'How to get sha of current git commit from R
Is there a way to get SHA of current GIT commit from R? I need to access it via a function call (not as a hard string).
I have adapted GIT as version control system for analysis, and want to print the SHA on footnote of my intermediate reports (my working drafts, in pdf format, get a life of their own and it is not immediately obvious by looking at them at what moment they were generated; this creates a reproducibility issue).
For reference: I am using R 3.4.1 via R Studio and creating reports via r markdown.
Solution 1:[1]
Install git2r package and then:
> library(git2r)
> r = revparse_single(path,"HEAD")
> sha(r)
[1] "f5bb1f115e9db0c732840298465488e8dfea5032"
It also gives you some other info about the commit too, in other members of the returned object:
> r$author
name: Barry Rowlingson
email: [email protected]
when: 2022-01-12 18:37:14 GMT
These are documented in help(commit), but only sha seems to have an accessor function for it.
