Supports live reloading for Go
- Better features than github.com/pilu/fresh
- Supports cross compile and live reloading on host OS for
dockerusers (Very Fast forDocker for Macuser ) - Supports cross compile by cgo ( C/C++ ) ( currently, works on macOS ( and target architecture is
amd64) only ) - Supports helper commands for
go rungo testgo build
rebirth needs configuration file (rebirth.yml ) to running .rebirth init create it .
rebirth.yml example is the following.
task:migrate:desc:migrate schemacommands: -mysql ....host:docker:container_namebuild:main:path/to/main.go# change path to main package ( default: . )init: -echo 'init hook'# called once at startingbefore: -echo 'before hook'# called before buildafter: -echo 'after hook'# called after buildenv:CGO_LDFLAGS:/usr/local/lib/libz.arun:env:RUNTIME_ENV:"fuga"watch:root: .# root directory for watching ( default: . )ignore: -vendor
task: define custom commandhost: specify host information for running to an application ( currently, supportsdockeronly )build: specify ENV variables for buildingrun: specify ENV variables for runningwatch: specifyrootdirectory orignoredirectories for watching go file
