Hi,

I use AbstractMain . I use this example

I want to know how to localize the helping text, in my case:

g$ fan xtz.fan 

Usage:
   xtz [options] <action>
 Arguments:
   action    add|list
 Options:
   -help, -?    Print usage help

 [19:54:30 12-Mar-12] [err] [xtz] Missing arguments

And how to change the error message for only "Error: Missing args"?

Thanks in advance, Xan

AbstractMain doesn't have any localization support today. As a general principle, nothing designed for "programmers" like APIs, docs, or command line tools are designed for localization in Fantom. Although everything designed for end-users like fwt::Command, etc are designed for localization.

A very very pain for me!. AbstractMain usage message is for users, at least in my case, because I will have users in catalan language with no knowledge of english.

1) Can I modify fantom internal code for achieve that?

2) Can you include it for next releases?

Thanks a lot,

That should be a pretty easy one to fix. Grab the source of AbstractMain, change the uses of strings, to use a localized version:

msg := "$<missingArguments=Missing arguments>"

and define the value for your keys ( missingArguments=donde esta wtf ) in a locale/xx-XX.props file.

The Localization covers... it's about as simple as it could be, I guess.

Can I modify fantom internal code for achieve that?

I think the simplest thing is to just copy the code for AbstractMain or subclass and make your changes.

How can I make these changes in subclass of AbstractMain? Can you say the steps I have to follow?

Thanks,

Depending on how much you want to customize things you might just subclass AbstractMain and override usage to print usage using localized strings. If you really want to localize all the errors and whatnot, then I'd suggest just copying the entire source file and changing it to suite your purposes.

Mmm.. okay. I think override usage is my solution.

Thanks,
