Build

Download and install the latest version of Go.

make
export PATH=$(pwd)/bin:$PATH

Warning: Some tools may not work on Windows. Feel free to open a PR to fix this.

Config

Each tool specifies mandatory config variables. It is not necessary to fill in the others.

Put your config file in OS specific config directory:

  • ~/.config/algolymp/config.json on Linux;
  • ~/Library/Application Support/algolymp/config.json on Mac OS;
  • %APPDATA%/algolymp/config.json on Windows.

Here is an example of a fully filled config:

{
	"ejudge": {
		"url": "https://ejudge.algocourses.ru",
		"login": "<login>",
		"password": "<password>",
		"judgesDir": "/home/judges",
		"secret1": "<random>",
		"uprinter": "Lyceum 9, 3 floor"
	},
	"polygon": {
		"url": "https://polygon.codeforces.com",
		"apiKey": "<key>",
		"apiSecret": "<secret>"
	},
	"system": {
		"editor": "nano",
		"printer": "Samsung SCX-4200"
	}
}

Tip: You will probably need different configs. It's good practice to name them config.json.lksh, config.json.tbank, etc. and create a symlink to config.json.

baron

Ejudge contest users manager.

About

Read user ids from stdin and flip (inverse) their status in Ejudge contest.

This tool has two major disadvantages:

  • It works with ids, not logins;
  • It does not support set operation, only flip.

This is a compromise to not use the Ejudge API for as long as possible based on the idea of compatibility.

Supported modes
  • invis - flip invisible
  • ban - flip ban
  • lock - flip lock
  • incom - flip incomplete
  • priv - flip privilleged
Flags
  • -i - contest id (required)
  • -f - flip mode (required, invis|ban|lock|incom|priv)
Config
  • ejudge.url
  • ejudge.login
  • ejudge.password
Examples
baron --help
cat prizewin.csv | baron -i 48501 -f invis
cat cheaters.csv | baron -i 48600 -f ban
baron -i 56001 -f lock # read from stdin
baron -i 46104 -f incom # read from stdin
baron -i 59000 -f priv <<< admin

fara

Explorer for serve.cfg with mass modify.

About

Fara provides a custom selection language for serve.cfg.

Queries must follow the following structure:

  • .<field> for the root section;
  • @<section>:<id>.<field> for any other section.

The <field> parameter is the name of a configuration variable, such as contest_time in the global section or time_limit in the problem section.

The <section> parameter is the name of a section, such as problem or language.

The <id> parameter is the index (starting from 1) of the object in the specified section, e.g. 1 for the first problem or 3 for the third language.

Parameters <field> and <id> are optional. You can also pass multiple fields or ids, separating them with commas.

If you do not pass -d, -s or -u flags, fara will output the selected fields. Otherwise it will change them and output the resulting serve.cfg.

Some tips for you:

  • Use -q or -q and -d or -q and -u or -q and -s or -q and -u and -s;
  • Select sections in -s mode, selecting fields may end up with strange result;
  • Check the selected fields with -q before changing them;
  • Do not redirect fara output to the same file as input;
  • Check out the examples to learn how best to use this tool.
Flags
  • -q - select queries (required)
  • -d - delete selected fields
  • -u - update selected fields, delete if - passed
  • -s - field to init/overwrite with -u value in selected objects
Config

No config needed.

Examples
fara --help
fara -f /home/judges/048025/conf/serve.cfg -q .score_system,virtual,contest_time
fara -f /home/judges/048025/conf/serve.cfg -q @problem.id,short_name,long_name
fara -f /home/judges/049013/conf/serve.cfg -q @problem.use_stdin,use_stdout -d
fara -f /home/judges/050016/conf/serve.cfg -q @language:2 -d | fara -q @problem:3,4.time_limit -u 15 | bat -l ini

gibon

Polygon API methods multitool.

About

The tool is designed for Polygon API methods outside of the wooda ideology.

Useful when dealing with large size problems, as API methods do not timeout.

The method contest is useful when using scalp or other gibon methods.

Supported methods
  • contest - print problem ids in specified contest
  • commit - commit changes with empty message without email notification
  • download - download the latest (problem revision) linux package
  • package - build full package with verification
  • update - update working copy
Flags
  • -i - problem/contest id (required)
  • -m - method (required)

All methods except contest accept a problem id with -i flag.

Config
  • polygon.url
  • polygon.apiKey
  • polygon.apiSecret
Examples
gibon --help
gibon -i 42619 -m contest
gibon -i 363802 -m commit
gibon -i 363802 -m download
gibon -i 363802 -m package
gibon -i 363802 -m update
for i in $(gibon -i 42619 -m contest); do gibon -i $i -m commit && gibon -i $i -m package; done

pepel

Generate hasher solution based on a/ans/out files.

About

Print python solution that outputs correct answer for each passed input file and failes on any other.

Useful with Polygon to upload a problem without main correct solution.

Make sure your input files has \r\n line endings (use unix2dos), because Polygon works in Windows.

It's ready to work with any input/output files, encoding and escape sequences don't matter.

Works great with wooda.

Please, add a note to the solution in Polygon (e.g. Generated by algolymp/pepel). This will help other problemsetters to avoid misunderstanding.

Flags
  • -i - input files glob (required)
  • -a - answer files glob (required)
  • -z - zlib compression

You should know your shell and probably use -i "<glob>", not -i <glob>.

For large answers, it's strictly recommended to use zlib compression.

Config

No config needed.

Examples
pepel --help
pepel -i "K/*.in.*" -a "K/*.out.*" > pepel.py
pepel -i "tests/*[^.a]" -a "tests/*.a" | bat -l python
pepel -i "*.in.*" -a "*.out.*" -z > pepel-mini.py

postyk

Service for printing Ejudge submits.

About

Daemon that sends user-requested Ejudge submits to the printer. Useful in team contests in ICPC format.

  1. Enable print_just_copy and enable_printing options in your contest.
  2. Share /var/lib/ejudge/cwork directory via url /print/<secret>. Check out the nginx configuration example below.
  3. Set the ejudge.secret1 config parameter to <secret>.
  4. Set the system.printer config parameter to hardware printer name. Leave it empty if you don't need printing.
  5. Set the ejudge.uprinter config parameter to printer. Leave it empty if you use only one printer.

You can find out the printer name by using lsusb on Linux or Get-Printer on Windows.

Flags
  • -i - contest id (required)
  • -t - refresh timeout in seconds (default: 20)
Config
  • ejudge.url
  • ejudge.secret1
