'cd +' adds the ability to revert 'cd -' by having another bounded stack with the same limit for 'redo' actions.
Behaviour is similar to back/forward navigation in explorer.exe
When the location is set to a path and the redo stack is non-empty then the redo stack gets flushed.
When cd + happens, then the redo stack is pushed to as well for a more intuitive way of navigating backwards and forwards.
All the work is done of course on the Set-location cmdlet, which is aliased to cd on all platforms.
* Implement location history feature for Set-Location.
This makes it possible to go back to the last directory using 'cd -',
which is exactly the same syntax as on Linux shells.
* Use an existing stack implementation instead of relying on an environment variable and move logic for 'cd -' into the internal class of SessionState.Path.SetLocation
Keep the (additional) setting of an environment for Unix system in case of mixed usage of cd and Set-Location to provide consistency.
* Use a bounded stack with a limit of 1000 and adapt tests.
Remove setting environment variable on Linux as discussed in PR.
* Fix test: use get-location explicitly to avoid subtle difference in the path string (e.g. an additional slash at the end)
Make syntax to .net call of environment consistent with surrounding code
* Move initialization of _workingLocationHistoryStack into constructor of SessionStateInternal and set the limit to 20 as discussed in PR 5051.
* Make new BoundedStack class in engine utils internal
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
When InitialSessionState initializes it tries to SetLocation to current working directory,
but if the directory name contains PowerShell wildcard characters, it fails and reverts
to $PSHOME.
The change affects Set-Location in that if the path exists (even if containing wildcard characters), just use it. It is a breaking change.
* Fix GetType() bad pattern and related issues in tests
$var.GetType() can raise an exception in tests so we should check $var
before make the call. A large part of the tests does not make this
check.
I start with searching ".GetType()" but discovered many related issues
in tests (reduntant and unneeded tests, "throw" bad pattens, bugs,
formattings (sorry!) and so on) - I had to fix them too.
* Fix after code review
* Second wave of migration GetType() -> BeOfType
Removed 'GetType().Name' patterns.
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
