Quote Buffer

Build Status


Automated code generation can be used to eliminate the need of writing and maintaining repetitive parts of a software. In order to add a string literal to generated source code, it is required to create strings whose content is delimited by escaped quotation marks.

In the following such strings are called quoted strings. QuoteBuffer simplifies adding quoted strings to a string buffer.


QuoteBuffer extends Dart's StringBuffer. It adds the following methods for writing quoted strings to the buffer:

  • writeQ(Object obj): Converts an object to a quoted string.
    var buffer = QuoteBuffer();
    // Adds:'\'29\''
  • writelnQ(Object obj): Converts an object to a quoted string followed by a newline symbol.
    // Adds:'\'name\'\n'
  • writeAllQ(Iterable<Object> objects,String separator): Converts a list of objects to a quoted string. Separators are optional.
    // Adds:'\'one,two\''
    buffer.writeAllQ(['one','two'], ',');
  • writelnAllQ(Iterable<Object> objects,String separator): Converts each object in the list of objects to a quoted string followed by a newline symbol. Separators are optional.
    // Adds:
    // '\'one\';\n'
    // '\'two\';\n'
    // '\'three\'\n'
    buffer.writelnAllQ(['one','two','three'], ';');


The examples located in the folder example show how to use the class QuoteBuffer to simplify the generation of string literals whose content is enclosed by escaped quotation marks. One of the programs demonstrates how to use QuoteBuffer in the context of code generation.
