Function Documentation

◆ expandMacros() [1/4]

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

Definition at line 369 of file kmacroexpander.cpp.

◆ expandMacros() [2/4]

KCOREADDONS_EXPORT 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
strThe string to expand
mapmap with substitutions
cescape char indicating start of macro, or QChar::null if none
Returns
the string with all valid macros expanded
// Code example
map.insert('u', "/tmp/myfile.txt");
map.insert('n', "My File");
QString s = "%% Title: %u:%n";
// s is now "% Title: /tmp/myfile.txt:My File";
QString expandMacros(const QString &ostr, const QHash< QChar, QString > &map, QChar c)
Perform safe macro expansion (substitution) on a string.

Definition at line 345 of file kmacroexpander.cpp.

◆ expandMacros() [3/4]

KCOREADDONS_EXPORT 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.

Definition at line 361 of file kmacroexpander.cpp.

◆ expandMacros() [4/4]

KCOREADDONS_EXPORT 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
strThe string to expand
mapmap with substitutions
cescape char indicating start of macro, or QChar::null if none
Returns
the string with all valid macros expanded
// Code example
map.insert("url", "/tmp/myfile.txt");
map.insert("name", "My File");
QString s = "Title: %{url}-%name";
// s is now "Title: /tmp/myfile.txt-My File";

Definition at line 353 of file kmacroexpander.cpp.

◆ expandMacrosShellQuote() [1/4]

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

Definition at line 373 of file kmacroexpander.cpp.

◆ expandMacrosShellQuote() [2/4]

KCOREADDONS_EXPORT 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
strThe string to expand
mapmap with substitutions
cescape 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
map.insert('u', "/tmp/myfile.txt");
map.insert('n', "My File");
QString s = "kwrite --qwindowtitle %n %u";
// s is now "kwrite --qwindowtitle 'My File' '/tmp/myfile.txt'";
system(QFile::encodeName(s));
QString expandMacrosShellQuote(const QString &ostr, const QHash< QChar, QString > &map, QChar c)
Perform safe macro expansion (substitution) on a string for use in shell commands.
QByteArray encodeName(const QString &fileName)

Definition at line 349 of file kmacroexpander.cpp.

◆ expandMacrosShellQuote() [3/4]

KCOREADDONS_EXPORT 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.

Definition at line 365 of file kmacroexpander.cpp.

◆ expandMacrosShellQuote() [4/4]

KCOREADDONS_EXPORT 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
strThe string to expand
mapmap with substitutions
cescape 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
map.insert("url", "/tmp/myfile.txt");
map.insert("name", "My File");
QString s = "kwrite --qwindowtitle %name %{url}";
// s is now "kwrite --qwindowtitle 'My File' '/tmp/myfile.txt'";
system(QFile::encodeName(s));
