Isolate tests from user config (#12437)
# Description This is an attempt to isolate the unit tests from whatever might be in the user's config. If the user's config is broken in some way or incompatible with this version (for example, especially if there are plugins that aren't built for this version), tests can spuriously fail. This makes tests more reliably pass the same way they would on CI even if the user has config, and should also make them run faster. I think this is _good enough_, but I still think we should have a specific config dir env variable for nushell specifically (rather than having to use `XDG_CONFIG_HOME`, which would mess with other things) and then we can just have `nu-test-support` set that to a temporary dir containing the shipped default config files. # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` |

IO and redirection overhaul (#11934)
# Description The PR overhauls how IO redirection is handled, allowing more explicit and fine-grain control over `stdout` and `stderr` output as well as more efficient IO and piping. To summarize the changes in this PR: - Added a new `IoStream` type to indicate the intended destination for a pipeline element's `stdout` and `stderr`. - The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to avoid adding 6 additional arguments to every eval function and `Command::run`. The `stdout` and `stderr` streams can be temporarily overwritten through functions on `Stack` and these functions will return a guard that restores the original `stdout` and `stderr` when dropped. - In the AST, redirections are now directly part of a `PipelineElement` as a `Option<Redirection>` field instead of having multiple different `PipelineElement` enum variants for each kind of redirection. This required changes to the parser, mainly in `lite_parser.rs`. - `Command`s can also set a `IoStream` override/redirection which will apply to the previous command in the pipeline. This is used, for example, in `ignore` to allow the previous external command to have its stdout redirected to `Stdio::null()` at spawn time. In contrast, the current implementation has to create an os pipe and manually consume the output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`, etc.) have precedence over overrides from commands. This PR improves piping and IO speed, partially addressing #10763. Using the `throughput` command from that issue, this PR gives the following speedup on my setup for the commands below: | Command | Before (MB/s) | After (MB/s) | Bash (MB/s) | | --------------------------- | -------------:| ------------:| -----------:| | `throughput o> /dev/null` | 1169 | 52938 | 54305 | | `throughput \| ignore` | 840 | 55438 | N/A | | `throughput \| null` | Error | 53617 | N/A | | `throughput \| rg 'x'` | 1165 | 3049 | 3736 | | `(throughput) \| rg 'x'` | 810 | 3085 | 3815 | (Numbers above are the median samples for throughput) This PR also paves the way to refactor our `ExternalStream` handling in the various commands. For example, this PR already fixes the following code: ```nushell ^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world" ``` This returns an empty list on 0.90.1 and returns a highlighted "hello world" on this PR. Since the `stdout` and `stderr` `IoStream`s are available to commands when they are run, then this unlocks the potential for more convenient behavior. E.g., the `find` command can disable its ansi highlighting if it detects that the output `IoStream` is not the terminal. Knowing the output streams will also allow background job output to be redirected more easily and efficiently. # User-Facing Changes - External commands returned from closures will be collected (in most cases): ```nushell 1..2 | each {|_| nu -c "print a" } ``` This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n" and then return an empty list. ```nushell 1..2 | each {|_| nu -c "print -e a" } ``` This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used to return an empty list and print "a\na\n" to stderr. - Trailing new lines are always trimmed for external commands when piping into internal commands or collecting it as a value. (Failure to decode the output as utf-8 will keep the trailing newline for the last binary value.) In the current nushell version, the following three code snippets differ only in parenthesis placement, but they all also have different outputs: 1. `1..2 | each { ^echo a }` ``` a a ╭────────────╮ │ empty list │ ╰────────────╯ ``` 2. `1..2 | each { (^echo a) }` ``` ╭───┬───╮ │ 0 │ a │ │ 1 │ a │ ╰───┴───╯ ``` 3. `1..2 | (each { ^echo a })` ``` ╭───┬───╮ │ 0 │ a │ │ │ │ │ 1 │ a │ │ │ │ ╰───┴───╯ ``` But in this PR, the above snippets will all have the same output: ``` ╭───┬───╮ │ 0 │ a │ │ 1 │ a │ ╰───┴───╯ ``` - All existing flags on `run-external` are now deprecated. - File redirections now apply to all commands inside a code block: ```nushell (nu -c "print -e a"; nu -c "print -e b") e> test.out ``` This gives "a\nb\n" in `test.out` and prints nothing. The same result would happen when printing to stdout and using a `o>` file redirection. - External command output will (almost) never be ignored, and ignoring output must be explicit now: ```nushell (^echo a; ^echo b) ``` This prints "a\nb\n", whereas this used to print only "b\n". This only applies to external commands; values and internal commands not in return position will not print anything (e.g., `(echo a; echo b)` still only prints "b"). - `complete` now always captures stderr (`do` is not necessary). # After Submitting The language guide and other documentation will need to be updated. |

remove stdlib logging env variables (#12196)

Implement annotations support in test runner (#9406)
<!-- if this PR closes one or more issues, you can automatically link the PR with them by using one of the [*linking keywords*](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword), e.g. - this PR should close #xxxx - fixes #xxxx you can also mention related issues, PRs or discussions! --> # Description Test runner now uses annotations instead of magic function names to pick up code to run. Additionally skipping tests is now done on annotation level so skipping and unskipping a test no longer requires changes to the test code In order for a function to be picked up by the test runner it needs to meet following criteria: * Needs to be private (all exported functions are ignored) * Needs to contain one of valid annotations (and only the annotation) directly above the definition, all other comments are ignored Following are considered valid annotations: * \# test * \# test-skip * \# before-all * \# before-each * \# after-each * \# after-all # User-Facing Changes <!-- List of all changes that impact the user experience here.

std: refactor test-runner to no longer require tests to be exported (#9355)
# Description Test runner now performs following actions in order to run tests: * Module file is opened * Public function with random name is added to the source code, this function calls user-specified private function * Modified module file is saved under random name in $nu.temp-path * Modified module file is imported in subprocess, injected function is called by the test runner # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> * Test functions no longer need to be exported * test functions no longer need to reside in separate test_ files * setup and teardown renamed to before-each and after-each respectively * before-all and after-all functions added that run before all tests in given module. This matches the behavior of test runners used by other languages such as JUnit/TestNG or Mocha # Tests + Formatting # After Submitting --------- Co-authored-by: Kamil <skelly37@protonmail.com> Co-authored-by: amtoine <stevan.antoine@gmail.com> |

Logger constants refactored, format argument added, better formatting of failed (non) equality assertions (#9315)
# Description
I have (hopefully) simplified the `log.nu` internal structure and added
customizable log format for all `log` commands
# User-Facing Changes
- [x] Replaced constants with env records for:
- ansi (newly added)
- log level
- prefix
- short prefix
- [x] Added `format` argument to all log commands
- [x] Assertions for (not) equality (equal, not equal, greater,
lesser...) now put left and right values inside `'` quotes, so the
assertions for strings are more meaningful
- [x] Documented the %-formatting of log messages
# Tests + Formatting
