Re: [NTG-context] How to write readable source files?
On 2021-05-29, Hans Hagen wrote: > so what does vim expect? isn't there some kind of common format for lexers? The output I need is very simple: syn keyword Group1 ... syn keyword Group2 ... ... where Group1, Group2, ... define arbitrary groups of keywords. For instance, for MetaFun I currently have `mpDef` (MetaPost def macro), `mpVardef` (MetaPost vardef), `mpPrimaryDef`, `mpSecondaryDef`, `mpTertiaryDef`, `mpCommand`, `mpConstant`, `mpVariable`, `mpType`, `mpNewInternal`, and a few others. An excerpt from the current syntax file looks like this: ... " mp-base.mpiv syn keyword mpNumExp graypart syn keyword mpType graycolor greycolor syn keyword mpConstant cyan magenta yellow " mp-butt.mpiv syn keyword mpDef predefinedbutton some_button syn keyword mpConstant context_butt " mp-char.mpiv syn keyword mpDef flow_begin_chart flow_begin_sub_chart syn keyword mpDef flow_chart_draw_comment flow_chart_draw_exit ... syn keyword mpVardef flow_xy_on_grid flow_xy_right flow_xy_top syn keyword mpVardef flow_y_on_grid syn keyword mpVariable flow_arrowtip flow_chart_background_color syn keyword mpVariable flow_chart_offset flow_comment_offset syn keyword mpVariable flow_connection_arrow_size ... This fine-grained classification allows for great flexibility when defining syntax highlighting, because each group can have different properties (and the user can customize that), although by default several groups are highlighted in the same way (e.g., all macros have the same highlighting by default).

I just checked some older projects and the older versions. I used a
mix between
- linear_shade…
- withshading("linear"…
- withshademethod "linear" …
depending on the age of the project. And I fail to find a project
using transparent shading where the transparency is done in context.
I could not get it working now on the older versions. Maybe you're
right and it has never worked the way I thought it had. Sorry for
the noise.

That's basically shading to the background colour, which gives the
impression of transparency. I've been using that. Works most of the
time. But it's not the same. See the attached file and compare.
I guess I'll keep using the external file overlay then.

For the old implementation (pre 2016-ish) I had a working solution
because shading to transparent colours just worked (at least in my
case of a simple transparent shade, nothing fancy), but not so any
longer. With the new implementation I couldn't get it working. But
we discussed that at some point in the past. I believe the gist of
it was “shade-to-transparent is gone”.
i'm not ssure what shade to transparency means
I mean a shade from a colour (e.g. black) to transparent. For
instance this used to work pre 2016:
\setupbackgrounds [page] [background=color, backgroundcolor=lightgray]
\definecolor [trans] [a=multiply, t=1, s=1]
\starttext
\startMPcode
path p; p:=fullsquare xyscaled (5cm, 5cm);
fill p
withshading("linear", ulcorner p, llcorner p)
withfromshadecolor \MPcolor{white}
withtoshadecolor \MPcolor{trans};
\stopMPcode
\stoptext
The shade goes from white to transparent (here lightgray, that's the
page colour). I assume you have an older context laying around to
run the example above.
... shades can be transparent currently
Yes, but the *whole* shade is made transparent. Currently I don't
know a way to shade from e.g. black to transparent (no colour). The
colour involved in the shading can't have transparency, or if they
do one has to use \MPcoloronly to get rid of the transparency part.
hm, I'm puzzled as a shade doesn't go between colors + transparent but
from one color to another (in the same color space) and transparency is
just a different mechanism
maybe it was some side effect of chosen values / vectors that gave the
combined impression (which is why i want to see the pdf made by context
that you use as reference)
anyway, it helps to be in the same color space
\setupbackgrounds [page] [background=color, backgroundcolor=lightgray]
\starttext
\startuseMPgraphic{test}
graycolor white; white := 1 ;
fill OverlayBox
withshademethod "linear"
withshadedirection shadedup
withshadefactor 1.5
withshadecolors (.85white,white)
% withtransparency (multiplytransparent,.7)
withtransparency (normaltransparent,.7)
\stopuseMPgraphic
\defineoverlay[test][\useMPgraphic{test}]
\framed
[align=middle,background={foreground,test}]
{\samplefile{sapolsky}}
\stoptext
So the above old syntax roughly translated to the current
implementation:
\setupbackgrounds [page] [background=color, backgroundcolor=lightgray]
\definecolor [trans] [a=multiply, t=1, s=1]
\starttext
\startMPcode
path p; p:=fullsquare xyscaled (5cm, 5cm);
fill p
withshademethod "linear"
withshadevector (3, 0)
%% since "trans" contains transparency, one has to use
\MPcoloronly withshadecolors (white, \MPcoloronly{trans})
withtransparency (.5, .5)
%% withtransparency \MPtransparency{trans}
;
\stopMPcode
\stoptext
.. so how did that old file (uncompressed pdf) look like then
Just run the first example with an old context version. The file
gradient-t from my last mail was created using inkscape as I don't
want a single project to depend on two different context versions.
you're kidding ... i have no old context on my machine

Re: [NTG-context] gray scale conversion of colored text

Hi,
I currently have a problem with the conversion of some mp graphics into
gray scale. The mp graphics themself look great, but *text is always
converted to black*, regardless of its real color. Is there a way to fix
this?
Sorry, I made a mistake. The text that is used inside MP has the correct
gray value. Only the ConTeXt part always uses black as textcolor.
So my problem is, that want to use colored text in a non colored document.
Something like
\setupcolors[conversion=always]
\starttext
\setbox\scratchbox\hbox{An example text.}%
\bgroup\graycolor[cyan]\copy\scratchbox\egroup
\startcolor[green]\copy\scratchbox\stopcolor
\box\scratchbox
\stoptext
This always gives me black text, as color is not activated. How do I get
the correct gray scale values for the text?
