CHAPTER 8: ExtendScript Tools and Features Preprocessor directives 234

#include file

Includes a JavaScript source file from another location. Inserts the contents of the

named file into this file at the location of this statement. The

file argument is an

Adobe portable file specification. See Specifying paths

As a convention, use the file extension

.jsxinc for JavaScript include files. For

example:

#include "../include/lib.jsxinc"

To set one or more paths for the #include statement to scan, use the #includepath

preprocessor directive.

If the file to be included cannot be found, ExtendScript throws a run-time error.

Included source code is not shown in the debugger, so you cannot set breakpoints

in it.

#includepath

path

One or more paths that the #include statement should use to locate the files to be

included. The semicolon (

;) separates path names.

If a

#include file name starts with a slash (/), it is an absolute path name, and the

include paths are ignored. Otherwise, ExtendScript attempts to find the file by

prefixing the file with each path set by the

#includepath statement.

For example:

#includepath "include;../include"

#include "file.jsxinc"

Multiple #includepath statements are allowed; the list of paths changes each time

#includepath statement is executed.

As a fallback, ExtendScript also uses the contents of the environment variable

JSINCLUDE as a list of include paths.

Some engines can have a predefined set of include paths. If so, the path provided by

#includepath is tried before the predefined paths. If, for example, the engine has a

predefined path set to

predef;predef/include, the preceding example causes the

following lookup sequence:

file.jsxinc literal lookup

include/file.jsxinc first #includepath path

../include/file.jsxinc second #includepath path

predef/file.jsxinc first predefined engine path

predef/include/file.jsxinc second predefined engine path

#script name

Names a script. Enclosing quotes are optional, but required for names that include

spaces or special characters. For example:

#script SetupPalette

#script "Load image file"

The name value is displayed in the Toolkit Editor tab. An unnamed script is assigned a

unique name generated from a number.

#strict on

Turns on strict error checking. See the Dollar ($) object’s strict property.
