visionmedias flavor of binary management, ported for MongoDB.


$ npm install -g m


$ make install

Installing Binaries

Install a few versions, the version given becomes the active mongodb binary once installation is complete.

$ m 2.0.7
$ m 2.2.0-rc2

List installed binaries:

$ m

ο 2.0.7

Use or install the latest official release:

$ m latest

Use or install the stable official release:

$ m stable

Install a custom or patched version of mongodb from a tarball:

$ m custom 2.1.2-me

Removing Binaries

Remove some versions:

$ m rm 2.2.0-rc1

Instead of using rm we can simply use -:

$ m - 2.2.0-rc1

Binary Usage

When running multiple versions of mongodb, we can target them directly by asking m for the binary path:

$ m bin 2.0.7

Execute a script with 2.0.7 regardless of the active version:

$ m use 2.0.7 some.js

with flags:

$ m as 2.0.7 --debug some.js

When installing or changing the active version we might want to run custom scripts:

$ m pre install /path/to/my/script
$ m post install /path/to/script
$ m pre change /path/to/my/script
$ m post change /path/to/script

List all post change hooks:

$ m post change

To remove a pre install hook:

$ m pre install rm /path/to/script

Remove all post install hooks:

$ m post install rm


Output from m --help:

m by default installs mongodb to /usr/local/m/versions, from which it can see what you have currently installed, and activate previously installed versions of mongodb when m <version> is invoked again.

Activated mongodb versions are then installed to the prefix /usr/local, which of course may be altered via the M_PREFIX environment variable.

To alter where m operates simply export M_PREFIX to whatever you prefer.




Yes tj, this is nearly identical to n. Huge thanks!
