Functions ¶
func AtExit ¶
func AtExit(fn func())
AtExit registers the function fn to be called on program termination. The functions will be called in reverse order they were registered.
func Constrain32 ¶
Constrain32 limits the given 32-bit integer with the upper and lower bounds
func Exit ¶
func Exit(code int)
Exit executes any functions registered with AtExit() then exits the program with os.Exit(code).
NOTE: It must be used instead of os.Exit() since calling os.Exit() terminates the program before any of the AtExit functions can run.
func KillCommand ¶
KillCommand kills the process for the given command
func RepeatToFill ¶
RepeatToFill repeats the given string to fill the given width
func RunAtExitFuncs ¶
func RunAtExitFuncs()
RunAtExitFuncs runs any functions registered with AtExit().
func RunesWidth ¶
RunesWidth returns runes width
func SetNonblock ¶
SetNonblock executes syscall.SetNonblock on file descriptor
func StringWidth ¶
StringWidth returns string width where each CR/LF character takes 1 column
func ToKebabCase ¶
ToKebabCase converts the given CamelCase string to kebab-case
Types ¶
type AtomicBool ¶
type AtomicBool struct {
// contains filtered or unexported fields
}
AtomicBool is a boxed-class that provides synchronized access to the underlying boolean value
func NewAtomicBool ¶
func NewAtomicBool(initialState bool) *AtomicBool
NewAtomicBool returns a new AtomicBool
func (*AtomicBool) Get ¶
func (a *AtomicBool) Get() bool
Get returns the current boolean value synchronously
func (*AtomicBool) Set ¶
func (a *AtomicBool) Set(newState bool) bool
Set updates the boolean value synchronously
type Chars ¶
type Chars struct {
// XXX Piggybacking item index here is a horrible idea. But I'm trying to
// minimize the memory footprint by not wasting padded spaces.
Index int32
// contains filtered or unexported fields
}
func RunesToChars ¶
func (*Chars) LeadingWhitespaces ¶
func (*Chars) TrailingWhitespaces ¶
func (*Chars) TrimLength ¶
TrimLength returns the length after trimming leading and trailing whitespaces
func (*Chars) TrimTrailingWhitespaces ¶
func (chars *Chars) TrimTrailingWhitespaces()
type EventBox ¶
type EventBox struct {
// contains filtered or unexported fields
}
EventBox is used for coordinating events
type Events ¶
type Events map[EventType]interface{}
Events is a type that associates EventType to any data
type Executor ¶
type Executor struct {
// contains filtered or unexported fields
}
func NewExecutor ¶
func (*Executor) ExecCommand ¶
ExecCommand executes the given command with $SHELL
