Improve parsing of embedded options in the CLI

[xamir82]

Running the following command:

vips copy image.jpg .csv[separator=,]

Yields this error:

get_token: expected string, saw comma

Apparently the comma is being mistaken as a separator of options; and there doesn't seem to be any way to escape it. I've tried enclosing it in quotes, but that doesn't appear to work:

vips copy image.jpg .csv[separator=","]

I still get an error — albeit a different one:

VipsForeignSave: ".csv[separator=","]" is not a known target format

How should this be done? Thank you.

Hi @xamir82,

You're right, this is a libvips bug. I guess it should look for ,([A-Za-z]|]) as the argument separator when parsing those strings.

As a workaround, you can call csvsave directly:

$ vips csvsave image.jpg x.csv --separator , && cat x.csv

Let's tag this as an enhancement.
