30 | Revision 1.25 2002/02/12 22:46:47 jrm21
|
---|
31 | Allow nested _If_ macros. We now count '(' and ')' characters, so you can now
|
---|
32 | do _If_(_foo_, _If_(_bar_,FOOBAR,FOONOBAR), _If_(_bar_,NOFOOBAR,NOFOONOBAR) )
|
---|
33 | inside a macro file. If you want to display a bracket, you can escape it.
|
---|
34 | Previously we had assumed that a ',' marked the end of a toplevel argument.
|
---|
35 |
|
---|
36 | Revision 1.24 2001/01/25 18:26:44 cs025
|
---|
37 | Included CORBA branch for first time
|

47 |
|
---|
48 | Revision 1.15 1999/09/24 02:25:35 rjmcnab
|
---|
49 | removed limitation on the number of arguments that a macro can have
|
---|
50 |
|
---|
51 | Revision 1.14 1999/09/07 04:57:41 sjboddie

54 | Revision 1.13 1999/08/31 07:59:11 rjmcnab
|
---|
55 | Generalised spaces to unicode spaces, added ability to automatically detect
|
---|
56 | whether the input file is Unicode or UTF-8 and read the file in the
|
---|
57 | appropriate way, and improved the error messages slightly.
|
---|
58 |

|
---|
62 | Revision 1.11 1999/07/21 07:26:30 rjmcnab
|
---|
63 | Added more operators to _If_, changed quoting of parameters so that
|
---|
64 | ' can be used to quote but it is removed, and made slight optimisation
|
---|
65 | so that macros that don't contain other macros aren't expanded.
|
---|
66 |
|
---|
67 | Revision 1.10 1999/03/01 20:39:54 sjboddie
|
---|
68 |

|
---|
72 |
|
---|
73 | Fixed bug in _If_ when value being tested was only one character
|
---|
74 | long (e.g. "0" or "1")
|
---|
75 |
|
---|
76 | Revision 1.8 1999/02/28 23:15:29 rjmcnab
|
---|
77 |

|
---|
79 |
|
---|
80 | Revision 1.7 1999/02/08 01:26:11 rjmcnab
|
---|

|
---|
85 |
|
---|
86 | Added a method to determine whether a macro has been defined.
|
---|
87 |
|
---|
88 | Revision 1.5 1999/01/19 01:38:12 rjmcnab
|
---|
