Command line stdin conversion about svgbob

[ivanceras]

Make sure you installed svgbob_cli via cargo install -f svgbob_cli.
Invoke the command with svgbob
Trying out your example:

$> echo "+--+\n| |\n+--+" | svgbob

Thanks for looking into that. I also get some result with the example you tested, but here is what the svg you posted looks like :

(in the svg you can also see that the \n are actually written as <text>n</text>)
When using an external file (with actual newline characters) :

I get something slightly different with the same command line, so I will perform the installation like you said, but I think the newline character will still be handled the same way :

Hi, it looks like a huge bug, probably with the added " as escaping character to be not interpreted as graphics. I've to look at this further.

@yhql it looks like this is not an issue with svgbob at all, but echo is sending literal "\n". That needs to be an actual line. Try putting -e instead with echo -e "+--+\n| |\n+--+" | svgbob.
Alternatively you can also try printf "+--+\n| |\n+--+" | svgbob as stated here https://stackoverflow.com/questions/8467424/echo-newline-in-bash-prints-literal-n

Thanks for the info. Sadly as I'm on windows the echo command does not have any special flags that would help.
I did try the following trick :
echo "+--+" & echo "| |" & echo "+--+" | svgbob
which almost does the job : the drawing is correct but there seems to be no way of getting rid of the " characters in the result.

If you're ok with it I could try to make svgbob accept strings as first arguments so that it handles the \n and others by itself, rather than let the terminal deal with it (because I don't see any way around on Windows).
