Currently, when pressing Up in the prompt, the immediately previous history entry will be selected.
Rather than using the immediately previous history entry, it should use the previous history entry that starts with the text currently on the prompt.
For example, pressing Up in the following scenario should select the Console.WriteLine entry as it starts with C:
> Console.WriteLine("Hello World")
> var x = 5;
> C|
Essentially, we want the PSReadLine HistorySearchBackward style behavior.
Hello!
When I start CSharpRepl I'm presented with this error:
One or more errors occurred. (Version string portion was too short or too long. (Parameter 'input'))
Attempting to type any character results in this exception:
> Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

However, it works fine on my laptop. A noteworthy difference between the two machines is that my desktop has .NET 6 Preview 4 installed while my laptop does not. Based on the error I'm assuming that's the culprit (something choking on the pre-release suffix?), but I did not have a chance to dig very far so that might be a red herring.
When waf/PrettyPrompt#155 is ready.

Billion dollar exception(NullReferenceException)
Windows specifications:

Steps to reproduce:
Maybe (haven't tried yet but by description looks promising) we should use
CompletionService.ShouldTriggerCompletion
in
PromptCallbacks.OpenCompletionWindowCallback
instead of a custom heuristic from PrettyPrompt.
hello, this project is pretty cool. 🤩
when type in the bottom of terminal, intellisense area is hidden 👇
last
"".Where()
place caret after . and trigger completion list. All listed items miss description.
The reason is that in AutoCompleteService.GetExtendedDescriptionAsync text of completedDocument contains incorrectly completed text like "".WhereWhere(), "".AggregateWhere(), ...
This is a separate issue from #65 because the reasons for it are different.

Dear @waf
I working with project open source in below but it working with python shell ,
https://github.com/chuongmep/CadPythonShell
I have a question, whether we can apply this project to build and upgrade CadPythonShell to support platform C# Shell or not.This project is only in net 4.8 and cannot go higher because the main software dependency they are working on is autocad
I would like to describe it in a little detail. They run in wpf and as a plugin inside an autocad. Any suggestions are greatly appreciated.
My research direction is to use https://github.com/roslynpad/roslynpad to do but I find they have too many bug in libraries, hope to get some advice from you.
How to pass command line arguments to csx file. With dotnet-script I can do dotnet-script myfile.csx -- arg1 arg2. Is this supported in csharprepl? Thanks.
Right now, the prompt is a simple > sign. It'd be nice to support customization of this prompt, either via a command line flag, an environment variable, or both. It should probably support ansi escape sequences for foreground/background colors.
The design of this could conflict with #23
Automatically increase default indentation of new lines with every open {.
This would probably need support from PrettyPrompt.
It should also correctly cooperate with PrettyPrompt's "Smart Home" (waf/PrettyPrompt#38).
When waf/PrettyPrompt#92 is done and used by CSharpRepl configuration we should add an option to disable the current ForceSoftEnter override.
E.g. I want to have it configured the way that Enter is always soft Enter and Ctrl+Enter is always hard Enter.
Nice work!!! I've been waiting for a cross-platform c# REPL, thanks!
A great feature addition would be the ability to "remote console" into running web applications such as is possible with other stack's REPLs (e.g. elixir/erlang). This is very convenient for confirming/tweaking service configurations and executing code for debugging issues. We use this extensively in our phoenix/elixir deployment (with care on production but very helpful for staging too). Obviously this exposes a security risk but can be locked down.
I imagine that the console would run locally and use tcp to send commands and print the results. It would be up to the end-users to ensure secure connections and proper authorization.
The critical piece is that the console should have fun access to the running system and state. Nice-to-haves would be to have access to the IServiceProvider to instantiate instances of services and inspect/set fields/properties or run methods.

Content of runtimeconfig.json:
{

}The problem probably is that there is expected 'framework' instead of actual 'frameworks'.

Hi,
I'd like to have Visual Studio Dark theme highlighting colors here.
I can prepare this but I'm not sure if you would prefer updating DefaultTheme (this would be my choice so familiar colors would be used out of the box) or if you would create new theme besides currently existing Dracula theme.
It'd be nice to have automatic variables that represent previous prompt results.
There are two possible approaches (they aren't mutually exclusive):
Counting Forwards
Count forwards from the start, e.g. line0, line1, line2, etc. We'd probably want to change the prompt from > to lineN > so it's easy to see what a given line would reference. A downside of this is that it's a more complex UI:
line0> 5 + 3
8
line1> 17 * 2
34
line2> line0 + line1
42
Probably want a command line switch to disable this feature, in case people don't want the extra noise.
Counting backwards
Have automatic variables that always represent the previous line, and the line before that (e.g. last, last2, etc).
last variables, the result will be different.I'm currently planning to implement only Counting Forwards
To my knowledge, roslyn scripting does not support dynamically adding to the ScriptGlobals type, so it might be a bit tricky to implement. We'd also want to ensure that these lines show up in intellisense.

I noticed someone else had reported this a few days ago, but their issue was that they were running it on Windows 7. In my case, I am running Windows 10 Build 19043.1237, but also getting this exception.
It was broken (#68) and is fixed but we should add tests for following key-bindings configurations:
--newLineKeys Enter --submitPromptKeys Ctrl+Enter (feature has no effect; Enter is new line always; Ctrl+Enter is submit).last
Write datetime, close completion list, reopen it.
DateTime and probably all items with length <= DateTime length do not have a description.
From a quick look, it looks like infoService.GetQuickInfoAsync in AutoCompleteService.GetExtendedDescription returns null for cursor position at the end of the word.
Would be nice if csharprepl had some configuration file.
Mainly I'd like to be able to configure key mappings. But there is (or will be) much more thing that could be configurable.
Could be probably done similarly like theme json.

E.g.
#r "nuget: PdfSharp, 1.50.5147"

The error should contain available NuGet targets and the current runtime version and explain that there is no compatible target within the package.
So i have built a dll using net5 that contains classes and stuff i needed. The question is how to reference it into my .csx file? I tried this:
#r "../xu-cell-pos.Server/bin/Debug/net5.0/xu-cell-pos.Server.dll"
But it gave me an error:
(3,1): error CS0006: Metadata file '../xu-cell-pos.Server/bin/Debug/net5.0/xu-cell-pos.Server.dll' could not be found
I made sure the relative file path are correct. Also this works on dotnet-script. Thanks.

Hello, first of all, I hope this issue isn't too confusing.
Sometimes I'm working on C# projects where I'd like to use this C# repl on, but that would mean that I'd have to manually reference the right shared framework, nuget dependencies and other project references.
To fix that, I'm basically proposing adding a console option where one or multiple csproj files could be passed and CSharpRepl would resolve the references and everything necessary.
Since MSBuild is a pain, I recommend using https://github.com/daveaglick/Buildalyzer as it lets you get all the required information for this.
I recently reinstalled my vs installation and just noticed that it also removed my net5 installation. I think it would be good to support net6 preview versions too. Thanks.
It was not possible to find any compatible framework version

I have a question, whether it is available if we can use it same console to embed to WPF ?
For a while now, I've been looking at free alternatives to LINQPad and CSharpRepl has always stood out to me for being something very flexible (along with frequent updates), and a thing that I noticed while using this tool recently is the lack of "visually" inspect any arbitrary object, similar to what LINQPad and SharpLab provide.
Below are some examples of what I'm talking about.
Obviously that there are certain things that probably cannot be accomplished inside a terminal, but anything is better than nothing.
Since it came out, I have loved Visual Studio's CSharp Interactive tool and since I discovered that I could run it outside of it I always had csi.exe in the system environment variables
I confess that csharprepl has won it by a lot, because it has managed to have the intellisense that it lacked outside of Visual Studio. Thanks @waf !!
This is not a feature or a bug report per se, it is more of a discussion.
I am not an English speaker and I confess that I almost always forget how to write csharprepl. I compare it with how I ran CSharp Interactive: Win+R -> csi -> ENTER. With only 6 keystrokes I achieved what I wanted, csharprepl by itself is more than 6 keystrokes, which I almost always misspell, so I end up using csi 😫.
Is it possible, at this initial stage of the tool, to change or shorten its name? put a default alias? I've been looking around and I think the dotnet tools don't allow aliases so I'm not very hopeful 😥
Maybe it's just me, so feel free to ignore and close this issue without any problem.
Meanwhile if someone is in the same situation as me, I share my solution:
Using cmd:
csi.cmd file in a folder which path is in the PATH environment variablestart cmd /K csharprepl and savecsharprepl just: Win+R -> csi -> ENTERUsing Windows Terminal
csi.cmd file in a folder which path is in the PATH environment variablewt -w 0 nt csharprepl and savecsharprepl just: Win+R -> csi -> ENTER0.3.5
I am trying to reference nuget packages on linux but often get errors like "Package contains multiple .nuspec files" or sometimes it seems to work but doesn't end up in adding references, like for "Microsoft.EntityFrameworkCore.SQLite".
As an example, if I run csharprepl and try to install "Microsoft.EntityFrameworkCore" it goes fine, then "Microsoft.CodeAnalysis.CSharp.Scripting" fails with the above error. I then have to completely remove cache to proceed. Also restarting csharprepl and trying to reference Microsoft.EntityFrameworkCore that worked before suddenly doesn't and displays the above error.
Create a CHANGELOG.md file to easily know what the new features and bug fixes are in each new release (also you can use github releases)

System.PlatformNotSupportedException: System.Management currently is only supported for Windows desktop applications.

E.g. this code
new System.Management.ConnectionOptions();works while running from console app, but throws if run from CSharpRepl.
System.Management is implemented only for Windows. There are two base versions:
.nuget\packages\system.management\6.0.0\lib\net6.0 (everything throw PlatformNotSupportedException)
.nuget\packages\system.management\6.0.0\runtimes\win\lib\net6.0 (actual win implementation)
I've located loaded assembly after
#r "nuget: System.Management"in temp directory where referenced copy is and it definitely is wrong implementation (=same size as in .nuget\packages\system.management\6.0.0\lib\net6.0).
Use CompletionService.GetDefaultCompletionListSpan for PromptCallbacks.GetSpanToReplaceByCompletionkAsync.

This is quite complex for C# to get right so I would probably remove configurability of this keybinding (via --commitCompletionKeys) and extend current defaults accordingly.
