Are there any tools available that allow static code analysis for Free Pascal sources? I would prefer a solution that allows for checking a whole Lazarus project.
Static code analysis is a general technic, not a tool in itself.
the Lazarus IDE contains at least two tools based on static analysis:
the code explorer (symbol list):
the quick syntax checker: Menu, Source: quick syntax check
(this is what is commonly named a linter). But these tools are not available as standalone application.

I need to know when inFullscreen of monitor object is set to true, I wanna make sure it's not set to true when window is maximized. I can't find any docs for imports.ui.main nor any imports.ui.*. That's simple (but still annoying) I can hold alt and press F2 and type lg then enter to try it in the repl. But what if I need some info about queueDeferredWork?
Or what if I wanna know if there's a signal like switch-workspace but when the switch is finished (when switch-workspace is triggered it SEEMS that the switch animation just began and at least inFullscreen doesn't return true when I switch to a fullscreen workspace, it just SEEMS so, I can't make sure as I can't find docs for it.)
Is gnome-shell api (except imports.gi.*) not documented? or am I missing something?
There was very similar question asked here: How do I get the monitor of an active window in GNOME?
Sorry I didn't see your question earlier; you should use the tags [gnome-shell-extensions] and [gjs] to ellicit help for more programming related questions.

As of, well awhile ago, GJS has its own portal for tutorials, documentation and so on.
https://gjs.guide
Everything below is linked to from this portal, so it's a good bookmark.
There are guides covering all the basics, much of the advanced usage, introductions to core libraries like GLib and GTK, including some specialized tutorials like spawning subprocesses. There is also a dedicated section for extensions, covering creation, translations, preferences and porting guides to get your extension working on the latest release.
Please - do request any documentation you find lacking. It may not always be feasible or quick, but we'll do our best.
https://gjs-docs.gnome.org
This is GJS's official API documentation for the GNOME platform, including all core libraries and all the other libraries like GStreamer and WebKit you expect. If a library is missing, you can request it by opening an issue.
For GNOME Shell extensions, these will be of particular interest (see the Architecture page for more details):
Clutter: The compositor-side toolkit, part of Mutter
Meta: The window manager and/or compositor (aka Mutter)
St: Builds on Clutter to add more complex widgets and CSS
Shell: The internal library of GNOME Shell, providing several classes and functions
Gvc: High-level bindings for PulseAudio. Not strictly a part of GNOME Shell, but used by it and worth noting.
This documentation is still correct, however it is probably best for those familiar with the GNOME platform that just need some hints for GJS.
Modules built into GJS: https://gitlab.gnome.org/GNOME/gjs/blob/master/doc/Modules.md
General API usage in GJS: https://gitlab.gnome.org/GNOME/gjs/blob/master/doc/Mapping.md
As JavaScript is (now) evolving fairly quickly, it is highly advised you familiarize yourself with GNOME Shell's JavaScript source. Aside from being crucial to writing extensions, this is the best way to keep up with new features in JavaScript and GJS, including patterns for using them.

I have a large codebase written in assembly that I need to maintain.
Exploring the existing code is tough with text editor's syntax highlighting being the only helping tool.
I was considering to use IDA tool to assist with this task. It has many nice features for exploring assembly code. So I downloaded the free 5.0 version for evaluation.
Unfortunately, I am unable to locate an option that provide the ability to open an assembly source file. All the "open" options do is to dissasmble binaries, but this is useless to me as I already have the source code inclding all the comments and human readable symbols.
It is hard to believe that a tool with so many features lacks this basic capability. So what am I missing here?
IDA, as stated at its website, is a Disassembler. It was developed to find out what a program does WITHOUT the assistance of the source code, not the other way around. Why should anyone try to employ the complex and time-consuming techniques available in IDA to discover what a binary does if all they have to do is take a peek at the original code?
IDA is NOT a development tool, it is a reverse-engineering tool. You should look for an Assembly IDE for the task you seek to complete. Maybe RadASM provides what you are looking for.
I'm new to Chrome Application development and the Native Client/PNaCL pipeline. I'm a bit confused over the process of using existing C code/libraries in a chrome application. The FAQs and NaCL official docs suggest that using existing code is easy, and one of the advantages of developing Chrome applications.
However, there is also mention of nacl-ports, an official list of ported C libraries to be used in Native Client apps.
If I have some random C library I've used, what is the process for actually using it in my Chrome application? This question feels silly, but I'm quite confused over the process. Do I have to recompile the source with a NaCL compiler? Where in the SDK can I find this?
The FAQ also mentions that things like forks, file i/o is not allowed in the library, so I will have to rewrite any code that does these things, is that correct?
Bottomline: I have an existing C library. What is the process for using it correctly, and making calls to it, in a Chrome application?
The short answer is that you'll have to recompile your library with a NaCl C compiler.
You may want to take a look at naclports: this repository contains ports of many common C libraries to Native Client. You can browse the source more easily here.
As for File I/O, we often suggest using the nacl_io library when porting existing code. This provides a POSIX interface (e.g. fopen/fclose/fread, etc.) Many ported libraries require no modifications when using nacl_io.
We're moving to Windows Phone 8. But since many good libraries out there are in pure C. So what is the best way for Windows Phone C# application to consume this C library?
Place C code in WP Static library. Then reference it from WP Runtime
component
Place C code in WP Runtime component
What is the best practice ?
There isn't any real difference between the two approaches. A static library is nothing but a collection of .obj files, the exact same kind of .obj files that you'll get from approach #2. After the linker is done, there won't be any difference in the result.
That's when everything is perfect, an ideal that can be very difficult to achieve when you use open source C code. An advantage of a static .lib is that it improves build time, not having to re-generate the .obj files. But that's also their disadvantage, you'll shoot your foot if you use a .lib that was created by somebody else and he didn't use the same compiler version or compile options. The simplest example of such a trap is building your Debug version and the .lib was built for Release. Or if it uses winapi functions that are verboten in a Phone app, pretty common. So #3 is the best way to avoid problems, build the .lib yourself so you can control all the compile and link settings. Do beware however that it can be very difficult to get open source C code to build, it often comes with a very extensive configuration script, designed to deal with the differences between the many architecture and Unix variants.
I'm looking for a development platform (language and set of libraries) that will allow me to develop a personal project. (In case anyone is curious, I'm looking at making a music library manager, similar to iTunes, that can work on multiple platforms and sync with Android devices).
I want the language to have the following characteristics:
Essential
The program must run flawlessly, with no (or very little) code changes on Mac, Linux, and Windows. That means, notably, that I need to have a cross-platform GUI framework, a consistent API for accessing files and directories, and a consistent interface for talking to USB storage devices
Important
A language that is easy to use, powerful, and expressive. Big standard libraries with a lot of built-in functionality. (I'd probably use C#/.NET but the portability isn't great)
Nice to have
Good tool support (on Linux if possible, but I'll do my development on Windows if needs be)
Not Java. (I have used it and just don't like it - I'm not interested in getting into a language war here).
Please help me choose a language!
Python
Cross platform GUI: more than one option, I'd use WxPython, but Qt bindings are also available (comparison between wxWidgets and Qt).
File System API: this gets into the os package, but there are also convenience methods for just dealing with I/O.
USB I/O: I confess to not having any knowledge here, but suspect if you're talking storage that Python will be able to read and write using its IO package.
Libraries, Ease of Use, etc..: there's a lot built in, but also a huge number of add-ons (called "packages"). Some of the most notable are SciPy and NumPy, used for scientific and numerical analysis.
Tooling: there are a number of IDEs out there, I use PyDev (but it's Eclipse based so you probably won't like it if you don't like Java).
Finally, Python is supported on Android via its scripting environment.
For cross platform GUI, you can explore QT. The back-end can be on c.
Have you explored anything so far?
Qt quick ?
