romaji.c - Romaji to hiragana converter

Simple romaji to hiragana converter written in C.

Building

Run make romaji to build the program. make variables are:

• CC : the C compiler (gcc)
• CFLAGS : additional flags to pass to the compiler ()

No further dependencies are needed besides libc.

Using

I made this with the intent of integrating it to libkkc. With this setup, I can write an ordinary, space-separated romaji japanese sentence and get kana+kanji output, which is really useful for studying the language.

If you want to have a system like mine, compile this program and write the following shell script:

[[ -z $2 ]] && LVL=2 || LVL=$2
romaji "$1" | sed "s/\$/ $LVL/g" | kkc |\
awk -F: '/^([0-9]+:|>> 0:) <[^mcQ]/ {
	line=""
	split($2, splitter, "/")
	lim=length(splitter)
	for (i = 0; i < lim; i++) {
		sub(/^([ \n]*<|.*<)/, "", splitter[i])
		line=(line splitter[i])
	}
	print line
}'

I wrap this shell code in a function that gets sourced by my ~/.zshrc so I can call this by passing the function name, instead of the script name but whichever implementation works. The awk script will be in the repository root as scripts/kkc.awk, it can be used in the output of piped kkc.

Usage alongside scripts/kkc.awk should look as such:

$ romaji "kore ha nani" | sed 's/$/ 4/' | kkc | kkc.awk
コレハナに
コレは何
これは何
これはなに

This repository also includes a sed script for common transliteration of misleading particles like wa (は) as in (kimi wa - 君は) & e as in (nihon e - 日本へ). The script is scripts/norm.sed. Also, this project can integrate with [kakasi] to have full conversion as shown by the graph:
