CompileDaemon watches your .go files in a directory and invokes go build if a file changed. Nothing more.
Installation
go get github.com/githubnemo/CompileDaemonExamples
In its simplest form, the defaults will do. With the current working directory set to the source directory you can simply…
CompileDaemon… and it will recompile your code whenever you save a source file.
If you want it to also run your program each time it builds you might add…
CompileDaemon -command="./MyProgram -my-options"… and it will also keep a copy of your program running. Killing the old one and starting a new one each time you build.
