Extract .nu-env tests and more granularity (#3078 )

The autoenv logic mutates environment variables in the running session as it operates and decides what to do for trusted directories containing `.nu-env` files. Few of the ways to interact with it were all in a single test function. We separate out all the ways that were done in the single test function to document it better. This will greatly help once we start refactoring our way out from setting environment variables this way to just setting them to `Scope`. This is part of an on-going effort to keep variables (`PATH` and `ENV`) in our `Scope` and rely on it for everything related to variables. We expect to move away from setting (`std::*`) envrironment variables in the current running process. This is non-trivial since we need to handle cases from vars coming in from the outside world, prioritize, and also compare to the ones we have both stored in memory and in configuration files. Also to send out our in-memory (in `Scope`) variables properly to external programs once we no longer rely on `std::env` vars from the running process.

Andrés N. Robalino	7dc1d6a350	Extract .nu-env tests and more granularity (#3078 ) The autoenv logic mutates environment variables in the running session as it operates and decides what to do for trusted directories containing `.nu-env` files. Few of the ways to interact with it were all in a single test function. We separate out all the ways that were done in the single test function to document it better. This will greatly help once we start refactoring our way out from setting environment variables this way to just setting them to `Scope`. This is part of an on-going effort to keep variables (`PATH` and `ENV`) in our `Scope` and rely on it for everything related to variables. We expect to move away from setting (`std::*`) envrironment variables in the current running process. This is non-trivial since we need to handle cases from vars coming in from the outside world, prioritize, and also compare to the ones we have both stored in memory and in configuration files. Also to send out our in-memory (in `Scope`) variables properly to external programs once we no longer rely on `std::env` vars from the running process.	2021-02-18 20:24:27 -05:00

Yehuda Katz	d07789677f	Clean up lexer (#2956 ) * Document the lexer and lightly improve its names The bulk of this pull request adds a substantial amount of new inline documentation for the lexer. Along the way, I made a few minor changes to the names in the lexer, most of which were internal. The main change that affects other files is renaming `group` to `block`, since the function is actually parsing a block (a list of groups). * Further clean up the lexer - Consolidate the logic of the various token builders into a single type - Improve and clean up the event-driven BlockParser - Clean up comment parsing. Comments now contain their original leading whitespace as well as trailing whitespace, and know how to move some leading whitespace back into the body based on how the lexer decides to dedent the comments. This preserves the original whitespace information while still making it straight-forward to eliminate leading whitespace in help comments. * Update meta.rs * WIP * fix clippy * remove unwraps * remove unwraps Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com> Co-authored-by: Jonathan Turner <jonathan.d.turner@gmail.com>	2021-02-04 20:20:21 +13:00
