NestedVM & Nim to make android apps?

First of all, you can make Android apps with Nim using the traditional NDK APIs and amazing libraries like and . Secondly, that project seems to be dead (not active for over 9 years), which is not that good :P

NestedVM & Nim to make android apps?

/ So if you can use gcc to interpret C to Java bytecode, could we use Nim to make android apps (with this method)? I actually don't know if android uses a JVM. I'm not quite sure.

I believe Jester has been added for json.

Nimscript produces slower executable

Thanks! I'll open a GitHub issue using your example. The issue with the workaround will be that on Windows it sometimes doesn't work in combination with Clang if I remember correctly (I don't have access to a Windows machine currently). It will work for now, though.

This is a good question, but the answer for such small deltas may not be related to "less work" as much as compiler/CPU variations. Unless you can really identify the extra work and why it happens/why it cannot be elided, I would not conclude much from 1.2x. Part of answering such questions shou

Nimscript produces slower executable

you are correct about that. `dang.nim` var s = [0,1,2,3] echo s[4] Run `config.nims` task default,"default compile": --define:danger --hints:off --define:lto --genScript:on setCommand "c" task manual,"manual comp

Why do you think there is a 20% improvement? How does the look of nim code compare to rust and python code?

Nimscript produces slower executable

This doesn't seem to be the reason. If I replace `--define:danger` with `--define:release` in the nimscript it becomes significantly slower. (The compiler also says `Hint: gc: arc; threads: on; opt: speed; options: -d:danger` when I have the danger flag.)

Nimscript produces slower executable

`d: danger` and `d: release` have no effect in a `nim.cfg` or a `nims` because they take effect when the global `nim.cfg` gets read. cf

Normalley I compile my program with nim c -d:danger --panics:on --gc:arc -d:useMalloc -d:lto --passL:"-static" --cc:clang --threads:on --run Nalwald.nim Run Now I tried to write a nimscript for the build process: task default, "default compile":

techempower entry for nim stdlib http server

i had actually added prologue one in the past but stopped with just json & plaintext due to lack of time and as xflywind (prologue creator) was still optimizing the framework code. But yeah, it would be great if we add all the tests for the other nim frameworks. Its easy enough.

Great idea! When we're at it, we should also add Jester and Prologue.

Hey folks I just added the nim stdlib http server implementation into the techempower benchmark. the next test onwards it should get included into the main benchmark. as I am not a nim expert, my impleme

What is the difference between `quote do:` and just `quote:`?

The `do` here binds the body to the `quote` whereas otherwise it's bound to the `add` operation which is clearly not what we want.

What is the difference between `quote do:` and just `quote:`?

This works: import macros macro m(x: untyped) = result = newStmtList() result.add quote do: echo `x` m: "hi" Run And this doesn't: import macros macro m(x: untyped) = result = newStmtList() r

What is the difference between `quote do:` and just `quote:`?

I posed this question as an aside in [this thread](https://forum.nim-lang.org/t/8259) and nobody answered; @dom96 was also wondering. Why do macros often use the construct `quote do:`, when `quote:` alone seems to work just fine?

Why can't I use my macro like this?

I've thought of a better solution that allows you to access the procs outside of the loop. import macros macro staticFor(i : untyped, startI, endI : static[int], body : untyped) : untyped = result = newStmtList() let t = genSym(nskTemplate,"t") result.

Guidance on Isolating Memory Leak

Thanks! I had misinterpreted that system modules were auto-imported in nim. The change does fix the memory leak when using the default refc gc. For --gc:{orc|arc}, the app still leaks memory at a far faster rate than originally with --gc:refc.

Guidance on Isolating Memory Leak

The decimal maintainers surmise the leak is from not freeing the cstring returned by the underlying mpd_decimal library function mpd_to_sci(). This seems to be in the following code snippet: proc `$`*(s: DecimalType): string = ## Convert DecimalType to string result = $
