Nepali

This is a golang implementation of the package from opensource-nepal's python package nepali.

We'll try to include all the features provided in the aforementioned package. We'll be releasing features in parts to support all or most features given by go's time package.

Installing

To install this package use go get

$ go get -u github.com/opensource-nepal/go-nepali

Or if there is some error then, use go install

$ go install github.com/opensource-nepal/go-nepali

Usage

NOTE: Currently this package is in beta version, so it only includes basic features like date conversion, formatting and parsing. Also, the output is read-only.

In this package, we provide 2 go packages, nepalitime and dateConverter.

1. nepalitime: The functionalities provided in nepalitime are described below:

   1. To get a NepaliTime object:

      import "github.com/opensource-nepal/go-nepali/nepalitime"
      
      npTime, err := nepalitime.Date(2079,  10,  15,  14,  29,  6,  7)

      The err object could containing error if you pass in errorneous values into the Date function.

      Once you have the NepaliTime object, you will be able to access methods, some of which are described below:

      1. GetEnglishTime() -> Returns the corresponding English time
      2. Date() -> Returns year, month and day as separate return values
      3. Clock() -> Returns hour, minute and second as separate return values

   2. If you already have a time.Time object then, you can get the corresponding NepaliTime object using the function FromEnglishTime:

      import "github.com/opensource-nepal/go-nepali/nepalitime"
      
      // just to ensure that the timezone is Asia/Kathmandu
      // else the time will be adjusted accordingly
      enTime := time.Date(2023, 1, 29, 14, 29, 6, 7, nepalitime.GetNepaliLocation())
      nt, err := nepalitime.FromEnglishTime(enTime)

   3. To parse a date string into a NepaliTime object the Parse function can be used. This is the Nepali equivalent of the time.Parse function of go but instead of using the time parsing format of Mon Jan 2 15:04:05 -0700 MST 2006 we decided to go with the %Y/%m/%d style parsing. We intend on supporting the go style formatting in the upcoming releases. Please see directives section to know which directives we support.

      import "github.com/opensource-nepal/go-nepali/nepalitime"
      
      datetimeStr := "2079/10/14"
      format := "%Y/%m/%d"
      
      npTime, err := nepalitime.Parse(datetimeStr, format)

   4. To get current Nepali time:

      import "github.com/opensource-nepal/go-nepali/nepalitime"
      
      npTime := nepalitime.Now()

   5. To get the current English time in Nepal:

      import "github.com/opensource-nepal/go-nepali/nepalitime"
      
      enTime := nepalitime.GetCurrentEnglishTime()

   6. To format the NepaliTime object to a string that you want.

      import (
        "fmt"
        "github.com/opensource-nepal/go-nepali/nepalitime"
      )
      
      npTime, _ := nepalitime.Date(2079,  10,  15,  14,  29,  6,  7, 123)
      fmt.Println(npTime.Format("%Y/%m/%d %H:%M:%S:%f"))

      Please see directives section to know which directives we support.

2. dateConverter: The functionalities provided in dateConverter are described below:

   1. This is one of the core functionalities in which an English date(not an object) is converted to Nepali date in parts i.e. year, month, day in an array:

      import "github.com/opensource-nepal/go-nepali/dateConverter"
      
      // npDate is an array of 3 length which contains
      // year, month and day sequential form
      npDate, err := dateConverter.EnglishToNepali(2023, 1, 28)

   2. To convert a Nepali date(not an object) to English date in parts i.e. year, month, day in an array:

      import "github.com/opensource-nepal/go-nepali/dateConverter"
      
      // enDate is an array of 3 length which contains
      // year, month and day sequential form
      enDate, err := dateConverter.NepaliToEnglish(2087, 8, 10)
