# GCode Parser

This crate aims at providing a gcode parser to the rusty printer project (and other if it can fit).

The minimal footprint is achieved with all features disabled and is in the order of **~80B** of

RAM and around **2kB** of Flash memory. The typical set of features

`["parse-trailing-comment", "parse-checksum", "optional-value"]` has a footprint of around **4kB**

of flash memory for around **80B** of RAM.

Finally with all features, the memory footprint reaches around **7kB** in flash and around **170B**

in RAM.

## Features

- `std` : Enabled by default

- `parse-comments` : enables the parser to return `GCode::Comment(String)`; requires an allocator.

- `parse-trailing-comment`: allows line to end with a `; comment`.

- `parse-checksum` : Enables the use of xorsum.

- `parse-parameters` : Enables the use of `#` parameters ; requires an allocator.

  If `string-value` is enabled then parameters may use string index.

  If `optional-value` is enabled then parameters value may be omitted but **NOT** the indices.

- `parse-expressions` : Enables parsing infix expressions ; requires an allocator.

- `optional-value` : Allows to omit in `RealValue` in word and parameter value positions.

  Parameter indices cannot be omitted nor can be literals in expressions.

- `string-value` : Allows `RealValue` to be a string. Any character preceded with `\` will be

  used as is (useful for `"`, `)` or new line).

## Design

### Constraints

- No recursion.

- Reduced RAM footprint

- Reduced ROM footprint
