This tool gets the prefix used for word lookup in the dictionary directly from libnickel. It works without any patches or conflicts by using a lot of LD_PRELOAD and dynamic linker hacks.
Japanese (Kanji) is not supported (it uses a different function, and is only called on the Japanese dictionaries anyways).
This was last tested on 4.19.14123, but it should continue to work for the forseeable future.
Theoretically, it should be possible to run this on a non-kobo ARM device (i.e. in QEMU), but this hasn’t been tested. The biggest possible issue with doing this would be the reads to /dev/ntx_io and /sys/class/power_supply/mc13892_bat/status, but it should work fine without those (and it can be patched out if needed).
To build:
You can build dictword-test with NickelTC inside Docker using:
docker run --volume="$PWD:$PWD" --user="$(id --user):$(id --group)" --workdir="$PWD" --env=HOME --entrypoint=make --rm -it ghcr.io/pgaskin/nickeltc:1.0
Or, on the host using:
make CROSS_COMPILE=/path/to/nickeltc/bin/arm-nickel-linux-gnueabihf-
To run (on a Kobo):
chmod +x dictword-test.so && LD_PRELOAD=./dictword-test.so ./dictword-test.so
This can be run over SSH, telnet, or anything else.
