Simple INI file reader.
This can be instantiated with the choice of unicode or native characterset, and case sensitive or insensitive comparisons of section and key names. The supported combinations are pre-defined with the following typedefs:
| Interface | Case-sensitive | Typedef |
|---|---|---|
| char | No | CSimpleIniA |
| char | Yes | CSimpleIniCaseA |
| wchar_t | No | CSimpleIniW |
| wchar_t | Yes | CSimpleIniCaseW |
Note that using other types for the SI_CHAR is supported. For instance, unsigned char, unsigned short, etc. Note that where the alternative type is a different size to char/wchar_t you may need to supply new helper classes for SI_STRLESS and SI_CONVERTER.

Delete an entire section, or a key from a section. Note that the data returned by GetSection is invalid and must not be used after anything has been deleted from that section using this method. Note when multiple keys is enabled, this will delete all keys with that name; to selectively delete individual key/values, use DeleteValue.

Delete an entire section, or a key from a section. If value is provided, only remove keys with the value. Note that the data returned by GetSection is invalid and must not be used after anything has been deleted from that section using this method. Note when multiple keys is enabled, all keys with the value will be deleted.

| SI_Error CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >::Save | ( | OutputWriter & | a_oOutput, |
| bool | a_bAddSignature = false |
||
| ) | const |
Save the INI data. The data will be written to the output device in a format appropriate to the current data, selected by:
| SI_CHAR | FORMAT |
|---|---|
| char | same format as when loaded (MBCS or UTF-8) |
| wchar_t | UTF-8 |
| other | UTF-8 |
Note that comments from the original data is preserved as per the documentation on comments. The order of the sections and values from the original file will be preserved.
Any data prepended or appended to the output device must use the the same format (MBCS or UTF-8). You may use the GetConverter() method to convert text to the correct format regardless of the output format being used by SimpleIni.
To add a BOM to UTF-8 data, write it out manually at the very beginning like is done in SaveFile when a_bUseBOM is true.
| a_oOutput | Output writer to write the data to. |
| a_bAddSignature | Prepend the UTF-8 BOM if the output data is in UTF-8 format. If it is not UTF-8 then this value is ignored. Do not set this to true if anything has already been written to the OutputWriter. |

inline |
Append the INI data to a string. See Save() for details.
| a_sBuffer | String to have the INI data appended to. |
| a_bAddSignature | Prepend the UTF-8 BOM if the output data is in UTF-8 format. If it is not UTF-8 then this value is ignored. Do not set this to true if anything has already been written to the string. |
| SI_Error CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >::SaveFile | ( | const char * | a_pszFile, |

When reading/writing an ini file, do we require every key to have an equals sign to delineate a valid key value. If false, then every valid key must have an equals sign and any lines without an equals sign is ignored. If true then keys do not require an equals sign to be considered a key. Note that this means that any non-commented line of text would become a key.
| a_bAllowKeyOnly | Permit keys without an equals sign or value. |

| a_bValue | Value to set. |
| a_pComment | Comment to be associated with the key. See the notes on SetValue() for comments. |
| a_bForceReplace | Should all existing values in a multi-key INI file be replaced with this entry. This option has no effect if not using multi-key files. The difference between Delete/SetBoolValue and SetBoolValue with a_bForceReplace = true, is that the load order and comment will be preserved this way. |

Add or update a numeric value. This will always insert when multiple keys are enabled.
| a_pSection | Section to add or update |
| a_pKey | Key to add or update. |
| a_nValue | Value to set. |
| a_pComment | Comment to be associated with the key. See the notes on SetValue() for comments. |
| a_bUseHex | By default the value will be written to the file in decimal format. Set this to true to write it as hexadecimal. |
| a_bForceReplace | Should all existing values in a multi-key INI file be replaced with this entry. This option has no effect if not using multi-key files. The difference between Delete/SetLongValue and SetLongValue with a_bForceReplace = true, is that the load order and comment will be preserved this way. |

Should multiple identical keys be permitted in the file. If set to false then the last value encountered will be used as the value of the key. If set to true, then all values will be available to be queried. For example, with the following input:
[section] test=value1 test=value2
Then with SetMultiKey(true), both of the values "value1" and "value2" will be returned for the key test. If SetMultiKey(false) is used, then the value for "test" will only be "value2". This value may be changed at any time.
| a_bAllowMultiKey | Allow multi-keys in the source? |
|
inline |
Should data values be permitted to span multiple lines in the file. If set to false then the multi-line construct <<<TAG as a value will be returned as is instead of loading the data. This value may be changed at any time.
| a_bAllowMultiLine | Allow multi-line values in the source? |
|
inline |
Should we recognise and parse quotes in single line values?
| a_bParseQuotes | Parse quoted data in values? |
|
inline |
Should spaces be added around the equals sign when writing key/value pairs out. When true, the result will be "key = value". When false, the result will be "key=value". This value may be changed at any time.
| a_bSpaces | Add spaces around the equals sign? |
|
inline |
Set the storage format of the INI data. This affects both the loading and saving of the INI data using all of the Load/Save API functions. This value cannot be changed after any INI data has been loaded.
If the file is not set to Unicode (UTF-8), then the data encoding is assumed to be the OS native encoding. This encoding is the system locale on Linux/Unix and the legacy MBCS encoding on Windows NT/2K/XP. If the storage format is set to Unicode then the file will be loaded as UTF-8 encoded data regardless of the native file encoding. If SI_CHAR == char then all of the char* parameters take and return UTF-8 encoded data regardless of the system locale.
| a_bIsUtf8 | Assume UTF-8 encoding for the source? |

Add or update a section or value. This will always insert when multiple keys are enabled.
| a_pSection | Section to add or update |
| a_pKey | Key to add or update. Set to NULL to create an empty section. |
| a_pValue | Value to set. Set to NULL to create an empty section. |
| a_pComment | Comment to be associated with the section or the key. If a_pKey is NULL then it will be associated with the section, otherwise the key. Note that a comment may be set ONLY when the section or key is first created (i.e. when this function returns the value SI_INSERTED). If you wish to create a section with a comment then you need to create the section separately to the key. The comment string must be in full comment form already (have a comment character starting every line). |
| a_bForceReplace | Should all existing values in a multi-key INI file be replaced with this entry. This option has no effect if not using multi-key files. The difference between Delete/SetValue and SetValue with a_bForceReplace = true, is that the load order and comment will be preserved this way. |
