Overview

Integrated Mercurial source control

Prerequisites

Note: This extension leverages your machine's Mercurial (hg) installation,
so you need to install Mercurial first.

Features

• Add files and commit from the source control side-bar (i.e. where git normally appears).

• All the basics: commit, add, forget, update, push and pull.

• See changes inline within text editor.

• Interactive log for basic file history and diff.

• Branch, merge heads, merge with branch, resolve + unresolve files.

• Quickly switch branches, push and pull via status bar.

• Supports named-branches or bookmark workflows.

• Automatic incoming/outgoing counters.

• Undo/rollback.

Feedback & Contributing

• Please report any bugs, suggestions or documentation requests via the Github issues (yes, I see the irony).
• Feel free to submit pull requests.

Initialize a new repo

• Just click the Mercurial icon from the source control title area:

Update to a branch/tag/bookmark

• The current branch name is shown in the bottom-left corner.
• Click it to see a list of branches and tags that you can update to.
• When hg.useBookmarks is enabled, this changes to bookmarks.

Settings

hg.enabled { boolean }

• Enables Hg as a source control manager in VS Code.

hg.useBookmarks { boolean }

• Choose between bookmarks vs. named-branches:
  "false" — named-branches mode (default)
  "true" — bookmarks mode

hg.pushPullScope { all | current | default }

• Specifies what to include in Push/Pull operations.
• Depends on the choice of hg.useBookmarks.
• For named-branches mode:   (i.e. hg.useBookmarks = false)
  "all" — all branches / unrestricted (this is the default)
  "current" — only includes changesets for the current branch
  "default" — only includes changesets for the default branch
• For bookmarks mode:   (i.e. hg.useBookmarks = true)
  "all" — all bookmarks / unrestricted (this is the default)
  "current" — only includes changesets for the active bookmark
  "default" — only includes changesets for bookmarks on the default branch

hg.pushPullBranch DEPRECATED { all | current | default }

• Use hg.pushPullScope instead.
• Specifies which branch(es) should be included in Push/Pull operations.
• Included only for backwards compatibility.

hg.autoUpdate { boolean }

• Enables automatic update of working directory to branch/bookmark head after pulling (equivalent to hg pull --update)
  "true" — enabled
  "false" — disabled, manual update/merge required

hg.autoInOut { boolean }

• Enables automatic counting of incoming/outgoing changes.
• When enabled, these show in the status bar.
• Updated every 3 minutes, or whenever a commit/push/pull is done.
• Note: when hg.pushPullBranch is set to "current" or "default" then only the respective branch will be included in the counts.

hg.autoRefresh { boolean }

• Enables automatic refreshing of Source Control tab and badge counter when files within the project change:
  "true" — enabled
  "false" — disabled, manual refresh still available.

hg.countBadge { tracked | all | off }

• Controls the badge counter for Source Control in the activity bar:
  "tracked" — only count changes to tracked files (default).
  "all" — include untracked files in count.
  "off" — no badge counter.

hg.allowPushNewBranches { boolean }

• Overrides the warning that normally occurs when a new branch is pushed:
  "true" — new branches are pushed without warning (default).
  "false" — shows a prompt when new branches are being pushed (e.g hg push --new-branch)

hg.path { string | null }

• Specifies an explicit hg file path to use.
• This should only be used if hg cannot be found automatically.
• The default behaviour is to search for hg in commonly-known install locations and on the PATH.

hg.commandMode

• Controls the method used to communicate with hg.
• There is a slight start-up performance cost with repeatedly running hg commands.
• Running a command server process in the background allows frequently-used commands to run ~10× faster (e.g. cat, status, summary, branch etc.)
• The server feature is still expiremental, and is therefore not the default. "cli" — spawn a new hg process per command (default). "server" — run a command server process  i.e. hg serve --cmdserve
