Note: This page is hopelessly outdated and dates back several years to when I was maintaining kio-locate. A new version of this tool, that has been ported to KDE4, can be found at http://websvn.kde.org/trunk/playground/ioslaves/kio-locate/.

kio-locate: A KDE I/O Slave

Probably you know the locate command for doing quick file searches. kio-locate enables you, to start such a search from konqueror.

To search using locate you don't have to switch to a prompt.
The search results are shown to you, as if you were in a directory. Any found file is just one click away.
You could e.g. move all found files using Drag & Drop.
And all that's possible from practically any KDE program, that can open files.

Perhaps you should just take a look at the screenshots.

Unfortunately, I currently don't have the time to maintain kio-locate.

Many thanks to Tobi Vollebregt who has been improving kio-locate as a participant of Googles "Summer of Code". Thank you very much!

	kio-locate 0.4.2tvo0.1	2005/07/14	Tobi Vollebregt
+	Directory collapsing if pattern matches the directory part of a path.
+	Entries for searching within directories and entries for plain browsing of the directories.
+	Added full wildcard support in all patterns (after discussion this seemed to be more appropriate than full regexp support for `locate:').
+	Added full regexp support in the filtering patterns with the `rlocate:' protocol.
+	A case sensitivity setting in the config page.
+	A `config succesfully updated' or `config unchanged' message is displayed after closing the config dialog.
+	Different icons for normal and collapsed directories.
+	Configurable RegExp filtering, using a white list and a black list.
*	Fixed searches within a directory other than root (/).

*	Number of hits displayed in front of a directory, is now exactly the number of entries you'll see after you click that entry.
*	`locater:help' now actually works.
*	Updated to the newest version of bksys.

	kio-locate 0.4.2	2005/05/22	Armin Straub
*	Removed stupid bug inverting case sensitivity.

	kio-locate 0.4.1	2005/05/21	Armin Straub

	kio-locate 0.4.0	2005/04/10	Armin Straub
+	Using scons and bksys instead of autotools and the like. This saves both - a lot of space (around 500kb) and lots of time when developing (thanks to Nagy Thomas for his help). Read INSTALL for a quick guide.

*	Use the locater protocol which uses standard Urls for more complex tasks and keep the locate protocol for simple queries.

+	Added a locate search to konquerors list of web shortcuts. This enables you to select locate as the default search engine in konqueror. (Whenever you enter a nonsense url then, konqueror will use locate to search for this "nonsense".)

	kio-locate 0.3.0	2004/11/01	Armin Straub
*	Filtering by regular expressions is now possible: You can use "locate:pattern [!]regexp ..." now. pattern uses standard locate syntax followed by regexps that may be preceded by ! meaning that they shouldn't match.

	kio-locate 0.2.1	2004/10/22	Armin Straub
+	Added french translation (thanks to Laurent Rathle).
*	Included stdlib.h correctly (previously preventing kio-locate to compile on some machines).

	kio-locate 0.2.0	2004/10/15	Armin Straub
*	Complete rewrite.
*	Works with KDE 3.3.
+	Displays detailed information in Konqueror (not just filenames).
+	Enabled patterns like the ones used for locate. kio-locate (0.1.1-1) -- Michael Schuerig
*	Corrected URL prefix ("file:" instead of "file:/").

Some TODOs

	Short Term

	Mid Term
+	Add kio-locate to kde-extragear.
+	Translations needed. Contact Håvard Dahle for Norwegian translation.
+	Support searches on remote servers via ssh. A possible search could then look like "locate://username@server:port pattern". (Suggested by Ferdinand Gassauer)

	Ideas
+	Some kind of first start screen?
+	Check out beagle-query which was said to behave similar to command line locate. (Benjamin Kudria)
+	Use other backends like kat?

How to use this?

You can use kio-locate mostly as you use locate. Instead of typing

$ locate pattern

at a prompt, you start the search with kio-locate directly in konqueror. You just enter locate:pattern as the address.

New: Configure kio-locate

Starting with version 0.4.0 you can configure kio-locate by entering locater:config in konqueror's adress bar (note the r).

A normal search using locate:pattern is case insensitive. But if your search contains upper case characters, the search switches to case sensitivity. You can change this behaviour using locater:config.

How to write Patterns

Furthermore you can't use a backslash as the last character of your query. O.k. you can, but KDE will ignore it. In such a case you can quote your pattern: Write locate:"servicemenus/" rather than locate:servicemenus/.
A search as e.g. locate:~/*.doc works as you might expect. This means that ~/ and ~user/ are expanded correctly at the beginning of the pattern.
In older versions of KDE you can't use a star (*) for a pattern in konqueror. Therefor every plus (+) in a search is used just as a star (*) is. Instead of locate:*.html you may also type locate:+.html.
Should you need to use a plus in your search you have to escape it with a backslash. Instead of locate:g++ you have to use locate:g\+\+.

New: Using Filters

Often you will get lots of results using locate. To filter your search you could use

$ locate kdeprint | grep -v apidocs | grep lib

on the command line to find those files matching kdeprint that don't contain api-docs but lib.

Starting with version 0.3.0 kio-locate has builtin support for such filtering. You can e.g. use locate:kdeprint !api-docs lib to get the same results as above.

You can use arbitrarily many filtering expressions. Those that should not match are prepended by !. To use regular expressions you can use rlocate instead of locate as the protocol.

You can add arbitrary filters to a white- resp. blacklist (using locater:config). This way you can restrict your search to certain folders generally or exclude single directories. If you e.g. replace . by /home/. in your whitelist you will only find files under /home afterwards.

Using this as the default search engine

Since version 0.3.1 you are enabled to select kio-locate as konquerors default search engine (under Web Shortcuts). Whenever you enter an url then, that konqueror can't deal with, a search using locate will be started.

So you can just enter a filename and konqueror will search for it. This saves you the characters needed for the usuallay prepended locate:.
