Vector syntax not working within options?

[kimauth]

Does the vector syntax not work within a set of options or am I just missing how to do this right?

This is what I would like to obtain:

using PGFPlotsX

node_options = @pgf {circle, # and some other options I want to set
                    pin=raw"[pin edge = {out=-70,in=110,semithick,}, color={rgb,1:red,0.0052;green,0.0982;blue,0.3498}] below right:{my_text}"}

# prints as
[circle, pin={[pin edge = {out=-70,in=110,semithick,}, color={rgb,1:red,0.0052;green,0.0982;blue,0.3498}] below right:{my_text}}]

But, within the options of pin I don't want to hardcode the color. So I can do:

using ColorSchemes
blue = ColorSchemes.batlow[0.0]
pin_options = @pgf {pin_edge = {out=-70,in=110, semithick,}, color = blue}
pin = [pin_options, raw"below right:{my_text}"]

and so far, print_tex(pin) does what I want to get:

[pin edge={out={-70}, in={110}, semithick}, color={rgb,1:red,0.0052;green,0.0982;blue,0.3498}] below right:{my_text}

However, using pin within another set of options prints Julia types instead

node_options = @pgf {circle, pin = pin}

# prints as
[circle, pin={PGFPlotsX.Options(OrderedCollections.OrderedDict{Any, Any}("pin_edge" => PGFPlotsX.Options(OrderedCollections.OrderedDict{Any, Any}("out" => -70, "in" => 110, "semithick" => nothing), true), "color" => RGB{Float64}(0.005193,0.098238,0.349842)), true),below right:{my_text}}]

It is possible

PGFPlotsX.jl/src/options.jl

Line 229 in 7b41de7

print_opt(io::IO, v::AbstractVector) = print(io, join(v, ","))

should be changed to also call print_tex on the vs.

I just tried something like

@eval PGFPlotsX begin
    print_opt(io::IO, v::AbstractVector) = print(io, join((print_tex(String, x) for x in v), ","))
end

and I get

julia> node_options
[circle, pin={[pin edge={out={-70}, in={110}, semithick}, color={rgb,1:red,0.0052;green,0.0982;blue,0.3498}] ,below right:{my_text}
}]

I haven't thought anything deep about this though.

It's almost good, but it prints a comma behind the square brackets which tikz doesn't understand. I guess this is sort of special syntax though, as it's options for tikz and not for pgf.

For the sake of completeness, here is something that actually shows a picture (and does work with the first node_options, but not if there is the additional comma):

axis_opts = @pgf {width = "8cm", "axis equal", xmin= -2., xmax=10, ymin = -2., ymax=9., axis_lines="none",}
Axis(axis_opts, [raw"\node", node_options, " at ", Coordinate(0.0, 0.0), "{};"],)

Note that this is TikZ code, not pgfplots. In the manual we suggest that \node commands are just constructed as strings and passed as is.

I sympathize with

don't want to hardcode the color

but I would recommend constructing the string from something like

col = colorant"firebrick3"
sprint(PGFPlotsX.print_opt, col)

which is currently not officially part of the API but should remain supported.

Generally, quite a few building blocks of the package are useful outside pgfplots, and maybe we should make an effort to clean up and export them to emit LaTeX code for general purposes.

[tpapp]

Maybe we should just expose (but not necessarily export) print_opt and print_options as API, and mention them in the manual. They are probably the best solution for composing raw LaTeX directly with the translations this package implements.
