Very impressed with picocli. Pretty much anything you’d want to do with a CLI. Just tried converting types and sub-subcommands. The docu is top notch, very easy to find things there: http://picocli.info #picocli #java thx @maxandersen for tip

my impressions so far: @picocli is a great choice for cl parsing to start up a tool. #jline is great for interactive input while running. Together they are the best choice I have found so far cli tools on the #jvm. 😀 😎 but now I still need to create my PoC

Congrats. I remember a couple of years ago when I first used it, there were maybe a couple dozen of them. Cudos and thanks for this great framework.

I’m late to the party, but I wholeheartly recommend PicoCLI as well. Our official Neo4j tooling (the admin tool https://github.com/neo4j/neo4j/blob/4.0.3/community/command-line/src/main/java/org/neo4j/cli/AdminTool.java ) uses it and I build the neo4j-migrations cli with it https://github.com/michael-simons/neo4j-migrations/tree/master/neo4j-migrations-cli Remko and the community did an outstanding job here.

Awesome! I did use @picocli some time ago the doc is phenomenal. Nowadays, I usually code these kind of tools using #Clojure and #babashka. You got me interested, so I did the same one with these, 40 lines, execution is instant. No way I use bash again 🤣

(Replying to @picocli * What is it about picocli that makes you happy with it? * What would you do if picocli did not exist?)

Documentation and real world use cases (I.e I found how to inject main conf instance into subcommands and also how to replace key=Val separator with : etc)

Probably would have run my own primitive key=val thing. Would have been enough for the start, but now I have already…

…than planned in a lightweight setup that doesn’t get into my way.

TIL: @picocli CommandLine.execute uses the return code of its command as exit code if the command implements Callable<Integer>. This is also applied to all subcommands. How cool is that!!!

3/ Parsing command line arguments is on its face a simple task but if you want to do it well you do benefit greatly from a library to do it rather than manually munging the String[] you get handed.

There are a bunch of them but my clear winner is @picocli. It just does it all…​

— Max Rydahl Andersen (@maxandersen)
https://twitter.com/maxandersen/status/1290143964234883074
4/ By all I mean that it is annotation based making it declarative and kinda handholds you into a command based class/method structure that is very close to what I would most likely do anyway. It is well documented supports native compilation and has @QuarkusIO extension…​
