Add documentation for YAML args.

[XAMPPRocky]

I can't really find anything about how to do certain commands using YAML.

Example:
subcommands_negate_reqs I tried adding it to the YAML file, and got the following error.

thread '<main>' panicked at 'Unknown Arg setting 'subcommands_negate_reqs' in YAML file for arg 'languages'', /Users/aaron/.multirust/toolchains/stable/cargo/registry/src/git.luolix.top-0a35038f75765ae4/clap-1.4.0/src/args/arg.rs:227

@Aaronepower Did you try subcommandsNegateReqs? For now, you can use examples/17_yaml.rs and examples/17_yaml.yml as reference.

[XAMPPRocky]

No, but why would it be camelCase? Every other command like takes_value is snake_case?

@Aaronepower Or, SubcommandsNegateReqs. It is case insensitive. I am not sure about the exact decision.

SubcommandsNegateReqs is an AppSetting, not Arg setting, so you cannot set this for individual arguments. I've briefly looked at your yaml file. I think this is not what you want because flags are not subcommands. You probably want conflicts_with, or in yaml:

conflicts_with:
  - input

@Aaronepower It's camel case as part of the settings only because it's a bi-product of how AppSettings works, so actually case-insensitive should work too (just not snake case).

See here for an example.

EDIT: Also you can see the 17_yaml.rs and 17_yaml.yml for some other examples.

@kbknapp documentation has not been updated for ~2 weeks. I couldn't find the from_yaml function....

[Vinatorul]

@sru it is updating with every Travis run on master
from_yaml does not present because docs are compiling without --features flag

UPD: I'll fix it in seconds

[WildCryptoFox]

@sru don't forget grep is you friend. 😉

[Vinatorul]

@james-darkfox only on master branch

[WildCryptoFox]

@Vinatorul I just noticed you said "run on master" and just edited away that section of my comment. Thanks for confirming. :-)

I think #276 closes this issue. All yaml docs are on gh-pages
