### CLI

casparser also comes with a command-line interface that prints summary of parsed
portfolio in a wide variety of formats.

```
Usage: casparser [-o output_file.json|output_file.csv] [-p password] [-s] [-a] CAS_PDF_FILE

  -o, --output FILE               Output file path. Saves the parsed data as json or csv
                                  depending on the file extension. For other extensions, the
                                  summary output is saved. [See note below]

  -s, --summary                   Print Summary of transactions parsed.
  -p PASSWORD                     CAS password
  -a, --include-all               Include schemes with zero valuation in the
                                  summary output
  -g, --gains                     Generate Capital Gains Report (BETA)
  --gains-112a ask|FY2020-21      Generate Capital Gains Report - 112A format for
                                  a given financial year - Use 'ask' for a prompt
                                  from available options (BETA)
  --force-pdfminer                Force PDFMiner parser even if MuPDF is
                                  detected

  --version                       Show the version and exit.
  -h, --help                      Show this message and exit.
```

#### CLI examples
```
# Print portfolio summary
casparser /path/to/cas.pdf -p password

# Print portfolio and capital gains summary
casparser /path/to/cas.pdf -p password -g

# Save parsed data as a json file
casparser /path/to/cas.pdf -p password -o pdf_parsed.json

# Save parsed data as a csv file
casparser /path/to/cas.pdf -p password -o pdf_parsed.csv

# Save capital gains transactions in csv files (pdf_parsed-gains-summary.csv and
# pdf_parsed-gains-detailed.csv)
casparser /path/to/cas.pdf -p password -g -o pdf_parsed.csv

```

**Note:** `casparser cli` supports two special output file formats [-o _file.json_ / _file.csv_]
1. `json` - complete parsed data is exported in json format (including investor info)
2. `csv` - Summary info is exported in csv format if the input file is a summary statement or if
   a summary flag (`-s/--summary`) is passed as argument to the CLI. Otherwise, full
   transaction history is included in the export.
   If `-g` flag is present, two additional files '{basename}-gains-summary.csv',
   '{basename}-gains-detailed.csv' are created with the capital-gains data.
3. any other extension - The summary table is saved in the file.


#### Demo

![demo](https://raw.githubusercontent.com/codereverser/casparser/main/assets/demo.jpg)

## ISIN & AMFI code support

Since v0.4.3, `casparser` includes support for identifying ISIN and AMFI code for the parsed schemes
via the helper module [casparser-isin](https://github.com/codereverser/casparser-isin/). If the parser
fails to assign ISIN or AMFI codes to a scheme, try updating the local ISIN database by

```shell
casparser-isin --update
```

If it still fails, please raise an issue at [casparser-isin](https://github.com/codereverser/casparser-isin/issues/new) with the
failing scheme name(s).

CASParser is distributed under MIT license by default. However enabling the optional dependency
`mupdf/fast` would imply the use of [PyMuPDF](https://github.com/pymupdf/PyMuPDF) /
