# Code Skeleton for Lab 3 and Lab 4
This folder contains the code skeleton that you will be working on during Lab 3 and Lab 4.
## Lab 3
For Lab 3 two files are of interest, `parser.y` and `scanner.l`.
To start, begin by integrating what you did in lab 1 to the `scanner.l` file.
Here it is important that you are careful, and that you do not simply copy paste.
Look at the structure of `scanner.l` and enter your rules s.t you do not remove any includes present in that file.
### Testing Lab 3.
There is a number of test files in the `test` directory that you may use to check if your parser works as expected.
We also provide traces that you can use to compare the output of your solution to some expected output.
To do this you can exceute the following sequence of commands.
To check if you get about the same result for expressions you can run:
```bash
./compiler ./test/expression_test.prog > my_output.txt
diff -y my_output.txt ../traces/trace_expression_test.txt
```
The same procedure can be done for the more advanced test, that is `traces/trace-lab3.txt`
```
./compiler ./test/test > my_output.txt
diff -y my_output.txt ../traces/trace-lab3.txt
```
## Lab 4
In lab 4 you will work in file `codegen.cc` search for `/* --- Your code here --- */`'
to see where you need to introduce your changes.
### Testing Lab 4
In order to test Lab 4, there exists a test script.
For more details see the README in the test folder.
## Other notes
For more exhaustive documentation see [The Lab Skeleton Documentation](https://www.ida.liu.se/~TDDD55/laboratories/instructions/_static/skeleton.pdf)
