NAME
skk - program that emulates Japanese SKK input method SYNOPSIS
skk [options] DESCRIPTION
skk is a tool that reads key sequences from the standard input and converts them to Japanese text according to a Japanese input method called SKK (Simple Kana to Kanji conversion program). More information about the SKK input method itself can be found at: http://openlab.jp/skk/ OPTIONS
The skk command follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -h, --help Show summary of options. -f, --file-dict=FILE Specify path to a file dictionary. -u, --user-dict=FILE Specify path to a user dictionary. -s, --skkserv=HOST:PORT Specify host and port running skkserv. -r, --rule=RULE Specify typing rule. -l, --list-rules List typing rules. EXAMPLE
echo "A i SPC" | skk Converts a capital letter "A" followed by lowercase letter "i" and a space. echo "K a p a SPC K a SPC" | skk Converts a capital letter "K" followed by lowercase letters "a", "p", "a", and a space. Then converts a capital letter "K" followed by "a" and a space. echo "r k" | skk -r tutcode Converts two lowercase letters "r" and "k" with TUT-Code typing rule. echo "a (usleep 50000) b (usleep 200000)" | skk -r nicola Converts two lowercase letters "a" and "b" typed with a 50000 micro seconds interval, and wait 200000 micro seconds, with NICOLA typing rule.
