# Concurrent [![TravisCI_status](https://travis-ci.org/Chocobo1/concurrent.svg?branch=master)](https://travis-ci.org/Chocobo1/concurrent) [![AppVeyor_status](https://ci.appveyor.com/api/projects/status/github/Chocobo1/concurrent?branch=master&svg=true)](https://ci.appveyor.com/project/Chocobo1/concurrent)

A naive tool that take cmd line commands (from text file or pipe) and execute concurrently:

![screencast.gif](./screencast.gif)

It will automatically distribute the commands to CPU cores, the logical ones as much as you have except one (which is reserved for OS).

If you seek a more powerful tool: [GNU Parallel](https://www.gnu.org/software/parallel/).

## Usage

* Issue commands via stdin (pipe) input:

  ```shell

someCmdGenerator | concurrent -

  ```

* Issue commands via file:

  ```shell

concurrent 

  ```

## Special directives

* Fence: Will wait for **all** executing commands (i.e. all commands before this directive) to finish and then continue on.

  ```

### Fence ###

  ```

 or

  ```

rem Fence rem

  ```

* Change the number of commands executing in parallel:

  ```

### Threads: <# of jobs> ###

  ```

 or

  ```

rem Threads: <# of jobs> rem

  ```

* Comment keyword: {`#`, `rem`}, the same as shell script & batch comment keyword.

  Lines starting with these keywords will be ignored.

## Compile

Get yourself a [C++11 compiler](http://en.cppreference.com/w/cpp/compiler_support) and run:

  ```shell

cd src

make -j2

  ```

To run tests:

  ```shell

git submodule update --init --remote --depth 1  # init git submodule

cd src

make -j2 test

  ```
