* win32: add support for virtual terminal inputRon Yorston2023-03-051-9/+18
| | | | | | | | | | | | | | | | Alter certain applets to support virtual terminal input, if enabled. In many places this is achieved by building previously excluded upstream terminal-handling code. The busybox-w32 implementation of termios(3) functions does nothing if virtual terminal input is disabled, so it can be invoked regardless. Some applet-specific terminal-handling code is also required. This affects less, more, vi and command line editing in the shell. (The `more` applet isn't enabled in the default configuration.) This series of patches adds about 1.7KB to the binaries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1ecb996 attempted to make read_lines() use the last column of the terminal (as re_wrap() did). There were two problems with this: - The size of the buffer allocated for lines wasn't increased to allow for the extra character. - The test for width overflow was moved after the point where the next character was added to the buffer. This caused a buffer overflow in certain circumstances. For example, if the line beyond the end of the display was wider than the display read_lines() would initially read the partial line into a buffer. When the user moved down read_lines() would be called again to ensure the rest of the line was read. This would place the next character in the partial line before checking for overflow. This can be fixed by moving the test for overflow back to where it was before commit 1ecb996 and changing the comparison to `>` rather than `>=`. There are two other places where buffers are created without allowing for width+1 characters. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | winansi: revert to previous console behaviour for vi/lessRon Yorston2016-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Recent changes to make the Windows console behave more like a *nix terminal didn't work too well for vi/less. On *nix the terminal buffer can't be scrolled while such screen-based applications are running. In the Windows console this remained possible and led to confusion. Add a new routine to allow vi/less to revert to their previous behaviour where the cursor is positioned at the top of the buffer and the entire buffer is cleared.
