Gary D. Gregory commented on CLI-298:
-------------------------------------
I am not a fan of the text file format, it is too brittle, not type-safe, and
too easy to mess up.
I see annotations as the way forward here.
External files are good for I18N of course.
Sadly it seems to me that Commons CLI has really fallen behind the times, we
should look for inspiration at JCommander http://jcommander.org/ and picocli
https://picocli.info/
I've am currently using JCommander for new projects but still have some Commons
CLI in older ones.
> Define CLI options via configuration file
> -----------------------------------------
>
> Key: CLI-298
> URL: https://issues.apache.org/jira/browse/CLI-298
> Project: Commons CLI
> Issue Type: Improvement
> Components: Options definition
> Affects Versions: 1.5, Nightly Builds
> Reporter: Richard
> Priority: Minor
> Labels: newbie, pull-request-available, ready-to-commit
> Original Estimate: 336h
> Remaining Estimate: 336h
>
> Create a configuration that enables users to define CLI options via a
> configuration file. Such configuration would normally pre-defined and bundled
> inside the executable jar running the application. This would reduce the
> amount of code required to define command line options and introduce the
> ability to do a lot of the checking a user does (such as converting values to
> integers, files, checking if integers are above/below a certain amount,
> checking that files or directories do/don't exist etc.) For security
> purposes, at compile time calculate an MD5 for the application, if this
> doesn't match at runtime warn of corrupted file exception. Also add I18N
> since this will be driven via the user experience for exception messages.
> So far I've catered for basic options that utilise strings.
> Code already started with a pull request at
> [https://github.com/zendawg/commons-cli] underneath the branch named
> "cli-configuration".
> Apologies in advance, never contributed to Apache SWF before.
