## Installing third-party parser plugins {#parser-plugins}
|
||||
|
||||
Third-party parser plugins extend Paperless-ngx to support additional file
|
||||
formats. A plugin is a Python package that advertises itself under the
|
||||
`paperless_ngx.parsers` entry point group. Refer to the
|
||||
[developer documentation](development.md#making-custom-parsers) for how to
|
||||
create one.
|
||||
|
||||
!!! warning "Third-party plugins are not officially supported"
|
||||
|
||||
The Paperless-ngx maintainers do not provide support for third-party
|
||||
plugins. Issues caused by or requiring changes to a third-party plugin
|
||||
will be closed without further investigation. Always reproduce problems
|
||||
with all plugins removed before filing a bug report.
|
||||
|
||||
### Docker
|
||||
|
||||
Use a [custom container initialization script](#custom-container-initialization)
|
||||
to install the package before the webserver starts. Create a shell script and
|
||||
mount it into `/custom-cont-init.d`:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# /path/to/my/scripts/install-parsers.sh
|
||||
|
||||
pip install my-paperless-parser-package
|
||||
```
|
||||
|
||||
Mount it in your `docker-compose.yml`:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
webserver:
|
||||
# ...
|
||||
volumes:
|
||||
- /path/to/my/scripts:/custom-cont-init.d:ro
|
||||
```
|
||||
|
||||
The script runs as `root` before the webserver starts, so the package will be
|
||||
available when Paperless-ngx discovers plugins at startup.
|
||||
|
||||
### Bare metal
|
||||
|
||||
Install the package into the same Python environment that runs Paperless-ngx.
|
||||
If you followed the standard bare-metal install guide, that is the `paperless`
|
||||
user's environment:
|
||||
|
||||
```bash
|
||||
sudo -Hu paperless pip3 install my-paperless-parser-package
|
||||
```
|
||||
|
||||
If you are using `uv` or a virtual environment, activate it first and then run:
|
||||
|
||||
```bash
|
||||
uv pip install my-paperless-parser-package
|
||||
# or
|
||||
pip install my-paperless-parser-package
|
||||
```
|
||||
|
||||
Restart all Paperless-ngx services after installation so the new plugin is
|
||||
discovered.
|
||||
|
||||
### Verifying installation
|
||||
|
||||
On the next startup, check the application logs for a line confirming
|
||||
discovery:
|
||||
|
||||
```
|
||||
Loaded third-party parser 'My Parser' v1.0.0 by Acme Corp (entrypoint: 'my_parser').
|
||||
```
|
||||
|
||||
If this line does not appear, verify that the package is installed in the
|
||||
correct environment and that its `pyproject.toml` declares the
|
||||
`paperless_ngx.parsers` entry point.

## Extending Paperless-ngx
|
||||
|
||||
Paperless-ngx does not have any fancy plugin systems and will probably never
|
||||
have. However, some parts of the application have been designed to allow
|
||||
easy integration of additional features without any modification to the
|
||||
base code.
|
||||
Paperless-ngx supports third-party document parsers via a Python entry point
|
||||
plugin system. Plugins are distributed as ordinary Python packages and
|
||||
discovered automatically at startup — no changes to the Paperless-ngx source
|
||||
are required.
|
||||
|
||||
!!! warning "Third-party plugins are not officially supported"
|
||||
|
||||
The Paperless-ngx maintainers do not provide support for third-party
|
||||
plugins. Issues that are caused by or require changes to a third-party
|
||||
plugin will be closed without further investigation. If you believe you
|
||||
have found a bug in Paperless-ngx itself (not in a plugin), please
|
||||
reproduce it with all third-party plugins removed before filing an issue.

|
||||
Paperless-ngx uses parsers to add documents. A parser is responsible for:
|
||||
|
||||
- Retrieving the content from the original
|
||||
- Creating a thumbnail
|
||||
- _optional:_ Retrieving a created date from the original
|
||||
- _optional:_ Creating an archived document from the original
|
||||
- Extracting plain-text content from the document
|
||||
- Generating a thumbnail image
|
||||
- _optional:_ Detecting the document's creation date
|
||||
- _optional:_ Producing a searchable PDF archive copy
|
||||
|
||||
Custom parsers can be added to Paperless-ngx to support more file types. In
|
||||
order to do that, you need to write the parser itself and announce its
|
||||
existence to Paperless-ngx.
|
||||
Custom parsers are distributed as ordinary Python packages and registered
|
||||
via a [setuptools entry point](https://setuptools.pypa.io/en/latest/userguide/entry_point.html).
|
||||
No changes to the Paperless-ngx source are required.
|
||||
|
||||
The parser itself must extend `documents.parsers.DocumentParser` and
|
||||
must implement the methods `parse` and `get_thumbnail`. You can provide
|
||||
your own implementation to `get_date` if you don't want to rely on
|
||||
Paperless-ngx' default date guessing mechanisms.
|
||||
#### 1. Implementing the parser class
|
||||
|
||||
Your parser must satisfy the `ParserProtocol` structural interface defined in
|
||||
`paperless.parsers`. The simplest approach is to write a plain class — no base
|
||||
class is required, only the right attributes and methods.
|
||||
|
||||
**Class-level identity attributes**
|
||||
|
||||
The registry reads these before instantiating the parser, so they must be
|
||||
plain class attributes (not instance attributes or properties):
|
||||
|
||||
```python
|
||||
class MyCustomParser(DocumentParser):
|
||||
|
||||
def parse(self, document_path, mime_type):
|
||||
# This method does not return anything. Rather, you should assign
|
||||
# whatever you got from the document to the following fields:
|
||||
|
||||
# The content of the document.
|
||||
self.text = "content"
|
||||
|
||||
# Optional: path to a PDF document that you created from the original.
|
||||
self.archive_path = os.path.join(self.tempdir, "archived.pdf")
|
||||
|
||||
# Optional: "created" date of the document.
|
||||
self.date = get_created_from_metadata(document_path)
|
||||
|
||||
def get_thumbnail(self, document_path, mime_type):
|
||||
# This should return the path to a thumbnail you created for this
|
||||
# document.
|
||||
return os.path.join(self.tempdir, "thumb.webp")
|
||||
class MyCustomParser:
|
||||
name = "My Format Parser" # human-readable name shown in logs
|
||||
version = "1.0.0" # semantic version string
|
||||
author = "Acme Corp" # author / organisation
|
||||
url = "https://example.com/my-parser" # docs or issue tracker
|
||||
```
|
||||
|
||||
If you encounter any issues during parsing, raise a
|
||||
`documents.parsers.ParseError`.
|
||||
**Declaring supported MIME types**
|
||||
|
||||
The `self.tempdir` directory is a temporary directory that is guaranteed
|
||||
to be empty and removed after consumption finished. You can use that
|
||||
directory to store any intermediate files and also use it to store the
|
||||
thumbnail / archived document.
|
||||
|
||||
After that, you need to announce your parser to Paperless-ngx. You need to
|
||||
connect a handler to the `document_consumer_declaration` signal. Have a
|
||||
look in the file `src/paperless_tesseract/apps.py` on how that's done.
|
||||
The handler is a method that returns information about your parser:
|
||||
Return a `dict` mapping MIME type strings to preferred file extensions
|
||||
(including the leading dot). Paperless-ngx uses the extension when storing
|
||||
archive copies and serving files for download.
|
||||
|
||||
```python
|
||||
def myparser_consumer_declaration(sender, **kwargs):
|
||||
@classmethod
|
||||
def supported_mime_types(cls) -> dict[str, str]:
|
||||
return {
|
||||
"parser": MyCustomParser,
|
||||
"weight": 0,
|
||||
"mime_types": {
|
||||
"application/pdf": ".pdf",
|
||||
"image/jpeg": ".jpg",
|
||||
}
|
||||
"application/x-my-format": ".myf",
|
||||
"application/x-my-format-alt": ".myf",
|
||||
}
|
||||
```
|
||||
|
||||
- `parser` is a reference to a class that extends `DocumentParser`.
|
||||
- `weight` is used whenever two or more parsers are able to parse a
|
||||
file: The parser with the higher weight wins. This can be used to
|
||||
override the parsers provided by Paperless-ngx.
|
||||
- `mime_types` is a dictionary. The keys are the mime types your
|
||||
parser supports and the value is the default file extension that
|
||||
Paperless-ngx should use when storing files and serving them for
|
||||
download. We could guess that from the file extensions, but some
|
||||
mime types have many extensions associated with them and the Python
|
||||
methods responsible for guessing the extension do not always return
|
||||
the same value.
|
||||
**Scoring**
|
||||
|
||||
## Using Visual Studio Code devcontainer
|
||||
When more than one parser can handle a file, the registry calls `score()` on
|
||||
each candidate and picks the one with the highest result and equal scores favor third-party parsers over built-ins. Return `None` to
|
||||
decline handling a file even though the MIME type is listed as supported (for
|
||||
example, when a required external service is not configured).
|
||||
|
||||
Another easy way to get started with development is to use Visual Studio
|
||||
Code devcontainers. This approach will create a preconfigured development
|
||||
environment with all of the required tools and dependencies.
|
||||
[Learn more about devcontainers](https://code.visualstudio.com/docs/devcontainers/containers).
|
||||
The .devcontainer/vscode/tasks.json and .devcontainer/vscode/launch.json files
|
||||
contain more information about the specific tasks and launch configurations (see the
|
||||
non-standard "description" field).
|
||||
| Score | Meaning |
|
||||
| ------ | --------------------------------------------------------------------------------- |
|
||||
| `None` | Decline — do not handle this file |
|
||||
| `10` | Default priority used by all built-in parsers |
|
||||
| `20` | Priority used by the remote OCR built-in parser, allowing it to replace Tesseract |
|
||||
| `> 10` | Override a built-in parser for the same MIME type |
|
||||
|
||||
To get started:
|
||||
```python
|
||||
@classmethod
|
||||
def score(
|
||||
cls,
|
||||
mime_type: str,
|
||||
filename: str,
|
||||
path: "Path | None" = None,
|
||||
) -> int | None:
|
||||
# Inspect filename or file bytes here if needed.
|
||||
return 10
|
||||
```
|
||||
|
||||
1. Clone the repository on your machine and open the Paperless-ngx folder in VS Code.
|
||||
**Archive and rendition flags**
|
||||
|
||||
2. VS Code will prompt you with "Reopen in container". Do so and wait for the environment to start.
|
||||
```python
|
||||
@property
|
||||
def can_produce_archive(self) -> bool:
|
||||
"""True if parse() can produce a searchable PDF archive copy."""
|
||||
return True # or False if your parser doesn't produce PDFs
|
||||
|
||||
3. In case your host operating system is Windows:
|
||||
- The Source Control view in Visual Studio Code might show: "The detected Git repository is potentially unsafe as the folder is owned by someone other than the current user." Use "Manage Unsafe Repositories" to fix this.
|
||||
- Git might have detecteded modifications for all files, because Windows is using CRLF line endings. Run `git checkout .` in the containers terminal to fix this issue.
|
||||
@property
|
||||
def requires_pdf_rendition(self) -> bool:
|
||||
"""True if the original format cannot be displayed by a browser
|
||||
(e.g. DOCX, ODT) and the PDF output must always be kept."""
|
||||
return False
|
||||
```
|
||||
|
||||
4. Initialize the project by running the task **Project Setup: Run all Init Tasks**. This
|
||||
will initialize the database tables and create a superuser. Then you can compile the front end
|
||||
for production or run the frontend in debug mode.
|
||||
**Context manager — temp directory lifecycle**
|
||||
|
||||
5. The project is ready for debugging, start either run the fullstack debug or individual debug
|
||||
processes. Yo spin up the project without debugging run the task **Project Start: Run all Services**
|
||||
Paperless-ngx always uses parsers as context managers. Create a temporary
|
||||
working directory in `__enter__` (or `__init__`) and remove it in `__exit__`
|
||||
regardless of whether an exception occurred. Store intermediate files,
|
||||
thumbnails, and archive PDFs inside this directory.

||||

||||

|
||||
self._tempdir = Path(

|
||||
)
|
||||

||||

|
||||
|
||||

|
||||
return self

|
||||
self,
|

||||

|
||||
) -> None:
|
||||
shutil.rmtree(self._tempdir, ignore_errors=True)
|
||||
```
|
||||
|
||||
**Optional context — `configure()`**
|
||||
|
||||
The consumer calls `configure()` with a `ParserContext` after instantiation
|
||||
and before `parse()`. If your parser doesn't need context, a no-op
|
||||
implementation is fine:
|
||||
|
||||
```python
|
||||
from paperless.parsers import ParserContext
|
||||
|
||||
def configure(self, context: ParserContext) -> None:
|
||||
pass # override if you need context.mailrule_id, etc.
|
||||
```
|
||||
|
||||
**Parsing**

||||
|
||||

|
||||
results in instance attributes and expose them via the accessor methods below.

||||

|
||||

to a WebP image inside `self._tempdir`. The image should be roughly 500 × 700
|
||||
pixels.
|
||||
|
||||
```python
|
||||
def get_thumbnail(self, document_path: Path, mime_type: str) -> Path:
|
||||
thumb = self._tempdir / "thumb.webp"

||||
```
|
||||

||||
**Optional methods**
|
||||

||||
These are called by the API on demand, not during the consumption pipeline.

|
||||

|
||||
self,
|
||||
document_path: Path,
|
||||
mime_type: str,
|
||||
) -> "list[MetadataEntry]":
|
||||
# Must never raise. Return [] if metadata cannot be read.
|
||||
from paperless.parsers import MetadataEntry
|
||||
return [
|
||||

|
||||
namespace="https://example.com/ns/",

||||
prefix="ex",
|

key="Author",
|
||||
value="Alice",
|
||||
)
|
||||
]
|
||||
```
|
||||
|
||||
#### 2. Registering via entry point
|
||||
|
||||
Add the following to your package's `pyproject.toml`. The key (left of `=`)
|
||||
is an arbitrary name used only in log output; the value is the
|
||||
`module:ClassName` import path.
|
||||
|
||||
```toml
|
||||
[project.entry-points."paperless_ngx.parsers"]
|
||||
my_parser = "my_package.parsers:MyCustomParser"
|
||||
```
|
||||
|
||||
Install your package into the same Python environment as Paperless-ngx (or
|
||||
add it to the Docker image), and the parser will be discovered automatically
|
||||
on the next startup. No configuration changes are needed.
|
||||
|
||||
To verify discovery, check the application logs at startup for a line like:
|
||||
|
||||
```
|
||||
Loaded third-party parser 'My Format Parser' v1.0.0 by Acme Corp (entrypoint: 'my_parser').
|
||||
```
|
||||
|
||||
#### 3. Utilities
|
||||
|
||||
`paperless.parsers.utils` provides helpers you can import directly:
|
||||
|
||||
| Function | Description |
|
||||
| --------------------------------------- | ---------------------------------------------------------------- |
|
||||
| `read_file_handle_unicode_errors(path)` | Read a file as UTF-8, replacing invalid bytes instead of raising |
|
||||
| `get_page_count_for_pdf(path)` | Count pages in a PDF using pikepdf |
|
||||
| `extract_pdf_metadata(path)` | Extract XMP metadata from a PDF as a `list[MetadataEntry]` |

### Developing date parser plugins
|
||||
|

## Using Visual Studio Code devcontainer
|
||||
|
||||
Another easy way to get started with development is to use Visual Studio
|
||||
Code devcontainers. This approach will create a preconfigured development
|
||||
environment with all of the required tools and dependencies.
|
||||
[Learn more about devcontainers](https://code.visualstudio.com/docs/devcontainers/containers).
|
||||
The .devcontainer/vscode/tasks.json and .devcontainer/vscode/launch.json files
|
||||
contain more information about the specific tasks and launch configurations (see the
|
||||
non-standard "description" field).
|
||||
|
||||
To get started:
|
||||
|
||||
1. Clone the repository on your machine and open the Paperless-ngx folder in VS Code.
|
||||
|
||||
2. VS Code will prompt you with "Reopen in container". Do so and wait for the environment to start.
|
||||
|
||||
3. In case your host operating system is Windows:
|
||||
- The Source Control view in Visual Studio Code might show: "The detected Git repository is potentially unsafe as the folder is owned by someone other than the current user." Use "Manage Unsafe Repositories" to fix this.
|
||||
- Git might have detecteded modifications for all files, because Windows is using CRLF line endings. Run `git checkout .` in the containers terminal to fix this issue.
|
||||
|
||||
4. Initialize the project by running the task **Project Setup: Run all Init Tasks**. This
|
||||
will initialize the database tables and create a superuser. Then you can compile the front end
|
||||
for production or run the frontend in debug mode.
|
||||
|
||||
5. The project is ready for debugging, start either run the fullstack debug or individual debug

# Search Index (Whoosh -> Tantivy)
|
||||
|
||||
The full-text search backend has been replaced with [Tantivy](https://github.com/quickwit-oss/tantivy).
|
||||
The index format is incompatible with Whoosh, so **the search index is automatically rebuilt from
|
||||
scratch on first startup after upgrading**. No manual action is required for the rebuild itself.
|
||||
|
||||
### Note and custom field search syntax
|
||||
|
||||
The old Whoosh index exposed `note` and `custom_field` as flat text fields that were included in
|
||||
unqualified searches (e.g. just typing `invoice` would match note content). With Tantivy these are
|
||||
now structured JSON fields accessed via dotted paths:
|
||||
|
||||
| Old syntax | New syntax |
|
||||
| -------------------- | --------------------------- |
|
||||
| `note:query` | `notes.note:query` |
|
||||
| `custom_field:query` | `custom_fields.value:query` |
|
||||
|
||||
**Saved views are migrated automatically.** Any saved view filter rule that used an explicit
|
||||
`note:` or `custom_field:` field prefix in a fulltext query is rewritten to the new syntax by a
|
||||
data migration that runs on upgrade.
|
||||
|
||||
**Unqualified queries are not migrated.** If you had a saved view with a plain search term (e.g.
|
||||
`invoice`) that happened to match note content or custom field values, it will no longer return
|
||||
those matches. Update those queries to use the explicit prefix, for example:
|
||||
|
||||
```
|
||||
invoice OR notes.note:invoice OR custom_fields.value:invoice
|
||||
```
|
||||
|
||||
Custom field names can also be searched with `custom_fields.name:fieldname`.

- **Accent-insensitive**: searching `resume` also finds `résumé`, `cafe` finds `café`.
|
||||
- **Separator-agnostic**: punctuation and separators are stripped during indexing, so
|
||||
searching a partial number like `1312` finds documents containing `A-1312/B`.

#### Searching custom fields
|
||||
|
||||
Custom field values are included in the full-text index, so a plain search
|
||||
already matches documents whose custom field values contain your search terms.
|
||||
To narrow by field name or value specifically:
|
||||
|
||||
```
|
||||
custom_fields.value:policy
|
||||
custom_fields.name:"Contract Number"
|
||||
custom_fields.name:Insurance custom_fields.value:policy
|
||||
```
|
||||
|
||||
- `custom_fields.value` matches against the value of any custom field.
|
||||
- `custom_fields.name` matches the name of the field (use quotes for multi-word names).
|
||||
- Combine both to find documents where a specific named field contains a specific value.
|
||||
|
||||
Because separators are stripped during indexing, individual parts of formatted
|
||||
codes are searchable on their own. A value stored as `A-1312/99.50` produces the
|
||||
tokens `a`, `1312`, `99`, `50` — each searchable independently:
|
||||
|
||||
```
|
||||
custom_fields.value:1312
|
||||
custom_fields.name:"Contract Number" custom_fields.value:1312
|
||||
```
|
||||
|
||||
!!! note
|
||||
|
||||
Inexact terms are hard for search indexes. These queries might take a
|
||||
while to execute. That's why paperless offers auto complete and query
|
||||
correction.
|
||||
Custom date fields do not support relative date syntax (e.g. `[now to 2 weeks]`).
|
||||
For date ranges on custom date fields, use the document list filters in the web UI.
|
||||
|
||||
#### Searching notes
|
||||
|
||||
Notes content is included in full-text search automatically. To search
|
||||
by note author or content specifically:
|
||||
|
||||
```
|
||||
notes.user:alice
|
||||
notes.note:reminder
|
||||
notes.user:alice notes.note:insurance
|
||||
```
|
||||
