Input Reader
May I read what you've written, please?
May I read what you've written, please?
This functionality is an important part of any interactive console application, because it gives users a chance to input what they want to write to the console.
In case you want to listen to mouse events, you can consult the below page:
In case you want to use something other than the reader, you can consult the other input tools defined in the below page:
You can easily use this feature in any interactive console application that uses Terminaux. Just use the Terminaux.Reader.TermReader class that contains the Read() functions and their overloaded versions.
The reader not only provides the static text version for input prompts, but also the dynamic text version. Just create a simple function delegate that generates a string as the first argument, like this:
Please note that they are interruptible by default. If you want the input to be non-interruptible, you can set the interruptible argument to false.
Each one of these functions creates a reader state, TermReaderState, that contains essential information about the current reader state, including, but not limited to:
Current text
Input prompt text
Current text position
Kill buffer
Reader settings
If you're making your own mod in Nitrocid KS, it's best to use its own Input class instead of Terminaux's TermReader, as the class there actually deals with the screensaver in most circumstances.

You can access the global reader settings by referencing the GlobalReaderSettings found in the TermReader class.
You can now set the history entry list with your array of history entries or clear the history list using the following functions:
SetHistory(List<string> History)
Sets the history to the chosen history list
ClearHistory()
Clears all history entries
You can also check to see if the console reader facility is busy getting input or not. The property, Busy, indicates this by returning true if there is input to be entered by the user.
If you want to wait for user input to finish, you can call the WaitForInput() function in the TermReaderTools class.
