CSS Validation

332 words on

When writing CSS it’s a good idea to validate your style sheets. The W3C offer a validator for that. Which in principle can be downloaded to your local computer, but doing so requires using CVS and possibly more pain to actually get things set up afterwards. So I have never done that but just used their website form instead. Being lazy by nature I finally wrote a script that just opens the validator automatically for my frontmost SubEthaEdit document in the hope that it inspires more regular usage of the validator. For other editors it’s also available as a system Service.

So, for your convenience:

You will need UnicodeChecker for the script to work. The system Service was created courtesy of ThisService. Alternatively just look at it:

tell application "SubEthaEdit" to set theText to plain text of first document

on process(theText)
    — convert spaces to +
    set oldTID to AppleScript’s text item delimiters
    set AppleScript’s text item delimiters to {" "}
    set textArray to text items of theText
    set AppleScript’s text item delimiters to {"+"}
    set theText to textArray as string
    set AppleScript’s text item delimiters to oldTID
    — URL encoding
    tell application "UnicodeChecker" to set URLText to escape theText to URL preserving " +abcdefghijklmnopqrstuvwxyzABCDEFGHJIJKLMNOPQRSTUVWXYZ1234567890" without preserving default set
    — creating and opening the URL
    set myURL to "http://jigsaw.w3.org/css-validator/validator?text=" & URLText
    tell application "System Events"
        if (count (processes whose name is "Safari")) is not 0 then
            tell application "Safari"
                if URL of first document contains "jigsaw.w3.org/css-validator/" then
                    — re-use the previously used CSS validator display
                    set URL of first document to myURL
                end if
            end tell
        end if
        — otherwise just open the URL in the default browser
        open location myURL
    end tell
end process
