The existing code mixes parsing of email header with regular expression and actual code. Extract the parsing code into a new subroutine "parse_header_line()". This improves the code readability and make parse_header_line reusable in other place. "parsed_header_line()" and "filter_body()" could be used for refactoring the part of code which parses the header to prepare the email and send it. In contrast to the previous version it doesn't keep the header order and strip duplicate headers.

I find "$addr_headers_pat" too long that's why I've choose rename it into "$addr_pat", in addition to that, because the variable is in the subroutine "parse_header_line" it does not require to include "headers" in the variable name. git-send-email.perl | 115 +++++++++++++++++++++++++++++++++++----------------- 1 file changed, 77 insertions(+), 38 deletions(-) diff --git a/git-send-email.perl b/git-send-email.perl index 2208dcc21..e6e813041 100755 --- a/git-send-email.perl +++ b/git-send-email.perl @@ -703,57 +703,70 @@ EOT3 do_edit($compose_filename); } - open my $c2, ">", $compose_filename .
