Text editor running on your ARM project

bare-metal-elua-text-editor

Tired of flashing your embedded project over and over just to tweak a few values? So was [Karl], so he wrote a text editor that runs on his ARM dev board.

Having trouble wrapping your mind around the need for this kind of thing? He’s actually playing around with eLua, the embedded version of the Lua programming language. In this case the program files are being stored on an SD card. But still, moving that back and forth between computer and embedded project gets old quickly. So he invested the time to write a rudimentary text editor that he interfaces through this terminal window. Above you can see the help screen which lays out all of the applications features. Right now it sounds like the only gotcha for this is the amount of RAM it needs to run. As it stands, the editor will now work an mbed board, but it works just fine on an STM Discovery.

Javascript Vi


Few would dispute that Vi was a great text editor in its day, but no one has done anything to bring it back until now. A company called Internet Connection has developed JSVI, a clone of Vi that was written in javascript and runs inside editable text areas on virtually any browser with javascript support.

It functions identically to Vi, offering ed/ex command support, vi-keys, unicode awareness, and a number of other features available on Vi. You can see a demo of JSVI here. If you prefer to run vi on your own page, download this javascript document. JSVI is open source, and we certainly agree with [Jason Striegel] that this would make a fitting addition to any Unix blog or forum.

emacs sucks.

Free web development tools


OStatic has a collected some great free tools for web developers. We talked about Quanta in an earlier post, but this article reaches beyond just HTML editors. LaunchSplash can be used to generate splash pages while you build. IBM, responsible for the Eclipse IDE, has built Project Zero to encourage web app development; even the IDE is web based. OpenX is an open ad server. Piwik is a free web analytics package. There are also quite a few open source CMS’s and sites collecting open source designs.
