CPP-File-Manager

C++ File Manager allows you to list files in C++, ignore extensions (or just list specified extensions) and write the whole directory structure into a fancy tree-like structure which can be integrated in Markdown files. This is the first release. Please file issues with [FEATURE REQUEST] in the title, and we'll be happy to take a look at it.

The C++ File Manager provides the following functions to users:

  1. clear() - Clears the memory allocated to corePath.
  2. clear(std::string new_path) - Assigns a new path to the corePath variable.
  3. info() - Prints the corePath assigned to the FileManager object to the console.
  4. list_files(std::vector<std::string> extensions, bool ignore_extensions) - Lists the files and directories in corePath. The first argument is extensions which is a vector of file extensions to be ignored. These extensions are ignored only when the second argument i.e. ignore_extensions is set to true.
  5. writeToFile(std::vector<string> ignore_dirs, std::vector<std::string> ignore_extension) - Writes the tree structure for the files and directories in corePath into a .txt file. This functions iterates till the innermost files of all the directories. The first argument ignore_dirs contains a vector of directories to be ignored in the tree structures. Similarly, the second argument ignore_extensions contains a vector of files extensions to be ignored in the final tree structure.

Usage

Using Binary

The fmanager binary has the following options :

  -h  --help                        Print usage.
  -p  --path filePath               Input path (to be iterated).
  -l  --list_files                  Call the list files function.
  -t  --tree                        Call the tree function.
  -d --ignore_dirs dir1,dir2        Ignore dirs while creating tree
  -e --ignore_extensions ext1,ext2  Ignore extensions while creating tree
  -s --separator                    Separator you want for your tree output

Listing files in a directory

Command: fmanager -p samples

By default, it will list files in the given directory (here samples). Output will look like this:

Got path: samples
sample.cpp
README.md
libcpp-file-manager.a
CMakeLists.txt
FileManager.hpp

Building tree of the given directory and ignoring directories and extensions

./fmanager -p ./ -t -d include,.git -e .cpp
OR
./fmanager --path ./ --tree --ignore_dirs include,.git --ignore_extensions .cpp

Got path: ./
tree.txt
CMakeLists.txt
samples
src
.github
README.md
.git
include

The tree.txt file stores the following directory structure:

|-- tree.txt
|-- CMakeLists.txt
|-- samples
    |-- libcpp-file-manager.a
    |-- CMakeLists.txt
    |-- README.md
    |-- FileManager.hpp
|-- src
|-- .github
    |-- workflows
        |-- build-filemanager.yml
|-- README.md
|-- .git
|-- include

In case you want to change the separator from default (|--) to something like - or *, do:

./fmanager -s '-' -t
./fmanager --separator '-' --tree

The generated tree.txt will now contain - instead of |--:

- tree.txt
- CMakeLists.txt
...

Using the library in your C++ Code

To be able to use FileManager library, head over to the latest release and download .a (library file) and .hpp (header file). Copy these files in your current folder (or wherever you desire, just remember the path). To compile, use:

g++ filename.cpp -L . -lcpp-file-manager -o out

Here are a few steps on using the library in your code:

  1. Create an object of Filemanager class and initialize it with a path:
std::string path = "/home/BuffetCodes/Documents/CPP-File-Manager"; // Change this with your path, either relative or absolute
FileManager file(path);
  1. The file.list_files() function returns a vector containing names of files/directories with additional information. We can iterate through it as follows:
// The type returned is a struct, head over to the header file for more details on it
for (auto const& item: file.list_files()) {
    // Use item.rname if you want "just" the name of the file or folder
    // item.name returns absolute path (with respect to the path given)
    // item.is_dir returns true if it's a directory, else false
    std::cout << item.name << "\n";
}

The output will be as follows:

./tree.txt
./CMakeLists.txt
./samples
./src
./.github
./README.md
./.git
./include
  1. The file.writeToFile() call, creates a text file tree.txt representing the directory structure:
std::vector<std::string> ignore_dirs = {".git", ".github", ".vscode", "build"};
std::vector<std::string> ignore_extensions = {".pyc", ".swp"};
file.writeToFile(/*ignore_folders=*/ ignore_dirs, /*ignore_extensions=*/ ignore_extensions);

Build

The current release (1.0) only supports GNU/Linux Systems. Please head to the relevant opened issues to see the progress on Windows and MacOS. Use the following steps to build from source:

git clone https://github.com/BuffetCodes/CPP-File-Manager.git && cd CPP-File-Manager
mkdir build && cd build
cmake .. && make

The library file: libcpp-file-manager.a will be generated in build/ directory. Copy the header file in include/ and library file from build/ directory to your folder to use it. Or, just head over to the samples folder in this project on how to compile using CMake or g++.
