[go-nuts] New data convension library

Why not use simplejson
instead? https://godoc.org/github.com/bitly/go-simplejson
Or something similar.

1. I have not seen go-simplejson.

If I knew about go-simplejson then possibly I used go-simplejson.

But I was looking for a set of functions to convert interface{} in certain
types after I unmarshaled to map[string]interface{}

MustString(), MustStringArray() does pretty same thing that my ToString(),
ToStringArray() does.

My functions work with interface{} type and are more general. They could be
used with other serilization formats that are parsed in interface{} like
json package does.

My lib is smaller and simpler. If you look ToString method
https://github.com/CossackPyra/pyraconv/blob/master/util.go#L89

then you will see it is just switch and nil verification.

Actually smaller and simpler would be to use a specific conversion code
when you need it instead of trying to find a package that does it for you.
Or, just use fmt.Sprintf("%s", v)... which pretty much works all the time.

Just a suggestion regarding Go packages - try to avoid writing very general
packages, because
1. It takes time to develop them properly, compared to just using your own
internal function
2. General packages are harder to use than specific ones
3. Specific packages provide much more clarity to the code
4. It's harder to find general packages

i.e. GapBuffer is probably not a good candidate for a package, but
EditorBuffer is.

Basically, only if you really end up using significant amount of same code
in multiple places, then it's worth making into a separate package.

+ Egon

then you will see it is just switch and nil verification.

May be it is reason why it is so unique. Anyway I hope I will see similar
lib to compare.
I have not found many data conversion libraries in go.

After a quick search I found: https://godoc.org/github.com/issue9/conv
But, after looking what it is imported by, it mostly can be just removed.
I.e. only few funcs are actually being used (in public repos) and those
uses can be quite simply replaced with a small utility func.

Nice lib. MustString and MustInt64 are similar to mine and lib supports
more types.

I have functions to work with Array and Map and they dont

e.g. ToStringMap creates map[string]string from map[string]interface{} by
converting it fields using ToString() function.
Same for []string and ToStringArray will convert "string" in ["string"]

json.Unmarshal does not return map[string]string even when all fields are
strings.
