Change my-function-name-- to my_function_name, and optimizer renames. 1999-02-13 18:22:53 -05:00			`* gramparse.h`
First cut at full support for OUTER JOINs. There are still a few loose ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED! 2000-09-12 17:07:18 -04:00			`* Declarations for routines exported from lexer and parser files.`

Scanner performance improvements Use flex flags -CF. Pass the to-be-scanned string around as StringInfo type, to avoid querying the length repeatedly. Clean up some code and remove lex-compatibility cruft. Escape backslash sequences inline. Use flex-provided yy_scan_buffer() function to set up input, rather than using myinput(). 2002-04-20 17:56:15 -04:00			`* $Id: gramparse.h,v 1.21 2002/04/20 21:56:15 petere Exp $`

Another PGINDENT run that changes variable indenting and case label indenting. Also static variable indenting. 1997-09-07 22:41:22 -04:00			`extern int yyparse(void);`
plpgsql's private copy of xlateSqlType was out of sync. Again. This is clearly not maintainable, so dike it out in favor of calling the real version in the backend's gram.y. 2001-02-08 22:26:28 -05:00			`extern char xlateSqlFunc(char name);`

Functions live in namespaces. Qualified function names work, eg SELECT schema1.func2(...). Aggregate names can be qualified at the syntactic level, but the qualification is ignored for the moment. 2002-04-09 16:35:55 -04:00			`extern List SystemFuncName(char name);`
pgindent run on all C files. Java run to follow. initdb/regression tests pass. 2001-10-25 01:50:21 -04:00			`bool exprIsNullConstant(Node *arg);`
Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 01:26:15 -05:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 12:46:40 -05:00			`#endif /* GRAMPARSE_H */`
