Miks mulle Rake meeldib

Esmane kokkupuude Rakega oli mul ühest avatud lähtekoodiga .NET-i projektist. Kuna NAnt ja MSBuild on küllaltki mürarikkad, siis ei mõistnud hästi, et miks selle projektiga tegelejad ei investeerinud piisavalt aega, et see veel loetavamaks teha. Siiski hea, et edasiminek oli.

Praegu käsil olevas projektis viin vaikselt NAnt skriptid üle Rake ja nagu eelnevalt ka lubasin näidet selle kohta, siis siin see ka on.

NAnti skriptidest mõned lõigud ka võrdluseks.

Kui teil on ideid, kuidas seda veel paremaks teha, siis andke teada. Praegu on alles pool teekonda läbitud.
