Eastwood is a Clojure lint tool. It analyzes Clojure source code in
Leiningen projects, reporting things that may be errors.
Installation instructions are in the documentation here:
https://github.com/jonase/eastwood/#installation--quick-usage
The previous release was in January 2014. Updates since then are described
in the change log here:
https://github.com/jonase/eastwood/blob/master/changes.md#changes-from-version-010-to-011
Probably the most noticeable changes for Eastwood users will be the errors
if namespace/file name inconsistencies are found, and the reduction in bad
reflection warnings.
Below is the description Eastwood from the January 2014 release:
For example, did you know that if you use clojure.test to write tests, and
have multiple deftest definitions in the same namespace with the same name,
then the tests in all but the last deftest will never be run, whether those
tests would pass or fail? Eastwood can find those duplicate names, as well
as other occurrences of the same Var name defined more than once.
Eastwood can also warn about misplaced doc strings, calling deprecated
functions or Java methods, expressions that are suspicious because they
always return the same value (e.g. (= expr) is always true), expressions
whose return value is not used and appear to have no side effects, and a
few others. See the documentation linked above for a complete list.
Jonas Enlund wrote the original version of Eastwood with the help of
several other contributors. Version 0.1.1 is an update by Jonas, Nicola
Mometto, and myself. It uses the new Clojure contrib libraries
tools.reader for reading the code, and tools.analyzer and
tools.analyzer.jvm for parsing the source into abstract syntax trees,
making it straightforward to write many of the linters. Thanks especially
to Nicola Mometto for tireless enhancements and bug fixes to those
libraries.
You can file issues on the Github issue tracker if you encounter problems,
but please read the "Known Issues" section of the documentation before
filing problems. Several issues have already been discovered, and their
causes documented, while testing Eastwood on most of the Clojure contrib
libraries, Clojure itself, and over 35 other open source libraries.
Go squash some bugs!
