Tabs <--> Spaces (Source) Converter

[Mark Jones]

 Hi All. Here is my first useful application, a simple reformatter for source code tabs/spaces. I don't know about anyone else, but I can't stand manually indenting and converting formats! :lol

Any ideas, suggestions, bug reports etc, are welcome.

Either drop a (small text) file onto TSC or click open and select a file. Input is shown on left, output on right. Text copy is supported but not paste. Experiment with the checkboxes for added effect.

Caveats:
* I haven't figured out how to intercept drag-scrolling yet, but the mousewheel and arrows (and pg up/dn) will scroll both the input and output windows simultanously.

* TSC is not resizable. Maybe I could "port" it over to WinAsm and handle dynamically creating the controls at runtime, but this sounds fairly complex for such a simple app. :)

* There are still a few minor glitches with the spaces to tab conversion, but the output should be very usable. The algorithm rapidly outgrew my ability to debug!  :red

I HATE files with spaces instead of tabs :bdg . Will check out prog anyway/

Hi Mark,
I had a quick play with your program and feel that it looks very promising.  One question, though, how come the right hand window only has one scrollbar.  The left window has both horizontal and vertical, the right hand window is missing the vertical scrollbar.

Hi Thomas, yes this little app will "tab" your "spaced" text files, and vice-versa. :)

Hi Paul, glad you like it. I wanted both edit controls to scroll simultaneously in the vertical direction, so they remain in "sync" with each other. It was very annoying keeping things in sync with two vertical scrolbars.   As for the horizontal scrollbars, I left them both because A), if the right scrollbar is removed then it looks really weird, and B), I never found an API that could scroll horizontally. :(

Well, I got news for you, the left window is not synced with the right window on my machine.  XP HE.

They are not synced on windows ME, either.

Hmm.... are you dragging the vertical scrollbar? I haven't found the method of intercepting drag-scrolling either. Yet. But the mousewheel, pgup/pgdown, and up/down keys seem to work in XP SP1 - both edit controls should show the same thing. Does the right one flicker a little?

Here's how the first edit control is setting the scroll position of the second control (did I do something wrong?):

Code Select Expand


Invoke SendDlgItemMessage, hWnd, IDC_TSC_EDIT1, EM_GETFIRSTVISIBLELINE, 0, 0
Mov yScrollPos, Eax
; set same scroll position of Edit2:
Invoke SetDlgItemText, hWnd, IDC_TSC_EDIT2, NULL ; clear edit2
Invoke SetDlgItemText, hWnd, IDC_TSC_EDIT2, hSaveLocalAlloc ; display current text
Invoke SendDlgItemMessage, hWnd, IDC_TSC_EDIT2, EM_LINESCROLL, 0, yScrollPos


Yeah it's not pretty but it was the only thing I could think of at the time. EM_LINESCROLL (by itself) doesn't want to scroll backwards, that is why the control is cleared and reset first...  ::)

Mark,
Yes, the mouse wheel and the pg up/dn work fine.  Just the vertical scrollbar is a problem.  I have seen others make comments about being driven crazy by scrollbars so I feel your pain.  I am glad the mousewheel works as it is my favorite.
