This simple extension treats the text of the active text editor document as a matrix (where elements are separated by whitespace) and offers some simple matrix operations.
https://marketplace.visualstudio.com/items?itemName=ractive.textmatrix
To apply an operation, open the command palette in vscode (F1 or ctrl-shift-p) and search for one of the commands described below (or search for textmatrix to find all commands). The commands are also availble in the context menu of the editor that is accessible by right clicking in the editor.
Be aware that the text in the currently active editor window (representing a matrix), is replaced with the result of the matrix operation.
The text must represent a rectangular matrix with the exact same amout of elements on each line, separated by whitespace. A simple, valid matrix e.g. is:
1 2 3
4 5 6
or
1 2 3 4
5 6 7 8
The resulting matrix of the operation is always printed out with one space between every element.
The available commands in vscode are:
Transposes the rows and columns of the text:
1 2 3
4 5 6
becomes:
1 4
2 5
3 6
Flips the elements on each row (x axis):
1 2 3
4 5 6
becomes:
3 2 1
6 5 4
Flips the lines of the text:
1 2 3
4 5 6
7 8 9
becomes:
7 8 9
4 5 6
1 2 3
Rotates the matrix by 90 degrees:
1 2 3
4 5 6
becomes:
4 1
5 2
6 3
Rotates the matrix by 180 degrees:
1 2 3
4 5 6
becomes:
6 5 4
3 2 1
Rotates the matrix by 270 degrees:
1 2 3
4 5 6
becomes:
3 6
2 5
1 4
This extension can be used to manipulate images in https://arcade.makecode.com. Copy/paste an image as text (from the javascript source) to a vscode window and flip it or rotate it easily with on of the matrix operations.
