[YANGTOOLS-1089] Cannot parse yang files containing plus

Wed, 26 Aug 2020 16:05:29 +0000

We have tried to use:

dependency>

<groupId>org.opendaylight.yangtools</groupId>

<artifactId>yang-parser-impl</artifactId>

</dependency>

<groupId>org.opendaylight.yangtools</groupId>

<artifactId>yang-parser-api</artifactId>

</dependency>

<groupId>org.opendaylight.yangtools</groupId>

<artifactId>yang-model-api</artifactId>

</dependency>

and even 3.0.5

Problem appeared for example ( but is not limited to since we tried same for description)

unquoted string for default like this:

      leaf timeOffset {
            type string {
                length "5..6";
            }
           description "The time offset from UTC";
            default +00:00;
        }

We will get the following exception when parsing.

*no* further _formatting_ is done here

Is it possible to fix in any of the above versions since 4.x has major refactoring?

We cannot continue to parse our yang model files due to this issue. It is a stopper.
