* libarchive: pdpmake requires some ar functionsRon Yorston2024-11-061-0/+1
| | | | | | | pdpmake, like make, requires get_header_ar.o and unpack_ar_archive.o from libarchive. This dependency wasn't made explicit in Kbuild.src so building pdpmake failed unless other applets requiring those files were enabled (ar, dpkg, dpkg-deb or make).
* make: new appletRon Yorston2022-08-011-0/+1
| | | | | | | | | This is an experimental implementation of make for busybox-w32, based on my public domain POSIX make: https://frippery.org/make/ (GitHub issue #44)
* hush: allow hush to run embedded scriptsRon Yorston2018-11-271-1/+1
| | | | | | | | | | | | | Embedded scripts require a shell to be present in the BusyBox binary. Allow either ash or hush to be used for this purpose. If both are enabled ash takes precedence. The size of the binary is unchanged in the default configuration: both ash and hush are present but support for embedded scripts isn't compiled into hush.

* ash: allow shell scripts to be embedded in the binaryDenys Vlasenko2018-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | To assist in the deployment of shell scripts it may be convenient to embed them in the BusyBox binary. 'Embed scripts in the binary' takes any files in the directory 'embed', concatenates them with null separators, compresses them and embeds them in the binary. When scripts are embedded in the binary, scripts can be run as 'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism. embed/nologin is provided as an example. function old new delta packed_scripts - 123 +123 unpack_scripts - 87 +87 ash_main 1103 1171 +68 run_applet_and_exit 78 128 +50 get_script_content - 32 +32 script_names - 10 +10 expmeta 663 659 -4 ------------------------------------------------------------------------------ (add/remove: 4/0 grow/shrink: 2/1 up/down: 370/-4) Total: 366 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
