git-bundle-sha
Retrieve the Git SHA of the latest commit that touched any number of files. Useful in particular with bundling, when you want to identify a collection of files by something like a hash, but tied to something more real (like a Git history.)
Usage
Install using npm:
npm install git-bundle-sha
And then require:
var gitsha = ;
With a list of file paths
;
Without a list (get HEAD SHA)
;
Options
force
Don't read any values from cache (some things, like the submodule list, are cached for performance.) Default = false
.
length
Trim the resulting SHA to a specified length. Default = null
(no trimming.)
Notes
This works by sub-shelling out to a Git process, so your node process must be able to access git. This also means that it is tied to your project directory at the moment.
Questions
Is this submodule-aware?
Yes. If you are using submodules, any file nested under that submodule directory will have a last-modified SHA that corresponds to the commit that last updated the submodule in the parent project.
