Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
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.

A "Tiny" APISIX Plugin
Reading through the documentation, you will understand why this plugin is called "tiny," i.e., the SDK uses the TinyGo compiler instead of the official Go compiler. You can read more about why this is the case on the SDK\'s overview page, but the TLDR version is that the Go compiler can only produce Wasm binaries that run in the browser.

What's Zig got that C, Rust and Go don't have? [video]
Not only you can fit Go into a kernel, there is at least two products that do so.
TamaGo, used to write the firmware used in USB armory.
https://www.withsecure.com/en/solutions/innovative-security-...
TinyGo, which even has official Arduino and ARM support, and is sponsored by Google
https://tinygo.org/
Ah but that isn't proper Go! Well neither is the C code that is allowed to be used in typical kernel code, almost nothing from ISO C standard library is available, and usually plenty of compiler specific language extensions are used instead.

Show HN: A new stdlib for Golang focusing on platform native support
Reminds me of https://tinygo.org/ - a project that brings Golang to embedded devices, browser (wasm) contexts. Do you converge or diverge from that project?
- TinyGo release 0.29 is out
-
Pico with C
You should also consider TinyGo. It can compile Go for the Pico, and is starting to get good device support.
-
Rust 1.71.0
Thankfully some folks completly ignored whatever the rest of the world thinks system programming is all about and created:
- TinyGo (https://tinygo.org/), which is acknowledged by people in the industry[0][1]
- TamaGo unikernel on USB Armory secure key (https://www.withsecure.com/de/solutions/innovative-security-...)
And then there is the question if writing compilers, assemblers, linkers is systems programming or not.

When would you (not) recommend Go over Rust?
Have you seen TinyGo? In the case of embedded system I would probably still chose C over Rust if the system didn't support dynamic memory allocation, and most embedded systems do not.

>I really hate how for microcontrollers the only two choices are either C++ or Micropython
There's TinyGo as well. https://tinygo.org/

WebAssembly System Interface (WASI) with sockets for Go
Gist link fixed, thanks. Compared to TinyGo, Go with GOOS=wasip1 will probably generate larger artifacts (at least, for now). This is because it bundles the entire Go runtime. The benefit is that it fully supports goroutine scheduling and non-blocking I/O. TinyGo (I believe) still uses a custom asyncify pass and does not support non-blocking I/O nor basic WASI networking (e.g. https://github.com/tinygo-org/tinygo/pull/2748 never landed, but GOOS=wasip1 supports it).
