Removed all file graph uses of :block/namespace, :block/file, :block/type and :block/properties except for graph-parser which still uses them for db importer. Removed all uses of :block/format except for graph-parser and src/main/frontend

## Description
|
|
|
|
This library provides an API to the
|
|
frontend([datascript](https://github.com/tonsky/datascript)) and
|
|
backend([SQLite](https://www.sqlite.org/index.html)) databases from the Logseq
|
|
app and the CLI. The majority of this library is focused on supporting DB graphs
|
|
but there are a few namespaces that support file graphs. This library is
|
|
compatible with ClojureScript and with
|
|
[nbb-logseq](https://github.com/logseq/nbb-logseq) to respectively provide
|
|
frontend and commandline functionality.
|
|
|
|
## API
|
|
|
|
This library is under the parent namespace `logseq.db`. It provides the following namespaces:
|
|
* `logseq.db` - main entry point serving both file and DB graphs
|
|
* `logseq.db.frontend.*` - frontend namespaces for DB graphs
|
|
* `logseq.db.sqlite.*` - backend/sqlite namespaces for DB graphs
|
|
* `logseq.db.common.*` - namespaces for both file and DB graphs
|
|
|
|
## Usage
|
|
|
|
See the frontend for example usage.
|
|
|
|
## Dev
|
|
|
|
This follows the practices that [the Logseq frontend
|
|
follows](/docs/dev-practices.md). Most of the same linters are used, with
|
|
configurations that are specific to this library. See [this library's CI
|
|
file](/.github/workflows/deps-db.yml) for linting examples.
|
|
|
|
### Setup
|
|
|
|
To run linters and tests, you'll want to install yarn dependencies once:
|
|
```
|
|
yarn install
|
|
```
|
|
|
|
This step is not needed if you're just running the application.
|
|
|
|
### Testing
|
|
|
|
Testing is done with nbb-logseq and
|
|
[nbb-test-runner](https://github.com/nextjournal/nbb-test-runner). Some basic
|
|
usage:
|
|
|
|
```
|
|
# Run all tests
|
|
$ yarn test
|
|
# List available options
|
|
$ yarn test -H
|
|
# Run tests with :focus metadata flag
|
|
$ yarn test -i focus
|
|
```
|
|
### Datalog linting
|
|
|
|
Datalog rules for the client are linted through a script that also uses the datalog-parser. To run this linter:
|
|
```
|
|
bb lint:rules
|
|
```
|
|
|
|
### Managing dependencies
|
|
|
|
The package.json dependencies are just for testing and should be updated if there is
|
|
new behavior to test.
|
|
|
|
The deps.edn dependencies are used by both ClojureScript and nbb-logseq. Their
|
|
versions should be backwards compatible with each other with priority given to
|
|
the frontend. _No new dependency_ should be introduced to this library without
|
|
an understanding of the tradeoffs of adding this to nbb-logseq.
