sidebar. \section2 Reverting Changes All supported version control systems support reverting your project to known states. This functionality is generally called \e reverting. The changes discarded depend on the version control system. A version control system can replace the \uicontrol Revert menu option with other options. For more information about reverting changes using Git, see \l {Reverting Changes Using Git}. \section2 Viewing Status You can select \uicontrol{Status} to view the status of the project or repository. \section2 Updating the Working Tree You can select \uicontrol Update to update your working tree with the latest changes from the branch. Some version control systems allow you to choose between updating the current project and updating all projects. With Git, you stash your changes and then pull the changes from the repository. \section2 Deleting Files You can select \uicontrol Delete to delete obsolete files from the repository. With Git, you delete the files from the working tree and then stage the deleted files for a commit. */
