Why buy a commercial parser? In some cases, open-source parsers are available, so why consider buying a commercial parser?
Depending on your situation, you may need a parser that has been thoroughly tested and which is documented, and has someone to call in case you encounter any problems.
We create and distribute a commercial off-the-shelf CL parser.
You may want to buy a commercial parser to have a parser ready for the integration, without any technical complexity and easy to integrate. A ready-to-go CL parser.
Three reasons to buy:
CL is a language that has been used extensively for decades.
Nowadays, billions of lines composing extremely valuable software are defined in CL.
You may want to perform several operations on your CL code, which our CL parser might help you with. Let’s discover them:
How to use a parser to build these applications?
We offer the parser in two different formats, allowing you to choose the best approach for your needs:
Service: Access the parser via a cloud-based API.
Library: Integrate it directly into your applications using Java, Python, C#, JavaScript, or Kotlin. This would work without any connection to our API, if not for validating a key (i.e., no code would be shared with our servers).
Once you acquire the parser, we will provide comprehensive documentation to facilitate onboarding.
An introductory meeting will be held to guide you through the setup and integration.
We also offer advanced training, coaching, and support for those needing additional expertise to help implement more sophisticated language engineering solutions.

What does it matter in a parser?

We have built tens of parsers for our clients, written books and created video courses, written hundreds of articles, and given presentations on multiple continents. We have learned some things that are important in a parser to support what our clients want to build with them.
Our parsers provide an Abstract Syntax Tree (AST), not a Parse Tree. This may sound like some academic term just thrown out to appear smart. It is not. The difference is that the output of our parsers is more high-level and easier to work with, and we think this could also be relevant to you.
We provide AST libraries to process the output of our parsers. They permit you to work with the tree more easily to accomplish your goals. We know that as we have built interpreters, editors, compilers, transpilers, and other tools using those libraries, we built them as tools we needed to use in our work.
Error recovery: our parsers can deal with errors in code and recover them to build an AST. This is important for applications that need to process also incorrect code. This is always the case for editors, for example, as the user is constantly writing code, and until they are finished, the code is typically incorrect.

Technical specifications, legal & license details

The CL parser extracts structured models from code, producing an Abstract Syntax Tree (AST). The Code Generation module, available as an optional extension, performs the reverse operation: It converts an AST back into PL/SQL code, allowing structured modifications and generation of new code.
This module is useful in several cases:
1. Generating new PL/SQL code from scratch.
2. Modifying existing PL/SQL code, making it particularly useful for automated refactoring.
By combining the parser and the Code Generation module, you can:
1. Analyze PL/SQL code to detect specific patterns or function calls that are obsolete or incorrect.
2. Modify the AST to introduce structured changes.
3. Regenerate the updated PL/SQL code, ensuring correctness and consistency.
This approach enables automated refactoring, enforcing coding policies, or even generating entirely new PL/SQL files based on predefined AST structures.
We provide a commercial license. You will get access to documentation about the AST and best practices for using the parser. You can choose a Standard, Distribution, or Service License. You will also get our support included with it.

Strumenta Playground
Strumenta Playground is where you can evaluate the parser we build online. You can choose among several open-source examples source files and look at the output of the parser for that file – an AST (Abstract Syntax Tree) representing the logical structure of the input file (and not just the grammatical decomposition of the source into keywords, identifiers, punctuation, and other elements).

Frequently Asked Questions
If I need more information?
When you book a meeting, we will provide several resources regarding our methodology, articles, webinars, and tutorials. If you want to learn more, don’t hesitate to book a meeting with our experts.
Anything else you could help me with?
We are specialists in Language Engineering and can offer all these supporting services to ensure you reach your goals. Typically, our clients buy a transpiler to use as part of larger systems. Sometimes, they have all the internal skills they need to integrate. Still, they often ask us for training courses, support with the architectural design, or the implementation of the entire system for them.
Where can I find references and testimonials of other clients?
You can have a look at our session “Testimonials” to read some customer’s experiences and opinions. You can also find some interviews in the section “Articles“: Interview with Rob Wunderlich or Interview with Campbell Pride.
