# DotnetStreams
|
||||
Read text from STDIN regardless of the source.
|
||||
|
||||
## Description
|
||||
This library lets you read text input from STDIN that is entered from the console, piped to the application on the command line without any knowledge of the method. This is useful because you would normally not know if the stream has ended or not and have to check for it differently depending on the source.
|
||||
|
||||
## Consuming the Library
|
||||
|
||||
You can use the library in several ways:
|
||||
- By copying the code to your source repo and adding a project reference to the DotnetStreams project.
|
||||
- By adding a NuGet folder resource to your NuGet sources configuration which points to this project.
|
||||
- By adding a NuGet reference to the DotnetStreams project in the repo at nuget.pillidar.com.
|
||||
|
||||
> **How To Configure NuGet Sources**
|
||||
>
|
||||
> In Visual Studio 2022, right-click the `Dependencies` node in the Solution Explorer for your project. Click `Manage NuGet Packages`. In the upper-right corner, click the cog icon next to the `Package Source` dropdown.
|
||||
|
||||
### Adding a NuGet Folder Resource
|
||||
|
||||
Add a new Package Source.
|
||||
| | |
|
||||
| --- | --- |
|
||||
| Name | DotnetStreams Folder |
|
||||
| Source | C:\dev\DotnetStreams\source\DotnetStreams\bin\Release |
|
||||
|
||||
### Adding a NuGet Repo Reference to nuget.pillidar.com
|
||||
|
||||
|
||||
Add a new Package Source.
|
||||
| | |
|
||||
| --- | --- |
|
||||
| Name | pillidar.com |
|
||||
| Source | https://nuget.pillidar.com/v3/index.json |
|
||||
|
||||
### Adding a NuGet repo at nuget.pillidar.com
|
||||
|
||||
|
||||
## Usage Instructions
|
||||
|
||||
### Consuming Application
|
||||
|
||||
Your console app can use DotnetStreams to enable usage such as these:
|
||||
|
||||
```powershell
|
||||
echo "This is a test." | myconsoleapp.exe
|
||||
```
|
||||
|
||||
```powershell
|
||||
type myfile.txt | myconsoleapp.exe
|
||||
```
|
||||
|
||||
```powershell
|
||||
c:> myconsoleapp.exe
|
||||
line 1
|
||||
line 2
|
||||
|
||||
line 3
|
||||
^Z
|
||||
```
|
||||
|
||||
### Code Usage
|
||||
|
||||
```powershell
|
||||
static void Main(string[] args)
|
||||
{
|
||||
ITextSource textSource;
|
||||
IOutputTarget textTarget = new ConsoleOutputTarget();
|
||||
|
||||
if (args.Length > 0)
|
||||
textSource = new FileTextSource(args[0]);
|
||||
else
|
||||
textSource = new StdInTextSource();
|
||||
|
||||
Execute(
|
||||
textSource,
|
||||
textTarget);
|
||||
}
|
||||
|
||||
public static void Execute(ITextSource source, IOutputTarget target)
|
||||
{
|
||||
source.Open();
|
||||
target.Open();
|
||||
|
||||
foreach (string line in source.ReadAll())
|
||||
target.Output(line);
|
||||
|
||||
target.Close();
|
||||
source.Close();
|
||||
}
|
||||
```
