Sander van Dragt's Notes

@

Any developers using bash/zsh shell and git can use this code snippet to effectively git fetch when entering a directory:

function chpwd {
  GIT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)

  if [ -n "$GIT_ROOT" ]; then
    FETCH_STAMP_FILE="$HOME/.cache/chpwd_git_fetch_$(echo "$GIT_ROOT" | tr '/' '_')"
    if [ ! -f "$FETCH_STAMP_FILE" ] || [ $(find "$FETCH_STAMP_FILE" -mmin +10) ]; then
      ({ git fetch --all --quiet && touch "$FETCH_STAMP_FILE"; } > /dev/null 2>&1 &)
    fi
  fi
}

This snippet acts like a lightweight background updater, seamlessly integrating with your shell navigation to keep your local metadata fresh, reduce manual fetches and out of date merges. #til

  • #til In #Godot when you attach a node with a scale as a child of one that doesn't support scale (Node vs Node2D for example), there is a flicker as the card is rescaled. Convert the node to a scale supporting type to fix this.

  • #til In Godot, if a scene is instantiated at design time and a child is added to it, does the child belongs to the scene whose tree is currently open, or the scene it's attached to?

    When duplicating a node (including a scene) at runtime it is the node tree where the node sits that is duplicated, so it includes the child. But if the scene is marked as a InstancePlaceholder, and create_instance() is called at runtime, it creates a instance of the scene, and any attached children have to be duplicated and attached to the instance with code. #Godot
