* NOTES:
|
|
* this lex script used to use characters also in use
|
|
* by strftime() (which we want to use for custom
|
|
* time formats in replies and templates). to circumvent
|
|
* this we have to play a little bit with states.
|
|
*
|
|
* these are the characters we also want to use in the
|
|
* %D time customizer:
|
|
*
|
|
* %a %A %b %B %c %C %d %H %I %j %m %M %p %S %w %x %y %Y %Z
|
|
*
|
|
* you can use these characters too, but don't forget to
|
|
* prepend them with the <S_NORMAL> state.
|
|
*
|
|
* also there is also work around for resetting the state
|
|
* (firsttime variable). this assumes that yylex() will
|
|
* always return to S_NORMAL after quote fmt parsing is
|
|
* done.
