# How to use

## csv-core

- `Converter` A basic CSV converter
- `CsvableBuilder` Support for converting Scala `case class` to CSV in a custom way.
- `ScalableBuilder` Support for converting CSV to Scala `case class` in a custom way.
- Zero dependency, type-safe

```scala
"org.bitlap" %% "smt-csv-core" % "<VERSION>" // since 0.4.4 
```

## csv-derive

- `DeriveCsvConverter` 为Scala`case class`自动派生`Converter`实例

```scala
"org.bitlap" %% "smt-csv-derive" % "<VERSION>" // since 0.4.4 
```

## tools

- `@toString`
- `@json`
- `@builder`
- `@log`
- `@apply`
- `@constructor`
- `@equalsAndHashCode`
- `@jacksonEnum`
- `@elapsed`
- `@javaCompatible`
- `ProcessorCreator`

> The intellij plugin named `Scala-Macro-Tools` in marketplace.

```scala
"org.bitlap" %% "smt-tools" % "<VERSION>" // named smt-tools since 0.4.0 
```

## cacheable-core

A cache like Spring `@Cacheable` and `@cacheEvict` based on zio. It has no implementation of storage media.

- `@cacheable` / `Cache.apply`
- `@cacheEvict` / `Cache.evict`

```scala
// cache API, include dependencies: zio, zio-streams, zio-logging
"org.bitlap" %% "smt-cacheable-core" % "<VERSION>" // not support Scala2.11.x
```

## cacheable-redis

A distributed cache based on zio and zio-redis. It needs `cacheable-core` module.

> TODO Not unavailable, no distributed lock

```scala
// distributed cache, include dependencies: zio-redis, config, zio-schema, zio-schema-json, optional (zio-schema-derivation for case class)
// dependsOn `smt-cacheable-core`
"org.bitlap" %% "smt-cacheable-redis" % "<VERSION>" // not support Scala2.11.x
```

## cacheable-caffeine

A memory cache based on zio and caffeine. It needs `cacheable-core` module.

```scala
// local cache, include dependencies: config, caffeine
// dependsOn `smt-cacheable-core`
"org.bitlap" %% "smt-cacheable-caffeine" % "<VERSION>" // not support Scala2.11.x
```

The artefacts have been uploaded to Maven Central. Importing the library into your build system (e.g gradle, sbt), is not enough. You need to follow an extra step.

| Scala 2.11                   | Scala 2.12                   | Scala 2.13                                          |
| ---------------------------- | ---------------------------- | --------------------------------------------------- |
| Import macro paradise plugin | Import macro paradise plugin | Enable compiler flag `-Ymacro-annotations` required |

```scala
addCompilerPlugin("org.scalamacros" % "paradise_<your-scala-version>" % "<plugin-version>")
```

Where `<your-scala-version>` must be the full scala version. For example 2.12.13, and not 2.12.

If that doesn't work, google for alternatives.

In version scala`2.13.x`, the functionality of macro paradise has been included in the scala compiler directly. However,
you must still enable the compiler flag `-Ymacro-annotations`.
