Struct VariableDefinition 

pub struct VariableDefinition(/* private fields */);

An AST node for $ast

Implementations

impl VariableDefinition

pub fn name(&self) -> Option<String>

Get the name of the variable definition

pub fn raw_value(&self) -> Option<String>

Get the raw value of the variable definition

pub fn remove(&mut self)

Remove this variable definition from its parent makefile

This will also remove any preceding comments and up to 1 empty line before the variable.

Example

use makefile_lossless::Makefile;
let mut makefile: Makefile = "VAR = value\n".parse().unwrap();
let mut var = makefile.variable_definitions().next().unwrap();
var.remove();
assert_eq!(makefile.variable_definitions().count(), 0);

pub fn set_value(&mut self, new_value: &str)

Update the value of this variable definition while preserving the rest (export prefix, operator, whitespace, etc.)

Example

use makefile_lossless::Makefile;
let mut makefile: Makefile = "export VAR := old_value\n".parse().unwrap();
let mut var = makefile.variable_definitions().next().unwrap();
var.set_value("new_value");
assert_eq!(var.raw_value(), Some("new_value".to_string()));
assert!(makefile.code().contains("export VAR := new_value"));

Trait Implementations

impl AstNode for VariableDefinition

type Language = Lang

fn can_cast(kind: SyntaxKind) -> bool

fn cast(syntax: SyntaxNode<Lang>) -> Option<Self>

fn syntax(&self) -> &SyntaxNode<Lang>

impl Display for VariableDefinition

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for VariableDefinition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for VariableDefinition

fn eq(&self, other: &VariableDefinition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
