I'm restarting a editing project that could take advantage of using
"regular expressions".

I had stated using Kate for the project.

I'm reviewing my regular expression related web searches. It would be
helpful if I could find a _single_ document that made comparison
between/among Kate, Kwrite, and Katepart. [e.g. package goals]

My "universe of discourse" is a collection of references discussing the

A significant number of which mention Kate *or* Kwrite *or* Katepart.
I need to understand the entity goals of Kate, Kwrite, and Katepart.
I.E. In a discussion of "regular expressions", does it matter which of

Description-md5: ab2572368eb6cf239ac558f6cd35a97c
Description-en: powerful text editor
Kate is a powerful text editor that can open multiple files simultaneously.
.
With a built-in terminal, syntax highlighting, and tabbed sidebar,
it performs as a lightweight but capable development environment.
Kate's many tools, plugins, and scripts make it highly customizable.
.
Kate's features include:
.
* Multiple saved sessions, each with numerous files
* Scriptable syntax highlighting, indentation, and code-folding
* Configurable templates and text snippets

other text tools.

Package: ktexteditor-katepart
Description-md5: 3162e86e5e7045f0a5f650908df08a6f
Description-en: provide advanced plain text editing services
The KTextEditor interfaces - also called KTE interfaces - are a set
of well-defined interfaces which an application or library can
implement to provide advanced plain text editing

Sorry, but I do not understand the meaning of your words:
"universe of discourse"
"entity goals"

And I am confused by this sentences:
"A significant number of which mention Kate *or* Kwrite *or* Katepart."
"In a discussion of "regular expressions", does it matter which of those packages is referred to?"

Maybe I need more sleep. Apologies. I hope someone understands and can answer your questions.

I am guessing you are talking about: https://docs.kde.org/stable5/en/kate/kate/regular-expressions.html https://docs.kde.org/stable5/en/kate/katepart/regular-expressions.html https://docs.kde.org/stable5/en/kate/kwrite/index.html (I presume kwrite does not support regular expressions)

If I have understood your query (which seems unlikely), is the answer:

Kwrite does not support regular expressions whil eKate and Katepart support the same regular expressions as defined in https://docs.kde.org/stable5/en/kate/katepart/regular-expressions.htm

George.

About the packages you mention I can't say much. If you have more
concrete regular expression questions, I'm happy to chime in.

Got it. Then David Wirght's answer seems to be the most appropriate.

Most (programmer's) text editors (from the many variations of vi,
Emacs, and, yes, Kate and its friends) do support regular expressions.

Note that regular expressions come in slightly different flavours.
Going by Kate's documentation [1] on this topic they seem to be
PCRE or a variant thereof.

Err, did you notice the bit in that reference that says: "It documents
regular expressions in the form available within KatePart, which is not compatible with the regular expressions of perl"? Note that PCRE stands
for Perl Compatible Regular Expressions.

Thanks for pointing that out. I missed that (I searched for PCRE in the
page), so my assessment was due to cursory eyeballing (that's why I
wrote "seem to be...".

And note PCRE is not Perl's regexps, but just "inspired by". They
converged and diverged over their respective histories. To get an
idea of the current situation, perhaps [2] is relevant.

I think there is a universal human desire to try to avoid looking stupid.
I wonder sometimes if people are afraid that asking a simple question will make them look stupid.

This can then lead to questions with extra layers of pontification and obfuscation and passive voice and intransigence and XY questions.

The problem with this is that it just makes it so much more difficult to help, and generates long confusing threads, and wading through all this is
a less pleasant experience for everyone than just answering a simple question.

I can "sorta" generally accept those three paragraphs.

The question could have been something like: "I want to learn about using regular expressions for manual text editing. I'm thinking to use Kate,
Kwrite or KatePart. Does it matter which of those I use?"

That does *NOT* express *MY* question!!!

Answer: No.

That answer is demonstrably *WRONG* for at least two reasons:
1. Both Kate and Kwrite exist for a reason.
"What reason" is left as an exercise for the student ;}
2. Is KatePart used by *any* editor other than Kate and Kwrite?

Other responses to my question quoted documentation addressing

an editing project that could take advantage of using "regular expressions".

I had already seen some but not all of the references.

I'm still interested in

a _single_ document that made comparison between/among Kate, Kwrite
and Katepart.

Thanks to all who responded.

It was evidently clear enough to *YOU* that you could [and *did]

Asking a vague a confusing question and then strongly emphasing that
what people have gone to the trouble of responding to you is not what

You seem to always want one document taylor-made to your questions, some
holy grail of documentation that will answer all you questions (even the
ones that you haven't even though of yet).

It most cases that's not how it's going to work: you'll have search
several documents, and piece together from them what you really want.
Even in cases when there is, for example, a very compreehensive book on
a subject (like some books on programming languages), it still might not address every single point you'd like to. And it will cover some things
that are not relevant to you.

Moreover, it is just lazy to expect people to search the web for you. If
you have some specific question, it is fine to ask, but you could've
search yourself for the vague questions you had, and found out the broad answers by yourself.
