How to test if a symbol is present?

By the way there is quite some info in the module-description of system.

How to test if a symbol is present?

Thanks both. The proc "declared" seems to do the trick...

How to test if a symbol is present?

I saw the function: defined(nimhasXXX) can you test the existence of any symbol with that? And apparently: defined(nimhasXXXmodule) for modules? I dont see much about it in the manual...what is the syntax? thnx in advance.

Web-application: Where to start?

Previously I made a learning-project json2web (probably not the offical way of doing things but if it works...): But since Jester is low-maintained i have created a sort of migration-project (thanks to guzba, ThomasTJdev and others) which could be of som

Newbie Here! Can I have some feedback on my code?

@khaledh-nim Thnx. Good tip. Looks very clean. Is there a name for that programming-style? I would call it a flag-based decision-tree.. @Hallicon By the way: Kind of funny responses. Maybe of a moody programmer with to much work on his plate...whoa lol!

Create a (or more) nim-management-repo (or something else)

Thanks @zoom I will read your thread aswell (these can be interesting but also read-heavy subjects). I assume it is relevant. As we say in Dutch sometimes I am walking a little behind the facts. To decrease potential bossyness I would like to adjust the term "need" to "want", and assignment ma

Create a (or more) nim-management-repo (or something else)

As the nim-communtiy is maturing, contributors come and go, efforts could be streamlined by coordination and management (in a non-bossy way). I think this is currently missing in nim-community (but i dont see all the nim-stuff). And under this management falls: * needs-list ("demand"). This i

Input/output files from browser using JS backend

You can experiment with some web-programming: The scricon-subproject demonstrates a "thin" javascript approach. But then also you have to get some feel for javascript.

Best location to declare variables in a proc

I still wanted to test if that would even work. I confirm it does. Good to know. >From my perspective: Con: * unneeded handling/cost as compared to declaring outside of loop. * the var can only be used for one pass after which it is reset. Pro: * advantage for refactoring and ease of

The lowest possible module(s) of graphics in Nim?

Thanks. I know I have to more background-reading on the subject. This is a good start!

The lowest possible module(s) of graphics in Nim?

As an extra addition some remarks. A collaborative procedure could be: * find clarity and consensus on process. * find clarity and consensus on situation. * find clarity and consensus on (re)-design. As a proposal, in the development of GUIs one could split the project in parallel phase

The lowest possible module(s) of graphics in Nim?

Thanks all for you responses. It confronts me with the realization that I dont know yet exactly what I want Game-development has (for now) dropped off because of the complexity. One thread is simple math graphics which I can and will probably do with the proposed options..yeah!! Thanx. I a

The lowest possible module(s) of graphics in Nim?

Actually something like NimSvg comes quite close to what I want. Create some graphics on the boundary of math and art...and then you can print them thru Inkscape. Cool! The inventorization is more of a knowledgy interest..(Allthoe I have also an interest in (small) games, but I think that is a

The lowest possible module(s) of graphics in Nim?

Off course you can also do it OS-dependent, but I assume the advantage of layers like SDL is that the OS-specific differences are abstracted away. But then off course you have a non-native (most likely C) layer, but then again I assume the OS-apis are also not written in Nim :-) I assume it dep

The lowest possible module(s) of graphics in Nim?

That is also a nice idea! Render a .svg and read it into Inkscape.. I will look into pixie. Still awaiting the bottom-layer-story...

Using a template as variable-section

> Declare variables where you use them in the smallest possible scope. No > exceptions are known to this rule. Is that not late declaration? When you need a similar var again in another phase give it another name; is that what you mean?

The lowest possible module(s) of graphics in Nim?

I was wondering what is the lowest possible module of graphics in Nim? The minimal you need is some window in which you can draw your stuff. So you actually need some minimal GUI. Can somebody explain how this works? I saw in Mastering Nim (yes I bought the book) the examples and tried some pix

Using a template as variable-section

That is true, didnt think of that. It only works without problems if the vars are not commonly used. So maybe it is not such a good idea. By the way, ideas are not good or bad; the net consequences are benificial or detrimental. But that is diplomacy 2.0. Maybe the word dirty applies after all

Using a template as variable-section

I confirm the dirty-pragma works without injects. Of course the var-template is not a cheap method; in the template variables are declared that the newFunc proc never uses. It is a trade-off: ease of refactoring/coding versus cheap use of resources and depends on the situation and platform if i

Using a template as variable-section

Aha! Cool. Thanks! Hope it doesnt give dirty side-effects :-) I will study the pragma lateron.

Using a template as variable-section

Lately I am interested in refactoring; as I understand it to repartition code into smaller subfunctions, there by increasing oversight, re-usability etc. I want to propose some code using a template for the variable-section. This is useful for refactoring because then you can transplant parts of

Nim version 2.0.8 released

Thanks to all for the new version! And I am happy to see choosenim is being re-addressed. For me it works pretty nicely to update to a new version, revert to older versions and so on. So thanks to the maker dom96 for that and the other beautiful things he has made. It shows the importance of be

@saemideluxe OK thanks for the tips. I would have to do some research in those options. Come to think of it: I must think out the rules anyway and I could test them on a chess/checkers-board with some pieces to see if could come up with something exciting... (Also I have more project-ideas tha

CodeTwig - a small project-viewer

An obvious mistake on my side. getFilePos returns an int64 that i try to put in an int-variable. The error ocurred in old unremoved function but is also present in the new replacement. Apparently ive been blind to this. Wonder why it compiles at my side though. Is the compiler sometimes lenient

@Helmut Thanks for trying out CodeTwig! If you are willing to file an issue on: i am happy to look into the matter. I assume you have successfully compiled other nim-projects on your android-terminal-setup. We can zoom into and discuss the matter

Privilege Escalation with Nim Package Manager - John Hammond

What is the main take-away?

Cheap exceptions, opinionated error handling

I am speaking from a non-technical user-perpective (user but not a developper of Nim) so dont be too harsh on me. When i think about it, the exception raising is an invasive process into the calling program. Future computing maybe should be more polite in terms of respons-request style. (I have

Where the .. does that echo come from?

The following template works for non-release-compilation, but no special flags are needed apparently. You can add a flag-variable wispbo (in my suffix-lingo) or customize the style. Also i dont know if the basename-split-off is cross-platform? Maybe use Path and offical approach instead.. Than

Where the .. does that echo come from?

@clonk That looks promising! I saw it works. A little pruning would be nice like: module_proc_linenr: message But I am gone look into that. Thanks.

Where the .. does that echo come from?

Just for sharing. Sometimes you dont know where an echo cometh from (a bottomless pit maybe :-) ) Below code can help with that. Maybe somebody has a macro that extracts the location-info automatically? Untill now i havent done macros because i am too busy programming.. # logging

CodeTwig - a small project-viewer

I have written a little program called CodeTwig. It may be of interest to Nim-programmers who sometimes loose oversight of their code. :-) CodeTwig is terminal-program to view the outline of the source-code and to show procedures as usage-trees or used-by-trees.

Why not use AI to create momentum in Nim?

Hahaha nice comic-strip. That's how it is.. We might also create a feeling of togetherness in our amazement how bad the AI-answers often are. Maybe I am using an older version but the AI is often very confused :-) It reminds me of my high-school philosophy that any answer is better than no ans

Conversion-to-string-function is hard to find

After some looking into the paths-module, I noticed that you can convert string to Path-type like so: Path(mystring). Backwards you can convert Path-type to string like so: string(myPath). Conversion with $ doesnt work. Apparently $ is just an alias, which implementations walk behind the offical

Wishlist: Ideal UI library for Nim

Well I am happy that there is agreement on the issue and then it can be moved forward. I may have missed pieces of information. Maybe in the future I may contribute but for now I am more invested in Html (definiton-based / non-dsl) ...We keep monitoring the situation as it unfolds ;-)

New to nim... It looks interesting, but can it ... ?

You might better disconnect your decision of using Nim from the specific app-idea that you have and base it on the intrinsic abilities of the language and the copious documentation that exists allready.
