Joe Richey joerichey@google.com 1794792adf Add ability to use custom Flag types 
Users can now use custom flags types (conforming to the Flag interface)
in their applications. They can also use custom flags for the three
global flags (Help, Version, bash completion).

Jesse Szwedko d71794de19 Make ApplyWithError a public method on errorableFlag 
Add to altsrc flags. Otherwise, flagSet() was bypassing altsrc's attempt
at shadowing.

Jesse Szwedko e367fafa3d Return an error when parsing environment variables for values fails 
Currently cli silently (aside from IntSlice and Int64Slice which oddly
printed directly to the error stream) ignores failures that occur when
parsing environment variables for their value for flags that define
environment variables. Instead, we should propogate up the error to the
user.

This is accomplished in a backwards compatible manner by adding a new,
internal, interface which defines an applyWithError function that all
flags here define. In v2, when we can modify the interface, we can drop
this secondary interface and modify `Apply` to return an error.

Jesse Szwedko a00c3f5872 Consider empty environment variables as set 
When assigning values to flags (also when interogatting via
`context.(Global)IsSet`.

For boolean flags, consider empty as `false`.

Using `syscall.Getenv` rather than `os.LookupEnv` in order to support
older Golang versions.

Jake Champlin e0556cf9e8 Add DefaultValue text for flags 
Allows a user to override the default value of a flag in the displayed help output.

Ex:
```
cli.IntFlag{
	Name: "foo, f",
	DefaultText: "random foo",
	Value: "bar",
}
```

Running `(app.name) -h` will now yield:

```
--foo value     (default: "random foo")
```

Fixes: #504

Antoine Eiche 94bc26fd1c Refactoring names from bash to shell 
The refactoring is required since completion is also supported for zsh
shell.

Refactoring details:
- flag generate-bash-completion -> generate-completion
- var  EnableBashCompletion     -> EnableShellCompletion
- var  BashComplete             -> ShellComplete
- var  BashCompletionFlag       -> GenerateCompletionFlag
- type BashCompleteFunc         -> ShellCompleteFunc
 2016-07-26 15:32:03 +02:00
Antoine Eiche 7640bef0eb Add --init-completion flag to print completion code 
This flag takes as input 'bash' or 'zsh' and generates the completion
code for the specified shell.
