Channel is not recognised by VS Code plugin

For that to be recognized you need a .nim.cfg or a .nims file :) E.g. put a as1.nim.cfg file with contents: --threads:on Run and VSCode will correctly highlight everything.

some questions on generating dynamic library

A “const” really only exists at compile time; it’s not something you can export. Try using “let” instead.

Is possible to declare var by using string as identifier

That's not really "using a string" though, that's using a Nim identifier

Intellij ( PhpStorm, PyCharm, RubyMine, Webstorm, Clion ) platform

Well, the most important thing for most editor plugins to add is code completion/go to definition. if IntelliJ IDEA (and other IDEs based on it) support LSP, then you could use nimlsp to add that functionality.

numpy like library for nim

Hi, I wrote a new project which is a ndarray/dataframe library in nim-lang only ([https://github.com/YesDrX/numnim)](https://github.com/YesDrX/numnim\)). If you are familiar with numpy, you know where I'm going. # DEPENDENCIES BLAS LAPACK nimblas nimlapack # IMPORT import ./src/numnim # EXAMP

some questions on generating dynamic library

What I found is that Nim code can (sometimes) be run from other code without calling NimMain, however, it results in random breakage. Any code dealing with constants or other items requiring initialization will break (printing floats for example). So your DLL code may not need NimMain if it's ca

Is possible to declare var by using string as identifier

Here you go, I had to use even more macro magic but it works (for objects at least). I tried to write some descriptive comments to describe what happens but the summary is that we basically unrolls the loop in `createAllVar` at compiletime so we don't have the issues with scopes:

Is possible to declare var by using string as identifier

I think I've got a solution: we write a macro that iterates over the fields of it and creates all the assignments at compiletime. Will be gone for an hour or two though. Just one question, will `it` always be an object?

Is possible to declare var by using string as identifier

I see, the reason you get the undeclared identifier error is because of scopes. When you define a var in a for loop it can't be accessed from outside. This is a simplified example: for i in 0 .. 10: var x = 1 echo x # Error: undeclared identifier: 'x' R

How to ensure that all attributes of an object are explicitly set during creation?

Why is this pragma not the default behaviour? It seems to me that's a better practice to ensure that all fields are initialized by the programmer than relying on the compiler initializing them with a default value. Or at least there could be a compiler define to ensure this default behaviour.

Combining the output of two worker threads on one channel: Is there a more Nim(-mick) way to do it ?

Is possible to declare var by using string as identifier

I think you need to use a macro to convert the string to a identifier. This is something I hacked together that's pretty clean: import macros macro createVar(varName: string, value: untyped): untyped = let newVar = ident(varName.strVal) # create the new identifier fro

Thank you!

You are looking for ordinary `recv`.

is chan.tryRecv() not supposed to wait for the next item te be sent via the channel?

In the code hereunder, if do not put a long enough delay in the loop which calls chan.tryRecv(), the main thread will fail to read from chan and exit, is that the expected behavior of threadpools in Nim? os import threadpool import strformat var chan: Channel[strin

Are json nodes implicitly HasMaps in Nim?

Take a look at the implementation of the JsonNode type here: [https://github.com/nim-lang/Nim/blob/devel/lib/pure/json.nim#L178-L194](https://github.com/nim-lang/Nim/blob/devel/lib/pure/json.nim#L178-L194) As you can see first of all, a JsonNode is a variant object. The JObject kind, which is th

Are json nodes implicitly HasMaps in Nim?

in JavaScript Json nodes are also maps... hashtables (more or less). Is it the same with Nim, i.e. is the lookup for keys in a Json node linear or O(n) ? let jsonNode = parseJson("""{"key": 3.14}""") doAssert jsonNode.kind == JObject doAssert jsonNode["key"].kind == JFl

I have some question, any hints? Thanks 1\. how to kill the `nimMain` in generated DLL, or in other way, how to do not export `nimMain` in DLL? 2\. Should I call NimMain? I have searched and found that Araq said "You need to also call NimMain at startup, generated by Nim"
