Detailed Description

template<class SI_CHAR, class SI_STRLESS, class SI_CONVERTER>
class mrpt::config::simpleini::CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >

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.

private

Add the section/key/value to our data.

Parameters

a_pSection	Section name. Sections will be created if they don't already exist.
a_pKey	Key name. May be nullptr to create an empty section. Existing entries will be updated. New entries will be created.
a_pValue	Value for the key.

	)

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; there is no way to selectively delete individual key/values in this situation.

Parameters

a_pSection	Section to delete key from, or if a_pKey is nullptr, the section to remove.
a_pKey	Key to remove from the section. Set to nullptr to remove the entire section.
a_bRemoveEmpty	If the section is empty after this key has been deleted, should the empty section be removed?

		const SI_CHAR *	a_pDefault = `nullptr`,
		bool *	a_pHasMultiple = `nullptr`
	)		const

Retrieve the value for a specific key.

If multiple keys are enabled (see SetMultiKey) then only the first value associated with that key will be returned, see GetAllValues for getting all values with multikey.

NOTE! The returned value is a pointer to string data stored in memory owned by CSimpleIni. Ensure that the CSimpleIni object is not destroyed or Reset while you are using this pointer!

SI_Error mrpt::config::simpleini::CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >::Save ( OutputWriter & a_oOutput ) 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, etc from the original data are not preserved. Only valid data contents stored in the file are written out. 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.

Parameters

a_oOutput Output writer to write the data to.

Returns: SI_Error See error definitions

◆ SetMultiKey()

void mrpt::config::simpleini::CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >::SetMultiKey ( bool a_bAllowMultiKey = true )

inline

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.

Parameters

a_bAllowMultiKey Allow multi-keys in the source?

void mrpt::config::simpleini::CSimpleIniTempl< SI_CHAR, SI_STRLESS, SI_CONVERTER >::SetMultiLine ( bool a_bAllowMultiLine = true )

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.

Parameters

a_bAllowMultiLine Allow multi-line values in the source?

		const SI_CHAR *	a_pKey,
		const SI_CHAR *	a_pValue,
		const SI_CHAR *	a_pComment = `nullptr`
	)

inline

Add or update a section or value.

This will always insert when multiple keys are enabled.

Parameters

a_pSection	Section to add or update
a_pKey	Key to add or update. Set to nullptr to create an empty section.
a_pValue	Value to set. Set to nullptr to create an empty section.
a_pComment	Comment to be associated with the section or the key. If a_pKey is nullptr 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).

Returns: SI_Error See error definitions; SI_UPDATED Value was updated; SI_INSERTED Value was inserted
