如何在Linux中编写文本模式gui？ [关闭]

Question

When I write scripts/programs, often I would like to pop up a simple text 'gui' to prompt for input:

How would I do this? For example from Shell, Ruby, Golang or C. I don't even know what this is called and Google isn't reponding to "text thingy from scripts".

(The example is from the Debian installer).

Answer 1

Actually, that is not dialog, but the newt library (there are a few differences in appearance). It is used by anaconda on Red Hat systems. The whiptail program uses the library, however it has no real relationship to anaconda.

Anaconda is mostly in Python; it uses the newt shared library (written in C) from a Python binding.

For learning it... documentation is largely non-existent. You have the source code.

• newt.git
