Sebastian Priebe [0] requested Linenoise support for the CLI as an alternative to Readline, so I thought I'd have a go at providing it. Linenoise is a minimal, zero-config, BSD licensed, Readline replacement used in Redis, MongoDB, and Android [1]. 0 - https://lore.kernel.org/netfilter-devel/4df20614cd10434b9f91080d0862dd0c@xxxxxx.group/ 1 - https://github.com/antirez/linenoise/ The upstream repo doesn't contain the infrastructure for building or installing libraries. I've taken a look at how Redis and MongoDB handle this, and they both include the upstream sources in their trees (MongoDB actually uses a C++ fork, Linenoise NG [2]), so I've done the same. 2 - https://github.com/arangodb/linenoise-ng By default, the CLI continues to be build using Readline, but passing `--with-cli=linenoise` instead causes Linenoise to be used instead. `nft -v` has been extended to display what CLI implementation was built and whether mini-gmp was used. Changes since RFC: * two tidy-up patches dropped because they have already been applied; * source now added to include/ and src/; * tests/build/run-tests.sh updated to test `--with-cli=linenoise`; * `nft -v` extended. Jeremy Sowden (3): src, include: add upstream linenoise source. cli: add linenoise CLI implementation. main: add more information to `nft -v`. configure.ac | 14 +- include/Makefile.am | 1 + include/cli.h | 2 +- include/linenoise.h | 73 +++ src/Makefile.am | 12 + src/cli.c | 64 +- src/linenoise.c | 1201 ++++++++++++++++++++++++++++++++++++++ src/main.c | 28 +- tests/build/run-tests.sh | 4 +- 9 files changed, 1381 insertions(+), 18 deletions(-) create mode 100644 include/linenoise.h create mode 100644 src/linenoise.c -- 2.23.0
