----------
|
|
|
|
Changes in version 1.28b:
|
|
|
|
* the input and the output files has automatically a similar extension.
|
|
|
|
* Russian translation added.
|
|
|
|
* NLS support updated; should hopefully be less troublesome.
|
|
|
|
* Added the old Bison reference card.
|
|
|
|
* Added `--locations' and `%locations'.
|
|
|
|
* Added `-S' and `--skeleton'.
|
|
|
|
* `%raw', `-r', `--raw' is disabled.
|
|
|
|
* Special characters are escaped when output. This solves the problems
|
|
of the #line lines with path names including backslashes.
|
|
|
|
* New directives.
|
|
`%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
|
|
`%debug'.
|
|
|
|
Changes in version 1.28:
|
|
|
|
* Should compile better now with K&R compilers.
|
|
|
|
* Added NLS.
|
|
|
|
* Fixed a problem with escaping the double quote character.
|
|
|
|
* There is now a FAQ.
|
|
|
|
Changes in version 1.27:
|
|
|
|
* The make rule which prevented bison.simple from being created on
|
|
some systems has been fixed.
|
|
|
|
Changes in version 1.26:
|
|
|
|
* Bison now uses automake.
|
|
|
|
* New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
|
|
|
|
* Token numbers now start at 257 as previously documented, not 258.
|
|
|
|
* Bison honors the TMPDIR environment variable.
|
|
|
|
* A couple of buffer overruns have been fixed.
|
|
|
|
* Problems when closing files should now be reported.
|
|
|
|
* Generated parsers should now work even on operating systems which do
|
|
not provide alloca().
|
|
|
|
Changes in version 1.25:
|
|
|
|
* Errors in the input grammar are not fatal; Bison keeps reading
|
|
the grammar file, and reports all the errors found in it.
|
|
|
|
* Tokens can now be specified as multiple-character strings: for
|
|
example, you could use "<=" for a token which looks like <=, instead
|
|
of chosing a name like LESSEQ.
|
|
|
|
* The %token_table declaration says to write a table of tokens (names
|
|
and numbers) into the parser file. The yylex function can use this
|
|
table to recognize multiple-character string tokens, or for other
|
|
purposes.
|
|
|
|
* The %no_lines declaration says not to generate any #line preprocessor
|
|
directives in the parser file.
|
|
|
|
* The %raw declaration says to use internal Bison token numbers, not
|
|
Yacc-compatible token numbers, when token names are defined as macros.
|
|
|
|
* The --no-parser option produces the parser tables without including
|
|
the parser engine; a project can now use its own parser engine.
|
|
The actions go into a separate file called NAME.act, in the form of
|
|
a switch statement body.
|
|
|
|
Changes in version 1.23:
|
|
|
|
The user can define YYPARSE_PARAM as the name of an argument to be
|
|
passed into yyparse. The argument should have type void *. It should
|
|
actually point to an object. Grammar actions can access the variable
|
|
by casting it to the proper pointer type.
|
|
|
|
Line numbers in output file corrected.
|
|
|
|
Changes in version 1.22:
|
|
|
|
--help option added.
|
|
|
|
Changes in version 1.20:
|
|
|
|
Output file does not redefine const for C++.
