# Configure Max String Print Length For Delve
|
|
|
|
During a [Delve](https://github.com/go-delve/delve) debugging session, we can
|
|
print out the value of a given variable with the `print` command. Similarly, we
|
|
can see the values of all local variables with the `locals` command.
|
|
|
|
Whenever Delve is printing out strings and slices, it will truncate what it
|
|
displays to 64 characters (or items) by default.
|
|
|
|
```go
|
|
(dlv) print diagnostics.Solutions[0]
|
|
"295743861\n431865972\n876192543\n387459216\n612387495\n549216738\n7635...+25 more"
|
|
```
|
|
|
|
This can be overridden by [changing the `config` of
|
|
`max-string-len`](https://github.com/derekparker/delve/blob/237c5026f40e38d2dd6f62a7362de7b25b00c1c7/Documentation/cli/expr.md?plain=1#L59)
|
|
to something longer. In my case here, all I need are about 90 characters to
|
|
display my full string, so run `config max-string-len 90` from the `dlv`
|
|
session.
|
|
|
|
```go
|
|
(dlv) config max-string-len 90
|
|
(dlv) print diagnostics.Solutions[0]
|
|
"295743861\n431865972\n876192543\n387459216\n612387495\n549216738\n763524189\n928671354\n154938627"
|
|
```
|
|
|
|
Now I can see the entire string instead of the truncated version.
