When GIT variable is empty $imgpath can start with //

[ahendriksen]

Hi,

Happy user of gitdown here. I don't use for a github project though. I use it on gitlab.

When I insert a

[diagram]
---->
[/diagram/

block, I want the url to be as follows (I guess gitlab image inclusion uses different urls)

<img src="images/README_1.png" alt="1">

When I set branch and prebranch to empty

.set BRANCH=
.set PREBRANCH=

I get instead:

<img src="//images/README_1.png" alt="1">

I was able to fix it by removing any slashed in front of the final url as follows:

diff --git a/bin/gitdown b/bin/gitdown
index 653d092..9bbabd9 100755
--- a/bin/gitdown
+++ b/bin/gitdown

             $imgpath =~ s|(?<!:)/+|/|g;

             my $subpath .= "$symbols{PREBRANCH}/$symbols{BRANCH}/$symbols{SUBDIR}/images/";
             # remove starting /
             $subpath =~ s|^/||;
             # remove double /
             $subpath =~ s|/+|/|g;
             $imgpath .= $subpath;

         }
         elsif (/^\.toc(\s+([1-9]))?/) {
             #   Determine top level in text after .toc

I am sorry that this is not a 'pull request'. I am not well acquainted with github..
