This is a good thing!
All good applications are just wrappers around a library.

I'm sort of up this alley with my $DAYJOB.
I try to release all the lua libraries I can that aren't "secret sauce".

The lack of documentation for released libraries suggests this isn't a
common path of reasoning.

Sort of; see below.

Not at all IMO.
See the various tools that are installed via luarocks; ones I use
daily: busted, luacheck.


I think there is another category: people write single use scripts and utilities
e.g. converting files, data processing, personal automation.

For these applications, you often need to build a library to operate
with the device or create a binding to a library, which deserves to be
but the application is dead code the minute it is written.
