// Package assets gets us off go-bindata by using Go 1.16 embed support.
|
|
//
|
|
// For Go 1.16 embed, this source file had to live inside the assets/ folder
|
|
// to embed the sub-files, so couldn't be under pkg/ like pkg/bindata/ was.
|
|
//
|
|
// Historically code referred to assets like "assets/fonts/DejaVuSans.ttf"
|
|
// but Go embed would just use "fonts/DejaVuSans.ttf" as that's what's relative
|
|
// to this source file.
|
|
//
|
|
// The functions in this module provide backwards compatibility by ignoring
|
|
// the "assets/" prefix sent by calling code.
