hac - Helper for Algorithm Competitions

Project description

License PyPI Version PyPI Monthly downloads PyPI Supported Python versions Linux Build status Code Quality

hac is extensible and configurable command-line tool for algorithm competitions. It:

  • prepares directory structures and source files,

  • prepares runner files (scripts used to test solutions),

  • downloads test-cases.

Install

Recommended to install as non-root:

$ pip install --upgrade --user hac

Usage

Example 1

A) For problems “A”, “B” and “C” from Codeforces contest #527 prepare:

  • source file from cpp highest priority template (has lowest X among cpp.X language templates),

  • runner from sh.5 template (interpolated for cpp language template),

  • test-cases downloaded from Codeforces.

$ hac -lcpp -rsh.5 codeforces/527 a b c

With default configuration all of the next lines do same as the one above:

$ hac -lcpp.5 -rsh.5 prep http://codeforces.com/527/A B C
$ hac prep codeforces.com/527 B 1 c
$ hac -d2 CODEFORCES/527 1 2 3
$ hac forc/527 a b c

B) Write solution for problem “B” and test it on test-cases:

$ cd 527/B
$ # ... modify B.cpp
$ ./B.cpp.sh -e  # test solution on test-cases
$ ./B.cpp.sh -c  # clean generated outputs

C) Debug solution for problem “B” on 2nd test-case:

$ ./B.cpp.sh -d 2

Configuration

User specific configuration should be placed in ~/.config/hac directory by default (to change configuration directory you need to set HAC_CONFIG_DIR environment variable).

In order to configure hac according to your preferences:

  1. copy default configuration files in a temporary directory,

$ HAC_CONFIG_DIR=~/temp_config hac --copy-config
  1. customize interesting files in ~/temp_config,

  2. move only customized files to ~/.config/hac, e.g.

$ mkdir -p ~/.config/hac
$ cp ~/temp_config/hacrc ~/.config/hacrc
  1. remove temporary directory.

$ rm -r ~/temp_config

This approach is desirable because only configuration files that differ from the default ones should be present in configuration directory, thereby effectively overshadowing the default configuration.
