panda3d.core.ExecutionEnvironment¶

from panda3d.core import ExecutionEnvironment

class ExecutionEnvironment¶

Encapsulates access to the environment variables and command-line arguments at the time of execution. This is encapsulated to support accessing these things during static init time, which seems to be risky at best.

Inheritance diagram

__init__(param0: ExecutionEnvironment) → None¶

static hasEnvironmentVariable(var: str) → bool¶: Returns true if the indicated environment variable is defined.

static getEnvironmentVariable(var: str) → str¶: Returns the definition of the indicated environment variable, or the empty string if the variable is undefined.

static setEnvironmentVariable(var: str, value: str) → None¶: Changes the definition of the indicated environment variable.

static shadowEnvironmentVariable(var: str, value: str) → None¶: Changes the apparent definition of the indicated environment variable by masking it within this class with a new value. This does not change the actual environment variable, but future calls to getEnvironmentVariable() will return this new value.

static clearShadow(var: str) → None¶: Removes a value set by a previous call to shadowEnvironmentVariable(), and lets the actual value of the variable show again.

static expandString(str: str) → str¶

Reads the string, looking for environment variable names marked by a $. Expands all such variable names. A repeated dollar sign ($$) is mapped to a single dollar sign.

Returns the expanded string.

static getNumArgs() → size_t¶

Returns the number of command-line arguments available, not counting arg 0, the binary name.

Return type: size_t

static getArg(n: size_t) → str¶: Returns the nth command-line argument. The index n must be in the range [0 .. getNumArgs()). The first parameter, n == 0, is the first actual parameter, not the binary name.

static getBinaryName() → str¶: Returns the name of the binary executable that started this program, if it can be determined.

static getDtoolName() → str¶: Returns the name of the libdtool DLL that is used in this program, if it can be determined.

static setBinaryName(name: str) → None¶: Do not use.

static setDtoolName(name: str) → None¶: Do not use.

static getCwd() → Filename¶

Returns the name of the current working directory.

Return type: Filename

property environment_variables¶

Getter: Returns the definition of the indicated environment variable, or the empty string if the variable is undefined.
Setter: Changes the definition of the indicated environment variable.

Return type: Mapping[string]

property args¶

Returns the nth command-line argument. The index n must be in the range [0 .. getNumArgs()). The first parameter, n == 0, is the first actual parameter, not the binary name.

Return type: Sequence[string]

property binary_name¶

Getter: Returns the name of the binary executable that started this program, if it can be determined.
Setter: Do not use.

Return type: string

property dtool_name¶

Getter: Returns the name of the libdtool DLL that is used in this program, if it can be determined.
Setter: Do not use.

Return type: string

property cwd¶

Returns the name of the current working directory.

Return type: Filename
