digitalmars.D.announce - Descent 0.5.4 released

reply Ary Borenszweig <ary esperanto.org.ar> writes:
The Descent plugin for Eclipse provides an IDE for writing, launching 
and debugging code in D.

Explanations on how to get it from within Eclipse are here:

http://www.dsource.org/projects/descent

New features:
  - Compile-time view (Window -> Show View -> Other -> D -> Compile-time 
View): allows you to see things from the compiler point of view, which 
applies some transformations to the source code. For example you can see 
what happens when you do a foreach, when you invoke an "extension 
method", when you do operator overloading; know what type has an auto 
variable; how struct fields are accessed?; compiler optimizations. It 
also removes conditionals that evaluate to false, and shows the results 
of mixins in-place. As always, this is far from perfect and a lot of 
things can be improved. For the lazies, I'll later upload a video about 
this. :-)
  - Now hovering over a mixin (over the "mixin" keyword) shows it's 
result in a popup.
  - Now hovering over a function or template instance with ctrl+shift 
shows it's compile-time result (with shift only: it's source code).
  - Added code templates for operator overloading, so that you don't 
have to remember all those names. Try them by typing "op" and pressing 
ctrl+space.

(when available) are shown for classes. "ptr" and "funcptr" are shown 
for delegates.

Please note that most of these features are experimental. (the 
compile-time view is mostly useful to experiment with small cases to see 
what the compiler is doing, like for example if you write "auto x = [1, 
2, 3];", to see what type the compiler gives to x)

I also fixed the problem with the last version: I accidentally 
introduced a dependency with JDT and that was causing the problems most 
of you had, so in this version this dependency was removed and updating 
should work as usual.

Any suggestion, critic or bug report is welcome. You can use:
- the forums: http://www.dsource.org/forums/viewforum.php?f=107
- trac: http://www.dsource.org/projects/descent/report?action=new
- irc: at freenode, #d.descent

The compile-time view looks quite useful!
I also really like the autocomplete code snippet for the opApply.  I
always dread having to write those.

By the way, in the vid you use a plain int param in your opApply
delegate, instead of "ref int".  I think this will not work.  At least
I seem to remember finding that opApply doesn't work unless I make all
the delegate's arguments ref.

I think some of that came from an auto-complete code template, so if
the code template doesn't include the 'ref' it should, as a hint to
the programmer.

Another question -- I was wondering what it does for CTFE functions.
I'm guessing it evaluates them and spits out the result.  If so that
could be very very helpful.  Especially for code-building CTFE mixins.
 I don't think you had an example like that in the vid.

This compile time view could be a great debugging and learning aid for
D.  I think it's quite exciting.  I wonder if someone can get it
working on something like http://paste.dprogramming.com/

Yeh, web.  There's already a site where you can paste in D code and
the server will compile and run the code for you.  A compile-time view
button on that page would be great.  Not that you should be the one to
do it or anything.  Just thinking it would be nifty, that's all.

Great observation! I remember functions like that not being evaluated 
unless the variable was declared const. I just debugged that and checked 
with DMD's source code, and it seems the expression in the initializer 
is evaluated if the variable declaration is not inside a function (check 
VarDeclaration::semantic2 and ExpInitializer::semantic, which invoked 
optimize at the end).

I wonder why is that behaviour defined like that...

Because then it's a static global. And static initializers get run at 
compile time.

I've found one limitation of this, and it's a really weird one.  It

I've attached the smallest test case I was able to make; hope it helps,
because this is just about the BEST thing ever.  As someone who makes
heavy use of meta-programming, this is fantastic.

Incidentally, the backtick-quoted string seems to make the editor VERY
confused; try starting a `` literal, and pressing Enter inside.  Now
imagine trying to write a big code mixin like that...

"Module foo has syntax or semantic errors due to mixins".

Cool.  Can I make one other inquiry?  Is it possible to get the CT
window to not scroll back to the top every time the source file changes?
 I've just been using it to debug a mixin (oh God I love this SO MUCH)
and I had to keep scrolling down every time I changed something.

Even if I had to manually pin the window, or specify which part of the
code to view the CT for, it'd really improve the feature.

who said you can't? here's how you can have both:

eclipse (descnet is a plugin of it) has three default key mappings that 
can be used:
  - the default eclipse key bindings
  - emacs key-bindings
  - vim key bindings

besides that there's also a plugin that implements vim for eclipse, 
which I forgot it's name. you can google for it, I guess. the plugin 
integrates vim's text editing capabilities into an eclipse editor.
I didn't try the plugin with D code, but for C/C++ it works great.

and it fails, but it also fails under DMD (1 and 2). If I change the order:

---
char[] defineInt(char[] name) {
	return "int " ~ name ~ ";";
}

mixin(defineInt("bar"));

it works both in DMD and Descent.

Also, I see some istring and cstring. If you are using D2 it is more 
likely that it won't work, because D2 is still not fully ported to Descent.

Furthermore the function is defined in another module and imported. 
mixin is used in the main module.

Which ones are the -O ones? You can see which optimizations are applied 
in the front end in optimize.c

For example this:

---
int foo(int x) {
   return x * 2 * 2;
}

int bar(int x) {
   return 2 * 2 * x;
}
---

is transformed to this:

---
int foo(int x) {
   return x * 2 * 2;
}

int bar(int x) {
   return 4 * x;
}
---

So it seems the optimize.c code just optimizes left subexpressions. I 
wonder if -O does more that. Because if not, there's still a lof of room 
for optimization in the compiler.

Where can I find a version of obj2asm for Windows to see what's going on 
in those cases?

 Since Descent has a Java port of the DMD frontend inside, it probably just 
 runs the semantics passes on the AST and prints it back out...

Erm, the ones I invoke with -O :)
I thought they were seperate from the semantic pass van Bommel mentioned

 New features:
  - Compile-time view (Window -> Show View -> Other -> D -> Compile-time 
 View): allows you to see things from the compiler point of view, which 
 applies some transformations to the source code. For example you can see 
 what happens when you do a foreach, when you invoke an "extension 
 method", when you do operator overloading; know what type has an auto 
 variable; how struct fields are accessed?; compiler optimizations. It 
 also removes conditionals that evaluate to false, and shows the results 
 of mixins in-place. As always, this is far from perfect and a lot of 
 things can be improved. For the lazies, I'll later upload a video about 
 this. :-)
  - Now hovering over a mixin (over the "mixin" keyword) shows it's 
 result in a popup.
  - Now hovering over a function or template instance with ctrl+shift 
 shows it's compile-time result (with shift only: it's source code).


Just a small remark: the probability that these things stop working is 
bigger if the code is spread in many modules. That's because I did some 
optimizations and lazy loading of some symbols, and sometimes it doesn't 
work (I'll fix that, eveeeeeeentualy). So this should work better in a 
single module. That's why this should be a good aid for prototyping new 
functionality that heavily uses mixins, templates and compile-time 
evaluation. :-)

This build is not compatible with Eclipse3.3 und SuseEnt10(SP2) as well.
When I press CTRL+Space, I will see an error message:

----------------------------------------------------------------------------
The 'descent.ui.JavaNoTypeCompletionProposalComputer' proposal computer from
the 'descent.ui' plug-in did not complete normally. The extension has
thrown a runtime exception.

To avoid this message, disable the 'descent.ui' plug-in or disable the
'Other D Proposals' category on the content assist preference page.
----------------------------------------------------------------------------

There is no problem with Windows, but with SuseEnt10.
Is it possible to make it work again??

For more information, please another thread of mine in this group.

Haw haw, that's because the DMDFE replaces symbols it doesn't know
with 1.  That's why the compiler spits out tons of bizarre "expected
function before parens, not '1' of type 'int'" after undefined symbol
errors.  Either you're not importing std.cstream, or Descent isn't
looking it up right.

Hehehe, Jarret is right here!

I've fixed this so that in this case I'll use the original source code 
in the output view.

What do you mean?

I just tried:

---
class Foo(T) {
	
}

void lala() {
	Foo!(int) foo;
}
---

and it was shown like:

---
class Foo(T) {
	
}

void lala() {
	Foo foo;
}
---

(should be Foo!(int))

Is that what you mean?


 3. I have a template (called factory) that takes a string argument.  The
compile time view translates
    alias factory!("libego") gameDef;

Bug. :-)

I've fixed these in a new version, 0.5.4.20090129.

Jarrett's reply makes me realize the issue. I have version(unittest) import
std.cstream;
I thought I told descent to use unittest in its list of versions. I'll double
check my setup.

No :(
Templates are designed to do compile-time magic based on their input arguments.
Currently, I can't see that magic in the compile-time view. The templates I
looked at were still template foo(T) instead of somehow showing the bodies for
foo!(int) and foo!(char)

Thanks for Descent and the rapid fixed!

Unrelated to the new features, I have a few other observations
1. The auto-complete of parenthesis makes me lazy and I end up leaving off
semicolons. Is there any feature to add those too?
2. Auto-complete of curly braces works differently than parenthesis. I usually
type the matching symbol anyway. For parenthesis, everything just works, but I
keep ending up with too many closing curly braces.

I'm very new to descent, so I still have time to correct my own behavior when
editing code.

I can't expand every template instantiation because then it will be a 
mess, and the code formatter also won't work.

You can try pressing ctrl+shift and hovering the template instance. It 
should show you it's content (removing false static ifs and stuff).

Is this what you mean? Can you provide an example?

I have no great example handy, but I tried doing the equivalent of this example
(dmd 2.022):

import std.algorithm;
void main(){
  auto x = sort!("a<b")([2,3,5,4]);
}

Sadly, nothing happens with the ctrl+shift+hover trick.  The compile time view
reports it as missing.  I checked the user libraries to make sure it was ok.  I
have two: druntime and phobos.  The phobos path displays as
usr/local/src/phobos (I navigated to /usr/local/src/phobos through the gui to
select it).  I see the std subdirectory and algorithm.d inside of it.  I don't
know what is going wrong with finding the import.

sort is really a wrapper around sortImpl, which has two bodies inside a static
if.  It's trivial to figure out which one is used, but it'd be nice to have a
way to see what was really done without all the static if's.

I think D2 support is weak in Descent; so that's likely the problem.

 "outer" (when available) are shown for classes. "ptr" and "funcptr" 
 are shown for delegates.

 Please note that most of these features are experimental. (the 
 compile-time view is mostly useful to experiment with small cases to 
 see what the compiler is doing, like for example if you write "auto 
 x = [1, 2, 3];", to see what type the compiler gives to x)

 I also fixed the problem with the last version: I accidentally 
 introduced a dependency with JDT and that was causing the problems 
 most of you had, so in this version this dependency was removed and 
 updating should work as usual.

 Any suggestion, critic or bug report is welcome. You can use:
 - the forums: http://www.dsource.org/forums/viewforum.php?f=107
 - trac: http://www.dsource.org/projects/descent/report?action=new

 Enjoy!


 Since the version 0.5.4.20090129 is available through the update 
 manager  updating fails with:

 An error occurred while collecting items to be installed

 i think the feature.xml inside the updated plugin package needs to be 
 updated to the new jar files.


 
 Yes, I don't know what happened.
 
 Can you try to update now? I think I fixed it.


works now, thanks.

 New features:
  - Compile-time view (Window -> Show View -> Other -> D -> Compile-time 
 View): allows you to see things from the compiler point of view, which 
 applies some transformations to the source code. 



 It also removes conditionals that evaluate to false, and shows the results 
 of mixins in-place. 


You've sold me. Finally, a reason to use an IDE!
Totally awesome.

Here's a temporary one:

Perhaps the computer he's running Eclipse on doesn't have an internet 
connection?
This way he can download it onto (e.g.) an USB stick and install from there.

Hi,

I just uploaded a new version with some semantic fixes (0.5.4.20090209).

Started my descent quest..
Mostly because I wanted the : Highlighting of all occurrences of the current

Also just to look what else might be interesting.

Had a few problems with descent and PATH. Maybe it was something else but 
could it maybe be that you need to logout for eclipse to see changes in the 
PATH?

Well things seem to be working now but I miss poseidons syntax colourscheme.
Is it possible to have different colours per keyword(group)?

Yes, probably. I'm not sure.

What's a keyword group? You can change the colors, but you'd change all 
of the keywords to another color (except "return": you can color returns 
with a different color, useful to see all exit paths of a function).

I mean log out of XP. Because normally you only need to restart the program.
A well, it works now. I'm happy again :D

Poseidon has 7 (custom) groups of keywords which have different colours.
eg. import=orange, static=green, void=blue, this=purple
To me it makes source much easier to navigate.

It's possible, yes. But I think the code will look like a mess. :-P

I'll need a complete list of the keywords inside each group to do that. 
And... I'm back to university, and work, and in a few days I'm on 
vacations, so... I won't be able to do much.

Me understands..

I could list everything here, but I think it would be easiest to just 
download Poseidon.
That way you can marvel at its highlighting in private.

Honestly I don't know how people can cope with that.. if you use 30
colors, don't they stop having meaning?  :|

Yes, I think the code will look like a mess. But maybe he's talking 
about primitive types with one color, attributes with other, etc. But 
something like:

public static void ... {
}

with three different colors would just call my attention too much and I 
won't be able to focus on the real code. :-P

The worst offender, by far, is the D highlighter for Kate.  It has 24
separate styles for various syntactico-semantic elements, all of which
have different colors by default.  It looks like a rainbow vomited.
It's just so distracting :P

Yeah, but poseidon's style isn't that overloaded. I also prefer its 
syntax highlighting.
