Just install opensuse 11.x kde into my Lennovo X60, kick out the ms window. The must function, input Chinese can't work. When start IBus, it shows following message. How to edit $HOME/.bashrc? Actually I don't know where is $HOME.
Thanks. Forgive my foolishness.
IBus 已經成功啟動！如果您無法使用 IBus，請將下列代碼加入到 $HOME/.bashrc 中，並重新登入桌面。
export GTK_IM_MODULE=ibus
export XMODIFIERS=#im=ibus
export QT_IM_MODULE=ibus
IBus startup successfully! If you can't use IBus, pls. add the following code to $HOME/.bashrc, then restart desktop.
export GTK_IM_MODULE=ibus
export XMODIFIERS=#im=ibus
export QT_IM_MODULE=ibus
$HOME is just an environment variable on your linux installation, you can easily do echo $HOME in a console to find out where it points to.
Should be the home directory of your current user.
Tough the question maybe would fit better to http://superuser.com , because it is not really a programming related thing.

I know that when creating a .desktop file, one can set the metadata::trusted as true and false, in order to be able to launch the icon as an executable.
What is intriguing me however is the fact that:
When right-clicking on the .desktop file and "Allow launching" apparently the only thing it does is to set the metadata::trusted to true. The icon, however, changes, as expected, instantly to the icon described in the .desktop file Icon=.
However when setting the metadata::trusted to either false or true via command-line the icon doesn't seem to change its behavior
$ gio set android-studio.desktop metadata::trusted false
Once I refresh the Desktop manually (Alt + F2 >> restart) the environment refreshes and the icon turns to be executable again, BUT the whole environment is restarted.
So, What does exactly "Allow/Disallow launching" does after setting the metadata::trusted? How does it refresh the metadata in the .desktop itself without refreshing the whole Desktop?
Your question is exactly the same as what I'm looking for.
On Ubuntu 18.04 (GNOME 3.28):
dbus-launch gio set file.desktop "metadata::trusted" yes
and (although this is not quite what you need)
killall nautilus-desktop && nautilus-desktop & disown
Ubuntu 20.04 (GNOME 3.36):
dbus-launch gio set file.desktop "metadata::trusted" true
but no nautilus-desktop...
dbus-send --type=method_call --print-reply --dest=org.gnome.Shell /org/gnome/Shell org.gnome.Shell.Eval string:'global.reexec_self()'
or something like systemd*...
Look at this code:
https://gitlab.gnome.org/GNOME/nautilus/commit/1630f5348
and here search "trusted":
https://download.gnome.org/core/3.36/3.36.2/sources/
nautilus-3.36.2/src/nautilus-file-operations.c
nautilus-3.36.2/src/nautilus-mime-actions.c
It may turns out to be simpler.
From desktop-file-utils.
man desktop-file-install
For example:
desktop-file-install --mode=0755 --dir=$HOME/Desktop /path/to/source/file.desktop
Quiet interesting, I've used combination of the two previous answers in order to "Allow Launching" .desktop file located at my desktop within Kali Linux 2022 with GNOME Shell:
desktop-file-install --mode=0755 --dir=$HOME/Desktop ~/Desktop/Telegram.desktop
dbus-launch gio set ~/Desktop/Telegram.desktop "metadata::trusted" true
Note the order of the execution of the commands is important!
Here is similar topic at Ask Ubuntu: .desktop files - Allow launching - set this via CLI.
Also for these who are interested in here is How to install the latest version Telegram for Desktop via CLI which was the reason to searching for the current topic.
I am using WebStorm 2017.1.3 on Fedora 25.
I have fish set up as my default shell and installed oh-my-fish so in
Terminal I see my git branch and other information by default. omf update runs as expected.
In the WebStorm terminal emulator I still get fish, but not omf:
user#host ~> omf
fish: omf: command not found...
I'm a noob fish and omf user, can anyone help?
Thanks.
I have fish set up as my default shell and installed oh-my-fish so in Terminal I see my git branch and other information by default.
Note that you don't need omf for this. Fish ships a number of prompts that include vcs information. You can pick one with fish_config or add the __fish_vcs_prompt function to your fish_prompt.
In the WebStorm terminal emulator I still get fish, but not omf:
user#host ~> omf
fish: omf: command not found...
The "omf" function is stored in a file named "omf.fish" in a directory in $fish_function_path. This means that directory isn't included there.
The way omf works in a reasonably current (> 2.3.0) fish is that it has a bootstrap file (~/.config/fish/conf.d/omf.fish) that then sources the rest. It seems this isn't run.
I'd suggest you compare the values of $fish_function_path, $OMF_PATH and possibly $XDG_DATA_HOME in webstorm and outside of it.
An answer was given here: IntelliJ's embedded terminal does not load fish functions. I.e, add some lines of code to the app for the time being (until Jetbrains makes a fix).
I fixed this by going to Settings | Terminal then turning off Shell integration.
This allowed me to run omf and also have the bobthefish theme work with powerline/nerd fonts (after updating the terminal font at Settings | Editor | Color Scheme | Font Console)
I was using phpStorm 2017.3.4 but I assume this will also work in any IntelliJ embedded terminal.
When i tried to run following python code:
setlocale(locale.LC_ALL,"")
print getlocale()
The result is that it works fine if i run the script from Terminal.
But in eclipse/pydev with the same python compiler(python 2.7),it always return (none,none), any idea?
As you have already guessed from our conversation in the comments, this behavior is related to the environment. If you run Eclipse from the Terminal, you will get the same results you get when running Python directly from the Terminal.
So, your program is actually working fine. Depending on what you want to do, you don't need to worry about anything.
However, if you want to reconfigure your environment (system-wide or for all programs launched from the GUI, for example), you can do that in the appropriate files, using this answer as a guide.
For example, you may want to set the variables LANG and LC_ALL in one of those files, mimicking the configuration that is shown when you run the command locale from the Terminal. Assuming you want en_US with UTF-8, that added lines would look like:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
I'd like to use the xdg-desktop-icon tool because it can be scripted and works cross desktop (at least on Linux with Gnome and KDE). At least it is supposed to do so according to freedesktop.org. 1
Made a minimal file: test.desktop
[Desktop Entry]
Encoding=UTF-8
Type=Application
Exec=test
Icon=test
Name=test
Used xdg-desktop-icon...
xdg-desktop-icon install --novendor test.desktop
Exit code is 0. (Success.) But... I do not see any new icons on my desktop. Also not after reboot. This failed on Ubuntu Precise 12.04 with KDE and on Debian Wheezy with KDE.
How to use the xdg-desktop-icon tool correctly?
The problem on KDE has something to do with the desktop settings. Folder view, Newspaper view and so on.
xdg-desktop-icon relies on xdg-user-dir to determine the user desktop directory. You can check either against that command and the settings of your file manager (or program handling the desktop).
Assuming by default it would be /home/user/Desktop, then you have to check the file name there. If the file is there, then xdg-desktop-icon is working as expected.
You have to consider that the icon (test in your case) has to be installed separately using xdg-icon-resource. That is, if you are not using a stock icon or custom icon already installed or you are not using an absolute path for the icon.
Do not forget that xdg-desktop-icon only copies the .desktop file in a specific directory. No more no less.
If I am working on ~/myapp directory, I would check by doing:
$ xdg-user-dir
/home/user/Desktop
$ ls `xdg-user-dir`/test.desktop
ls: cannot access /home/user/Desktop/test.desktop: No such file or directory
$ xdg-desktop-icon install --novendor test.desktop
$ ls `xdg-user-dir`/test.desktop
/home/user/Desktop/test.desktop
Eventually, you can run with any xdg- script with:
$ XDG_DEBUG_LEVEL=1 xdg-desktop-icon ...
Which will give you an extra line telling you where the desktop file was installed. At this point, if the icon has not been installed, it might appear an ugly default icon.
Using Eclipse and CDT to debug C++ code the variable windows is cumbersome and not very informative for types defined in the standard template library or in boost (e.g. shared_ptr).
Just an example how this may look like for an std::vector:
bar {…}
std::_Vector_base<TSample<MyTraits>, std::allocator<TSample<MyTraits> > >
_M_impl {…}
std::allocator<TSample<MyTraits> > {…}
_M_start 0x00007ffff7fb5010
_M_finish 0x00007ffff7fd4410
_M_end_of_storage 0x00007ffff7fd5010
Even if this information about the internals of those types may be useful, in almost any cases I would expect a clearer presentation here, i.e. a list of values for the std::vector. Are there any tools, plugins or other modifications around which can do this?
EDIT
The following solutions does not work for linux. I am using ubuntu 14.04, eclipse, g++, gdb.
I cant find a package gdb-python and linux does not use mingw
You need a version of GDB capable of using python to pretty print structures. I know at least on windows using mingw that this is not provided in the default install.
Pretty Printers are python modules which tell gdb how to display a given structure. You can write your own, but there are already printers for STL available for download.
To Get Pretty Printers working on Windows (instructions should be similiar for other OS's):
Prerequisites
Make sure you have you have Python 2.7 installed and in the system path.
http://www.python.org/download/
Make sure MinGW-get is installed
http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/
Make sure you have an SVN client are installed
Installation:
Open a command Shell and type:
mingw-get install gdb-python
When its finished cd to a local directory and install the printers by typing:
svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python
Open the .gdbinit (create it in a text editor if need be) and type the following replaceing "C:/directory" with the folder that you checked the printers into.
Python
import sys
sys.path.insert(0, 'C:/directory')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end
Eclipse Setup
Go To Windows > Preferences > C/C++ > Debug > GDB
Where it Says GDB Debugger put the path to the python enabled GDB it will most likely be in the mingw /bin folder with a name like gdb-python27.exe
Where it says GDB Command File put the path to the .gdb init file you made earlier.
That's it, debug like normal, the stl structures should be much easier to read.
Well, gdb don't natively support STL containers. You can't say this is incorrect, since it will expose the inner workings of the STL objects, but most of the time it is not what we want, right?
If you're using gdb 7.0 you can take advantage of the pretty printers. This website http://sourceware.org/gdb/wiki/STLSupport has a pretty simple tutorial on how to set them. I copied below the part that interests you:
Check-out the latest Python libstdc++ printers to a place on your
machine. In a local directory, do:
svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python
Add the following to your ~/.gdbinit. The path needs to match
where the python module above was
checked-out. So if checked out to:
/home/maude/gdb_printers/, the path
would be as written in the example:
python
import sys
sys.path.insert(0, '/home/maude/gdb_printers/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end
The path should be the only element
that needs to be adjusted in the
example above. Once loaded, STL
classes that the printers support
should printed in a more
human-readable format. To print the
classes in the old style, use the /r
(raw) switch in the print command
(i.e., print /r foo). This will print
the classes as if the Python
pretty-printers were not loaded.
Since you're using eclipse cdt, don't forget to point your debug configuration to your .gdbinit file. When creating a new Debug Configuration, go to the Debugger tab and put the path to the .gdbinit file in the "GDB command file" field.
I hope that helps!
In debug view in variables list expand vector:
"vector_name" -> std::_Vector_base<"datatype"> -> _M_impl
then right click on _M_start and select "Display as array...", type its length and then click OK. Now you can expand each item of your vector.
If you have gdb support for CDT (see, for example, GDB in Eclipse), you could try this: De-referencing STL containers
Long ago I also stumbled upon your same problem. It was a pain to check the STL containers. Then I found that link and added to my .gdbinit file some of those definitions. Life was easier after that.
NOTE: My gdb version is 7.1 and adding those definitions work fine. I don't know if in newer versions of gdb they are already included.
I would like to expand on the Windows 7 response because some key steps are left out:
This is for MinGW users with Eclipse CDT
0) If you don't have python GDB, open a shell/command and use MinGW-get.exe to 'install'
Python-enabled GDB e.g.
MinGw-get.exe install gdb-python
1a) Get Python 2.7.x from http://python.org/download/ and install
1b) Make sure PYTHONPATH and PYTHONHOME are set in your environment:
PYTHONPATH should be C:\Python27\Lib (or similar)
PYTHONHOME should be C:\Python27
1c) Add PYTHONHOME to your PATH
%PYTHONHOME%;...
2a) Open a text enter, enter the following statements. Notice the 3rd line is
pointing to where the python scripts are located. See notes below about this!
python
import sys
sys.path.insert(0, 'C:/MinGW/share/gcc-4.6.1/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end
2b) Save as '.gdbinit' NOTE: Windows explorer will not let you name a file that starts with
with a period from explorer. Most text edits (including Notepad) will let you. GDB init
files are like 'scripts' of GDB commands that GBD will execute upon loading.
2c) The '.gdbinit' file needs to be in the working directory of GDB (most likely this is
your projects root directory but your IDE can tell you.
3) Open your Eclipse (or other IDE) Preferences dialog. Go to the C++ Debugger sub-menu.
4) Configure Eclipse to use C:\MinGW\bin\gdb-python27.exe as the debugger and your .gdbinit as the config file.
5a) Re-create all your debug launch configurations (delete the old one and create a new one from scratch).
--OR--
5b) Edit each debug configuration and point it to the new gdb-python.exe AND point it to the.
If you run into issues:
--Don't forget to change the location to the python directory in the above python code!
This directory is created by MinGW, so don't go looking to download the pretty printers, MinGW
did it for you in step zero. Just goto your MinGW install director, the share folder,
the GCC folder (has version number) and you will find python folder. This location is what
should be in python script loaded by GDB.
--Also, the .gdbinit is a PITA, make sure its named correctly and in the working folder of GDB
which isn't necessarily where gdb-python.exe is located! Look at your GDB output when loading GDB to see if a) 'python-enabled' appears during load and that the statements in the .gdbinit are appearing.
--Finally, I had alot of issues with the system variables. If python gives you 'ImportError' then most likely you have not set PYTHONPATH or PYTHONHOME.
--The directory with 'gdb-python27' (e.g. C:\MinGW\bin') should also be on your path and if it is, it makes setting up eclipse a bit nicer because you don't need to put in absolute paths. But still, sometimes the .gbdinit needs an absoulte path. if it works you'll see output from gbd (console->gdb traces) like this on startup of debugger:
835,059 4^done
835,059 (gdb)
835,059 5-enable-pretty-printing
835,069 5^done
....
835,129 12^done
835,129 (gdb)
835,129 13source C:\MinGW\bin\.gdbinit
835,139 &"source C:\\MinGW\\bin\\.gdbinit\n"
835,142 13^done
835,142 (gdb)
I know that JDT (Java environment in eclipse) provides custom "formatters" to be applied when displaying variable values in debug views. A quick look at google for the same in CDT brings this page:
http://wiki.eclipse.org/CDT/Better_Debugging_%28GSoC_project%29
I don't know if this has been yet integrated in the main CDT line, may be you can try to right click on a variable while debugging (in the last CDT) and see if there is a custom formater entry. If not available I recomend you to add a new tracker entry in CDT tracker to ask this enhancement.
