In R you can change the floating point character $. by other character using
read.csv("file.csv",dec=",")
I think it is useful. You should add a decimal: aChar method to NeoCSVReader and change NeoNumberParser to be able to parse float numbers separated by the assigned "decimal point" character.

Thanks for NeoCSV! It's super useful (I'm using it on 1G csv files now...)

I was looking at https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/NeoCSV/NeoCSV.html which seems to have more info than the readme here. I wasn't sure which one is (supposed to be) more recent, but Google tends to find the ci.inria.fr one when a search for NeoCSV is done.

Anyway, I think I found a mistake in the selective read example in 4.3:

Array streamContents: [ :out |
  'paul.csv' asFileReference readStreamDo: [ :input |
      (NeoCSVReader on: (ZnBufferedReadStream on: in))
         skipHeader;
         addIntegerField;
         addSymbolField;
         addIntegerField;
         addFieldConverter: [ :x | x = #true ];
         do: [ :each |
            each third < 1000
               ifTrue: [ out nextPut: each ] ] ] ].

The third line should have

(ZnBufferedReadStream on: input)
