Include
The Include function inserts an additional
script file, or "chunk", into a script file. The external chunk is
compiled and executed when the Include
statement is executed. Any chunk may Include other
chunks.
Syntax
Include( sPath )
sPath is the absolute or relative
path of the file to be included (see Absolute
and Relative Paths, below).
On success,
the included chunk is executed and the script continues.
On failure,
such as a nonexistent file, the script shows a message and
exits.
Remarks
Most scripts need to load classes to work with
images, plots, files, and so forth. Mira includes its collection of
classes in compiled form. If you need to include other class
definitions, use the Include function in the chunk that uses the
class. For example, suppose you have created a class named
CMyClass and want to use it in a chunk. You have two choices
for making the class available to the script chunk: 1) include the
entire class's source code in the chunk where it is used, or 2)
define the class in its own file and then Include that file
in the chunk where CMyClass is needed. In this example, suppose you
saved the class definition file in [Mira]\Scripts\Classes\CMyClass.lua. Then you would
use the following syntax to include the class definition in a
chunk:
Include("Classes\\CMyClass.lua")
Note that, as in the C language, a double backslash
\\ is always needed in a literal
string unless you want the character following to be interpreted as
an escape sequence—regardless of whether it actually does form a
legal escape sequence. For example,\\t results in a backslash \ plus the letter t, whereas \t results in a tab character being imbedded
into the string.
Several useful functions are provided as script
chunks with the Mira Pro Script Module. These are located in
the folder [Mira]\Scripts\Include. To
access any of these functions from a script chunk, you need to use
the Include functions. For example, to include the function in the
file LoadImages.lua, place the
following statement in your script anywhere before the first use of
the LoadImages() function:
Include("Include\\LoadImages.lua")
Absolute and Relative Paths
The above example uses a relative path which
begins at the level of the Scripts subfolder inside the Mira
installation. If no machine name or drive is specified, Mira
interprets sPath as descending from the
[Mira]\Scripts folder.
Alternatively, you can specify sPath as
an absolute path that contains the drive letter, such as
C:. Using an absolute path
allows the included file to be located anywhere in the file
system.
