This page is the starting point for developers looking to contribute to and/or modify Daffodil.
In the side bar on the left you should see a variety of child pages for various developer topics.
A few smaller topics are covered directly here.
Microsoft Windows Users
Daffodil depends on Unicode support. Some MS-Windows versions do not come with Unicode support by default. Daffodil has tests that make use of Japanese Kanji characters, so requires the Japanese Language Pack be installed.
Test Coverage and Code Analysis Reporting
Each commit to the daffodil repository automatically runs tests and code analysis.
The test coverage analysis report is available here: https://codecov.io/gh/apache/incubator-daffodil
The code analyzer analysis report is available here: https://sonarcloud.io/dashboard?id=apache_incubator-daffodil
