* win32: use inc_cursor regardless of VT modeAvi Halachmi (:avih)2023-07-231-6/+2
| | | | | | | | | | | | Commit 8ade494 added VT input support and, among others, disabled inc_cursor (in favor of the upstream busybox code) when the terminal has VT input enabled. However, inc_cursor works correctly regardless of the VT mode, and that condition was not required. Revert this condition (but still disable inc_cursor with unicode because it handles wide-glyphs incorrectly).
* win32: add script to create mingw unicode configAvi Halachmi (:avih)2023-07-221-0/+35
| | | | | | Run ./scripts/mk_mingw64u_defconfig to create (or update) configs/mingw64u_defconfig from configs/mingw64_defconfig while enabling UTF8 manifest, UTF8 input, and unicode editing.
* win32: support build with FEATURE_UNICODE_SUPPORTAvi Halachmi (:avih)2023-07-225-1/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FEATURE_UTF8_MANIFEST enables Unicode args and filenames on Win 10+. FEATURE_UTF8_INPUT allows the shell prompt to digest correctly Unicode strings (as UTF8) which are typed or pasted. This commit adds support for building with FEATURE_UNICODE_SUPPORT (mostly by supporting 32 bit wchar_t which busybox expects): - Unicode-aware line-edit - for the most part cursor movement/del being (UTF8) codepoint-aware rather than assuming that one-byte equals one-char-on-screen. - Codepoint-aware operations in some other utils, like rev or wc -c. - When UNICODE_COMBINING_WCHARS and UNICODE_WIDE_WCHARS are enabled, some screen-width-aware operations, like with fold, ls, expand, etc. The busybox Unicode support is incomplete, and even less so with the builtin libc replacement functions, like wcwidth, which are active when UNICODE_USING_LOCALE is unset (mingw lacks those functions). FEATURE_CHECK_UNICODE_IN_ENV should be set so that Unicode is not hardcoded but rather depends on the ANSI codepage and some env vars: LC_ALL=C disables Unicode support, else it's enabled if ACP is UTF8. There's at least one known issue where the tab-completion-prefix-case is not updated correctly, e.g. ~/desk<tab> completes to ~/desktop/ instead of ~/Desktop/, because the code which handles it exists only at the non-unicode code paths, but that's not very critical. That seems to be the only case where mingw-specific code is disabled when Unicode is enabled, but there could be other unknown issues. None of the Unicode options is enabled by default, and the next commit will make it easier to create a build which supports Unicode.
* win32: UTF8 input: improve missing-key-down hackAvi Halachmi (:avih)2023-07-211-11/+47
| | | | | | | | | | | | | | The UTF8 input code works around an issue when pasting at the windows console (but not terminal) that sometimes we get key-up without a prior matching key-down - at which case it generates down. However, previously it detected this by comparing an up-event to the last down-event, which could result in false-positive in cases like: X-down Y-down X-up Y-up (e.g. when typing quickly). Now it remembers the last 8 key-down events when searching a prior matching key-down, which fixes an issue of incorrect repeated keys (in the example above Y-up was incorrectly changed to Y-down).
* win32: avoid crashing the console with poll(2)Ron Yorston2023-07-171-1/+1
| | | | | | | | | | | | | | | Commit 8e6991733 (ash: fix 'read' shell built-in (1)) introduced the use of poll(2) in the shell 'read' built-in. When the UTF8 code page is in use this results in the console crashing if a 3 or more byte UTF8 character is entered. The crash is caused by the use of PeekConsoleInputA() which, like ReadConsoleInputA(), is broken. It can be avoided by using PeekConsoleInputW() instead. The number of key events will differ but this doesn't matter in this case as poll(2) effectively runs in a busy loop with a 1ms sleep.
* date: allow system date to be setRon Yorston2023-07-163-25/+24
| | | | | | | | | Implement clock_settime(2) and enable the '-s' option to allow the system time to be set. This requires elevated privileges. The code in date.c is now identical to upstream BusyBox. Costs 256-272 bytes.

| * hwclock: add get/set parameters optionAndrej Picej2023-07-122-5/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In kernel 5.16 special ioctls were introduced to get/set RTC parameters. Add option to get/set parameters into busybox version of hwclock. Implementation is similar to the one already used in linux-utils hwclock tool. Example of parameter get use: $ hwclock -g 2 The RTC parameter 0x2 is set to 0x2. $ hwclock --param-get bsm The RTC parameter 0x2 is set to 0x2. Example of parameter set use: $ hwclock -p 2=1 The RTC parameter 0x2 will be set to 0x1. $ hwclock -p bsm=2 The RTC parameter 0x2 will be set to 0x2. function old new delta hwclock_main 298 576 +278 .rodata 105231 105400 +169 packed_usage 34541 34576 +35 static.hwclock_longopts 60 84 +24 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 506/0) Total: 506 bytes Signed-off-by: Andrej Picej <andrej.picej@norik.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
