goutils

Utility Code for Golang, for better map, slice manipulation and condition handling

Require Go 1.13 or newer

jsonutil

• JSONTime a common time format, fully compatible with JSON and GORM

• Traverse recursively traverse json object and generate path

• TraverseBytes is like Traverse but more efficient if use bytes

sqlutil

• GetMysqlErrCode get mysql error code, if error is nil or not a mysql error, return 0. compatible with GORM

maps

• JSON Map: marshal JSON-format string(s) to map(s) in one function

• Merge: merge maps together

• Sequence: extract map keys in-order, with corresponding values

Support int32, int64, uint32, uint64, string key maps

slice

• Apply: apply a function to a slice (like lambda function in other language)

• Contain: check if a slice contains given element(s)

• Index: find indexes of given element(s) in a slice

• Merge: merge slices together (with unique merge option)

• Reverse: reverse a slice in-place

• Sort: stable (reverse) sort slices, by length or numerical sequence

• Unique: convert a slice to a unique slice (i.e. elements are unique)

Support int32, int64, uint32, uint64, string, bytes slices

condition

• Any, All: judge multiple boolean conditions in one function

• Ternary: ternary expression

• Quaternary: quaternary expression

• HasZeroValue: check if any value is the zero value of its type (e.g. nil, numeric zero)

• HasNumber, HasLetter: check if a string contains number/letter
