I need to manually tag a large number of sentences choosing between a small, fixed number of short strings as tags for each sentence. I would like to do this with a Pharo GUI that displays sentences one at a time and permit choice of tags using radio buttons. The results need to be saved as a CSV file on the hard drive for further manipulations with python. As a first step, I used Excel to create a test CSV file with two sentences that was saved on the disk drive in the Pharo working directory. I have subsequently tried to import the sentences into Pharo 6.1 32 bit stable. This was done as follows. |workingDir reader result| workingDir := FileSystem disk workingDirectory. myFileName := 'MoonCSV.csv'. stream := workingDir/myFileName readStreamDo: [ :stream | stream contents]. reader := (NeoCSVReader new) separator: Character cr. The separator was changed from a comma to a cr because the inspector showed a cr, not a comma separating the two imported sentences. result := (reader on: stream). result upToEnd. This failed with the following error: Instance of ByteString doesnât understand #atEnd. I donât see how to proceed further. Also I am not clear on the best way to export the sentence and tags to the disk drive.. Any help would be appreciated. Lou Cleveland
