quote_buffer 0.1.3

Simplifies adding strings whose content is delimited by escaped quotation marks to Dart's string buffer.

Quote Buffer

Introduction

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 extends Dart's StringBuffer by providing methods that simplify adding quoted strings to the buffer.

Usage

To use this library include quote_buffer as dependency in your pubspec.yaml file. The buffer can be configured to use escaped single or double quotation marks. The constructor parameter delimiter defaults to QuotationMark.Single.

/// QuoteBuffer with escaped single quotation mark as string delimiter.
final bufferS = QuoteBuffer();

/// QuoteBuffer with escaped double quotation mark as string delimiter.
final bufferD = QuoteBuffer(delimiter: QuotationMark.Double);

The section below lists the methods provided for writing quoted strings to the buffer and shows the console output obtained by printing the buffer.

1. writeQ(Object obj)

   Writes delimiter, obj, delimiter to the buffer.

   bufferS.writeQ(29);
   print(bufferS.toString()); // Console output below \/
   

   '29'
   

2. writelnQ(Object obj)

   Writes delimiter, obj, delimiter, newline symbol to the buffer.

   final bufferS = QuoteBuffer();
   bufferS.writelnQ('name');
   print(bufferS.toString()); // Console output below \/
   print('--- ---');
   

   'name'
   
   --- ---
   

3. writeAllQ(Iterable objects, [String separator])

   Writes delimiter, sequence of objects, delimiter to the buffer.

   bufferD.writeAllQ(
     ['one','two','three','four'],
      ',',
   );
   print(buffer.toString()); // Console output below \/
   

   "one, two, three, four"
   

4. writelnAllQ(Iterable objects, {String separator1, String separator2})

   Writes objects in sequence: delimiter, objects[0], separator1, delimiter, separator2, newline symbol, etc.

   bufferD.writelnAllQ(
     ['one','two','three','four'],
     separator1: ' #',
     separator2: ',',
   );
   print(bufferD.toString()); // Console output below \/
   print('--- ---');
   

    "one #",
    "two #",
    "three #",
    "four"
   
    --- ---
   

Examples

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.
