Unmarshalling csv to a struct
I used jszwec/csvutil in a project recently, easy to use and extend.
mapstructure
- How do I marshal a JSON array into a map?
-
Is there any equivalent to pydantic, serde, etc?
Maybe https://github.com/mitchellh/mapstructure can do what you want? It has some options for Remainder Values and Omit Empty
-
Struggling to get JSON response data into usable struct
I've tried using mapstructure to then marshal the map fields into a struct which mostly works (it struggles with times and custom time types which requires a workaround for each case), but this doesn't feel very idiomatic and requires two passes at marshaling.
-
Return unstructed db rows to struct
Although some orders may have more records maybe a superset can be indentified that you can actually create a struct of it and after gathereing first all values into a map then convert it to a struct maybe using a library like https://github.com/mitchellh/mapstructure . this way you can at least isolate the non structured data only on the data extraction part and the rest of your application can work with well formed structs.

Trying to print JSON data from a file
Alternatively, you could try https://github.com/mitchellh/mapstructure if you don't know what your incoming structure is
-
How to ensure required fields in struct consistently?
I'm doing it by validating a map[string]any first then putting it into a structure using mapstructure. It covers most use-cases and offers the most flexibility, at the expense of a bit of performance.
-
Question about Unmarshalling
That said, it is possible to do this with JSON using something like https://github.com/tidwall/gjson or if you are fine with the switch statement but don't want to marshal and unmarshal again: https://github.com/mitchellh/mapstructure
-
What type of software do you write at your workplace?
https://github.com/mitchellh/mapstructure because we have JSON documents which contain rugged arrays ;-)

Help with mapstructure.Decode()
I've been using mapstructure.Decode to great effect, but currently can't figure out why a given mapping doesn't work. I'd appreciate it if someone could point out wtf I'm doing wrong or at least in the right direction:
-
map[string]interface{} decoder
What do you mean by "decode"? I've used https://github.com/mitchellh/mapstructure but that doesn't quite look like what you're doing.
What are some alternatives?
fwencoder - Fixed width file parser (encoder/decoder) in GO (golang)
jsoniter - A high-performance 100% compatible drop-in replacement of "encoding/json"
go-serializer - :loop: Serialize any custom type or convert any content to []byte or string, for Go Programming Language
viper - Go configuration with fangs
