Abstract

約20年前からコンピュータでの漢字利用が普及し，標準プログラム言語で日本語データ処理が可能となった．日本語処理は，国際化と一般化されて，国際規格化された．いくつかの言語では，識別名にも漢字などマルチオクテット文字が使用できる．予約語まで日本語にした本格的な日本語プログラム言語も，分かち書きのレベルで，実用化されている．本発表では，より日本語に近い非分かち書きの日本語プログラム言語「まほろば」を提案し，その構文の設計の考え方を中心に論じる．

20 years ago, programming languages have acquired an ability to handle Japanese. Generalizing it to internationalization (i18n), many of i18n facilities of each programming language were accepted as ISO standards. Some programming languages allowed users to use user-defined words in such multi-octet characters as Kanji. Some new Japanese-based programming languages have also been developed and used. In all those languages, keywords and grammar are based on Japanese, but words have to be separated by spaces. We develop a non-separated (No wakachigaki) version of Japanese-based programming language "Mahoroba". "Mahoroba" is a word of ancient Japan, and means a nice country. This presentation describes its syntax design.
