I always forgot how to compile proto file and here is how compile .proto file for my personal note. 😀
$ protoc -I proto_dir/ proto_dir/proto_file.proto --go_out=plugins=grpc:proto
Example above for golang implementation, another programming language can use another out parameter.
--cpp_out=OUT_DIR Generate C++ header and source.
--csharp_out=OUT_DIR Generate C# source file.
--java_out=OUT_DIR Generate Java source file.
--objc_out=OUT_DIR Generate Objective C header and source.
--php_out=OUT_DIR Generate PHP source file.
--python_out=OUT_DIR Generate Python source file.
$ curl -s http://php-osx.liip.ch/install.sh | bash -s 7.1
$ export PATH=/usr/local/php5/bin:$PATH

I just installing vim on my machine, but it affected to my installed git. Every I merge my working branch, I always got this error.
error: There was a problem with the editor 'vi'.
Not committing merge; use 'git commit' to complete the merge.
After that, I have to commit manually to the merged changes.
$ git commit "merge from ... to ..."
The error because git using “vi” as the editor and I installed “vim” in my machine.
Here is how to fix this.
$ which vim
$ git config --global core.editor /usr/local/bin/vim

$ grep -nr 'keyword' target/directory --include=*.html

I’m writing simple script to save both on remote and also local disk. To use this class, you just need to subclass this mixin class. Keep in mind to pay attention with mixin class order.
Currently only support save to local disk, but not supported yet to remove local file if the instance removed. Don’t hesitate to fork or improve my code. 😀
