Description
Much like how we allow users to use hyphens - in place of underscores, this Issue is to allow users to use all-lowercase versions of identifiers.
Typical case
import fire
class CaseExample(object):
def Alpha():
return 'path 1'
fire.Fire(CaseExample)
$ python example.py Alpha # This is the current behavior.
path 1
$ python example.py alpha # This is the new behavior I want to add.
path 1
$ python example.py ALPHA # Do we want to support other capitalizations? Or just the all lower-case version?
path 1
Corner cases
Unlike with the -/_ support, there can potentially be members with multiple capitalization variants of the name.
E.g.
import fire
class CaseExample(object):
def alpha():
return 'path 1'
def Alpha():
return 'path 2'
fire.Fire(CaseExample)
If the user provides an exact match, it's clear what we should do. I'm open to discussion about how to handle the ambiguous case.
$ python example.py alpha
path 1
$ python example.py Alpha
path 2
$ python example.py ALPHA
WARNING: Ambiguous member access `ALPHA`; accessing `alpha`.
path 1
Why?
The primary motivation is that command line tools typically use lower case commands, whereas Python classes (and occasionally methods/functions) typically have capital names. By allowing these capital names to be used via their lower-case variant, the CLIs that result from normal python code will feel natural more often.
Possible extension
If we also support dropping/adding -/_s in some situations, then people could use snake-case to refer to CamelCase items... just brainstorming. Thoughts?
