Fix the "eval" error due to empty lines in the INI file

[milanbalazs]

Why:

If there is empty trailing line in the INI file you can get the following error:

eval: line 64: syntax error near unexpected token `}'

Solution:

• My change removes the empty lines from INI file.

My test INI file:

# This config file is used for testing

[SERVER]
user            = user
pws             = password

My test code:

#!/bin/bash -e

SCRIPT_FULL_PATH=$(readlink -f "${BASH_SOURCE[0]:-${0}}")
SCRIPT_DIR_PATH="${SCRIPT_FULL_PATH%/*}"

source "${SCRIPT_DIR_PATH}/bash_ini_parser.sh"

cfg_parser "${SCRIPT_DIR_PATH}/configs/servers.ini"

echo "DONE"

Test run without my change (With an extra echo):

 >>> ./test.sh 

}
cfg_section_SERVER () {
cfg_unset SERVER
user=( user )
pws=( password )
}
/home/milanbalazs/scripts/bash_ini_parser.sh: eval: line 65: syntax error near unexpected token `}'

Test run with my change (With an extra echo):

>>> ./test.sh 
cfg_section_SERVER () {
cfg_unset SERVER
user=( user )
pws=( password )
}
DONE

Conclusion:

• As you can see above my change solves the wrong and unnecessary } character beginning of the structure of eval function.
