Horizontal scrolling jumps

[blakemcbride]

Not a problem. A preference.

When displaying very long lines, the display cuts the line short when the screen length is hit. Good. That's the way I like it.

If you try to scroll horizontally past the max screen width, the screen shifts horizontally so that the long line can be seen. In general, I like this. However, I'd rather it shift one character at a time rather than the larger block shift that it does. The reason is that when it does a large horizontal shift your eye has a hard time syncing with the change. It takes a moment to see where you are. If, however, it shifts horizontally one character at a time, it is easy to follow what is going on. Your mind doesn't get momentarily lost.

I realize this is just a personal preference. Perhaps there can be a configuration option.

Thanks!

This is already configurable in great detail thanks to Scintilla, see SCI_SETXCARETPOLICY. It's not very user-friendly I confess, especially since you have to look into the Scintilla header for the values of CARET_SLOP and other constants. (Although that's actually a Scintilla doc issue - usually they print the raw integers as well.)

For instance to scroll by one character instead of "jumping", try
0ESSETXCARETPOLICY$$$ ($ typed with Escape of course).
If you would like to see a bit of the line following the cursor, set a strict "slop" value, e.g. 10 characters: 10,(1#4)ESSETXCARETPOLICY$$$

You can add these statements in ~/.teco_ini somewhere under the !add! label in the ED hook macro (stuff that gets executed when adding a new buffer to the ring).

Please close this ticket if your question has been answered.

No problem. You can also open discussions.

The value is actually in pixels, which just happens to coincide with characters in the Curses UI. If you want a value that works with both the Curses and GTK UIs, you could write: 33ESTEXTWIDTH$9$*10,(1#4)ESSETXCARETPOLICY$$$
