This Golang library automatically detects the CSV delimiter and returns a *csv.Reader instance.
This is quite a simple implementation, the following caveats should be considered:
- The whole reader will be read into memory before returning the CSV reader, so it is not suitable for massive CSV's.
- By default it checks for the following delimiters
, \t ; : |, pass in a custom*csvd.Snifferto change this. - It's not bullet proof! Quick and simple.
package main
import (
"strings"
"github.com/jfyne/csvd"
)
func main() {
example := `first_name;last_name;username
"Rob";"Pike";rob
Ken;Thompson;ken
"Robert";"Griesemer";"gri"
`
// Get regular "encoding/csv" with its delimiter detected.
reader := csvd.NewReader(strings.NewReader(example))
// reader.Comma will be ';' instead of the default. Use as usual
reader.ReadAll()
customDelimiter := `first_name$last_name$username
"Rob"$"Pike"$rob
Ken$Thompson$ken
"Robert"$"Griesemer"$"gri"
`
// Create a custom Sniffer
s := csvd.Sniffer(20, '$', '*')
// Use the custom sniffer to parse the CSV
reader2 := csvd.NewReader(strings.NewReader(customDelimiter), s)
// reader2.Comma will be '$' now
reader2.ReadAll()
}
