Complete the symbol table data structure so that it can be used while parsing.

Write lexer tests

Change grammar rules to use left recursion, so that less stack space is used.

Write up a document outlining the design of the compiler. Include at least the following:

Component separation
Interface between components
Testing
Considerations for expansion
Potential issues and mitigating actions

Create a folder structure that is easy to navigate and find pertinent files.

Implement actions for programs (ISO 7185 Section 6.10).

Replaces #15

Implement actions for handling input and output function calls (ISO 7185 Section 6.9).

Replaces #15

Implement actions involving variable declarations (ISO 7185 Section 6.5).

Replaces #15

Write all #defines, static lookup tables, headers, etc. for the lexer.

Copy the grammar described in the standard to parser.y.
Ignore shift/reduce and reduce/reduce errors for this issue. (see #13 )

Implement actions involving expressions (ISO 7185 Section 6.7).

Replaces #15

Implement actions involving statements (ISO 7185 Section 6.8).

Replaces #15

Running debugtokentree() on blocks only show certain declaration/statement parts, and of those, not all the declarations are present. Fix how tokens are passed through parser reductions to show the complete declaration/statement parts.

Write code to take each lexeme and wrap it into a token.

Find the Pascal language spec and AVR ISA spec, place them in the repo.

Implement actions involving constants (ISO 7185 Section 6.3).

Replaces #15

Implement actions involving types (ISO 7185 Section 6.4).

Replaces #15

Write a regular language for Pascal in the flex format.

Change tests to use shell script instead of python, since the target check in the Makefile can only use certain programs as described below:
https://www.gnu.org/prep/standards/html_node/Utilities-in-Makefiles.html#Utilities-in-Makefiles

Create a makefile with targets:
all
check
clean
lexer
parser
codegen

Implement actions involving blocks and scopes (ISO 7185 Section 6.2). Add code to manipulate symbol table level appropriately.

Replaces #15

Implement actions involving procedure/function declarations (ISO 7185 Section 6.6).

Replaces #15

Fix shift/reduce and reduce/reduce errors in grammar in parser.y.
Depends on #12 to be complete first.

Add code to perform token manipulation during reduction operations.
