class Spring::Client::Binstub
Constants
- BINSTUB_VARIATIONS
- LOADER
If loading the bin/spring file works, it'll run spring which will eventually call Kernel.exit. This means that in the client process we will never execute the lines after this block. But if the spring client is not invoked for whatever reason, then the Kernel.exit won't happen, and so we'll fall back to the lines after this block, which should cause the “unsprung” version of the command to run.
- OLD_BINSTUB
- SHEBANG
- SPRING
The defined? check ensures these lines don't execute when we load the binstub from the application process. Which means that in the application process we'll execute the lines which come after the LOADER block, which is what we want.
