The Saxon website says Saxon/C can be invoked from Perl, but I can't find any examples. The only thing I've found that interfaces to Saxon is one old Perl module (XML::Saxon::XSLT2) which uses Inline::Java and apparently is very slow. But I can find nothing that uses Saxon/C. Has anyone had any success in doing this who can share some tips?
we have not yet officially done the integration work needed to extend Saxon/C on perl it is still on our todo list. Therefore we currently don't support it. I don't know of anyone who has done this work as yet but I know it is can be done.
On the Saxon website we state that it is possible to create extensions in languages like Perl since Saxon/C has a C/C++ interface. Currently, we only have extensions for PHP and Python (available in the next release).
As a workaround you could run the transform command from Saxon/C using the exec function in Perl instead of the Java version, therefore avoiding the need to run Java VM.

We have set of unix shell(ksh) scripts used for deployment of our product.
Actually there is a mixture of ksh+sed+awk+ant code.
Our product works on AIX only so we did not try to do our scripts portable.
But now we need to run part of our scripts not only on AIX but on Windows also.
We need to have ability to create/update DB both from AIX and from Windows.
Now for this part of functionality we use ksh+ant.
We have a requirement to install as few as possible tools on this Windows box.
In the best case it should be JRE+our products only.
What do you propose to use instead of ksh?
As I know we can put Groovy jar into our project and write this part of functionality on Groovy.
In this case this code will be portable.
May be there are better solutions than Groovy?
Any JVM language such as Jython or Scala should work as well as Groovy so it’s really a choice of what the developers are comfortable with. I’ve had good success with Groovy and have been able to bundle Groovy as a jar file and execute any script I wanted in the following way
Java -jar groovy.jar myscript.groovy
I’ve been able to do this on z/OS, Windows, and Linux.
My eclipse tries to compile/build Perl files in my Java project and fails. I installed Perl EPIC just for syntax colouring, how can I get it to ignore errors?
I tried going into Project->Properties->Builders, and uncheck Perl Epic, this didn't change anything.
I'm using Eclipse :Helios Service Release 1
Build id: 20100917-0705
On Windows XP
I have basically the same issue as this question,
How can I set up Eclipse to edit Perl without the runtime checking?
I've been looking into similar issue for quite some time too. Apparently the Epic Perl plugin goes wildly checking anything/folder/file it finds inside the project, so like mine where I have config files, data directories, it goes inside and tries to validate "perl stuff", which evidently is an annoyance: the error log view displays a lot of useless information.
Did you try to uncheck the "Perl Auto Builder" ?
I'm not parsing this sentence in the context of your question: "My eclipse tries to compile/build perl files in my java project and fails."
Are you saying that you are running perl as a java project, and getting the inevitable error message because it is not java? Just wondering why you don't want to have your perl program set up as a perl project possibly referenced by your java project, assuming that that is what you are trying to do.
Generally, when I set up a perl project, I edit its properties and set its includes to match the current directory or local module paths. Assuming that there are self-written modules I must call, and they are not located on this machine (e.g. I wouldn't have FOO::smb on a windows machine -- it makes no sense. When I am developing for linux, I will put all my functions in there for convenience's sake)
In that case, I create a FOO directory in the workspace, and create a dummy FOO::smb module with however many stub functions in it to get me going and let my syntax highlighting and error checkign do their proper jobs for me. If I write dummy subs to match the real modules well enough, I can debug my scripts somewhat before uploading them. I figure that I should be well enough aware of what they are supposed to do anyway.
I will go so far as to dummy out CPAN modules assuming that installing them on my development workstation makes no sense or is impossible. Highlighting and syntax checking are both invaluable tools, and finding a way to make both of them work saves my sanity.
PLDelphi is a Perl project hosted on CPAN. I am currently working on a Delphi application and I am investigating the possibility of adding Perl scripting support and read about PLDelphi.
Ideally, I'd like my application to not require Perl to be installed. PLDelphi claims to support this:
To use PLDelphi from your Delphi
application without need to install
Perl you will need this files in the
main diretory of your application:
PLDelphi.dll - The PLDelphi
library that loads the Perl
interpreter. PLDelphi.pm - Perl
side of PLDelphi. Perl56.dll -
The Perl library in case that you have
Perl built dynamic. PLDelphi_dll.pas -
PLDelphi classes and DLL wrapper.
lib/* - A Perl lib directory with basic .pm files (strict, warnings, etc...)
I am aware of RemObjects PascalScript and embedding Python in Delphi, but in this instance, I am interested primarily in Perl support.
Has anyone used PLDelphi with success? Or have you found other ways to execute Perl scripts from Delphi without the full Perl installation available locally?
EDIT:
To be more clear, I found 1 potential solution and that is using PLDelphi. However, I'd like to know if anyone has used it (last updated in 2004) before, and how well it worked.
I'm also interested in hearing about any other options for embedding a Perl interpreter with Delphi.
You could use Windows Script Host (which comes with VBScript and JScript by default) and install PerlScript from ActiveState.
Sadly PLDelphi isn't updated for XE3 or 64 bits there for won't work with Perl 5.16
I was really looking for a solution that didn't require installing anything on the client. It appears that PLDelphi is not working with ActivePerl 5.10...so I don't believe there is a ready solution to embedding Perl within a Delphi application.
I have an app that I pack into "binary" form using PerlApp for distribution. Since my clients want a simple install for their Win32 systems, this works very nicely.
Now a client has decided that they need to run all unit tests, like in a standard install. However, they still will not install a normal Perl.
So, I find myself in need of a way to package my unit tests for operation on my client's systems.
My first thought was that I could pack up prove in one file and pack each of my tests separately. Then ship a zip file with the appropriate structure.
A bit of research showed that Test::Harness::Straps invokes perl from the command line.
Is there an existing tool that helps with this process?
Perhaps I could use PAR::Packer's parl tool to handle invocation of my test scripts.
I'm interested in thoughts on how to apply either PAR or PerlApp, as well as any thoughts on how to approach overriding Test::Harness and friends.
Thanks.
Update: I don't have my heart set on PAR or PerlApp. Those are just the tools I am familiar with. If you have an idea or a solution that requires a different packager (such as Cava Packager), I would love to hear about it.
Update 2: tsee pointed out a great new feature in PAR that gets me close. Are there any TAP experts out there that can supply some ideas or pointers on where to look in the new Test::Harness distribution?
I'm probably not breaking big news if I tell you that PAR (and probably also perlapp) aren't meant to package the whole test suite and plethora of CPAN-module build byproducts. They're intended to package stand-alone applications or binary JAR-like module libraries.
This being said, you can add arbitrary files to a PAR archive (both to .par libraries and stand-alone .exe's) using pp's -a switch. In case of the stand-alone executable, the contents will be extracted to $ENV{PAR_TEMP}."/inc" at run-time.
That leaves you with the problem of reusing the PAR-packaged executable to run the test harness (and letting that run your executable as a "perl"). Now, I have no ready and done solution for that, but I've recently worked on making PAR-packaged executables re-useable as more-or-less general purpose perl interpreters. Two gotchas before I explain how you can use that:
Your application isn't going to magically be called "perl" and add itself to your $PATH.
The "reuse" of the application as a general purpose perl requires special options and does not currently support the normal perl options (those in perlrun). It can simply run an external perl script of your choice.
Unfortunately, the latter problem is what may kill this approach for you. Support for perl command line options is something I've been thinking about, but won't implement any time soon.
Here's the recipe how you get PAR with "reusable exe" support:
Install the newest version of PAR from CPAN.
Install the newest, developer version of PAR::Packer from CPAN (0.992_02 or 03).
Add the "--reusable" option to your pp command line.
Run your executable with the following options to run an external script "foo.pl":
./myapp --par-options --reuse foo.pl FOO-PL-OPTIONS-HERE
Unfortunately, how you're going to teach Test::Harness that "./myapp --par-options --reuse" is a perl interpreter is beyond me.
Cava Packager allows you to package test scripts with your packaged executables. This is primarily to allow you to run tests against the packaged code before distribution. However the option is there to also distribute the tests and test capability to your end users.
Note: As indicated by my name, I am affiliated with Cava Packager.
Selenium has some nice additional libraries, as long you are using Java to write your tests, e.g. LoggingSelenium. However, these are not usable if you are writing in Perl. How do you normally do proper reporting, possibly with screenshots after every significant step etc.?
Not an ideal answer but have you looked at the Java module on CPAN? You could then use the original Java Selenium libraries such as LoggingSelenium to do your reporting. You'll need to run a Java server with the jar provided by the CPAN Java module (but if you're already using Selenium...)
You could also try Java::Import which might avoid the need to run a server.
TAP::Formatter::HTML produces nice-looking html reports. It does not do screenshots, though.
