The above is all valid. However, using *.jpg or any other files saved in an image format is not possible.

Description

Description:
Reads and processes the content of the specified file. Preprocessor is C-like, supports comments using // or /* and */ and macros defined with #define.
Due to the hard-drive access this command executes (and the lack of caching) this command should not be used in time-critical script loops.

Syntax

Syntax:
String = preprocessFile fileName
Parameters:
fileName: String
Return Value:
String

Examples

Example 1:
_content=preprocessFile "myFunction.sqf"

File path is always relative to mission directory. If script dir\a.sqf includes dir\b.sqf, use "dir\b.sqf" and not "b.sqf".

Use preprocessFileLineNumbers instead as it provides more context information on error.

The main difference between preprocessFile and preprocessFileLineNumbers is that the latter adds #line directive to the target file, which allows to log the __LINE__ error happened at and the __FILE__ error happened in. PreprocessFile.jpg

Bottom Section


Essentially what the preprocessFile command does is it refers to the contents of a file as a string:
Example 1:
boop.html: <t align = 'center' valign = 'middle' shadow = '0' size = '2'>structured text</t> init.sqf: _text = parseText preprocessFile "boop.html"; hint _text;
This is especially useful for long strings, and it works on files with any file extension as long as they can be edited with a text editor.
Example 2:
init.sqf:
hint preprocessFile "description.ext"; copyToClipboard preprocessFile "mission.sqm"; The above is all valid. However, using *.jpg or any other files saved in an image format is not possible.
