Re: [NTG-context] WARNING: File path includes directory that doesn't exist

$ inkscape -V
Inkscape 0.92pre1 unknown (Jul 30 2016)

https://launchpad.net/~inkscape.dev/+archive/ubuntu/trunk

I'm not sure if this version of Inkscape is at fault. It'd be cool if
there was a way to specify the SVG to PDF converter program (e.g., to
use rsvg-converter instead) from the command line.

*Objet :*[NTG-context] lua tables - how do you cope?



This is less a specific question about ConTeXt than a hope for good
advice: I’m maltreating my xml files with a mixture of TeX and Lua. I
want to extract and typeset information in different forms, so I first
collect everything in lua tables, rearrange and order these tables and
typeset the results. All fine and dandy. My problem is that I have to
have tables within tables within tables… you get the picture. One aspect
of Lua that is really bugging me is the fact that associative tables
have no order, which can be a pain in the butt for this kind of
operation. So I have to be careful that I have to use constructs that
will keep the order in which items have been added and loop through them
via ipairs() instead of pairs(). I find it difficult to keep track of
what’s inside my layers upon layers of tables. So my question is: how do
those of you who are more experienced with this kind of question
proceed? Do you have any handy tool to visualize a table? Any tips you
want to share?



Thanks a lot!



Thomas

Arthur, Lukas,

these are both great and very helpful, thanks a lot! I feel bad for not knowing 
table.serialize (which can even be used with the context() function to typeset 
the result, and I really like Lukas’ step-by-step breakdown of the table. Maybe 
I’ll try and think of a nice visual way to represent these Lua tables!

Re: [NTG-context] lua tables - how do you cope?

2016-07-30 Thread Lukas Prochazka

Hello Thomas,

here is my "dump()" I've been using for several years:


function dump(arg, opts) -- .seen, .pfx
  if type(opts) == "string" then print(opts); opts = nil
  elseif opts == true then print("-- (dump)"); opts = nil
  end

  local pfx = opts and opts.pfx
  local seen = opts and opts.seen or {}

  if type(arg) == "table" then
if pfx then pfx = pfx .. "]["
else
  pfx = "["
  --seen = {}
end

seen[arg] = tostring(arg) --true

local keys = {}

do
  -- Sort keys, if all are strings

  local strs_only = true

  for k in pairs(arg) do
if strs_only and type(k) ~= "string" then strs_only = false end

keys[#keys + 1] = k
  end

  if strs_only then table.sort(keys) end
end

for _, key in ipairs(keys) do
  local val = arg[key]

  io.write(pfx .. tostring(key) .. "] = " .. tostring(val) .. "\t(" .. 
type(val) .. ")")

  if type(val) == "table" then
if seen[val] then print(" (seen)")
else
  print()

  dump(val, {pfx = pfx .. tostring(key), seen = seen}) --pfx .. 
tostring(key), seen)
end
  else
print()
  end
end
  else
print(arg)
  end
end


Try:


a = {c = 1, b = 2}; a.a = a

dump(a)
dump(a, "This is 'a'.")


Improvements or parametrization of visualizing style would be possible, of 
course... 

Best regards,

Lukas

  Well, there’s table.serialize from the ConTeXt core, which fits nicely
in the description you quote.

  Alternatively, Mailman, the mailing list software used by this list,

Setups are the way of doing it.

I thought it might be interesting that notes would inherit the setup

have you seen this post?

attacks and is thinking about terminating the service. If I’m not mistaken, for 
the time being, gmane is the only searchable archive of the context mailing 
list, so this would be a major setback. On the garden, there has been a note 
for five or six years (I think) that work is being done on 
archive.contextgarden.net. Maybe the approaching end of gmane would be a good 
motivation to really do this work?

[NTG-context] lua tables - how do you cope?

2016-07-30 Thread Schmitz Thomas A.

This is less a specific question about ConTeXt than a hope for good advice: I’m 
maltreating my xml files with a mixture of TeX and Lua. I want to extract and 
typeset information in different forms, so I first collect everything in lua 
tables, rearrange and order these tables and typeset the results. All fine and 
dandy. My problem is that I have to have tables within tables within tables… 
you get the picture. One aspect of Lua that is really bugging me is the fact 
that associative tables have no order, which can be a pain in the butt for this 
kind of operation. So I have to be careful that I have to use constructs that 
will keep the order in which items have been added and loop through them via 
ipairs() instead of pairs(). I find it difficult to keep track of what’s inside 
my layers upon layers of tables. So my question is: how do those of you who are 
more experienced with this kind of question proceed? Do you have any handy tool 
to visualize a table? Any tips you want to share?

Thanks a lot!

Hi Wolfgang,
That's great, I did not know but it's really convenient.

Re: [NTG-context] \setupalign (protrusion and expansion) in notes

I understand that they have to be a separate stream.

Of course, I didn’t mean a partial alignment should be inherited in the
notes. I meant the alignment properties for the whole document.

I don’t know whether it would make sense to add a key/value pair to
\setupalign, such as "notes=inherit".

My question is more an open one than a feature request. I don’t know
whether it might be useful (because there is a lot about text streams in
ConTeXt that I simply don’t know).

Many thanks for your help,

Pablo
