Convert::ASN1 is a perl library for encoding/decoding data using ASN.1 definitions
The ASN.1 parser is not a complete implementation of the ASN.1 specification. It has been built over time and features have been added on an as-needed basis.
The latest release can be found on http://www.cpan.org/ at http://search.cpan.org/dist/Convert-ASN1/
The documentation is at http://search.cpan.org/perldoc?Convert::ASN1
Install with your favorite CPAN install manager, eg
If you do not have cpanm installed you can run
curl -s -L http://cpanmin.us | perl - Convert::ASN1
The preferred method of contribution is by forking a repository on github.
If you are not familiar with working with forked repositories please read http://help.github.com/fork-a-repo/ for details on how to setup your fork.
Try to avoid submitting to the master branch in your fork, it is useful to keep that following the main repository and if I decide to cherry-pick or fixup any commit you submit in a pull request you will have tracking issues later
To start a branch for fixes do the following, assuming you have the origin and upstream remotes setup as in the guide linked to above.
git fetch upstream git checkout -b mybranch upstream/master
this will checkout a new branch called mybranch from the latest code in the master branch of the upstream repository.
Once you have finished push that branch to your origin repository with
git push -u origin HEAD
The -u will setup branch tracking so if you later add more commits a simple
is enough to push those commits.
Once you have pushed the branch to github, send a pull as described at http://help.github.com/send-pull-requests/
The release is developed using Dist::Zilla
you will need to install
once you have the base install of Dist::Zilla run
dzil authordeps --missing | cpanm dzil listdeps --missing | cpanm
If you need to make changes to the parser then you will need to build perl-byacc1.8.2. You can fetch the source from perl-byacc1.8.2.tar.gz
With that built and available in your $PATH as byacc the parser can be compiled with
perl mkparse parser.y lib/Convert/ASN1/parser.pm
