Feature #12843

We currently have `File.basename()` File.basename() and `File.dirname()`, File.dirname(), both of which work very well and are quite useful when working with files and directories. When you want to get the filename without extension, you can use something like this: ```ruby File.basename('foo/bar/test.rb', '.rb') File.basename('foo/bar/test.rb', '.*') ``` While this works very well, I was wondering if it would be possible to add a method that does precisely that for you but which requires only one argument - the path. That would allow us to omit the ',' and the second argument, which I think would be nice to have. Resulting ruby code may be a tiny bit shorter: ```ruby File.basename('foo/bar/test.rb', '.*') File.methodXY('foo/bar/test.rb') ``` Where `.methodXY()` .methodXY() should be the name of the new method added. I would thus like to suggest a way for a new method addition, on the class `File` File namespace, just like `.basename()` .basename() and `.dirname()`, .dirname(), that will return the filename of a given path/file, but without any suffix and without any path - so, similar to `File.basename()` File.basename() but to additionally already chop away all extname suffixes. Giving things a proper, meaningful name is often difficult. In particular when method names should ideally be short; both `.dirname` .dirname and `.basename` .basename are quite short too. My obvious choice would be: ```ruby File.filename() ``` But I am not sure if this is a good name. A problem is that I can not come up with a better name. We also already have `File.extname()` File.extname() in order to determine the "extension name" of the file. https://ruby-doc.org/core-2.2.0/File.html#method-c-extname So we essentially have 3 behaviours - obtain the name of the directory via `.dirname`; .dirname; obtain the name of the file/entry itself, via `.basename`; .basename; and being able to obtain the name of the extension via `.extname`. .extname. What we actually appear to be missing is to obtain the part of the name of a path/file/directory WITHOUT the extension and WITHOUT the leading dirname part. If `File.filename()` File.filename() is not a good name then perhaps any of the following may serve as better alternatives; some are obviously not really great names though, I add them mostly for comparison: ```ruby File.no_suffix() File.corename() File.corefile() File.shortname() File.short_name() File.sname() File.filename_without_extension() # Probably too verbose but # probably more descriptive than the other names ``` Anyway, I guess the name of the method is one thing - if the functionality itself would be approved, then I am sure a good name can be found for the functionality anyway if none of the above are very good choices. I just thought that it should fit towards `.dirname` `.basename` .dirname .basename and `.extname`, .extname, hence why I put `.filename` .filename first. Thanks for reading!
