WebStorm 8.0.0 Web Help

The Mercurial integration with WebStorm provides the possibility to switch update the repository's working directory to the specified changeset or a specific line of development. Changesets can be identified by their hashes or by previously assigned tag identifiers.

On this page:

You can update a named branch or a bookmark to another named branch, another bookmark, or a specific changeset identified by a tag or a revision number.

  • Updating a named branch or a bookmark to another named branch or bookmark means updating to its head.

    Updating to named branches and bookmarks can be invoked through the menu item VCS | Mercurial | Update to, which opens the Mercurial-specific Switch Working Directory dialog box of from the Branches pop-up list.

  • Updating a named branch or a bookmark to a changeset means updating the branch head to the specified changeset. A changeset can be identified either by a revision number or a tag, see http://mercurial.selenic.com/wiki/Tag?highlight=28\bCategoryGlossary\b29.

    Updating a named branch or a bookmark to a specific changeset can be invoked only through VCS | Mercurial | Update to.

By default, Mercurial requires that before update the current working directory should be clean, that is, it should not contain any uncommitted changes. Otherwise the update operation fails and WebStorm shows the corresponding error message. The message also recommends that you clean the current working directory by running the hg update <target branch, bookmark, or changeset> -C to discard the uncommitted changes.

If your current working copy is not clean, you can either commit the changes or shelve them as described in Shelving and Unshelving Changes. WebStorm provides the possibility to discard any uncommitted changes when the update operation is already invoked. This option is available only in the Mercurial-specific Switch Working Directory dialog box.

Opening the Branches pop-up list

To open the Branches pop-up list, do one of the following:

  • On the Status bar, click the name of the current named branch in the dedicated hg area.

  • On the main menu, choose VCS | Mercurial | Branches.
  • On the context menu of the Editor or Changes tool window, choose Mercurial | Branches.
Switching to another named branch or bookmark

Updating a named branch or a bookmark to another named branch or bookmark means updating to its head.

  1. Make sure, your current working directory is clean, that is, it does not contain any uncommitted changes. Commit or shelve the changes, if any.

    If you invoke update through the Switch Working Directory dialog box, you can also prevent conflicts by having any uncommitted changes discarded.

  2. Invoke update by doing one of the following:
    • In the Branches pop-up list, click the name of the branch or bookmark to update to, then choose Update to on the pop-up menu:
    • Choose VCS | Mercurial | Update to on the main menu or Mercurial | Update to on the context menu of the Editor.

      In the Switch Working Directory dialog box that opens:

      1. Choose the target repository from the Repository drop-down list which shows all the Mercurial repositories available under the current project root.
      2. Choose the Branch or Bookmark option and choose the named branch or bookmark to update the current working directory to.
      3. To prevent failures during update if the current working directory is not clean, select the Overwrite locally modified files (no backup) check box. The uncommitted changes will be discarded.

Switching to another changeset
  1. Make sure, your current working directory is clean, that is, it does not contain any uncommitted changes. Commit or shelve the changes, if any.

    If you invoke update through the Switch Working Directory dialog box, you can also prevent conflicts by having any uncommitted changes discarded.

  2. Invoke update by doing one of the following:
    • In the Branches pop-up list, click the name of the branch or bookmark to update to, then choose Update to on the pop-up menu:
    • Choose VCS | Mercurial | Update to on the main menu or Mercurial | Update to on the context menu of the Editor.

      In the Switch Working Directory dialog box that opens:

      1. Choose the target repository from the Repository drop-down list which shows all the Mercurial repositories available under the current project root.
      2. Choose the Branch or Bookmark option and choose the named branch or bookmark to update the current working directory to.
      3. To prevent failures during update if the current working directory is not clean, select the Overwrite locally modified files (no backup) check box. The uncommitted changes will be discarded.

  3. Resolve conflicts. As soon as a conflict takes place, the Files Merged with Conflicts dialog box opens with a list of conflicting files. Use the controls of the dialog box to resolve the problems:
    • To have the version of the current working directory preserved, click Accept Yours.
    • To have the version of the branch you are merging with preserved, click Accept Theirs.
    • To resolve the conflicts manually, click Merge and use the Conflict Resolution Tool, as described in Resolving Conflicts.

    If no conflicts arise during update, the operation passes silently and the update log is shown in the Version Control tool window.
