Pass color variable to metapost graphic #540

Can't understand how to pass a color through a variable to a metapost object:

Let's say:

Colors

<DefineColor name="npgray" model="cmyk" c="0" m="0" y="0" k="53"/>
<DefineColor name="darknpgray" model="cmyk" c="0" m="0" y="0" k="21"/>
<DefineColor name="yellow" model="cmyk" c="0" m="10" y="100" k="0"/>

metapost graphic

<DefineGraphic name="roundedcorners">
        save corner; corner := 10;
        filldraw (0, box.height - corner ){down} .. {down}(0,corner) ..
        (corner,0) -- (box.width - corner,0) .. {up}(box.width, corner) --
        (box.width, box.height - corner) .. {left}(box.width - corner, box.height) -- 
        (corner,box.height){left} .. cycle 
        withcolor colors.accent; <<< accent is what I need to change
</DefineGraphic>

Structure

<section secname="01" accent="yellow" >
 <item 1 />
<item 2 />
<item 3/>
</section>

You say:

Variables for MetaPost can be set with <SetVariable>.
<SetVariable
    variable="curcol"
    type="mp:rgbcolor"
    select="'colors_mycolor'"/>
The assignment is evaluated at the beginning of the MetaPost context. Thus curcol is available at the beginning of the graphics.

What do you mean with the beginning of the graphics?

I am defining these elements on top before the page layouts, should I move the graphics just before the page layout after have recorded ?

<!-- OPEN SECTION -->

	<Record element="section">
		<SetVariable variable="secname" select="@secname"/>
		<SetVariable variable="sectiontitleimage" select="img/@file"/>

               <!-- ACCENT COLOR -->
             <SetVariable variable="accent" select="@accent" />

		<PlaceObject allocate="yes" column="4cm" row="10cm" halign="right" frame="solid">
			<Textblock width="15cm" fontfamily="opensecname">
				<Value select="$secname"/>
			</Textblock>
		</PlaceObject>
		<ProcessNode select="subsection"/>
	</Record>

    <DefineGraphic name="accent-roundedcorners">
        save corner; corner := 10;
        filldraw (0, box.height - corner ){down} .. {down}(0,corner) ..
        (corner,0) -- (box.width - corner,0) .. {up}(box.width, corner) --
        (box.width, box.height - corner) .. {left}(box.width - corner, box.height) -- 
        (corner,box.height){left} .. cycle 
        withcolor colors.accent;
	</DefineGraphic>

Useless to say it doesn't compile... 🤔

Thanks! 🙏

Hi @pgundlach

I tried to replicate the issue, and it wasn't working till I copied and pasted one to one each variables.
Now the code, that I suppose replicates my structures, is working:

data.xml

<data>
    <Parent title="SP Color Test" accent="spyellow">
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>1</Baby>
            </Nephew>
        </Child>
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>2</Baby>
            </Nephew>
        </Child>
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>3</Baby>
            </Nephew>
        </…

You can use the metapost macro spcolor:

<Layout xmlns="urn:speedata.de:2009/publisher/en"
    xmlns:sd="urn:speedata:2009/publisher/functions/en">
    <Pageformat height="8cm" width="10cm" />
    <DefineColor name="mygray" model="gray"  g="80"/>
    <DefineColor name="transparentorange" model="cmyk"  c="0" m="45" y="87" k="0" alpha="0.4"/>

    <DefineGraphic name="box">
        fill box withcolor spcolor("mygray");
    </DefineGraphic>

    <DefineGraphic name="alphabox">
        fill box withcolor spcolor("transparentorange");
    </DefineGraphic>

    <Record element="data">
        <PlaceObject>
            <Box height="4" width="4"  graphic="box"/>
        </PlaceObject>
        <PlaceObject>
            <Box height="4" width="4"  backgroundcolor="blue"/>
        </PlaceObject>
        <PlaceObject row="3" column="3" allocate="no">
            <Box height="4" width="4"  graphic="alphabox"/>
        </PlaceObject>
    </Record>
</Layout>

See https://github.com/speedata/publisher/tree/develop/qa/metapost/spcolor and https://doc.speedata.de/publisher/en/advancedtopics/advancedtopics-metapostgraphics/#_metapost_macros

Does this help?

Hi @pgundlach

I am going to test this later and I'll let you know!

Definitely I didn't get it! 🤦‍♂️

	<DefineGraphic name="roundedcorners"> save corner; corner := 10; filldraw (0, box.height -
		corner ){down} .. {down}(0,corner) .. (corner,0) -- (box.width - corner,0) ..
		{up}(box.width, corner) -- (box.width, box.height - corner) .. {left}(box.width - corner,
		box.height) -- (corner,box.height){left} .. cycle withcolor colors.spcolor("@accent"); </DefineGraphic>

Output:

publisher.lua:882: bad argument #1 to 'setmetatable' (table expected, got nil)
Error: [page 2] Executing  save corner; corner := 10; filldraw (0, box.height -
                corner ){down} .. {down}(0,corner) .. (corner,0) -- (box.width - corner,0) ..
                {up}(box.width, corner) -- (box.width, box.height - corner) .. {left}(box.width - corner,

I'm afraid I need some sort of value in order to continue,
so I've tentatively inserted `0'. You may want to
delete this zero and insert something else;

Doesn't change anything if is withcolor colors.spcolor("@accent"); or withcolor spcolor("@accent"); ; perhaps it is not possible pass a variable to metapost... 🤷‍♂️

Which version of the speedata Publisher are you using?

<Layout xmlns="urn:speedata.de:2009/publisher/en"
    xmlns:sd="urn:speedata:2009/publisher/functions/en">
    <DefineColor name="@accent" model="spotcolor" colorname="Pantone 116 C"/>

    <DefineGraphic name="roundedcorners"> save corner; corner := 10; filldraw (0, box.height -
      corner ){down} .. {down}(0,corner) .. (corner,0) -- (box.width - corner,0) ..
      {up}(box.width, corner) -- (box.width, box.height - corner) .. {left}(box.width - corner,
      box.height) -- (corner,box.height){left} .. cycle withcolor spcolor("@accent");
     </DefineGraphic>
    <Record element="data">
    <PlaceObject>
      <Box height="4" width="4" graphic="roundedcorners" />
    </PlaceObject>
    </Record>
</Layout>

works fine here. Does this layout work with your installation?

Can have any relevance that I am using it on FreeBSD rather than Linux or Windows?

Spot colors need a Pro plan

Since you compile it yourself, use SDPRO=yes rake build and SDPRO=yes rake buildlib to compile the sp binary and library.

There is an error message in the log file:

Error: [page 1] spot colors need a Pro plan

It worked even on my layout! 🎇 🎇 🎇

Besides the spot color, was the issues caused by the standard version?

Hi Patrick,

I was able to pass the variable from data to the layout but I can't go all way down to the children nodes, perhaps because I made it convoluted, can the following snippet being improved? 🙏

I was able to get the color by using two variables:
layout.xml

<Layout xmlns="urn:speedata.de:2009/publisher/en"
    xmlns:sd="urn:speedata:2009/publisher/functions/en">

    <DefineColor name="npyellow" model="RGB" r="255" g="178" b="25" alpha="100"/>
    <DefineColor name="npgreen" model="RGB" r="0" g="200" b="25" alpha="100"/>

    <DefineGraphic name="r"> fill box withcolor spcolor(accent); </DefineGraphic>

    <Record element="data">
        <ProcessNode select="*"/>
    </Record>

    <Record element="box">

        <SetVariable variable="color" select="@accent" />
        <SetVariable variable="accent" select="$color" type="mp:string" />

        <PlaceObject>
            <Box height="15" width="15" graphic="r" />
        </PlaceObject>

        <Message select="$color" />

        <PlaceObject>
            <Textblock>
                <Paragraph color="{$color}">
                    <Value select="@accent" />
                </Paragraph>
            </Textblock>
        </PlaceObject>
    </Record>

</Layout>

data.xml

<data>
    <box accent="npgreen" />
</data>

Thanks! 🙏

Eh eh... 😁

I should sent the original code... 🤔

The point is if I move this variable inside a group the compilation fails:
<SetVariable variable="accent" select="$color" type="mp:string" />

the issue above is partially resolved, I did not reuse the same names for some variables even though do and serve the same scope, so I got no errors however I am still stuck here: #541 (reply in thread)

Hi @pgundlach

After dozen and dozen of attempts I end up with this conclusion: variables that contain type=mp:string, such as:
<SetVariable variable="accent" select="$color" type="mp:string" />, aren't read or recognized inside a group; this is why I can't get the "accent" color working withing any group.

In fact:

Call "SetVariable" from layout <<< regular variable
Call "SetVariable" from layout <<< variable 'mp:string'
Call "Message" from layout
Message: "color-group: npyellow" <<< regular variable
Call "Message" from layout
Error: [page 6] Variable "accent" undefined <<< variable 'mp:string'
Message: "nil"

I'd say more, because perhaps I might have spotted out a potential bug that is related with groups, mp:string and the new XPath parser lxml.

In the previous block variables are defined outside the group, in the following block are defined inside the group:

<SetVariable variable="colorgroup" select="../@accent" />
<SetVariable variable="accentgroup" select="$colorgroup" type="mp:string" />

<Message select="concat('var-colorgroup: ', $colorgroup)" />
<Message select="concat('Accent: ',$accentgroup)" />

And this is the output:

I am having these issues on version 4.15.16 both pro and regular, thanks! 🙏

After dozen and dozen of attempts I end up with this conclusion: variables that contain type=mp:string, such as:
, aren't read or recognized inside a group; this is why I can't get the "accent" color working withing any group.

the type="mp:string" variables are not available to the regular layout (only to metapost), so
Error: [page 2] Variable "accentgroup" undefined
is expected.

I am stil confused what is working and what is broken. Could you open a new issue for each problem?

Hi @pgundlach sorry for being so confused.

I am going to replicate the issues on a smaller base code and to open the bug reports needed. Perhaps next week, I need to figure out how to shrink the code first! 🙏

Hi @pgundlach

I tried to replicate the issue, and it wasn't working till I copied and pasted one to one each variables.
Now the code, that I suppose replicates my structures, is working:

data.xml

<data>
    <Parent title="SP Color Test" accent="spyellow">
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>1</Baby>
            </Nephew>
        </Child>
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>2</Baby>
            </Nephew>
        </Child>
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>3</Baby>
            </Nephew>
        </Child>
        <Child>
            <Nephew>
                <Baby>This is box: </Baby>
                <Baby>4</Baby>

Perhaps my issue is likely the same, a typo in some variables... 🤔
Mmm... 🤷‍♂️

Your example works fine here

BTW: when you use something like ../@accent you need the lxpath XPath parser.

Ok, this has been solved, there was a GIANT PEBCAK and I was trying to recycle the same "metapost" variable for an element that wasn't a metapost graphic.

The funky part is that solving this issue revealed another one that I was thinking it was already solved... 🤦

But this is another discussion...
