Perhaps by using %an etc., line numbers and --sq-quote:
$ git rev-list --no-walk --date=raw --format="%an%n%ae%n%ad" --encoding=UTF-8 HEAD |
while read -r s; do git rev-parse --sq-quote "$s"; done |
sed -n -e '2s/^ /GIT_AUTHOR_NAME=/p' -e '3s/^ /GIT_AUTHOR_EMAIL=/p' -e '4s/^ /GIT_AUTHOR_DATE=/p'
GIT_AUTHOR_NAME='Thom'\''as Ràst'
GIT_AUTHOR_EMAIL='trast@xxxxxxxxxxx'
GIT_AUTHOR_DATE='1330935546 +0100'
This is for a commit where I deliberately mangled my author line to make
an interesting example, as in
$ git cat-file commit HEAD | grep ^author
author Thom'as Ràst <trast@xxxxxxxxxxx> 1330935546 +0100
I tried doing the quoting inside sed instead of the while...rev-parse
--sq-quote, but it made my head hurt.
