[PATCH v2 16/44] ruby: bind git_config()
Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com>
---
Notes:
Our first usage of Ruby blocks.
Notice how the code inside the block is in the same scope as the code outside.
cb_data = "config"
git_config() do |key, value|
puts "%s: %s=%s" % [cb_data, key, value]
end
This invalidates the need for callback data, because the block has access to
those variables already. ruby.c | 15 +++++++++++++++
