Komodo IDE/Edit 4.1 (May 15, 2007)

Highlights in Komodo 4.1

Ruby on Rails

  • Ruby on Rails project template: Makes getting started and working with a Rails project much easier. Includes integration for many Rails project commands.
  • Ruby completion: Added support for space-based calltips (common in RHTML template code) and other Rails completion improvements.
  • Re-written Ruby debugger engine: Based on ruby_debug, the new engine is 50-60 times faster.

Code Intelligence

  • Autocomplete for the Komodo's JavaScript API (i.e. the "ko" namespace) when editing JavaScript macros in an editor tab. Also documentation for the "ko" namespace in the Reference section of the Komodo docs.
  • PHP 5.2: stdlib changes for autocomplete/calltips.
  • MXML/ActionScript support: Added schema-based XML autocompletion for MXML files and syntax highlighting for embedded ActionScript.
  • JavaScript completion: Added support for JSDoc autocomplete and calltips and autocomplete on string literals.


  • Tab Stops
  • Vim registers
  • Add commands to fold/expand blocks of code recursively (View|Fold|Expand Recursively & Collapse Recursively). (Bug 27264)
  • Support editing macros in a full editor tab (via "right-click|Edit" on a macro).

Other Improvements

  • Added a JavaScript tutorial to introduce some of Komodo's JavaScript features.
  • Support editing macros in a full editor tab (via "right-click|Edit" on a macro).
  • Find/Replace: Default (pre-populated) search pattern is now the previous search rather than the word under the cursor.
  • Status bar: Added selection info ("Sel:") status bar panel.
  • Add more icons from famfamfam that can be used for custom commands, macros, etc. in the Toolbox and Projects.
  • Komodo installations now include a "Komodo SDK" with Komodo's core IDL and the 'xpidl' utility necessary for building PyXPCOM components for user extensions.
  • Significant refactoring of the Komodo JavaScript API under the "ko" namespace (e.g. "ko.dialogs.alert(...)" instead of "dialog_alert(...)"). Old APIs remain for backward compatibility for JavaScript macros -- but they will eventually be removed. This is an ongoing process: documentation and autocomplete (when authoring macros) will be added in subsequent releases.
  • Rx integration (IDE-only) and regular expression help in the Find/Replace and Find in Files dialogs.
  • Several bug fixes

Highlights in Komodo 4.0

Code Intelligence

  • Redesigned Code Intelligence system: CSS, JavaScript, Perl, PHP, Python, Ruby, Tcl and XML support have been re-implemented with a new code intelligence system, providing improvements in autocompletion, calltips, the code browser, and overall performance.
  • Go to Definition: A new option for quickly jumping to the definition of a code object (e.g. a variable, a subroutine, a module, etc.) under your cursor.
  • Schema-based XML Autocomplete and CallTips: Komodo now supports autocomplete and calltips support for XML and HTML based on DTD or RelaxNG Schema. SGML and XML Catalogs are supported.
  • API Catalogs: Autocompletion for several popular JavaScript libraries can be enabled in Preferences.
  • DOM Viewer: A new tab in the left pane shows the DOM structure of XML and HTML documents in a tree view. Double-clicking on a node in the DOM Viewer moves the cursor to the corresponding node in the document. Komodo IDE only
  • User-Defined Languages: Komodo 4 introduces a system for adding custom language support called UDL (User-Defined Languages) which allows Komodo to properly syntax-color multi-language files and template files common in many web programming frameworks. Also included is a tool called Luddite which you can use to define custom language syntax-coloring and package those into Komodo extensions.
  • New languages: Support for Template-Toolkit, HTML-Mason, Smarty, Django, and Luddite has been added using UDL


  • Vi emulation: Modal key bindings which emulate the navigation, text insertion, visual selection and command-line modes of Vi and Vim. Custom commands can be implemented by adding Komodo macros to a Vi Commands Toolbox folder.
  • Configurable Background Syntax Checking: The frequency of background syntax checking is now configurable, improving editor responsiveness in large files.

HTTP Inspector Komodo IDE only

  • HTTP Inspector: An interface for examining HTTP requests and responses as they happen. It runs a local proxy which intercepts HTTP traffic and records each transaction for analysis. The Inspector can break on a request or response, which can then be edited and submitted in its modified form.

JavaScript DebuggingKomodo IDE only

  • JavaScript Debugging: Komodo now offers JavaScript debugging using the Firefox web browser and the JavaScript DBGP extension. With the extension enabled, loading JavaScript or triggering JavaScript controls in the browser window opens a debugging session in Komodo, which loads the relevant JavaScript code.
  • JavaScript Interactive Shell: An interactive shell for manipulating JavaScript code is available within JavaScript debugging sessions. This shell is similar in functionality to the other interactive shells in Komodo.


  • Live Folders: Komodo projects now offer Live Folders which display current filesystem contents. The previous folder behavior is still available; these folders are now referred to as "Virtual Folders" in the documentation. By default, new projects are created with Live Import, making the project behave as a Live Folder. Project-specific Directory Import preferences define which files and directories to include.
  • Project Settings: All project settings are now in the Project Properties dialog. This dialog box is now used for files, folders and projects, displaying the appropriate properties for each type.
  • Project Templates: Projects templates can be created and used when creating a new project.
  • Additional Project functionality, including:
    • Project based debugger preferences
    • Basic file management (Delete, Rename, Show in File Manager)
    • Project import from remote file systems
    • New File option

Other Improvements

  • SCC History: A new option has been added to the Source Control menu which displays the revision history of a file. You can compare (diff) two selected revisions from the list, or select one and compare it to the local copy. Komodo IDE only
  • SFTP and SCP: Komodo now supports access to remote files via SFTP and SCP. Saved password information for all remote servers is stored securely in Mozilla's native password manager.
  • Help Browser: Komodo now uses Mozilla's help browser for displaying Komodo help.

Komodo 3.0 (July, 2004)

Code Intelligence

Komodo's Code Intelligence system is a set of tools that supports multiple languages. The Code Intelligence tools include the Code Browser, Object Browser and Python AutoComplete and CallTips. All Code Intelligence tools require a Code Intelligence database to operate fully.

The Object Browser is a graphical browser that searches the Code Intelligence database for specified code symbols and modules. Use the Object Browser's preview pane to view code snippets containing the search criteria.

The Code Browser displays on the Code tab next to the Projects tab in the Left Pane. The Code Browser displays a hierarchical tree view of all code constructs (for example, variables, methods, imports) in all open files. For Python, instance attributes are all displayed. The code tree, which can be navigated using either the keyboard or mouse, includes the following features:

  • Double-click a node to jump to that point in the code.
  • When the cursor is positioned in the Editor Pane, clicking the Locate current scope button on the Code Toolbar or pressing 'Ctrl'+'K', 'Ctrl'+'L' causes Komodo to jump to the node in the code tree that most closely matches the current point in the program. Additionally, a Scope Indicator, located in the status bar, displays the current scope of a selected code construct. Double-click the Scope Indicator to open the tree hierarchy to the code construct.
  • When the focus is in the Code Browser tree, pressing the 'Tab' key causes Komodo to shift to the Filter text box. Typing any string in this text box causes the Code Browser to display all of the nodes matching that string. Pressing 'Tab' again shifts the focus back to the tree. Clearing the Filter text box returns the tree to its original state. Note that all matching nodes are shown, even those that are invisible because their parents were not "expanded".
  • The Sort menu on the Code Toolbar lets you toggle whether the nodes at each level of the tree are sorted in alphabetical order or according to the order they occur in the file.
  • The Code Description pane, located in the lower part of the Code Browser, displays additional documentation (when available) on various program components.

Python AutoComplete and CallTips are enhanced with the Code Intelligence database.

Interactive Shell

The interactive shell is an implementation of Perl, Python and Tcl's interactive shell within Komodo. The interactive shell supports, AutoComplete, CallTips, debugging functions, customization and history recall.


  • A debugger proxy is available that enables multiple users to debug with Komodo on the same machine.
  • The Breakpoints tab in the Bottom Pane of the Komodo workspace is designed for convenient management of breakpoints and Tcl spawnpoints. This tab displays enabled and disabled breakpoints and spawnpoints. Double-clicking an enabled or disabled breakpoint on the Breakpoints tab opens the related file in the Editor Pane and shifts focus to the line in the program associated with that breakpoint.
  • Komodo now handles multi-session debugging. Komodo can debug multiple programs, regardless of the supported languages used in the applications being concurrently debugged.
  • The Bottom Pane of the Komodo workspace (previously the Output Pane) has been reorganized and enhanced. The new Debug tab is displayed whenever a Komodo debugging session is launched.
  • A Debug Toolbar is available on the Debug tab in the Bottom Pane of the Komodo workspace. It includes additional controls for detaching from a new debugging session and forcing a break.
  • New remote debugging features include the ability to listen for remote debugger sessions continuously, set remote debugger preferences, and check the listener status of the current configuration.
  • The new debugger properties dialog box supports multiple 'configurations' to be saved per file.
  • The new Debugger dialog box (displayed when a debug session is invoked) supports configurable interpreter arguments.
  • The Disable Output Buffering and Enable Implicit Flush options for PHP debugging have no effect when Simulate CGI Environment is selected. To disable output buffering in CGI emulation mode, manually comment out the output_buffering setting in php.ini with a ";" character, or set it to "off".

Rx Toolkit

The Rx Toolkit has been completely overhauled. New features include:

  • Match Type buttons that set the match mode for the regular expression. The buttons represent functions that let you Match, Match All, Split, Replace and Replace All.
  • For Python regular expressions, there are two new modifiers: Unicode and Locale.

Multi-User Features

  • A Shared Toolbox with functionality similar to the standard Toolbox makes it possible for multiple users to share items such as run commands and code snippets. The Shared Toolbox is enabled via a check box on the Shared Support page of Komodo Preferences.
  • Users can accept a default Common Data Directory or specify a custom location via the new Shared Support page in Komodo Preferences.
  • Multiple users can share .tip, .pcx and .pdx files and preferences.

Enhanced Search Functionality

  • The new Open/Find Toolbar makes it easier to open files and search for strings in currently open files.
  • A Find in Files dialog box is used to search for files that are not currently open.

Macro Enhancements

  • A Macro Toolbar provides a quick and easy way to record, pause, play, stop and save macros.
  • Macros are no longer stored as separate files (as they were in 2.x). Because macro content is now included in a macro item, it is easier to share macros between multiple users.
  • The Properties dialog box for macros contains a window in which macros can be coded in either JavaScript or Python.
  • Triggers can be set so that macros execute as a result of specific Komodo events.
  • The documentation includes a macro API.

Custom Toolbars, Menus and Icons

Create Custom Toolbars and Menus for frequently used components. Custom Toolbars are displayed beneath the existing toolbars; custom menus are added to Komodo's top-level menu, between the Tools and Windows menus. Custom icons can be assigned to components like run commands, snippets, etc.

Editing Enhancements


  • PHP 5 is supported.
  • Support for Web services has been deprecated. Note that this will not prevent the use of Web services in applications developed in Komodo.
  • Users familiar with the Emacs editor can configure Komodo to use Emacs key bindings and set a File Associations preference so that Komodo checks for an embedded Emacs mode specification.
  • Support for Tcl has been improved to include more detailed logging and additional syntax checking options.
  • Two new interpolation shortcuts (%L and %P) can now be used in the Run Command dialog box.
  • Users now have the option to assign custom icons to Komodo components (snippets, run commands, etc).
  • Printing features for specifying line wrapping and font scaling have been added to the Printing page in Komodo Preferences. This page is now also accessible by clicking Print Settings on the File menu.
  • Components from Projects or the Toolbox can be exported to a self-contained archive for distribution to other users. The import and export wizards are invoked via the right-click context menu in the Project or Toolbox tab, or from the Toolbox menu.
  • Perl, Python and Tcl preferences include the ability to specify import directories.
  • On the Editor|Key Bindings preference page, the key bindings list can be filtered.


  • The new Feature Showcases are quick demos of Komodo features.
  • Komodo Help now displays in a selected web browser.
  • Improved search capabilities, including phrase search and result ranking, make it easier to locate specific information.
  • The documentation includes an index.
  • Context-sensitive Help buttons have been added throughout the Komodo workspace.
  • The documentation includes a macro API.

This release contains bug fixes for Komodo 2.5 and 2.5.1, including:

  • Intermittent crashes were occurring on Linux, caused by the autosave feature.
  • On Linux, the Internationalization dialog in Komodo's Preferences was generating an error.
  • Perl's Visual Package Manager was not always reporting a startup failure to the user.
  • AutoComplete for Perl and Python did not work.
  • Intermittently, the variable type indicator (i.e., $, @, %) was not being selected when double-clicking on a variable in the editor pane.
  • Umlaut characters were causing file contents to be lost on save.
  • CVS source code control integration functions were not available on directories or projects.
  • The Tcl statement source file was not finding the specified file.
  • There were errors in Tcl syntax checking.
  • CVS source code control integration was generating errors on Solaris.
  • There were debugging errors when working with Tcl scripts on Solaris.
  • When adding template items to a project or the Komodo Toolbox, it was not possible to cancel the file selection operation.
  • The CVS source code control integration now supports use of a local repository.
  • The update function in Komodo's source code control integration was not functioning under certain circumstances.
  • On Solaris, it was not possible to create a file on an NFS-mounted disk.
  • Regardless of the setting for line endings, new files were created with DOS/Windows line terminators.
  • Perl brace matching could cause Komodo to lock up under certain circumstances.
  • XML AutoComplete could cause Komodo to lock up.
  • During a workspace restoration, if multiple files contained breakpoints, the breakpoints were not being written to Komodo's breakpoint manager and would have to be manually re-set.
  • After debugging, debugger arrows were still active on files that had been stepped into.
  • Files names that included spaces could not be added to projects.
  • Under certain circumstances, Komodo would not start on Red Hat version 8.
  • Autosave functionality is now more robust.
  • Under certain circumstances, opening files resulted in a blank page in the editor pane.
  • On Linux, the debug session would occasionally hang due to problems with the remote debug listener.

Komodo 2.5.1 (October, 2003)

This release contained bug fixes for Komodo 2.5. The only user-visible changes were:

  • When clickable links are displayed in the Output Pane, you must double-click (rather than single click) to follow the link. This allows for portions of the link to be selected via single-clicks. The link is no longer underlined.
  • The default Perl remote debugging port has changed from 9010 to 9011 (due to a conflict with the XIM server on UNIX). To use the new port, alter the PERLDB_OPTS setting on the remote machine. If you are invoking the Komodo debugger via the Perl Dev Kit's -debug switch, ensure that the specified port number matches the Komodo's port number.
  • The menu link for the Start Page has been moved from the Help menu to the Windows menu.
  • The Close All menu option no longer closes the Start Page.
  • The Internationalization preference page for language encodings has changed. Programming-language specific encodings are now used for existing files, as well as new files.

The following major bugs were fixed:

  • The highlighting of selected text was not released if the mouse pointer moved outside of the editor pane.
  • Komodo Personal failed to start up properly if the Show Button Text option was enabled.
  • Background syntax checking would cease to function.
  • Saving of remote files failed for long editing sessions.
  • Remote debugging didn't honor Perl breakpoints.
  • The Rx window could hang.
  • Hotspots in the Output pane were generated for spurious lines and the dialog was hard to dismiss.
  • Installing web services for Perl 5.8 is fixed.
  • The Build Standalone Perl Application dialog didn't deal well with scripts with UNC filenames (\\machine\drive\...).
  • Printing collapsed whitespace in the middle of lines.
  • The ability to show diffs in an editor tab wasn't working.

Komodo 2.5 for Windows, Linux (September, 2003)


  • Komodo's speed has been boosted through re-engineering, resulting in quicker times for startup, tab-switching, loading of dialogs, as well as overall performance gains.
  • Menus have been re-organized, and new items have been added. Every Komodo feature can now be accessed through the top-level menus.
  • The Preferences pages and a number of existing dialogs have been improved and reorganized for ease-of-use. Changed dialogs include those associated with current file settings, templates, source code control, remote files, and the Perl Dev Kit.
  • Templates can now use the same interpolation shortcuts as commands and snippets. Prior to Komodo Version 2.5, a set of variables could be used to embed the current date and time in files created from custom templates. The old codes have been deprecated and will be removed in the next Komodo release.
  • The Show Unsaved Changes command, previously exclusive to the Editor context menu, has been added to the File menu.
  • A new Compare Files feature on the Tools menu provides a quick and easy way to locate and "diff" two files.
  • A Word Wrap command has been added to the View menu.
  • A Tcl tutorial has been added to Komodo's set of language tutorials. Another new tutorial, the Komodo Tour, provides an introduction to the program's key features.
  • ASPN Cookbook integration is no longer supported.


  • Changes have been made to make more efficient use of the Komodo workspace:
    • A Full Screen command has been added to the View menu.
    • The Toolbox and Project Manager, which previously appeared in separate panes, are now contained in single pane. You can select Projects/Toolbox Pane from the View menu to show or hide this pane.
    • Toolbar button text is not displayed by default. Hiding the button text makes it possible for the toolbars to share a single row.
  • The functionality of Komodo's ancillary windows has been enhanced. The Debug Output, Command Output, and SCC Output tabs in the Output Pane offer context menus with access to a subset of the top-level View menu. There are key bindings for each of the context menu items. The same context menu is available in the "diff" window, which is invoked by either the Show Unsaved Changes command or the Compare Files command. The ancillary windows also support "hot-spotting". If Komodo detects a file reference, it will create a hot spot that links to the file itself.
  • Interpreter errors displayed in the Output Pane are now hyperlinks to the relevant line.
  • 'Ctrl'+'Tab' functionality is now supported in all of the panes in the Komodo workspace. Earlier versions of Komodo supported tab-switching in the Editor Pane only.
  • The Output tab and the Variables tab are now known as the Debug Output tab and Debug Variables tab, respectively.
  • The "grippies" used to show and hide the panes in the Komodo workspace have been abandoned in favor of "x" close buttons.

Project Manager and Toolbox

  • The new Toolbox menu provides functionality for importing and exporting items, along with other commands that were previously exclusive to the Toolbox context menu. The Projects/Toolbox Pane contains the Projects tab and the Toolbox tab. You can show or hide the Projects and Toolbox tabs by pressing 'Ctrl'+'Shift'+'P' and 'Ctrl'+'Shift'+'T', respectively.


  • Additions to the Window menu offer new display options for the Editor Pane. Selecting Split View divides the Editor Pane in two, so that you can preview files (e.g., HTML or XML) or compare two files. Select Rotate Tab Groups to toggle vertical and horizontal variations of the split view.
  • The View As Language item on the View menu now has a submenu item called Reset to best guess. Select this item to ignore the user preference, and analyze the file in an attempt to determine its language.
  • Change the language of an open file by right-clicking the name of the language on the status bar and selecting a language from the pop-up menu.
  • A new Smart Editing preference gives you the choice of configuring the 'Tab' key instead of 'Ctrl'+'Space' to trigger Komodo's word-completion feature.
  • The Go To Line dialog box now supports entries that are relative to the current line. For example, instead of entering a specific line number, you can enter "+10" or "-10" to move ten lines forward or back.
  • There are some changes to the default key bindings. For a complete listing of default key bindings, select Help|List Key Bindings.
  • The Ignore Hidden Text option has been removed from the Find dialog box.
  • Komodo now supports editing with non-English characters, based on the locale specified in the regional settings for Windows. See Customizing International Encodings for more information.

Web and Browser

  • A Preview in Browser command is now available through the View menu and the main toolbar. Depending on how the Web and Browser preferences are configured, this command will display a preview in one of three ways:
    • in the Editor Pane
    • side-by-side with the source code in a split view of the Editor Pane
    • in a separate window

GUI Builder

  • GUI Builder functionality has been extended to include language-specific widget palettes that are displayed according to the initial language selection. In addition, a greater variety of widgets is available.
  • The new Dialog tab displays an interactive organizational map that makes it easier to plan and manage the structure of dialogs.
  • The new Menu tab is used to create drop-down menus. The Menu tab features an additional widget set used to create standard menu commands, as well as commands with check box or radiobutton behavior.


  • The new Page Setup options used to set orientation, margins, and headers and footers can now be accessed from the File menu.
  • A new Print Preview command has also been added to the File menu. In addition to navigation buttons for viewing multi-page print jobs, the preview window offers access to Page Setup options. As a result, printing preferences available in Komodo 2.3, including Print Line Wrap Markers, Characters per line and Font Size Adjustment, have been removed.
  • Selecting the Print to HTML command now opens the generated file.

Fonts and Colors

  • The Fonts and Colors preferences have been streamlined to make managing these settings easier. You can create new font and color schemes based on the default scheme.

  • A Run Without Debugging item has been added to the Debug menu, providing a faster way to run scripts in Komodo.
  • A new debugging preference, Try to find files on the local system when remote debugging, has been added. When this preference is turned on, Komodo will search for the debugger file on the local system instead of automatically opening a read-only version of the file retrieved from the debug engine.
  • Komodo now offers full support for Tcl debugging. In addition, runtime Tcl syntax checking no longer requires the Tcl Dev Kit.

Source Code Control

  • The Automatically check out before save option has been moved from "General Source Code Control Preferences" to "Perforce" Preferences, where it appears as Automatically open files for edit before save.

Komodo 1.1 (June, 2001)

PHP Debugging Enjoy PHP syntax checking and debugging with Komodo. You can configure Komodo to debug PHP files locally or within a Web server environment. For more information, see Debugging Programs in the Online Help.

XSLT Debugging - This release supports XSLT debugging. You can view your XSLT file, your XML input file, and your output simultaneously. You can even open an XML file on your Web server and transform the file while you debug your XSLT program. We've also improved the sample XSLT file in our Sample Project. For more information on XSLT debugging, see Debugging Programs in the Online Help.

Tcl support - You can now use Komodo to edit your Tcl files, including syntax coloring, code folding, AutoComplete and CallTips. We added a Tcl file to our Sample Project. If you have Tcl Dev Kit, you can enjoy Tcl syntax checking within Komodo. We plan to include stand-alone syntax checking that does not require Tcl Dev Kit in an upcoming release. Komodo does not yet support Tcl debugging.

Improved Performance - This release is based on the latest Mozilla tree, which includes an optimized code base. Performance improvements include faster installation and startup and faster response while you type or change files. Komodo responds much faster during debugging, when opening files and switching between files, and when loading the File Associations pane in the Preferences dialog.

Support for more languages - You can now use Komodo to edit Ruby and other languages, such as VB and SQL.

Improvements for Komodo on Linux - You can now resize the Komodo workspace, you can use fixed-width fonts, and you can debug Perl scripts if you have Perl 5.6 installed and configured.

XML AutoComplete - Komodo now features AutoComplete for your XML files. When you type an open angle-bracket "<", Komodo lists the elements in your file. Komodo XML AutoComplete also lists tag attributes and suggests attribute values for certain values. XML AutoComplete also helps you close your tags.

Expanded Find and Replace dialog - You can now use regular expressions in your find and replace strings, you can search through folded text, and more.

Partial Unicode support - Komodo supports ASCII, Latin-1 and Unicode (UTF-8, UCS-2 or UCS-4) encoding. If you use Komodo to edit a file that has a different character encoding than those mentioned above, non-English characters may be removed when you save the file.
