You provide a transformation of the data into a line-oriented text format, and git uses its regular diff tools to generate the output." Does it mean that the textconv filter is called for each line ? The opposite being called once for the whole file. Regards, Laurent. ``` ## Matthieu Moy, 2012-06-20 12:17 Subject: Re: Is the textconv filter called for each line ? or once for the file ?

No. What would "for each line" mean, since textconv is essentially meant to be called on binary files? -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ``` ## Junio C Hamano, 2012-06-20 18:35 Subject: Re: Is the textconv filter called for each line ? or once for the file ?

I think the key phrase Laurent has missed is "*into* a line-oriented text format". The input may or may not be line-oriented. The output is expected to be. ```
