Re: [Bug-apl] location of cursor on new apl session

[Juergen Sauermann]

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. After that all user input is entered at the bottom of the screen. This is more portable than grabbing the input at the middle of the screen because you can do it without ESCape sequences for cursor positioning. Everything is based on the ASCII characters CR, LF, and Backspace, wehich are more portable than ESC sequences.  It also works better in scripts and pipes, eg. for web interfaces, and with virtual terminals like xterm. /// Jürgen On 01/27/2017 11:56 PM, enz...@gmx.com wrote: In all my previous apl installations the cursor in an xterm was at the top of the xterm - it stays there for 1.3 but with 1.6 and now 863 i can see it start at the top when first opened but then goes to the bottom and indents - any ideas? I have 1.3 1.6 and 863 all installed on same computer
