PsiGen Generates an expression which checks whether a lookahead in a given set of terminals @param first set of terminals @param printer Generates statement that advances lexer @param specialChecking @param outputStream

Returns of terminal occurrences for nonterminal pre-check.

Generates parser body for this level @param helper @param printer

Pre-check expected symbols as first step of non-terminal parsing, it will fail fast and provide all possible symbols instead of only these which are required. When used in conjunction with may help you control which expected tokens are propagated.

inserts underscores between words and converts name to uppercase. @param name

Rule for abstract nonterminals which do not have a defining rule. Current implementation is such that FIRST and FOLLOW of an abstract rule always contain an epsilon string. This means, e.g., that error handling will skip abstract nonterminals

Base class for rules with multiple occurring subrules

Generates getChildRole for OrRule. @param printer Adds all labels that are defined in the rule to the list @param list Determines whether this rule's FIRST contains an epsilon string Returns an ordered list of "phantoms" that are hanged on this rule's creation @return null if no phantoms can be reasonably hanged by this rule parsing Calculates a FIRST set (without an epsilon string) @param result a set of TerminalOccurrence @see TerminalOccurrence Adds set of Symbols (terminals or nonterminals) that may start parsing result of the rule. @param result

Adds nonterminal tails that are generated by this rule.

HashSet of NonterminalTails

Invokes the Parser Generator. Expected parameters (task items with metadata ParameterName equal to these): • Inputs, multiple input files to process. Metadata: • • FullPath — full path to the input file. • OutputFolder — the single folder to write all outputs into. Metadata: • • FullPath — full path to the folder. • DontCache — do not use distributed cache, if present. • DistributedCacheSettings — allows to turn on network upload.

This complies with the ProxyToSolutionCompiledTask calling convention.

Scans through the item group and removes any items that fall under the given folder. Note: you should not be using the same item group for input and output, as the output contributes to the item group but would not replace it.
