Moved to atcoder-env

C++ development environment for competitive programming.
This environment is meant to be used in VSCode with a Remote - Containers extension.

On any computer, you can use this environment to write/debug C++ source codes for competitive programming.
(VSCode and some of its extensions must be installed.)

Follow these steps to open this sample in a container using the VS Code Remote - Containers extension:

1. If this is your first time using a development container, please ensure your system meets the pre-reqs (i.e. have Docker installed) in the getting started steps.

2. To use this repository, open a locally cloned copy of the code:

   • Clone this repository to your local filesystem.
   • Press F1 and select the Remote-Containers: Open Folder in Container... command.
   • Select the cloned copy of this folder, wait for the container to start, and try things out!

Once you have this sample opened, you'll be able to work with it like you would locally.

Note: This container runs as a non-root user with sudo access by default. Comment out "remoteUser": "vscode" in .devcontainer/devcontainer.json if you'd prefer to run as root.

Some things to try:

1. Edit:
   • Open main.cpp
   • Try adding some code and check out the language features.
   • Notice that the C++ extension is already installed in the container since the .devcontainer/devcontainer.json lists "ms-vscode.cpptools" as an extension to install automatically when the container is created.
2. Terminal: Press ctrl+shift+` and type uname and other Linux commands from the terminal window.
3. Build, Run, and Debug:
   • Open main.cpp
   • Add a breakpoint (e.g. on line 7).
   • Press F5 to launch the app in the container.
   • Once the breakpoint is hit, try hovering over variables, examining locals, and more.

• at
  -> atcoder-tools

※ This is a little bit outdated! Please see .devcontainer/conf/.bashrc for more detail.

• at-gen
  Example: at-gen abc200
  This should run following tasks.

  1. Generate contest directory.
  2. Change directory to abc200.
  3. Open main.cpp for problem A.
     ※ This should also work for the contest of which the first problem is not named A. See the definition in .devcontainer/conf/.bashrc to know how it works.

• at-open
  Example: at-open abc200
  This should run following tasks.

  1. Change directory to abc200.
  2. Open main.cpp for problem A.

• at-change
  Example: at-change B
  This should take you to the directory of Problem B in the same contest directory.
  ※ You must be in either the contest directory or the problem directory of the contest directory.
  Eg.
  /workspaces/cpp-environment/atcoder/abc249
  or
  /workspaces/cpp-environment/atcoder/abc249/A

• at-clean
  Remove all files/directory (other than .gitignore) in atcoder/.
