"I want to understand ancestry references!"

Source: R/exo-revparse.R
exo_revparse.Rd

I want to find the commit ID and message for HEAD~5 and HEAD^^. The tool for that is git rev-parse combined with git log or git show. More on ancestry references: https://git-scm.com/book/be/v2/Git-Tools-Revision-Selection.html#_ancestry_references.

Usage

exo_revparse(parent_path)

Arguments

parent_path

Path where to create the exercise repo

Value

The path to the new project

Workflow

Running the function will create the exercise as a new folder in parent_path. If called from RStudio or Positron, the function will open a new R session in that IDE. If not, the user will need to navigate to the path returned by the function, and launch an R session from there. The new R session will display messages about what challenge to solve, and running the tip() function from that new R session will display additional guiance.

git rev-parse, git log, git show.

Examples

if (FALSE) { # interactive()
parent_path <- withr::local_tempdir()
path <- exo_revparse(parent_path = parent_path)
}
