# Settings and Environment Variables

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.

  // Keeps the variables in initializers before lifting variables (when
  // `lift_variables == true`) or newly adding variable initialization patterns

  // may unexpectedly also remove the initialization patterns for non-variable

    avoid repeatedly formatting variables back and forth. The desired formatting
    is determined by TPU program compilation, so this pass does not include how
    to reformat the variables, but only inserts general TPUReshardVariablesOps in
    proper places, and TPUReshardVariablesOps interpret the compilation.

    The core idea of this optimization is to keep track of the formatting state

// iteration and possibly observe the wrong value of the variable.
//
// Note: An iteration variable can only outlive a loop iteration in Go versions <=1.21.
// In Go 1.22 and later, the loop variable lifetimes changed to create a new
// iteration variable per loop iteration. (See go.dev/issue/60078.)
//
// In this example, all the deferred functions run after the loop has
// completed, so all observe the final value of v [<go1.22].

// Expose higher level temporary variable operator for Pluggable vendors to

// the context with indices for the input and variable name. This function will
// return an error when either of the following conditions is met:
//   1. `input data type` is not ref type
//   2. Cannot find temporary variable by name in arguments
