Utility functions used in the library but also useful for individual use in preprocessing and postprocessing LLM inputs and outputs
Here is a overview of the functions which are exported from the @promptbook/utils package and can be used in your own projects:
Sometimes you need to postprocess the output of the LLM model, every postprocessing function that is available through POSTPROCESS command in promptbook is exported from @promptbook/utils. You can use:
spaceTrimextractAllBlocksFromMarkdown, <- Note: Exported from @promptbook/markdown-utilsextractAllListItemsFromMarkdown <- Note: Exported from @promptbook/markdown-utilsextractBlockextractOneBlockFromMarkdown <- Note: Exported from @promptbook/markdown-utilsprettifyPipelineStringremoveContentCommentsremoveEmojisremoveMarkdownFormatting <- Note: Exported from @promptbook/markdown-utilsremoveQuotestrimCodeBlocktrimEndOfCodeBlockunwrapResultVery often you will use unwrapResult, which is used to extract the result you need from output with some additional information:
import { unwrapResult } from '@promptbook/utils';
unwrapResult('Best greeting for the user is "Hi Pavol!"'); // 'Hi Pavol!'
There is a function replaceParameters which is used to replace the parameters in given template optimized to LLM prompt templates.
import { replaceParameters } from '@promptbook/utils';
replaceParameters('Hello, {name}!', { name: 'world' }); // 'Hello, world!'
And also multiline templates with blockquotes
import { replaceParameters, spaceTrim } from '@promptbook/utils';
replaceParameters(
spaceTrim(`
Hello, {name}!
> {answer}
`),
{
name: 'world',
answer: spaceTrim(`
I'm fine,
thank you!
And you?
`),
},
);
// Hello, world!
//
// > I'm fine,
// > thank you!
// >
// > And you?
Theese functions are usefull to count stats about the input/output in human-like terms not tokens and bytes, you can use
countCharacters, countLines, countPages, countParagraphs, countSentences, countWords
import { countWords } from '@promptbook/utils';
console.log(countWords('Hello, world!')); // 2
Splitting functions are similar to counting but they return the splitted parts of the input/output, you can use
splitIntoCharacters, splitIntoLines, splitIntoPages, splitIntoParagraphs, splitIntoSentences, splitIntoWords
import { splitIntoWords } from '@promptbook/utils';
console.log(splitIntoWords('Hello, world!')); // ['Hello', 'world']
Normalization functions are used to put the string into a normalized form, you can use
kebab-case
PascalCase
SCREAMING_CASE
snake_case
kebab-case
import { normalizeTo } from '@promptbook/utils';
console.log(normalizeTo['kebab-case']('Hello, world!')); // 'hello-world'
capitalize, decapitalize, removeDiacritics,...POSTPROCESS command in promptbookSee also the documentation for all the functions in the @promptbook/utils package, every function is documented by jsdoc, typed by typescript and tested by jest.

Rest of the documentation is common for entire promptbook ecosystem:
If you have a simple, single prompt for ChatGPT, GPT-4, Anthropic Claude, Google Gemini, Llama 2, or whatever, it doesn't matter how you integrate it. Whether it's calling a REST API directly, using the SDK, hardcoding the prompt into the source code, or importing a text file, the process remains the same.
But often you will struggle with the limitations of LLMs, such as hallucinations, off-topic responses, poor quality output, language drift, word repetition repetition repetition repetition or misuse, lack of context, or just plain w๐๐ขrd responses. When this happens, you generally have three options:
In all of these situations, but especially in 3., the Promptbook library can make your life easier.
.ptbk.md that can be used to describe your prompt business logic without having to write code or deal with the technicalities of LLMs.:) can't avoid the problems. In this case, the library has built-in anomaly detection and logging to help you find and fix the problems.Prompt book markdown file (or .ptbk.md file) is document that describes a pipeline - a series of prompts that are chained together to form somewhat reciepe for transforming natural language input.

Note: We are using postprocessing functions like unwrapResult that can be used to postprocess the result.
This library is divided into several packages, all are published from single monorepo. You can install all of them at once:
npm i ptbk
Or you can install them separately:

Different levels of abstraction. OpenAI library is for direct use of OpenAI API. This library is for a higher level of abstraction. It define pipelines that are independent of the underlying library, LLM model, or even LLM provider.
Langchain is primarily aimed at ML developers working in Python. This library is for developers working in javascript/typescript and creating applications for end users.
We are considering creating a bridge/converter between these two libraries.
GPTs are chat assistants that can be assigned to specific tasks and materials. But they are still chat assistants. Promptbooks are a way to orchestrate many more predefined tasks to have much tighter control over the process. Promptbooks are not a good technology for creating human-like chatbots, GPTs are not a good technology for creating outputs with specific requirements.
If you use raw SDKs, you just put prompts in the sourcecode, mixed in with typescript, javascript, python or whatever programming language you use.
If you use promptbooks, you can store them in several places, each with its own advantages and disadvantages:
As source code, typically git-committed. In this case you can use the versioning system and the promptbooks will be tightly coupled with the version of the application. You still get the power of promptbooks, as you separate the concerns of the prompt-engineer and the programmer.
As data in a database In this case, promptbooks are like posts / articles on the blog. They can be modified independently of the application. You don't need to redeploy the application to change the promptbooks. You can have multiple versions of promptbooks for each user. You can have a web interface for non-programmers to create and modify promptbooks. But you lose the versioning system and you still have to consider the interface between the promptbooks and the application (= input and output parameters).
In a configuration in environment variables. This is a good way to store promptbooks if you have an application with multiple deployments and you want to have different but simple promptbooks for each deployment and you don't need to change them often.
A single promptbook can be written for several (human) languages at once. However, we recommend that you have separate promptbooks for each language.
In large language models, you will get better results if you have prompts in the same language as the user input.
The best way to manage this is to have suffixed promptbooks like write-website-content.en.ptbk.md and write-website-content.cs.ptbk.md for each supported language.
