This is the new mailing list for Ruby Spreadsheet.

http://groups.google.com/group/rubyspreadsheet

Any technical, featural or legal question should go here, or as a comment into this blog. Feel free to document on your own site as well and then just send in your link to the ML. You may also write in Japanese if you like 😉 or prefer, the answer may come in english though. English is the preferred language.

Not-For-Profit Licence for Ruby-Spreadsheet

Filed under: Licence, Not For Profit, Release, Ruby, Spreadsheet — Tags: , — zdavatz @ 5:55 pm

Today we received an Email from AtomicObject regarding a free NON-GPLv3 licence for their Non-For-Profit Project SMEToolkit – that code is not OpenSource other code from AtomicObject obviously is OSS. After our first reaction of a flat denial to do so, we had some internal discussions and would be willing to provide AtomicObject with a licence for SMEToolkit under the following circumstances (and maybe more to come):

1. Where will we be credited for our work? Where in the Website and where in the source code? The term to mention would be “ywesee – the Ruby Spreadsheet” that of course would have to be linked i.e. to some new Blog entry on this Blog. Maybe even with this entry.

2. Where, in which countries, and on how many servers do you and will you run http://www.smetoolkit.org/smetoolkit/en?

3. What are the reasons why http://www.smetoolkit.org/ can not be licensed under GPLv3? We would like to state those reasons in the free license.

4. We could only grant our licence for this specific project. Other projects and clients of AtomicObject would not be allowed to use Ruby Spreadsheet under the possibly given licence.

5. We are willing to do this because we want you to see how easy it is to print a spreadsheet with our Software and of course because we want to sell additional licences to you 😉 for your other NON GPLv3 clients.

Lets see how this turns out.

I get an error when trying to open a file with spreadsheet

Filed under: Ruby, Spreadsheet — Tags: , , — zdavatz @ 2:52 pm

Mike Potter reported that he gets an error when he try’s to open a file a file with Ruby Spreadsheet.

http://rubyforge.org/forum/forum.php?thread_id=25135&forum_id=2920

This is due to still having the old ParseExcel installed. You must manually uninstall that (gem uninstall parseexcel), otherwise you will run into all sorts of errors.

highlight cells and print them

Another Bug-Report that came in before Christmas:

http://rubyforge.org/tracker/index.php?func=detail&aid=23287&group_id=678&atid=2677

Spencer Turner reports that he can successfully write a file which can be read, in Excel, however, when he highlights cells and try’s to print them, Excel (OfficeXP on Windows XP) says it cannot find any data.

Looking at the file created in a Raw Text editor,  he does not see any BIFF text added. Once he saves it again from OpenOffice, it is there.

Update: This Bug has been solved here:

The Ruby Spreadsheet

The Spreadsheet Library is designed to read and write Spreadsheet
Documents. As of version 0.6.0, only Microsoft Excel compatible
spreadsheets are supported. Spreadsheet is a combination/complete
rewrite of the Spreadsheet::Excel Library by Daniel J. Berger and the
ParseExcel Library by Hannes Wyss. Spreadsheet can read, write and
modify Spreadsheet Documents.

Changes:

### 0.6.0 / 2008-10-13
Initial upload of the shiny new Spreadsheet Gem after three weeks of
grueling labor in the dark binary mines of Little-Endian Biff and long
hours spent polishing the surfaces of documentation:

* Significantly improved memory-efficiency when reading large Excel Files
* Limited Spreadsheet modification support
* Improved handling of String Encodings
* Runs on top of the ruby-ole Library

Roadmap:

0.7.0: Improved Format support/Styles
0.7.1: Document Modification: Formats/Styles
0.8.0: Formula Support
0.8.1: Document Modification: Formulas
0.9.0: Write-Support: BIFF5
1.0.0: Ruby 1.9 Support;
Remove backward compatibility code

Backward Compatibility:

Spreadsheet is designed to be a drop-in replacement for both
ParseExcel and Spreadsheet::Excel. It provides a number of
require-paths for backward compatibility with its predecessors. If you
have been working with ParseExcel, you have probably used one or more
of the following:

require ‘parseexcel’
require ‘parseexcel/parseexcel’
require ‘parseexcel/parser’

Either of the above will define the ParseExcel.parse method as a
facade to Spreadsheet.open. Additionally, this will alter Spreadsheets
behavior to define the ParseExcel::Worksheet::Cell class and fill each
parsed Row with instances thereof, which in turn provide ParseExcel’s
Cell#to_s(encoding) and Cell#date methods.
You will have to manually uninstall the parseexcel library.

If you are upgrading from Spreadsheet::Excel, you were probably using
Workbook#add_worksheet and Worksheet#write, write_row or write_column.
Use the following to load the code which provides them:

require ‘spreadsheet/excel’

Again, you will have to manually uninstall the spreadsheet-excel library.

If you perform fancy formatting, you may run into trouble as the
Format implementation has changed considerably. If that is the case,
please drop me a line at hannes.wyss@gmail.com and I will try to help
you. Don’t forget to include the offending code-snippet!
