(version 3.5 or newer). On Windows, the Python engine is shipped with the program. On Unix-based systems, in order to make use of add-ons, Python has to be installed. The macOS doesn't include it, so it has to be downloaded and installed separately. On macOS the package including the 32-bit version is required. Also CudaText's ''Check for updates'' function requires Python.

Types of Add-ons

CudaText has 13 types of add-ons: * Code tree icons: Icon set, which is used in Code Tree panel. * File-type icons: Icon set, which is used in Project Manager panel and on tab captions. * Toolbar theme: Icon set, which is used on horizontal toolbar. * Toolbar x icons: Icon set, from which user can choose icons for user-added buttons. * Sidebar theme: Icon set, which is used on sidebar. * Lexer: Data file to support syntax highlighting for some language. * Plugin: Any Python-based extension. * Snippets: Set of files, which adds code "snippets" for some language, used with Snippets plugin. * Color theme: Set of colors for CudaText interface and its lexers. * Translation: Data file to support app localization to some language. * Linter: Sub-plugin for CudaLint plugin, which enables linting (source code checking) for some language. * Formatter: Sub-plugin for CudaFormatter plugin, which allows to re-format text for some language. * Tree helper: Plugin, which shows Code Tree structure for some language.

Examples of add-ons

Plug-in: CudaLint

This is the linting framework, which is the host for second level plugins, "linters". Each linter is capable to check validity of source code for some syntax. For example, linter based on CppCheck is capable to check C++ source code. Linters analyze source code and find errors/warning in it, and framework displays these warning in the CudaText bottom panel, and adds colored bookmarks for them. Initially, the framework was made based on Sublime Linter plugin for Sublime Text 3. Linters require additional command-line tools installed, e.g. CppCheck, CssLint and others. Sometimes, they require
