CLI

Run code

Give a file and a language; get back just the program's output.

Run a local file

No sandbox to create or manage. The language is an id or a code — both work.

shell

boltz run --language python main.py
boltz run --language 100 main.py

Run inline code

shell

boltz run --language python -c "print(1 + 1)"

Judge a solution

Test input, the expected answer, and the problem's limits. The exit status is the verdict: 0 when it is Accepted, 1 for a wrong answer, a time limit or a compile error, and the program's own code when it exits non-zero.

shell

boltz run --language python solution.py \
  --stdin input.txt --expected output.txt \
  --time-limit 1s --memory-limit 64

boltz run --language cpp solution.cpp --stdin - < input.txt   # stdin from a pipe

Time and memory

shell

boltz run --language python main.py --stats
# (Accepted · 0.012s CPU · 0.015s wall · 9216 KB)

The full response as JSON

--json prints the whole result — status, time, memory, stdout, stderr, compile output — exactly as the HTTP API returns it.

shell

boltz run --language python main.py --json
