This is a developer helper mod. It allows to run any lua code for testing reason. The mod can list and run lua-scripts placed in checks subfolder. Some check scripts are provided with the mod. The second part allows to display global lua-tables variables tree for debugging.

• redirection of print() output to minetest chat
• redirection of print() output to a log file in the world directory. The output is sorted so that it can be compared to find regressions
• robust call of the scripts trough "pcall" does not crash the game in case of syntax- or runtime errors
• all functionality available through chat commands and the QA-Block node
• refresh and list the checks script list at runtime
• edit the code before calling them
• type code and run it
• explore global variables/lua tables

• none
  • smartfs(provided) - GUI for check selection and manipulation. Optional, but without smartfs there is limited functionality

• broken_recipe - Find crafting recipes which require unknown items
• empty - Empty file for your own checks
• get_item_csv - Export all registered items in a .CSV file
• global_variables - List suspicious global variables
• graphviz_recipes_all - Make a graphviz .dot file of all items in a recipe dependency tree
• is_ground_content - This checker lists all nodes for which is_ground_content == true
• list_entities - Lists all the registered entities (except builtin)
• list_spawning_mobs - List entities that are mobs from mobs_redo or compatible framework
• no_doc_items_help - Lists all items without item usage help or long description
• no_item_description - Lists all items without description
• no_sounds - Find nodes that don't have any sounds associated when dug, walked on, etc.
• redundant_items - Lists items which seem redundant
• same_recipe - Find duplicate crafting recipes
• unobtainable_items - Lists items which seem to be unobtainable
• useless_items - Lists all items which are probably useless

add the mod to the game you like to test

• /qa help - print available chat commands
• /qa ls - list all available check modules
• /qa set checkname - set default check
• /qa ui - display and run check using the selection dialog. Browse trough globals (smartfs only)
• /qa checkname - run check
• /qa - run default check

1. get the QA-Block from creative inventory
2. place the block somewhere 3a - without smartfs - wait till the default check is finished and the block disappears 3b - with smartfs - start the check using selection dialog

In all cases - check the debug.txt for test results

• qa_block.print_to_chat, bool. Output QA check messages to chat
• qa_block.log_to_file: bool. Output QA check messages to a file
• qa_block.overwrite_log: bool. Overwrite the file at every game launch
• qa_block.log_date_time: bool. Prepend a date and time stamp to log messages
• qa_block.date_and_time_format: string. Date and time stamp format

• Wuzzy2 - thanks for ideas, code optimizations and most check scripts
• dacmot - for adding output to log file and configuration parameters
