Hi everybody, my name is Ken Fallon and today I want to give you a quick tip about the
|
|
Kate text editor, so K-A-T-E Kilo Alpha Tango Echo.
|
|
It is a text editor that comes with KDE, I don't know 100% sure if it's the fault, but
|
|
it's definitely one that I install pretty much in every computer.
|
|
It doesn't seem to text them that much, it's a kind of lightweight enough text editor.
|
|
But it has a few things that for me makes it absolutely fantastic.
|
|
One of those is the ability to do search and replace.
|
|
For example, you go control or find replace and at the bottom it's got to replace words
|
|
or plain text, so slash N would replace anything with slash N. Escape sequences would replace
|
|
slash N would treat that as a new line and you can do regular expressions, but that's
|
|
not actually what I want to talk to you about today.
|
|
If you go into tools, if you actually hold down control and the backslash key, it pops
|
|
up the text filter option.
|
|
What that will allow you to do is enter commands on the highlighted text, so if you've highlighted
|
|
a series of lines and you want it sorted, so then you can press control and backslash
|
|
and type sort, and it will sort that list for you within the text editor.
|
|
That might not be that interesting to you, but what you basically can do is then you
|
|
say doc and grep and other programs within your text, within the text file that you're
|
|
working on, and that is actually really rather awesome.
|
|
So if I'm looking down my history here, I have oc, space, dash, capital F, quote, forward
|
|
slash, quote, space, quote, open squiggly bracket, print space, dollar three, close squiggly
|
|
bracket, single quote again.
|
|
And what that one does is this will print out the third line of a column.
|
|
So this is handy if you open up a text file, a log file or something, and you think and
|
|
grep for the word error for error, or for instance, and then you determine what the format
|
|
is, you're only interested in finding the identifiers, and that's in column three.
|
|
So then you can run alkanat and it's just handier than having to save it out and then
|
|
build your pipeline.
|
|
This is kind of an easy way to do it.
|
|
It also though, with that option, you have the option to emerge standard output and standard
|
|
error, or you have the option to copy the results, so it goes into your keyboard and
|
|
are into your clipboard and is available for all the stuff.
|
|
So to enable that, sometimes it gets disabled from time to time after an update and I struggle
|
|
to find out where it is.
|
|
So the reason I'm doing this show is so I will know that I've done a show about it and
|
|
I can go back and find out where to turn it back on and how you turn it back on settings
|
|
and configure Kate and then go into under applications plugins and the plugin you need
|
|
to re-enable is text filter and the comment is easy text filtering.
|
|
There are all sorts of things that you can turn on for plugins.
|
|
There's plugins and extensions, I'm not 100% sure what the difference between the two
|
|
is.
|
|
One is an application component and the other is an editor component, but I'm sure it
|
|
makes sense to the guys.
|
|
The one I use from time to time is XML validation, but to be honest, I prefer to do that straight
|
|
on the command line.
|
|
So that's a small tip, text filtering in your text editor.
|
|
If your text editor of choice does something similar to this and if you've known about
|
|
this for years, feel free to record a show because it might be obvious to everybody how
|
|
to enable it in their show.
|
|
