Komodo Edit for Mac from ActiveState is a free, open source, multi-platform, multi-language editor (PHP, Python, Ruby, Perl and Tcl, JavaScript, CSS, HTML and template languages like RHTML, Template-Toolkit, HTML-Smarty and Django). Background syntax checking and syntax coloring catch errors immediately, while autocomplete and calltips guide you as you write. Available on Windows, Mac OS X and Linux. XPI extensions allow you to create your own plug-ins. XPI extension support provides the same capability as Firefox, with all standard Mozilla APIs based on XUL, XBL, and XPCOM, plus own for Python and JavaScript. Other features include Vi emulation, Emacs keybindings, code folding and code snippets.
Features and Highlights
Track Changes
The editor has gained a new left margin, which highlights unsaved changes, as well as any uncommitted SCC changes. Clicking on the margin shows a diff dialog of the changes, and allows you to revert individual changes. Sweet!
Commando (Go to Anything)
This powerful popup dialog is the combined successor of the Fast Open and Invoke Tool dialogs in previous versions of Komodo. Commando provides fuzzy matching, match highlighting, search for files (find any file under a folder), toolbox search, bookmark integration, shortcuts (go-tool) integration as well as custom category filtering.
GoLang Support
Google Go (GoLang) is now supported in Komodo, and features syntax coloring, code folding, syntax checking (linting) and code intelligence
Markdown Viewer
For Markdown files, Komodo provides a preview of the generated HTML directly within a Komodo split view and contents dynamically update whenever you make a change to the Markdown text - it doesn't even need to be saved.
Kopy.io Helper
Like pastebin, now you can easily share snippets of code with other people directly from Komodo. Simply make a text selection and use the editor: right-click context menu and choose Share Code via Kopy.io. Kopy.io supports client side encryption, so you can make those shared pastes more secure.
Color Schemes and Themes
'We've updated the Komodo color schemes and we've made Tomorrow_Dark the new default Komodo color scheme (a dark-based scheme). The Komodo UI has been updated to match the latest operating systems, so Komodo now looks even better. We also added the ability to tweak the editor line height spacing.'
Notifications
Notification messages shown to the user now appear in a separate popup panel that overlays the main Komodo editor window (they previously appeared in the Komodo statusbar). This makes for more intuitive and informative use of Komodo; no more asking yourself 'What just happened?'.
Language Icons
Language icons have been overhauled to be consistent and easily identifiable by their colors and emblems. Komodo dynamically generates new icons for filetypes that it has not previously encountered, so you'll always have unique icons for each language.
New Developer SDK
An overhaul of the Komodo APIs makes it easier to load and access the methods inside of Komodo. We're now making use of CommonJS (aka Node.js) require() calls to load individual modules.
Note: Requires 64-bit processor.
