Demonstrates how to implement #include with a Chilkat StringBuilder.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# First build a string that has a preprocessor include
sbSrc = Chilkat::CkStringBuilder.new()
sbSrc.Append("1\r\n2\r\n3\r\n")
sbSrc.Append("#include <qa_data/txt/helloWorld.txt>\r\n")
sbSrc.Append("4\r\n5\r\n")

print sbSrc.getAsString() + "\n";

# sbSrc contains:
# 	1
# 	2
# 	3
# 	#include <qa_data/txt/helloWorld.txt>
# 	4
# 	5

# The qa_data/txt/helloWorld.txt file contains "Hello World!"

filePath = sbSrc.getAfterBetween("#include","<",">")
if (sbSrc.get_LastMethodSuccess() != true)
    print "No #include's found." + "\n";
    exit
end

print "filePath: " + filePath + "\n";

# Load the contents of the filePath
sbIncludeFile = Chilkat::CkStringBuilder.new()
sbIncludeFile.LoadFile(filePath,"utf-8")

# Replace the first occurrence of #include <...> line with the contents of the include file.
sbSrc.ReplaceAllBetween("#include",">",sbIncludeFile.getAsString(),true)

print sbSrc.getAsString() + "\n";

# sbSrce now contains:
# 	1
# 	2
# 	3
# 	Hello World!
# 	4
# 	5
