Re: Is Nim better than C?
Nim can do everything that C can do (it is designed as a system programming language, can and has been proven to program a kernel), but will warn you about safety more than any C compiler will ever do. Nim has much more advanced features, so you can do things that are either inelegant, hard or impossible in C. In short, yes it's better and superior than C, as many other languages already do.
Flow Based Programming in Nim
Hi there, I've been reading up on a programming model referred to as Flow-Based
Programming (FBP).
[http://www.jpaulmorrison.com/fbp](http://forum.nim-lang.org///www.jpaulmorrison.com/fbp)/
[https://en.wikipedia.org/wiki/Flow-based_programming](https://en.wikipedia.org/wiki/Flow-based_programming)
I'm wondering if any of you have implemented something like this in Nim?
Central to FBP is the concept that **data** is to be seen as the primary
"thing" in an application, This "thing" moves from one process to another,
undergoing a constant series of transformations.
Processes receive and send packets of information between each other.
The sole purpose of a process is to transform the data it receives into another
form, before sending it off to another process.
A few other highlights:
1. A process has IN and OUT channels (kind of like a socket's receive and
send)
2. Processes are connected together (ex: connect("ProcessA.OUT",
"ProcessB.IN") to create a network of interconnected processes
3. Data (Information Packets) is received by the receiving process(es) in the
order in which they were sent by the sending process
4. Once they have finished transforming the data they have received, a
receiving process sits iddle until new data is sent to it.
I could see model working well for making the jump from process diagrams into
code implementation, almost having a 1:1 relationship. Well, especially in my
line of work as a IT Biz Analyst where we do a lot of process diagrams. Mapping
a process diagram to a process using this approach would seem trivial.
The only thing is I'm not quite sure how to implement this in Nim (well, in any
langauge in general).
The author of "Flow Based Programming", Paul Morrison, pointed me to a couple
of implementations of this approach:
[http://www.jpaulmorrison.com/fbp/jsyntax.htm](http://forum.nim-lang.org///www.jpaulmorrison.com/fbp/jsyntax.htm)
This approach has been implemented in Java, in C++, Javascript. He tells me
implementation of this approach depends on the language being used supporting
threads (which I know Nim does). But I have to admit I'm not strong enough a
programmer to figure it out on my own.
So if anyone is interested, and have a few ideas or pointers, I hope you don't
mind chiming in!
Regards,

Congratulations!
NimYAML 0.7.0 released
Since we have Nim 0.15.0 now, NimYAML 0.7.0 follows. This list is relevant for upgrading from a previous version: * The API has been split over several modules. Importing the [base package](http://forum.nim-lang.org///flyx.github.io/NimYAML/yaml.html) imports all subpackages, so this change is backwards-compatible. However, you are encouraged to import only those parts of the API you need. * It is possible to call all loading procs with a `string` instead of a `Stream` input. Loading YAML directly from a string will enable NimYAML to include correct line content in its parsing exceptions. This is not always possible with using Streams, where it will return an empty string instead if the line content is not available. * The API for writing custom represent/construct procs has changed. [representObject](http://forum.nim-lang.org///flyx.github.io/NimYAML/serialization.html#representobject) does not return a `YamlStreamEvent` iterator anymore. Instead, the implementation shall put its generated event(s) into the `SerializationContext`. You have to update existing code if you use that functionality. Major new features are: * The serialization API features better checks and error messages in case of invalid input. This makes NimYAML feasible for user-written configuration files. * Usage of first-class iterators has been removed to make compiling to JS possible. However, finishing this is still blocked by a Nim compiler bug, see [here](https://github.com/flyx/NimYAML/issues/24). * YAML compliance has been improved. A complete list of changes is available [here](https://github.com/flyx/NimYAML/blob/devel/CHANGELOG.md). NimYAML 0.7.0 requires Nim 0.15.0.
Re: Version 0.15 released!
@Ar Just want to point out that the "box" in every module does a search over all (indexed) modules and therefor not just helpful for big modules.
Re: Is Nim better than C?
**Language X** can be used as a replacement for C language(used as a better C), where **Language X** can be anywhere from C++, Java, D, Python, Go, OCaml, Erlang, Javascript etc., depending on what you are trying to do. Being better than C at _something_ is not that difficult. Today C is chosen mostly because old habits die hard, not because it's the "best language overall".
Is Nim better than C?
In the Nim in Action, it says that Nim can be used as a replacement of C language (used as a better C), but does that mean Nim is better and superior on C?
Re: Version 0.15 released!
Congratulations on the release. The search box is really helpful, for big modules (system for example [http://nim-lang.org/docs/system.html](http://forum.nim-lang.org///nim-lang.org/docs/system.html)) i'd like to have the index following the main content the way crystal does, which makes exploring a module more helpful [https://crystal-lang.org/api/0.19.3](https://crystal-lang.org/api/0.19.3)/
Re: Version 0.15 released!
> the old ways still apply though nimsuggest ... Okay. Thanks Araq.
Re: Version 0.15 released!
> Is the nim e install_tools.nims official recommended way to use nimsuggest > from now? (No more supported nimble install nimsuggest?) `install_tools` is for the `tar.xz` based release. When you build from github, the old ways still apply though nimsuggest in particular has a `compile_without_nimble` script because nimble doesn't work well with packages that depend on the compiler package.
Re: Version 0.15 released!
Very awesome! I will enjoy my continued learning of nimrod
Re: Version 0.15 released!
Congrats new release! I have a little question about the download page. Is the nim e install_tools.nims official recommended way to use nimsuggest from now? (No more supported nimble install nimsuggest?)
Version 0.15 released!
We finally pulled the plug, new release has arrived. See [http://nim-lang.org/news/2016_09_30_version_0_15_0_released.html?ref=forum](http://forum.nim-lang.org///nim-lang.org/news/2016_09_30_version_0_15_0_released.html?ref=forum) for the details.
