This is a simple reader/writer of Valve Data Format (a.k.a. KeyValues) written in ANSI C.
This library was made as a sort of an exercise in C, since I mainly use C++.
Hopefully no memory leaks! But if there still are, feel free to submit an issue or a pull request.
I tried making sure that all allocated memory was fully and properly freed before program termination.
See DOCUMENTATION.md file for more information.
- Character buffers may be null-terminated or limited to a maximum size.
- The files are parsed using
fopen()with"rb"and reading the contents into a character buffer. - The ability to create versatile contexts for reading data in a specific way, as well as functions for quick one-line parsing.
- Character buffers are created and expanded by the specified step size on the fly, without having to do it manually.
- The files are written using
fopen()with"w"in order to insert platform-specific line breaks.
- Keys and string values of any length.
- Support for CPP-styled single-line comments (
//) and C-styled block comments (/* */). - Context flags for toggling specific features:
- Support for escape sequences in strings (ON by default).
- Support for multiple values under the same key name (ON by default).
- Value replacement in duplicate keys, if multi-key support is disabled (ON by default).
- Case-insensitive
#base&#includemacro support that includes files from absolute paths or relative to the specified base directory.- The behavior of each inclusion macro is identical to Source SDK 2013.
- Context flags for multi-key support and value replacement in duplicate keys are ignored when merging pairs using
#basedue to its unique behavior.
- Conditional statements before the pairs, e.g.
[$WIN32] "key" "value". - Non-ASCII encodings.
- Include
keyvalues.cin your project or link the library in your CMake project usingCMakeLists.txt. - Include
keyvalues.hin your C/C++ code.
Sample code with usage examples can be found here.
