Pre-Conditions
This tutorial is written explicitly for LiveCode 6.6.2 Stable and might not work with other versions. The tutorial will not be updated!
Namespace
LiveCode does currently not have anything like a namespace as found in in C or PHP. There are two different ways how you can handle this.
Possibility 1
ee = first and last letter of company name
Player = what the substack does
Example: eePlayerStart, eePlayerStop, eeDbGet, eeDbInsert
Possibility 2
Since a few month I've started with a new naming convention with dots.
ee = first and last letter of company name
player = what the stack/library does
playVideo = method name
Example:
- ee.player.playVideo
- ee.sql.insert
- ee.couchdb.createDocument
This naming convention does not clash with the Livecode engine. I've asked my Account Manager at Livecode and got positive feedback by the core team.
Variable Prefixes
The variable prefixes have been defined as best practice in the comprehensive manual that comes with LiveCode which you can find within the install directory.
| Prefix | Variable Type | Example |
|---|---|---|
| g | Global Variable | gMyVar |
| s | Script Local Variable | sMyVar |
| t | Handler Local Variable | tMyVar |
| p | Parameter | pMyVar |
| k | Constant | KMYVAR |
Tool Prefixes
These are my personal prefixes for the tool names.| Prefix | Variable Type | Example |
|---|---|---|
| btn | Button | btnSave |
| lbl | Label | lblName |
| fld | Text Field | fldName |
| chb | Check Box | chbName |
| cob | Combo Box | cobName |
| rdb | Radio Button | rdbName |
| lst | Scrolling List | lstName |
| mnu | Option Menu | mnuName |
| tab | Tab Panel | tabName |
| img | Image Area | imgName |
| tbl | Basic Table | tblName |
| dg | DataGrid | dgName |
LiveCode and OOP
With some small scripts you can turn your way of writing applications in LiveCode in to full OOP (object oriented programing).
This article explains the details.
