Language Support Request: XSLT

[spodzone]

Please could we have a beautifier for files .xsl, .xslt ?

Ideally, typical XML 2-space indent and a blank line between xsl elements such as xsl:template, xsl:output, etc.

Thanks!

If you change your file's grammar to XML does it work well for beautification? Let me know, because if treating this as XML works then this will be a very quick fix to get XSLT support since we can already handle XML.

To change your grammar go to Atom's menu -> Edit -> Select Grammar.

Thanks; switching the grammar allows beautify to run, and the results remain unchanged by subsequent re-beautifications, but it doesn't really add much.

0) correct: it generally introduces a regular 4-space indent, that's fine.

1) major bug: it has broken a mention of <xsl:text> by introducing spaces: <xsl : text>.

2) bug: it introduces a double space between elements and their attributes <link [double-space here] href="/skin/style-display.css" rel="STYLESHEET" type="text/css"/>

3) bug: comment PIs are not indented

4) nice to have: wrap+indent attributes to keep the line-length sane - currently these come out all on one line(!):

<xsl:transform 
    exclude-result-prefixes="xsd xsl" 
    version="1.1" 
    xmlns:h="http://www.w3.org/1999/xhtml" 
    xmlns:q="http://www.w3.org/2005/sparql-results#" 
    xmlns:xhtml="http://www.w3.org/1999/xhtml" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

5) nice to have: blank lines before <xsl:template> declarations, before <xsl:stylesheet>, before <xsl:output>, and indent <xsl:param> and <xsl:variable> 4 spaces.

I'm new to Atom, but from previous lives, I used to pipe a buffer through this little shell script - included here to assist what I'd like to emulate:

#!/bin/sh

export PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin

basic() {
  xmlstarlet fo -s 2
}

nltemplate() {
    sed -E 's#<xsl:template#\n  <xsl:template#g'
}

stylesheet() {
    sed -E '/<xsl:stylesheet/s# #\n    #g'
}

stylespace() {
    sed -E 's#<xsl:stylesheet#\n<xsl:stylesheet#'
}

paramspace() {
    sed -E '1,/<xsl:param/s#<xsl:(param)#\n  <xsl:\1#'
}

outputspace() {
    sed -E '1,/<xsl:output/s#<xsl:(output)#\n  <xsl:\1#'
}

variablespace() {
    sed -E '1,/<xsl:variable/s#<xsl:(variable)#\n  <xsl:\1#'
}

nowhitespaceblanklines() {
    sed -E 's#^[ \t]*$##'
}

basic | nltemplate | stylesheet | stylespace | paramspace | outputspace | variablespace | nowhitespaceblanklines

Also a couple of images just for amusement - what I'd like and what it gives.

Cheers

Interesting. Please run the Atom command from the command palette: Atom Beautify: Help Debug Editor. This will provide me with some more debugging information. Please put this into a Gist with the extension .md (it is a markdown file) and post the link here. Thanks!

The real breakage with the xsl : text happens just after a bunch of inline JS script at the bottom near the </body> tag.

HTH!

@spodzone I provide the XML support for Atom-Beautify. Would you mind opening a bug at https://github.com/prettydiff/prettydiff/issues and list as bullet points features you would like to extend XML beautification into a more desirable format for XSLT?
