tinyInterpreter

Abstract

getCommandList() read text file, defineing middle of /*~*/ and before // as a commnet. And up to ; is considered as one command list. The returning the value is formed as a list of command.

getCommandList() は txt ファイルを読み込みます．この際に，/*~*/ で囲まれた区間や，同一行中で // より後ろの文字列をコメントとみなし取り除きます． また，; までを一つのコマンドリストみなします．戻り値はコマンドのリストの形式となります．

Header file

namespace sstd{
    std::vector<std::string> getCommandList(const char* pReadFile);
    std::vector<std::string> splitByComma(const std::string& str);
}

Usage

  • tinyInterpreter.txt 
    // - In this file, middle of "/*~*/" and before "//" mean commnets.
//   And a ";" means the end of command.

// comment

/* comment */

cmd01, cmd02,      , cmd04; // comment
cmd05, cmd06, cmd07;        // comment
cmd09, cmd10, cmd11, cmd12;
  • main.cpp 
    #include <sstd/sstd.hpp>

int main(){
    // reading "tinyInterpreter.txt" to vv_ret
    std::vector<std::string> v_line = sstd::getCommandList(R"(./tinyInterpreter.txt)");

    sstd::vvec<std::string> vv_ret(v_line.size());
    for(uint i=0; i<v_line.size(); ++i){
        std::vector<std::string> v_cmd = sstd::splitByComma(v_line[i]);
        for(uint n=0; n<v_cmd.size(); ++n){
            vv_ret[i] <<= v_cmd[n];
        }
    }
    sstd::printn(vv_ret);
}
  • Execution result 
    vv_ret = [["cmd01" "cmd02" "" "cmd04"] ["cmd05" "cmd06" "cmd07"] ["cmd09" "cmd10" "cmd11" "cmd12"]]
