See for yourself at the [W3C Validator](http://validator.w3.org/)!* + +Minify is a minifier package written in [Go][1]. It provides HTML5, CSS3, JS, JSON, SVG and XML minifiers and an interface to implement any other minifier. Minification is the process of removing bytes from a file (such as whitespace) without changing its output and therefore shrinking its size and speeding up transmission over the internet and possibly parsing. The implemented minifiers are designed for high performance. + +The core functionality associates mimetypes with minification functions, allowing embedded resources (like CSS or JS within HTML files) to be minified as well. Users can add new implementations that are triggered based on a mimetype (or pattern), or redirect to an external command (like ClosureCompiler, UglifyCSS, ...). + +### Sponsors + +[![SiteGround](https://www.siteground.com/img/downloads/siteground-logo-black-transparent-vector.svg)](https://www.siteground.com/) + +Please see https://www.patreon.com/tdewolff for ways to contribute, otherwise please contact me directly! + +#### Table of Contents + +- [Minify](#minify) + - [Prologue](#prologue) + - [Installation](#installation) + - [API stability](#api-stability) + - [Testing](#testing) + - [Performance](#performance) + - [HTML](#html) + - [Whitespace removal](#whitespace-removal) + - [CSS](#css) + - [JS](#js) + - [Comparison with other tools](#comparison-with-other-tools) + - [Compression ratio (lower is better)](#compression-ratio-lower-is-better) + - [Time (lower is better)](#time-lower-is-better) + - [JSON](#json) + - [SVG](#svg) + - [XML](#xml) + - [Usage](#usage) + - [New](#new) + - [From reader](#from-reader) + - [From bytes](#from-bytes) + - [From string](#from-string) + - [To reader](#to-reader) + - [To writer](#to-writer) + - [Middleware](#middleware) + - [Custom minifier](#custom-minifier) + - [Mediatypes](#mediatypes) + - [Examples](#examples) + - [Common minifiers](#common-minifiers) + - [External minifiers](#external-minifiers) + - [Closure Compiler](#closure-compiler) + - [UglifyJS](#uglifyjs) + - [esbuild](#esbuild) + - [Custom minifier](#custom-minifier-example) + - [ResponseWriter](#responsewriter) + - [Templates](#templates) + - [FAQ](#faq) + - [License](#license) + +### Roadmap + +- [ ] Use ASM/SSE to further speed-up core parts of the parsers/minifiers +- [x] Improve JS minifiers by shortening variables and proper semicolon omission +- [ ] Speed-up SVG minifier, it is very slow +- [x] Proper parser error reporting and line number + column information +- [ ] Generation of source maps (uncertain, might slow down parsers too much if it cannot run separately nicely) +- [ ] Create a cmd to pack webfiles (much like webpack), ie. merging CSS and JS files, inlining small external files, minification and gzipping. This would work on HTML files. + +## Prologue +Minifiers or bindings to minifiers exist in almost all programming languages. Some implementations are merely using several regular expressions to trim whitespace and comments (even though regex for parsing HTML/XML is ill-advised, for a good read see [Regular Expressions: Now You Have Two Problems](http://blog.codinghorror.com/regular-expressions-now-you-have-two-problems/)). Some implementations are much more profound, such as the [YUI Compressor](http://yui.github.io/yuicompressor/) and [Google Closure Compiler](https://github.com/google/closure-compiler) for JS. As most existing implementations either use JavaScript, use regexes, and don't focus on performance, they are pretty slow. + +This minifier proves to be that fast and extensive minifier that can handle HTML and any other filetype it may contain (CSS, JS, ...). It is usually orders of magnitude faster than existing minifiers. + +## Installation +Make sure you have [Git](https://git-scm.com/) and [Go](https://golang.org/dl/) (1.13 or higher) installed, run +``` +mkdir Project +cd Project +go mod init +go get -u github.com/tdewolff/minify/v2 +``` + +Then add the following imports to be able to use the various minifiers +``` go +import ( + "github.com/tdewolff/minify/v2" + "github.com/tdewolff/minify/v2/css" + "github.com/tdewolff/minify/v2/html" + "github.com/tdewolff/minify/v2/js" + "github.com/tdewolff/minify/v2/json" + "github.com/tdewolff/minify/v2/svg" + "github.com/tdewolff/minify/v2/xml" +) +``` + +You can optionally run `go mod tidy` to clean up the `go.mod` and `go.sum` files. + +See [CLI tool](https://github.com/tdewolff/minify/tree/master/cmd/minify) for installation instructions of the binary. + +### Docker + +If you want to use Docker, please see https://hub.docker.com/r/tdewolff/minify. + +```bash +$ docker run -it tdewolff/minify --help +``` + +## API stability +There is no guarantee for absolute stability, but I take issues and bugs seriously and don't take API changes lightly. The library will be maintained in a compatible way unless vital bugs prevent me from doing so. There has been one API change after v1 which added options support and I took the opportunity to push through some more API clean up as well. There are no plans whatsoever for future API changes. + +## Testing +For all subpackages and the imported `parse` package, test coverage of 100% is pursued. Besides full coverage, the minifiers are [fuzz tested](https://github.com/tdewolff/fuzz) using [github.com/dvyukov/go-fuzz](http://www.github.com/dvyukov/go-fuzz), see [the wiki](https://github.com/tdewolff/minify/wiki) for the most important bugs found by fuzz testing. These tests ensure that everything works as intended and that the code does not crash (whatever the input). If you still encounter a bug, please file a [bug report](https://github.com/tdewolff/minify/issues)! + +## Performance +The benchmarks directory contains a number of standardized samples used to compare performance between changes.

In many cases, using a literal newline doesn't affect the file size, and in some cases it may even reduce the file size. + +A typical example is HTML. Whitespace is significant in HTML, meaning that spaces and newlines between or around tags may affect how they are displayed. There is no distinction between a space or a newline and they may be interchanged without affecting the displayed HTML. Remember that a space (0x20) and a newline (0x0A) are both one byte long, so that there is no difference in file size when interchanging them. This minifier removes unnecessary whitespace by replacing stretches of spaces and newlines by a single whitespace character. Specifically, if the stretch of white space characters contains a newline, it will replace it by a newline and otherwise by a space. This doesn't affect the file size, but may help somewhat for debugging or file transmission objectives. + +Another example is JavaScript. Single or double quoted string literals may not contain newline characters but instead need to escape them as `\n`. These are two bytes instead of a single newline byte. Using template literals it is allowed to have literal newline characters and we can use that fact to shave-off one byte! The result is that the minified output contains newlines instead of escaped newline characters, which makes the final file size smaller. Of course, changing from single or double quotes to template literals depends on other factors as well, and this minifier makes a calculation whether the template literal results in a shorter file size or not before converting a string literal. + +## License +Released under the [MIT license](LICENSE.md). + +[1]: http://golang.org/ "Go Language" diff --git a/vendor/github.com/tdewolff/minify/v2/common.go b/vendor/github.com/tdewolff/minify/v2/common.go new file mode 100644 index 0000000..3773a9b --- /dev/null +++ b/vendor/github.com/tdewolff/minify/v2/common.go @@ -0,0 +1,524 @@ +package minify + +import ( + "bytes" + "encoding/base64" + + "github.com/tdewolff/parse/v2" + "github.com/tdewolff/parse/v2/strconv" +) + +var ( + textMimeBytes = []byte("text/plain") + charsetASCIIBytes = []byte("charset=us-ascii") + dataBytes = []byte("data:") + base64Bytes = []byte(";base64") +) + +// Epsilon is the closest number to zero that is not considered to be zero. +var Epsilon = 0.00001 + +// Mediatype minifies a given mediatype by removing all whitespace and lowercasing all parts except strings (which may be case sensitive). +func Mediatype(b []byte) []byte { + j := 0 + inString := false + start, lastString := 0, 0 + for i, c := range b { + if !inString && parse.IsWhitespace(c) { + if start != 0 { + j += copy(b[j:], b[start:i]) + } else { + j += i + } + start = i + 1 + } else if c == '"' { + inString = !inString + if inString { + if i-lastString < 1024 { // ToLower may otherwise slow down minification greatly + parse.ToLower(b[lastString:i]) + } + } else { + lastString = j + (i + 1 - start) + } + } + } + if start != 0 { + j += copy(b[j:], b[start:]) + parse.ToLower(b[lastString:j]) + return b[:j] + } + parse.ToLower(b[lastString:]) + return b +} + +// DataURI minifies a data URI and calls a minifier by the specified mediatype.
