goemon

Go Extensible Monitoring

Speed up your development. If you updated js files, the page should be reloaded. If you updated go files, the app should be recompiled, and should be restarted. And also, the page should be reloaded

Expected directory structure

+---assets
|   +- index.html
|   +- app.css
|   +- app.js
+- main.go

Usage

For example:

Run web server

$ goemon -g > goemon.yml
$ goemon go run main.go

Writing markdown

$ goemon -g md > goemon.yml
$ goemon --

Writing C code

$ goemon -g c > goemon.yml
$ goemon --

Default configuration

# Generated by goemon -g
livereload: :35730
tasks:
- match: './assets/*.js'
  commands:
  - minifyjs -m -i ${GOEMON_TARGET_FILE} > ${GOEMON_TARGET_DIR}/${GOEMON_TARGET_NAME}.min.js
  - :livereload /
- match: './assets/*.css'
  commands:
  - :livereload /
- match: './assets/*.html'
  commands:
  - :livereload /
- match: '*.go'
  commands:
  - go build
  - :restart
  - :livereload /

match is wildcard. You can use ./foo/bar/**/*.js like a shell.
commands is list of commands to run. :XXX is internal command.

Internal Command	Behavior
:livereload /path	reload `path`
:minify	minify js/css(work in progress)
:restart	restart app
:sleep 3000	sleep 3000ms
:fizzbuzz 100	do fizzbuzz(1 to 100)
:event :Foo	fire event :Foo

:event :Foo fire event defined - match: :Foo.

Currently, :minify is work in progress. So you should run minifyjs command to do it. For example, configuration in above works as below.

Pattern	Behavior
./assets/*.css	reload page
./assets/*.js	minify js/css, reload page
./assets/*.html	reload page
./assets/*.go	build, restart app, reload page

LiveReload

You can use livereload feature.

Use goemon as library

cat > goemon.go
package main

import (
    _ "github.com/mattn/goemon/auto"
)
^D

Then go build. You don't need to use goemon command.

Installation

$ go get github.com/mattn/goemon/cmd/goemon

If you want to minify js, install minifyjs like below.

$ npm install -g minifyjs
