Mercurial OnRemote Extension

Project description

Execute some Mercurial command on remote repository (ssh/local repositories only).

1 Example

My two main use cases:

  • update remote directory after pushing:

    hg push staging
    hg onremote staging update -r tip
  • check status and possibly commit in remote directory:

    hg onremote rhdevel status
    hg onremote rhdevel commit -m 'Forgotten typo'

In those examples staging and rhdevel are remote paths, mapped to urls like ssh:// (local paths work too).

Explicit path works too, but is much less handy:

hg onremote ssh://   status

2 Arguments

General command syntax:

hg onremote «remote» «command» «arguments»

where «remote» is remote repository alias or path, and remaining arguments constitute normal mercurial command.

Option --ssh can be used just like with push or pull:

hg onremote --ssh /custom/ssh staging status

3 How does it work

The extension simply resolves the specified path, and:

  • if it maps to local directory, executes hg --cwd that/directory «command» «arguments»

  • if it maps to ssh path, executes ssh that/machine hg --cwd that/directory «command» «arguments»

  • elsewhere (http or other remote) it refuses to work.

There is nothing particularly magical, the extension is intended to save some keystrokes and avoid flow interruption (I wrote it mainly to stop writing various push and update shell scripts).

4 Configuration

There is currently no dedicated configuration.

Standard mercurial settings are used to decide how to call ssh and which remote command to call to spawn Mercurial (see ssh and remotecmd settings in [ui] section). This way onremote uses the same ssh command which is used by hg push and hg pull, and the same mercurial name.

5 Problems and limitations

Interactive commands may fail to work properly due to lack of fully working console. I recommend avoiding commands which trigger interactive prompts or editor spawns. If you try hg onremote commit add -m "Some message".

6 Installation

Mercurial ≥ 3.4 is required (attempts to run on older version will result in crashes) and Mercurial ≥ 4.5 is strongly recommended (versions 3.4-4.4 involve some hacks which may fail for more complicated arguments).

6.1 Linux/Unix (from PyPI)

If you have working pip or easy_install:

pip install --user mercurial_on_remote

or maybe:

sudo pip install mercurial_on_remote

(or use easy_install instead of pip). Then activate by:

mercurial_on_remote =

To upgrade, repeat the same command with --upgrade option, for example:

pip install --user --upgrade mercurial_on_remote

6.2 Linux/Unix (from source)

If you don’t have pip, or wish to follow development more closely:

  • clone both this repository and mercurial_extension_utils and put them in the same directory, for example:

    cd ~/sources
    hg clone
    hg clone
  • update to newest tags,

  • activate by:

    mercurial_on_remote = ~/sources/mercurial-on_remote/

To upgrade, pull and update.

See mercurial_extension_utils for longer description of this kind of installation.

6.3 Windows

If you have any Python installed, you may install with pip:

pip install mercurial_on_remote

Still, as Mercurial (whether taken from TortoiseHg, or own package) uses it’s own bundled Python, you must activate by specifying the path:

mercurial_on_remote = C:/Python27/Lib/site-packages/
;; Or wherever pip installed it

To upgrade to new version:

pip --upgrade mercurial_on_remote

If you don’t have any Python, clone repositories:

cd c:\hgplugins
hg clone
hg clone

update to tagged versions and activate by path:

mercurial_on_remote = C:/hgplugins/mercurial-on_remote/
;; Or wherever you cloned

See mercurial_extension_utils documentation for more details on Windows installation.
