Nonexisting recent projects are removed form the list
lazarus / 9-Editor

I have the following problem:
When I try to open a nonexisting recent project it gets removed from
the recent list.
The reason for the project being nonexistent is that it is stored on
an unmounted network drive.
Is there a way to prevent the IDE from removing these projects?

1. Open $(LazarusDir)\IDE\MainBase.pas
2. Go to method DoOpenRecentFile
3. Uncomment the following two lines:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i //..{ if
not FileExistsUTF8(AFilename) then begin 
 EnvironmentOptions.RemoveFromRecentOpenFiles(AFilename);}//..4.
Rebuild IDE

Ideally one should add a new checkbox("Keep non existent recent
project files in list")  to Tools->Environment->Files. When checked
the EnvironmentOptions.RemoveFromRecentOpenFiles part of the code is
skipped. Very easy to implement, but somehow I'm under the impression
that it wouldn't be a very popular feature. Basically other then you
no one would use it.

That code does not seem to be executed when opening a project. I have
even aded a message box, but it does not show:



Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TMainIDEBase.DoOpenRecentFile(AFilename: string);begin  ShowMessage
('Will open project');  if
DoOpenEditorFile(AFilename,-1,-1,[ofAddToRecent])=mrOk then   
UpdateRecentFilesEnv  else begin    // open failed    if not
FileExistsUTF8(AFilename) then     begin      // file does not exist
-> delete it from recent file list{    
 EnvironmentOptions.RemoveFromRecentOpenFiles(AFilename);     
UpdateRecentFilesEnv;}    end;  end;end; 
Also, I have added some nonsense in the code, so when I received an
error, I got sure that the mainbase.pas is really compiled.

@CM630: Can you file a bugreport for the feature request to make the
removal optional?
Please explain your use case (disconnected network share).
I don't think you are the only Lazarus user out there that might
welcome such a feature.

I think the right place to look for this is OpenProject() in
SourceFileManager.pas:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   if
Assigned(aMenuItem) and (aMenuItem.Section=itmProjectRecentOpen) then 
begin    // Hint holds the full filename, Caption may have a shortened
form.    AFileName:=aMenuItem.Hint;    Assert(AFileName =
ExpandFileNameUTF8(AFileName),'OpenProject: AFileName is not
absolute.');    if
MainIDE.DoOpenProjectFile(AFilename,[ofAddToRecent])=mrOk then begin 
   AddRecentProjectFile(AFilename);    end else begin      // open
failed      if not FileExistsCached(AFilename) then begin       
EnvironmentOptions.RemoveFromRecentProjectFiles(AFilename);      end
else        AddRecentProjectFile(AFilename);    end;  end  else begin
//...

Actually, you can almost count me in... Except, I moved to a diff
solution.

I have a "project group" with all my "commonly used projects". => So I
no longer depend on "recent projects".
However, I have projects on that list that do temporarily disappear.
(They only exist on some branches in my version control).

"project group" also have a check for non-existence.
But with "open last group on IDE start", those are kept in the list
(and displayed strike-through).
