Exercism exercises in Lisp
Please be familiar with the contributing guide in the x-api repository. This describes how all the language tracks are put together, as well as details about the common metadata, and high-level information about contributing to existing problems and adding new problems.
Feel free to file any issues at https://github.com/exercism/xlisp/issues for problems of any size. Feel free to report typographical errors or poor wording for example. You can greatly help improve the quality of the exercises by filing reports of invalid solutions that pass tests or of valid solutions that fail tests
Direct contributions to the Common Lisp code in xlisp are always welcome. Refer to the Getting Started Guide for the Common Lisp track to get your environment set up if needed.
New exercises or changes to existing ones can be submitted via a pull request. You will need a GitHub account and you will need to fork exercism/xlisp to your account. See GitHub Help if you are unfamiliar with the process.
A list of exercises yet to be created is in issue #23. This might be a great place to get started.
All new exercise submissions should contain not only the test file,
but the stub of the "production code" (containing the defpackage and
in-package forms), and a file example.lisp which contains an
example implementation.
Before submitting a new exercise please ensure that it passes the
Travis build. This build will run all exercises on many Common Lisp
implementations. To run the build yourself on your implementation load
bin/xlisp-test.lisp and then evaluate (xlisp-test:full-build).
CIM is a tool for working with several Common Lisp implementations at the same time. Allowing for easy switching between them and for consistent usage of them from the command line. It is recommended that one installs CIM and several implementations.
If CIM is installed then running all the tests for one implementation can be done with (this will return with a non-zero error code if there are problems):
cl -f bin/xlisp-test.lisp -e '(xlisp-test:travis-build)'
To run all the tests for all the implementations use this command line:
cim for all do -f bin/xlisp-test.lisp -e '(xlisp-test:travis-build)'
The example implementation should use nothing outside of the Common Lisp specification. It should be well designed and not too clever. (Save the clever implementation for your submission on Exercism.io.)
