gowatch

Golang program real-time compilation tools to enhance development efficiency

Real-time compilation by monitoring file changes in a specified directory

install

go get github.com/jackywu/gowatch

After the installation is complete, you can use the gowatch command to execute in the main package:

Command line parameters

-o : Optional，specify the target build path
-p : Optional，Specified the need to build the package, which can also be a single file
-g : Optional, specify the time gap during which gowatch will ignore any file modification event
-x : Optional, specify the file's modification event will be ignored which match the regex-pattern

example:

simple example: gowatch -o cmd/apiserver.go -p cmd/apiserver

with args: gowatch -o cmd/apiserver.go -p cmd/apiserver -args "start --binding-address=0.0.0.0"

exclude *_test.go file: gowatch -o cmd/apiserver.go -p cmd/apiserver -x ".*_test.go" -args "start --binding-address=0.0.0.0 --binding-port=1234"

with time gap(in 60 seconds, any file modification event will be ignored): gowatch -o cmd/apiserver.go -g 60 -p cmd/apiserver -x ".*_test.go" -args "start --binding-address=0.0.0.0"

config file

gowatch.yml

Most of the time, you do not need to change the configuration to do most of what you need to do with the gowatch command, but it also provides some configuration for customizing. Create the gowatch.yml file in the executable:

# gowatch.yml Configuration example

# The name of the generated executable file, the default is the current directory name
appname: "test"
# specify the compiled target file directory
output: /bin/demo
# Need to monitor the additional file name suffix, the default only '.go' file
watch_exts:
    - .yml
# need to monitor the directory, the default only the current directory
watch_paths:
    - ../pk
# when the program is executed, additional parameters need to be added
cmd_args:
    - arg1=val1
# need to increase the additional environment variables, the default has been loaded by the current environment variables
envs:
    - a=b
# whether to monitor the 'vendor' folder under the file changes
vendor_watch: false
# do not need to listen to the directory
excluded_paths:
    - path
# do not watch these file which match the regex-pattern
ExcludedPattern: ""
# main package path, can also be a single file, multiple files separated by commas
build_pkg: ""
# build tags
build_tags: ""

# any file modification event will be ignored during this time gap, unit: second
BuildGap: 0
