I was wondering if there is any way in Intellij to know the output of the next line while debugging?
Sometimes errors occur in the next line for which I have to use expression elevator to see what kind of error, error message etc.
Watching(or evaluating) every next line and showing the result before hand without breaking the flow would be helpful.
Any setting, any plugin?
Did you try to use Evaluate expression? In case ob exception you will see it but debug mod won't be stoped

I'm using geom_bar_pattern to try to put stripes in an stacked barplot. I could run the command once, but I'm trying to do it again and it doesn't work. The error is Error in seq.default(from, to, by) : invalid '(to - from)/by'
I received the same error and realized that this was due to the limited size of my screen. I was able to see the figure and resolve the error by expanding the built-in plot viewer...
I just got the same error message with geom_bar_pattern. In my case it was entirely a matter of spacing in the plot: I had a long string of text for one axis ticks. When I reduced that, I immediately got rid of the issue!
Not sure if it's the same situation in your case, but I thought I'd answer just in case this could help...
Good luck!
Getting warning from Script Checker : "OMEGA13 was used but was never set (will evaluate as its name)"
I've set
start using Omega13
-- some codes here --
stop using Omega13
Anyone has any idea on why the warning sign is there?
Eggplant documentation - Advance scripting: Error Recovery with Omega13
What's probably happened is somewhere you've mistyped some variant of omega13.
Sensetalk treats uninitialized variables as strings. This results in lots of hard to debug errors.
name = "my name"
put naame
This will print naame which is probably not what you wanted.
It looks like the correct form to invoke is omega13 not Omega13, or OMEGA13. I'd check the documentation and make sure that you haven't mistyped it anywhere.
You may also want to look into the strictVariables global which if true will treat using an uninitialized variable as an error.
i am writing a compiler for a small language using byacc/j and jflex. i have no problem in finding first error in a given input file. the problem is i cant find more errors. first i used to use yacc and lex and i used special symbol 'error' token at the end of some grammar rules which was built in yacc and i could use 'yyerrok' to simply continue parsing and finding more errors but , in byacc/j i cant find something like that and yyerrok does not work and byacc/j does not recognize that. any suggestions to find more than one error in byacc/j ? or is there ' error ' and 'yyerrok' in byacc/j ?
The only thing that yyerrok does is reset the count of tokens since the last error notification. Yacc parsers suppress error messages in the first three tokens after an error recovery, to prevent cascading error messages.
Using yyerrok -- or setting yyerrflag to 0 -- indicates that error recovery was successful and that error messages should now be produced. It does not have any other effect: with or without yyerrok, parsing will continue.
yyerrok is a C macro, and Java doesn't have macros. So apparently it was dropped from the Java interface. But yyerrflag exists as a parser class member and you should be able to just set it to zero in a parser action.
I want log something when breakpoint is hit in AppCode. But there is no documentation for how to write a right evaluation expression for the evaluate and log section on debug configuration window.
if i write
NSlog(#"some message")//error
the console log:
error evaluating NSLog(#"some message");: Cannot find the execution point
I have no idea how to write correctly!
There is a feature in AppCode called "Evaluate expression" (⌥F8). You can call it during the Debug and evaluate particular code expression without p/po and LLDB console. You can normally write the code in the window, press "Enter" and see the result of this particular expression.
This field uses this feature to evaluate some particular code at breakpoint, and evaluation result of NSLog is void. Here you can right for example something like self.view.frame.size.width <= 100 and have result printed to console. If you want just print some message to console - select only Log message to console and AppCode will print something like
Breakpoint reached: ViewController.m:6
What im trying to do is write a key to the registry but im stepping from one problem to another, first permissions problem, now this..
This is the line of code.
If PNGchk.Checked = True Then
My.Computer.Registry.Users.CreateSubKey(UserSID & "\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.png\UserChoice", True, Security.AccessControl.RegistryRights.FullControl).SetValue("Progid", "SIV.png", Microsoft.Win32.RegistryValueKind.String)
End If
You must have Option Strict Off for that code to even compile, so you might want to fix that to start with. Option Strict On would have flagged issues with that code right away. You should read the documentation or at least pay attention to Intellisense for that method because your second and third arguments make no sense. No overload that I can see has a Boolean parameter and if you want to use a RegistryRights value you do so within a RegistrySecurity object as far as I can see.
RegistryKeyPermissionCheck.ReadWriteSubTree worked for me.
Using clsid64 = view64.CreateSubKey("Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.png\UserChoice", RegistryKeyPermissionCheck.ReadWriteSubTree)
clsid64.SetValue("StubPath", "SIV.png")
clsid64.Close()
End Using
