kandi X-RAY | xpl Summary
XPL is an easy to embed and extend scripting programming language. It's implemented in a single C header file within only several hundreds lines of code; and runs almost as fast as strlen(). It contains only a few high frequently used features like: if-then-elseif-else-endif, yield, scripting interface invoking etc. Registering the scripting interface is as easy as writing a common array. The design principle of XPL is doing 80% of work with 20% of core code, doing left work with few extended scripting interface. It's aimed to be a thin and light weight scripting solution. There's no build dependency, no heap allocation; just a single pass parsing + running.

QUESTION
I am trying to calculate some group-by items using Technical analysis library (TA-lib) here: https://mrjbq7.github.io/ta-lib/
Some of the functions such as AROON will generate two variables, AR_UP and AR_DOWN.
Without doing group-by, I would use the following:
...ANSWER
Answered 2021-Mar-14 at 07:15Does this work? It works for my example function but I couldn't install the package. Maybe it will work for your function too. groupby
followed by apply
doesn't work well with multiple return values.
QUESTION
I'm trying to receive stock data for about 1000 stocks, to speed up the process I'm using multiprocessing, unfortunately due to the large amount of stock data I'm trying to receive python as a whole just crashes.
Is there a way to use multiprocessing without python crashing, I understand it would still take some time to do all of the 1000 stocks, but all I need is to do this process as fast as possible.
...ANSWER
Answered 2021-Jan-31 at 19:18Ok, here is one way to obtain what you want in about 2min. Some tickers are bad, that's why it crashes.
Here's the code. I use joblib for threading or multiprocess since it doesn't work in my env. But, that's the spirit.
QUESTION
I've been using the crx-hotreload package to auto-reload my chrome extensions during development because it's annoying to have to click the refresh button on the Extensions page every time you make a change; however, this package doesn't work with MV3 because it uses the chrome.runtime.getPackageDirectoryEntry
method, which seems to have been removed from chrome.runtime in MV3. I can't find documentation to confirm that it was removed, but it's not there when I try to use it.
Does anyone know how to get access to all the files in the extension directory in Chrome Extension Manifest Version 3?
Or generally, is there a better way that I can hot-reload my chrome extensions during development that would work for MV3?
...ANSWER
Answered 2021-Jan-31 at 06:26This is one of many things based on DOM capabilities of background pages that are removed from ManifestV3 because service workers don't have DOM. For example, getPackageDirectoryEntry is using the old nonstandard FileSystem API in its returned value.
As to why, apparently the switch to service workers simplifies the internal source code in Chromium, even if it doesn't provide any real improvements for extension authors or users.
At this point all you can do is present a convincing use case and ask Chromium developers via https://crbug.com to implement an alternative API.
QUESTION
I have read Making an executable in Cython and BuvinJ's answer to How to obfuscate Python code effectively? and would like to test if the source code compiled with Cython is really "no-more-there" after the compilation. It is indeed a popular opinion that using Cython is a way to protect a Python source code, see for example the article Protecting Python Sources With Cython.
Let's take this simple example test.pyx

Answered 2020-Jun-16 at 18:41The code is found in the original pyx-file next to your exe. Delete/don't distribute this pyx-file with your exe.
When you look at the generated C-code, you will see why the error message is shown by your executable:
For a raised error, Cython will emit a code similar to the following:
QUESTION
I am trying to find out if Orbeon processes in parallel or in sequence.
We have a pipeline that fetches from 2 data sources and amalgamates in a single response. Does the processing below happen in parallel and combine when both sources have retrieved or is it sequential? If sequential, can it be made to be parallel?
...ANSWER
Answered 2020-Jun-12 at 17:56A pipeline won't run "in parallel", as in "using multiple threads", but it uses streaming.
In your case the URL Generator makes a request running the legislation.xq
XQuery in MarkLogic, and while it reads the data it passes it "down" to the rest of the pipeline, which transforms this data (assuming that your task-xml.xpl
and edit-xml-xmetal5.xsl
do something of that sort), and this is happening as the data is being received by the URL Generator from MarkLogic.
QUESTION
The short and immediate version of the question is: Why are these two regex different? i.e.,
href=(['"]).+?\1
vs
href=(['"]).+?['"]
or href=(['"]).+?(['"])
I am practicing regex on this site and I am trying to solve this level

I am posting the entire content here in case the site goes down in future.
...ANSWER
Answered 2020-Jun-06 at 23:34The backreference has to match the same thing that the capture group matched. So the first regexp will match
QUESTION
In GPFlow one can add a fitted mean function to the GP regression. When doing this as in the basic example, the result is, that there will be no uncertainties due to the uncertainty in the fit of the mean. E.g. in the example below the error bars don't grow outside the range of available data, as the slope of the linear mean remains fixed at its optimized value. Is there a way to account for these uncertainties, such that the error bands grow when extrapolating?
(The question was originally stated in an issue report but moved here to be more accessible)
...ANSWER
Answered 2020-Mar-24 at 08:53Most of GPflow's models only optimise for the MAP estimate of the hyperparameters of the kernel, mean function and likelihood. The models do not account for uncertainty on these hyperparameters during training or prediction. While this could be limiting for certain problems, we often find that this is a sensible compromise between computational complexity and uncertainty quantification.
That being said, in your specific case (i.e. a linear mean function) we can account for uncertainty in the linear trend of the data by specifying a linear kernel function, rather than a linear mean function.
Using your snippet with this model specification:

QUESTION
I have a backtrace like this, And I have the source code for xswiftbus
. Is there a way to find out to which codeline the "numbers" belong?
So could I figure out my callstack from that. Either in QtC or VS2017.
I personally cannot reproduce the crash leading to this backtrace, but maybe I can at least see which functions are involved.
...ANSWER
Answered 2019-Aug-28 at 15:27Download and install WinDbg.
Get the XPL file that matches the release (if possible, e.g. download that version) and rename it to DLL.
Choose "Start debugging" and then "open dump file", even if you don't have a dump file.
Select the renamed DLL file
Type
.symopt +40
