Long help strings can now be broken up with newlines that will be
properly aligned in help messages. Simply place a `{n}` wherever you'd
like the newline to appear.
Closes#145
Allows creating help messages with a more unified look, similar to how
docopt and getopts are formatted. (i.e. flags and options are combined
into a single group)
Closes#158
You can now use ArgName::variants() to get a Vec<&'static str> of
vairant names (Nice for Arg::possible_values()). It's not as good as
implementing Iterator for the enum, but that can't be done without being
able to concat AST tokens in order to make an "EnumIter" type which
implements iterator and keeps track of when to yield None. But the
overall intent of this issue was to be able to iterate variant names,
which is now possible.
Closes#119
* assure `make test` works on OSX as well
* simplified entire makefile, by basically removing sed invocations to
manipulate the Cargo.toml file under source control.
* *works for me* predicate
This should probably be tested on another system as well, just to be
sure it makes sense for everyone.
Allows creating an enum with CamelCase to follow Rust guidelines, but
then will match ascii case insensitive. This means variant
SomeEnum::Emacs would match string "emacs".
Closes#104
Breaking Change
Instead of requiring a Vec<&str> for various Arg::*_all() and
Arg::possible_values() methods this
commit now requires a generic IntoIterator<Item=AsRef<str>> which allows
things such as constant arrays. This change requires that any
Arg::*_all() methods be changed from vec!["val", "val"] -> let vals =
["val", "val"]; some_arg.possible_values(&vals) (or vals.iter()).
Closes#87
