# Tokiko
A simple gopher daemon written in Golang.
A simple gopher daemon written in Golang.\
Forked from [shokara/thomomys](https://gt.kalli.st/shokara/thomomys)
## Credits
I blatantly copied the `parseconfig()` code from [partage](http://z3bra.org/partage/)
Some portions of code have been copied from [z3bra](http://z3bra.org)'s [partage](http://z3bra.org/partage/) project.

Package ini provides INI file read and write functionality in Go.
## Features
- Load from multiple data sources(file, `[]byte`, `io.Reader` and `io.ReadCloser`) with overwrites.
- Read with recursion values.
- Read with parent-child sections.
- Read with auto-increment key names.
- Read with multiple-line values.
- Read with tons of helper methods.
- Read and convert values to Go types.
- Read and **WRITE** comments of sections and keys.
- Manipulate sections, keys and comments with ease.
- Keep sections and keys in order as you parse and save.
## Installation
The minimum requirement of Go is **1.13**.
```sh
$ go get gopkg.in/ini.v1
```
Please add `-u` flag to update in the future.
