## Frequently Asked Questions (FAQ) and Answers
### Q: What's the recommended file type extension for CSV <3 YAML files?
The recommended file format for CSV <3 YAML files is `.csv` :-) or use `.yaml.csv` (to highlight
the fact of the YAML encoding rules).
## Do-It-Yourself (DIY) - No CSV <3 YAML Parser in Your Language? - Build Your Own
Build your own parser:
- Read the input (e.g. string or file) line-by-line
- If the line is blank (only whitespace), skip the line.
- If the line starts with a hash mark (`#`), skip the comment line.
- Otherwise wrap the line in (`[]`) and pass along to the YAML parser :-).
Example in Ruby:
``` ruby
def parse( input )
records = []
input.each_line do |line|
## note: chomp('') if is an empty string,
## it will remove all trailing newlines (e.g. \n or \r\n) from the line
line = line.chomp( '' )
## strip leading and trailing whitespaces (space and tab)
line = line.strip
next if line.empty? ## skip blank lines
next if line.start_with?( '#' ) ## skip comment lines
## note: auto-wrap in array e.g. with []
records << YAML.load( "[#{line}]" )
end
records
end
```
