Variable key in parse_requirements function should be declared as local #681

Bashly Version

Latest Ruby Gem

Description

The generated parse_requirements function declares the variable key without the local keyword, causing it to pollute the global scope. This leads to unexpected behavior when user scripts use a variable named key and then call another command via run().

Contents of bashly.yml

Reproduction Steps

1. Create a command script that uses a variable named key:

# src/my_command.sh
key="my_value"
echo "Before run: key=$key"
run other_command
echo "After run: key=$key"  # key is now overwritten

2. Generate the script with bashly generate
3. Run the command and observe that the key variable is overwritten after calling run()

Actual Behavior

In lib/bashly/views/command/parse_requirements_while.gtx:4, the variable key is declared without local:

while [[ $# -gt 0 ]]; do
  key="$1"
  case "$key" in

This should be:

while [[ $# -gt 0 ]]; do
  local key="$1"
  case "$key" in

Expected Behavior

The key variable should be local to the parse_requirements function and not interfere with user-defined variables in command scripts.
