Explore the power of Haskell for text manipulation and enhance your productivity as you automate and optimize your text processing tasks.

Exploring the Process

Step 1: Define a Type for Placeholders and Values

In Haskell, we start by defining a type TemplateValue, which is essentially a map that associates placeholders with their corresponding values. This abstraction allows for flexible and dynamic template processing, making it a powerful tool in your programming toolkit. We use Data.Map for this purpose.

```haskell importData.Map (Map) import qualified Data.Map as Map importData.Text (Text) import qualified Data.Text as T ```

Step 2: Replace Placeholders in the Template

Here, we create a function replacePlaceholders that takes a TemplateValue and a Text template as input and returns the template with placeholders replaced by their corresponding values. This transformation is crucial for automating repetitive tasks and ensuring consistency in your output.

```haskell -- Define a function to replace placeholders replacePlaceholders :: TemplateValue -> Text -> Text replacePlaceholders values template = ... ```

Step 3: Read the Template from a File

We implement a function readTemplateFile to read the template content from a file specified by its file path. This approach allows you to easily work with templates stored in external files, enhancing code organization and reusability.

```haskell -- Define a function to read the template from a file readTemplateFile :: FilePath -> IO Text readTemplateFilefilePath = ... ```

Step 4: Write the Final Text to a File

Similarly, we create a function writeFinalFile to write the final text, after replacing placeholders, to an output file. This step is vital for saving the processed content and making it readily available for your applications or further processing.

```haskell -- Define a function to write the final text to a file writeFinalFile :: FilePath -> Text -> IO () writeFinalFilefilePath content = ... ```

Step 5: Putting It All Together

Finally, in the main function, we put everything together. We read the template, define values for placeholders, replace the placeholders with values, write the final text to an output file, and print a message to indicate that the template processing is complete. This comprehensive approach simplifies the entire process and ensures that your text conversion tasks are seamless and efficient.

```haskell main :: IO () main = do -- Load the template template<- readTemplateFile "template.txt" -- Define values for placeholders let values = Map.fromList [ ("{name}", "John Doe") , ("{age}", "30") , ("{city}", "Example City") ] -- Replace placeholders with values letfinalText = replacePlaceholders values template -- Write the final text to a file writeFinalFile "output.txt" finalText putStrLn "Template processing complete!" ```
