Refactor some environment code into env_dispatch.cpp This new file is supposed to encapsulate all of the logic around reacting to variable changes, as opposed to the environment core. This is to help break up the env.cpp monolith. 2019-03-26 03:18:00 +00:00			`// Prototypes for functions that react to environment variable changes`

Migrate some env initialization into env_dispatch 2019-04-01 02:51:08 +00:00			`class environment_t;`
Try to rationalize universal variable syncing Prior to this commit, setting a universal variable may trigger syncing against the file which will modify other universal variables. But if we want to support multiple environments we need the parser to decide when to sync uvars. Shift the decision of when to sync to the parser itself. When a universal variable is modified, now we just set a flag and it's up to the (main) parser when to pick it up. This is hopefully just a refactoring with no user-visible changes. 2022-03-28 01:59:34 +00:00			`class env_stack_t;`

Remove the op from env_dispatch Environment dispatch passes strings like "ERASE" and "SET" but nobody ever looks at those. Just get rid of them. 2019-04-08 19:37:38 +00:00			`void env_dispatch_var_change(const wcstring &key, env_stack_t &vars);`

Implement (but do not yet adopt) Environment in Rust This implements the primary environment stack, and other environments such as the null and snapshot environments, in Rust. These are used to implement the push and pop from block scoped commands such as `for` and `begin`, and also function calls. 2023-04-30 02:58:51 +00:00			`/// FFI wrapper which always uses the principal stack.`
