![]() This obviously covered syntax coloring, but we wanted to include auto-indenting, code-folding, selection-commenting, and as much as possible, code-completion. We wanted to make this a Komodo extension point, so someone using a language like Liquid 1 would be able to add an extension to Komodo, and take advantage of as many language-aware features in Komodo as possible. The other problem with either of those two approaches was that they both entailed a rebuild of Komodo, which meant that a new feature wouldn’t be available until the next release. Some of them even have their own little language on top of the SSL - Perl’s Template-Toolkit and Smarty/PHP are two common examples. And they all have transition points that indicate when to move from HTML to the SSL, and when to return. ![]() They usually embed a “server-side language” (“SSL” for short) - this is the code that is run on the server, emitting the HTML at run-time. If they’re (X)HTML-based, they should support embedded CSS and JavaScript. They all have a markup base, which we could safely assume to be XML, XHTML, or HTML. Meanwhile, most template languages also have many common features. Each template language can have a few idiosyncracies, and it’s important to handle them correctly to create a smooth editing experience. Template languages can be complex, with many edge cases that we wanted to handle well. make a modification to the HTML/PHP lexer (it currently also has some support for ASP, VBScript, and Embedded Python), and associate new languages with it. ![]() Previously, we had two options to support new languages: They’re invoked on almost every keystroke, and they try to update the style of each visible character as quickly as possible. These lexers are important parts of Komodo. Now we knew that the Scintilla HTML/PHP lexer wouldn’t be satisfactory for all these other template languages. ![]() Communities of avid fans will grow around them, and some of them will be looking for a GUI-type editor to manage them in. So we envision that increasingly more template languages will be created. Replace the eval() statement with pattern-matching and a managed symbol table, and you have something other people can use. If the language can be freely embeddable in a web server like Apache, so much the better. Put together an XML or HTML parser, maybe an XPath processor, and a language that has an eval() statement, and you have an instant template language (if one that is inherently insecure, with that eval statement. These template languages are relatively easy to build. During the last couple of years we’ve seen near-instant uptake of emerging high-level frameworks like Rails, Django, and CakePHP. But over the years we saw new multi-component languages get released, and enthusiastic users discovering that this was exactly what they needed to deliver dynamic web content quickly. The editor Komodo is based on, Scintilla, actually bundles HTML and PHP processing in the same colorizing module. When we started work on Komodo, around 2000, PHP was the only commonly-used open template language (“open” allows me to leave proprietary systems like JSP, ASP, and ColdFusion out of the discussion). The concept is still new enough that there is no universal agreement on a name for the nature of the contents of these glue files, but “template languages” seems to be the most common. Usually you need a few files to glue together the various pieces. Tasks are broken down into separate files, so the programmers can work on code, the writers in HTML or XML, and the designers with CSS. It’s well-understood that a template-based system is a better way of delivering web content than writing pure code. $ tar xfz komodo-installdir/lib/support/luddite/ Copy the kid.zip file into that directory, and unzip it by running unzip -a kid.zip.įor those who prefer shell commands: $ mkdir -p ~/play # scratch directory The first zip/tgz file creates a directory called “luddite-1.0.0”. Then download kid.zip, which contains a final version of the files this tutorial walks you through. Unpack the zip or tar file into a work area outside the Komodo install area, since we’ll be reusing many of the files we ship, or making slight modifications to them. You’ll find the first one in your Komodo install area, at /lib/support/luddite/luddite.zip (Windows), /lib/support/luddite/ (Linux), or. This tutorial works best with two zip files. We’re working on getting it operational again. The API changed slightly when 4.2 was released, but wasn’t quite correct. This Tutorial doesn’t work with Komodo 4.2 Kid: Adding a New Language to Komodo with UDL
