There are some green upside arrows and red downside arrows with some numbers beside them in code completion window in Pycharm 2020.
I really don't have any clue what these arrows and numbers stand for.
You can see a sample of it in below image.
What is the meaning of the arrows and numbers?
Any help would be appreciated.
I've figured out this option is related to Machine Learning Code Completion plugin that is bundled with pycharm and is available via Settings>Editor>General>Code Completion>Machine Learning-Assisted Completion>Rank completion suggestions based on Machine Learning.
And this numbers are some sort of ranking.
Plugin doc says:
The plugin improves code completion feature by reordering of elements in the completion popup by ranking more relevant items higher using machine learning.
Those green ↑ or red ↓ has similar meaning as arrows used in foreign exchange rates:
but instead of rise / drop in the rate, they show rise / drop in applying them to your code, and – consequently – the change of their position in the completion popup.

Qt Creator has a really nice feature where based on the cursor location, they change the background color of the rest of the buffer to make it easy to see the block of code one is working in. They have two levels of highlighting - please see picture.
I've been trying to recreate this in VSCode but with no luck.
I tried various VSCode settings and they don't seem to scope down to the block.
Blockman is visually very noisy i.e. I'd really like to have the lines have the background changed.
Blockman is visually very noisy
Hello, author of Blockman here. Blockman has so many configurations that can be used to reduce the noisy visual of default Blockman behavior. You can hide all blocks and show only the focused block. Also you can show +-1 or +-2 or +-3 ..... depth blocks from the focused block, or from the ground block, or both. Also you can hide all backgrounds and show only borders. And there are also many more settings. Please see the GIF instructions and textual instructions on Blockman page:

Also this instruction is useful:

I am writing a small tools for VS Code and the tool will need to draw arrows between symbols in the code.
Something along these lines.
Please forgive my skills with Paint.
What it is the best way to achieve this effect in VS Code?
What you want is not possible. The editor output in vscode is a list of DOM nodes (divs for the lines, spans for the syntactic elements). You cannot draw lines between DOM nodes.
If you had full control over the editor you could add an overlay over the entire text to draw the lines, but then you have to take care not to disturb the normal behavior of the editor and, after all, you don't have that kind of control.
A webview is not a good approach, as it would not only require to duplicate the work the normal editor does, it's also isolated and has no direct access to the main application, which means actions, language server support etc. don't work
yes sure use this Rainbow Brackets
its draw an arrow between the start and the end .
enter image description here
I have developed a VS Code Box Drawing extension which works by using selection's start and end positions to work out a level rectangle between the two positions in the text and replaces the edge characters of the rectangle with Unicode box drawing characters.
This works great with a selection start and end positions provided, but it also requires at least white space to already extend all the way to the right edge of where the box is supposed to end, otherwise the selection cannot be made that far.
I would like to achieve two things:
Be able to use mouse events and figure out would-be positions from them even if they extend beyond the length of the lines, so that I can back-fill the missing line length with white-space as I go drawing the box.
Be able to draw arrows (simple enough using the Bresenham's line algorithm).
I have read the Visual Studio Code API Reference and it has only one mention of the mouse pointer in this section underneath the languages header:
The rest, like tracking the mouse, positioning the hover, keeping the hover stable etc. is taken care of by the editor.
I have also read through the Extensibility Reference finding nothing relevant to what I aim to achieve.
This extension only makes sense for monospaced fonts, so additionally, I'd like to find out if there is a way to tell if the editor font is monospaced so I can reject extension activation with an error if that's not the case.
This is something the VS Code team doesn't currently enable (not a part of the extension API) not wants to enable in the near future:
I think that exposing mouse events to the extension API is not something that we'd be likely to add
Source comment on GitHub
I did not notice in the previous version of Eclipse but in Eclipse Mars, there is a small yellow star sign left to the recommended thing.
What is the meaning of it?
Both the star and the percentage are added by the Intelligent Code Completion.
Follow this Link for more http://www.eclipse.org/recommenders/manual/#intelligent-code-completion
These suggestions are based on context and code analysis (data mined) of similar situations. The percentage is presumably an indication for the confidence of that suggestion.
Protected methods are in fact indicated by a yellow diamond with rounded corners, similar to the icon in the outline view.
My brother wanted to introduce me to lisp languages, so he showed me DrRacket on his computer. Everything looked awesome, including arrows that point to where a function is being imported from, and a documentation bubble of sorts that tells you the syntax for a function.
I downloaded DrRacket onto my computer, however I don't have either of these. They are definitely not required, but they would make learning much easier.
According to my brother, he "spammed a bunch of Emacs shortcuts by accident, and it just sort of happened."
If anyone could help me, it would be much appreciated.
These features are provided as part of DrRacket's background expansion, which can be enabled or disabled in the "Background Expansion" tab of DrRacket's preferences.
Enabling background expansion causes DrRacket to constantly perform macro-expansion as you edit your program, which will automatically detect syntax errors as a helpful side-effect.
Once background expansion has completed for a program, binding arrows and documentation blueboxes will be enabled (provided you've checked the relevant checkboxes in the background expansion preferences).
In some especially complex programs that employ a large number of macros, background expansion can take a non-trivial amount of time, though it shouldn't take any more than a few moments for all but the most complicated of programs. The current state of background expansion is displayed in the bottom-right corner of DrRacket's editor window.
Once background expansion has completed, the indicator circle will turn green, and all program analysis tools such as arrows, documentation bubbles, and refactoring will become available.
If you don't want to use background expansion for some reason, you can manually trigger the syntax analysis DrRacket provides by pressing the "Check Syntax" button in the DrRacket toolbar.
This enables the binding arrows and documentation bubbles, and it also colorizes the source code using more advanced syntax highlighting that provides some additional information about the way bindings are used (this feature is only provided by Check Syntax, not background expansion).
