Should be part of the context

p.Task("server", nil, func (c *Context) {
    fmt.Println(c.FileEvent.Path)
})

here is my code :

package main

import ( "fmt"

. "gopkg.in/godo.v1"

)

func Tasks(p *Project) { Env = "GOPATH=$GOPATH" p.Task("default", D{"build"}) p.Task("build", W{"src/ * */ *.go"}, func(c *Context) { fmt.Println(c.FileEvent.Path)

})

} func main() { Godo(Tasks) }

I figured it out

When godo is booting up, the event is triggered once and then c.FileEvent is nil.

When godo has booted, c.FileEvent will not be nil

so the following works for me:

p.Task("lint-php", nil, func(c *do.Context) {
    if c.FileEvent == nil {
        return
    }
    c.Run(fmt.Sprintf("php -l %s", c.FileEvent.Path))
}).Src("app/**/*.{php}")

To clarify, the initial task run is programmatic and subsequent runs are react to file watch events.
