Jetpack Compose Rust Parser
Link: https://crates.io/crates/compose_parser Docs: https://docs.rs/compose_parser/latest/compose_parser/
Brief Describe
- Rust parser created to parse the Jetpack Compose Text / Image View and get all text fields and images
- It is important that the function starts with @Composable and has any name
- Plus use Kotlin syntax
Grammar
compose_function = { function_declaration }
function_declaration = { "@Composable\nfun " ~ function_name ~ "() " ~ block }
function_name = { identifier }
block = { "{\n" ~ statement* ~ "}" }
statement = { text_function | image_function }
text_function = { " Text(text = " ~ string ~ ")\n" }
image_function = { " Image(image = " ~ string_image ~ ")\n" }
string = { "\"" ~ (ASCII_ALPHANUMERIC | " ")* ~ "\"" }
string_image = { "\"" ~ ASCII_ALPHANUMERIC* ~ ".png\"" }
identifier = { ASCII_ALPHA ~ (ASCII_ALPHANUMERIC | "_")* }
- compose_function - main function that contains all functions
- function_declaration - function declaration with name and block

- text_function - text function with string
