4 | Changes in version 1.28a: | |
5 | ||
6 | * Russian translation added. | |
7 | ||
8 | * NLS support updated; should hopefully be less troublesome. | |
9 | ||
10 | * Added the old Bison reference card. | |
11 | ||
12 | * Added `--locations' and `%locations'. | |
13 | ||
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 | ||
19 | * New directives. | |
20 | `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose', and | |
21 | `%debug'. | |
22 | \f | |
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 | ||
31 | * There is now a FAQ. | |
32 | \f | |
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: | |
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. | |
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(). | |
54 | \f | |
55 | Changes in version 1.25: | |
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. | |
59 | ||
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. | |
79 | \f | |
80 | Changes in version 1.23: | |
81 | ||
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. | |
86 | ||
87 | Line numbers in output file corrected. | |
88 | \f | |
89 | Changes in version 1.22: | |
90 | ||
91 | --help option added. | |
92 | \f | |
93 | Changes in version 1.20: | |
94 | ||
95 | Output file does not redefine const for C++. |
