37 | Changes in version 1.27: |
38 | ||
39 | * The make rule which prevented bison.simple from being created on | |
40 | some systems has been fixed. | |

42 | Changes in version 1.26: | |
4be07551 JT |
43 | |
44 | * Bison now uses automake. | |
45 | ||
46 | * New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>. | |
47 | ||
48 | * Token numbers now start at 257 as previously documented, not 258. | |
49 | ||

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

85 | ||
4d019228 DM |
86 | The user can define YYPARSE_PARAM as the name of an argument to be |
87 | passed into yyparse. The argument should have type void *. It should | |
88 | actually point to an object. Grammar actions can access the variable | |
89 | by casting it to the proper pointer type. | |

6780ca7a | 91 | Line numbers in output file corrected. |
