# glob-cpp

------------

Glob CPP is still in development, and more testing needs to be done.

------------

Glob CPP is a header only library based on STL regular expression to perform glob operation on string, or on filesystem.

```

?(pattern-list)   Matches zero or one occurrence of the given patterns

*(pattern-list)   Matches zero or more occurrences of the given patterns

+(pattern-list)   Matches one or more occurrences of the given patterns

@(pattern-list)   Matches one of the given patterns

!(pattern-list)   Matches anything except one of the given patterns

```

## Glob Examples

```

*.jpg         : All JPEG files

[A-Z]*.jpg    : JPEG files that start with a capital letter

*!(.jpg|.gif) : All files, except JPEGs or GIFs.

```

## Examples

### Match with string

Verify is a given string match with glob expression.

```cpp

#include "glob.h"

int main () {

  glob::glob g("*.pdf");

  bool r = glob::glob_match("test.pdf", g);

  std::cout << "match: " << r?"yes":"no" << "\n";

  return 0;

}

```

### Get match substrings

Print the matches found on the target sequence of characters after a glob matching operation.

```cpp

#include "glob.h"

int main () {

  glob::glob g("*.pdf");

  glob::cmatch m;

  if (glob::glob_match("test.pdf", m, g)) {

    for (auto& token : m) {

      std::cout << "sub string: " << token << "\n";

    }

  }

  

  return 0;

}

```

### Get files from match operation in a directory and all match substrings

Given a directory, this example list all files that match with the glob expression. For example:

`*.pdf` get all pdf files in the directory, and `**/*.pdf` get all pdf files in all sub directories.

```cpp

#include "file-glob.h"

int main () {

  glob::file_glob fglob{argv[1]};

  std::vector results = fglob.Exec();

  for (auto& res : results) {

    std::cout << "path: " <<  res.path() << "[";

    auto& match_res = res.match_result();

    for (auto& token : match_res) {

      std::cout << " \"" << token << "\" ";

    }

    std::cout << "]" << std::endl;

  }

  

  return 0;

}

```
