If you set up your build system correctly, Boost is fine if you use it very sparingly and with libraries that are smaller.

It can slow your compile down to a crawl if used incorrectly though.

I know I'm lttp for js spa talk, but at the risk of shaggaring I have the horrible opinion that asp.net core mvc with plain ol' razor views is the pinnacle of webdev right now. I want server-side rendering and jfc get nodejs away from me eww gross

The worst thing MS dotnet team has done in a while, is rolling all the frontend js poo poo into the default templates.

So I generally think boost libraries (with some notable exceptions) are pretty usable, if a little over-engineered and quirky. But boost::filesystem in contrast seems really under-engineered and full of surprises. For example, I'm trying to write a function which copies a few directories recursively. It seems like the copy itself should be as simple as:
C++ code:
fs::copy(source, destination);
But that runs into this wild segfault. Okay though, that seems like it might be apple's fault, so we won't hold it against boost::filesystem. And there's a workaround:
C++ code:
fs::copy(source, destination, ec);
if (ec) {
    throw std::runtime_error(std::string("Error copying ")
    + source.native() + " to "
    + destination.native() + ": "
    + ec.message());
}
Except that doesn't do what you think it does. When copying directories (like source and destination), boost::filesystem doesn't actually recursively copy the directory (like you would expect), but instead just creates a new directory at the destination with the same attributes as the source directory.

...Fine, we can work around that again.
C++ code:
for (auto& entry: fs::recursive_directory_iterator(source)) {
    auto relative_dest = entry
        .path()
        .lexically_relative(source)
        .lexically_normal();
    auto absolute_dest = destination / relative_dest;
    fs::copy(entry.path(), absolute_dest, ec);
    if (ec) {
        throw std::runtime_error(std::string("Error copying ")
        + source.native() + " to "
        + destination.native() + ": "
        + ec.message());
    }
}
Why make such a simple function so complicated?

(and no, I can't use std::filesystem from c++17, since it's been an uphill struggle making sure that I can count on c++11 being present on all the machines I want to run this on)

lol they overloaded the / operator for joining paths?

CLion's integrated code analysis by clang-tidy is nice, though it chugs on analyzing complex projects that bring in like TBB or Boost (it might have improved a bit with the 2018 releases). the UIs they wrap around LLDB/GDB and AddressSanitizer are nice too

I found it rather invaluable for quickly getting up to speed on larger C++ codebases

okay its me the terrible programmer. im writing some javascript (Actually CoffeeScript but whatever) app and im getting a little frustrated with promises, at least in a particular situation

since im on CoffeeScript 1.x, I dont have async/await available to me. otherwise I could do this

code:

results = []

for item in items
	temp = {}
	temp["a"] = await someAsyncFunction(item)
	temp["b"] = item.someProperty 
	results.push temp

and all would be well in the world. what ive resorted to is this..... thing

code:

promises = []
results = []

for item in items
	temp = {}
	tempPromise = someAsyncFunction(item)
	promises.push tempPromise
	temp["a"] = tempPromise
	temp["b"] = item.someProperty 
	results.push temp

Promise.all(promises)

which works, I guess, the object assigned to temp["a"] is a promise and not the actual result of that promise, but I can at least get to it in some way

I'm actually fine with that. In the context of paths, it's pretty clear that / doesn't refer to division, so overloading it adds convenience without hurting readability (personally I'd say it improves readability). Also I think overloading / for paths is pretty common in languages with operator overloading; for example python's pathlib does it too.

that's why I like J. most of its horrible linenoise operators are language builtins.

code:


quicksort=: (($:@(<#[), (=#[), $:@(>#[)) ({~ ?@#)) ^: (1<#)

(well, technically they might be in the standard library. Still, it's way more brazen than Haskell.)

Usually when the question of apps comes up, it's because the person involved in the sales process who doesn't know what the gently caress they're talking about has been told that you must have an app and no telling them that a webpage will work just fine will satisfy them.

If you can answer "yes" to the "do you have an app?" question they'll be happy. No requirements for what that app should do or indeed any idea of why they demanded it. Slap the web page into an app, watch as nobody downloads it but still be able to answer yes to the app question during the sales process.

it's terrible in python as well, maybe worse since python code tends to be less overload-crazy in general

your non-async version is technically 'better' here because it can run all the someAsyncFunction calls in parallel, which may or may not matter more than code clarity
i would expect something maybe like

code:

var promises = items.map(item => someAsyncFunction(item)
    .then(result => ({a: result, b: item.someProperty})));
return Promise.all(promises);
