Hi everyone,

A Lasso 9 "port" (and partial rewrite) of Jason Huck's CSV type is now available at https://github.com/iamjono/csv

Suggestions welcome - push any patches to me, and even feature requests!

Thanks
Jono


csv
A basic type for reading, writing, and serving CSV files. Based on previous Lasso 8 version from Jason Huck

Properties
===== ->fields - An array containing the column names for the CSV file. Will default to [field_names] on creation if/when possible.

->rows - An array of arrays containing the data for the CSV file. Will default to [rows_array] on creation if/when possible.

->loadpath - String, the path to a CSV file to parse into the type.

->titlerow - Boolean, whether or not the CSV file contains a title row. Pertains to both loading and saving files. Defaults to false.

->savepath - String, where to save the CSV file.

->filename - String, the name to use when saving the file. Defaults to "results.csv."

Methods
==== ->parseline - Parses an individual line of a loaded file. Used internally by ->load.

->load - Loads a CSV file from the given path. Optionally accepts a boolean 'titlerow' parameter indicating whether or not the source file contains a title row.

->output - Returns the contents of the object formatted as a CSV file. Used internally by ->save and ->serve.

->save - Saves a CSV file to the given path.

->serve - Serves a CSV file to the browser using the csv mime type and filename supplied.

->addrow - Accepts an array to add to ->rows.

Sample Usage
========= local(fieldnames = array('Color','Number','Size'))

local(data = array(
array('Red',1,'small'),
array('Green',2,'medium'),
array('Blue',3,'large'),
array('Black',4,'extra large with "some" quotes')
)
)

local(stuff = csv(
-fields = #fieldnames,
-rows = #data,
-titlerow = true
)
)

#stuff->addrow(array('Orange',5,'tiny'))

#stuff->save('atestfile.csv')

#stuff = csv
#stuff->load('atestfile.csv')
#stuff->output
