Writing the code was a relaxed experience, not in the 19%D last place because it was accompanied by listening to those nice 20%D Vienna Teng cd's (who decided that making music was more fun than 21%D programming, but then, she may not know \TEX\ and \LUA). 22 23\unprotect 24 25\registerctxluafile{char-def}{} 26\registerctxluafile{char-ini}{} 27\registerctxluafile{char-utf}{} 28\registerctxluafile{char-cjk}{} 29 30%D We enable collapsing (combining characters) by default, but 31%D since the source files are rather simple, we postpone the 32%D initialization till runtime. 33 34% \appendtoks 35% \clf_enableutf % not needed when we create a format so we do it now 36% \to \everyjob 37 38%D The next one influences input parsing. 39%D 40%D \starttyping 41%D \definecomposedutf 318 108 126 % lcaron 42%D \stoptyping 43 44\unexpanded\def\definecomposedutf#1 #2 #3 % 45 {\clf_addgrapheme{#1}{#2}{#3}} 46 47\protect 48 |
