kconfig/[mn]conf: handle backspace (^H) key

2019-03-29T13:48:01+00:00

Backspace is not working on some terminal emulators which do not send the
key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127).
But currently only '^?' is handled. Let's also handle '^H' for those
terminals.

kconfig: convert to SPDX License Identifier

2018-12-28T13:22:28+00:00

All files in lxdialog/ are licensed under GPL-2.0+, and the rest are
under GPL-2.0. I added GPL-2.0 tags to test scripts in tests/.

Documentation/process/license-rules.rst does not suggest anything
about the flex/bison files. Because flex does not accept the C++
comment style at the very top of a file, I used the C style for
zconf.l, and so for zconf.y for consistency.

kconfig: add xrealloc() helper

We already have xmalloc(), xcalloc().  Add xrealloc() as well
to save tedious error handling.

kconfig/nconf: Fix hang when editing symbol with a long prompt

2016-12-11T11:26:42+00:00

Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters.  dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid.  It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.

The additions in the offset calculations also don't match the intended
size of the window.

Limit the window size and calculate the offset similarly to
show_scroll_win().

nconf: use function calls instead of ncurses' variables LINES and COLS

2013-06-18T21:58:58+00:00

According to the documentation [1], LINES and COLS are initialized by
initscr(); it does not say anything about the behavior when windows are
resized.

Do not rely on the current implementation of ncurses that updates
these variables on resize, but use the propper function calls or macros
to get window dimensions.

The use of the variables in main() was OK, but for the sake of
consistency it was modified to use the macro getmaxyx().

scripts/kconfig/nconf: fix editing long strings

2011-09-09T12:40:08+00:00

The original dialog_inputbox doesn't work with longer than prompt_width
strings, here fixed it in this way:
1) add variable cursor_form_win to record cursor of form_win,
   keep its value always between [0, prompt_width-1];
   reuse the original cursor_position as cursor of the string result,
   use (cursor_position-cursor_form_win) as begin offset to show part of
   the string in form_win;
