Target single file instead of dir

[TomDeSmet]

It would come in handy to be able to select a single file instead of a whole directory.

We need this very much. Too many files and i get "Maximum call stack size exceeded" error. So i have to move some files at a time to a separate directory to work :(

Here is a hacky bash script to achieve this.

Save it a file like vueclassmigrate.sh and add that to your path.

Usage: navigate to the folder containing the file you wish to migrate. In that directory, call eg.
vueclassmigrate.sh MyComponent.vue

# get the value of the first arg passed in
# if no arg is passed, coerce it into "."
if [ -z "$1" ]; then
  ARG="."
else
  ARG="$1"
fi

# if ARG is ".", then run npx vue-class-migrator migrate -d .
if [ "$ARG" = "." ]; then
  npx vue-class-migrator migrate -d .
else

  # get the current pwd
  ORIGINALPWD=$(pwd)
  
  # if ARG is not ".", then we have been asked to convert a specific file. 
  # first, we copy this file to a temporary directory
  TMPDIR=$(mktemp -d)
  cp "$ARG" "$TMPDIR"

  # then we cd to the temporary directory
  cd "$TMPDIR"

  # then we run npx vue-class-migrator migrate -d .
  npx vue-class-migrator migrate -d .

  # then we print ('cat') the migrated file
  # cat "$ARG"

  # then we pipe the contents of the migrated file to the original file
  cat "$ARG" > "$ORIGINALPWD/$ARG"

  # then we delete the temporary directory
  rm -rf "$TMPDIR"
fi
