JLS discourages use of _ as a variable name in any context about underscore-java HOT 11 CLOSED

For what it's worth, this little naming issue is stopping me from using the library.

Hi,

I prepared a pull request to rename _ with $. :)

from underscore-java.

I'm sorry, I hadn't done my research on whether $ is a safe name to use. From JLS §3.8. Identifiers:

The "Java letters" include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ sign should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems.

Really sorry to suggest another troublesome name. Do you think there's another name you could use?

If both names _ and $ aren't recomended we can leave existing name _, :-)

from underscore-java.

In that case I think $ is the lesser of the 2 evils. $ can still be used for "legacy systems", but _ might become a reserved keyword soon, which is much worse. What do you think? :)

I'm wondering, is there a way to let users of the library configure what name to use? I'm not a Java expert so I don't know how to do it, but maybe you do.

OK. $ is more safe than _. Let's use $. In java we may use classifier attribute for versions of the modules.

It may be one more version with underscore if needed,

Implemented with pull requests #8 and #9.

Great, thanks for resolving this! How do I use the classifier attribute?

Also, thanks for creating this project, the open-source community appreciates it! :)

Classifier attribute is not supported for now, but may be added later to support library with _ class name.

$ was renamed to Underscore and U.
