Struct BridgeOutput

pub struct BridgeOutput {
    pub package_base: HashMap<Keyword, Value>,
    pub packages: HashMap<RawPackageName, HashMap<Keyword, ClearableValue>>,
    pub functions: Vec<RawPackageName>,
}

Represents the raw parsed, but not yet typed output of the alpm-pkgbuild-bridge script.

Fields

package_base: HashMap<Keyword, Value>

The map of all assigned keywords in the pkgbase section of the bridge output.

packages: HashMap<RawPackageName, HashMap<Keyword, ClearableValue>>

The map of all assigned keywords in the package section of the bridge output. The keywords are grouped by package name.

functions: Vec<RawPackageName>

The list of all package function names that are declared in the bridge output.

Implementations

impl BridgeOutput

pub fn from_file(pkgbuild_path: &Path) -> Result<Self, Error>

Creates a BridgeOutput from a PKGBUILD at a given path, by calling the alpm-pkgbuild-bridge script.

pub fn from_script_output(input: &str) -> Result<Self, Error>

Creates a BridgeOutput from some alpm-pkgbuild-bridge script output.

This function is mostly exposed for testing, consider using Self::from_file.

fn parser(input: &mut &str) -> ModalResult<Self>

Parse some given [alpm-pkgbuild-bridge] script output into Self.

Use Self::from_script_output for convenient error handling. Recognizes a BridgeOutput in the output of the alpm-pkgbuild-bridge script.

Errors

Returns an error if no BridgeOutput can be found in input.

fn package_base(input: &mut &str) -> ModalResult<HashMap<Keyword, Value>>

Recognizes a map of Keyword-Value pairs in a string slice.

Backtracks as soon as the next section is hit.

Errors

Returns an error if there is not at least one Keyword-Value pair in input.

fn package_base_line(input: &mut &str) -> ModalResult<(Keyword, Value)>

Recognizes a Keyword-Value pair in a string slice.

Backtracks as soon any other line prefix than VAR GLOBAL is encountered.

Errors

Returns an error if no Keyword-Value pair can be found in input.

fn packages( input: &mut &str, ) -> ModalResult<HashMap<RawPackageName, HashMap<Keyword, ClearableValue>>>

Recognizes an entire section of package variable declarations.

Delegates to BridgeOutput::package_line to recognize singular tuples of RawPackageName, Keyword and ClearableValue per line and combines the data in a HashMap.

Backtracks as soon as the next section is hit.

Errors

Returns an error if BridgeOutput::package_line does not find at least one line in input.

fn package_line( input: &mut &str, ) -> ModalResult<(RawPackageName, Keyword, ClearableValue)>

Recognizes a tuple of RawPackageName, Keyword and ClearableValue in a string slice.

The tuple represents a single package variable line. Backtracks as soon any other line prefix than FUNCTION is encountered.

Errors

Returns an error if one of the components (RawPackageName, Keyword and ClearableValue) is not found in input.

fn functions(input: &mut &str) -> ModalResult<Vec<RawPackageName>>

Recognizes a list of RawPackageNames in a string slice.

Delegates to BridgeOutput::function_line to recognize each singular RawPackageName. This parser may return an empty array, which is the case for alpm-meta-packages without a package function.

Errors

Returns an error if BridgeOutput::function_line fails.

fn function_line(input: &mut &str) -> ModalResult<RawPackageName>

Recognizes a RawPackageName in a string slice.

Errors

Returns an error if no RawPackageName can be found in input.
