Editor WIP
#1
Here is my Editor project kind of stalled out for awhile. It is 820 LOC and has allot of standard features QB64 has including Cut, Copy and Paste. This is working condition before I attempted to add horizontal scrolling so that part is not working like QB64 yet. You have 100 chars wide plus?... screening.

You should have entire menu with one right click but F2 button not added yet. It pastes the entire file you are working on into the Clipboard to paste where-ever you want. So this thing should not need instructions to use, if it does I'd like to know. The menu lists the shortcut buttons with it's function.

Code: (Select All)

You should have entire menu with one right click but F2 button not added yet. It pastes the entire file you are working on into the Clipboard to paste where-ever you want.

Although not complete, it is a good step further than other efforts and might give an aspiring editor builder some helpful ideas.

This is the commenting I was referring to - even if I don't understand all of it, I can see what each function does, and why it was used! Good job.  Big Grin

Oh thankyou Phil,

for this project I kept a Project Notes Journal it might have been useful day to day but 6 years later, not so much. Except F2, I forgot I had used Ctrl + A for Save As because I used F2 to not only select All, the whole file, but to also load it into the clipboard, I think it saves a step unless you wanted to delete everything!?!

Update: OMG 6 years later?!?! I am thinking of Battleship Mod 842 the code I was hoping to get Phil interested in helping me comment because that is the one I've forgotten and my clues I left behind 6 years ago ain't helping me when I port stuff to JB to show off my game AI Smile

This code is a little better than 6 months old! I agree with Phil the documentation on this one is first rate for me specially the crucial variables shared throughout the program.

As Terry says, it takes real discipline to practice this type of commenting. And patience I would add because this is time consuming to read over and over the code and get wording right in attempts to be meaningful in future like you are reading it for the first time.

The first two screenshots seem like they are from a console, this is a very cool looking and working program.

Quote:Its nearly VS Code now

OK +1 just for the compliment ;-)) but I am sure some study will justify the point.

Dang I have so many pans in the fire at moment... yeah I am bragging Smile

I really want to study this more before I make any comments but already I see you are saving the file, what was it every half second? wow.

I am looking for File mgt: new, open, save, save as.
edit: cut, copy, paste, find, change...
How about help or menu?

Gotta study your code for a bit thanks AP!

Implementing cut copy paste find replace is hard until I add selection function, so I am not doing that currently. File mgmt is just handled with command$(1)
It's a feature to save the file after half a second. I made this for my personal use, and added this feature for the power cut in my house.

A new massive update:
Implement VS-Code style scroll bar, and improved scrolling with mouse (with just adding a '+' in a single line  Big Grin)
Implemented Ctrl Key Combinations:
Ctrl + C -> Copy Current Line ONLY
Ctrl + L -> Delete Whole Line
Ctrl + M -> Overwrite previous line on current line (current line = previous line)
Ctrl + V -> Paste One Line ONLY
No Undo Functions added, cause that's hard too, like colouring keywords.
It's fast, and looks better now.
Still doesn't highlight keywords though
