Functions ¶
func ParseFileCallback ¶
func ParseFileCallback(fileName string, c Config, callback ParseCallback) error
func ParseStreamCallback ¶
func ParseStreamCallback(reader io.Reader, c Config, callback ParseCallback) error
ParseStreamCallback parses stream and calls callback on node or error
Types ¶
type Config ¶
type Config struct {
// CommentChar contains the character used to indicate that the line is a comment
CommentChar uint8
}
Config contains the parser configuration
func NewDefaultConfig ¶
func NewDefaultConfig() Config
NewDefaultConfig returns the default set of parser configuration
type ErrorBadSyntax ¶
ErrorBadSyntax used when the stream contains bad syntax
func NewErrorBadSyntax ¶
func NewErrorBadSyntax(lineNumber int, line string) *ErrorBadSyntax
NewErrorBadSyntax creates new ErrorBadSyntax error
func (*ErrorBadSyntax) Error ¶
func (e *ErrorBadSyntax) Error() string
Error returns the error message
type ErrorConversion ¶
type ErrorConversion struct {
Text string
LineNumber int
Line string
// contains filtered or unexported fields
}
ErrorConversion raised when the element value cannot be parsed as float
func NewErrorConversion ¶
func NewErrorConversion(err error, text string, lineNumber int, line string) *ErrorConversion
NewErrorConversion creates new ErrorConversion error
func (*ErrorConversion) Error ¶
func (e *ErrorConversion) Error() string
Error returns the error message
type ErrorIO ¶
type ErrorIO struct {
FileName string
// contains filtered or unexported fields
}
ErrorIO raised on IO issue
func NewErrorIO ¶
NewErrorIO creates new IO Error
type ParseCallback ¶
type ParseCallback func(n *shared.ParserNode, err error) (stop bool, cbError error)
ParseCallback is called on node or error event when parsing the stream
type Parser ¶
type Parser struct {
Nodes chan *shared.ParserNode
Errors chan error
Done chan bool
// contains filtered or unexported fields
}
Parser is the parser data structure
func (Parser) ParseStream ¶
ParseStream parses the contents of stream
Example ¶
package main
import (
"fmt"
"strings"
"github.com/aquilax/hranoprovod-cli/v3/parser"
)
func main() {
p := parser.NewParser(parser.NewDefaultConfig())
file := `2011/07/17:
el1: 1.22
ел 2: 4
el/3: 3
2011/07/18:
el1: 1.33
ел 5: 5
el/7: 4
el1: 1.35
`
go p.ParseStream(strings.NewReader(file))
func() {
for {
select {
case node := <-p.Nodes:
fmt.Println(node.Header)
case <-p.Errors:
return
case <-p.Done:
return
}
}
}()
}
Output: 2011/07/17 2011/07/18
