Hello!
You won't be able to get the progress of the download easily (unless you hack
on the stdlib a bit). But as for downloading without blocking your GUI you've
got two options I think:
* Run `httpclient.downloadFile` (or `get`) in a different thread.
* Use the `AsyncHttpServer` and poll
There's
[FileStream](http://forum.nim-lang.org///nim-lang.org/docs/streams.html#newFileStream,string,FileMode)
that can be used to read chunks of a file using
[readData](http://forum.nim-lang.org///nim-lang.org/docs/streams.html#readData,Stream,Stream,pointer,int),
for example
Thanks for reply. I want to use bit complicated stats. I want to include all
types of columns not just floats.
Anyway, I have further question. I was thinking that I will create a type and
then I will use the Seq[type] to store the data. It is working fine. But I have
another question. How can
HI,
I have ram around 8Gb and I want to read a file which is 16gb what is best way.
I know I cant keep whole data in seq[] is there any alternate? Or it is better
to read the data from file directly rather than reading it in seq and process.
Also, is there a way such that I can keep 10% data
Maybe using
[memfiles](http://forum.nim-lang.org///nim-lang.org/docs/memfiles.html) is a
solution for your problem.
Maybe godot should use nim intead gdscript, Like nim!
Godot is a good game engine.
Use odbc bind mssql database, Run db_odbc.nim's example.
var theDb = open("localhost", "nim", "nim", "test")
for x in theDb.fastRows(sql"select * from qqq"):
echo x
#qqq table
name | id |
你好 xxx
IIRC, fastRows should not be interupted (no good if you want to break the loop).
The snippet you show doesn't give the full picture of how you are using the
iterator.
Can you show more example code?
Gc is giving back memory to the OS if there is 1 MB unused. When I increased
that to 8 MB (I don't remember the exact location, maybe allocate.nim, or
something like that), it helped a lot in these kind of benchmarks.
My apologies. I only looked at seq and (mistakenly) assumed all were faster. On
my (rather slow) laptop, the results of the ptr benchmark are
refc:
Sequence 2.70ms/iter
List 2.99ms/iter
FastStack 2.23ms/iter
Boehm:
Sequence 2.43ms/iter
List

With the Boehm GC **all three** are **slower** than with the default GC. Don't
see a point of Boehm in such case.

PHP is all but a functional programming language. I think you are confusing
terms here, _functional_ programming languages are things like Haskell, Scheme
The problem is that EventArgs is not defined as a ref object, it expects the
struct itself not a pointer, so you have to

Took me 10 second to read and understand your code. I just never liked JS
design for front end programming. Too much overuse of closures, bad error
responses, inconsistencies in

I would vote against sub-forums for different languages and rather suggest to

I checked the documentation, i understand i think, that a natural is a range of

Don't mind.
With the Boehm GC, seq is faster in both of your benchmarks. The default
ref-counting GC definitely has limitations. Also, it's probably better to
initialise FastStack to the same capacity as the seq. 1000 vs 0 isn't really
fair.
Hey, that's cool! Has anybody started a binding for godot yet? Does someone
want to start a git repo, maybe an official one? This guy:
[https://github.com/ggVGc/nim-godot](https://github.com/ggVGc/nim-godot) seems
to have started, but it was a year ago, before this whole push for these new
[https://github.com/Vladar4/FastStack](https://github.com/Vladar4/FastStack)
FastStack is dynamically resizable data structure optimized for fast iteration
over the large arrays of similar elements avoiding memory fragmentation (e.g.,
update and rendering cycles of a game scene).
