This is nice. Thanks!

Btw, what is the license? :)

CSV (Comma Separated Values) and more generally other delimiter-separated-value formats like TSV are probably the most common data exchange format. A number of implementations of this simple format already exist.

NeoCSV is a more flexible and more efficient reader and writer for this format.

You can find it in

http://mc.stfx.eu/Neo

ConfigurationOfNeoCSV is also available from

http://www.squeaksource.com/MetacelloRepository http://squeaksource.com/MetaRepoForPharo14 http://ss3.gemstone.com/ss/MetaRepoForPharo20

I was just teasing :).

Now that I met you in real life, I really can't imagine you would do something like that, teasing people just for the fun of it ;-) Actually, just yesterday I was further optimizing NeoCSV on an actual example, reading a 3.3 MB file with 140.000 entries like 16777216,17301503,AU 17367040,17432575,MY 17435136,17435391,AU 17498112,17563647,KR 17563648,17825791,CN 17825792,18087935,KR 18153472,18219007,JP The old code did very simply this: readFrom: filename "Read from a CSV with field start,stop,code as in 3651886848,3651887103,BE" "self readFrom: '/Users/sven/Tmp/geo-ip-country/GeoIPCountry.csv'." | instance data | instance := self new. data := OrderedCollection new: 145000. FileStream oldFileNamed: filename do: [ :stream | [ stream atEnd ] whileFalse: [ | tokens range | tokens := stream nextLine findTokens: ','. range := IPAddressRangeCountry from: tokens first asNumber to: tokens second asNumber country: tokens third asSymbol. data add: range ] ]. instance data: data asArray. ^ instance The new code using NeoCSV is this: readFrom: filename "Read from a CSV with field start,stop,code as in 3651886848,3651887103,BE" "self readFrom: '/Users/sven/Tmp/geo-ip-country/GeoIPCountry.csv'." ^ self new data: (FileStream oldFileNamed: filename do: [ :stream | (NeoCSVReader on: stream) recordClass: IPAddressRangeCountry; addIntegerField: #start: ; addIntegerField: #stop: ; addSymbolField: #country: ; upToEnd ]); yourself The new code is simpler, does more internally, and is faster (3.5 vs 2.5 seconds). Yes I am happy, and looking for users ;-) Now I am going back to struggling with Metacello. Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Let me know if I can help...

Thanks, Sean, it is just that I postponed using Metacello for so long, and now I finally forced myself to use it. I am learning slowly because I want to understand what I am doing. So far it goes well. I'll certainly ask for help if I am in trouble. Sven

Hi Sven. Just wanted to make sure you knew about this metacello toolbox guide:

http://seandenigris.com/blog/?p=844

Yes, Paul. I saw that. I am learning slowly because I want to understand what I am doing, that is why I am preferring the manual route. So far it goes well. I'll certainly ask for help if I am in trouble. Sven PS: And thanks again for doing the Zn config for so long !
