Description

Function name Description
glob() glob can search file and directory with wildcard (* and ?).

glob は，wildcard (* と ?) を用いた，ファイルとディレクトリを探索できます．
glob_pt() glob_pt is a type of glob with a variable indicating the file type in the returning value. Options can take d, f, r and p. There options can be specified independently in no particular order.
Options:
- d: getting directory name
- f: getting file name
- r: recursive directory
- p: using sstd::pathmatch() instead of sstd::strmatch() internally

glob_pt は，glob の戻り値にファイルタイプを示す変数が追加されたバージョンです．オプションには d, f, r, p があり，それぞれ独立に，順不同で指定できます．

Usage01: getting only file without recursive option

  • main.cpp 
    #include <sstd/sstd.hpp>

int main(){
    sstd::mkdir("./tmp");
    sstd::system("touch ./tmp/a.txt");
    sstd::system("touch ./tmp/b.csv");
    sstd::system("touch ./tmp/c.txt");

    std::vector<std::string> vStr = sstd::glob("./tmp/*.txt");
    sstd::printn(vStr);

    std::vector<struct sstd::pathAndType> vPt = sstd::glob_pt("./tmp/*.txt");
    sstd::printn(vPt);

    sstd::rm("./tmp");
}
  • example.txt 
    vStr = ["./tmp/a.txt" "./tmp/c.txt"]
vPt = ["path: ./tmp/a.txt, type: file" "path: ./tmp/c.txt, type: file"]

Usage02: getting file and directory with recursive option

  • main.cpp 
    #include <sstd/sstd.hpp>

int main(){
    sstd::mkdir("./tmp");
    sstd::mkdir("./tmp/a");
    sstd::mkdir("./tmp/b");
    sstd::mkdir("./tmp/c");
    sstd::system("touch ./tmp/a.txt");
    sstd::system("touch ./tmp/b.csv");
    sstd::system("touch ./tmp/c.txt");

    std::vector<std::string> vStr = sstd::glob("./tmp/*", "dfr");
    sstd::printn(vStr);

    std::vector<struct sstd::pathAndType> vPt = sstd::glob_pt("./tmp/*", "dfr");
    sstd::printn(vPt);

    sstd::rm("./tmp");
}
  • example.txt 
    vStr = ["./tmp/a" "./tmp/a.txt" "./tmp/b" "./tmp/b.csv" "./tmp/c" "./tmp/c.txt"]
vPt = ["path: ./tmp/a, type: directory" "path: ./tmp/a.txt, type: file" "path: ./tmp/b, type: directory" "path: ./tmp/b.csv, type: file" "path: ./tmp/c, type: directory" "path: ./tmp/c.txt, type: file"]
