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
fara -f /home/judges/051009/conf/serve.cfg -q @problem:1,4,6 -s use_ac_not_ok | fara -q @problem:1,4,6 -s ignore_prev_ac > /home/judges/051009/conf/serve.cfg
fara -f serve.cfg -q @problem.id && fara -f serve.cfg -q @problem.id -s max_vm_size -u 512M | fara -q @problem.id -s max_stack_size -u 512M > serve.cfg.new

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.

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

ripper

Change Ejudge runs status.

About

Change runs status. Designed to work with boban or with raw ids from stdin.

Be careful using it, double check the parameters.

RJ is reject, not rejudge. Use rejudge status for rejudge.

Flags

• -i - contest id (required)
• -s - new status (required, DQ|IG|OK|PR|RJ|SM|SV|rejudge)

Config

• ejudge.url
• ejudge.login
• ejudge.password

Examples

ripper --help
ripper -i 51023 -s RJ # read from stdin
cat banlist.txt | ripper -i 47110 -s DQ # ban submits with list
boban -i 52010 -f "prob == 'D' && score >= 50" -c 10000 | ripper -i 52010 -s rejudge # rejudge incorrect group
boban -i 50014 -f "login == 'barmaley' && status == OK" | ripper -i 50014 -s SM # torture a participant
boban -i 48001 -f "status == PR" -c 2000 | ripper -i 48001 -s OK # smart code-review

scalp

Set incremental problem scoring using Polygon API.

About

1. Enable problem points;
2. Enable problem groups;
3. Load tests metainfo;
4. Store incremental scoring (0 0 5 5 ... 5 6 6 ... 6) with sum of 100.

Very useful for dumb problems, prepared in ICPC style.

Flags

• -i - problem id (required)
• -s - mark samples as scored tests (put samples in group 0 with 0 score if not set)

Config

• polygon.url
• polygon.apiKey
• polygon.apiSecret

Examples

scalp --help
scalp -i 330352
scalp -i 330328 -s

valeria

Build valuer + textable using Polygon API.

About

1. Get problem tests and groups;
2. Build and commit valuer.cfg (in Ejudge format);
3. Build and print scoring.tex.

Not very fast now, waiting for absentInput parameter in Polygon API.

Thanks to Mike, it's been working fast since 30.01.2024.

Valeria supports several textable types.

• universal - Moscow summer olympiad school format. Works both in PDF and HTML.
• moscow - Moscow olympiads format. Works both in PDF and HTML if no variables are passed, otherwise works only in PDF.

Flags

• -i - problem id (required)
• -v - print valuer.cfg in stderr
• -t - textable type (universal | moscow, default: universal)
• -c - variables list, useful for some textables (default: nil)

Config

• polygon.url
• polygon.apiKey
• polygon.apiSecret

Examples

valeria --help
valeria -i 288808 -v
valeria -i 318511 > scoring.tex
valeria -i 318882 | bat -l tex
valeria -i 285375 -t moscow
valeria -i 285375 -t moscow -c n -c m -c k

wooda

Upload problem files filtered by glob to Polygon using API.

About

Matching uses natural order (test.1.in, test.2.in, ..., test.10.in, ...).

Supported modes

• test - test (append, not replace)
• tags - tags (each tag is on a new line)
• val - validator
• check - checker
• inter - interactor

• ok - correct solution
• incor - incorrect solution
• sample - sample (append, not replace)

Flags

• -i - problem id (required)
• -m - uploading mode (required)
• -g - problem files glob (required)

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

Config

• polygon.url
• polygon.apiKey
• polygon.apiSecret
