# This script looks at the comments on a hasura/graphql-engine-mono issue (or
# pull request) and rewrites all of the benchmark reports to hide them behind
# `<details>` tags. Our goal is to make benchmark reports less noisy on our
# PRs, especially when there are many reports, while retaining the visual
# prominence of the most recent report. To that end, this script is intended to
# be run just before posting a new benchmark report to a PR.
#
# This script depends on the `GITHUB_TOKEN` and `PR_NUMBER` environment
# variables. It identifies a comment as a benchmark report by checking whether
# the comment starts with "## Benchmark Results".
# Get issue comments.
# Note: We currently only fetch the first 100 comments. This may not be
# sufficient in the future.
