kandi X-RAY | aran Summary

aran is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. aran has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i print-lite' or download it from GitHub, npm.

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.

            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.

            There are many options to do that. For static data i often use https://gist.github.com/.

            Process:

            1. Create valid JSON from your javascript object. For example: JSON.stringify(data, null, 2).
            2. Paste the valid JSON text into the gist.
            3. Give it a file name that ends with .json
            4. Create the gist.
            5. 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.

            Answered 2020-Feb-06 at 16:31

            I 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.

            JavaScript 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.

            Unable to remove options from select with JavaScript iteration?
            Asked 2019-Jul-05 at 04:42

            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.

            This 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.

            You have four main issues:

            1. The _renderItem call must be added to the autocomplete instance.
            2. You need to filter the resulting value you get into getJSON call.
            3. You need to use this._value() inside _renderItem callback
            4. You need to concatenate full_name and name fields when required.

            When 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

            Why does deleting a global variable named __builtins__ prevent only the REPL from accessing builtins?
            Asked 2018-Sep-13 at 17:37

            I have a python script with the following contents:

            ...

            ANSWER

            Answered 2018-Sep-13 at 17:37

            The 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:

            Install aran

            The code transformation performed by Aran essentially consists in inserting calls to functions named traps at ESTree nodes specified by the user. For instance, the expression x + y may be transformed into META.binary("+", x, y, 123). The last argument passed to traps is always a serial number which uniquely identifies the node which triggered the trap. The object that contains these trap functions is called the advice and the specification that characterises what trap should be triggered on each node is called the pointcut. The process of inserting trap calls based on a pointcut is called weaving. This terminology is borrowed from aspect-oriented programming. When code weaving happens on the same process which evaluates the weaved code, it is called live weaving. Live weaving enables direct communication between an advice and its associated Aran instance. For instance, aran.nodes[serial] can be invoked by the advice to retrieve the line index of the node that triggered a trap. Another good reason for the advice to communicate with Aran arises when the target program performs dynamic code evaluation -- e.g. by calling the evil eval function.

            Support

            When dynamically analysing a program, it is implicitly assumed that the analysis will conserve the program's behaviour. If this is not the case, the analysis might draw erroneous conclusions. Behavioural divergences caused by an analysis over the target program are called Heisenbugs. It is very easy to write an analysis that is not transparent, for instance advice.primitive = () => "foo"; will drastically alter the behaviour of the program under analysis. However, Aran introduce Heisenbugs by itself as well:.
