Function Documentation

KDECORE_EXPORT QString KMacroExpander::expandMacros const QString str,
const QMap< QChar, QString > &  map,
QChar  c = '%'
 

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
 QMap<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";

KDECORE_EXPORT QString KMacroExpander::expandMacrosShellQuote const QString str,
const QMap< QChar, QString > &  map,
QChar  c = '%'
 

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
 QMap<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));

KDECORE_EXPORT QString KMacroExpander::expandMacros const QString str,
const QMap< QString, QString > &  map,
QChar  c = '%'
 

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
 QMap<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";

KDECORE_EXPORT QString KMacroExpander::expandMacrosShellQuote const QString str,
const QMap< QString, QString > &  map,
QChar  c = '%'
 

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. 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
 QMap<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));

KDECORE_EXPORT QString KMacroExpander::expandMacros const QString str,
const QMap< QChar, QStringList > &  map,
QChar  c = '%'
 

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