Word (text) processor

[krovit]

Good morning!

I am very pleased to see that the development of QB64 has not stopped. Thank you all for your commitment and perseverance!
I also hope that you are all well because these are very difficult times.

A question: I had found, here on the forums, a procedure for a simple but very efficient and streamlined word processor but now I just can not find it.

Can someone tell me where it is?

Thank you!

[Dimster]

Sorry, I have checked all the programs that I have downloaded but nothing on a Word Processor. I do recall however, like on the other forum, a great discussion on Word Wrap. I didn't capture that discussion either. Sorry.

Thank you for your interest, Dimster.

And  Thank you SMcNeill!
Unfortunately I couldn't get the SUB to work (even adding your KB_GetValue function that I found elsewhere). The simple word-processor I had found (but where the hell will I have put it!!) it was another code, I don't remember who wrote it... But he was certainly one of the usual well-known characters

Sooner or later I find it again and then I post it here, which seems to me something very useful for everyone.

@SMcNeill could you provide a few examples showing off the different `prompt$` options?

This is pretty kick ass idea using a DSL or micro-format for more complex args to `SUB` or `FUNCTION` hadn't occurred to me.

I'd love to see a few examples of this!

Thanks

End Sub





Function KB_GetValue (limiter$, what$)

    jstart = InStr(limiter$, what$): j = 0

    If Mid$(limiter$, InStr(limiter$, what$) + 1, 1) = "-" Then

        GetValue = -1 'unlimited

        Exit Function

    End If



    Do

        j = j + 1

        m$ = Mid$(limiter$, jstart + j, 1)

    Loop Until m$ < "0" Or m$ > "9"

    KB_GetValue = Val(Mid$(limiter$, jstart + 1, j - 1))

End Function

Even without the limiter and prompt, this still gives you several word processing style extensions to the basic INPUT.  For example, arrow keys work, as does the ability to use ALT+ASCII values to directly enter characters via their ascii code (such as ALT-1 for the little smiley face icon dude), as well as the ability to paste code into the input with CTRL-V.

Good morning!

I am very pleased to see that the development of QB64 has not stopped. Thank you all for your commitment and perseverance!
I also hope that you are all well because these are very difficult times.

A question: I had found, here on the forums, a procedure for a simple but very efficient and streamlined word processor but now I just can not find it.

Can someone tell me where it is?

Thank you!

I believe you're thinking of Qxed by StaticX (last two links below).

Here are a bunch of links I found to QB64 word processors and text editors:

+1 Yeah, Pete was really good with editor type work, screen 0 and all!

Plus Dav and Eric have been running Hex editors here at this forum.

Yesss! Thank you, 

that was it! As much as I can - I hope soon - I try to simplify it a little to insert it in my project - if I can do it.

The alternative (but I would like to avoid because I don't like it) could be a free or open source notepad application (launched by the QB64 code) streamlined and simple that presents, at least, the ability to format the text, even in a rudimentary way

I am curious which item you are referring to? Steve's or one of the links?

Steve's is more a very nice Input replacement but might be used as start for editor?
