Strange: I'm not sure we've run on that node.js version, but the failure is surprising. We'll see if we can reproduce it.

As regards oXygen, I don't think they have yet released a version with support for Saxon-JS 2. You'll have to wait for that.

I upgraded to node.js 14.9.0 (on MacOS) and couldn't reproduce the problem:

mackay:samples mike$ xslt3 -xsl:styles/books.xsl -t -nogo -export:/dev/null
Saxon-JS 2.0 from Saxonica 
Node.js version v14.9.0
Compiling stylesheet /Users/mike/repo/samples/styles/books.xsl
Stylesheet compilation time: 0.456s
Stylesheet exported to SEF file /dev/null
mackay:samples mike$

I'll give it a try on a Windows box in the morning.

I've now installed node.js 14.9.0 and Saxon-JS 2 on Windows, and I'm getting a different error:

This is some kind of problem with Windows line endings which needs to be investigated separately, but it's got well beyond the point where you were reporting it failing. So it's hard to know what to suggest next. I guess if you upgraded from 14.8 to 14.9 that would eliminate one (unlikely) possible cause.

I have raised the Windows line ending problem as bug #4702 (though on investigation, it's debatable whether it's a bug).

I wasn't able to reproduce it either. Have you tried the nuclear option of deleting node_modules and reinstalling? I wonder if there's some cruft lying around from some other upgrade operation or something.

Looking more closely at the actual error messages, and the corresponding code paths, we see both

Command line option -xsl requires a value

and

Invalid command line input: test.xsl

This suggests to me that the input -xsl:test.xsl has somehow reached Saxon as two separate arguments, -xsl and test.xsl. So perhaps the command line input is somehow being mangled before it reaches Saxon?

Are you perhaps using PowerShell? In such cases PowerShell preparses the arguments/options, whereas xslt3 expects to do its own parsing, so quoting is needed. I thought I’d documented this somewhere but can’t find at present.

I am using PowerShell on Windows 10. Still getting the same error despite
quoting the stylesheet and source.

I think possibly John meant you had to quote the whole argument so that PowerShell doesn't try to: "-xsl:newFeatures.xsl" but I could be mistaken.

Updated by John Lumley over 3 years ago

IIRC you have to quote the complete pair e.g. “-xsl:foo.xsl”

As a check alternative use cmdprompt to check - it’s what I use for all my compilations... I don’t need PowerShell capabilities

Hmm ... using the command prompt did the trick. So it looks to be a
Powershell issue

Tracker changed from Bug to Support
Subject changed from Having severe Saxon-JS errors to Problems running Saxon-JS CLI from Powershell
Status changed from New to In Progress
Assignee set to Debbie Lockett
Priority changed from High to Normal

Reclassifying and relabelling this as a support issue. But leaving open, because we should add some details in the documentation.

Note also the previous saxon-help list discussion (from June 2020):

Willem Van Lishout:

Not sure if a bug or not, but running Saxon-JS 2 from Powershell 7.0 on Windows only seems to work when the arguments (including their keys) are wrapped inside double quotes.

So this doesn't work: xslt3 -s:c:\temp\temp.xml -xsl:c:\temp\Untitled1.xsl

(Missing '=' in parameter 'c:\temp\temp.xml' Internal error: bad input to string constructor #undefined)

While this does work (and it took me quite a while to figure it out): xslt3 "-s:c:\temp\temp.xml" "-xsl:c:\temp\Untitled1.xsl"

This only happens in Powershell, not in cmd.exe.

John Lumley:

Apparently when Powershell sees ‘-something’ it parses an argument of the given name which is passed to the command... see https://stackoverflow.com/questions/5527261/how-to-pass-arugments-to-saxon-xquery-in-windows-powershell for some old stuff on this. xslt3 does its own argument processing, based on the white space-separated array args Node.js process uses.
