中文文档

gowatch is a command line tool that builds and (re)starts your go project everytime you save a Go or template file.

Installation

To install gowatch use the go insall command:

go install github.com/silenceper/gowatch@latest

Then you can add gowatch binary to PATH environment variable in your ~/.bashrc or ~/.bash_profile file:

If you already have gowatch installed, updating gowatch is simple:

go get -u github.com/silenceper/gowatch

Usage

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.

Support Options

• -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)

Configuration file

In most cases, you don't need to specify the configuration. You can meet most of the requirements by directly executing the gowatch command.

You can initialize the gowatch.yml configuration file to the current directory with the default settings running the following command.

gowatch init

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.
