Wordwrap content so it'll fit current terminal dimensions?

[asincero]

Is it possible to have pypager word wrap the content being displayed so it'll fit the terminal's current column dimensions? Kind of like how 'less' can.

Hi @asincero,

I'm sorry for the late reply, I just notice this issue right now.
Yes - this should be possible. Prompt_toolkit has the needed line wrapping functionality already implemented. The following patch would always enable line wrapping:

diff --git a/pypager/layout.py b/pypager/layout.py
index 1f09396..c475811 100644
--- a/pypager/layout.py
+++ b/pypager/layout.py

     return Window(
         always_hide_cursor=True,

         content=BufferControl(
             buffer=source_info.buffer,
             lexer=source_info.source.lexer,

Ideally, it should be a boolean configured in _SourceInfo, be off by default and toggleable with some shortcut.

This PR should do it: https://github.com/prompt-toolkit/pypager/pull/9/files
If you have some time, can you try that?
