Completion for dotnet add package doesn't work well

See original GitHub issue

Steps to reproduce

Try to use tab completion in PS (after setting it up) or dotnet complete with partial package name.

If the NuGet API is not suitable for this right now, then I think it should be improved.

For example, when trying to add the package Microsoft.CodeAnalysis.CSharp, I might invoke tab completion at one of the following points:

  • dotnet add package Mic<Tab>
  • dotnet add package Micr<Tab>
  • dotnet add package Microsoft.Cod<Tab>
  • dotnet add package Microsoft.Code<Tab>
  • dotnet add package Microsoft.CodeA<Tab>
  • dotnet add package Microsoft.CodeAnalysis.C<Tab>
  • dotnet add package Microsoft.CodeAnalysis.CS<Tab>

Expected behavior

Since package names are hierarchical by convention, tab completion should guide me to the package I’m looking for, word by word, based on the prefix I’ve already typed. In cases when there’s ambiguity, the output should not unnecessarily overwhelm with full package names. At the very least, it should not harm me by completing the wrong package.

Note that I’m using Set-PSReadlineKeyHandler -Key Tab -Function Complete, which overrides the default PS behavior of completing to the first matching value, with bash-like partial completion.

Specifically, what I would ideally expect:

Mic

MicCodes
MicDrop
MickRoper
miCoach
MIConvexHull
MIConvexHullEx

Micro_MVVM
MicroApis
MicroApiService
MicroArgChecker
MicroAssistantDLL
Microbe
MicroBuild
Microbus
MicroCms
MicroComponents
MicroCQRS
Microcrumbs
…

Notice that those are not full package names, just the “segment” before the first . (or possibly also other separators, like -?).

You should use the autocomplete API and not the search API: https://api-v2v3search-0.nuget.org/autocomplete?q=Microsoft.Cod
