Mind, I only do this when I use PHP - never had this problem elsewhere, probably because I use less literal strings elsewhere. At any rate, while PHP tends to output fairly good error messages (certainly better than any other "compiler" I've ever used including dmd at the moment, but hopefully not forever(?)) in this case it just cannot figure out the whereabouts of the error, so I usually end up checking ever singly literal string I've written. (I should really run scripts/compile a lot more often, it's a bad habit of mine to write 200-400 lines and *then* sort out all the errors, just to finally find that the logic is broken, and then I can't find it.)

What do you think about some basic features for leds:
-Class navigator (like in Delphi or python IDE)
-Antialias fonts (leds is scintilla based...)
-Differents encodings (UTF8.... I can't write some spanish characters in leds)
...

Now I'm using SciTE for editing D files in linux, because leds is at an earlier stage, but I hope leds will be a standard tool for D programming

Do note, however, that removing reduncancies also increases the probability that a random change won't be detected as an error.  A part of the art of language design is deciding on the correct amount of reduncancy.  In this case Walter decided on a choice that made things easy for the parser.  Many of his choices were made on those grounds.  D is intended to be parseable purely syntactically, without the need for any semantic knowledge, or any non-local knowledge, e.g.

Not necessarily:

	qwert = yuiop
	(asdfg())

would change its meaning from

	qwert = yuiop(asdfg());

to

	qwert = yuiop;
	asdfg();

I think the time spent by the rest of us somehow resolving the resulting ambiguities/syntax errors/bugs would outweigh the benefits.

How, exactly?

Like eclipse class hierarchy?
or a complete hierarchy?

I thing a simple parent hierarchy could be usefull
and simple to implement.

what do you mean? a full classes relation diagram?
(that might not happed soon but should be fun to do
I can imagine a full OpenGL navigation ;)

> -Antialias fonts (leds is scintilla based...)

from Scintilla docs:
"On GTK+ 2.x, either GDK or Pango can be used to display text.
Pango antialiases text and works well with Unicode but GDK is faster.
Prepend a '!' character to the font name to use Pango."

so when leds allows you to select the font that should be covered.

> -Differents encodings (UTF8.... I can't write some spanish characters in leds)

from scintilla:
SCI_SETCODEPAGE(int codePage)
SCI_GETCODEPAGE

but I no nothing about UTF how do you know the codePage number? I'm going to try to add that option right now.

Since I remove the background (separate thread) compile and execute
leds is uncrashable (yea, sure), except for the combo boxes.
I need to reread the GTK threads docs. :(
I need to fix the combo boxes. :(

leds has only 3 combos I'll change that to entries (text fields),
add the code page (help me here with the code numbers),
(maybe not) allow to select the fonts
and release it in a couple of days.

try leds in a few days after the next release announcement.

How can one keystroke in fifty be a big time saver? I still spend much more time typing SPACEs for my indents (still trying to remember to use TAB now that I use editors that will insert SPACEs).

I like the semi-colons, especially when several statements are on one line
(yuck).

Is:

x = y f(z)

two statements? Or did I forget an operator?
If I missed an operator I want the compiler to tell me something's wrong, rather
than hum happily along.
And wouldn't the time spent finding such a bug far outweigh any potential time
saving from not typing that one simple character?

The first programming language I learned was BASIC Plus on a PDP-11, it allowed a colon to separate multiple statements on a line, so the above could be unambiguous as:

x = y : f(z)

(I used to see how few lines I could use for my programs, now I've learned to use as many lines for one statement as possible, especially for .net)

So does nearly every BASIC dialect ever invented.

But probably not what the programmer intended.

Really a complete code navigation
in a Tree view you can put all the classes and functions of the active file (d file)
you can expand the tree and see all the class members (grouped by visibility... public, private....)
double clicking in the tree the current cursor position at the code will be moved member or function you selected.

In this way, you can see al the members class easily and navigate throw the code. I don't know about eclipse but Borland Delphi and python IDE have something there.

The code navigator is really usefull to remember all the functions in a file and all the members for one class

Really full code navigation and one option to open an imported file.... ;)

Ok. really for text editing no need a great speed but the visual aspect is better for antialiases fonts

You can select the encoding you want for the editor....
from SciTE you can select File->Encoding... and select 8 bits, UTF-8.....

Gtk2 uses UTF8 so i use UTF8 for my file encodings (no translating strings)
No need to know codepage.... is character encoding and you can select those you want

Not only combo.....
From DUI TEditableCells.d file

//		columns ~= DUIType.INT;
//		columns ~= DUIType.STRING;
//		columns ~= DUIType.BOOLEAN;

		columns ~= DUIType.STRING;
		columns ~= DUIType.STRING;
		columns ~= DUIType.BOOLEAN;

strange results DUIType.INT is broken....
I get strange results in the Treeviewcolumn......
visual representation for integers converted to strings is bad.... in the window but the stdout is correct

i can red in the terminal screen:

3       bottles of coke true
5       packages of noodles     true
2       packages of chocolate chip cookies      true
1       can vanilla ice cream   true
6       eggs    true

but in the Editable cell example window:

3456789 	bottles of coke
56789		packages of noodles
23456789	packages of chocolate chip cookies
123456789	can vanilla ice cream
6789		eggs


funny...  :)

when i add items clicking button all is ok..... in window and console

there is something wrong in ListRow....

All right... waiting

now i'm working in my PostgreSQL >= 7.4 D interface ..... ;)
can write programs in C stlye....

...

        /* Make a connection to the database */
        conn = PQconnectdb(conninfo);
		if (PQstatus(conn) != ConnStatusType.CONNECTION_OK)
        {
                printf("Connection to database '%s' failed.\n", PQdb(conn));
                printf("%s", PQerrorMessage(conn));
				exit_nicely(conn);

        }
		
		/* Start a transaction block */
        res = PQexec(conn, "BEGIN");
        if (PQresultStatus(res) != ExecStatusType.PGRES_COMMAND_OK)
        {
                printf("BEGIN command failed: %s", PQerrorMessage(conn));
                PQclear(res);
                exit_nicely(conn);
        }
...


and using D classes.....


import dlibpq.connection;
import dlibpq.transaction;
import dlibpq.result;



int main(char[][] args)
{
	Connection C = new Connection("dbname = julio"); // can use  Connection C = new Connection() for defaults
	if (!C.connected())
	{
		printf("No pude conectar a la base de datos julio...\n");
		return 1;
	}

	Transaction T = new Transaction(C, "tra1");

	Result R = T.exec("create table ciudades (nombre varchar(80), poblacion int)");
	if (!R.commandOk)
	{
		printf("error creando tabla: %.*s\n", R.errorMessage());
		T.rollBack();

	}
	else	T.commit();

	delete R;
	T.begin();

	char [] sql = "insert into ciudades values ('Trujillo', 10000);";

	sql ~= "insert into ciudades values ('Huertas', 3000);";
	sql ~= "insert into ciudades values ('Madrid', 5000000);";

	R = T.exec(sql);

	if (!R.commandOk)
	{
		printf("error insertando registros: %.*s\n", R.errorMessage());
		T.rollBack();

	}
	else	T.commit();




	return 0;

that's doable. leds already shows you the members for
and opened module (kind of alpha quality but I'm looking at it).
later I don't really fill the need for it.
You know that you can select any variable on leds and open
the module that defines it's type, right?
(again, kind of alpha quality but I'm looking at it)

done!
already I can feel that the page down/page up it's a bit slower.
of course the non anti-aliasing is still available
it's interesting how pango and gtk do the size differently...

yes, I was talking about leds.
I have I major problem on DUI:
accessing the C structs directly
combo needs it, values for TreeView (tables and trees) needs it...
(combo doesn't work at all on the windows version)

you know about my dpq, right?

http://dpq.sourceforge.net (will redirect to the old page)

that project is on hold because I don't need a DB right now, but when I do I think I'm gonna look into ODBC for PostgreSQL.

as you said... in alpha quality... :) but it's the beginning
some things in leds don't run fine for me may be because i'm using the binary package....
When i try to create a new project, i get a messagedialog with: Unable to load project definition for project. :(

then i can write the specs for the project and compile and make.... but can't save the project itself... so i have to create the project again when i run leds.... :(

I can't fell the difference comparing leds and SciTE (may be computer speed.... don't know) it's quick for both

Yes. i changed some code to run in PostgreSQL 7.4.1
but you need a lot of code for communicating and sending comands to backend.... and some bugs..... :)

every time you execute.... result = exec.exec("FETCH ALL in mycursor");
create a new DPQResult object... (returned by exec.exec....) then you execute
result.clear(); for clear the  PGresult* but the created DPQResult still alive.... then you execute again... result = exec.exec(........ and get a stack of unused objects.....


that's because i wrote a new client interface for my own use (but i'll do it public when i finish it) I have writen it using another concept.... near libpqxx (c++ client interface) but more basic and easy to use, (transactions based). The blocking mode is running ok.... now i'm writing the non blocking mode code

PostgreSQL provides a type 4 JDBC driver. Type 4 indicates that the driver is written in Pure Java, and communicates in the database system's own network protocol. Because of this, the driver is platform independent; once compiled, the driver can be used on any system.

A model for D implementation.
