+# Labs 06: Compiler extension project
+
+You have now written a compiler for Amy, a simple functional language.
+The final lab project is to design and implement a new functionality of
+your own choice on top of the compiler you built so far. In preparation
+for this, you should aim to learn about the problem domain by searching
+the appropriate literature. The project includes:
+
+-   designing and implementing the new functionality
+-   documenting the results in a written report document
+
+This project has several deadlines, detailed below. Please note that the
+first of them (choosing the topic) is already coming up on this Thursday!
+Use the sessions on Wednesday and Thursday morning to discuss your own
+ideas or choices.
+
+## Selecting a Project Topic
+
+**Deadline: Thursday December 1st**
+
+In the following document, we list several project ideas, but you should
+also feel free to submit your own. All groups will rank the
+projects in order of preference, and we will then do our best to assign
+the preferred projects to as many groups as possible. Because not all
+projects are equally difficult, we annotated each of them with the
+expected workload. The suggested projects cover a wide range of
+complexity, and we will evaluate your submissions with that complexity
+in mind. For instance, for a project marked with `(1)` (relatively low
+complexity) we will be expecting a polished, well-tested and
+well-documented extension, whereas projects on the other end (`(3)`) may
+be more prototypical. For all submissions, however, we require that you
+deliver code that compiles and a set of example input files that
+demonstrate the new functionality.
+
+[Project ideas](material/extensions.pdf)
+
+To announce your preferences, [please fill out this form on Moodle before the deadline](https://moodle.epfl.ch/mod/questionnaire/view.php?id=1231114). You\'ll have to
+provide **the numbers corresponding to the top exactly 5** projects you would like to
+work on, in order of descending preference. We will do our best to
+assign you the project you are most interested in.
+
+## Project Orientation
+
+We will try to inform you about the project assignment during the usual Wednesday and Thursday sessions. We ask you to be **proactive** and validate with the assistants your understanding of the project goals and the expectations of the end product. Think about the following questions and feel free to ask the assistants about them during the exercise sessions:
+
+-   What are the features you will add to the compiler/language?
+-   What would be some (short) programs highlighting the use of these features?
+-   What changes might be required in each compiler phase and/or what new phases would you add? (Very roughly)
+
+
+## Project Presentation
+
+You will present your idea during the last two weeks of the semester (Dec 14/15/19/21/22). We'll announce the concrete
+schedule of presentations at a later point. [Instructions on what and how to present your project can be found here.](material/presentation.md)
+
+## Project Implementation and Report
+
+You will develop your project on top of your implementation of Amy. Please push all development on a new branch `clplab6`, ideally building on top of the codegen lab. We will refer to this branch in case of problems with your submission.
+
+Deadline: **TBD**.
+
+Submission: content of the clplab6 branch.
+
+Final form of your submission should contain:
+
+-   Your implementation, which must, to be graded at all, compile and be able to run non-trivial examples.
+-   A subdirectory `extension-examples/` which includes **at least 5 examples** that demonstrate your compiler extension in action.
+-   A subdirectory `report/` which includes a PDF summarizing your extension. 
+-   A subdirectory `slides/` which includes the PDF of the project presentation.
+-   A README file indicating how we should run and test the implemented functionality, with examples.
+
+
+**If you did not manage to complete your planned features, or they are
+partially implemented, make this clear in your report!**
+
+You are encouraged to use the following (LaTeX) template for your
+report:
+
+-   [LaTeX sources](material/report-template.tar.gz)
+
+A PDF version of the template with the required section is available
+here:
+
+-   [PDF Example](material/report-template.pdf)
+
+Although you are not required to use the above template, your report
+must contain at least the sections described in it with the appropriate
+information. Note that writing this report will take some time, and you
+should not do it in the last minute. The final report is an important
+part of the compiler project. If you have questions about the template
+or the contents of the report, make sure you ask them early.
+
+A common question is \"how long should the report be?\". There\'s no
+definitive answer to that. Considering that the report will contain code
+examples and a technical description of your implementation, it would be
+surprising if it were shorter than 3 pages. Please try to stay within 6
+pages. A concise, but well-written report is preferable to a long, but
+poorly-written one.

+## Compiler Extension Presentation Instructions
+
+Presentations will take place in the weeks 13-14. 
+
+**The presentation should be 9 minutes long.**
+
+**Q&A session of 5 minutes** will follow right after the
+presentation. 
+
+Shortly after, you will receive feedback from us regarding the content
+of your presentation, as well as some general feedback on the form.
+
+### Presentation content
+
+Your presentation should summarize your project. In particular, we\'d
+expect to see
+
+-   a basic overview of the features you added to the compiler/language
+-   some (short) programs highlighting the use of these features, with a
+    description of how your extended compiler behaves on them
+-   possibly some theoretical background you had to learn about to
+    implement the extension
+-   an overview of the changes you made to each compiler phase and/or
+    which phases you added
+
+### Presentation style
+
+Here are some useful resources on how to prepare and give talks:
+
+-   [How To Speak by Patrick
+    Winston](https://www.youtube.com/watch?v=Unzc731iCUY)
+-   [How to give a great research talk by Simon Peyton
+    Jones](https://www.microsoft.com/en-us/research/academic-program/give-great-research-talk/)
+
+Please do not use Viktor\'s videos as a model for the presentation, but
+instead incorporate as many points of the talk of [Patrick
+Winston](https://en.wikipedia.org/wiki/Patrick_Winston) as you believe
+apply to your presentation. It is an amazing and entertaining talk,
+despite (or because) it is meta-circular: he does as he says. Note:
+breaking physical objects or referring to supernatural beings in your
+video is not required. Use your own judgment and strike a balance in
+being comfortable with what and how you are saying things and trying out
+these pieces of advice.
