FAQPage Schema

How do I read user input and write output to the console in Cangjie?▼

Console reading and writing in Cangjie uses built-in functions like println for output and readln for input. You can build interactive programs by prompting users with println and capturing their responses with readln.

What is the best way to log error messages in a Cangjie program?▼

Logging error messages in Cangjie is best done using eprint and eprintln. These functions write directly to the error stream, ensuring your standard output remains clean for regular program data and results.

How do I access stdin, stdout, and stderr streams directly in Cangjie?▼

Direct stream access for stdin, stdout, and stderr in Cangjie is achieved through std.env. This provides ConsoleReader and ConsoleWriter instances, allowing lower-level control over interactive program development and stream operations.

Can I build an interactive command-line calculator in Cangjie?▼

Building an interactive command-line calculator in Cangjie is fully supported. You use readln to prompt users for numbers and println to display the result, while handling potential input errors gracefully through the error stream.

Does Cangjie support separating standard output from error logging?▼

Cangjie supports separating standard output from error logging completely. By using println for standard console output and eprint for errors, you ensure interactive program data and error logs remain distinct.
