Hello!
The current shell is pretty for copy-paste operations but the
scrolling through recent command history is useful for interactive
using.
Here is the update for JavaScript function, which allows such
scrolling up and down as in a standard shell. Instead of command
completion it shows possible variants in the output.
Massimo, you can use it in the release if you want.
For others - just replace the single function in
/web2py/applications/admin/views/shell/index.html with this.
==========code of script==============
$('#statement').keyup(function(event){
var t=$('#statement');
var s=t.val()
var o=$('#output')
if(s=='\n') t.val('');
if(s.length>1 && s.substr(s.length-1,1)=='\n' && s.substr
(s.length-2,1)!=':' &&
(s.indexOf(':\n ')<0 || s.substr(s.length-2,1)=='\n')) {
t.val('');
$.post("{{=URL(r=request,f='callback',args=app)}}",
{statement:s},function(data){o.html(o.html()+data).attr
('scrollTop',o.attr('scrollHeight'));});
} else { };
if(event.keyCode==38){
var i=s.length
if(i==0){
var s=o.find('table:last pre:first').text();
bShellScrolling=o.find('table').length;
}else if(bShellScrolling){
var i=bShellScrolling
if(i<1){
return
