Hi I don't think LineEditContext::adjust_allocated_height() affects where the cursor is places after 'apl' i commented out tons of lines and nothing was effected
i'd like to have the cursor just indented when apl starts in an xterm and no lines entered - i can see the cursor in the xterm right after apl starts but then it moves to last line On Sat, 28 Jan 2017 18:53:38 +0100 Juergen Sauermann <juergen.sauerm...@t-online.de> wrote: > Hi, > > I suppose it is somewhere around LineEditContext::adjust_allocated_height(). > > I wrote my own readline() because the official one caused too many problems > on some platforms. > > If I remember correctly then LineEditContext::adjust_allocated_height() makes > sure that there > are enough empty lines at the bottom of the screen for entering some > (line-wrapped) multi-line input. > > I am not sure what you are after - if it is only not clearing the screen then > you can change the > CLEAR-EOS-SEQUENCE setting in your preferences file accordingly. > > /// Jürgen > > > On 01/28/2017 05:59 PM, enz...@gmx.com wrote: > > with the banner disabled - i don't see apl clearing the xterm screen - if i > invoke apl after using 20 lines (in a 28 line xterm) then apl just starts at > the bottom of the screen - (8 lines below) - i have to clear the screen > (/usr/bin/clear) myself before invoking apl > > when i start apl after 'i clear the screen' i can see the cursor at the top > of the xterm (while the apl loads) and then it moves to the bottom > > Could you give me an idea if you have it on the top of your head where the > code for this is in your code... i will try to find it myself in the > meantime :( > > (i've always been amazed at the complex code you have in your apl just so my > simple apl code will run) </enztec wipes his brown nose> > > > On Sat, 28 Jan 2017 12:57:49 +0100 > Juergen Sauermann <juergen.sauerm...@t-online.de> wrote: > > Hi, > > what you see is the intended behavior. > > When you start GNU APL then the terminal is being reset (clear screen) so > that we can print the > welcome banner.
