svg2pdf update

[ejtttje@…]

The svg2pdf 'snapshot' being used is from 2005, and is no longer being developed. (see "out of date" banner on ​http://webcvs.cairographics.org/svg2pdf/)

However, if you follow the link from that banner, there is a newer version from 2007, which was forked out of the cairo test suite. This version is a very thin wrapper about librsvg, which is receiving ongoing maintenance from GNOME. This is a larger dependency tree for svg2pdf, but it works on more modern SVG files.

I will also contact the developer (cworth) to see if he will host a release package that can be downloaded instead of a git clone.

Have you tested that +universal actually works? At first glance I don't see how it could. Also note that the initial revision for a new version should be 0.

Fix revision number and actually build universal now

The svg2pdf author replied to me, and declined to provide a dedicated svg2pdf package because it turns out there is already a 'rsvg-convert' tool bundled with librsvg. I confirmed this is already available in MacPorts, and produces byte-identical output to the svg2pdf update I attached above, but also accepts additional arguments for controlling zoom, background, etc. Considering rsvg-convert is a supported tool of the main librsvg library, it clearly seems to be the preferable route vs. this unmaintained version.

So, I see two options:

1. Convert this svg2pdf port to a dependance on librsvg with a simple wrapper script, e.g.:

   #!/bin/sh
   if [ $# -lt 2 -o "$1" = "-h" -o "$1" = "--help" ] ; then
   	echo "FAIL: usage: $0 input_file.svg output_file.pdf"
   	exit 255;
   fi
   rsvg-convert -f pdf -o "$2" "$1"
   

2. Remove this port, perhaps with some kind of reference or alias to librsvg's tool (I don't think MacPorts has such a thing?)

We do have the "replaced_by" keyword.

Hmm, this ticket is old, we should do something with it.

If we were to drop this port, the rsvg-convert functionality of librsvg isn't as well known, so people might have trouble finding rsvg-convert on their own. Also since librsvg doesn't directly provide a svg2pdf script, using 'replaced_by' isn't 100% appropriate. So I prefer option (a), it will maintain syntactic compatibility with any scripts which are using svg2pdf, yet provide a maintained/modern svg implementation.

I don't know Portfile syntax well enough to know how to make it install the script shown above. Can it be stored directly in svg2pdf/files and then somehow referenced from the Portfile to install it?

How about naming the script rsvg2pdf and adding a note to the svg2pdf port along the lines of "For a more modern alternative install rsvg2pdf, a wrapper for librsvg providing svg2pdf functionality"?

What's the reasoning for installing svg2pdf in ${prefix}/sbin rather than ${prefix}/bin? Shouldn't this be rather placed in bin and marked conflicting with the svg2pdf port?
