go-templates

I have a go template like this: "environment": [ {{- range $k,$v := .env }} { "name": "{{ $k }}", "value": "{{ $v }}" }, {{- end }} ] and i am getting the output below: "environment": [ { "name": "name", "value": "test" }, { "name": "region", "value": "us-east-1" }, ] and i want to render it like below: "environment": [ { "name": "name", "value": "bxbd" }, { "name": "region", "value": "us-east-1" } ] I am not able to get rid of the last comma to make valid json. Or is it possible to somehow send the complete range block to some custom join function? Here's an example how to do it with

I use the following code which work ok, but now I want to print the template to a file and tried the following but got error package main import ( "html/template" "log" "os" ) func main() { t := template.Must(template.New("").Parse(`{{- range .}}{{.}}: echo "from {{.}}" {{end}} `)) t.Execute(os.Stdout, []string{"app1", "app2", "app3"}) f, err := os.Create("./myfile") if err != nil { log.Println("create file: ", err) return } err = t.Execute(f, t) if err != nil { log.Print("execute: ", err) return } f.Close() } The error is: execute: template: :1:10: executing "" at <.>: range can't iterate

This Go code always quotes a string: http://play.golang.org/p/8k4s8dv2PE in the template - you can see results. How can I generate var currentUser = null ? Note it also removes all comments from the code! How is it tuned up? This question is continuation of my Go: quoted string in templates . The html/template package is expressly designed to escape values. In your case, you're trying to pass JavaScript code in, rather than a simple value. You can accomplish this by changing the type of UserEmail to that of template.JS . This type wraps a string and expresses the intent that this value is

Template.ParseGlob("*.html") //fetches all html files from current directory. Template.ParseGlob("**/*.html") //Seems to only fetch at one level depth Im not looking for a "Walk" solution. Just want to know if this is possible. I don't quite understand what "pattern" this expects. if i can get an explanation about the pattern used by ParseGlob that would be great too. The code text/template/helper.go mentions // The pattern is processed by filepath.Glob and must match at least one file. filepath.Glob() says that "the syntax of patterns is the same as in Match " Match returns true if name

In my template, I would like to include some default meta tags (90% of the time). However, when a specific property is set, I would like to show a different set of text. I know I can set an anonymous struct and set a property with either "default" or "some-x" . However, this means, I need to add an anonymous struct to 90% of my handlers that just currently pass nil . Is there way to do something like {{if eq . nil}} // default meta tag {{else if eq .MetaValue "some-x"}} //other {{end}} If I try something like my above code, it compiles but doesn't do what I want. Appreciate any suggestions on
