The standard used to represent the available values for each command is:
 
 
''FLOATS'' are represented with one decimal:
 
<code>0.0 .. 1.0</code> &rarr; all float values between 0 and 1 included
 
 
''INTEGERS'' are represented with numbers or descriptions:
 
<code>1 .. 5</code> &rarr; all integers between 1 and 5 included ( 1 , 2 , 3 , 4 , 5 ) <br>
<code>1 .. (MAX n layers)</code> &rarr; all the integers between 1 and the maximum index of layers in MXW (e.g. if 6 layers are being used the values are integers between 1 and 6 included)
 
When only one number is indicated it means that only one option is given. This is found in addresses of buttons, checkboxes and in the options where "0" or "1" are the only significant values


This page lists the commands of the MXWendler JavaScript command interface. Scripts run on an embedded ECMAScript engine (Duktape) and reach the software through the global <code>mxw</code> object plus a few free functions.


''STRINGS'' are represented between double quotation marks:
'''The presented JavaScript commands supported in version 7.2. and up'''
 
<code>/mxw/set info </code>
 
When <code>“name”</code> is contained in the available string variable, then the content is to be substituted with the actual name.
E.G. :  to select and play a patch called “patch_one” from its name, the address <code>/mxw/set</code> with tokens <code>"play" "name_of_patch"</code> has to be used, resulting in this OSC command:
 
<code>/mxw/set play patch_one</code>
 
 
When <u>OR</u> is found it means that two options can deliver a similar result. One of the two formats has to be used at one time.

This page lists the commands of the MXWendler JavaScript command interface. Scripts run on an embedded ECMAScript engine (Duktape) and reach the software through the global mxw object plus a few free functions.

The presented JavaScript commands supported in version 7.2. and up

Legend

FLOATS are written with one decimal: 0.0 .. 1.0 → every float between 0 and 1 inclusive.

INTEGERS are written as plain numbers or ranges: 1 .. 5 → the integers 1,2,3,4,5.

STRINGS are written between double quotes.

When OR appears, two alternative call formats produce a similar result; use one at a time.

Addressing: widgets are targeted by their OSC-style address string, e.g. /mxw/track/active/layer/active/clip.

Access model: mxw.playlist and mxw.io are ready-made objects – call their methods directly, e.g. mxw.playlist.play(), mxw.io.dmx(4). mxw.widget(address), mxw.media(name), mxw.preload(n) and mxw.grabber(name) are factories that take an address/name/index and return the object to call, e.g. mxw.widget("/mxw/path").getValue().
