Debug and log utilities
Build-in global variable console is a great way to debug application and log information. Text sent to console can be viewed in IDE Console pane (docked in the bottom-left side of IDE).
There are some build-in global functions and statements that provide additional debug information. All script objects have function show(), which displays a list of functions, properties and their values.
Note: Only script objects provide show(), there is no such method for native objects, or it exists in a different way for this purpose (e.g. Dialog.show() shows the UI dialog). See example:
var obj = {
firstName: "Jozef",
nickName: "Oxy",
age: 33
}; obj.show();
displays
Class Object: [object Class]
Properties:
age: 33
nickName: "Oxy"
firstName: "Jozef"
In the framework, there is a set of functions designed to work with IDE and logs information of several severity levels. To access this feature you need to include “lib://core/log.ms” file.
- logI(); - Logs debug string with severity I - Information to Moscrif - IDE console
- logW(); - Logs debug string with severity W - Warning to Moscrif -IDE console
- logE(); - Logs debug string with severity E -Error to Moscrif -IDE console
- log(); - Logs debug string without any severity
include "lib://core/log.ms"; var i = 10;
var pt = {x: 10, y: 20};
var str = "Hello"; logI(i, str);
logW(String.printf("Warning: pt=%V", pt));
logE("File not found!"); log(i, pt, str);
Shows following text in the Console pane:
Log-I: 07:42.475 10 Hello Log-W: 07:42.476 Warning: pt={y:20,x:10} Log-E: 07:42.476 File not found! Log-I: 07:42.476 10,[object Object],Hello
