How to Install and Use Geany IDE on Linux Mint

Geany is a fast, lightweight, and versatile integrated development environment (IDE) for writing and editing code. It has support for over 50 programming languages out of the box, including C, Java, PHP, HTML, Python, Perl, and more.

In this comprehensive guide, we will walk through installing Geany on Linux Mint, setting it up for different languages, and using some of its key features for productive coding.

Installing Geany on Linux Mint

Geany is available in the default repositories of Linux Mint, so we can easily install it using the APT package manager. Here are the steps:

1. First, update your system‘s package index with:

    sudo apt update

2. Then install Geany:

    sudo apt install geany

3. Once the installation completes, you can launch Geany from the applications menu or by typing geany in the terminal.

And that‘s it! Geany is now ready to use on your Linux Mint desktop.

Installing Add-Ons and Plugins

Geany has a vibrant developer community that creates various add-ons and plugins to extend its functionality. Here are some useful ones to install:

• GeanyPyment: Provides auto-completion, documentation popups, and other features for Python.

• GeanyVC: Integration for Version Control systems like Git, SVN, and Mercurial.

• GeanyLatex: Supports autocompletion and compiling LaTeX documents within Geany.

• GeanyPG: Adds a plugin manager GUI to easily find and install plugins from within the editor.

To install these, search for them in the Software Manager or use apt install on the command line. Some plugins may need to be built from source, so consult their documentation for installation steps.

Configuring Geany for Development

When you first launch Geany, it uses some sane defaults for font, layout, color scheme etc. But you can customize it extensively to create your optimal coding environment.

Here are some of the configuration changes you should make:

Increase font size: Go to Preferences > Editor and set font type and size to your liking. I suggest a size of 14-16 px for comfortable coding.

Pick a color scheme: Go to Preferences > Editor > Syntax highlighting and select one of the many built-in color schemes for syntax highlighting. I personally like Cobalt, Shades of Purple or Monokai.

Set tab width: By default, tabs are 8 characters wide. You can change this in Preferences > Editor according to your preference.

Enable line numbers: Go to Document > Show Line Numbers to turn on line numbers – extremely useful while coding!

Set build commands: For compiled languages like C/C++, Java, or LaTeX go to Build > Set Build Commands and enter the appropriate gcc, javac, pdflatex commands to enable building and error checking your code within Geany.

Enable plugins: If you have installed any plugins, enable them in Tools > Plugin Manager to start using their functionality.

With these tweaks, you should now have a souped up Geany all ready for serious coding! Let‘s look at using some of its great editing features.

Handy Editing Features in Geany

Geany incorporates decades of user interface refinements seen in code editors and IDEs. Here is an overview of some very useful editing capabilities:

• Code Navigation: Navigate functions, variables etc quickly using the Symbols List sidebar.

• Auto-completion: Start typing a function name and Geany will pop-up suggestions to auto-complete it, based on existing code. Works for variable names and other constructs too.

• Call Tips: When you type a function and add a bracket, Geany automatically pops up a tooltip showing function arguments. Very helpful!

• Snippets: Right click and select Insert Snippet for quick code templates, e.g. a for loop template or even Hello World in many languages. Fully customizable too.

• Multi-Cursor Editing: Hold down Alt key while clicking/selecting to enable editing multiple lines together. Speeds up repetitive edits.

• Code Folding: Click the arrows in the gutter to collapse and expand functions, loops etc for better navigation in large files.

• Macros: Record multi-step edits as macros and replay on any part of code. Think of it as a programmable search-and-replace! Access via Edit > Macros.

These should help accelerate most common code editing workflows. But Geany offers even more advanced capabilities:

Advanced Geany Capabilities

Beyond the editor basics, Geany has quite a few tricks up its sleeve:

• GDB Frontend: Integrated debugging for C/C++ using the GNU Debugger, all within the Geany UI.

• Build System: Configure custom compiler commands for building, error checking and even running code for dozens of project types without leaving the IDE.

• Session Management: Save entire workspace including open files, bookmarks, breakpoints etc and restore on next launch. Persists edits across sessions.

• Tool Configuration: Every developer tool like Git, Make, Readline etc is configurable from within Geany to work just the way you expect.

• Lexers and Filetypes: Fully customize existing languages or even add new made-up languages with custom keywords, comments syntax etc.

• Plugin API: Extend almost any capability by developing plugins in Python or Lua. Or just use one of the existing 140+ plugins!

As you can see, Geany offers all the facilities expected in a modern IDE. Combined with its fast, lightweight footprint, it makes for an efficient programming environment.

Of course, being able to use the editor is one thing – understanding the language and APIs is another matter! So let‘s look at some resources for learning programming with Geany.

Learning Programming with Geany

Geany supports so many languages that you are bound to find one suitable for beginning programming. Here are some good resources:

• Python: The official Python 3 tutorial is the best starting point. GeanyPyment makes Python coding very enjoyable.

• Web Development: For front-end web coding in HTML, CSS, JavaScript – the MDN Web Docs is invaluable.

• C Programming: Read the classic K&R C book and use Geany‘s GDB integration to debug code.

• Java: Oracle‘s Java Tutorial trail covers Java in great depth. Use Geany‘s project support for easy Java builds.

• LaTeX: For academic writing, LaTeX Wikibook helps you leverage this document preparation system. GeanyLatex adds useful LaTeX authoring tools.

With its top-notch documentation and thriving community support across so many languages, Geany is undoubtedly one of the best free code editors for any programming endeavor.
