13 # DEBUG_FEISTY_MEOW: if this variable is non-empty, then it causes the feisty meow

15 # scripts support this, but the core ones do.

21 # this script cannot handle figuring out where it lives, so approaches that
22 # get the WORKDIR will fail. this is a consequence of this always being used
23 # in bash's 'source' directive, which does not pass the script name as
24 # argument 0. instead, we just check for the bad condition of a malconfigured
25 # script system and try to repair it.
27 # we start out thinking things are good.

31 # to the extent we can.

44 The feisty meow configuration is damaged somehow. Please change to the
45 directory where it is stored, e.g.:
47 cd /opt/feistymeow.org/feisty_meow
49 and run this command (the whole unwieldy thing on multiple lines):
52 exec bash -i 3<<EOF 4<&0 <&3
53 echo -e '\n\n^^^ errors above here indicate potential problems in .bashrc ^^^';
54 export FEISTY_MEOW_APEX=\"\$(pwd)\"; export FEISTY_MEOW_SCRIPTS=\$FEISTY_MEOW_APEX/scripts;
55 export FEISTY_MEOW_SHOW_LAUNCH_GREETING=yes;
56 /bin/bash \$(pwd)/scripts/core/reconfigure_feisty_meow.sh;
57 source \$(pwd)/scripts/core/launch_feisty_meow.sh; exec 3>&- <&4
61 Note that this assumes that the .bashrc file could still need editing to fix
62 an erroneous FEISTY_MEOW_APEX variable, so we skip it above when bash runs.
63 Check \$HOME/.bashrc to see if a change there will fix the problem.
