sinol-make 1.8.4

CLI tool for creating sio2 task packages

sinol-make

sinol-make is a CLI tool for creating and verifying problem packages for sio2 with features such as:

• measuring time and memory in the same deterministic way as sio2,
• running the solutions in parallel,
• keeping a git-friendly report of solutions' scores,
• catching mistakes in the problem packages as early as possible,
• and more.

Why?

The purpose of the tool is to make it easier to create good problem packages for official competitions, which requires collaboration with other people and using a multitude of "good practices" recommendations. While there are several excellent CLI tools for creating tests and solutions, they lack some built-in mechanisms for verifying packages and finding mistakes before uploading the package to the judge system. As sinol-make was created specifically for the sio2 problem packages, by default it downloads and uses sio2's deterministic mechanism of measuring solutions' runtime, called sio2jail.

Installation

It's possible to directly install sinol-make through Python's package manager pip, which usually is installed alongside Python:

pip3 install sinol-make

pip installs the sinol-make executable in ~/.local/bin/ directory, so make sure this directory is in your PATH. Here's how to add a directory to PATH.

As sio2jail works only on Linux-based operating systems, we do not recommend using operating systems such as Windows or macOS. Nevertheless sinol-make supports those operating systems, though there are additional installation steps required to use other tools for measuring time (which are non-deterministic and produce reports different from sio2):

• Debian-based systems (Ubuntu, usually Windows WSL): apt install time
• Arch-based systems: pacman -S time
• macOS: brew install gnu-time coreutils

Autocompletion (optional)

If you would like to have autocompletion for sinol-make commands, run the following command and refresh the shell (e.g. by opening a new terminal):

activate-global-python-argcomplete

Usage

The available commands (see sinol-make --help) are:

• sinol-make run -- Runs selected solutions (by default all solutions) on selected tests (by default all tests) with a given number of CPUs. Measures the solutions' time with sio2jail, unless specified otherwise. After running the solutions, it compares the solutions' scores with the ones saved in config.yml. If you're using sio2jail, make sure you are not running on efficiency cpu cores. You can check if you have them like this. To run on normal cpu cores, use taskset -c 8-15 sinol-make ..., assuming that cpu cores 8-15 are not efficiency cores. Run sinol-make run --help to see available flags.
• sinol-make gen -- Generate input files using ingen program (for example prog/abcingen.cpp for abc task). Whenever the new input differs from the previous one, the model solution will be used to generate the new output file. You can also specify your ingen source file which will be used. Run sinol-make gen --help to see available flags.
• sinol-make ingen -- Generate input files using ingen program (for example prog/abcingen.cpp for abc task). You can also specify your ingen source file which will be used. Run sinol-make ingen --help to see available flags.
• sinol-make outgen -- Generate output files using the model solutions. Run sinol-make outgen --help to see available flags.
• sinol-make inwer -- Verifies whether input files are correct using your "inwer.cpp" program. You can specify what inwer program to use, what tests to check and how many CPUs to use. Run sinol-make inwer --help to see available flags.
• sinol-make export -- Creates archive ready to upload to sio2 or szkopul. Run sinol-make export --help to see all available flags.
• sinol-make doc -- Compiles all LaTeX files in doc/ directory to PDF. Run sinol-make doc --help to see all available flags.
• sinol-make verify -- Verifies the package. This command runs stress tests (if available), verifies the config, generates tests, generates problem statements, runs inwer and run all solutions. Ingen and inwer are compiled with address and UB sanitizers. Run sinol-make verify --help to see all available flags.
• sinol-make chkwer -- Run checker with model solution and print results. Prints a table with points and checker's comments. This command fails if the model solution didn't score maximum points. Run sinol-make chkwer --help to see all available flags.
• sinol-make init [id] -- Creates package from template on github and sets task id to provided [id]. Requires an internet connection to run.

You can also run multiple commands at once, for example:

sinol-make gen prog/abcingen2.cpp inwer --cpus 4 run --tests abc1*.in doc export --no-statement

There are also available short aliases for the commands:

• sinol-make r for sinol-make run
• sinol-make g for sinol-make gen
• sinol-make i for sinol-make inwer
• sinol-make e for sinol-make export
• sinol-make d for sinol-make doc
• sinol-make v for sinol-make verify
• sinol-make c for sinol-make chkwer
• sm for sinol-make

Contest types

sinol-make changes its behavior depending on the contest type specified in config.yml. You can specify the contest type with the sinol_contest_type key in config. Here is the table of available contest types and their features:

Feature	default	oi	oij	icpc
