I need to create a firefox plugin that allows a user to take screenshots of any part of their desktop and have them uploaded to a server. There seems to be lots of plugins for screen capturing a webpage, but nothing for capturing anything outside of firefox. So after a little research I have not found much information on how this might be possible. I don't want to resort to a using a java applet but I will if that is my only option.
Does anyone have advice on how I might create such a feature?
Thanks
I don't think a Firefox addon is the most appropriate approach here. Maybe split the task into a Firefox addon to offer the "upload to a server" component and a native app to do the desktop screenshot (or just integrate with existing screenshot tools).
If you're worried about complicating the installation process for end users, you could look into bundling the addon component and native app into a single installer (e.g. MSI on Windows, RPM on Linux, etc.). You'll have to come up with different apps for each platform you want to support (and maybe even each version - e.g. Windows XP vs Windows 10).
Whatever you decide, you'll probably need to create a more specific question to get further help here (there's no simple Firefox.Addons.API.TakeScreenShot() answer I'm afraid).
Also make sure you're using the right terminology - a plugin is the deprecated NPAPI approach whereas addons are still supported.
I'm actually working on taking native desktop screenshots just in the last coupel of days. I'm using js-ctypes. My work goal is the same exact thing to, upload to server. If you would like to collaborate I am very open to it! We can chat about it on #jsctypes irc channel :) irc://moznet/jsctypes (Mibbit IRC WebApp) If you don't know js-ctypes thats ok i can handle that while you can handle uploading techniques, and an editor on canvas :) The editor is a huge part of it, you can see my ideas/plans here: https://github.com/Noitidart/NativeShot/wiki/NativeShot
I'm really really interested in a collab on this!
I'm still working on windows right now, the color is messed up: https://github.com/Noitidart/NativeShot/tree/digitanks-method
I was just about to start OSX work following this example here: https://developer.apple.com/library/mac/samplecode/SonOfGrab/Introduction/Intro.html and here: Take ScreenShot without Window
You can install the addon from that branch and click the icon that gets added to the toolbar, it will take a screenshot with 3sec delay and then append it to the body of the selected tab. (Windows only right now)
Doneskis baby check it out: https://addons.mozilla.org/en-US/firefox/addon/nativeshot/
Got some quirks. Released it as v1.0 though. I'm working on Android support, pretty close. I need to flesh out the editor tools. Please let me know if you're willing to collaborate.
I'm using Windows, Mac and Linux machines in my daily duties. On all machines, I program in C++ and various shells scripts. So far I've adopted the various "main" IDEs on each platform, but the diversity is irritating. I'm therefore looking into the possibility of using Sublilme Text on all platforms.
I have a setup of Sublime Text on Windows that works perfectly and would like to use the same on the other platforms also, so that when I change something in my Sublime setup on, say, my Mac, I can easily pick up the latest setup on my Windows machine the next time I'm there.
Is this possible on the 3 mentioned platforms, without getting (more) grey hair? If so, any suggestions or experiences thereof?
Many folks upload the "Packages/User" folder to GitHub (or your VCS service of choice). Then, they use Package Control to install their packages. Package control, through a settings file, will install any missing packages on a particular machine. I wrote a bit more about it here. You would then clone the git repo onto each machine, pulling updates when you decide to change something.
Alternatively, you could probably use a cloud service + symlinks to keep things auto synced, but I've personally never used it that way.
There are some plugins that are platform specific, so keep an eye out for those.
There's also the Package Package Syncing, which syncs installed packages and settings via some cloud service.
Works quite nicely, and automatically.
Has the advantage that you don't have to push/pull some dotfiles repo all the time.
No idea though whether this will work seamlessly across platforms (meaning whether all the settings will be platform-independent).
I have two PCs both with XE2. I thought that I had installed identically on both but have problems installing 3rd party packages on one while the other is just fine.
I want the same on both anyway. The easist would probably just to "migrate" the working set-up by moving in into my Dropbox folder. Can I do that? If so, how?
If not, can I (easilly) backup my registry settings on one machine and then import them on the other?
I suppose I could just sort out the problem on the one PC, but am not having much luck so far. I would rather invest the time in only having one Delphi setup. And since I am moving lots of other stuff to DropBox anyway ...
The tool for this is now built into Delphi XE8 and higher.
It's found here:
C:\Program Files (x86)\Embarcadero\Studio\20.0\bin\migrationtool.exe
Online documentation:
http://docwiki.embarcadero.com/RADStudio/Rio/en/Settings_Migration_Tool
Install CnPack wizards from http://www.cnpack.org
From the CnPack toolbar select IDE Config Backup/Restore (image below) and save this file somewhere safe
Copy the components to the second delphi machine . Keep the exact same directory structure.
I store my components as follows this helps backing up, moving etc., but you can use your own structure
D:\components_bds\DCU
D:\components_bds\BPL
D:\components_bds\ComponentsThemselves
Use the restore config file from CnPack to restore your components on the new machine
This is also useful if your testing components that you plan to remove later and keeping a backup of your installation incase something goes wrong you can save time with new delphi installation if hard drive dies. Keep a copy on flashdrive or somewhere safe
You may compare/diff the config file created by cnPack using a tool like Beyond Compare and see what the differences are to find out why third party components give problems on one of the machines. It may be a Delphi registry/installation problem or a problem in the paths of the thirdparty components. Components need to be installed in an order perhaps it did not find the needed dcu or dll it depends on.
I don't know of any way to do so with DropBox. Here's an old post I made (related to Delphi 7, but with correction of registry keys still applicable) in the CodeGear newsgroups; hopefully it will help.
(It probably goes without saying, but back up the existing registry settings on the destination machine before starting by using RegEdit and exporting them, just in case. You'll at least be able to get back to the point you're at now if something goes wrong by deleting the imported entries and then importing the saved ones.)
You can't, without some difficulty anyway. (Especially if you have
third party components installed, as they may have placed files in the
%SYSTEM% folder you may not know about.)
You may be able to (for going from the old computer to the new
computer running the same exact version of Windows!) by exporting the
registry keys under HKCU\Software\Embarcadero and
HKLM\Software\Embarcadero from the old machine, and then after
installing Delphi on the new machine (in the exact same folder
location) importing that registry file.
Many of the compiler, linker, and other settings are configured on a
per-project basis, and should transfer over when you move your source
code to the new machine.
Third-party components are a problem, as I mentioned above. You may be
able to get away with using the registry export/import if you copy
each third-party component set from the old computer into exactly
the same location on the new machine before importing the registry
file. You'll probably have to track down some .BPL files that end up
in the $(BDS)\Bin and possibly other folders under the $(BDS)
tree; the IDE will tell you about missing stuff when you try and start
it. Make sure you answer "Yes " when asked if you want to try and load
it again next time!
Most of my development is hobby stuff or wannabe releases. Instead of dying trying to move my XE2 Pro from my Dell Inspiron N7110 Win 7 machine to my new Win 10 SSD machine, I'm seriously thinking of switching to Lazarus. I've used Lazarus 2.x with Indy 10, ZeosLib, and Firebird and successfully created a working distributed internet system. I also created Lazarus version of my XE2 Blackjack program. When compared to XE2, Lazarus (IMO) has only two weakness and neither are deal breakers for me. BTW, I have successfully duplicated Lazarus (with all installed components) from one machine to another simply by copying and pasting the Lazarus directory and it works. Try that with Delphi.
Sam
I'm a novice iOS developer with a basic knowledge of Xcode. I have one app in the app store that I made myself with Titanium. For a next project I've enlisted the help of two more experienced programmers in another city. I have a question in two parts about the collaboration between us:
I want to propose a work routine that gives me access to the project as they are working on it, so that I can device test builds during the development process - without interfering with the coding. What is the best way to do this? Is sharing the project or codebase via Dropbox an option? Does anybody have any experience with this?
Are there any pitfalls I should be aware of when pursuing this kind of work routine?
Thanks!
Use a source control system like Subversion, Git, Mercurial.
XCode has built in support for Subversion/Git.
Use source control. Github is a great place to start. (private repositories will cost money though.)
I used to use DropBox to share code between my two machines, but DropBox would routinely ruin work if I wasnt careful. DropBox is NOT version control. If you do insist in using Dropbox, don't open your code on more than one machine at once. Nuff said.
Searching with '[Delphi] "source control"' didn't return much, so here goes: For those of you Delphi programmers working on your own, what source control do you like? I know about TortoiseSVN (which can be used without a server), but I'd like to know if there are better options before choosing it.
Thank you.
SVN will be more than enough as you'll mostly use it for backing up and diff'ing versions.
You can use VisualSVN Server and TortoiseSVN with Delphi IDE Integration. All of these are freeware. If you wish to use any other freeware SCM with Delphi IDE integration you'll need to buy SourceConneXion or Athlant. Also, if you're using D2009 you'll need to convert strings to ansistrings in order to get TortoiseSVN addon for delphi to work.
I use Mercurial, and have used Bazaar and Perforce (free for small teams). All are good, but nowadays I tend to prefer Mercurial. Mercurial comes with its own tortoise
which, while not quite as polished as TortoiseSVN, is perfectly usable:
(source: sourceforge.net)
For users of RAD Studio XE or XE2, Uwe Schuster has published an IDE add-on called Version Insight Plus that adds Mercurial and Git support to the IDE's built in version control support.
For all the systems I have mentioned, no central server is required.
I would recommend Git which is free & open source and:
Doesn't require you to even set a central server even if you want add more developers or machines.
Is Extremely Fast (imo)
Encourages the use of branches
I use it for almost every new project, even when it's just me on the project. It's an extremely fast distributed version control system and was written by Linus Torvalds and is now used in high profile projects like the Linux Kernel and Ruby on Rails.
Git isn't hard to use from the Command line but also has it's own "Tortoise" package (TortoiseGit - albeit not as polished as it's SVN cousin).
SourceGear Vault is free for a single user. I like to use the external client because I work in different environments, but If you want Delphi IDE integration, you can use Source ConneXion (not free).
You might look at some of the responses here (Stack Overflow) if you do have Delphi in mind. As mentioned in the answers there, I use Team Coherence which integrates very nicely with Delphi's IDE, and is aware of Delphi file groups (.pas with .dfm etc). I think it's written in Delphi too.
Having said that, the other comments already made are true - you shouldn't really let your choice of language dictate your choice of VCS.
Even though you've said single user, I would look for a solution that allows you to easily host it on a server/other desktop machine, so you have separated your development machine from your source repository. I'm probably teaching granny to suck eggs but you ought to check that whatever you choose can be easily backed-up too (even to a USB key or external drive would be fine). :-)
I know you have asked for Source Control, but if you are always planning to be a 'single developer' you might like to consider an automatic backup solution like AJC Active Backup instead. Yes, you lose the ability to check in and out specific versions, but at the same time you avoid the need to check stuff in and out all the time when it is only you working on a project. And you can recover or diff any previous source files by date for as far back as you care to configure. It's very much a set-and-forget solution, until you need to recover something, when it is invaluable. And the archive itself can be backed up in the normal way.
I use TortoiseSVN, but store my repositories as files on my laptop (on a share that can be accessed by mutilple VMs), not managed by a server. This means that I have full access to the repository regardless of server access, but also allows me to easily backup the repositories to the company file server when connected.
Since I am the only programmer I have not needed a separate server so far. I have seen Nick Hodges (Delphi Development Manager) say very nice things about VisualSVN Server, and I aim to check this out, to see how easy it is to backup/restore the repository: if that can be automated, and done very quickly, then I will probably adopt that.
Longer term I am going to look at the various flavours of distributed VCS, as that may be better suited to multiple laptop-based developers; I'm not sure yet, as I've not reached that page of my to-do list ;-)
One of the things supposedly in the pipeline for Delphi is integrated support for VCS. I've no details on that, or on any implications for current users of the various traditional or distributed VCS.
The language you use doesn't really matter in the choice of the SCM you will use.
It can matter if your favorite IDE supports or not this SCM.
TortoiseSVN is just a svn client, if you choose svn you can have several client.
I use Tortoise, and subclipse for committing in the same svn repository.
I would suggest using SVN server on a separate machine (either VisualSVN as suggested before or CollabNET Subversion Server) and TortoiseSVN with JVCL integration expert (also as suggested before).
Besides getting all the good stuff from the version control, you'll also automatically have backup on a different computer, which is always a good thing.
I know this will get down voted, but I feel it has to be said.
I've used Version Control software for many years at my job, and it is required when multiple people work together - to make absolutely sure that no two people overwrite one-another's work.
But for my personal development at home I don't use one. I find them overbearing and inconvenient for a simple one-person project. And I've tried several packages including Source Gear Vault and some others that other people have mentioned.
What I do instead is at every significant change to my program that I might want to go back to, I make a copy of the entire program directory. If I screw up in the next change, I can go back to the copied directory.
I also permanently keep copies of all my directories of every release of my program. If I ever need to do comparisons between my current version and previous releases, or between two different previous releases, I use Beyond Compare by Scooter Software - a simply great tool for diff-ing and copying changes between versions. If you use Source Control software, Beyond Compare will integrate into it nicely.
So I mention this simply because I have often heard everyone pushing Version Control Software, even for the individual developer. For some of us, it's overkill.
You may want to consider this simpler solution.
I use Bazaar with Delphi and it works well, especially for solo developer workflows. It has it's own TortoiseBzr but it isn't as good as some of its cousins so I recommnend the excellent Bazaar Explorer instead. One of the great things about Bazaar is it's flexibility and the ease with which you can change workflow or include another developer in a project that started off solo.
A lot of articles about Bazaar will tell you it is a lot slower than Git or Mercurial. They are out of date, now it takes a similar time to acomplish operations as they do and is faster on some operations.
My team use StarTeam and I have never used something else like SVN so it is hard for me to do a good compare. Starteam has both positive and negative sides.
Pros:
You can register Change requests and
connect them to checkins. This make
changes more trackable.
I feel more comfortable with a real GUI compared to commandline or some Shell
extension.
Cons:
Expensive, as most products from
Borland...
Latest version use Java. It is almost like the previous Win32 version and they have added more features, but I still feel that it is some slower and more memory hungry than before.
GUI could be a bit more intuitive.
I'm not big on version control, but use SVN/Tortoise and am quite happy with it. The main benefits that I see for a single developer is being able check out older versions of the application, and use multiple computers for development (desktop / laptop) - other than the obvious backup benefit. I tend to not need it for diffing files, as I find the version control tools within the Delphi IDE fairly good for this - provided the "bug" was introduced recently.
I think most Delphi developers use SVN/Tortoise (making it a fairly safe choice) - but there are trendyer options such as Mercurial and Git.
As a single developer, I have used Perforce for a number of years. It has been great. Aside from a CLI, you can use the P4V client. There's also an explorer plugin available, as well as Delphi IDE integration. I actually just found this free integration on Torry yesterday:
p4delphi
I've installed it in Delphi 2010, and it works pretty good.
Perforce is free for two user, it would require you to install perforce server, but the server footprint is very, very small. you can use P4V (Perforce visual client) which is far more convenient than tortoise, it also provide Windows explorer extension to be have just as tortoise (but you could skip this installation). Delphi integration could be done using P4Delphi.
I am using subversion, bug tracking and simple to use project planning for my latest delphi project from an web service provider. http://www.unfuddle.com has a free account for projects less than 200mb with 1-2 developers and the user interface is easy to use.
