• SVG pathdata: when cursor doesn't move, don't emit any commands

Go modules support #2

I'm suspecting that go mod gets confused from a previously reverted v2.3.7 release, so just in case this is a new release that will hopefully fix:

$ go get -u github.com/tdewolff/minify/v2
go: github.com/tdewolff/minify/[email protected]: go.mod has non-.../v2 module path "github.com/tdewolff/minify" (and .../v2/go.mod does not exist) at revision v2.3.7
go get: error loading module requirements

Go modules support

Add Go modules support by using the github.com/tdewolff/minify/v2 import path.

WARNING: this release may give errors for go mod probably due to (local) caching...

Bugfixes and improved CSS minifier

Important: default mimetype for JavaScript is now application/javascript (it used to be text/javascript).

• HTML bugfix: keep empty value attribute on <input type="radio">, because the default is not an empty string
• HTML bugfix: prevent IE conditional comments from panicking in some instances
• CSS: handle local() for URLs

• CSS: improve minification for font, background, background-position, background-repeat, background-size, outline and border declarations
• CSS: reintroduce support for IE star-declaration hack
• CSS bugfix: margin and padding now check if values that are functions (such as calc()) are equal and thus eligible for collapsing
• CSS bugfix: parse bad declarations better
• CSS bugfix: add space for attribute selector case insensitivity between the value and i as in input[type="radio" i]
• CSS bugfix: do not collapse outline to 0 but to none
• CSS bugfix: opacity for rgba() and hsla() in CSS2 cannot be rewritten as #rrggbbaa

Bugfixes found by fuzz testing

This release fixes a number of out-of-bounds panics that could arise in HTML, XML and JS sources. It also allows HTML sources to contain the NULL byte.

Remove dependencies on buffer and strconv

v2.3.3

Change buffer to parse/buffer

v2.3.1

This release has binaries built by GoReleaser.
