PR Summary

Refactor of the file path completion code to make it faster and prepare it for some future improvements I have planned (Not replacing variables in input text, user options for controlling sorting behavior and more).

Speed improvements for relative paths are pretty big:

cd C:\windows\System32\
Measure-Command -Expression {TabExpansion2 -inputScript .\}

old: 1.99 seconds
new: 199 ms

Similar improvements are seen in other providers:

cd HKCU:\SOFTWARE\Classes\
Measure-Command -Expression {TabExpansion2 -inputScript .\}

Old: 1.60 seconds
new: 139 ms

Also stopped it from replacing ~ when referring to home so this: ~\Downloads<Tab> no longer turns into: C:\Users\Martin\Downloads\

PR Context

Fixes #4797
Contributes to: #5350

Not for the PR. Maybe useful .Net implementation pattern https://source.dot.net/#System.Text.RegularExpressions/System/Text/RegularExpressions/RegexParser.cs,151

This PR has 588 quantified lines of changes. In general, a change size of upto 200 lines is ideal for the best PR experience!

Quantification details 

Label      : Extra Large
Size       : +411 -177
Percentile : 86.27%

Total files changed: 4

Change summary by file extension:
.cs : +375 -174
.ps1 : +36 -3

Change counts above are quantified counts, based on the PullRequestQuantifier customizations.

Why proper sizing of changes matters

Optimal pull request sizes drive a better predictable PR flow as they strike a
balance between between PR complexity and PR review overhead. PRs within the
optimal size (typical small, or medium sized PRs) mean:

  • Fast and predictable releases to production:
    • Optimal size changes are more likely to be reviewed faster with fewer
      iterations.
    • Similarity in low PR complexity drives similar review times.
  • Review quality is likely higher as complexity is lower:
    • Bugs are more likely to be detected.
    • Code inconsistencies are more likely to be detected.
  • Knowledge sharing is improved within the participants:
    • Small portions can be assimilated better.
  • Better engineering practices are exercised:
    • Solving big problems by dividing them in well contained, smaller problems.
    • Exercising separation of concerns within the code changes.

What can I do to optimize my changes

  • Use the PullRequestQuantifier to quantify your PR accurately
    • Create a context profile for your repo using the context generator
    • Exclude files that are not necessary to be reviewed or do not increase the review complexity. Example: Autogenerated code, docs, project IDE setting files, binaries, etc. Check out the Excluded section from your prquantifier.yaml context profile.
    • Understand your typical change complexity, drive towards the desired complexity by adjusting the label mapping in your prquantifier.yaml context profile.
    • Only use the labels that matter to you, see context specification to customize your prquantifier.yaml context profile.
  • Change your engineering behaviors
    • For PRs that fall outside of the desired spectrum, review the details and check if:
      • Your PR could be split in smaller, self-contained PRs instead
      • Your PR only solves one particular issue. (For example, don't refactor and code new features in the same PR).

How to interpret the change counts in git diff output

  • One line was added: +1 -0
  • One line was deleted: +0 -1
  • One line was modified: +1 -1 (git diff doesn't know about modified, it will
    interpret that line like one addition plus one deletion)
  • Change percentiles: Change characteristics (addition, deletion, modification)
    of this PR in relation to all other PRs within the repository.

Also stopped it from replacing ~ when referring to home so this: ~\Downloads no longer turns into: C:\Users\Martin\Downloads\

This is an unfortunate change. It's broken me a lot because those tildes not being replaced means that applications no longer understand paths with it in it. I got a suggestion to use Enable-ExperimentalFeature PSNativePSPathResolution but that is apparently no longer an option.

Is there a way for me to turn this back on? I'm getting super tired of having to retype C:\Users\bradwilson. 😢

(If not, I may have to roll back to 7.3.9 indefinitely to preserve my sanity)
