@kolkov does this appear appear correctly when running delve CLI without IDEA? If so then it may worth checking out the API and see if there's a difference there and if we can do anything about that. If not then it's a thing from delve and if cannot be controlled via the API then we can't do anything about it.

@dlsniper I do not know how to try it from the console ((

[dlsniper]

run these:

C:/Go\bin\go.exe build -o C:\Users\Andy\AppData\Local\Temp\Run2go -gcflags "-N -l" inframe
C:\Users\****\.IntelliJIdea2016.2\config\plugins\Go\lib\dlv\windows\dlv.exe exec C:\Users\Andy\AppData\Local\Temp\Run2go

b filename:linenumber
c // to start debugging
// do what needs to be done
p variablename // or use help to see the list of commands, I haven't used the CLI in a while

Delve only reads the first 64 characters of string, from the command line you can read the next 64 by using this syntax: print variable[64:]. An API client can change the maximum length of a string by passing the appropriate parameter.

[dlsniper]

@kolkov I'm getting all the comments in this thread, thanks for ping.
@aarzilli please feel free to close the issue here and @kolkov please open the issue in the plugin tracker with a reference to this one.

Thank you.

[kolkov]

Thanks!

In case anyone is still looking here, I used config max-string-len 1000 in the delve terminal, and then p would print more of the string.

@chaimleib life saver! I wanted to add this is a config option you can persist ~/.dlv/config.yaml. In case, other's stumble upon this issue as I did.
