Object

gudusoft.gsqlparser.PowerQueryLexer

public class PowerQueryLexer
extends TCustomLexer

Power Query M-Language lexer (hand-written).

Unlike every other TLexer<Vendor> in this repository this class is NOT generated from a .l file and does NOT consume a *_lex_table.txt DFA table. It exists only to satisfy the TCustomLexer API contract; the actual M-language tokenization runs in PowerQueryTokenizer.

Naming: this file deliberately avoids the TLexer prefix so the project's generated-file hook leaves it alone — see .claude/hooks/protect-generated-files.sh. When (if) the full YACC grammar is ever regenerated, the generated TLexerPowerQuery.java can coexist and PowerQuerySqlParser would flip over.
