ruby - How do I open a new XLSX file in roo? -


this code:

newbook = roo::excelx.new('./test.xlsx')

gives me error:

c:/ruby193/lib/ruby/gems/1.9.1/gems/roo-1.13.2/lib/roo/excelx.rb:85:in `block in initialize': file ./test.xlsx not exist (ioerror)

why? how make new xlsx file ruby's roo gem?

roo meant reading excel files only. recommend axlsx gem.

it can used in pure ruby follows

require 'axslx' package = axlsx::package.new workbook = package.workbook workbook.add_worksheet(name: 'some sheet name') |sheet|   sheet.add_row ["header 1", "header 2", "header 3"]   sheet.add_row ["data 1", "data 2", "data 3"] end package.serialize('./test.xlsx')

this create spreadsheet looks like

 -------------------------------- | header 1 | header 2 | header 3 |  -------------------------------- | data 1   | data 2   | data 3   |

axlsx offers pretty can in excel including styling , conditional styling. hope helps out.

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
