Dear all, in order to create tables of CJK characters I thought of having groff do the computation rather than making a huge text file in tabular form.
I thought of a loop that traverses 0x0 to 0xF (i.e., 0 .. 15 in decimal notation) for writing rows of 16 characters: .fam Song .\" Create pseudo hash, rather LUT for hex numbers .ds 10 A .ds 11 B .ds 12 C .ds 13 D .ds 14 E .ds 15 F .\" The first 16 Chinese characters of Unicode CJK are U+4E00 to U+4E0F. .\" Loop through positions 0..15 and print character in \[u....] notation. .\" If the last digit is below 10, use it directly, otherwise convert it via LUT above. .nr number 0 1 .while (\n[number] < 16) \{\ .ie (\n[number] < 10) \[u4E0\n[number]] .el \[u4E0\*[\n[number]]] .nr number +1 .\} So far, everything works perfectly. However, if I wrap this loop in a macro like .de myline .\" material as above .. and try to call with \n[myline] or .myline then I run into an infinite loop. Where is my mistake?
