keep Doctype-Declaration

[JoKalliauer]

I know some decline Doctype-Declaration (DTD): https://jwatt.org/svg/authoring/#doctype-declaration

But I personally prefer Doctype-Declaration, because https://validator.w3.org/ has a different Check for SVGs with DTD, and it does not display any warning. Is there an option to keep DTD?

scour keeps it and for svgo is an option for keeping DTD:

$ svgo -i input.svg -o output.svg --disable=removeDoctype

Or you might can convince me that SVGs should not have DTD.

[RazrFalcon]

It's not possible. I can create a new one if you need.

[JoKalliauer]

I would like such option because I always reinsert it manually, also I think options should kept at a minimal level to be clear for new users.

[RazrFalcon]

options should kept at a minimal level

What do you mean?

[JoKalliauer]

Nothing important. I mean that

svgcleaner.exe --help

svgcleaner could help you to clean up your SVG files from the unnecessary data.

A complete documentation can be found here: https://github.com/RazrFalcon/svgcleaner/blob/master/docs/svgcleaner.adoc

USAGE: svgcleaner [FLAGS] [OPTIONS]

<FLAG> can contain values: true, false, yes, no, y, n

EXAMPLES: clean a file with default options: svgcleaner in.svg out.svg

clean a file with custom options:
svgcleaner --indent=2 --paths-coordinates-precision=5 --join-arcto-flags=yes in.svg out.svg

clean a file without default options:
svgcleaner --no-defaults --remove-comments=yes in.svg out.svg

clean a stream using UNIX pipes:
cat in.svg | svgcleaner -c - > out.svg

FLAGS: -h, --help Print help information -V, --version Print version information -c, --stdout Print result to the standard output --no-defaults Reset default flags to 'no' --multipass Clean a file multiple times --allow-bigger-file Allow bigger file --copy-on-error Copy an original file to the destination on error --quiet Show only warnings and errors

ARGS:

Input file Output file ``` is quite long (which is perfect for advanced users, like me), but for new users it is not easy to not find the function the users is searching for, especially if he/she does not have the knowledge to understand the explanations. (But that's not critics, that is just that you maybe have to do a tradeoff.) But If you ask me: I would like the option `--removeDoctype no` (or `keepDTD` or `insertDTD`, or something similar)

[RazrFalcon]

Ok. I will add it.

for new users it is not easy to not find the function

That's why the GUI exists. I don't plan to simplify the help output for now.

Just for Information:

Since some weeks https://validator.w3.org/check only checks SVGs with Doctype (or you have to specify it manually before the check)

See f.e. :https://validator.w3.org/check?uri=https%3A%2F%2Fcommons.wikimedia.org%2Fwiki%2FSpecial%3AFilepath%2FSVG_example_path.svg&ss=1#source
