I am using vscode to develop pyspark, and I expect it to give me pyspark functions when I am writing code, for example in the below drop-down. I am getting some python functions when I say "df.", but it doesn't provide me with pyspark-specific functions. How to get this in drop-down?
Thanks,
Xi
Add below code to seetings.json in vscode
"python.languageServer": "JediLSP",

I'm trying to debug Rust in VS Code.
Following this answer, I installed CodeLLDB and was able to view all currently available variables in the IDE's variables window.
However, the values of some variables are not observable, e.g., nalgebra::Vector3<f64>. Meanwhile, I don't want to achieve this by println!, which I think is inefficient.
Do you have any suggestions?
I'm taking my first steps in SQLite3 in Python using VSCode. My problem is when I use a SQL command there isn't any syntax highlighting.
Is there any way to get the syntax highlighting?
Update
Thank you for your answer, but I've found one way: using Sublime Text.
example
It Seems that the SQL Command is just a String and all Editors Work this way and doesn't recognise code inside a String.
Anyways found some VS-CODE Extensions that might be of help,
Python String SQL
Highlight String Code
As in Julia REPL, we can type in latex styled variables by using tab and \epsilon to get the greek letter and give it a value. Since I mainly wirte Julia
codes in VS Code now, I was wondering if we could do that in vs code also? or can we do that in Jupyter notebook?
and in advance, can we have complicate latex styled computation formula in vs code when progrmming with the julia extension? or in Jupyter notebook
What I want to describe here is something very similar to what Mathematica can do, which makes the math equations much easier to read.
There is a VS Code Julia extension, which does support LaTeX-like tab completion, just like in the REPL. It should also just work in Jupyter, if you have the correct Julia kernel installed. You can find out more about that here.
In terms of a Mathematica style notebook workflow, Jupyter is probably the closest. Julia code still has to be regular Unicode text, so you can't expect your code to look exactly like free-form LaTeX, but you might want to look at Latexify.jl, which can convert Julia expressions and data structure into nice-looking LaTeX code. If you output LaTeX code generated by Latexify.jl in a Jupyter cell, it should even render correctly using MathJax. Otherwise, you can also just write LaTeX formulas inside Markdown cells with Jupyter.
I've been learning Swift for a little bit now, and I really want to use it. However, compiling Swift on Windows is quite a chore. I can do it from Visual Studio 2015 easily, but VS2015 support is very poor, and incredibly hard to work with; I would prefer to use Atom and the command line. I use RemObject's Silver to compile to .NET, but I can never get the command line to work.
When I use the Elements.exe at C:\Program Files (x86)\RemObjects Software\Elements\Bin, passing the filename as a parameter, it tells me that print is undefined.
Does anyone know how to use Silver's command line to compiler Swift?
Have you tried referencing the online documentation?
calling elements needs some libraries to import:
elements --mode=ECHOES --reference=Swift myfile.swift
I recommend using MSBuild, rather than Elements.exe, to build Elements projects from the command line. It's more complete and supports more advanced build tasks needed for some project types.
That said, --mode and --reference should definitely work. Can you post a complete command line and output?
You will need --reference=Swift in order for print() & co to be known, and --reference System.Core to use LINQ.
Is there a way for "ipython3 notebook" to receive command line arguments with its 'run' button?
Thank you very much.
I just encountered this problem when I tried to run some scripts using argparse library in Jupyter Notebook. Since I don't want to do much modification to the code, I needed to provide sys.argv[] to the parser.
In my case, such code can solve the problem:
import sys
sys.argv=['self.py','arg1','arg2']
Because in a real command line, the first element of sys.argv is the name of the script, so you have to provide a random script name or a name that suitable for your application, and the following arguments are just like they are passed by a real command line.
This works for me so far, but I don't know if it is safe and elegant, wish this could help you.
Do you mean the Cell -> Run menu item? If so, no. The notebook's not really designed to be used like that. What are you trying to do?
