## Installation
Add this line to your application's Gemfile:
```ruby
gem 'recite_csv'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install recite_csv
## Usage
The following is a example csv file.
``` csv
COL1,COL2
VALUE1,VALUE2
VALUE3,VALUE4
```
Specify header definition using hash object.
``` ruby
class Foo
include ReciteCSV::Reader::Builder.new(col1: "COL1", col2: "COL2")
end
Foo.new("./example.csv").each do |row|
row.class # => Foo::Row
row.col1
row.col2
end
```
Specify header definition using array object.
``` ruby
class Bar
include ReciteCSV::Reader::Builder.new(%w[col1 col2])
end
Bar.new("./example.csv").each do |row|
row.class # => Bar::Row
row.col1
row.col2
end
```
Define custom methods of row object.
``` ruby
class Baz
include(
ReciteCSV::Reader::Builder.new(col1: "COL1", col2: "COL2") do
# define methods of Row class
def col1
"override #{super}"
end
def custom_method
# do somethings..
end
end
)
end
Baz.new("./example.csv").each do |row|
row.class # => Baz::Row
row.col1
row.col2
row.custom_method
end
```
Define custom methods of row object using `row_methods`.
``` ruby
class Qux
include ReciteCSV::Reader::Builder.new(col1: "COL1", col2: "COL2")
row_methods do
def col1
"override #{super}"
end
def custom_method
# do somethings..
end
end
end
Qux.new("./example.csv").each do |row|
row.class # => Qux::Row
row.col1
row.col2
row.custom_method
end
```
Specify file mode and encoding.
``` ruby
class Quux
include ReciteCSV::Reader::Builder.new(col1: "COL1", col2: "COL2")
end
Quux.new("./example.csv", file_options: "rb:UTF-8").each do |row|
# do something
end
```
Convert encoding.
``` ruby
class Corge
include ReciteCSV::Reader::Builder.new(col1: "COL1", col2: "COL2")
end
Corge.new("./example.csv", file_options: ["rb:Shift_JIS:UTF-8", invalid: :replace, undef: :replace]).each do |row|
# do something
end
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
