## Configuration ## Configuration
Configuring mstdn-ebooks is accomplished by editing `config.json`. If you want to use a different file for configuration, specify it with the `--cfg` argument. For example, if you want to use `/home/lynne/c.json` instead, you would run `python3 main.py --cfg /home/lynne/c.json` instead of just `python3 main.py` Configuring mstdn-ebooks is accomplished by editing `config.json`.

| strip_paired_punctuation | false | If true, mstdn-ebooks will remove punctuation that commonly appears in pairs, like " and ().

| limit_length | false | If true, the sentence length will be random between `length_lower_limit` and `length_upper_limit` |
| length_lower_limit | 5 | The lower bound in the random number range above. Only matters if `limit_length` is true. |
| length_upper_limit | 50 | The upper bound in the random number range above. Can be the same as `length_lower_limit` to disable randomness. Only matters if `limit_length` is true. |
| overlap_ratio_enabled | false | If true, checks the output's similarity to the original posts. |
| overlap_ratio | 0.7 | The ratio that determins if the output is too similar to original or not. With decreasing ratio, both the interestingness of the output and the likelihood of failing to create output increases. Only matters if `overlap_ratio_enabled` is true. |
