CSV

A CSV (comma separated values) reader and writer

The reader reads a table of strings from a CSV file; i.e. an array (rows) of arrays (fields) of strings.

The functionality is extremely bare on purpose. The fancy stuff, like typing columns and automatic conversions is left out and must be handled by the application using this.

Writing:

	CSV writeTable: #(#('key' 'name' 'value') #('answer' 'the' '42')) to: 'file.csv' asFilename.

Reading:

	CSV tableFromFile: 'file.csv' asFilename.
	CSV tableVerboselyFromFile: 'file.csv' asFilename.
	CSV tableFromFile: 'file.csv' asFilename encoding: #utf8.
	CSV tableFromStream: 'file.csv' asFilename readStream.
	CSV tableFromStream: 'file.csv' asFilename readStream separator: $;.

  • CSV.pcl and CSV.pst together is a parcel for VisualWorks.
  • CSVvw.st is a fileout in VisualWorks XML source format.
  • CSV.st is a fileout in the original chunk format which can be read by humans and all Smalltalks.
