Prekladanie cuzdojazicneho zdrojaka do SVK? – C / C++ – Fórum – Programujte.com

pomohlo by mi kebyze prelozim WOLF4SDL do svojho jazyka , vratane programatorskych prikazov

Nechápem. No, (kvalitné) preklady sa vždy zídu. Ale aj tak, sme tu všetci developeri, a angličtina je proste základ.

Jedna věc je překládat texty. Takové snahy, pokud jsou kvalitní, většinou vítám. Překládat zdrojový kód (byť jen komentáře) je IMHO do nebe volající blbost. 

Takze najviac komentare prelozit?
