Diet Coda: Visual Tour Of An iPad Code Editor
Diet Coda's keyboard adds several keys to the visual keyboard that are very important to programmers such as Undo, indent, and left-and-right cursor movement keys. When in the mode to work with PHP code, it also displays additional keys such as "//" (line comment), ";", and "$" that are specifically useful for PHP coding. This eliminates the need to switch to the symbols plus numerals key view, which is extremely important to maintain coding rhythm. The app also provides support for storing blocks of code in clips. Several are predefined for the PHP code mode.
Important note: The green check button in the upper right of the display saves your current editing session to the remote server.
