Overview ¶
Package inputrc parses readline inputrc files.
Example ¶
package main
import (
"os/user"
"github.com/alexj212/readline/inputrc"
)
func main() {
u, err := user.Current()
if err != nil {
panic(err)
}
cfg := inputrc.NewDefaultConfig()
if err := inputrc.UserDefault(u, cfg, inputrc.WithApp("bash")); err != nil {
panic(err)
}
}
Output:

Functions ¶
func DefaultBinds ¶
DefaultBinds are the default readline bind keymaps.
see: INPUTRC=/dev/null bash -c 'bind -pm <keymap>'
func DefaultVars ¶
func DefaultVars() map[string]interface{}
DefaultVars are the default readline vars.
see: INPUTRC=/dev/null bash -c 'bind -v'
func Parse ¶
Parse parses inputrc data from r.
Example ¶
package main
import (
"fmt"
"strings"
"github.com/alexj212/readline/inputrc"
)
func main() {
const example = `
set editing-mode vi
$if Usql
set keymap vi-insert
"\r": a-usql-action
"\d": 'echo test\n'
$endif
`
cfg := inputrc.NewDefaultConfig()
if err := inputrc.Parse(strings.NewReader(example), cfg, inputrc.WithApp("usql")); err != nil {
panic(err)
}
fmt.Println("editing mode:", cfg.GetString("editing-mode"))
fmt.Println("vi-insert:")
fmt.Printf(" %s: %s\n", inputrc.Escape(string(inputrc.Return)), cfg.Binds["vi-insert"][string(inputrc.Return)].Action)
fmt.Printf(" %s: '%s'\n", inputrc.Escape(string(inputrc.Delete)), inputrc.EscapeMacro(cfg.Binds["vi-insert"][string(inputrc.Delete)].Action))
}
Output: editing mode: vi vi-insert: \C-M: a-usql-action \C-?: 'echo test\n'
func ParseBytes ¶
ParseBytes parses inputrc data from buf.
Types ¶
type Config ¶
type Config struct {
ReadFileFunc func(string) ([]byte, error)
Vars map[string]interface{}
Binds map[string]map[string]Bind
Funcs map[string]func(string, string) error
}
Config is a inputrc config handler.
func NewDefaultConfig ¶
func NewDefaultConfig(opts ...ConfigOption) *Config
NewDefaultConfig creates a new inputrc config with default values.
type ConfigOption ¶
type ConfigOption func(*Config)
ConfigOption is a inputrc config handler option.
func WithConfigReadFileFunc ¶
func WithConfigReadFileFunc(readFileFunc func(string) ([]byte, error)) ConfigOption
WithConfigReadFileFunc is a inputrc config option to set the func used for ReadFile operations.
type Error ¶
type Error string
Error is a error.
const ( // ErrBindMissingClosingQuote is the bind missing closing quote error. ErrBindMissingClosingQuote Error = `bind missing closing quote` // ErrMissingColon is the missing : error. ErrMissingColon Error = "missing :" // ErrMacroMissingClosingQuote is the macro missing closing quote error. ErrMacroMissingClosingQuote Error = `macro missing closing quote` // ErrInvalidKeymap is the invalid keymap error. ErrInvalidKeymap Error = "invalid keymap" // ErrInvalidEditingMode is the invalid editing mode error. ErrInvalidEditingMode Error = "invalid editing mode" // ErrElseWithoutMatchingIf is the $else without matching $if error. ErrElseWithoutMatchingIf Error = "$else without matching $if" // ErrEndifWithoutMatchingIf is the $endif without matching $if error. ErrEndifWithoutMatchingIf Error = "$endif without matching $if" // ErrUnknownModifier is the unknown modifier error. ErrUnknownModifier Error = "unknown modifier" )
Errors.
type Handler ¶
type Handler interface {
// ReadFile reads a file.
ReadFile(name string) ([]byte, error)
// Do handles $constructs.
Do(typ string, param string) error
// Set sets the value.
Set(name string, value interface{}) error
// Get gets the value.
Get(name string) interface{}
// Bind binds a key sequence to an action for the current keymap.
Bind(keymap, sequence, action string, macro bool) error
}
Handler is the handler interface.
type Option ¶
type Option func(*Parser)
Option is a parser option.
func WithHaltOnErr ¶
WithHaltOnErr is a parser option to set halt on every encountered error.
func WithStrict ¶
WithStrict is a parser option to set strict keymap parsing.
type ParseError ¶
ParseError is a parse error.
func (*ParseError) Error ¶
func (err *ParseError) Error() string
Error satisfies the error interface.
func (*ParseError) Unwrap ¶
func (err *ParseError) Unwrap() error
Unwrap satisfies the errors.Unwrap call.
