CSV++
CSV++ takes a <DELIMITER>
separated input file and a JSON format specification
and turns it into Ruby Objects. See test/sample_inputs/simple.txt
and
test/sample_formats/simple.json
for example.
Installation
Add this line to your application's Gemfile:
gem 'csvpp'
And then execute:
$ bundle
Or install it yourself as:
$ gem install csvpp
Usage
CSVPP.parse(
input: 'test/sample_inputs/simple.txt',
format: 'test/sample_formats/simple.json'
) # => [{"v1"=>34, "line_number"=>1, "v2"=>"foobar"}, {"v1"=>99, "line_number"=>2, "v2"=>"hi there"}]
CLI
CSV++ comes with a CLI. To print a JSON representation of an input file, pass a
file argument and provide a format specification file with -f
, e.g.:
$ csvpp test/sample_inputs/simple.txt -f test/sample_formats/simple.json
{
"vars": [
{
"line_number": 1,
"v1": 34,
"v2": "foobar",
"v3": 1.1,
"v4": false
},
{
"line_number": 2,
"v1": 99,
"v2": "hi there",
"v3": 2.2,
"v4": true
},
{
"line_number": 3,
"v1": null,
"v2": "Missing",
"v3": null,
"v4": true
}
]
}
