kandi X-RAY | aran Summary
Aran is a npm module for instrumenting JavaScript code. To install, run npm install aran. Aran was designed as a generic infra-structure for building various development-time dynamic program analyses such as: objects and functions profiling, debugging, control-flow tracing, taint analysis and concolic testing. Aran can also be used at deployment-time but be mindful of performance overhead. For instance, Aran can be used to implement control access systems such as sandboxing. Disclaimer: Aran is an academic research project, we are using it at our lab to support publications and run experiments. Although I spent a lot of time improving the quality of this software I do not claim it has reached industrial strength. Bugs may still remain and unforeseen behaviour may occur on large instrumented programs. In the near future, I will not add new features but will correct reported bugs.

QUESTION
I installed WSL2 on my Windows 10 Home. I want to use Maven (which I verified is installed correctly on Windows).
In an ubuntu shell from Windows Terminal, I set JAVA_HOME in my .profile
but it would not get set.
I ran these commands to try out the correct way to set JAVA_HOME but they do not work.
ANSWER
Answered 2021-Mar-11 at 15:00Workaround: (not an exact solution to the question)
Set the JAVA_HOME variable from Windows, via the gui and use Windows Powershell instead of ubuntu shell.
QUESTION
I have a data object that I want to put in URL API to fetch it using Axios, I've done my research but I didn't found any solution to convert this to an Url endpoint
This is simply my data objects :
...ANSWER
Answered 2021-Apr-25 at 01:02There are many options to do that. For static data i often use https://gist.github.com/.
Process:
- Create valid JSON from your javascript object. For example:
JSON.stringify(data, null, 2)
. - Paste the valid JSON text into the gist.
- Give it a file name that ends with .json
- Create the gist.
- Now just select the raw button and use that url for doing your get request.
Here i've created a public_url_endpoint with your data.

QUESTION
I found an elegant way to decorate a Python class to make it a singleton
. The class can only produce one object. Each Instance()
call returns the same object:
ANSWER
Answered 2020-Feb-06 at 16:31I suggest you choose a better singleton implementation. The metaclass-based implementation is the most frequently used.
As for for thread-safety, nor your approach nor any of the ones suggested in the above link are thread safe: it is always possible that a thread reads that there is no existing instance and starts creating one, but another thread does the same before the first instance was stored.
You can use a with lock
controller to protect the __call__
method of a metaclass-based singleton class with a lock.

QUESTION
I'm trying to get some hotels info from booking.com using Beautiful Soup. I need to get certain info from all the accomodations in Spain. This is the search url:
When I inspect an accomodation in the result page using the developer tools it says that this is the tag to search:
...ANSWER
Answered 2019-Dec-04 at 06:47JavaScript is modifying the page after it loads. So, when you use page.content
, it gives you the HTML content of the page before JS modifies the page.
You can use selenium to render the JS content. After the page loads, you can use driver.page_souce
to get the page source after JS modifies it and pass it to BeautifulSoup.
QUESTION
My goal is to remove options from a select input ("class") based on their classList depending on the selection made in a previous select input ("class-type"). Strangely enough, some options ARE removed (as they should be) when enableClassSelect
is called, but not all options which don't have the necessary class are moved at once. Currently the "class-list" needs to be changed ~7 times before ALL options are removed (this should not happen!).
See code below - I've reviewed it several times and attempted some debugging to no avail. console.log(classSelect.length);
prints "46", which is correct, so each option element should be checked in the iteration.
ANSWER
Answered 2019-Jul-05 at 04:17This is one way of doing it, not sure if it would be the fastest way, but it does work.
Essentially I removed all of the options from the HTML, and instead I am only adding on the correct options for that class type.
QUESTION
I need to display custom Autocomplete json data. The format of JSON file is:
...ANSWER
Answered 2019-May-05 at 19:00You have four main issues:
- The _renderItem call must be added to the autocomplete instance.
- You need to filter the resulting value you get into getJSON call.
- You need to use this._value() inside _renderItem callback
- You need to concatenate full_name and name fields when required.
QUESTION
I have the following test program:
...ANSWER
Answered 2018-Oct-28 at 11:41When you put special regex attributes in []
they lose their meaning and act like ordinary characters. That is why [./$]
is not working. Also, putting ^
inside square brackets means not to filter through all attributes inside it: [^./]
.
QUESTION
I have a python script with the following contents:
...ANSWER
Answered 2018-Sep-13 at 17:37The execution context is different. Within the REPL we are working line-by-line (Read, Eval, Print, Loop), which allows an opportunity for global execution scope to change in between each step. But the runtime executing a module is to load the modules code, and then exec it within a scope.
In CPython, the builtins namespace associated with the execution of a code block is found by looking up the name __builtins__
in the global namespace; this should be bound to a dictionary or a module (in the latter case the module's dictionary is used). When in the __main__
module, __builtins__
is the built-in module builtins
, otherwise __builtins__
is bound to the dictionary of the builtins
module itself. In both contexts of your question, we are in the __main__
module.
What's important is that CPython only looks up the builtins once, right before it begins executing your code. In the REPL, this happens every time a new statement is executed. But when executing a python script, the entire content of the script is one single unit. That is why deleting the builtins in the middle of the script has no effect.
To more closely replicate that context inside a REPL, you would not enter the code of the module line by line, but instead use a compound statement:
