Hello,
I added a Ctrl key to iOS version, and tried to modify the code for iOS to add
the touch for shift-tab, (I use shift-Ctrl-I touches combination). For sending
the touches to vim it is used the add_to_input_buf function, in insertText
function, the code source example is in file link:
https://github.com/applidium/Vim/blob/master/src/gui_ios.m
.....
- (void)insertText:(NSString *)text {
add_to_input_buf((char_u *)[text UTF8String], [text
lengthOfBytesUsingEncoding:NSUTF8StringEncoding]);
[_textView setNeedsDisplay];
}
- (void)deleteBackward {
char escapeString[] = {BS, 0};
[self insertText:[NSString stringWithUTF8String:escapeString]];
}
.....
But I did not find the correct codes (bytes) or the good array of chars, i think (3
bytes) to send to the buffer with add_to_input_buf for shift-tab to send to the
buffer with add_to_input_buf in ex (:) mode, for completion, for example for the
keystrokes :no<sh-tab> to have :normal.
In can say that the <Tab> key (on IOS with Ctrl-I) work well for completion.
Could someone give a little help?
Thanks a lot !
AFAIK, the "cooked" keyboard input mode used by Vim makes all three of
Tab, Ctrl-i and Ctrl-Shift-i appear the same to it (0x09). Blame the
inventors of the ASCII papertape code, who intentionally made the Shift
key status irrelevant when used in combination with Ctrl+letter. So I
don't think you'll be able to map Ctrl-i and Ctrl-Shift-i to do
different things in Vim. Note, BTW, that while I is Shift-i (A is
Shift-a, B is Shift-b, etc.), the notation Ctrl-I is how one usually
shows the Ctrl-i combination (similarly Ctrl-A actually means Ctrl-a,
Ctrl-B means Ctrl-b, etc.).
