Fmt Go HTML templates. There is one option. The indenting used is 1 tab - this allow your terminal's tab width setting to do its work. The formatter is rather simple, there is no AST creation, it just iterates over a list of tokens.
Before a {{block}} or {{define}} an extra newline is introduced.
Both HTML tag and template verbs are used for the indentation; in a complete template this does what you expect. For the HTML block tags: html, body, head, meta, main, nav we do not add a positive indent.
{{if .X}}
<body class="X">
{{else}}
<body>
{{end}}
instead of:
{{if .X}}
<body class="X">
{{else}}
<body>
{{end}}
where the second <body> would indent the template even further.
go build./gotmplfmt < template.go.tmpl
