5 | |
| 6 | * Russian translation added. | |
| 7 | ||
| 8 | * NLS support updated; should hopefully be less troublesome. | |
| 9 | ||
| 10 | * Added the old Bison reference card. | |
| c33638bb AD |
11 | |
| 12 | * Added `--locations' and `%locations'. | |
| 6deb4447 | 13 | |
| cd5bd6ac AD |
14 | * Added `-S' and `--skeleton'. |
| 15 | ||
| 16 | * Special characters are escaped when output. This solves the problems | |
| 17 | of the #line lines with path names including backslashes. | |
| 18 | ||
| 6deb4447 AD |
19 | * New directives. |
| 20 | `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose', and | |
| 21 | `%debug'. | |

23 | Changes in version 1.28: |
| 24 | ||
| 25 | * Should compile better now with K&R compilers. | |
| 26 | ||
| 27 | * Added NLS. | |
| 28 | ||
| 29 | * Fixed a problem with escaping the double quote character. | |
| 30 | ||

33 | Changes in version 1.27: |
| 34 | ||
| 35 | * The make rule which prevented bison.simple from being created on | |
| 36 | some systems has been fixed. | |
| 37 | \f | |
| 38 | Changes in version 1.26: | |
| 4be07551 JT |
39 | |
| 40 | * Bison now uses automake. | |
| 41 | ||
| 42 | * New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>. | |
| 43 | ||
| 44 | * Token numbers now start at 257 as previously documented, not 258. | |
| 45 | ||
| 46 | * Bison honors the TMPDIR environment variable. | |
| 47 | ||
| 48 | * A couple of buffer overruns have been fixed. | |
| f51dbca1 JT |
49 | |
| 50 | * Problems when closing files should now be reported. | |
| 51 | ||
| 52 | * Generated parsers should now work even on operating systems which do | |
| 53 | not provide alloca(). | |

| 5c31c3c2 | 55 | Changes in version 1.25: |
| df8878c5 RS |
56 | |
| 57 | * Errors in the input grammar are not fatal; Bison keeps reading | |
| 58 | the grammar file, and reports all the errors found in it. | |
| 8c44d3ec | 59 | |
| df8878c5 RS |
60 | * Tokens can now be specified as multiple-character strings: for |
| 61 | example, you could use "<=" for a token which looks like <=, instead | |
| 62 | of chosing a name like LESSEQ. | |
| 63 | ||
| 64 | * The %token_table declaration says to write a table of tokens (names | |
| 65 | and numbers) into the parser file. The yylex function can use this | |
| 66 | table to recognize multiple-character string tokens, or for other | |
| 67 | purposes. | |
| 68 | ||
| 69 | * The %no_lines declaration says not to generate any #line preprocessor | |
| 70 | directives in the parser file. | |
| 71 | ||
| 72 | * The %raw declaration says to use internal Bison token numbers, not | |
| 73 | Yacc-compatible token numbers, when token names are defined as macros. | |
| 74 | ||
| 75 | * The --no-parser option produces the parser tables without including | |
| 76 | the parser engine; a project can now use its own parser engine. | |
| 77 | The actions go into a separate file called NAME.act, in the form of | |
| 78 | a switch statement body. | |

80 | Changes in version 1.23: |
| 81 | ||
| 4d019228 DM |
82 | The user can define YYPARSE_PARAM as the name of an argument to be |
| 83 | passed into yyparse. The argument should have type void *. It should | |
| 84 | actually point to an object. Grammar actions can access the variable | |
| 85 | by casting it to the proper pointer type. | |
| 6780ca7a | 86 | |
| 6780ca7a | 87 | Line numbers in output file corrected. |
