     1  # vugufmt
     2  
     3  gofmt, but for vugu and html files.
     4  
     5  ## Goals
     6  
     7  * Match args and output as closely as possible to the original gofmt's general usecase.
     8  * Wrap around the actual gofmt; don't copy its code here.
     9  * Format HTML5 in addition to go source.
    10  * Report correct absolute line numbers and file names in the output.
    11  * Pure go implementation.
    12  
    13  ## Non-Goals
    14  
    15  * Support versions of HTML other than HTML5.
    16  
    17  ## Stretch-Goals
    18  
    19  * Pretty fmt'ing CSS. A lot of CSS these days is generated by a preprocessor like SASS or LESS.

    21  ## Implementation
    22  
    23  1. Use `golang.org/x/net/html` to parse the vugu file. This will probably need a tweak to handle the lack of a single root element, missing body, etc. This package has a Render function which re-prints the HTML parse tree, which we will use as the formatted output.
    24  2. Pass in text data for `<script type="application/x-go">` tags into gofmt. Capture its output.

    26  ## Sources
    27  
    28  This project took a lot of its code from [gofmt](https://golang.org/src/cmd/gofmt/gofmt.go) and Go's Token file. As such, I'm using the same license as gofmt.
