Constructor.
- Parameters:
-
c escape char indicating start of macros, or QChar.null for none
| QChar escapeChar | ( | self ) |
Obtain the macro escape character.
- Returns:
- escape char indicating start of macros, or QChar.null if none
| int expandEscapedMacro | ( | self, | ||
| QString | str, | |||
| int | pos, | |||
| QStringList | ret | |||
| ) |
This function is called every time the escape char is found if it is not QChar.null. It should determine whether the string starting at pos witin str is a valid macro and return the substitution value for it if so.
- Parameters:
-
str the input string pos the offset within str. Note that this is the position of the occurrence of the escape char ret return value: the string to substitute for the macro
- Returns:
- If greater than zero, the number of chars at pos in str to substitute with ret (i.e., a valid macro was found). If less than zero, subtract this value from pos (to skip a macro, i.e., substitute it with itself). If zero, scanning continues as if no escape char was encountered at all.
| expandMacros | ( | self, | ||
| QString | str | |||
| ) |
Perform safe macro expansion (substitution) on a string.
- Parameters:
-
str the string in which macros are expanded in-place
| bool, int pos expandMacrosShellQuote | ( | self, | ||
| QString | str | |||
| ) |
Same as above, but always starts at position 0, and unmatched closing parens and braces are treated as errors.
| int expandPlainMacro | ( | self, | ||
| QString | str, | |||
| int | pos, | |||
| QStringList | ret | |||
| ) |
This function is called for every single char within the string if the escape char is QChar.null. It should determine whether the string starting at pos within str is a valid macro and return the substitution value for it if so.
- Parameters:
-
str the input string pos the offset within str ret return value: the string to substitute for the macro
- Returns:
- If greater than zero, the number of chars at pos in str to substitute with ret (i.e., a valid macro was found). If less than zero, subtract this value from pos (to skip a macro, i.e., substitute it with itself). If zero, no macro starts at pos.
| setEscapeChar | ( | self, | ||
| QChar | c | |||
| ) |
Set the macro escape character.
- Parameters:
-
c escape char indicating start of macros, or QChar.null if none
