Q: A small "TODO" app built using a modular pattern

Olav GundersenI am just beginning to learn JavaScript and although I feel I am starting to grasp the language, I don't feel I know how to structure an app properly.

@Hello Code review type questions are generally considered "off topic" here. SO is generally reserved for helping people diagnose and resolve programming issues they're having. You might have more luck on Code Review, but even there I suspect you'll have to provide more details on what you're trying to improve within your code (performance, readability, ... etc.). Good luck! — nbrooks 29 secs ago
 
12:52 AM
This code would be offtopic on Code Review because the code does not work as advertised. What your code is doing is determining the number of different records, rather than identifying how many are not duplicated. Until the code works as advertised, it is offtopic on Code Review because it's non-working code (and is broken) — Thomas Ward 37 secs ago
@Daniel Is it just me or is that a video without sound? No commentary, just typing? There are so many so much better ones to watch. Btw, you forgot the invocation of the IIFE shown in the video. Regarding the question, just use var q = {} and drop the functions. About the rest of the code, I rather not comment, but if you want you can ask a question at Code Review. — Bergi 28 secs ago
 
wow they picked up on it lol
 
@Bergi - Yes, it is without sound. I adapted the code and added (a working) example to the above question. I read your post on constructor leakage. That was helpful. As for the rest I adapted the code a bit. I am sure I am in for critique and am a thankful receiver. I will have a look at Code Review and take my "beating" .. ;-) .. Thanks for the help here so far. — Daniel 36 secs ago
@Thomas Thanks for clarifying, I'm not very familiar with Code Review's rules. I haven't read this code. The OP stated that they're "not having any problems with it..." but are looking for "ways to improve it". So evidently it's working code (insofar as it meets the OP's needs). If your concern is with the method naming, I would guess that's something bring up in a Code Review...but it's not really a "programming issue", so off-topic here. — nbrooks 10 secs ago

My lesson learned when writing a brand new project that utilises multiple systems together at once
If for nothing else, it enables much better refactoring and lets you see where your design is awkward
 
@DanPantry unless what you just changed is obviously correct but the design was changed so all tests broke

Then you should finish the refactoring and adjust the tests after that

A: ASCII table in Brainfuck

TimtechI think this would be a more efficient way of doing it (at least for the printable ASCII characters): ++++[->++++++++<] Use cell 0 for loop and cell 1 for ASCII codes ++++[->>++++++++<<]>>> Use cell 2 for the space +++>++> ...

More specifically:
The first code block here only results in gibberish, it prints ` ! " # $ % & ' `. The cells your are using don't add up and doesn't make sense. Why use 95 for the loop? And what is the purpose of that loop? Why does cell 1 also contain value 32, same as cell 2? In addition, the "fixed code" that you show is nothing but a minimized version of the code in the original question, with all comments stripped. This answer provides no real value at all in my opinion. — Simon Forsberg ♦ Oct 17 '15 at 10:56

IEnumerable<string> is actually an enumerable of Uris. At what point should I be converting those strings into Uris / reporting them as errors if they don't convert properly?
I'd assume right after parsing them
 
@DanPantry Read -> TryParse -> Process -> Display
 
@EBrown Sounds about right. TY :)
Luckily I have tests to cover the expected case if it breaks! ;-)
 
@DanPantry Because TryParse also checks if input was correct, if not, you re prompt for new input.

@DanPantry I was trying to get Comment to get to work with CommentContainer but haven't managed to get the onChange portion of the Comment component to work correctly... Is this a case where I should pass a callback function to the child Comment component, and call that function onChange?
 
    string GetFixtureFolder()
    {
        // There is really no better way to do this in C#.
        // Do NOT change the location of ./fixtures or this breaks.
        var buildFolder = typeof(NspScannerTests).GetTypeInfo().Assembly.Location;
        var projectFolder = Directory.GetParent(buildFolder).Parent.Parent.Parent.FullName;
        return string.Concat(projectFolder, Path.DirectorySeparatorChar, "fixtures");
    }
forgive me father for I have sinned
@Phrancis looking now, sec
@Phrancis what do you mean by onChange component? There are no inputs here so nothing can change?

hey guys
am I remembering it wrong or was there some code evaluation window in visual studio?
 
@Hakase There's an Immediate window.

@DanPantry TextInputFieldContainer along with TextInputField (which is the one giving me trouble)
 
@Hakase And a C# Interactive Window.
 
ok that's what it's called
 
@Phrancis Yes, here you would pass onChange from TextInputFieldContainer into TextInputField. You do realise that you are not actually rendering TextInputField from the container?
 
@Hakase View -> Other Windows -> C# Interactive
 
4:59 PM
oooh thanks!
 
@DanPantry Right, I patched it up temporarily until I could make it work how I want
I would need to name the callback function prop I pass to the child something other than onChange right?
 
No
onChange is not a special reserved name
I mean, when you're passing it directly to an input, it is
but if you're passing it among other components it's perfectly fine to use that name
 
So something like render() {return <TextInputField onChange={handleChange} />} ? Then use <input onChange={props.handleChange} in the child?
 
errrr
no
<TextInputField onChange={whatever} /> corresponds to props.onChange inside the child
 
Ohhhhh right #NamingThings
 
5:03 PM
so TextInputField = (props) => <input onChange={props.onChange} />
 
OK

@DanPantry is it the case that only if I had more than one callback functions I'm passing (say for instance I have 2 or more input fields in the child) that I would need to find different props names? e.g. <MyChildComponent onNameChange={this.handleNameChange} /> then use <input onChange={props.onNameChange} /> in the child?

Exemple: words(2)=aa,ac,ag,at,ca,cc,,,tt The code is written with Rccp and ...

 
and fields...
and everything but types and constants
 
@Vogel612 Constants in Java are still SHOUTY_SNAKE_CASE, no?
 
yea
that's one of the few exceptions
along with types, Annotations(which are types) and enum members (which are actually just constants)
everything else: camelCase
 
uh, enum members in C# are "actually just constants" - enum members in Java are closer to being full-fledged classes with their own methods and properties and whatnot.
I don't know what Java enum members are, but they're definitely more than "just constants" ;-)
 
5:57 PM
@Mat'sMug In all fairness, you can make C# enum types feel like classes.
 
with what, extension methods?
 
Yeah.
Obviously your options are limited.
 
@Mat'sMug they're constant instances
which works out for reference equality
 
@Vogel612 right. the real problem is the lack of actual value types
 
there is value types
they're called "primitives"
 
5:59 PM
no. there's primitives and then there's everything else
primitives aren't value types the way .net has it
 
well that's semantic hair-splitting ...
 
primitives are hard-wired into the language, they're basically a hack
 
ValueTypes aren't?
 
entire java is a hack
CSI: miami level of hack
 
@Vogel612 Can you define your own value types in Java?
 
6:01 PM
because as I see it the compiler treating objects differently depending on whether they're value types or reference types is basically a hack, too
@EBrown not sure how exactly you mean that, but ... there is no such thing as struct in java
 
^^ that
 
@Vogel612 That's what @Mat'sMug was referring to as far as I can tell.
 
struct ==== value type
 
You cannot define custom value types.
You're stuck with what the language provides.
 
@EBrown why would you need to define custom value types
 
6:02 PM
for plenty of reasons
 
@Vogel612 Point?
Or Vector2?
 
I think you'd find better answers (faster answers more in line with what you want) if you ask this question at Code Review. SO is generally for helping people fix their code that isn't working. If you do have working code, but aren't satisfied with it's performance times, Code Review may be the place for you :) — Tyeler 35 secs ago
 
Both make very good examples of value types.
 
@EBrown that's a complete an utter hack
 
@Vogel612 What?
That makes no sense.
 
6:03 PM
@EBrown what's the point of having this as a value type?
 
no, it's a full-fledged type stored on the stack at runtime
 
in most scenarios
 
@EBrown Vector2 ~== Point
 
@Vogel612 To try to allocate it on the stack instead of the heap.
 
just struct vs class does not determine heap or stack
 
6:04 PM
@Vogel612 I didn't say that...
 
the distinction Heap vs. Stack isn't one you can make in java
 
yes it is
 
I'm so confused.
 
everything but primitives is an object. it goes onto the heap
the heap is subdivided into generations
 
it's actually about assignment semantics

A: What are the differences between value types and reference types in C#?

AaronaughtPlease read: The stack is an implementation detail, and don't ever again repeat the canard that stack allocation is what differentiates value types from reference types in .NET. The CLR may choose to allocate a variable anywhere it wants to. The most important difference is in the assignment se...

local primitives in java are on the stack
 
their reference values are ...
the objects themselves are on the heap

A: Stack and Heap memory in Java

back2dosThe basic difference between stack and heap is the life cycle of the values. Stack values only exist within the scope of the function they are created in. Once it returns, they are discarded. Heap values however exist on the heap. They are created at some point in time, and destructed at another...

> Now Java only stores primitives on the stack. This keeps the stack small and helps keeping individual stack frames small, thus allowing more nested calls.
Objects are created on the heap, and only references (which in turn are primitives) are passed around on the stack.
 
@JeroenVannevel which is exactly what I said ...
because the scope determines where your stuff is allocated.
 
no, a primitive local is not on the heap
 
@JeroenVannevel "everything but primitives [..]"
as I understand from the SO answer linked by Mat's Mug, in C# you don't get to make the choice either
 
6:08 PM
only when they're locals
correct. Though they're working on changing that
 
anyway we all know C# wins. two words: operator override.

eurgh
 
operator overloading is a very double edged sword

@EthanBierlein it's .NET core
I'm starting the process like so
public static Task<IRepository> CloneAsync(Uri url, Uri destination, bool deleteOnDispose)
{
    var proc = new Process
    {
        StartInfo = new ProcessStartInfo("git", $"clone --depth 1 {url.ToString()} {destination.AbsolutePath}"),
        EnableRaisingEvents = true
    };
    var tcs = new TaskCompletionSource<IRepository>();
    proc.Exited += (sender, ev) => {
        // We use AbsolutePath because we know this is a file.
        var repository = new GitRepository(destination, url.ToString(), deleteOnDispose);
 
Ah, nevermind then.
 
I don't care about the output from the process, I just want to pipe it to /dev/null.
Looks like I can just suppress git clone itself
 
@DForck42 If that code is representative of the code in general, you have a secure job for the foreseeable future :) Pop this question over to Code Review instead, and you will get a lot of suggestions which are likely to apply to a lot of the code.

This has a huge map, and there are bugs where they cause pauses. The incremental "mutator assist"--where your code's interrupted to do a small chunk of work, meant to be just microseconds--sometimes wound up scanning the whole map.
