I need to parse Delphi .pas files to work with classes with read/write ability. Adding/Modifying/Deleting fields, properties, methods etc. Any idea how to implement this? The implementation is not necessarily in Delphi, scripting languages are also allowed.
There is the Castalia Delphi Parser by Jacob Thurman currently hosted on GitHub.
CnWizards have built-in syntax highlighter so they use some parser too, but I do not remember which exactly. You can look into their sources at https://github.com/cnpack/cnwizards
PasParse is good for you ! Delphi port of the excellent (C#) DGrok.
Delphi 2007 level.

We want to automate OpenOffice, When i search on internet couldnot find a end-to-end help for that and delphi examples are too less. Our intention is to insert document variables and replace the document variable with there values and copying paragraphs etc.
Can any one help me to find an end-to-end help or a pas file like word2000.pas where i can find all the word routines.
Thanks,
Basil
I do use OpenOffice-Automation with Delphi a lot and I think there is no "wrapper" with higher functionality for Delphi.
There is a Delphi OO Project on SourceForge with helpers and examples as a starting point: http://sourceforge.net/projects/ooomacros/files/Delphi%20OOo/Version%201.2/Delphi_OOo_v12en.zip/download
Then you have to study the UNO-API and use COM to call the UNO functions.
You can find a lot of updated information here:

i want my own pascal code to be executed it also have some uses files and other complex functions just like a Delphi code can i do this
Yes:

This component is used in the highly popular Inno Setup installer software.
Delphi Web Script is now under active development again.
Previously it was good; now it is becoming great.
You can download it on Google Code.

Another option, which is useful if you want to support more than just Pascal syntax, would be Fast-Script by the makers of Fast-Report.
There's also paxCompiler
Depends how much pascal you want to interpret. Pascal Script will interpret most stuff but you can't declare classes in a script (You can however import them using script functions). You can't use "uses" clauses either.
If you want to do full on pascal support you're going to have to compile it. You could probably use the FreePascal one providing your app's licensing is compatible (GPL).
TMS has both a scripting engine and a scripting IDE product.
in C# you can easily open an assembly (just another word from an EXE) and then get reflection information from that assembly. I've been looking for something similar for Delphi where I can write a Delphi program that can point to a Delphi EXE then get me reflection information. How can I archive this? Thanks
There are a handful of programs that can extract RTTI from Delphi programs and DLLs. It's not as rich as what's available for .NET, but it can be done to a limited degree. There's a lot more RTTI available in Delphi 2010 and later versions, but as far as I know there's no program out yet that can extract info from them.
I was at the conference where this system was formally announced, and a bunch of people asked how this would affect security. Barry Kelly, who created the new RTTI, said that there would not be enough metadata available to create a "Delphi Reflector".
Well, sad news is, you probably can't. You can easily view .NET assemblies because they a) are compiled to what is called intermediate language (thus you can even get the code back using the likes of Reflector etc.), and b) contain metadata. Delphi, on the other hand, compiles to native code that and produces regular PE files that do not include rich metadata like a .NET assembly.
Delphi just doesn't work that way.
There are tools that can assist in reversing (Delphi written) executables but it will never be easy and it requires good x86 assembly knowledge.
Some examples of such tools are:
IDA Pro and/or Hex Rays
DeDe
Interactive Delphi Reconstructor
PE Explorer
The resource sections of a Delphi Executable also reveals usefull info like the form and it's components.
See also Is there a program to decompile Delphi?
If you have Delphi2010+ you can load a bpl and then use the rich rtti over it lik. e you do with c# and a .net assembly. If you need to do this in a .exe AFAIK you can't.
TestComplete seems to identify most objects in a running Delphi executable. You can extract this information with a script. A demo can be downloaded from http://www.automatedqa.com/downloads/testcomplete
This is maybe not the type of application you want as it is big and made for GUI-testing, but yes it can identify the objects.
As mentioned Remko, IDR (Interactive Delphi Reconstructor) can extract all RTTI information (if program contains it!) for Delphi version from 2 to 2009. Version 2010 will be available later. Moreover IDR can use all information that it finds in program to create a lot of comments to disassemled program code (this is a first step of analyses). You can also look forms and easy go to event hadlers associated with controls.
Any suggestion for a good unicode string library for Delphi 2010? Such thing as class that would contain a collection of independent functions, basically an encapsulation of functions that manipulate strings (ex: Trimlike, Character removal, Positional, Sub-string, Compare, Informational, Case, Replacement, Manipulation functions etc. ).
Thanks
What about SysUtils and StrUtils? They contain many String manipulation functions.
And if those functions aren't enough you could try the JclStrings unit from the JCL - JEDI Code Library (not to be confused with the JVCL - JEDI Visual Component Library).
Mike Lischke has an excellent Unicode library at Soft Gems. It hasn't been updated for Delphi 2009/2010 yet, but it was already working with WideStrings/WideChars, so it should be a pretty trivial port.
I'm using delphi6, and it lacks the following abilities:
a library object,
a list object(looks like TList,TStringList is good enough?)
a algorithm library(like sort,)
template library like STL
dynamic language feature or GC.
and so on.
how can I find this things?
Try Jedi Code Library. There are good replacements for container classes and sorting algorithms. I don't think there is GC or STL-like library for Delphi 6.
Delphi 6 is behind the times, check Delphi 2009 or at least Turbo Delphi
There is DeCAL, which claims to be similar to the STL. I've never really tested it, however.
There are many third party delphi libraries, components and source code examples on the net.
Just a couple off the top of my head
JEDI http://www.delphi-jedi.org/
and
a Delphi super page http://delphi.icm.edu.pl/
As an alternative to DeCAL (Which is a very good alternative to TList without generics), I will propose EZSDL by Julian M Bucknall.
List of main third party components compatible with Delphi 2007 for Win32 and RAD Studio 2007 by Andreano Lanusse at http://edn.embarcadero.com/article/37455
The first three are in the VCL, take a look in the help and the sources. Delphi 6 has no generics, so cannot be used with a template library. And no garbage collection.
If you want to program in Delphi, forget about them. If not, find another language.
