28 | Changes in version 1.27: |
29 | ||
30 | * The make rule which prevented bison.simple from being created on | |

32 | \f | |
33 | Changes in version 1.26: | |
4be07551 JT |
34 | |
35 | * Bison now uses automake. | |
36 | ||
37 | * New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>. | |
38 | ||
39 | * Token numbers now start at 257 as previously documented, not 258. | |
40 | ||
41 | * Bison honors the TMPDIR environment variable. | |

44 | |

5c31c3c2 | 50 | Changes in version 1.25: |
df8878c5 RS |
51 | |
52 | * Errors in the input grammar are not fatal; Bison keeps reading | |
53 | the grammar file, and reports all the errors found in it. | |
8c44d3ec | 54 | |
df8878c5 RS |
55 | * Tokens can now be specified as multiple-character strings: for |
56 | example, you could use "<=" for a token which looks like <=, instead | |
57 | of chosing a name like LESSEQ. | |
58 | ||
59 | * The %token_table declaration says to write a table of tokens (names | |
60 | and numbers) into the parser file. The yylex function can use this | |
61 | table to recognize multiple-character string tokens, or for other | |
62 | purposes. | |
63 | ||
64 | * The %no_lines declaration says not to generate any #line preprocessor | |
65 | directives in the parser file. | |
66 | ||
67 | * The %raw declaration says to use internal Bison token numbers, not | |
68 | Yacc-compatible token numbers, when token names are defined as macros. | |
69 | ||
70 | * The --no-parser option produces the parser tables without including | |
71 | the parser engine; a project can now use its own parser engine. | |
72 | The actions go into a separate file called NAME.act, in the form of | |
73 | a switch statement body. | |

75 | Changes in version 1.23: |
76 | ||
4d019228 DM |
77 | The user can define YYPARSE_PARAM as the name of an argument to be |
78 | passed into yyparse. The argument should have type void *. It should | |
79 | actually point to an object. Grammar actions can access the variable | |
80 | by casting it to the proper pointer type. | |

6780ca7a | 82 | Line numbers in output file corrected. |
