Sprockets::SourceMapUtils#format_source_map

Puglic: Transpose source maps into a standard format

NOTE: Does not support index maps

version => 3
file    => logical path
sources => relative from filename

  Unnecessary attributes are removed

Example

    map
    #=> {
    #  "version"        => 3,
    #  "file"           => "stdin",
    #  "sourceRoot"     => "",
    #  "sourceContents" => "blah blah blah",
    #  "sources"        => [/root/logical/path.js],
    #  "names"          => [..],
    #}
    format_source_map(map, input)
    #=> {
    #  "version"        => 3,
    #  "file"           => "logical/path.js",
    #  "sources"        => ["path.js"],
    #  "names"          => [..],
    #}
