Overview ¶
Package executor provides command execution abstractions for the gsh REPL. It supports both bash command execution and gsh script execution, managing environment variables and working directory state.

Types ¶
type ExecMiddleware ¶
type ExecMiddleware = func(next shinterp.ExecHandlerFunc) shinterp.ExecHandlerFunc
ExecMiddleware is a function that wraps an ExecHandlerFunc to provide additional functionality (e.g., command interception, logging).
type REPLExecutor ¶
type REPLExecutor struct {
// contains filtered or unexported fields
}
REPLExecutor handles command execution for the REPL using the interpreter's shared sh runner for bash execution and gsh script execution.
func NewREPLExecutor ¶
func NewREPLExecutor(interp *interpreter.Interpreter, logger *zap.Logger, execHandlers ...ExecMiddleware) (*REPLExecutor, error)
NewREPLExecutor creates a new REPLExecutor. The interpreter is required and provides the shared sh runner for bash execution. The logger is optional (can be nil). The execHandlers are optional middleware for intercepting command execution (e.g., for history and completion).
func (*REPLExecutor) AliasExists ¶
func (e *REPLExecutor) AliasExists(name string) bool
AliasExists returns true if the given name is currently defined as a shell alias in the underlying mvdan/sh runner.
Note: mvdan/sh keeps aliases in an unexported field, so we use reflection.
func (*REPLExecutor) AliasOrFunctionExists ¶ added in v1.0.1
func (e *REPLExecutor) AliasOrFunctionExists(name string) bool
AliasOrFunctionExists returns true if the given name is defined as either a shell alias or a shell function. This is useful for syntax highlighting to recognize user-defined commands from config files like .gshenv and .gsh_profile.
func (*REPLExecutor) Close ¶
func (e *REPLExecutor) Close() error
Close cleans up any resources held by the executor.
func (*REPLExecutor) ExecuteBash ¶
ExecuteBash runs a bash command with output going to stdout/stderr. Returns the exit code and any execution error.
func (*REPLExecutor) ExecuteBashInSubshell ¶
func (e *REPLExecutor) ExecuteBashInSubshell(ctx context.Context, command string) (string, string, int, error)
ExecuteBashInSubshell runs a bash command in a subshell, capturing output. Returns stdout, stderr, exit code, and any execution error.
func (*REPLExecutor) ExecuteGsh ¶
func (e *REPLExecutor) ExecuteGsh(ctx context.Context, script string) error
ExecuteGsh runs a gsh script. Returns any execution error.
func (*REPLExecutor) FunctionExists ¶ added in v1.0.1
func (e *REPLExecutor) FunctionExists(name string) bool
FunctionExists returns true if the given name is currently defined as a shell function in the underlying mvdan/sh runner.
Note: mvdan/sh's Funcs field is exported, but we still use reflection for consistency.
func (*REPLExecutor) GetEnv ¶
func (e *REPLExecutor) GetEnv(name string) string
GetEnv gets an environment variable value from the interpreter's runner.
func (*REPLExecutor) GetPwd ¶
func (e *REPLExecutor) GetPwd() string
GetPwd returns the current working directory from the interpreter's runner.
func (*REPLExecutor) Interpreter ¶
func (e *REPLExecutor) Interpreter() *interpreter.Interpreter
Interpreter returns the underlying gsh interpreter. This is useful for advanced use cases that need direct access.
func (*REPLExecutor) RunBashScriptFromReader ¶
func (e *REPLExecutor) RunBashScriptFromReader(ctx context.Context, reader io.Reader, name string) error
RunBashScriptFromReader runs a bash script from an io.Reader.
func (*REPLExecutor) Runner ¶
func (e *REPLExecutor) Runner() *shinterp.Runner
Runner returns the underlying mvdan/sh runner from the interpreter. This is useful for advanced use cases that need direct access.
func (*REPLExecutor) SetEnv ¶
func (e *REPLExecutor) SetEnv(name, value string)
SetEnv sets an environment variable in the interpreter's runner.
