EmacsEpl

It seems that you can use Perl in a similar way as Python as an extension language (see PyMacs). beppu (Journeyer) wrote in his essay “Transcending Language Bias in Scriptable Applications” [1], that a perl module called `Emacs::EPL` exists. The Perl interpreter is executed as a subprocess, and interprocess communications between the two is accomplished via pipes. It seems, however, that this does not free you from using Lisp – much like PyMacs, you still need to know the One True Programming Language – EmacsLisp.

Experiences, anyone?

non-standard installation proceedure

The installation proceedure is unusual for a perl module, and it’s essential to read the README file carefully.

automated install is broken: "make test" stage is buggy

At present, installation of Emacs::EPL is reported to be failing on many popular platforms according to cpantesters.perl.org.

It’s possible that these reports are misleading, however, because the test platforms may simply not have emacs installed and configured correctly.

The “make test” stage fails at present on Kubuntu GNU/Linux on AMD64, using perl 5.8.7 with GNU Emacs 21.4.1 (With “M-x server-start” done manually, though it’s not clear if that should matter).

It hangs after displaying the error message:

   exec: No such file or directory at /home/doom/End/Slot/Emacs-Perl/Emacs-EPL-0.7/blib/lib/Emacs/EPL.pm line 671.

As a result of these difficulties, automated installation of Emacs::EPL (e.g. using CPANPLUS) essentially doesn’t work.
