## Generate a Parser
Now that the grammar is defined, generate a parser with PSI classes via <control>Generate Parser Code</control> from the context menu on the <path>Simple.bnf</path> file.
This step generates a parser and PSI elements in the <path>/src/main/gen</path> folder of the project.
Mark this folder as <control>Generated Sources Root</control> and make sure everything compiles without errors.

## Add Generated Sources Root
To include the sources generated into <path>/src/main/gen</path>, the project's `sourceSets` must be expanded by inserting the following line in the project's <path>build.gradle</path> file:
```groovy
sourceSets.main.java.srcDirs 'src/main/gen'
```
Or the following line in the project's <path>build.gradle.kts</path> file:
```kotlin
sourceSets["main"].java.srcDirs("src/main/gen")
```
Reload the Gradle project for changes to take effect and build the project.

## Required Project Configuration Change
The previous tutorial step [Grammar and Parser](grammar_and_parser.md), and this page, generate source files in the directory <path>src/main/gen</path>.
To include those files, the project's `sourceSets` must be expanded by inserting the following line in the project's <path>build.gradle</path> file:
```groovy
sourceSets.main.java.srcDirs 'src/main/gen'
```
Or the following line in the project's <path>build.gradle.kts</path> file:
```kotlin
sourceSets["main"].java.srcDirs("src/main/gen")
```

## Define a Lexer
Define a <path>Simple.flex</path> file with rules for the Simple Language lexer, as demonstrated in `org.intellij.sdk.language.Simple.flex`.
