gowatch is a command line tool that builds and (re)starts your go project everytime you save a Go or template file.
To install gowatch use the go get command:
go get github.com/silenceper/gowatchThen you can add gowatch binary to PATH environment variable in your ~/.bashrc or ~/.bash_profile file:
If you already have
gowatchinstalled, updatinggowatchis simple:
go get -u github.com/silenceper/gowatch
cd /path/to/myapp
Start gowatch:
gowatch
Gowatch will watch for file events, and every time you create/modify/delete a file it will build and restart the application,If go build returns an error, it will log it in stdout.
- -o : Not required, specify the target file path for the build
- -p : Not required, specify the package to be built (can also be a single file)
- -args: Not required, specify program runtime parameters, for example: -args = '-host =: 8080, -name = demo'
- -v: Not required, display gowatch version information
example:
gowatch -o ./bin/demo -p ./cmd/demo
In most cases, you don't need to specify the configuration. You can meet most of the requirements by directly executing the gowatch command.
Create a gowatch.yml file in the execution directory:
# gowatch.yml configuration example
# The name of the executable file generated under the current directory execution. The default is the current directory name.
appname: "test"
# Specify the command to run after builds done
run_cmd: "./run.sh"
# Specify the directory where the compiled object files are stored
output: /bin/demo
# The file name suffix that needs to be monitored. By default, there is only a '.go' file.
watch_exts:
- .yml
# The directory that needs to listen for file changes. By default, only the current directory.
watch_paths:
- ../pk
# Additional parameters that need to be added when running the application
cmd_args:
- arg1=val1
# Additional parameters that need to be added when building the application
build_args:
- -race
# Need to increase environment variables, the current environment variables are loaded by default
envs:

# Whether to listen to file changes in the 'vendor' folder
vendor_watch: false
# Directory that do not need to listen for file changes
excluded_paths:
- path
# main package path, can also be a single file, multiple files separated by commas
