I'd like to compare notes sometime #7

Chloe, cpan:CXW here. I just found out about this project after being introduced to your work on CRAI by the Rakudo Weekly. I have unknowingly been working on a similar project and would be interested in trading notes sometime, if you're still working on snowflake. I particularly like your use of inline bash to specify build steps. TIMTOWTDI!

My example corresponding to the snowflake README is at https://github.com/hopenbuild/App-hopen/blob/master/eg/003-double-file-double-compile/.hopen.pl . The dataflow is handled by standalone library Data::Hopen, in case that is of any interest to you as a back end for snowflake.

Thanks for reading this rambling! :) Please let me know if you have any interest in chatting, or feel free to close this issue if not.

Note that the inline Bash is just an example, you can use any executable for snowflake-build. :)

An important aspect of the data flow in Snowflake is that it is based on a content-addressable store, so as to minimize rebuilds.

Thanks for pointing me to Data::Hopen, a data flow library may help with the implementation of parallel builds.

Minimizing rebuilds is a Good Thing :) . You also mention caching in the README --- was it long build times that originally triggered you to start writing snowflake?

In my case, hacking cmake files to build things on Cygwin became very painful over time. I wanted to write a build system that would make it easier for downstream to customize builds without having to involve upstream. That was the genesis of hopen.
