Erlang: How to include libraries

一曲冷凌霜 提交于 2019-12-05 18:44:27
I'm writing a simple Erlang program that requests an URL and parses the response as JSON. To do that, I need to use a Library called Jiffy. I downloaded and compiled it, and now i have a .beam file along with a .app file. My question is: How do I use it? How do I include this library in my program?. I cannot understand why I can't find an answer on the web for something that must be very crucial. Erlang has an include syntax, but receives a .hrl file. Thanks! You don't need to include the file in your project. In Erlang, it is at run time that the code will try to find any function. So the

My code myDb = openOrCreateDatabase("/sdcard/FashionGirl/ImagesDB.db", Context.MODE_PRIVATE, null); myDb = openOrCreateDatabase(dbPath, Context.MODE_PRIVATE, null); worked perfectly, but was giving warning Do not hardcode "/sdcard/"; use Environment.getExternalStorageDirectory().getPath() instead So I tried, String dbPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "FashionGirl/ImagesDB.db"; myDb = openOrCreateDatabase(dbPath, Context.MODE_PRIVATE, null); But strangely, its not working, where Environment.getExternalStorageDirectory().getAbsolutePath() has value /storage So

左心房为你撑大大i 提交于 2019-12-05 13:51:33
问题 I am very new to typescript. Whatever typings I try to install, I get: typings ERR! message Attempted to compile "angular" as an external module, but it looks like a global module. I am just trying to do typings install dt~angular What am I doing wrong? Update: If you are coming here with little knowledge (as I was when writing this question) - consider using npm/@types. More info and discussion. 回答1: As error message suggests, you should use --global option: typings install dt~angular -

Time an external program whose output is being processed by Python

安稳与你 提交于 2019-12-05 13:12:05
I want to measure the time of execution of an external program whose output is used by my Python script. Calling extprogram the program that produced the output, at the moment I do something like: import time import subprocess def process_output(line): ... ... return processed_data all_processed_data = [] ts = time.time() p = subprocess.Popen("extprogram", stdout=subprocess.PIPE) for line in p.stdout: all_processed_data.append(process_output(line)) te = time.time() elapsed_time = te - ts This doesn't work as intended because what I am measuring is the time of execution of extprogram plus the

Load external Javascript on function call

こ雲淡風輕ζ 提交于 2019-12-05 08:01:25
I would like to know how to load an external Javascript into my document from a function. seth This is one way: function loadDaFun() { var script = document.createElement('script'); script.src = '/path/to/your/script.js'; var head = document.getElementsByTagName("head")[0]; head.appendChild(script); } CMS The @seth 's answer is completely right, but you don't need to leave the inserted script element on the DOM, you can remove it just after it is loaded, and also you might want to know when the inserted script is ready to use, for example you can: function loadScript(url, completeCallback) {

twisted logic: a global variable in one file refers to an extern variable but is also referred by that extern variable

為{幸葍}努か 提交于 2019-12-05 06:31:28
fileA.cpp: #include <iostream> extern int iA; extern int iB= iA; int main() { std::cout<<iA<<','<<iB; } fileB.cpp extern int iB; extern int iA = 2*iB; Compiled and linked and ran, out come in the debug and release mode is 0,0 My question is how it works, why there is no issue in linking stage? I'm using VC++2003. The initialiser overrides the extern keyword, so there's nothing "magical" about this: you're just declaring and defining two completely unrelated variables in different functions. [C++14: 3.1/2]: A declaration is a definition unless it declares a function without specifying the
