This is an implementation of E programming language in Common Lisp.
There are as yet no releases, but the source is available in a Git repository:
The full E language is implemented, by compilation to Common Lisp and execution by the underlying CL implementation. The libraries are incomplete.
E-on-CL requires E-on-Java for:
- Support for the E parser (which is written in ANTLR.
- Parts of the library implementation (those
emakers which are not different)
There is Updoc and a REPL, written in CL.
IO is limited to:
- Writing text to stdout and stderr.
- Reading and writing files as text from absolute pathnames.
- TCP sockets, as octets or a small selection of character encodings.
- Unsafely accessing the underlying Lisp system.
Differences from E-on-Java
Support for EIO and
throw() and CatchExpr have been changed to reduce information leakage: see sealed throw.
makeEProxyResolver is replaced with
makeProxy, a safer interface.
Updoc does not ignore the return value of expressions when the updoc script omits them.
- A Common Lisp implementation.
E-on-CL is designed to be portable, but requires many nonstandard features for full operation. I use SBCL, and therefore its support is the most complete. Other implementations E-on-CL includes some support for, roughly in order of completeness, are Clozure CL, CMUCL, ABCL, CLISP, LispWorks, and Allegro CL.
Whether E-on-CL works on any given implementation (other than SBCL) will vary as I make changes. If it doesn’t run on an implementation you’d like to use, please let me know and I’ll see what can be done about it.
- The asdf-installable libraries bordeaux-threads, cl-ppcre, cl-yacc, cl-fad, genhash, rt, and trivial-garbage.
- An existing E-on-Java installation.
- One of either:
perl, if you wish to use the standard startup script
