Purpose of the project

Keeping things DRY for your projects. Set of most popular and frequently used helper functions making it easier to focus on the logic you want to implement rather than re-inventing the wheel ( and spending precious time going through StackOverflow ).

Available helpers

Class	Function	Description
Errors	CheckForError(err error, msg ...string) (string)	Checks for error and returns pre-formatted message with stack trace
Errors	Trace() string	Returns a formatted stack trace
Maps	FlattenMap(nested map[string]interface{}, opts *FlattenOptions) (m map[string]interface{}, err error)	Flattens provided map using customisation options
Maps	UnflattenMap(flat map[string]interface{}, opts *FlattenOptions) (nested map[string]interface{}, err error)	Unflattens provided map into nested map using customisation options
Slices	ExistsInSlice(slice interface{}, value interface{}) bool	Checks if value exists in slice
Slices	RemoveFromSlice(slice interface{}, value interface{})	Removes value from slice
Slices	RemoveFromSliceByIndex(slice interface{}, index int)	Removes value from slice by index
Slices	UniqueSlice (slice interface{}) (uniqueSlice interface{})	Returns a slice with unique values
Structs	CompareStructsReplacedFields (old interface{}, new interface{}) (changedFields []string)	Compares two structs and returns a slice of changed fields
Checks	IsZero(v interface{}) bool	Checks if value of anything passed is zero / empty / nil
Conversion	StringToBytes(s string) []byte	Converts string to byte without unnecessary allocations
Conversion	BytesToString(b []byte) string	Converts byte to string without unnecessary allocations
Conversion	ConvertReplyType[T any](desiredType T, reply []byte) T	Converts any []byte into desired type

Logging

Additional helper for logger setup is available. I've decided to publish it to DRY my own projects. The logging itself provides nice, clean and fully customizable json formatted logging which then can be ingested without any further modifications straight into your loki, ELK or any other logging mechanism. It can be used as following.

import (
    "github.com/lukaszraczylo/pandati"
)

func main() {
    log = pandati.NewLogger()
    log.Critical("Error binding to queue", map[string]interface{}{"_queue": queueName, "_error": err.Error()})
}

Contributing

If you have any suggestions or want to contribute to the project, please open an issue or create a pull request. Pull requests should contain test cases and documentation describing the added functionality.
