Running code in a Tarantool instance

$ tt run [SCRIPT|-e EXPR] [OPTION ...]

Options

-e EXPR, --evaluate EXPR¶

Execute the specified expression in a Tarantool instance.

-l LIB_NAME, --library LIB_NAME¶

Require the specified library.

-i, --interactive¶

Enter the interactive mode after the script execution.

-v, --version¶

Print the Tarantool version that is used for script execution.

Details

tt run executes arbitrary Lua code in a Tarantool instance. The code can be provided either in a Lua file, or in a string passed after the -e/--evaluate flag. When called without arguments or flags, tt run opens the Tarantool console.

If libraries are required for execution, pass their names after the -l/--library flag.

By default, a Tarantool instance started by tt run shuts down after code execution completes. To leave this instance running and continue working in its console, add the -i/--interactive flag.

Examples

• Execute the app.lua file in a Tarantool instance:

  $ tt run app.lua
  

• Execute an expression in a Tarantool instance:

  $ tt run -e "print('hi there')"
  

• Execute the app.lua file in a Tarantool instance and leave it running:

  $ tt run -i app.lua
