Previously, this would fail with:
```
panic: reflect.Value.SetMapIndex: value of type string is not assignable to type toml.letter [recovered]
panic: reflect.Value.SetMapIndex: value of type string is not assignable to type toml.letter
```
Now this only panics when the key type cannot be converted from a
string.
* Fixed misspell
* Fixed ineffassign
`user` and `password` always got overwritten
`orderedVals` was initialized with an empty array but always got overwritten by either `sortByLines()` or `sortAlphabetical`
`err` was assigned a `nil` value that was either overwritten or unused anyways
* Fix comment for DeletePath
The comment assumed the method was named Delete, i guess a rename happened at some point
* Update doc_test.go
When a struct is unmarshalled, go-toml now looks at the `default` tag to
provide a default value in case the key is not present in the TOML
document. This is only implemented for string, bool, int, int64,
float64. Additional types can be further implemented on a request-basis.
The name for each field in a struct is used to look up a key in the TOML
tree. A few different (case-sensitive) forms of this name are tried.
Previously, the current, lower-cased, and title-cased versions of the
name are tried. This precludes camelCased keys from mapping back to
fields in structs. This change adds camelCase to the set of keys to
try.
For example, the following TOML:
fooBar = 10
Would previously *not* map to the following struct:
type Foo struct {
FooBar int
}
This change corrects this.
Decoder: allow to customize default field name tag "toml" on decoding.
Example:
```
type doc struct {
title `file:"header"`
}
```
Encoder: allow to customize tags for encoding struct to toml.
Example:
```
type doc struct {
title `file:"header" description:"document title"`
}
```
Fixes#238
The new multiline tag works just like the existing 'commented' tag (i.e.
`multiline:"true"`), and tells go-toml to marshal the value as a
multi-line string. The tag currently has no impact on any non-string
fields.
Patch #185 introduced a backward incompatibility by changing the arguments
of the `Set*` methods on `Tree`.
This change restores the arguments to what they previous were, and
introduces `SetWithComment` and `SetPathWithComment` to perform the same
action.
This fixes two unmarshalling issues:
1. Unmarshalling into a custom integer/float type (e.g. `time.Duration`).
2. Checks for overflows happen before unmarshalling, erroring if an overflow
would happen.
Apart from this it also reduces code duplication a bit.
A new Encoder option emits arrays with more than one line on multiple lines.
This is off by default and toggled with `ArraysWithOneElementPerLine`.
For example:
```
A = [1,2,3]
```
Becomes:
```
A = [
1,
2,
3
]
```
Fixes#200
Usage is similar to the stdlibs JSON encoder/decoder but I tried to
leave the general structure of the code the same.
Main motivation was to support encoding/decoding options to allow
encoding string-type map keys as quoted TOML keys.
This was implemented on the Encoder with QuoteMapKeys(bool).
