Re: [Lazarus] Feature Request: more intelligent code completion
Ctrl+Shift+X is a new feature for upcoming 1.8: http://wiki.freepascal.org/Lazarus_1.8.0_release_notes It cannot create properties - neither in the current class nor in a different class. It's a rather easy feature to add because CodeTools already have everything that is needed for it. The "most complex" thing is the dialog - the user needs to choose Getters/Setters and maybe also the ancestor class where to put the property. A handy feature indeed.

Ah, so we learn something new. I didn't know about the interactive one.

Yes. I just tried the interactive code completion now - just to see what it does. It created a public variable bit in the wrong class. It didn't use the BuildProject object, but rather the class I was in. So in this case the generated code also didn't make any sense of leave code that is actually compilable. > It is a half implemented feature.

Well, then maybe introduce another action - an intermediate step that the developer must confirm. Again, Eclipse does this very nicely. It gives a error icon in the gutter (the icon can change to a hint icon for other functionality like possible refactoring suggestions etc). If you click the icon, it presents a list of actions (a keyboard shortcut will show that list as well, so you are not forced to use the mouse). Then simply pick the "Create property in class XYZ..." option. Eclipse goes even further and shows you another window next to the popup window of how the generated code snippet will look like - but this is obviously not needed for Lazarus IDE. I know Eclipse has a massive developer team (compared to Lazarus), and Lazarus can't compete with the amount of features Eclipse has. But allowing Lazarus to generate code that is not even compilable is not acceptable - its a big let down. And as I mentioned, this feature is a massive advantage in Test Driven Development, where you often write the API (method) calls first, then implement them afterwards to resolve the compilation error.

It did correctly deduce the datatype Boolean, did it not? The only missing thing is to place it at the right place, somewhere in TBuildDelphiProjects or its ancestors.

There are currently two code completions: the interactive Ctrl+Shift+X and the non interactive Ctrl+Shift+C. In this case you almost always wants the interactive version.

I have this code:

lFullProjFile: string;

Now the BuildProject class doesn't have a Verbose property. The
TBuildDelphiProjects class does have a FVerbose field of type boolean.
So the data type of FVerbose is known, so to deduce what the missing
property "Verbose"'s data type should be is known (or should be known).
I'm not sure that I want the IDE to modify another class than the one I am
working in at the moment, when I press "code completion" ?
Michael.

[Lazarus] Feature Request: more intelligent code completion
Hi,
I've using the Eclipse IDE for a while now, and the developer is really
spoilt with intelligent code/class completion. I'm wondering if Lazarus
IDE could benefit of some of those features too.
For example - improved (more intelligent) code completion.
I have this code:
==
procedure TBuildDelphiProjects.DoRun;
var
lProjDirName: string;
lDefFile: string; // global defaults INI file
lFullProjFile: string;
begin
CaseSensitiveOptions:=True;
if HasOption('h','help') then
WriteHelp(0)
else if not HasOption('p','project') then
WriteHelp(1)
else
begin
FVerbose := HasOption('V','verbose');
BuildProject.Verbose := FVerbose;// <-- I just typed this.
==
Now the BuildProject class doesn't have a Verbose property. The
TBuildDelphiProjects class does have a FVerbose field of type boolean.
So the data type of FVerbose is known, so to deduce what the missing
property "Verbose"'s data type should be is known (or should be known).
Now if I press Ctrl+Shift+C to code/class complete, Lazarus generates
the following, which has no relevance to what I typed! It doesn't even
solve the compiler error problem.
===
procedure TBuildDelphiProjects.DoRun;
var
lProjDirName: string;
lDefFile: string; // global defaults INI file
lFullProjFile: string;
Verbose: Boolean; // < Lazarus inserted this???
begin
CaseSensitiveOptions:=True;
if HasOption('h','help') then
WriteHelp(0)
else if not HasOption('p','project') then
WriteHelp(1)
else
begin
FVerbose := HasOption('V','verbose');
BuildProject.Verbose := FVerbose;
===
It would have been a lot more logical, and to actually generate
compilable code, if Lazarus prompted me (user configurable) to say that
it wants to implement the missing property "Verbose" for the object
BuildProject (of type TBuildProject). The property simply needs to ask
what visibility do I want the Verbose property... Public of Published
(as TBuildProject is defined in another unit)?
Lazarus (v1.3 and v1.7) generated the same code as show above, and
neither is compilable afterwards! So I don't know what Lazarus was
trying to achieve by introducing that local Verbose: boolean variable.
This is the compiler output I get when I try to compile my project
before and after the code/class completion was triggered.
builddelphiprojects.lpr(79,18) Error: identifier idents no member
"Verbose"
After using Eclipse for some time now, such shortcuts for the developer
is a massive time saver. It also works fantastically well if you do Test
Driven Development. I'm sure Lazarus IDE could benefit from such code
completion improvements too.
I can file this as a feature request on Mantis if need be.

Graeme

As Adrian mentioned, AggPas (native Pascal port of Anti-Grain Geometry) supports SVG and an example is included. fpGUI's repository includes the most up to date (features and bug fixes) implementation of AggPas (that I know of). Lazarus also includes a copy, but it is older that the fpGUI one. And as Adrian mentioned, there is a heavily refactored one called AggPasMod, but I have no idea in what state it is or what bug fixes it had applied to it.
