type BashishParser ¶

type BashishParser struct {
	// contains filtered or unexported fields
}

BashishParser is a parser for the bashish language. Bashish is a language that is a very simple subset of bash. It is basically shell commands plus the ability to do things like pipe the output of one command to another.

func NewBashishParser() (*BashishParser, error)

func (p *BashishParser) Parse(doc string) ([]Instruction, error)

type Executor ¶

type Executor struct {
	v1alpha1.UnimplementedExecuteServiceServer
	// contains filtered or unexported fields
}

Executor is responsible for executing the commands

func NewExecutor() (*Executor, error)

func (e *Executor) Execute(ctx context.Context, req *v1alpha1.ExecuteRequest) (*v1alpha1.ExecuteResponse, error)

type Instruction ¶

type Instruction struct {
	Command *cmd.Cmd

	// Piped should be set to true if the output of this command should be piped to the next instruction.
	Piped bool
}

Instruction represents one instruction in the bashish language. This is typically a command that should be executed. In addition it contains information about how that command should be executed; e.g. if the output of this command should be piped to the next command.

type Token ¶

type Token struct {
	TokenType TokenType
	Lexeme    string
	Match     *machines.Match
}

func NewToken(tokenType TokenType, m *machines.Match) *Token

type TokenType ¶

type TokenType string

const (
	PipeToken       TokenType = "PIPE"
	QuoteToken      TokenType = "QUOTE"
	UnmatchedToken  TokenType = "UNMATCHED"
	TextToken       TokenType = "TEXT"
	WhiteSpaceToken TokenType = "WHITESPACE"
