v2.6.1

Upgrade to tdewolff/parse@2.3.14:

• Re-parse input immediately when encountering parse error. Previously this was only done if the error was actually read which would save us from re-parsing the file (i.e. better performance). However, an error is (a) rare and (b) happens only once per file. Re-parsing on errors does not impact the performance of well formatted files, and a reliable error message is valued more.
• Bugfix: prevent infinite loop on error on input file that contains unicode code points (i.e. any character bigger than 0xC0 usually followed by more bytes).
• Improve error messages for parsers to include parser name and print offending byte(s)

v2.6.0

• CSS: remove space after function in property value; margin:calc(10px) calc(20px) => margin:calc(10px)calc(20px)
• SVG: parse A path command correctly when the booleans largeArc and sweep are not separated by a space, such as in A10 10 0 0120 0 which is equivalent to A10 10 0 0 1 20 0
• SVG bugfix: make sure we are processing a valid path command
• SVG bugfix: prevent panic when having insufficient path arguments
• cmd: surpress error when minifying empty directory
• HTML: only minify attributes for known HTML5 tags, fixes #270
• HTML, XML, SVG: minify entities with parse@2.3.13 such as: " => ", " => ", " => ", ’ => ’, ✏ => ✏.

v2.5.2

Bugfixes:

• SVG: don't convert polyline/rect/polygon/line to path, which can break CSS, fixes #260
• SVG: relative SVG Bézier commands not properly minified
• CSS: don't remove whitespace in nested unknown at-rules, fixes #262
• CSS: fix panic for background when it contains functions other than calc for background-position, fixes #263

• Make M concurrent-safe
• HTML: keep double quotes around XML-flavour RDFa attributes
• CSS: revert the use of the #RRGGBBAA format as proposed in Color Module Level 4 as it is not yet an official W3C recommendation
• CSS: background-position (also within background) now works with 3 and 4 values as well
• SVG: skipping metadata or rect tags properly even if they are closed by a void tag (like <rect/>)
• 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/v2@v2.3.7: 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).

• CSS: improve minification for font, background, background-position, background-repeat, background-size, outline and border declarations

• 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: do not collapse outline to 0 but to none
• CSS bugfix: opacity for rgba() and hsla() in CSS2 cannot be rewritten as #rrggbbaa
