1.0.2 NoMethodError: undefined method `scan' for nil:NilClass

Staring with version 1.0.2 I'm seeing the following error:

     NoMethodError:
       undefined method `scan' for nil:NilClass
     # ./.bundle/ruby/2.7.0/gems/xsv-1.0.2/lib/xsv/helpers.rb:108:in `parse_number_format'

     # ./.bundle/ruby/2.7.0/gems/xsv-1.0.2/lib/xsv/sheet.rb:64:in `each_row'

I'm guessing this was introduced in c653bb8

It seems the format passed to parse_number_format isn't always a string.

The document was generated by caxlsx.

That's interesting and probably specific to caxlsx. Do you have an example xlsx file you can share, by chance?

[jdufresne]

Here is a minimal test case:

require 'caxlsx'
require 'xsv'

p = Axlsx::Package.new
p.workbook.add_worksheet(name: 'Sheet') do |sheet|
  sheet.add_row [1]
end

workbook = Xsv::Workbook.open(p.to_stream)
workbook.sheets.each do |sheet|
  sheet.each_row do |row|
    p row.inspect
  end
end

This results in the following:

$ bundle exec ruby test.rb
.bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/helpers.rb:108:in `parse_number_format': undefined method `scan' for nil:NilClass (NoMethodError)
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sheet_rows_handler.rb:104:in `format_cell'
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sheet_rows_handler.rb:60:in `end_element'
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sax_parser.rb:68:in `block in parse'
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sax_parser.rb:19:in `loop'
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sax_parser.rb:19:in `parse'
	from .bundle/ruby/3.0.0/gems/xsv-1.0.2/lib/xsv/sheet.rb:64:in `each_row'
	from test.rb:11:in `block in <main>'
	from test.rb:10:in `each'
	from test.rb:10:in `<main>'

If I run the same script with Xsv 1.0.1, I get:

$ bundle exec ruby test.rb
"[1]"

FWIW, the same generated document opens LibreOffice and Emacs doc-view-mode.

Here is the doc generated by caxlsx:

test.xlsx

I suppose this is the relevant row?

<row r="1" ><c r="A1" s="0" t="n"><v>1</v></c></row>

Thank you for the examples, it seems indeed some #nil? checks were lost in c653bb8.

Could you test with the master branch and see if that fixes it?

Yup! All looks good here. Thanks for the very quick response and fix! 🎉

You're welcome! Released Xsv 1.0.3 with the fix
