tabreader library / gem v1.0 - read in tabular datafiles in text in the tabular (TAB) format

[Gerald Bauer]

Hello,

I've published the tabreader library / gem version 1.0 [1]
that lets you read in tabular datafiles in text in the tabular (TAB) format.


Yes, it's as simple as:

line = "1\t2\t3"
values = line.split( "\t" )
pp values
# => ["1","2","3"]

or the "magic" packaged up in `TabReader`:


line = "1\t2\t3"
values = Tab.parse_line( line ) ## or TAB.parse_line or
TabReader.parse_line
pp values
# => ["1","2","3"]


or use the convenience helpers:

txt <<=TXT
1\t2\t3
4\t5\t6
TXT

records = Tab.parse( txt ) ## or TAB.parse or TabReader.parse
pp records
# => [["1","2","3"],
# ["4","5","6"]]

or

records = Tab.read( "values.tab" ) ## or TAB.read or TabReader.read
pp records
# => [["1","2","3"],
# ["4","5","6"]]

or

Tab.foreach( "values.tab" ) do |rec| ## or TAB.foreach or TabReader.foreach
pp rec
end
# => ["1","2","3"]
# => ["4","5","6"]

and so on.


Happy data wrangling with ruby. Cheers. Prost.
