I want to write a simple plugin for oh-my-zsh completing only possible server arguments.
Example 1:
$ myserver st # hits tab
start stop
Example 2:
$ myserver # hits tab
start stop restart
According to wiki I have created file named ~/.oh-my-zsh/custom/plugins/myserver/myserver.plugin.zsh with sample content of coffee plugin (I tried brew plugin as well) but completition doesn't work (any of described in file). Moreover error is thrown:
_arguments:comparguments:312: can only be called from completion function
I checked similar problems and my fpath includes ~/.oh-my-zsh/custom/plugins/myserver.
What am I missing? This should be pretty simple... Thanks for help
From your post I'd assume that you have named the file myserver.plugin.zsh, however, if it is used to define a completion function its name must start with an underscore. It seems to be customary that the underscore is followed by the command name, i.e. in your case _myserver.
However, without the explicit code you are using I can not help you any further. You might want to check this blog post for further help.
I should remark that it is completely unnecessary to design a completion function as oh-my-zsh plugin; just create it as standalone piece of code.

I'm new to using coq/coqIDE and I'm not computer savvy either so I don't know whats wrong or what to call the issue. I was trying to go through the Software Foundations book, but coqIDE isn't working right. I'm using the latest windows 10, and coqIDE 8.10.2
The first issue is when I go to the tab compile -> compile buffer in Basics.v, coqIDE doesn't create a .vo file or a .glob. None of the other buttons worked either. Running coqIDE as admin didn't make it work either, but I figured out I can get around this by manually dragging Basics.v into the coqc application file.
I had no issues with coq working during the first lesson, but in the next lesson we're meant to import the definitions from Basics.v into Induction.v, when I run what they say
From LF Require Export Basics.
I get the error The file C:\Users\...\Coq Files\Tutorial\lf\Basics.vo contains library Basics and not library LF.Basics even though the _CoqProject file contains "-Q . LF" as it should.
I can get around this error too by just writing "Require Export Basics."
which properly loads, up until I actually try calling a definition from Basics
Running
Require Export Basics.
Example example: evenb 2 = true.
works until I get to evenb, and then gives the error
The reference evenb was not found in the current environment. even though it's in Basics.v
If I get even more anal and try
Add LoadPath "C:\Users\...\Coq Files\Tutorial\lf".
From LF Require Export Basics.
I get the error
Cannot find a physical path bound to logical path matching suffix <> and prefix LF.
And then finally if I try
Add LoadPath "C:\Users\...\Coq Files\Tutorial\lf".
Require Export Basics.
Example example: evenb 2 = true.
Loads properly.
So I'm wondering how should I fix the load path so that the project works without putting that junk in every file and how do I make the compile tab work.
There were some people talking about "hitting make in the top-level" but I have no idea what that means. I tried it anyway and ran the Makefile as a .bat even though I already downloaded it properly so there shouldn't be any need, but the Makefile didn't change anything anyway.
I don't think I'm forgetting anything, thanks in advance.
Instead of choosing Compile > Compile buffer, try Compile > Make instead (when browsing any one of the vernacular files in Logical Foundations) - I think that is what others meant by "hitting make in the top-level". But first, you may want to remove the workarounds you added in e.g. Induction.v, and save a trivial change in Basics.v such as adding/removing a newline somewhere in order to convince make to recompile it.
I am new to Coverity,I am using it from the command prompt with it's .exe files.So I want to pass specific macros in coverity cov-build.exe so that those macros will be implemented when cov-emit.exe(when it is called by cov-build.exe) is parsing the .c files.Till now I have tried the below stated configurations.
code-build.exe Intermediate_folder --delete-stale-tus --preprocessor-first --return-emit-failure "My_bat_file" -- -D My_macro_name=my_macro_body
So any help will be much be appreciated.I am stuck on this.
Thanks and regards,

cov-build wraps your existing build command, monitors it and spawns parallel compiler invocations in order to understand your code. These parallel compiler invocations will see the same command line being passed to your own compiler.
So if you want this define to take effect for your compiler as well as Coverity's then you should simply just add it to your build the way you would normally and Coverity will see it.
If you want to add a define that only Coverity's compiler can see, this is best done with within the config for your compiler.
You can either edit the config directly (add
<append_arg>-Dmy_macro_name=my_macro_body</append_arg>
after the <begin_command_line_config> line), or re-configure using --xml-option.
For example, if you're using the shortcut gcc config this would look like this:
$ cov-configure --gcc --xml-option=append_arg>-Dmy_macro_name=my_macro_body.
I noticed you're using --preprocess-first on the cov-build command line - I recommend against this, as it destroys XREFs making it much more difficult to browse defect information, as well as makes the analysis unable to find some defects (i.e. ones that are due to macros). --preprocess-next behaves like --preprocess-first and will only fire if the initial compilation attempt fails, so if you're using --preprocess-first to work around compilation issues, I strongly recommend using --preprocess-next instead.
If you do have compilation issues, it's always good to report them (along with a reproducer) to Coverity support so that they can be fixed in future releases.
I have a problem. I want to execute some commands in the Commandline of linux. I tested TProcess (So i am using Lazarus) but now when i am starting the programm, there is nothing, wich the Program do.
Here is my Code:
uses [...], unix, process;
[...]
var LE_Path: TLabeledEdit;
[...]
Pro1:=TProcess.Create(nil);
Pro1.CommandLine:=(('sudo open'+LE_Path.Text));
Pro1.Options := Pro1.Options; //Here i used Options before
Pro1.Execute;
With this Program, i want to open Files with sudo (The Programm is running on the User Interface)
->Sorry for my Bad English; Sorry for fails in the Question: I am using StackOverflow the first time.
I guess the solution was a missing space char?
Change
Pro1.CommandLine:=(('sudo open'+LE_Path.Text));
to
Pro1.CommandLine:=(('sudo open '+LE_Path.Text));
# ----------------------------^--- added this space char.
But if you're a beginner programmer, my other comments are still worth considering:
trying to use sudo in your first bit of code may be adding a whole extra set of problems. SO... Get something easier to work first, maybe
/bin/ls -l /path/to/some/dir/that/has/only/a/few/files.
find out how to print a statement that will be executed. This is the most basic form of debugging and any language should support that.
Your english communicated your problem well enough, and by including sample code and reasonable (not perfect) problem description "we" were able to help you. In general, a good question contains the fewest number of steps to re-create the problem. OR, if you're trying to manipulate data,
a. small sample input,
b. sample output from that same input
c. your "best" code you have tried
d. your current output
e. your thoughts about why it is not working
AND comments to indicate generally other things you have tried.
I frequently use the Scala console to evaluate and test code before I actually write it down in my project. If I want to know the contents of a variable, I can just enter it and scala evaluates it. But is there also a way to show the code of methods I entered?
I know there's the UP-key to show single lines, but what I was searching for is to show the whole code at once.
There's a file in your home directory named .scala_history that contains all of your recent REPL history. I regularly copy and paste code from this file into project source files. It's not exactly the same as showing the code for individual methods in the REPL, but it might help you accomplish the same goals.
See the comments by Paul Phillips in this issue for a discussion of some related functionality in the REPL (grouping statements in the history):
At some point I implemented the logic for this, but the real obstacle
is jline. It has enough trouble figuring out where the cursor is under
the simplest conditions. Start throwing big multiline blocks into the
history and it breaks down in tears. Would love to see this and
SI-2547 addressed by the community.
...
I expect to fix this soon too, but it depends on how well the recent
jline work goes. I implemented it long ago, and display issues are the
impediment.
Both of these comments are over two years old, so I wouldn't hold your breath.
I dont know a command to load all the code from command line.
What you can do is to :load path/to/my/file.scala to load some complex code and re- :load it when you changed the code in the file.
I never work with the GUI and am always inside a terminal (also full screen, so no title bar) set with the -nodesktop -nodisplay option. I also have different servers that I connect to, to run matlab and each of those have different restrictions on hogging computational resources. Since it's hard to remember which server I'm in,especially if I have multiple sessions open, I was wondering if I could change the prompt to display the server name. Try as I might, I couldn't find a resource that explains how to go about it (I'm beginning to think Mathworks doesn't support it). I know, a workaround would be to simply write a function call to system('hostname') and put the function in the path, so that it's about as easy as typing pwd to find the directory. I'd like to know if there's something more elegant.
There is a submission on the MathWorks File Exchange that can do this for you: setPrompt by Yair Altman. Using it in R2010b, I noticed that I was getting the warning message:
Warning: Possible deprecated use of set on a Java callback.
> In setPrompt at 115
Which I was able to suppress using the warning function like so:
warning('off','MATLAB:hg:JavaSetHGProperty');
And here's how I changed the prompt to the host name using the system function:
>> [~,systemString] = system('hostname');
>> setPrompt([deblank(systemString) '>> ']);
P11-4504>>
The function deblank is used to remove trailing whitespace (in this case a newline) from the string.
NOTE: The above changes (suppressed warning and modified prompt) don't persist after you quit and restart MATLAB, so you could put the above code in your startup.m file to apply them automatically every time you start a new session.
