not setting a Value
for StringSliceFlag
solves the issue somehow. fancy_name --groups="asdf,foo" --groups="qwertz"
then returns the expected content which is [asdf,foo qwertz]
from cli.
I already tried to set app.SliceFlagSeparator = ";" but this has no effect
I guess that is a bug
or a specific flag
I don't see a real usage fof setting separator per flag but having aSeparator string
on theStringSliceFlag
could solve it
from cli.
Can you try WithSeparatorSpec on the string slice flag ?
from cli.
could you give me a code hint for WithSeparatorSpec
on a StringSliceFlag
? May I do something wrong as Go newbie, because of unknown field 'WithSeparatorSpec' in struct literal of type cli.StringSliceFlag
from cli.
https://github.com/urfave/cli/blob/v2-maint/flag_string_slice.go#L181
Are you using the latest v2 release ?
from cli.
yes I do, v2.27.0
I still believe this is a syntax thing on my side
func GetCliFlags() []cli.Flag {
return []cli.Flag{
&cli.StringSliceFlag{
Name: "groups",
Value: cli.NewStringSlice("this,that,other", "foo"),
Usage: "Groups, can be given multiple times",
WithSeparatorSpec: cli.separatorSpec{sep: ";"},
}
}
from cli.
Ah no you need to do
func GetCliFlags() []cli.Flag {
ssflag := &cli.StringSliceFlag{
Name: "groups",
Value: cli.NewStringSlice("this,that,other", "foo"),
Usage: "Groups, can be given multiple times",
}
ssflag.WithSeparatorSpec(cli.separatorSpec{sep: ";"})
return []cli.Flag{
ssflag,
}
}
from cli.
Thanks for the hint, but it does not work as separatorSpec
is not exported (function starting with lower case). In the yet unreleased v3 this is even no longer available
./first.go:90:34: separatorSpec not exported by package cli
./first.go:90:48: unknown field 'sep' in struct literal of type cli.separatorSpec
I'll stay with v2, keep the setting globally and use no default value
from cli.
