I got about 90% of the way to having a working ruby single-file executable builder which used objcopy to embed a sqlite database of the source files into an MRI build. Then YARV happened and the ruby build chain changed just enough that I needed to throw it out and start again.

Every now and again I ponder having another go with mruby...

FWIW, this is roughly how Tclkits work in the Tcl world. Although by default they use a Metakit database instead of SQLite.

Currently they append the database to the end of the executable, which has some problems and I'm working to make including it in the image more standardized as part of XVFS [0].

The image background on that webpage is extremely distracting

Make your browser width narrow, and it drops to the bottom. Not that you should have to :)

thanks
