This plugin uses ANTLR to generate a parser for the YAML serialization format. Apart from the hand written lexer, all other parts of the plugin use standard ANTLR tools, such as
The plugin requires
4.7.1
or later (antlr4
), andantlr4-cpp-runtime
or libantlr4-runtime-dev
). If packages for those libraries are not available for your system, you can install them manually. For more information about that please take a look at ANTLR’s homepage and at the ReadMe of the ANTLR C++ runtime.

will produce a plain scalar containing a tab character followed by the text value
. The correct behavior would be to report an error, since YAML does not allow tab characters in indentation.
Visualized error messages (containing ^
markers) might not point to the correct error location, if the input contains tabs or unicode characters with a length other than 1
.
