Functions

func AddPrefixedValues

func AddPrefixedValues(addedTo url.Values, toBeAdded url.Values, prefix string)

func AddValues

func AddValues(addedTo url.Values, toBeAdded url.Values)

func DateRangeToCGIArgs

func DateRangeToCGIArgs(s, e time.Time) string

func DateRangeToValues

func DateRangeToValues(s, e time.Time) url.Values

func ExtractAllCGIArgs

func ExtractAllCGIArgs(r *http.Request) url.Values

ExtractAllCGIArgs gets both GET and POST arguments into a single map

func FormValueCheckbox

func FormValueCheckbox(r *http.Request, name string) bool

func FormValueCommaSepStrings

func FormValueCommaSepStrings(r *http.Request, name string) []string

func FormValueCommaSpaceSepStrings

func FormValueCommaSpaceSepStrings(r *http.Request, name string) []string

Separate by comma, or space

func FormValueDateRange

func FormValueDateRange(r *http.Request) (s, e time.Time, err error)

Return values:

s  will be the first second of the first day;
e  will be the last second of the last day;

For ranges of exactly one day, e and s will be in the same day.

Formats:

?date=today
?date=yesterday
?date=day&day=2006/01/02
?date=range&range_from=2006/01/01&range_to=2018/01/01

func FormValueDuration

func FormValueDuration(r *http.Request, name string) time.Duration

As well as the normal syntax, we support "7d", where a day is 24*time.Hour.

func FormValueEpochTime

func FormValueEpochTime(r *http.Request, name string) time.Time

func FormValueFloat64

func FormValueFloat64(w http.ResponseWriter, r *http.Request, name string) float64

func FormValueFloat64EatErrs

func FormValueFloat64EatErrs(r *http.Request, name string) float64

func FormValueFloat64WithDefault

func FormValueFloat64WithDefault(r *http.Request, name string, dflt float64) float64

func FormValueInt64

func FormValueInt64(r *http.Request, name string) int64

func FormValueIntWithDefault

func FormValueIntWithDefault(r *http.Request, name string, dflt int) int

func GetTemplates

func GetTemplates(ctx context.Context) *template.Template

GetFoo: given a context, extracts the object (or panics; should not be optional)

func ParseRecursive

func ParseRecursive(t *template.Template, dir string) *template.Template

ParseRecursive walks the directory structure, loading all the files it finds. Will panic on failure. Follows symlinks.

func URLStringReplacingGETArgs

func URLStringReplacingGETArgs(r *http.Request, vals *url.Values) string

Creates a URL that matches the request, adding the vals as CGI GET parameters

func ValuesIntoTemplateParams

func ValuesIntoTemplateParams(stem string, values url.Values, params map[string]interface{})

ValuesIntoTemplateParams converts a set of url.Values into template parameters, suitable

for initializing HTML form elements

Types

type BaseHandler

type BaseHandler func(http.ResponseWriter, *http.Request)

func WithCtx

func WithCtx(f CtxMaker, ch ContextHandler) BaseHandler

Outermost wrapper; all other wrappers take (and return) contexthandlers

func WithCtxTmpl(f CtxMaker, t *template.Template, ch ContextHandler) BaseHandler

type ContextHandler

type ContextHandler func(context.Context, http.ResponseWriter, *http.Request)

func WithTemplates

func WithTemplates(t *template.Template, ch ContextHandler) ContextHandler

WithFoo: injects relevant object into the context

type CtxMaker

type CtxMaker func(*http.Request) context.Context

type Presenter

type Presenter interface {
	Values() url.Values
	FromFormValues(v url.Values, stem string) error
}
