* win32: make support for euro input a separate optionRon Yorston2023-06-224-12/+29
| | | | | | | | | | | | | | | | | Commit 93a63809f (win32: add support for the euro currency symbol) made various changes to enable support for the euro symbol. One of these changes allows the euro to be entered from the console even if the current code page doesn't support it. This is probably of limited use: the symbol can be entered but won't be displayed correctly. Move this capability into a separate configuration option, FEATURE_EURO_INPUT, which is disabled by default. Saves 48-64 bytes in the new default case. (GitHub issue #335)
* pgrep,pkill: remove non-functional optionsRon Yorston2023-06-221-0/+55
| | | | | | | | | | | | | | | | Due to limitations of the process scanning code on Windows some features of pgrep and pkill don't work properly: - display/matching of the full command line (-a/-f) - killing the oldest or newest process (-o/-n) - matching session id (-s) To avoid disappointment or error support for these features has been removed. Saves 408-464 bytes.
* ash: standardise treatment of winxp optionRon Yorston2023-06-211-13/+41
| | | | | | | | | | | | | | | | | | | Although 'winxp' is a shell option it could only be set with '-X' on the command line. Fully implement 'winxp' so it can also be set within the shell by 'set -o winxp' and 'set +o winxp'. '-X' no longer needs to be the first option on the command line. Track which shell variables have been imported from a native Windows environment so only those are affected when 'winxp' is changed. The tracking persists in a subshell but is lost when shell variables are exported to the environment so 'set -/+o winxp' is ineffective in a child shell. Costs 48-52 bytes. (GitHub issue #322)
* ash: code shrinkRon Yorston2023-06-211-28/+20
| | | | | | | | | | - There's no need to set USER, LOGNAME, HOME and SHELL as environment variables: making them shell variables is enough. - Use endofname() to detect invalid characters in variable names and take the copy of the invalid variable before it's modified. Saves 48-64 bytes.
* win32: include UTF-8 manifestRon Yorston2023-06-205-1/+21
| | | | | | | | Include a manifest in the binary to set the process code page to UTF-8. This only has an effect from Windows 10 version 1903. Controlled by the FEATURE_UTF8_MANIFEST config setting, disabled by default.
* win32: more applet look-up tweaksRon Yorston2023-06-191-4/+21
| | | | | | | | | | | | | | | | | | When an applet is overridden by BB_OVERRIDE_APPLETS it should still function in certain cases: busybox applet applet.exe busybox --help applet Arrange for this by adding really_find_applet_by_name() as a static function in libbb/appletlib.c. find_applet_by_name() is implemented using this for external use while really_find_applet_by_name() is used internally in some instances. Adds 32 bytes. (GitHub issue #329)
