SHA1 Utilities

Usage

trim_sha(sha)

is_sha(sha)

git_current_sha()

Arguments

sha

character(n). The commit secure hash algorithm (SHA-1). If NULL, typically points to the most recent commit on the current branch.

Value

trim_sha(): character(1). The trimmed sha. If sha is not a SHA1 hash, the identical string unchanged.

is_sha(): logical(1). If sha matches the SHA1 expected pattern.

git_current_sha(): character(1). The sha of the current commit.

Functions

• trim_sha(): trims the SHA-1 hash from the default full length to the human-readable short version.

• is_sha(): determines whether strings to be tested are a SHA1 hash via regular expression ("^[a-f0-9]{5,40}$") match.

• git_current_sha(): gets the current (most recent commit) SHA.
