907c19d40d Support customising mapstructure.DecoderConfig for Unmarshal
* Added a new `DecoderConfigOption` type allowing the user to write custom
  functions that can override the default mapstructure.DecoderConfig
  settings

* Added a new `DecodeHook` function which returns
  a `DecoderConfigOption`. This allows the user to easily set their own
  Decode hooks when Unmarshaling

* Updated Unmarshal, UnmarshalKey and defaultDecoderConfig to support variadic
  trailing `DecoderConfigOption` functions to allow for customisation of
  the default  mapstructure.DecoderConfig

* Added a test case with example usage

e0f7631cf3 WatchConfig and Kubernetes (#284)
Support override of symlink to config file
Include tests for WatchConfig of regular files, as well
as config file which links to a folder which is itself a
link to another folder in the same "watch dir" (the way
Kubernetes exposes config files from ConfigMaps mounted
on a volume in a Pod)

Also:
- Add synchronization with WaitGroup to ensure that the WatchConfig
is properly started before returning
- Remove the watcher when the Config file is removed.

Fixes #284

1a0c4a370c Feature/write config (#287)
* Added method to write into TOML file.

* Added functionality to export configuration based on config type. The feature supports JSON and TOML.

* Added method to write into YAML file.

* Fixed the issue of incorrect defer and error checking order. The error checking must be first otherwise it will cause panic.

* Add WriteConfig methods

* Add support for toml

* Add shared write function and safe methods

* Fix incorrectly modified imports

* Remove extra comments

* Fix spelling

* Make marshal spelling consistent throughout

* Add support for remaining configuration types

This commit moves a significant portion of the code back to viper.go to
facilitate having access to the object when reading the files. The purpose is to
add properties to the viper object at read time, so that we can add the comments
back to the file when writing.

* Add tests for each written file type

* Modify test for updated HCL specification

* Modify to only support HCL write in Go 1.7

* Revert "Modify to only support HCL write in Go 1.7"

This reverts commit 12b34bc4eb92cbf8ebfd56b79519f448607e3e51.

* Need to truncate the file before writing

* Write all settings including overrides

* Use filename variable

* Lint remote.go

* Fix toml return count error

285f151019 Fixed AllKeys() to include env values added with BindEnv()
* Fixed: values bound with BindEnv added to AllKeys()

Cast was not working, and v.env wasn't used when merging keys.

Rewrote explicit and specific casts for maps storing strings or FlagValues.

* Added: test for BindEnv() and AllKeys()

To make sure AllSettings() and Unmarshal() will consider environment
variables added with BindEnv().

50515b700e Increase performance of nested keys search
* Fixed: insensitiviseMaps and tests

All keys (even nested ones) are now lower-cased recursively.

On the way, map[interface{}]interface{} are cast to map[string]interface{}

* Changed: simplified find() fast path and increase performance

Removed searchMapForKey(), fast path directly integrated into searchMap() and
searchMapWithPathPrefixes()
=> more generic (searchMapForKey() wasn't called everywhere it should have)

At the same time, significantly speed up searchMap() and searchMapWithPathPrefixes(),
which are still used for nested keys: the assumption that map keys are all
lower-cased allows to perform
    val = m[key]
instead of
    for k, v := range m {
      if strings.ToLower(k) == strings.ToLower(key) {
        val = v
      }
    }
=> i.e., directly access the map instead of enumerate the keys

5619c0edbe Reset cache on config name change
I stumbled over this when trying to merge multiple configs.

```
viper.SetConfigName("default")
err := viper.MergeInConfig()
```
which caches file path resolvemenet in `v.configFile`

and then
```
viper.SetConfigName("prod")
err := viper.MergeInConfig()
```

which reuses `v.configFile` without updating it accordingly to the new name.

991d18afb2 Adds MergeConfig functionality
This patch adds the `MergeConfig` and `MergeInConfig` functions to
enable reading new configuration files via a merge strategy rather
than replace. For example, take the following as the base YAML for a
configuration:

    hello:
        pop: 37890
        world:
        - us
        - uk
        - fr
        - de

Now imagine we want to read the following, new configuration data:

    hello:
        pop: 45000
        universe:
        - mw
        - ad
    fu: bar

Using the standard `ReadConfig` function the value returned by the
nested key `hello.world` would no longer be present after the second
configuration is read. This is because the `ReadConfig` function and
its relatives replace nested structures entirely.

The new `MergeConfig` function would produce the following config
after the second YAML snippet was merged with the first:

    hello:
        pop: 45000
        world:
        - us
        - uk
        - fr
        - de
        universe:
        - mw
        - ad
    fu: bar

Examples showing how this works can be found in the two unit tests
named `TestMergeConfig` and `TestMergeConfigNoMerge`.

e3bc06f20c Refactored IsSet to examine keys
This patch refactors the IsSet function to examine the keys in order
to see if a key is set instead of simply checking if a value is nil.
This change is necessary due to the fact that default values via
flag bindings will result in the old logic always being true for
the IsSet function due to a type's default value such as 0 for an
integer or an empty string for a string. While a type's default
value may be preferable when getting the value for a key, it
results in a false positive when determining if a key is actually
set. This change enables users to detect whether a key is set by
only returning a flag's value if it has changed.

This reverts commit 8d9577a72e.

The commit is reasonable enough, but this is a major breaking change for Hugo.

We have to figure out how to handle this before we introduce this one.

2b24bea958 fix issue #8
This fixes the aliases in config files bug.  Whenever we register an alias, if there is a value in
the config (or defaults or override) for the alias, we move that value to the new "real key".

Added a test for the bug, which fails without the changes and passes with the changes.

This also fixes a bug in Hugo, where specifying "Taxonomies" in your config file doesn't get recognized,
because Hugo aliases "Taxonomies" to "Indexes" which means that when the code does a Get("Taxnomies") it
got translated to Get("Indexes"), which didn't exist in the original config map.
