When reading configuration from sources with case-sensitive keys,
such as YAML, TOML, and JSON, a user may wish to preserve the case
of keys that appear in maps. For example, consider when the value
of a setting is a map with string keys that are case-sensitive.
Ideally, if the value is not going to be indexed by a Viper lookup
key, then the map value should be treated as an opaque value by
Viper, and its keys should not be modified. See #1014
Viper's default behaviour is that keys are case-sensitive, and this
behavior is implemented by converting all keys to lower-case. For
users that wish to preserve the case of keys, this commit introduces
an Option `CaseSensitiveKeys()` that can be used to configure Viper
to use case-sensitive keys. When CaseSensitiveKeys is enabled, all
keys retain the original case, and lookups become case-sensitive
(except for lookups of values bound to environment variables).
The behavior of Viper could become hard to understand if a user
could change the CaseSensitiveKeys setting after values have been
stored. For this reason, the setting may only be set when creating
a Viper instance, and it cannot be set on the "global" Viper.
- Don't expand user home directory for variable names that simply have a
HOME prefix;
- Support expansion of variables not followed by the path separator.
* 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
* 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
Fixes#71, #93, #158, #168, #209, #141, #160, #162, #190
* Fixed: indentation in comment
* Fixed: Get() returns nil when nested element not found
* Fixed: insensitiviseMaps() made recursive so that nested keys are lowercased
* Fixed: order of expected<=>actual in assert.Equal() statements
* Fixed: find() looks into "overrides" first
* Fixed: TestBindPFlags() to use a new Viper instance
* Fixed: removed extra aliases from display in Debug()
* Added: test for checking precedence of dot-containing keys.
* Fixed: Set() and SetDefault() insert nested values
* Added: tests for overriding nested values
* Changed: AllKeys() includes all keys / AllSettings() includes overridden nested values
* Added: test for shadowed nested key
* Fixed: properties parsing generates nested maps
* Fixed: Get() and IsSet() work correctly on nested values
* Changed: modifier README.md to reflect changes
* Fix typo in description of UnmarshalExact
* Omit 2nd values from range loops
* Delete findCWD method from util (was unused)
* Edit documentation according to golint
* Fix documentation in util
* Use RemoteProvider interface instead of defaultRemoteProvider
* Fix err variable in BindFlagValues
This patch updates the package used for parsing TOML content from
"github.com/BurntSushi/toml" to "github.com/pelletier/go-toml" as the
latter uses a more accepted OSS license (MIT), enabling the inclusion of
Viper or projects that depend on Viper in projects that have licensing
requirements incongruent with the license of the previous TOML package.
Closes#228Closes#225Fixes#179
It breaks Hugo, will have to test/investigate.
Erro when building Hugo docs:
```

```
This reverts commit 7402856f06.
This patch updates the package used for parsing TOML content from
"github.com/BurntSushi/toml" to "github.com/pelletier/go-toml" as the
latter uses a more accepted OSS license (MIT), enabling the inclusion of
Viper or projects that depend on Viper in projects that have licensing
requirements incongruent with the license of the previous TOML package.
This patch replaces the PR https://github.com/spf13/viper/pull/208 after
discussing the matter with @spf13 and deciding to update the TOML parser
instead of making TOML build-optional.
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.
See https://github.com/spf13/hugo/issues/1129
