Appending seems to overwrite file

[kcbanner]

I'm trying this:

var fields = 'some,data,values';
var file = csv().from(fields).toPath('posts.csv', {flag: 'a'});

However, the posts.csv file gets overwritten and only contains the data in the fields variable, and none of its previous contents. I was expecting that fields be appended to the end of the file.

Ah, the parameter needed to be flags and not flag as mentioned in the readme.

On my vista/cygwin box when {flags:'a'} (thanks for the tip;) next appending starts from last line (not a new one) say
last (and only) line is:
3,'ala','ma','kota'
after next appending this file will be:
3,'ala','ma','kota',4,'ola','ma','psa'
5,'janek','ma','szczura'
notice: these should be a 3 lines while there are 2

Sorry about the delay, i missed this report while i was on hollidays. I just updated the readme to fix the flags typo. Considering Adam comment, this is somewhat expected since the last line of the csv isn't ended by a line break. I'm not sure what to do with this one, but a solution would be sth like:

var test = csv()
.transform(function(data, index){
    if(index===0){
        test.write('\n',true);
    }
    return data;
})
...;
