Many options to make UML diagrams in Linux

Linux is a very versatile operating system, in which you can find tools for almost anything. That’s why we can locate many programs to use. in other words, Linux is good for almost anything. In the case of UML is not the exception you can find some as:

DIA

Dia is an application for creating technical diagrams. Its interface and features are loosely patterned after the Windows program Visio. Features of Dia include multiple-page printing, export to many formats (EPS, SVG, CGM and PNG), and the ability to use custom shapes created by the user as simple XML descriptions. With this in mind, Dia is useful for drawing UML diagrams, network maps, and flowcharts.

Dia is available in the main repositories of the large Linux distributions, facilitating the installation process.

If you use Debian, Ubuntu or their derivatives:

:~$ sudo apt install dia

For Fedora:

:~$ sudo dnf install dia

If you use OpenSUSE:

:~$ sudo zypper in dia

Or if you use ArchLinux or derivatives:

:~$ sudo pacman -S dia

Its interface is simple, you just have to search in the category to UML and start drawing.

Now, for example, add an actor and a case of any use.

You can export it in different formats, such as PDF and JPG.

ArgoUML

ArgoUML is a UML diagramming application written in Java and published under the EPL License. Since it is a Java application, it is available on any platform supported by Java. To put it differently, you can use it on any Linux distribution and even on Windows or Mac. First, go to the downloads page:

Once downloaded, you must unzip it. And run it as another Java application. Type:

:~$ java -jar PATH_FILE.jar
:~$ java -jar argouml.jar

When you load the application, you will see the following:

As you can see there are lots of options for diagramming. I’ll make a class for you to see how it looks like.

It is also possible to display the code generated from the diagram. It supports C++, Java among others.

Like Dia, it is possible to print the diagram or export it as an image.

StarUML

StarUML is for many the most suitable option to work with UML diagrams. It is a powerful open source and multiplatform application with the goal of being a sophisticated software modeler for agile and concise modeling.

I must confess that it is my favorite application when I have to make a UML diagram, due to its flexibility and its many available options.

Supports code generation and reverse engineering for major programming languages including Java, C#, and C++ via open source extensions.

Its installation is very simple, go to its website and download it in appimage format.

Give him execution permission and run it with a double click.

:~$ chmod +x Downloads/StarUML-3.0.2-x86_64.AppImage

Once you start the application you will see something like this.

On the right side, by clicking the secondary mouse button, you can add a new diagram. I will make the class diagram.

As you can see, on the left side, you have the controls with which you can continue creating the diagram. For example, Association, aggregation, composition, dependency among others.

In conclusion, we can say that there are many professional tools to make UML diagrams in Linux. It’s up to you to choose the one that best suits your needs.

Today, let’s take a look at installing Inkscape on Linux.

• Ubuntu

Ubuntu is one of the most popular Linux distros for its user-friendly setup and working method. If you’re running Ubuntu, you can enjoy the software directly from Ubuntu’s repository. Just run this command:

sudo apt install inkscape

However, the software in the Ubuntu’s repository can be a little older than the absolute latest release. For enjoying the latest features with the latest edition, you have to add an additional PPA into your system. Run these commands:

sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt update
sudo apt upgrade -y

Then, run the previous command for successfully installing Inkscape on your system.

For uninstalling the software, run this command:

sudo apt remove inkscape

• Debian

If you’re a Debian user, Inkscape is already in the Debian repository. Run this command for installing the latest “stable” version.

sudo apt-get install inkscape

As you already know the working system of Debian, the software repository is hardly keeping pace with the progression of software. If you want to enjoy the latest version, scroll down and follow the instructions under “Universal” section.

• OpenSUSE

For installing Inkscape on OpenSUSE, run this command in the terminal:

sudo zypper in inkscape

For uninstalling, use this command line:

sudo zypper rm inkscape

• Fedora

Run this command for installing Inkscape:

sudo dnf install inkscape

Run this command for uninstalling Inkscape:

sudo dnf remove inkscape

• Arch Linux

Arch Linux is always a bleeding-edge Linux distro as everything in the repository always stays up-to-date. First, sync Pacman for downloading the latest database of available updates and patches.

sudo pacman -Syyuu

Then, install Inkscape by running this command:

sudo pacman -S inkscape

If you don’t need Inkscape anymore, feel free to uninstall it with the following command:

sudo pacman -R inkscape

• Universal

Inkscape is also available as a “snap” – a universal packaging of the software that can be run on any version of Linux given that the Snap core is installed in the system. Snap also makes managing software a lot easier. At first, you have to make sure that your system has Snap core installed. Follow the official tutorial of Snap here.

Inkscape is also available as a Flatpak package. This is also another solution like Snap. You have to install Flatpak core first.

Then, these commands for installing the snap/Flatpak version of Inkscape in your system. Don’t worry; there’s no difference with the software features. It’s just a packaging difference.

# Snap installation
sudo snap install inkscape

# Flatpak installation
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
sudo flatpak install flathub org.inkscape.Inkscape

Using Inkscape

When you open Inkscape first, here’s what you’ll get.

Now, enjoy all your editing and creativity with this super awesome vector editor.
