Struct FileTreeGenerator 

pub struct FileTreeGenerator { /* private fields */ }

File tree generator for creating directory structures from templates

Takes a FileTreeTemplate and a TemplateContext, then generates the corresponding file tree in the filesystem with variable substitution.

Examples

use ggen_core::templates::generator::FileTreeGenerator;
use ggen_core::templates::{FileTreeTemplate, TemplateContext};
use ggen_core::templates::format::TemplateFormat;
use std::path::Path;

let format = TemplateFormat::new("my-template");
let template = FileTreeTemplate::new(format);
let context = TemplateContext::new();

let mut generator = FileTreeGenerator::new(template, context, Path::new("output"));
let result = generator.generate()?;

Implementations

impl FileTreeGenerator

pub fn new<P: AsRef<Path>>( template: FileTreeTemplate, context: TemplateContext, base_dir: P, ) -> Self

Create a new file tree generator

Arguments

• template - The file tree template to generate from
• context - Variable context for template rendering
• base_dir - Base directory where files will be generated

Examples

use ggen_core::templates::generator::FileTreeGenerator;
use ggen_core::templates::{FileTreeTemplate, TemplateContext};
use ggen_core::templates::format::TemplateFormat;
use std::path::Path;

let format = TemplateFormat::new("my-template");
let template = FileTreeTemplate::new(format);
let context = TemplateContext::new();

let generator = FileTreeGenerator::new(template, context, Path::new("output"));

pub fn generate(&mut self) -> Result<GenerationResult>

Generate the file tree from the template

This method:

1. Validates that all required variables are provided
2. Applies default values for optional variables
3. Processes each node in the template tree
4. Creates directories and files with rendered content

Errors

Returns an error if:

• Required variables are missing
• Template rendering fails
• File system operations fail

Examples

use ggen_core::templates::generator::FileTreeGenerator;
use ggen_core::templates::{FileTreeTemplate, TemplateContext};
use ggen_core::templates::format::{TemplateFormat, FileTreeNode};
use std::path::Path;

let mut format = TemplateFormat::new("my-template");
format.add_node(FileTreeNode::directory("src"));
let template = FileTreeTemplate::new(format);
let context = TemplateContext::new();

let mut generator = FileTreeGenerator::new(template, context, Path::new("output"));
let result = generator.generate()?;
println!("Generated {} directories", result.directories().len());
