Feature/Parser improvements #28

Closed alexdesousa closed 2 years ago

alexdesousa commented 2 years ago

This PR adds several improvements to the parser:

[x] Added new lexer with improved tokens. Now these tokens track:
- lines and columns for each token.
- original and modified contents.
[x] Added new parser with support for both named and unamed queries.
[x] Improved compiler errors. Now they show:
- line and columns where errors occur.
- surrounding lines containing the error.
[x] Added missing tests for the runners.

This changes:

[x] fixes #25
- The new lexer adds support for strings like :=
- The docs now refer to Optional Fragments instead of Optional Parameters.
[x] Partially fixes #27: it does not add support for strings in the macro defqueries/1, but the same functionality is accessible via the module AyeSQL.Compiler.
[x] Fixes #17: by adding the example from the issue into the docs.
