Especially, scripting language Lua is designed on the assumption that its interpreter is embedded in a C program. In fact, a lot of existing software written in C embed Lua interpreter. However, when embedding a Lua program in a C program, it is necessary for the programmer to use complicated C APIs provided by Lua for trasferring data between C and Lua. This increases the developing cost of programs within which C and Lua cooperate. Worse, obeying protocols of Lua's C APIs spoils the readability of source programs. To resolve this problem, we propose a new language LuCa that extends C to make it possible to embed Lua code directly, and implement a LuCa processor. In a LuCa program, embedded Lua code can access variables and fucntions in C. Thus, using LuCa enables the programmer to write Lua-like code without explicit C APIs and reduces the programmer's burden. LuCa processor converts a given LuCa code into a C code. Since cooperating part of C and Lua is converted into C code with existing C APIs, the LuCa processor does not require special C compiler and Lua interpreter. We describe LuCa language and the implementation of its processor.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"14","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"14","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"8"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
