|
|---|
| 15 | tidied a few things up. documentaction::define_external_macros now
|
|---|
| 16 | resets the "c" arg if it's set to something stupid by the .xx suffixes
|
|---|
| 17 |
|
|---|
| 18 | Revision 1.5 1999/06/16 03:10:49 sjboddie
|
|---|
| 19 | define_internal_macros() now sets _pagetitle_ macro to document's title
|
|---|
| 20 | (including parents of current document)
|
|---|
| 21 |
|
|---|
| 22 | Revision 1.4 1999/06/15 01:55:29 sjboddie
|
|---|
| 23 | - got text highlighting working
|
|---|
| 24 | - got multiple collections working (now outputs error message if an
|
|---|
| 25 | attempt is made to get a document when the "c" arg isn't set.
|
|---|
| 26 |
|
|---|
| 27 | Revision 1.3 1999/06/08 04:29:37 sjboddie
|
|---|
| 28 | added argsinfo to the call to check_cgiargs to make it easy to set
|
|---|
| 29 | args to their default if they're found to be screwed up
|
|---|
| 30 |
|
