I am working on a C/C++ product that only builds in the Linux environment. It is a massive code base and generating lint targets manually is going to be incredibly painful. I know that you can link Lint into cmake so cmake generates these targets for you while it builds the code. Cmake has a macro called add_pc_lint (https://cmake.org/Wiki/PC-Lint) which does this for you. I wanted to know if there is something similar that could be used for Flexelint?
I currently have a PC-Lint license and wanted to ask this question before spending $998 on a Flexelint license. Thanks!
FlexeLint and PC-lint share the same manual so I'm pretty sure they are fully compatible on the command line. You should be able to use the same make files for both, or with minor changes. Otherwise they do offer a 30-day money-back guarantee.
Another option might be to run PC-lint under Wine. I tried this once and I got it working, but then I never used it much so I'm not sure how well it worked.
So I did get a FlexeLint license yesterday and now I am trying to integrate it into my CMakeLists. I am looking at the source code of cmake's add_pc_lint function and trying to modify it to work for FlexeLint. If anyone has played around with it before, please comment. The FlexeLint manual is not at all helpful.

So, there is this cool package I've found but it leaves a lot to be desired. Since it made more sense to modify it, rather than build a new one myself, I changed the code in the corresponding source directory (C:\Users[my username].julia\v0.4[package name]\src). I made sure to modify not just the base.jl file, but also the [name of package].jl one so that there are no issues with dependencies or the new functions I added. I tried running the package several times to ensure that Julia doesn't spit out any errors or exceptions (the original package had some deprecated stuff, which I also remedied). Still, I fail to use the additional functionality of the package that I augmented. Any help would be greatly appreciated.
I'm using Julia ver 0.4.2, on a Windows 7 machine. As an IDE I use Notepad++. Thanks
I'm not exactly sure what you tried, but here's a guess as to what's going on: if you've already loaded the package in your julia session, edits to the source files won't take effect unless you explicitly reload the package. There are some good workflow tips here, and more explanation of the module system here.
However, for a newbie the easiest thing might be to quit julia and restart.
As far as making changes to a package, as Gnumic commented, your best approach is to make a branch and commit your changes there. Once you become convinced your changes represent an improvement, consider sharing your changes with the rest of the world.
Is there a way to run an ant build such that you get an output of what the build would do, but without actually doing it?
That is to say, it would list all of the commands that would be submitted to the system, output the expansion of all filesets, etc.
When I've searched 'ant' and 'test', I get overwhelming hits for running tests with ant. Any suggestions on actually testing ant build files?
It seems, that you are looking for a "dry run".
I googled it a bit and found no evidence that this is supoorted.
Heres a bugzilla-request for that feature, that explains things a bit:
https://issues.apache.org/bugzilla/show_bug.cgi?id=35464
This is impossible in theory and in practice. In theory, you cannot test a program meaningfully without actually running it (basically the halting problem).
In practice, since individual ant tasks very often depend on each other's output, this would be quite pointless for the vast majority of Ant scripts. Most of them compile some source code and build JARs from the class files - but what would the fileset for the JAR contain if the compiler didn't actually run?
The proper way to test an Ant script is to run it regularly, but on a test system, possibly a VM image that you can restory to the original state easily.
Here's a problem: You have target #1 that builds a bunch of stuff, then target #2 that copies it.
You run your Ant script in test mode, it pretends to do target #1. Now it comes to target #2 and there's nothing to copy. What should target #2 return? Things can get even more confusing when you have if and unless clauses in your ant targets.
I know that Make has a command line parameter that tells it to run without doing a build, but I never found it all that useful. Maybe that's why Ant doesn't have one.
Ant does have a -k parameter to tell it to keep going if something failed. You might find that useful.
As Michael already said, that's what Test Systems - VM's come in handy- are for
From my ant bookmarks => some years ago some tool called "Virtual Ant" has been announced, i never tried it. So don't regard it as a tip but as something someone heard of
From what the site says =
"With Virtual Ant you no longer have to get your hands dirty with XML to create or edit Ant build scripts. Work in a completely virtualized environment similar to Windows Explorer and run your tasks on a Virtual File System to see what they do, in real time, without affecting your real file system*. The actual Ant build script is generated in the background."
Hm, sounds to good to be true ;-)
..without affecting your real file system.. might be what you asked for !?
They provide a 30day trial license so you won't lose no money but only the time to have a look on..
After a search here on the forum I found a question like that, and it redirected me to a tutorial which gave em some basic instructions on manipulating SpringBoard with CapitainHook.
To start I'd like to do it with normal %hooks only. Any hint where I could start?
This little introduction is meant for whoever has a minimal knowledge on Objective-C and knows what he is doing.
NOTE: I will refer to the theos install path as $THEOS. This could be ~/theos, /var/theos, /usr/theos... Yeah.
The most popular way of creating MobileSubstrate extensions, also known as tweaks, is using Dustin Howett's theos build suite. Details follow:
What is theos?
So, we should start with what theos is not:
The Operating System
A Greek God
A compiler
And of course, what theos doesn't do:
Teaches you how to code.
Creates tweaks without having you to think
Sets up a whole building environment and/or installs the iOS SDK.
Theos is a cross-platform suite of development tools for managing, developing, and deploying iOS software without the use of Xcode, featuring:
A robust build system driven by GNU Make, which makes its Makefiles easily deployable through everywhere with theos installed too.
NIC, a project templating system which creates ready-to-build empty projects for varying purposes.
Logos, a built-in preprocessor-based library of directives designed to make MobileSubstrate extension development easy and with optimal code generation.
Automated packaging: Theos is capable of directly creating DEB packages for distribution in Cydia, the most popular mean of package distribution in the jailbreak scene.
How to install theos?
On OSX: Have the iOS SDK installed and follow these instructions.
On iOS: Install the BigBoss Recommended Tools package from Cydia and run installtheos3.
On Linux: Find a mean to have the toolchain installed, and follow these instructions.
On Windows: Nothing is impossible, but if you actually manage to do so, please let me know. :P
How to use theos?
This is a very asked question and too vague. Since theos is a whole suite of development tools, it doesn't make sense to ask How to use it, but more specifically, to ask How to create software using theos.
First of all, always have the Theos Makefile Reference in hand. It covers the basics of creating a theos Makefile, and that includes solving your linking issues adding a framework or private framework to the project.
Now, you can either create your own Makefile from scratch, create your little theos clone/symlink and start coding, but theos makes this step easier. You can just use nic.pl.
A very simple example of running NIC to create something can be found here. It's very straight-forward and sets you up right-away for programming.
Now, here's where we start getting back to topic.
Creating a tweak with theos
First of all, do not run NIC when inside $THEOS/bin. NIC will create the project directory exactly where you're running it from, and it avoids any project being created in $THEOS/bin. Therefore, you'll end up with a simple error which can be avoided by creating the project directory somewhere decent.
Run $THEOS/bin/nic.pl and choose the iphone/tweak template. You will be prompted by simple information which you may well know well how to answer, except for the last field: MobileSubstrate bundle filter.
Since a big part of MobileSubstrate is not just the hooker (the library which switches original methods/functions with yours), but also the loader (the part which gets your hooking to be inserted into certain processes), you have to supply this basic information for the Loader to know where to load your tweak. This field is but the bundle identifier for the application where this project will be inserted.
com.apple.springboard, the default option is the bundle identifier for SpringBoard, the application which is:
The iOS Homescreen
The launcher/displayer of common applications
The iOS Status Bar
Handler of some high-level essential background processes
Therefore, there's where many tweaks take place, altering behavior from something as trivial as app launching to something like how the whole homescreen UI looks like.
Programming a tweak with Logos
Now, the directory generated by NIC will contain:
The Theos Makefile, where you'll change information related to compiling
The control file, where you'll change packaging-related information
A symbolic link (or shortcut) to $THEOS named theos/
The main code file, defaulted as Tweak.xm. It is already added to the Makefile for compiling, so you can start coding right-away with it!
On knowing what to do
Now, you don't have SpringBoard's source code laying around, and you can't guess what methods to hook from nowhere. Therefore, you need a SpringBoard header set. For that, you need to use a tool named class-dump-z and run it into the SpringBoard binary (which is inside the iOS filesystem) to obtain header files including all class declarations and its methods inside the application.
From that (a deal of guessing and logging a method call is involved) you can start messing around with what you want in a tweak.
Of course, if you are not hooking SpringBoard you can use class-dump-z as you would in other binaries, such as UIKit, MobileSafari, etc.
Note that for when reversing App Store apps, they'll be encrypted. You'll need to decrypt those (I am unfortunately not allowed to tell you how-to), and then just run class-dump-z on them.
On obtaining private headers
Stuff like preference bundles require the headers for private frameworks, in that case the Preferences framework's headers. Else you'll get endless missing declaration errors (as I guess you could assume).
Getting them has the same logic applied the previous step. Run class-dump-z on, at this case, the Preferences binary and throw the headers at your INCLUDEPATH. The INCLUDEPATH is where the compiler will go looking for headers you include like #include <stdio.h>. Yes, stdio.h is inside one of the directories which build a compiler's INCLUDEPATH!
When compiling with a theos Makefile, $THEOS/include counts as part of your INCLUDEPATH, which means, you can just throw your dumped headers over there and include them later.
(Note that class-dumped headers aren't always perfect, so you're likely to have a couple of header-related compilation errors which can be easily fixed with something like removing a #import directive or changing it, or adding a couple of declarations.)
Code tips
You can't link against SpringBoard, so whenever you require a class from SpringBoard you have to use either the Logos %c directive or the objc_getClass function, as defined at <objc/runtime.h> to get it. Example: [%c(SBUIController) sharedInstance], [objc_getClass("SBUIController") sharedInstance].
When not knowing what a method does or how something works in SpringBoard, try disassembling it with IDA or others. I use IDA Demo (<- noob!) for my disassembling.
Looking at example code is amazingly helpful for both learning and figuring out how something works inside SpringBoard or others (again..). Great people at GitHub to have a projects looked at are rpetrich, chpwn, DHowett, EvilPenguin, and of course way more.
To also find about how SpringBoard and other works (...), have a look at a class's article at the iPhone Dev Wiki!
Epilogue
Wait, where's the good part? Where do I learn about coding in Tweak.xm?
Well, the original question was actually How to start MobileSubstrate tweaks programming?. You're all setup, hopefully with all headers placed, ready to type in make and see your project magically compiled with theos.
All you need to do is now to actually dig into your headers or your disassembly and go hooking, calling, etc.!
Logos Reference contains exactly how to hook and use other features of Logos, and the MobileSubstrate article on the devwiki is also a great read.
In case there is any doubt, don't hesitate joining the irc.saurik.com #theos IRC channel. It's a great way to discuss theos-related topics and ask questions. I'm mostly there, along with other greatly smart people ;)
You are looking for Theos created by DHowett.. Theos allows you to make tweaks, but it doesn't give you everything you need. You don't get every header for iOS, so you have to class-dump-z the frameworks/private-frameworks from the iOS SDK. Get started here: http://iphonedevwiki.net/index.php/Theos/Getting_Started, or join irc.saurik.net #theos for more help. You can also look at my projects that use theos: https://github.com/evilpenguin
You sound like you're looking for theos. Take a look at this, it should help get you started.
Does anyone know of an existing solution to help write tests for a NSIS script?
The motivation is the benefit of knowing whether modifying an existing installation script breaks it or has undesired side effects.
Unfortunately, I think the answer to your question depends at least partially on what you need to verify.
If all you are worried about is that the installation copies the right file(s) to the right places, sets the correct registry information etc., then almost any unit testing tool would probably meet your needs. I'd probably use something like RSpec2, or Cucumber, but that's because I am somewhat familiar with Ruby and like the fact that it would be an xcopy deployment if the scripts needed to be run on another machine. I also like the idea of using a BDD-based solution because the use of a domain-specific language that is very close to readable text would mean that others could more easily understand, and if necessary modify, the test specification when necessary.
If, however you are concerned about the user experience (what progress messages are shown, etc.) then I'm not sure that the tests you would need could be as easily expressed... or at least not without a certain level of pain.
Good Luck! Don't forget to let other people here know when/if you find a solution you like.
Check out Pavonis.
With Pavonis you can compile your NSIS script and get the output of any errors and warnings.
Another solution would be AutoIT.
You can compile your install using Jenkins and the NSIS command line compiler, set up an AutoIT test script and have Jenkins run the test.
About 2 months ago I overtook building proccess in current company. Even though I don't have much knowledge of it, I was the only with enough time, so I didn't have much choice.
Situation is not that good, and I would like to do following:
Labeling files in SourceSafe with version (example ProjectName PV 1.2)
GetFiles from SourceSafe to specific directory
Build vb6/c++/c# projects(yes, there are all kinds of them)
Build InstallShield setups
This is for now partly done using batch scripts(one for labeling and getting, one for building, etc..). So when building start I pretty much have babysit it.
Good part of this code could be reused.
Any recommendations on how to do it better? One big problem is whole bunch of dependencies between projects. Also labeling has to increment version and if necessary change PV to EV.
I would like to minimize user interaction as much as possible. One click on one build script(Spolsky is god) and all is done, no need to increment version, to set where to get files and similar stuff.
Is the batch scripting best way to go? Should I do some functionality with msbuild. Are there any other options?
Specific code is not need, for now I just need a way how to improve it, even though it wouldn't hurt.
Tnx,
Marko
Since you already have a build system (even though some of it currently "manual"), whatever you do, don't start over from scratch.
(1) Make sure you have a test machine (or Virtual Machine) on which to work. Thus you can make changes and improvements without having to worry about breaking anything.
(2) Put all of your build scripts and tools in version control, not just the source code. Then as you make changes, see if they work. If they do, then save them to version control. If they don't, then roll them back.
(3) Choose one area to work on at a time. Don't try to do everything at once. Going from a lot of manual work to "one-click" will take time no matter what build system you're working with.
Sounds like you want a continuous integration solution, like CC.Net. It has configuration options to do all the things you want and a great community to answer questions.
Also, batch scripting is probably not a good option. Sophisticated build and integration tools will let you feed parameters into the build and create different builds for different environments (test, production, etc.). Batch scripting will involve a lot of hand-coding and glue.
