Hi there, I'm implementing a protoc plugin for PHP and Javascript. The design of the protoc plugin system is great once you understand it :)
By reading the source code of protoc I've noticed that it's already possible to pass options to the plugins by appending them to the --lang_out argument. Anything before the path separator ":" will be included as a string in the "parameter" field of CodeGeneratorRequest. Like in the following example: protoc --php_out="option=value:./destination_path" tutorial.proto The problem with this syntax is that it's a bit limited (not possible to include colons ":" in the arguments) and then it's quite difficult for a human to use it. I've worked around this by creating a wrapper shell script for protoc that converts --lang-optname options to an url encoded string for use with the --lang_out option. However I feel that it'll be a great addition if protoc could do this natively, running the plugin command with any extra options given. Example: protoc --php_out=./destination_path --php-verbose --php-optimize=size --php-header=./header.txt That execution would make protoc run the protoc-gen-php plugin the following way: protoc-gen-php --verbose --optimize=size --header=./header.txt Note that since plugins options are prefixed by the plugin name, it's compatible with having several plugins defined. regards, /imv -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
