You can use a bytes.Buffer to create a single csv.Reader and write the log
lines into that buffer.
The code will look roughly like this https://play.golang.org/p/gbCPwSsx5gy .
However, depending on the implementation of strings.Reader and the level of
optimization the Go compiler does, your approach of creating a new csv.Reader
for every iteration might actually be faster and consume less memory than my
code.
Greetings all,
I have a channel of 'string', where each item is a single CSV log line that I
want to convert to columns using "encoding/csv"
Currently, I am creating a new csv.Reader at each iteration for each item,
which is much more work than it needs to be.
<snip>
for i := range feederChan {
r := csv.NewReader(strings.NewReader(i))
a := r.Read()
// Do stuff with a
// ...
}
</snip>
I would really appreciate sharing with me if there's a way to iterate through a
'chan string' using 'csv.Reader()' without the need to create a new Reader for
each item.
Thanks.
