Function Documentation

QString KMacroExpander::expandMacros	(	const QString &	str,
		const QHash< QChar, QString > &	map,
		QChar	c = QLatin1Char('%')
	)

Perform safe macro expansion (substitution) on a string.

The escape char must be quoted with itself to obtain its literal representation in the resulting string.

Parameters

str	The string to expand
map	map with substitutions
c	escape char indicating start of macro, or QChar::null if none

Returns

the string with all valid macros expanded

// Code example
QHash<QChar,QString> map;
map.insert('u', "/tmp/myfile.txt");
map.insert('n', "My File");
QString s = "%% Title: %u:%n";
s = KMacroExpander::expandMacros(s, map);
// s is now "% Title: /tmp/myfile.txt:My File";

QString KMacroExpander::expandMacros	(	const QString &	str,
		const QHash< QString, QString > &	map,
		QChar	c = QLatin1Char('%')
	)

Perform safe macro expansion (substitution) on a string.

The escape char must be quoted with itself to obtain its literal representation in the resulting string. Macro names can consist of chars in the range [A-Za-z0-9_]; use braces to delimit macros from following words starting with these chars, or to use other chars for macro names.

Parameters

str	The string to expand
map	map with substitutions
c	escape char indicating start of macro, or QChar::null if none

Returns

the string with all valid macros expanded

// Code example
QHash<QString,QString> map;
map.insert("url", "/tmp/myfile.txt");
map.insert("name", "My File");
QString s = "Title: %{url}-%name";
s = KMacroExpander::expandMacros(s, map);
// s is now "Title: /tmp/myfile.txt-My File";

QString KMacroExpander::expandMacros	(	const QString &	ostr,
		const QHash< QChar, QStringList > &	map,
		QChar	c
	)

Same as above, except that the macros expand to string lists that are simply join(" ")ed together.

QString KMacroExpander::expandMacrosShellQuote	(	const QString &	str,
		const QHash< QChar, QString > &	map,
		QChar	c = QLatin1Char('%')
	)

Perform safe macro expansion (substitution) on a string for use in shell commands.

The escape char must be quoted with itself to obtain its literal representation in the resulting string.

Parameters

str	The string to expand
map	map with substitutions
c	escape char indicating start of macro, or QChar::null if none

Returns

the string with all valid macros expanded, or a null string if a shell syntax error was detected in the command

// Code example
QHash<QChar,QString> map;
map.insert('u', "/tmp/myfile.txt");
map.insert('n', "My File");
QString s = "kedit --caption %n %u";
s = KMacroExpander::expandMacrosShellQuote(s, map);
// s is now "kedit --caption 'My File' '/tmp/myfile.txt'";
system(QFile::encodeName(s));

QString KMacroExpander::expandMacrosShellQuote	(	const QString &	str,
		const QHash< QString, QString > &	map,
		QChar	c = QLatin1Char('%')
	)

Perform safe macro expansion (substitution) on a string for use in shell commands.

See KMacroExpanderBase::expandMacrosShellQuote() for the exact semantics. The escape char must be quoted with itself to obtain its literal representation in the resulting string. Macro names can consist of chars in the range [A-Za-z0-9_]; use braces to delimit macros from following words starting with these chars, or to use other chars for macro names.

Parameters

str	The string to expand
map	map with substitutions
c	escape char indicating start of macro, or QChar::null if none

Returns

the string with all valid macros expanded, or a null string if a shell syntax error was detected in the command

// Code example
QHash<QString,QString> map;
map.insert("url", "/tmp/myfile.txt");
map.insert("name", "My File");
QString s = "kedit --caption %name %{url}";
s = KMacroExpander::expandMacrosShellQuote(s, map);
// s is now "kedit --caption 'My File' '/tmp/myfile.txt'";
system(QFile::encodeName(s));

QString KMacroExpander::expandMacrosShellQuote	(	const QString &	str,
		const QHash< QChar, QStringList > &	map,
		QChar	c = QLatin1Char('%')
	)

Same as above, except that the macros expand to string lists.

If the macro appears inside a quoted string, the list is simply join(" ")ed together; otherwise every element expands to a separate quoted string.
