GemExefy is RubyGems plugin aimed to replace batch files (.bat) with executables with the same name. This gem will work only on RubyInstaller Ruby installation and it requires RubyInstaller DevKit.
Reason for such replaceming batch files with executable stubs is twofold. When execution of batch file is interrupted with Ctrl-C key combination, user is faced with the confusing question
“Terminate batch job (Y/N)?”
which is avoided after replacement.
Second reason is appearance of processes in Task manager (or Process Explorer). In the case of batch files all processes are visible as ruby.exe. In order to distinguish between them, program arguments must be examined. In addition, having one process name makes it hard to define firewall rules. Having executable versions instead of batch files will facilitate process identification in task list as well as defining firewall rules. Moreover it makes it possible to create selective firewall rules for different Ruby gems. Installing Ruby applications as Windows services should be also much easer when executable stub is used instead of batch file.
How does it work?
If GemExefy is installed prior to other gems installation it will automatically install executable stub instead of each batch file that is normally created during gem installation. GemExefy enables replacement for existing gems too. Either all or one by one gem can be processed. Finally GemExefy can revert all changes and return all batch files instead of executable stubs if needed.
No known problems at the moment
Exefying single gem:
C:\> gem exefy <gem_name>
Exefying all installed gems on the system:
C:\> gem exefy --all
Reverting batch file for single gem:
C:\> gem exefy <gem_name> --revert
Reverting batch files for all previously processed gems:
C:\> gem exefy --all --revert
RubyInstaller Ruby version
gem install gem-exefy
After checking out the source, run:
$ rake newb
This task will install any missing dependencies, run the tests/specs, and generate the RDoc.
GemExefy searches following directories for batch files
Since Gem::path array contains directories pointing to the top level directory and executables are saved in the Gem#bindir folder, GemExefy concatenates directory from Gem.path with value of Gem#bindir (bin directory defined in the target Gem) and name from Gem#executables array with .bat extension. If such file is found it is replaced with corresponding executable file with same name and .exe extension.
