Functions ¶
func LineNumber ¶
LineNumber prefixes returns s prefixed with a line number for each line, starting from 1. Useful for adding line numbers to source.
Example ¶
package main
import (
"fmt"
"github.com/google/gapid/core/text"
)
func main() {
fmt.Println(text.LineNumber(
`This is some text.
That will have line numbers
added to it.
You may notice that the
line numbers will be of
a fixed width
so that text doesn't move
off to the right once
you get to the 10th line.`))
}
Output: 1: This is some text. 2: That will have line numbers 3: added to it. 4: 5: You may notice that the 6: line numbers will be of 7: a fixed width 8: so that text doesn't move 9: off to the right once 10: you get to the 10th line.
func Quote ¶
Quote takes a slice of strings, and returns a slice where each string has been quoted and escaped to pass down to the command-line.
func SplitArgs ¶
SplitArgs splits and returns the string s separated by non-quoted whitespace. Useful for splitting a string containing multiple command-line parameters.
Example ¶
package main
import (
"fmt"
"github.com/google/gapid/core/text"
)
func main() {
for i, s := range text.SplitArgs(`--cat=meow -dog woof "fish"="\"blub blub\""`) {
fmt.Printf("%v: '%v'\n", i, s)
}
}
Output: 0: '--cat=meow' 1: '-dog' 2: 'woof' 3: 'fish="blub blub"'
Types ¶
type LimitWriter ¶
type LimitWriter struct {
// contains filtered or unexported fields
}
LimitWriter limits the length of string written through it.
func NewLimitWriter ¶
func NewLimitWriter(to io.Writer, limit int, elisionMarker string) *LimitWriter
NewLimitWriter returns an io.Writer that limits the amount of text written through it and optionally adds a marker if it causes the limit to be reached.
func (*LimitWriter) Flush ¶
func (w *LimitWriter) Flush() error
Flush any writes to the underlying stream. It also makes the writer assume the limit has been reached for the purpose of any further writes.
func (*LimitWriter) Write ¶
func (w *LimitWriter) Write(data []byte) (int, error)
Write will write as much of the string as it can to the underlying writer, if he total number of runes written would exceed the limit, the last part of the string is replaced by the elisionMarker. This method may buffer data, you must call Flush for it all to appear in the underlying stream.
