# Configure Application

All available options can be printed via the `--help` flag.

```
Usage: suanPan [--help] [--version] [--no-color] [--no-print] [--no-update] [--verbose] [--input-file INPUT_FILE_PATH] [--output-file OUTPUT_FILE_PATH]

Optional arguments:
  -h, --help                                    show this help message and exit 
  -v, --version                                 show version information and exit 
  -nc, --no-color                               suppress colors in terminal output 
  -np, --no-print                               suppress (most) terminal output 
  -nu, --no-update                              skip new version check on startup 
  -vb, --verbose                                enable (very) verbose terminal output 
  -f, --input, --input-file INPUT_FILE_PATH     specify path to the file containing input analysis 
  -o, --output, --output-file OUTPUT_FILE_PATH  specify path to the file for terminal output redirection 
```

## Disable New Version Check

Some distributions are bundled with an updater that checks for new versions of the application on startup and allows you to download new archives if necessary. In some fully automated environments, one can disable the check via the `-nu` option.

```shell
suanpan -nu -f <your_input_model.sp>
```

## Disable Color Output

By default, the console output is coloured to make it more readable. If the console output is redirected to a file, the ANSI color codes will be included in the file. To disable coloured output, use the `-nc` option.

```shell
suanpan -nc -f <your_input_model.sp>
```

The ANSI color codes can be properly rendered using, for example, [bat](https://github.com/sharkdp/bat).

## Redirect Console Output

By default, the console output is printed to the standard output. To redirect the output to a file, use the `-o` option.

```shell
suanpan -f <your_input_model.sp> -o <your_output_file>
```

## Verbose Output

With the release build, only info/warning/error/fatal messages will be printed. To print debug messages, use the `-vb` option.

```shell
suanpan -vb -f <your_input_model.sp>
```

## Disable Output

If the model has been checked, output can be disabled to speed up the analysis. To disable the output, use the `-np` option.

```shell
suanpan -np -f <your_input_model.sp>
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tlcfem.gitbook.io/suanpan-manual/basic/config.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
