non-nil error value when it fails to open a file. func Open(name string) (file *File, err error) The following code uses os.Open to open error definicion a file. If an error occurs it calls log.Fatal to print the error message and stop. f, err := os.Open("filename.ext") if err != nil { log.Fatal(err) } // do something with the open *File f You can get a https://www.powerthesaurus.org/open_to_error/synonyms lot done in Go knowing just this about the error type, but in this article we'll take a closer look at error and discuss some good practices for error handling in Go. The error type The error type is an interface type. An error variable represents any value that can describe itself as a string. Here is the interface's declaration: type error interface { Error() string } The error type, as with all built in types, is predeclared in https://blog.golang.org/error-handling-and-go the universe block. The most commonly-used error implementation is the errors package's unexported errorString type. // errorString is a trivial implementation of error. type errorString struct { s string } func (e *errorString) Error() string { return e.s } You can construct one of these values with the errors.New function. It takes a string that it converts to an errors.errorString and returns as an error value. // New returns an error that formats as the given text. func New(text string) error { return &errorString{text} } Here's how you might use errors.New: func Sqrt(f float64) (float64, error) { if f < 0 { return 0, errors.New("math: square root of negative number") } // implementation } A caller passing a negative argument to Sqrt receives a non-nil error value (whose concrete representation is an errors.errorString value). The caller can access the error string ("math: square root of...") by calling the `error`'s Error method, or by just printing it: f, err := Sqrt(-1) if err != nil { fmt.Println(err) } The fmt package formats an error value by calling its Error() string method. It is the error implementation's responsibility to summarize the context. The error returned by os.Open formats as "open /etc/passwd: permission denied," not just "permission denied." The error returned by our Sqrt is missing information about the invalid argument. To add that information, a useful function is the fmt package's Errorf. It formats a string acco

The below code prompts the user as to whether or not a specific file is open. If the user clicks no, the sub ends. If they click yes, the sub continues. I have tested this with the file open and all open to error works great. But then I forgot to open the file and clicked yes when prompted and received the following error: Run-time error '9': Subscript out of range For this line in the code: With Workbooks("Swivel - Master - December 2015.xlsm").Sheets("Swivel") I understand why I am getting the error, but how do I check if the "yes" answer from the user is true to prevent this error? Here is the full code: Sub Extract_Sort_1512_December() ' ' Dim ANS As String ANS = MsgBox("Is the December 2015 Swivel Master File checked out of SharePoint and currently open on this desktop?", vbYesNo + vbQuestion + vbDefaultButton1, "Master File Open") If ANS = vbNo Then MsgBox "This procedure will now terminate.", vbOKOnly + vbExclamation, "Terminate Procedure" Exit Sub End If Application.ScreenUpdating = False ' This line renames the worksheet to "Extract" ActiveSheet.Name = "Extract" ' This line autofits the columns C, D, O, and P Range("C:C,D:D,O:O,P:P").Columns.AutoFit ' This unhides any hidden rows Cells.EntireRow.Hidden = False Dim LR As Long For LR = Range("B" & Rows.Count).End(xlUp).Row To 2 Step -1 If Range("B" & LR).Value <> "12" Then Rows(LR).EntireRow.Delete End If Next LR With ActiveWorkbook.Worksheets("Extract").Sort With .Sor

When I click on View > Console I get the following error: Failed to open path '/home/username/.config/LightTable/ltcache/default.clj' with error: Error: ENOENT: no such file or directory, open '/home/username/.config/LightTable/ltcache/default.clj' Berkana commented Mar 1, 2016 I also got this problem. I'm using the most recent version of MacOS X. naomik commented Mar 8, 2016 👍 Same for me on OS X Light Table member kenny-evitt commented Mar 9, 2016 @henrywright @Berkana @naomik Where are you seeing the error? In the console? I can't reproduce this on my Mac [F]. rundis commented Mar 9, 2016 Hm not able to reproduce either. Even after deleting the ltcache directory. Does it help if you create the dir manually (and optionally an empty default.clj in the appropriate location) ? henrywright commented Mar 9, 2016 @kenny-evitt it looks as though it's showing inside the console. henrywright commented Mar 9, 2016 @rundis I thought let me try clicking View > Console again (before I try creating the dir manually as you suggested). Now I see something different. I no longer get the error message, just a blank console. I assume that's what I should be seeing? rundis commented Mar 9, 2016 @henrywright Unless there is something actually logged to the console, yeah ! 1. try opening a new tab (cmd/ctrl + n) 2. cmd/ctrl + enter 3. Editor: Set current editor syntax 4. Select say JavaScript 5. Enter something like console.log("hello") 6. Eval the line (cmd/ctrl + enter with the cursor placed at the end of the line) you should see hello
