gosu is a build tool for Go in the spirit of Rake, Gulp, Projmate ... gosu supports watching, globbing, tasks and importing other projects.
Asset.pipeline is in the works. Much simpler than Gulp or Grunt.
go get github.com/mgutz/gosu
gosu does not have its own executable. Instead, use gosu to build your project build tool.
import (
gosu"github.com/mgutz/gosu"
)
func Project(p *gosu.Project) {
p.Task("default", "Runs all tasks" string[]{"stylesheets", "app"})
p.Task("stylesheets", gosu.Files{"public/css/**/*.less"}, func(c *gosu.Context) {
if c.FileEvent != nil {
// c.FileEvent contains change event from watch
}
for _, f := range c.Task.WatchFiles {
// f.FileInfo and f.Path
}
})
p.Task("app", "(Re)runs the app", gosu.Files{"**/*.go"}, func() {
// use any restart package here
})
}
func main() {
gosu.Run(Project)
}To run default task: go run main.go
To run a single task: go run main.go stylesheets
To run and watch a task: go run main.go --watch stylesheets
Build your utility:
go build -o gosu main.go # name it whatever you want
gosu --watch stylesheets # profit
All file patterns MUST start with a directory:
- OK
"./test.go" - Bad
"test.go"
Project.Task has variable arguments of type interface{} for usability.
Tasks MUST define Handler, ContextHandler or have Dependencies
To add a default task, which runs when a task on command-line is not provided
p.Task("default", string[]{"clean", "stylesheets", "views"})To add a task with description and Handler
p.Task("name", "description", func() {
// work here
})To add a task with description and ContextHandler
p.Task("name", "description", func(c *gosu.Context) {
// use context to get info about c.FileEvent or c.Task
})
To add a task with Dependencies
p.Task("name", string[]{"dep1", "dep2"})To support watching, add glob patterns
p.Task("views", gosu.Files{"./views/**/*.go.html"}, func() {
// compile templates
})
/**/ - match zero or more directories
{a,b} - match a or b, no spaces
* - match any non-separator char
? - match a single non-separator char
**/ - match any directory, start of pattern only
/** - match any this directory, end of pattern only
! - removes files from resultset, start of pattern only
import (
"github.com/acme/project"
)
func Project(p *Project) {
// Use it within this project and assign namespace "ns"
p.Use("ns", project.Project)
// Add as dependency, note the namespace
p.Task("default", []string{"ns:sprite"})
