I want to create a text editor in n-curses, but I have a dumb question, would it be possible to dynamically create LaTeX-like formatting?

Like, when you finish typing

\lambda

or

 \frac{\partial u}{\partial t}

, it appears as a single character (as it would normally appear in a compiled TeX document), much like what Word does, but better.

What would some good books/resources be for this project?

No, you're okay at letting an IDE and Virtual Environment fix all your awful mistakes.
You should switch industries entirely.

In a terminal? That means you need the unicode math symbols, and a font that supports it.
https://en.wikipedia.org/wiki/Mathematical_operators_and_symbols_in_Unicode

You have the whole multi-character bracket thing that's supposed to line up (pic related) and such. I'd advise using maybe Python3, and don't bother about the editor first: just write a standalone "TeX to pretty terminal formula" renderer so it's easier to test, and then integrate it with something. Maybe you need some formal grammar training because this is a language to something-that's-almost-a-language converter, so yeah. Your book's title is Wikipedia.

Here's a quick and dirty proof-of-concept sample I hand-assembled with the big parens in https://en.wikipedia.org/wiki/Bracket#Encoding

  ⎛  ⎞
K ⎜E ⎟K 
  ⎝  ⎠

looks like pic related in my terminal. (gnome-terminal with Schumacher Clean) Your results may vary. It seems like on my terminal you have to add a space after the wide characters such as K and ↪ because otherwise they overlap with the following character, but I can't tell if that's normal.

Is Rust a meme ?

>>59917801
>such as K and ↪
K was meant to be a double-stroke K (U+0001D542) in case you had a doubt. Yeah to sum up : read up about parsers and Unicode.

>>59917801
>K ⎜E ⎟K
>>59917841
MAN fuck that shit! 4chan's converting U+0001D542 into a normal K like it even make sense bitch please! anyway, here's the sample in Base64:

ICDijpsgIOKOng0K8J2VgiDijpzwnZS8IOKOn/CdlYINCiAg4o6dICDijqANCg==

Just do the following on Lunix

base64 -d <<END
ICDijpsgIOKOng0K8J2VgiDijpzwnZS8IOKOn/CdlYINCiAg4o6dICDijqANCg==
END

or use google if not applicable. I even put CRLF line terminators just so it works on Wangblows.

Thoughts on Go?

Thanks! This definitely looks like something I can do (eventually anyway... Kind of struggling my way through SICP atm).

I am kind of confused, though. When you say
>TeX to pretty terminal formula
Do you mean I should implement the text into strictly unicode symbols? Because I'm having a hard time wrapping my head on how I would do it to have something like \int^a_b using unicode.

Just found out about this website:
http://rosalind.info/problems/locations/
and am doing some of the problems on there...

Dumb question (and this may just be XCode messing with me)

I have the following code:

#include <iostream>

using namespace std;
void  solve(string& toProcess);

int main(int argc, const char * argv[])
{
    //Sample Dataset:
    string test = "AAAACCCGGT";
    cout << test << endl;
    solve(test);
    return 0;
}

char complement(char input)
{
    switch(input)
    {
        case('A'): return 'T';
        case ('T'): return 'A';
        case ('C'): return 'G';
        case('G'): return 'C';
    }
    return ' ';
}

void  solve(string& toProcess)
{
    string toReverse = "";
    for(char bp : toProcess)
    {
        toReverse += complement(bp);
    }
    cout << toReverse << endl;
    for(int ind = toReverse.length()-1; ind >=0; ind--)
    {
        cout << ind<<endl;
        cout << toReverse[ind] << '-'; //doesn't print unless I include the above statement
    }
}

When I remove the "cout << ind << endl" part of the last for loop, nothing prints, but when I do, it prints both the number and the letter... What the hell?

Just tested this with g++ and it works fine... I think it's just XCode freaking out... What do?

Programming is a terrible profession. For one, you are not respected at any normal company. You're known as 'IT' or 'tech' and everyone gossips about how disgusting everyone is in the department. Every day, some Alpha who probably does nothing at his job except get his secretary to suck his dick in his corner office cucks you into doing random bitch work, and then yells at you when it's not done by the deadline despite it being impossible to complete the work requested. Not only that, the code rarely works, your co-workers are smelly Indians brought in by Tata Consultancy and connive to replace your job at all times for half the salary, and the work never, ever ends. You pollute your body with sugar and toxins, deprive it of sleep, and let it rot while you sit the majority of the day, neglecting any healthy exercise, social interaction or life goal attainment. It's like a Postal worker, but coupled with feelings of patheticness, lonliness, helplessness, rage and total hopelessness.

Women, when they hear you are a programmer, instantly remove you from the potential pool of mates as they know your earning potential is maxed early and your career over at 35. They are also instantly disgusted by you. It is far better to tell a woman you are on welfare than to out yourself as a computer programmer. It's also highly embarrassing for a woman to date or be married to a programmer, as virtually everyone knows they are the grown up version of the hopeless virgin in high school. One who never really grew up and became normal and fit into society, but rather found an environment where he could escape the reality of his situation and be invisible, able to hide the toxic shame and utter humiliation that is the programmer.

After Dentists, programmers have the highest rates of mental disorders, especially depression and suicide.

Programmers, why haven't you taken the cyanide pill?

Yeah, don't waste space, pack it with pragma pack, or keep it as a separate parallel data structure. Hiding the info in the pointer means extra operations to do an index. And unless you don't access the pointer very often, it becomes unneeded overhead.

Rust, CL, or both?

I'm trying to implement the Kosaraju-Sharir algorithm for detecting strongly-connected components in a digraph. Part of this algorithm involves doing a topological sort on a reversed copy of the graph. This is where my issue arises.

I've performed tests with topological sorting on a directed acyclic graph by following a video tutorial. As it's implemented with depth-first search, the order in which vertices are recursively visited is dependent on how they appear within the linked-lists that store this information. The post-reverse order array produced by the instructor's topological sort differed from my own due to this variance, but my array still was validly topologically sorted.

Unfortunately, this isn't holding true for my implementation of the Kosaraju-Sharir algorithm. My topological sort result differs from the instructor's, and this time it matters -- it causes the algorithm to incorrectly identify strongly connected components.

I'm not sure if anything can really be done about this. It all seems dependent on the somewhat arbitrary representation of adjacent vertices within the graph's array of linked-lists, and that's not really something I can directly control.

Any ideas?

Read the error messages again, what are the limits for a double? And are your values those limits? Also, don't presume EVER that long double is capable of storing a value larger than a double. So systems just don't have that, and I'm not sure if libgcc provides such emulation.

Making baby steps into 8x86, using emu8086 to learn the basics atm. Learned to use the int21h=0ah interrupt to read a buffered string.
Yet I can't wrap my head around the following code [as in: why it doesnt work]:

charscan db 0h;
//skipping the stuff that's working
mov cx, bx ; BX holds the address for the buffered string
add cx, 2 ;moving it to the first char of the input
mov charscan, [cx]

By my current understanding of 8x86, the last line should copy the contents of the address stored in CX into the charscan variable.
>BUT I GET THIS ERROR:

wrong parameters: MOV charscan, [cx]
probably no zero prefix for hex; or no 'h' suffix; or wrong addressing; or undefined var: [cx]

Yes, but your values are outside what a double can hold, hence the promotion. Which is what we've been telling you...

Also, as another anon mentioned long double and double can be the same type, not all systems have a floating point type larger than 64 bits, hence the warning.

in c# does it make sense to split up methods in two if you can use input from the 1st to call the 2nd?

what I'm trying to do is

private void btn_Click(){
validate();
}

private void validate(){
for (textbox in panel)
{
validate(textbox)
}
}

private void validate(textbox)
{
blah
}

the actual code is going through a bunch of panels with different amounts of textboxes so its a bit longer. Its easier for me to read though if I split it

but i'm storing it in a long double not double.

>>59924945
You should split functions up based on re-usability and legibility.
If you think you'll use validate(textbox) elsewhere, or it's a particularly long method, then yes.

But if they're both relatively short and one-context use, then you should combine them

>>59924740
One very important thing you need to know about C++ if you plan on switching to it.

Consider the following Python:

class exampleclass:
    # methods and such

def instantiate_exampleclass():
    x = exampleclass()

instantiate_exampleclass()
exit()

What happens to x? It gets created, and then the function returns, and then what happens to it? You can't get to it, so it's as good as gone, right?

This is a principle called garbage collection, implemented in most modern programming languages. If data is as good as gone, an internal language procedure called the garbage collector is invoked to make sure it *actually* becomes gone.

Now here's what you need to know about C++: it doesn't do that.

Consider:

class exampleclass {
    // methods and such
};

void instantiate_exampleclass() {
    exampleclass* x = new exampleclass();
}

int main() {
    instantiate_exampleclass();
    return 0;
}

In this code, the instance of exampleclass to which x is a reference gets trapped in memory forever when that reference is lost. Nothing is running behind the scenes waiting to come along and clean it up. It's become what's called a memory leak. When memory leaks accumulate, they can clog up the RAM segment your program is using, causing your program's performance to quickly degrade.

The usual way around memory leaks is the 'delete' keyword.

'Delete' is the opposite of 'new': if you obtain a reference to a newly created class instance using 'new', you have to at some point purge that instance from your program's memory using 'delete'. But be careful: if you use 'delete' on a reference to an instance while other references to that instance still exist, accessing the instance through those references becomes undefined behavior and might crash your program -- or worse, you might successfully access the instance, but find the integrity of its data damaged, causing the code that handles that data to run off the rails.

I must say
C hash is a brettty comfy programming language.

>>59925051
You don't understand how literals work. Literals have a predefined type. floating-point literals have type double, you need to cast them. Try,

long double MIN = (long double)4.94065645841246544e-324;

Also, as several anons pointed out, java doubles and C doubles have the same limits, use the predefined limits. Also, what you are trying to do is fundamentally flawed. What happens if someone gives a value that is outside even a long double's? There is a second argument to strtod, look into that.

>>59921765
Are minorities posting about "social justice" simply lobbying for their own interests? "My tweets are a mix of golang posts and shilling for myself."

I've tracked the bug. For some reason, it'll work if the reverse post-order array returned by my topological sort is reversed. This bears a bit more investigation, but is definitely fixable.

>>59925159
>What happens if someone gives a value that is outside even a long double's?
I'm only checking if a number fits in a double. nothing more.

if it doesn't fit, i throw an error.

i was only getting warnings compiling with the -Weverything flag, btw.

-Wall doesn't catch it.

>>59923928
Couldn't hurt, wdg is pretty desolate.

>>59923435
nice pasta

>>59925219
Yeah -Weverything marks implicit type promotions as warnings, -Wall doesn't because your sanity is key.

>if it doesn't fit, i throw an error.
How will you know it won't fit? If a value that exceeds the limits of a long double is put into strtold the result is HUGE_VAL and errno is set to ERANGE which is easy to check, but if there is an underflow error, the result is 0 and errno may or may not be set. If you want to be thorough, you'll have to test your implementation of strtold and if it doesn't set errno to ERANGE after a fault, do manual underflow checking...

>>59925085
Thanks m8, simple explanation, now I understand what people mean when they talk about garbage collection. I see how that could get confusing with complex programs. I hope switching to c++ will instill a more in depth understanding of programming and make me stronger overall.

>>59925017

>>59925334
>How will you know it won't fit?
?
because it fails in the condition

... n >= MIN && n <= MAX

and thus the whole return statement returns 0

puts(check_double("5.9e3600000") ? "valid" : "invalid");

returns invalid

It's slow as all hell when using opengl though.

>>59925660
That's the reason why it doesn't do it automatically. There's a lot of stuff in libraries and C has no namespaces, classes or anything like that to reasonably limit possible completions.

>>59925017
Most of these have a setup step and a basic mode. Clang complete has you specify a list of include folders which it parses for you and then (it seems to) limit what it can suggest based on your includes. They're never just right though. And as always they don't let you autocomplete of initial types. I want something that lets me type

_(variableOfTypeInt,

and have it suggest all functions taking an int as the first argument. It's so much better than completing based on the name when you're using your own structs.

With the MVVM pattern and WPF, if I have properties that are controls in the View Model or Model am I using the pattern wrong?

Say my Model has a property which is a RichTextBox. My View has its data context set to the ViewModel and binds the Model's RichTextBox to a ContentControl in the XAML.

The Model/ViewModel are still unaware of the View's existence so this should be okay, right

It looks like you're returning a copy of the list.

A suggestion would be to initialize list to the size of array, so that you don't have to continuously keep expanding the array (which adds a wee bit of overhead) if you know the size.

Aha! That's the exact reason I want to toy with this phone. Cyberpunk aesthetic. I actually have experience in cracking firmware too-- but really, there's shit-all I can do if I haven't got the slightest clue of the instruction set for the CPU I'm working with.

You are better off calling Qualcomm or their reseller than bugging a service rep of Samsung who is most likely offshored and has no idea what you want.

I'm building a flight controller for a drone for a project in my Micro-controllers class. We're using the TM4C123GH6PM and pretty much buying all of the other components for the drone. I've been messing around with getting RTC values to calculate the time between loop iterations for a PID algorithm and I'm curious; is there a better way than using the hibernate modules? I'm not sure if there are any repercussions to using that or if it's the right thing to use for a drone project. I guess I'm just not sure whether or not you can use the hibernate module in RTC mode without actually puting the Tiva in hibernate mode.

Anything Erlang can handle you can do in C or any other native language with a little effort put into developing the right framework.

There's nothing wrong with Erlang, and the fact that the VM is already there and well tested obviously saves you development time, but the retards who think that it's doing something magical that can't be achieved in other languages are annoying.

Haskell lacks dependent types and the entire proofing thing, it's easier to comprehend.

Also has amazing type inference.
