Porcupine

Porcupine is an editor written with the notorious Tkinter library. It supports most things you would expect from an editor, such as autocompletions and syntax highlighting.

Most important features:

• Syntax highlighting (supports many programming languages and color themes, extensible)
• Autocompletions when pressing tab
• Jump to definition with Ctrl+click
• Langserver support
• Editorconfig support
• Git support
• Compiling files inside the editor window
• Running files in a separate terminal or command prompt window
• Automatic indenting and trailing whitespace stripping when Enter is pressed
• Indent/dedent block with Tab and Shift+Tab
• Commenting/uncommenting multiple lines by selecting them and typing a #
• Highlighting matching parentheses
• Line numbers
• Line length marker
• Find/replace
• Code folding
• Multiple files can be opened at the same time like tabs in a web browser
• The tabs can be dragged out of the window to open a new Porcupine window conveniently

Porcupine's design makes it very easy to customize. Almost everything is implemented as a plugin that can be disabled easily, but if you know how to use Python and tkinter, you can also make your own plugins. Porcupine plugins are so powerful that if you run Porcupine without any plugins, it looks like this:

Installing Porcupine

Development Install

See CONTRIBUTING.md for development instructions.

Debian-based Linux distributions (e.g. Ubuntu, Mint)

Open a terminal and run these commands:

sudo apt install python3-tk python3-pip python3-venv
sudo apt install --no-install-recommends tkdnd    # for drop_to_open plugin
python3 -m venv porcupine-venv
source porcupine-venv/bin/activate
pip install wheel
pip install https://github.com/Akuli/porcupine/archive/v2024.03.31.zip
porcu

To easily run porcupine again later, go to Settings --> Porcupine Settings and check "Show Porcupine in the desktop menu system". This makes Porcupine show up in the menu just like any other application.

You can uninstall Porcupine by unchecking "Show Porcupine in the desktop menu system" in the settings and then deleting porcupine-venv.

Other Linux distributions

Install Python 3.9 or newer with pip and tkinter somehow. If you want drag and drop support, also install tkdnd for the Tcl interpreter that tkinter uses. Then run these commands:

python3 -m venv porcupine-venv
source porcupine-venv/bin/activate
pip install wheel
pip install https://github.com/Akuli/porcupine/archive/v2024.03.31.zip
porcu

To easily run porcupine again later, go to Settings --> Porcupine Settings and check "Show Porcupine in the desktop menu system". This makes Porcupine show up in the menu just like any other application.

You can uninstall Porcupine by unchecking "Show Porcupine in the desktop menu system" in the settings and then deleting porcupine-venv.

MacOS

I don't have a Mac. If you have a Mac, you can help me a lot by installing Porcupine and letting me know how well it works.

I think you can download Python with tkinter from python.org and then run the commands for "other Linux distributions" above.

Windows

Download a Porcupine installer from the releases page and run it. Because I haven't asked Microsoft to trust Porcupine installers, you will likely get a warning similar to this one:

You should still be able to run the installer by clicking "More info". When installed, you will find Porcupine from the start menu.

Documentation

If you have just installed Porcupine, have a look at user-doc/getting-started.md. If you want to develop Porcupine, see CONTRIBUTING.md or dev-doc/architecture-and-design.md.

Most of Porcupine's documentation is markdown files in two folders:

• The dev-doc folder contains the documentation for developing Porcupine.
• The user-doc folder contains the documentation for using Porcupine.

FAQ

What's new in the latest Porcupine release?

See CHANGELOG.md.

Does Porcupine support programming language X?

You will likely get syntax highlighting without any configuring, and autocompletions with a few lines of configuration file editing. See this documentation.

Help! Porcupine doesn't work.

Please install the latest version. If it still doesn't work, let me know by creating an issue on GitHub.

Is Porcupine written in Porcupine?

Yes. I wrote the very first version in nano, but Porcupine has changed a lot since.

Why is it named Porcupine?

I think because I didn't find other projects named porcupine, but I don't remember exactly. Originally, Porcupine was named "Akuli's Editor".

I want an editor that does X, but X is not in the feature list above. Does Porcupine do X?

You can run Porcupine and find out, or create an issue on GitHub and ask. If you manage to make me excited about X, I might implement it.

Why did you create a new editor?

Because I can.

Why did you create a new editor in tkinter?

Because I can.

How does feature X work?

See porcupine/X.py or porcupine/plugins/X.py.

Why not use editor X?

Because Porcupine is better.

Is Porcupine based on IDLE?

Of course not. IDLE is an awful mess that you should stay far away from.

Is Porcupine a toy project or is it meant to be a serious editor?

Porcupine is meant to be a serious editor, in fact you might regret even touching it. https://www.youtube.com/watch?v=Y3iUoFkDKjU
