Title: Length of selected text
Post by: zdena on May 10, 2019, 08:27:25 am
Hello,
if I make a selection of text in the code, can I get somehow the length (number of selected characters) of the selection?

At the moment I don't think it is possible.

What would you like to do with it?
How would you like to get it?
I think it would not be to difficult to add a script binding...

This would be a quite easy fix:
Code

Does something speaks against this?

Yes, it is getting too long and it doesn't convey that it is length.

After the previous change in this area there was a discussion to make this thing configurable with some kind of a formatting string.

@BlueHazzard: It was whole morning fight. I lost the battle with automatic patching :( , but I solved it manually :) . Next the C::B sources compiling was hard - especially battle with libexchndl.
But the result: Yes, your solution works pretty good  ;) Thank you

To come back to this. The easiest way to make it configirable would be to expose a printf formatter string and give the user the information that
Code
%1$03d
is the current line
Code
%2$03d
is the current column
Code
%3$03d
is the current selection

so he can write
Code
 Line: %1$03d Col:%2$03d Sel:%3$03d
or
Code
 Sel: %3$03d | Line:%1$3d
or whatever by himself... Of course here he has some way to screw up, probably some sanity checking can be introduced, but i think this is the fastest and most flexible way.

A other possibility would be to give him some macros like
Code
 Sel: {sel} | Line:{line}
where {sel} and {line} would be replaced by the actual numbers, but here he can not say how many numbers he wants ecc...

Anyway this should not be to hard to implement...
Open for suggestions.

I'd prefer the second option. The first one is to unreadable.

May I have a probably stupid question?

Where the user (will) can write the formatters or the macros?

It could help me with counting characters in a (long) string if it could fit in a char array.

You don't want to do it that way. First get a piece of text and then in the program code determine the size of that string and what to do with it later. If you are using C++ the obvious thing to use is std::string.

@krice: Firstly I decide the length of char array. It depends on display size (16, 20, 40,... characters) for example. Then I create text messages and I would like to know that they are not longer than the array size.
Yes, Arduino is C++ but std::string is usually not used there.

i have posted a patch here: https://sourceforge.net/p/codeblocks/tickets/851/

A long time has not been posted here. I also checked the latest nightly build, but the character counting functionality has not been implemented yet. The ticket status is open also and last updated in 2019.
Will this feature be implemented in the next release, or in a future?
