aEnvVarName

)

Get an environment variable as a specific type, if set correctly.

Parameters

aEnvVarName

the name of the environment variable

Returns

an std::optional containing the value, if set and parseable, otherwise empty.

GetEnvVar() [2/3]

template<>

std::optional< wxString > ENV_VAR::GetEnvVar

(

const wxString &

aEnvVarName

)

Parameters

aEnvVarName

the name of the environment variable

Returns

an std::optional containing the value, if set, otherwise empty.

Definition at line 157 of file env_vars.cpp.

GetEnvVar() [3/3]

template<>

KICOMMON_API std::optional< double > ENV_VAR::GetEnvVar

(

const wxString &

aEnvVarName

)

Get a double from an environment variable, if set.

Parameters

aEnvVarName

the name of the environment variable

Returns

an std::optional containing the value, if set and parseable as a double, otherwise empty.

wxString ENV_VAR::GetVersionedEnvVarName

(

const wxString &

aBaseName

)

Constructs a versioned environment variable based on this KiCad major version.

Parameters

aBaseName

is the suffix, like TEMPLATE_DIR

GetVersionedEnvVarValue()

std::optional< wxString > ENV_VAR::GetVersionedEnvVarValue	(	const std::map< wxString, ENV_VAR_ITEM > &	aMap,
		const wxString &	aBaseName
	)

Attempts to retrieve the value of a versioned environment variable, such as KICAD8_TEMPLATE_DIR.

If this value exists in the map, it will be returned. If not, the map will be searched for keys matching KICAD*_<aBaseName>, and the first match's value will be returned. If there are no matches, std::nullopt will be returned.

Parameters

aMap	is an ENV_VAR_MAP (

environment.h)

Parameters

aBaseName

is the suffix for the environment variable (

IsEnvVarImmutable()

bool ENV_VAR::IsEnvVarImmutable

(

const wxString &

aEnvVar

)

Determine if an environment variable is "predefined", i.e.

if the name of the variable is special to KiCad, and isn't just a user-specified substitution name.

Parameters

aEnvVar

the variable to check

Returns

true if predefined

LookUpEnvVarHelp()

wxString ENV_VAR::LookUpEnvVarHelp

(

const wxString &

aEnvVar

)

Look up long-form help text for a given environment variable.

This is intended for use in more verbose help resources (as opposed to tooltip text)

Parameters

aEnvVar

The variable to look up

Returns

A string with help for that variable. Empty if no help available for this variable.
