[SLI-0135] Warning messages are shown as errors

[thewillyhuman]

Introduction

Warning messages are shown as follows:

error[W002]: base has been set but not used
--> ../../test/assets/incorrect_schema_big_schema_2.shexl:10:5
        |
10      | base <google.es>
        |      ^ the base `<google.es>` definition is set but not used

Where says error should say warning.

Proposed solution

This error message is configured here:

shex-lite/src/compiler/es/weso/shexlc/internal/errorhandler/Warn.scala

Line 87 in 8ac6bb7

s"${Console.YELLOW}error[${ttype.getCode}]: ${Console.RESET}${ttype.getDescription}"

If we change that error message the issue would be fixed.
