Spaces before and after the name and argument are ignored. Multiple arguments are separated by spaces. One set of quotes will be removed, preserving spaces (the same way the command line works). Boolean options can be `true`, `on`, `1`, `yes`, `enable`; or `false`, `off`, `0`, `no`, `disable` (case insensitive). Sections (and `.` separated names) are treated as subcommands (note: this does not necessarily mean that subcommand was passed, it just sets the "defaults"). You cannot set positional-only arguments. Subcommands can be triggered from configuration files if the `configurable` flag was set on the subcommand. Then the use of `[subcommand]` notation will trigger a subcommand and cause it to act as if it were on the command line.

### Trivial JSON configuration example
|
||||
|
||||
```JSON
|
||||
{
|
||||
"test": 56,
|
||||
"testb": "test",
|
||||
"flag": true
|
||||
}
|
||||
```
|
||||
|
||||
The parser can handle these structures with only a minor tweak
|
||||
|
||||
```cpp
|
||||
app.get_config_formatter_base()->valueSeparator(':');
|
||||
```
|
||||
|
||||
The open and close brackets must be on a separate line and the comma gets interpreted as an array separator but since no values are after the comma they get ignored as well. This will not support multiple layers or sections or any other moderately complex JSON, but can work if the input file is simple.
|
||||
|
||||
## Triggering Subcommands
|
||||
|
||||
Configuration files can be used to trigger subcommands if a subcommand is set to configure. By default configuration file just set the default values of a subcommand. But if the `configure()` option is set on a subcommand then the if the subcommand is utilized via a `[subname]` block in the configuration file it will act as if it were called from the command line. Subsubcommands can be triggered via `[subname.subsubname]`. Using the `[[subname]]` will be as if the subcommand were triggered multiple times from the command line. This functionality can allow the configuration file to act as a scripting file.
|
||||
|
||||
For custom configuration files this behavior can be triggered by specifying the parent subcommands in the structure and `++` as the name to open a new subcommand scope and `--` to close it. These names trigger the different callbacks of configurable subcommands.
|
||||
|
||||
## Stream parsing
|
||||
|
||||
In addition to the regular parse functions a `parse_from_stream(std::istream &input)` is available to directly parse a stream operator. For example to process some arguments in an already open file stream. The stream is fed directly in the config parser so bypasses the normal command line parsing.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The config file input works with any form of the option given: Long, short, positional, or the environment variable name. When generating a config file it will create a name in following priority.
