Code Snippet Managers for Linux Desktops

Code Snippet Managers for Linux desktops?

Have you seen jCodeCollector? It's a significantly less complicated clone of CodeCollector, but is multiplatform (java). It is available from https://github.com/alessandrococco/jcodecollector

There is also Acire, a project started by Jono Bacon of Ubuntu fame, which is management library for useful python snippets. While full of useful tidbits, it is however, language and linux-specific.

Best way to manage code snippets in Linux?

I think this is what you are looking for: Snippely and jCodeCollector

I use Snippely on my mac, it awesome.

Update: Moved to Dash for mac: http://kapeli.com/dash

Process management code behaves different on Linux and Windows - Why?

The problem is your assumption about btsync. Let's start it:

./btsync

BitTorrent Sync forked to background. pid = 24325. default port = 8888

So, that's the whole story right there: BitTorrent Sync forked to background. Nothing more. Nothing less. If you want to, btsync --help tells you to pass --nodaemon.

Testing Process Termination

Let's pass --nodaemon run btsync using the test program. In a separate subshell, let's kill the child btsync process after 5 seconds:

sehe@desktop:/tmp$ (./test; echo exit code $?) & (sleep 5; killall btsync)& time wait
[1] 24553
[2] 24554

No problem!

A Better Fake Btsync

This should still be portable and be (much) better behaved when killed/terminated/interrupted:

#include <boost/asio/signal_set.hpp>
#include <boost/asio.hpp>
#include <iostream>

int main(int argc, char* argv[])
{
    boost::asio::io_service is;
    boost::asio::signal_set ss(is);
    boost::asio::deadline_timer timer(is, boost::posix_time::seconds(20));
    ss.add(SIGINT);
    ss.add(SIGTERM);

    auto stop = [&]{ 
        ss.cancel();    // one of these will be redundant
        timer.cancel();
    };

    ss.async_wait([=](boost::system::error_code ec, int sig){ 
            std::cout << "Signal received: " << sig << " (ec: '" << ec.message() << "')\n"; 
            stop();
        });
    timer.async_wait([&](boost::system::error_code ec){
            std::cout << "Timer: '" << ec.message() << "'\n";
            stop();
        });

    std::copy(argv, argv+argc, std::ostream_iterator<std::string>(std::cout, "\n"));
    is.run();

    return 0;
}

You can test whether it is well-behaved

(./btsync --nodaemon; echo exit code $?) & (sleep 5; killall btsync)& time wait

The same test can be run with "official" btsync and "fake" btsync. Output on my linux box:

sehe@desktop:/tmp$ (./btsync --nodaemon; echo exit code $?) & (sleep 5; killall btsync)& time wait
[1] 24654
[2] 24655
./btsync
--nodaemon
Signal received: 15 (ec: 'Success')
Timer: 'Operation canceled'
exit code 0
[1]-  Done                    ( ./btsync --nodaemon; echo exit code $? )
[2]+  Done                    ( sleep 5; killall btsync )

How to create desktop shortcut passing custom arguments?

You need to make the copied chromium.desktop file executable. With Dolphin file manager: right-click on your .desktop file → Properties → Permissions tab → check Is executable checkbox.

Alternatively, from the folder with your .desktop file, you can run:

chmod 755 chromium.desktop

Now it should be able to launch Chromium.

To add a custom argument(-s) to the launcher - back in the Properties of your .desktop file go to the Application tab and add your argument(-s) to the Command field after the path to the executable, for example:

/usr/bin/chromium --profile-directory="Default"

While we are at the Application tab, you may want to change the Name field to something like "Chromium w/args" to help distinguish launchers later on.

As an option, you can edit the .desktop file by opening it with a text editor of your preference. To edit the launch command, navigate to the [Desktop Entry] group header, under which locate the line starting with Exec= and add custom arguments to it.

To edit the name of the launcher, under the same header locate lines starting with Name= (Name[xx_XX]=, e.g. Name[en_US]= for localized names) and alter them as you wish.

More information on Desktop Entries can be found in its specification or on ArchWiki

To add your new launcher to the application menus (for the current user) - move .desktop file to the

~/.local/share/applications/

Now your launcher will be available in Application Launcher and Krunner.

If you want the new launcher to co-exist with the original (instead of overriding it), you should rename the .desktop file to something like chromium_args.desktop.

How do you manage your gists on GitHub?

Check out GistBox. It supports searching, editing and labels. Here's a screenshot:

There's also a demo video at: http://www.youtube.com/watch?v=VLgyY6lqpsQ

GistBox Clipper (a Chrome extension) also provides the ability to save <pre> tags and arbitrary text on any web page.

Edit:

Unfortunately, GistBox is becoming Cacher cacher.io - the free plan will only include: 15 private snippets, 3 private labels, unlimited public snippets. If you plan on having many private gists then you will need to but (sic) a paid plan. – Bartek Skwira

In KDE, how can I automatically tell which Desktop a Konsole terminal is in?

With dcop, the kde Desktop COmmunication Protocol, you could easily get current desktop executing

  dcop kwin KWinInterface currentDesktop

command. If you are working with new kde 4.x dcop is no more used, and you can translate the command to a DBUS call. It should be quite simple to send/get dbous messages with python apis.

Managing keyboard shortcut conflicts between IDE and OS (Ubuntu)

I use Ubuntu as well and I disabled the native (Ubuntu) command Ctrl + Alt + L because I prefer IntelliJ's format code than this native Ubuntu command. However, in the 2nd case I prefered Ubuntu's shortcut so I didn't change anything.

So basically, you can choose which option you need more and then act accordingly.

Of course, until IDEA becomes Ubuntu friendly.

In the end, Ubuntu will always prefer its shortcuts and so far I haven't found any tool that can disable native shortcuts on request.
