Notas del editor
- How many of you have full control over your application deployment? How many of your know how many instance of your application there will be? Desktop applications? IT Shops? distribute small apps to your company for command / control monitoring ?
- Anyone, in the audience have any ideas?
- eee is an exractor written in pascal eee.gz is ruby + extensions + the application trailer at the end. mac, windows, linux, cygwin
- Shooes is pretty cool, and targeted towards gui based applications.
- I do not want to worry about cleaning up temporary files. I want to deployt to Solaris, AIX, HPUX, virtually anywhere ruby can run, I want crate to run.
- I do not want to worry about cleaning up temporary files. I want to deployt to Solaris, AIX, HPUX, virtually anywhere ruby can run, I want crate to run.
- Create a table to store all the ruby code from the standard library and gems
- Very similar to how rubygems works.
- 1. initialize the ruby interpreter 2. set ARGV for ruby 3. initialize all statically compiled extensions 4. bootstrap the Amalgalite driver 5. remove all filesystem directories from the $LOAD_PATH 6. switch to using Amalgalite backed require 7. require the file in the C constant CRATE_MAIN_FILE 8. instantiate a single instance of the class named in the C constant CRATE_MAIN_CLASS 9. invoke run( ARGV, ENV) on the newly instantiated class 10. exit
- I left out a fair bit of nitty gritty details would you like me to expand on anything, show some more code, yell and scream at me,
