13 # DEBUG_FEISTY_MEOW: if this variable is non-empty, then it causes the feisty meow
14 # scripts to print more diagnostic information when they run. not all
15 # scripts support this, but the core ones do.
17 #export DEBUG_FEISTY_MEOW=true
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.
28 NO_REPAIRS_NEEDED=true
30 # check if any crucial folder is hosed. we will torch the existing config
31 # to the extent we can.
32 if [ ! -d "$FEISTY_MEOW_APEX" ]; then
34 unset NO_REPAIRS_NEEDED
35 # wipe out the offending variable(s).
36 unset FEISTY_MEOW_SCRIPTS FEISTY_MEOW_APEX
37 # clean out any unfortunate wrongness that may exist in our generated areas.

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 execute this command:
51 export FEISTY_MEOW_APEX=\$(pwd); echo \"export FEISTY_MEOW_APEX=\$FEISTY_MEOW_APEX\" \> \$HOME/\$USER.fm-fix ; exec /bin/bash -c 'source \$HOME/\$USER.fm-fix; /bin/bash \$FEISTY_MEOW_APEX/scripts/core/reconfigure_feisty_meow.sh ; source \$FEISTY_MEOW_APEX/scripts/core/launch_feisty_meow.sh ; /bin/bash -i --norc --noprofile '
53 Note that this assumes that the .bashrc file could still need editing to fix
54 an erroneous FEISTY_MEOW_APEX variable, so we skip it when bash runs. Check
55 \$HOME/.bashrc to see if a change there will fix the above error.
