yaml multiline strings

[smichel17]

Yaml multiline strings appear to incorrectly drop line breaks in some places. This is important because it limits the ability to embed scripts in a readable manner (there is currently only one way I'm comfortable embedding scripts, and it makes them completely unreadable in the installer). Minimum example:

Add to installer:

- write_file:
    content: '#!/bin/sh

      fullscreen() {
          cd "$gamedir/game"
          ./NecroDancer.sh 1
      }'
    file: $GAMEDIR/run.sh

Expected: Stays the same upon save
Actual: Becomes

- write_file:
    content: '#!/bin/sh

      fullscreen() { cd "$gamedir/game" ./NecroDancer.sh 1 }'
    file: $GAMEDIR/run.sh

Current workaround: Add an extra line break in problematic places (double spaced), like so:

- write_file:
    content: '#!/bin/sh

      fullscreen() {

          cd "$gamedir/game"

          ./NecroDancer.sh 1

      }'
    file: $GAMEDIR/run.sh

The way being block scalars (> or |), and the problem being that they're converted to double-quoted flow scalars with \n for newlines, which results in scripts like this (truncated):

- write_file:
    content: "#!/usr/bin/env sh\n\n# If abi.vsyscall32=0 is already set, no need to\
      \ do anything\nif [ \"$(cat /proc/sys/abi/vsyscall32)\" -eq 0 ]; then\n    exit\
      \ 0\nfi\n\ndialog() {\n    zenity \"$@\" --icon-name='lutris' --width=\"400\"\
      \ --title=\"League of Legends anticheat compatibility check\"\n}\n\nfinal_check()\
      \ {\n    if [ \"$(cat /proc/sys/abi/vsyscall32)\" -ne 0 ]; then\n        dialog\
      \ --warning --text=\"As far as this script can detect, your system is not configured\
      \ to work with League's anticheat. Please verify that you can get into the practice\
      \ too before playing a multiplayer game.\"\n    fi\n}\n\ntrap final_check EXIT\n\
      \nif grep -E -x -q \"abi.vsyscall32( )?=( )?0\" /etc/sysctl.conf; then\n   \
      \ if dialog --question --text=\"It looks like you already configured your system\
      \ to work with League anticheat, and saved the setting to persist across reboots.\
      \ However, for some reason the persistence part did not work.\\n\\nFor now,\
      \ would you like to enable the setting again until the next reboot?\"\n    then\n\
      \        pkexec sh -c 'sysctl -w abi.vsyscall32=0'\n    fi\n    exit 0\nfi\n\

Maybe instead of:

- write_file:
    content: '#!/bin/sh

      fullscreen() {
          cd "$gamedir/game"
          ./NecroDancer.sh 1
      }'
    file: $GAMEDIR/run.sh

One should terminate the lines with commands after them with a semicolon, so they parse correctly? 🤔
Note the semicolon at the cd line, it's unneeded but harmless to add semicolons after every command-line... (See man your shell)

- write_file:
    content: '#!/bin/sh

      fullscreen() {
          cd "$gamedir/game";
          ./NecroDancer.sh 1
      }'
    file: $GAMEDIR/run.sh

This would/should become:

- write_file:
    content: '#!/bin/sh

      fullscreen() { cd "$gamedir/game"; ./NecroDancer.sh 1 }'
    file: $GAMEDIR/run.sh
