Better support for dev

Description

Add a new command to run a wip-solution in debug mode.

Design

The new command would look like:

$ ./aoc debug -d9 -p2 -abadouralix -r
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Running submissions for day 09:

* part 2:
---------------------------------------------------
On input from badouralix
---------------------------------------------------
<stdout of badouralix solution on badouralix input>
...

The idea is to prevent python main process to read a subprocess stdout, and let the shell print the subprocess stdout. The runner would not use the flag stdout=PIPE as it currently does:

Create go symlink if not exist

Description

./aoc create only creates a symlink to the go solution in workspace/ after it successfully created the go solution file. In particular, if the solution file already exists, it will skip creating the symlink even though it does not exist.

Design

Catch the exception and keep moving?

Removing the following line would also help creating all missing files, instead of exiting at the first exception:

Run as fast as possible

Description

Stop running super-mega-long solutions.

Design

Add a boolean flag --fast or --no-slow to the run command

Timeout

Discard solutions that take more than 5s to run.

We could also add a integer flag --timeout to override the default 5s timeout.

Slow flag

Add a file to list all slow solutions (blacklist) or all fast solutions (whitelist) and use this file to deduce solutions to be run.

All together

A naive approach for the timeout feature would be running the solution and force stop the execution after 5s. If a solution timeouts on the first input, it will likely timeout on all other inputs. Which means for each input, we run spend 5s for nothing.

This is improvable by flagging the solution as slow on the first input and avoid running it on other inputs. In a sense, this is a dynamic version of slow flag with a discrimination based on timeout.
