sbini

A basic ini file parsing library that aims to be lightweight and easy to integrate. It relies only on the standard C library and uses some C99 functionality for safety.

Features

• Read and/or write ini files.
• Easy integration, simply drop in one header and one source file, and you're set!

Limitations

• No UTF8 support (ANSI only)
• Comments are limited to full line, end of line comments not supported.
• When reading and subsequently saving, any comments within the ini file are lost. (Refer to Issue #4)
• Some baffling decisions may have been made due to lack of sleep.

License

It's public domain under terms of the Unlicense. Refer to the bottom of the header and source files to read terms.

Basic Usage

test.ini

[test_group]
test1 = "this is a thing that can happen"
test2 = false
test4 = 3

[test_group_2]
test1 = 12.123123142
test2 = true
test3 = "This is a string that seems to go on for quite a while. Stay a while and listen, while I tell you about the majestic moose."
test4 = 0.0000123

    sbini_set_string(ini, "newly_added", "bass", "Rickenbacker 4003!");

    sbini_free(ini);

output.ini

[test_group]
test1 = "this is a thing that can happen"
test2 = false
test4 = 3

[test_group_2]
test1 = 12.123123123
test2 = true
test3 = "This is a string that seems to go on for quite a while. Stay a while and listen, while I tell you about the majestic moose."
test4 = 0.0000123

[newly_added]
testkey = true
anotherkey = 123.123398
whatisthis = 4003
bass = "Rickenbacker 4003!"

Program Output:

String: this is a thing that can happen
Integer: 3
Float: 12.123123
Boolean: 1
