# GDB Pretty Printer
|
|
|
|
File [nlohmann-json.py](nlohmann-json.py) contains a pretty printer for GDB for JSON values of this library. It was originally published as [Gist](https://gist.github.com/ssbssa/60da5339c6e6036b2afce17de06050ea#file-nlohmann-json-py) by [Hannes Domani](https://github.com/ssbssa).
|
|
|
|
## How to use
|
|
|
|
- Add line
|
|
|
|
```
|
|
source /path/to/nlohmann-json.py
|
|
```
|
|
|
|
to `~/.gdbinit`. Note you must replace `/path/to` with whatever path you stored file `nlohmann-json.py`.
|
|
- In GDB, debug as usual. When you want to pretty-print a JSON value `var`, type
|
|
|
|
```
|
|
p -pretty on -array on -- var
|
|
```
|
|
|
|
The result should look like
|
|
|
|
```
|
|
$1 = std::map with 5 elements = {
|
|
["Baptiste"] = std::map with 1 element = {
|
|
["first"] = "second"
|
|
},
|
|
["Emmanuel"] = std::vector of length 3, capacity 3 = {
|
|
3,
|
|
"25",
|
|
0.5
|
|
},
|
|
["Jean"] = 0.7,
|
|
["Zorg"] = std::map with 8 elements = {
|
|
["array"] = std::vector of length 3, capacity 3 = {
|
|
1,
|
|
0,
|
|
2
|
|
},
|
|
["awesome_str"] = "bleh",
|
|
["bool"] = true,
|
|
["flex"] = 0.2,
|
|
["float"] = 5.22,
|
|
["int"] = 5,
|
|
["nested"] = std::map with 1 element = {
|
|
["bar"] = "barz"
|
|
},
|
|
["trap "] = "you fell"
|
|
},
|
|
["empty"] = nlohmann::detail::value_t::null
|
|
}
|
|
```
|
|
|
|
Requires Python 3.9+. Last tested with GDB 12.1.
