evendeep(-go)

Intro to `evendeep`

This is a standard deepcopy library. It provides per-field copying deeply, and compares deeply abilities.

This library is designed for making everything customizable.

Features

loosely and reasonable data-types conversions, acrossing primitives, composites and functions, with customizable converters/transformers

unexported values (optional), ...

circular references immunization

fully customizable

user-defined value/type converters/transformers
user-defined field to field name converting rule via struct Tag

easily apply different strategies

basic strategies are: copy-n-merge, clone,
strategies per struct field: slicecopy, slicemerge, mapcopy, mapmerge, omitempty (keep if source is zero or nil), omitnil, omitzero, keepneq (keep if not equal), cleareq (clear if equal), ...

copy fields by name or ordinal

field to field
field to method, method to field
value to function (as input), function result to value
slice[0] to struct, struct to slice[0]
struct to map, map to struct
User-defined extractor/getter on various source
User-defined setter for struct or map target (if mapkey is string)
...

The deep series

deepcopy: DeepCopy(), or New()
deepclone:MakeClone()
deepequal: DeepEqual()
deepdiff: DeepDiff()

Compatibilities

Run for Go Modules and Generics enable, and log/slog present (go1.21+ since v1)
- since v1, debug/buildinfo requires go1.18+, log/slog wants go1.21+.
- for the v0.x versions, go1.11+ is okay.

History

Roadmap

These features had been planning but still on ice.

Name converting and mapping for cms.ByOrdinal (*) mode: a universal name converter can be applied in copying field to field.

Use SourceExtractor and TargetSetter together (might be impossible)

More builtin converters (might not be a requisite)

Handle circular pointer (DONE)

Issue me if you wanna put it or them on the table.
