IniFile Class Reference

Detailed Description

A utility to read and write configuration files in INI format.

On destruction, if there was any variable added or modified the file is automatically saved. When reading a variable name it is considered a "section/name" pair.

Example:

[main]
color = white
 
[network]
num_retries = 3

Can be read and written with:

IniFile config("settings.ini");
int num_retries = config["network/num_retries"];
config.set("main/color", "black");

The file in that example will be saved if the original color in section main was not "black".

The file can be cheked for correct reading and whether a variable exists:

IniFile config("settings.ini");
if(!config.ok()) {
    printf("Error reading %s\n", *config.fileName());
    return;
}
int num_retries = 5;
if(config.has("network/num_retries"))
    num_retries = config["network/num_retries"];

That last part can also be written as:

int num_retries = config["network/num_retries"] | 5;

Public Member Functions
	IniFile (const String &path, bool shouldwrite=true)
	Opens an INI file from the given path.
	~IniFile ()
	Destroys the object and save the file if there were modifications.
bool	ok () const
	Returns true if the file was read correctly.
const String &	fileName () const
	Returns the file name of this IniFile.
String &	operator[] (const String &name)
	Returns the value associated with the key name in the current section if the name is like section/name then the given section is used.
void	set (const String &name, const String &value)
	Sets the value for a key like 'section/name'.
const String	operator() (const String &name, const String &defaultVal) const
	Returns the value associated with the key name or defaultVal if it was not found.
void	write (const String &fname="")
	Writes the file with its modifications; this is done automatically on destruction, just call this if you need the file written before the object is detroyed.
Section &	section (const String &name)
	Sets the current section to 'name' (variables will be read from here by default)
bool	has (const String &name) const
	Returns true if the file contains a key named name.
int	arraysize (const String &name) const
	Returns the length of an "array" named name as written by the Qt library and enables reading its values.
String	array (const String &field, int index) const
	Returns the value associated with field name at the array position index of the array last specified with arraysize().
Array< String >	sectionNames () const
	Returns the names of sections in the file.
Dic	values () const
	Returns all keys and values as a map with keys as "section/key".
Dic	values (const String &secname) const
	Returns a section's keys and values as a map.

Member Function Documentation

array()

String array	(	const String &	field,
		int	index
	)		const

Returns the value associated with field name at the array position index of the array last specified with arraysize().

Deprecated:

Use ini[name/index\field]

arraysize()

int arraysize

(

const String &

name

)

const

Returns the length of an "array" named name as written by the Qt library and enables reading its values.

Deprecated:

Use ini[name/size]

has()

bool has

(

const String &

name

)

const

Returns true if the file contains a key named name.

If the name is like section/name then function tests a variable name in section section.

operator[]()

String & operator[]

(

const String &

name

)

Returns the value associated with the key name in the current section if the name is like section/name then the given section is used.

In the future this might return a const ref, so that modifications must be made with .set(k, v)

section()

Section & section

(

const String &

name

)

Sets the current section to 'name' (variables will be read from here by default)

Deprecated:

Use full names like "section/key"
