custom language plugin: grammar-kit works, plugin doesn't
I have the following grammar:
{
parserClass = "com.first.parser.RulesParser"
parserUtilClass="com.first.parser.RulesParserUtil"
extends = "com.intellij.extapi.psi.ASTWrapperPsiElement"
psiClassPrefix = "Rule"
psiImplClassSuffix = "Impl"
psiPackage = "com.first.plugin.psi"
psiImplPackage = "com.first.plugin.psi.impl"
elementTypeHolderClass = "com.first.plugin.psi.RulesTypes"
elementTypeClass = "com.first.plugin.psi.RuleElementType"
tokenTypeClass = "com.first.plugin.psi.RuleTokenType"
tokens = [
INCLUDE_FILE = '*include-file*'
space = 'regexp:\s+'
comment = 'regexp:[#|//].*'
string = "regexp:\"[^\"]*\"|'[^']*'"
]
}
ruleFile ::= spacing sections
sections ::= [ spacing include_section spacing ]
include_section ::= (INCLUDE_FILE space+ string spacing)*
spacing ::= (space | comment)*
I've tested this in grammar-kit preview with the following test
*include-file* "file1.trd"
*include-file* "file2.trd"
In the deployment of the plugin, i get the following error: RuleTokenType.space expected, got '"file1.trd"'
any tips?

Check out whitespace handling section here:

Thanks Greg. I noticed that the flex generator creates two tokens EOL and WHITE_SPACE. i had my own spacing which was overridden by the WHITE_SPACE that preceded it. Are these two tokens expected? i actually removed WHITE_SPACE to get it working.
