2018/10/28 06:41 ... Thomas Dickey: Lynx puts blanks at the beginning of each line (except headers, etc) as part of its built-in style. And I was glad when you implemented "NO_MARGINS"-"-nomargins". To me it always seemed backwards that the bulk of the text was indented and the headers were not--no indenting at all seems better than that. ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev

Not in its own right, perhaps. But the underlying cursor-update code (libcurses or whatever it's built with) may well use tabs in order to reduce characters sent to the terminal. (This is a historical relic in many respects, but it still does matter in some cases.) > HTML treats TABs as single SPACEs, right? If so, a browser asserting > one would be un-HTML. You're confusing tabs on _input_ to lynx, from HTML, with tabs on _output_ from lynx, generated by the screen update code. What the outlined problem actually sounds like to me is screen update code that doesn't realize that spaces can have visible attributes. This is a reasonable assumption when attributes are things like "bold" or "italic"; it is not for attributes like "reverse video" or "yellow on blue". This sounds to me like some code thinking that a character cell doesn't need to be updated because it has a space in it and the new character is a space, without noticing that they have visibly different attributes. Unfortunately, if this is what's going on, the relevant code is probably not in lynx, instead being in the underlying screen-update library, and thus not under lynx's control. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev

Lynx puts blanks at the beginning of each line (except headers, etc) as part of its built-in style. curses (or whatever) renders that, but if your terminal description is inconsistent with the terminal, curses will be confused and not repaint parts of the screen. ...if the problem appears in some distribution (versus a self-built kernel), others can comment on the issue -- Thomas E.

Re: [Lynx-dev] What blanks the blank spaces at the beginning of a line?
I'd still like to know where the relevant code is. I looked up 'blank'; the routine in LYCurses.c made no difference. I see likely stuff in GridText.c, but I'm unsure. Retained artifacts are only from the same virtual terminal. If I switch to another VT then back the display is proper. lynx thinks that artifacts are part of the screen: the 'end' key retains artifacts that are below the stuff that's supposed to be displayed. Control-r doesn't fix the display. russell bell ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev
