Release 2.0 of xp
|
||
|
|
|
||
|
|
xp started as a filter to simply display stdin in an Athena text
|
||
|
|
widget. It grew to be a more general file displayer with an emphasis
|
||
|
|
on ease of browsing and searching, but I've tried to keep its interface
|
||
|
|
(and implementation) simple and make it useful in shell scripts.
|
||
|
|
|
||
|
|
xp tries to be reasonably efficient in use of memory when displaying
|
||
|
|
large files, given that the text widgets requires the whole file to be
|
||
|
|
in memory, by using a read-only text widget and freeing memory when a
|
||
|
|
file is no longer displayed (so if you go back to a previously
|
||
|
|
displayed file it gets re-opened).
|
||
|
|
|
||
|
|
xp incorporates Henry Spencer's implementation of egrep style regular
|
||
|
|
expression matching. The xp distribution includes that part of the
|
||
|
|
regexp distribution which it requires.
