Hey all, how do you put an executable in your path through gems… like
when installing rails. you have a new command called “rails” what are
they doing to do that? - Thanks

When constructing your gem spec you need to include the bindir and the
executables array. For example, here is the relevant code from the
Rakefile for ActiveWarehouse ETL:

spec = Gem::Specification.new do |s|
#snip
s.bindir = “bin” # Use these for applications.
s.executables = [‘etl’]
s.default_executable = “etl”

snip

end

This would cause the script bin/etl to appear as an executable script
on the system where the gem is installed. Inside my bin/etl script I
usually delegate to code that’s actually in lib, however you may
implement as you see fit. HTH.
