Jump to the @link CSimpleIniTempl CSimpleIni @endlink interface documentation. @section intro INTRODUCTION This component allows an INI-style configuration file to be used on both Windows and Linux/Unix. It is fast, simple and source code using this component will compile unchanged on either OS. @section features FEATURES - MIT Licence allows free use in all software (including GPL and commercial) - multi-platform (Windows CE/9x/NT..10/etc, Linux, MacOSX, Unix) - loading and saving of INI-style configuration files - configuration files can have any newline format on all platforms - liberal acceptance of file format - key/values with no section - removal of whitespace around sections, keys and values - support for multi-line values (values with embedded newline characters) - optional support for multiple keys with the same name - optional case-insensitive sections and keys (for ASCII characters only) - saves files with sections and keys in the same order as they were loaded - preserves comments on the file, section and keys where possible. - supports both char or wchar_t programming interfaces - supports both MBCS (system locale) and UTF-8 file encodings - system locale does not need to be UTF-8 on Linux/Unix to load UTF-8 file - support for non-ASCII characters in section, keys, values and comments - support for non-standard character types or file encodings via user-written converter classes - support for adding/modifying values programmatically - compiles cleanly in the following compilers: - Windows/VC6 (warning level 3) - Windows/VC.NET 2003 (warning level 4) - Windows/VC 2005 (warning level 4) - Linux/gcc (-Wall) @section usage USAGE SUMMARY -# Define the appropriate symbol for the converter you wish to use and include the SimpleIni.h header file. If no specific converter is defined then the default converter is used. The default conversion mode uses SI_CONVERT_WIN32 on Windows and SI_CONVERT_GENERIC on all other platforms. If you are using ICU then SI_CONVERT_ICU is supported on all platforms. -# Declare an instance the appropriate class. Note that the following definitions are just shortcuts for commonly used types. Other types (PRUnichar, unsigned short, unsigned char) are also possible.
Interface Case-sensitive Load UTF-8 Load MBCS Typedef
SI_CONVERT_GENERIC
char No Yes Yes #1 CSimpleIniA
char Yes Yes Yes CSimpleIniCaseA
wchar_t No Yes Yes CSimpleIniW
wchar_t Yes Yes Yes CSimpleIniCaseW
SI_CONVERT_WIN32
char No No #2 Yes CSimpleIniA
char Yes Yes Yes CSimpleIniCaseA
wchar_t No Yes Yes CSimpleIniW
wchar_t Yes Yes Yes CSimpleIniCaseW
SI_CONVERT_ICU
char No Yes Yes CSimpleIniA
char Yes Yes Yes CSimpleIniCaseA
UChar No Yes Yes CSimpleIniW
UChar Yes Yes Yes CSimpleIniCaseW
#1 On Windows you are better to use CSimpleIniA with SI_CONVERT_WIN32.
#2 Only affects Windows. On Windows this uses MBCS functions and so may fold case incorrectly leading to uncertain results. -# Call LoadData() or LoadFile() to load and parse the INI configuration file -# Access and modify the data of the file using the following functions
GetAllSections Return all section names
GetAllKeys Return all key names within a section
GetAllValues Return all values within a section & key
GetSection Return all key names and values in a section
GetSectionSize Return the number of keys in a section
GetValue Return a value for a section & key
SetValue Add or update a value for a section & key
Delete Remove a section, or a key from a section
-# Call Save() or SaveFile() to save the INI configuration data @section iostreams IO STREAMS SimpleIni supports reading from and writing to STL IO streams. Enable this by defining SI_SUPPORT_IOSTREAMS before including the SimpleIni.h header file. Ensure that if the streams are backed by a file (e.g. ifstream or ofstream) then the flag ios_base::binary has been used when the file was opened. @section multiline MULTI-LINE VALUES Values that span multiple lines are created using the following format.
        key = <<

    Note the following:
    - The text used for ENDTAG can be anything and is used to find
      where the multi-line text ends.
    - The newline after ENDTAG in the start tag, and the newline
      before ENDTAG in the end tag is not included in the data value.
    - The ending tag must be on it's own line with no whitespace before
      or after it.
    - The multi-line value is modified at load so that each line in the value
      is delimited by a single '\\n' character on all platforms. At save time
      it will be converted into the newline format used by the current
      platform.

    @section comments COMMENTS

    Comments are preserved in the file within the following restrictions:
    - Every file may have a single "file comment". It must start with the
      first character in the file, and will end with the first non-comment
      line in the file.
    - Every section may have a single "section comment". It will start
      with the first comment line following the file comment, or the last
      data entry. It ends at the beginning of the section.
    - Every key may have a single "key comment". This comment will start
      with the first comment line following the section start, or the file
      comment if there is no section name.
    - Comments are set at the time that the file, section or key is first
      created. The only way to modify a comment on a section or a key is to
      delete that entry and recreate it with the new comment. There is no
      way to change the file comment.

    @section save SAVE ORDER

    The sections and keys are written out in the same order as they were
    read in from the file. Sections and keys added to the data after the
    file has been loaded will be added to the end of the file when it is
    written. There is no way to specify the location of a section or key
    other than in first-created, first-saved order.

    @section notes NOTES

    - To load UTF-8 data on Windows 95, you need to use Microsoft Layer for
      Unicode, or SI_CONVERT_GENERIC, or SI_CONVERT_ICU.
    - When using SI_CONVERT_GENERIC, ConvertUTF.c must be compiled and linked.
    - When using SI_CONVERT_ICU, ICU header files must be on the include
      path and icuuc.lib must be linked in.
    - To load a UTF-8 file on Windows AND expose it with SI_CHAR == char,
      you should use SI_CONVERT_GENERIC.
    - The collation (sorting) order used for sections and keys returned from
      iterators is NOT DEFINED. If collation order of the text is important
      then it should be done yourself by either supplying a replacement
      SI_STRLESS class, or by sorting the strings external to this library.
    - Usage of the  header on Windows can be disabled by defining
      SI_NO_MBCS. This is defined automatically on Windows CE platforms.
    - Not thread-safe so manage your own locking
