I miss Inquirer like library to take user inputs. Except that, Spring Shell with GraalVM works fine. github.com/SBoudrias/In...

Didn’t know about Inquirer, I’ll check it out! Spring Shell provides Flow Components to build interactive CLIs. I wonder if that’s similar to what Inquirer provides? docs.spring.io/spring-shell...

For ttcli (github.com/wimdeblauwe/...), I use Spring Shell and graalvm. Works quite good, although I had to do a workaround for github.com/oracle/graal... for the native compilation.

I use Spring Shell and GraalVM also!

Thanks for sharing! My main challenge has been integration testing, especially for CLIs that perform operations on the file system, downloading/modifying files and so on. I haven’t found a good way yet to achieve that, combined with the power of Testcontainers.

Spring boot. Because it was easy and what I already now. No real challenges, resulting jar file is huge tho 😂

Nice! Do you mean using something like a CommandLineRunner in Spring Boot or using the Spring Shell project?

Bootique is a CLI-oriented Java app engine. So not just a CLI parser, but its core architecture is linked with CLI flags bootique.io/docs/3.x/boo...

Nice, I’ll check it out!

👍 cool. Feel free to ping me if you have any questions

Picocli is pretty nice. picocli.info

jcommander.org is also quite a good alternative to JCommander

That’s a good tool! I used it on a few projects

picocli is good, Spring Shell is also very neat. both work with @graalvm.org 😎

Usually I use all quarkus package that comes with cli solution (if I’m not wrong based on picocli). My biggest challenge is trying not to solve all problems of the world in one cli application

Picocli. Just works.

Just adding up Picocli + @micronautfw.bsky.social (+ optionally @graalvm.org ). So far I only tried with our Pierrot app agorapulse.github.io/pierrot/

Nice! Here are a couple of tools using it, with a broad range of features used. github.com/michael-simo... github.com/michael-simo... github.com/michael-simo... Also nice with JBang github.com/michael-simo... Btw is Remko Popma here as well?

For kcctl 🧸 (github.com/kcctl/kcctl), we are using picocli, compiled into native binaries via @quarkus.io and @graalvm.org. A bit of a learning curve ("pico" is a bit of a misnomer), but once you got the hang, it's really good. Fast enough to launch it even for tab completions, doing a REST call!

That's a very interesting project, thanks for sharing!

Thanks! As you asked for challenges, setting up the build for all the platforms was one. Until recently, GitHub Actions didn't support Apple Silicon runners, so you couldn't build native binaries for Arm Macs. But it is supported by now.
