# Stack configuration for proxy-tool.
#
# lts-24.46 pins GHC 9.10.3 and supplies every dependency, including the
# Windows terminal backend (brick -> vty-crossplatform -> vty-windows).
snapshot: lts-24.46

packages:
  - .

# Why "$everything: -w".
#
# GHC writes its diagnostics with U+2022 bullets and U+2018/2019 smart quotes.
# Stack reads a dependency's compiler output and re-emits it on its own stderr,
# which is encoded with the machine's ANSI code page.  On a Windows box whose
# code page cannot represent those characters (936/GBK here, but 1252 has the
# same hole), that re-emission throws
#
#     <stderr>: commitAndReleaseBuffer: invalid argument
#               (cannot encode character '\8226')
#
# and the whole build plan aborts partway through -- in this project's case
# while compiling vty, whose -Wx-partial warning happens to contain a bullet.
#
# Warnings from snapshot packages are not actionable here, so turning them off
# removes the offending text at its source and makes the build deterministic
# regardless of the host code page.  The per-package entry below then puts the
# full warning set back for this package's own code, because package-specific
# options are applied after "$everything".
