What’s new in 0.4.0

Mathematical Computing environment

Implemented the functionality of the scripts

Now you can create, open and save your scripts in formats.jl, .py, .txt.

Added commands for working with files

Now you can apply the following commands to files using the context menu or keyboard shortcuts:

  • ZIP

  • UNZIP

  • Rename

  • Copy

  • Paste

  • Cut

Cell management using hotkeys

Starting from this version, you can copy, paste and cut cells using the usual keyboard shortcuts cmd/ctrl + c, v, x.

Implemented a context menu for interactive script cells

Now the commands Copy, Cut, Paste, etc. are available for cells and through the context menu in interactive scripts by right-clicking.

Selecting lines with a click

We have implemented row selection by mouse click, row selection by ctrl+click, and group selection by shift+click.

Added the ability to create regular files

Now the user is not limited to .ngscript files and can specify any file extension.

Added file type sorting in the file browser

Many people are used to searching for their files among the same types. This makes it easier to work with the file browser.

Implemented the opening of the folder contents through the “arrow”

For your convenience, we have added the ability to open the contents of a folder by pressing the arrow on the keyboard.

Canceling an action using a keyboard shortcut

Now you can undo your last action using the usual combination of cmd/ctrl + z. This makes the routine easier and makes interacting with the environment more comfortable.

The ability to save the cell state

We have enabled the user to save the cell state (open, closed, hidden) in an interactive script, which is convenient for demonstrating the material when submitting a paper or, for example, giving a lecture, when the results or material need to be disclosed gradually.


The modeling environment

Added support for complex numbers

DSP specialists know that this entire application industry is based on a comprehensive analysis. And now Engee supports complex numbers for your DSP, radio and radar systems.

A new library of DSP blocks and dozens of new system objects

Continuing the theme of DSP, we have added dozens of system objects and blocks for the simulation environment so that you can design and create DSP algorithms, radars, radios, and more.

User Function block Engee Function

Many users have asked us about this. Now each of you can create any block in the Julia language and not be limited by the built-in library.

Implemented the selection of all objects on the canvas with hot keys

Added a convenient way to select all objects on the canvas using the keyboard shortcut Ctrl+A.

Implemented a different color for different types of lines and a ban on connecting lines and ports of different types.

For the convenience of the user, different types of lines have different colors, now you will not get confused in them. Engee will also help you if you try to connect different types of lines and ports.

Added smart window management

Now pop-up windows in Engee do not bump into each other when their size or browser window changes.

The ability to cut and paste a block Subsystem

Now you can copy entire subsystems from one model to another. This saves a lot of time during large-scale modeling.
