Subject [jira] [Commented] (CLI-298) Define CLI options via configuration file
Date Thu, 17 Oct 2019 14:04:00 GMT

    [ https://issues.apache.org/jira/browse/CLI-298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16953776#comment-16953776

Richard commented on CLI-298:
-----------------------------

One other thing: I started this project with the intent of not modifying any of the main code.
However, I am wondering once I've hooked in all the type-conversion formatting and checking
for different types (ints, files etc.) that it might have application to be brought into the
main code WRT configuring and coding CLI options.

> 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.
