vyuh / SQLITE_CLI_GARBLES_STRINGS.md
Last active November 18, 2016 15:25
Potential Bug Fix: Sqlite CLI removes CR characters in end of line even if they are inside quoted string literals.

BUG

SQLite CLI removes '\r' even from inside quoted strings that appear in SQL input piped into sqlite (CLI). These are never replaced later. A program should not tamper literals in this undocumented way.

DEMONSTRATION

Files in this repository face automatic CRLF translation

Trying to document how I built Elm Platform on FreeBSD 11.1
# make sure lzlib exists on system.
# run `pkg install lzlib`
# this is the only step that required superuser privileges.
# USAGE
# For building at <PREFIX>/Elm-Platform/<VERSION>, run:
# sh build-elm-platform-on-freebsd-11-1.sh <PREFIX> <VERSION>
# SIDE EFFECTS
# Blindly downloads ghc 7.10.2, keeps it beside Elm-Platform in <PREFIX>
