Introduction
!! W A R N I N G !!
!! THIS CODE IS HIGHLY EXPERIMENTAL !!
!! THIS CODE WORKS ONLY UNDER LINUX !!
!! THIS CODE WORKS ONLY WITH luatex 0.42 !!
!! THIS CODE WORKS ONLY WITH ConTeXt version: 2009.07.17 17:23
luatex_lunatic is a modification of lua side of luatex to host a python interpreter inside lua (see lunatic-python) .
I have made a set of patches because :
- by design, lua in luatex doesn't permit dynamic loading ("Dynamic loading of .so and .dll files is disabled on all platforms." see "LUA changes" in manual/luatexref-t.pdf of src and/or svn dist.)
- to prevent symbols collisions between luatex and an arbitrary library
A python interpreter hosted in luatex can make easier to use existing python's bindings; also the ctype modules (included in python releases at from 2.5 version) permits a binding to a .so without using SWIG or similar (almost like loadlib of lua) .
As general rule, I want the smallest set of patches ; so, for example, I have choose to not use a system libpng, even if it's easy to modify build.sh. to do so.
Also, I'm not concerned about portability: I will talk only about Linux .
Please note that luatex_lunatic was born to answer to (my) question "Can I apply lunatic to luatex ?" and nothing else.
Every others meanings can be interestring, but are not mine , and I will not partecipate to any discussion about that.
How to
I prefear to put a bash script that can help to compile a luatex-lunatic binary. It's clear that some skills are needed, so I hope in this way to avoid useless questions . Of course, I will try to correct all errors .
The trick is hide all, then unhide what is needed, then make only what is needed and in the end re-compile luatex .
The changes are :
- in build.sh.linux add
28a29,36 > export CONFIG_SHELL=/bin/bash > CFLAGS="-g -O2 -Wno-write-strings -fvisibility=hidden" > CXXFLAGS="$CFLAGS -fvisibility-inlines-hidden" > export CFLAGS > export CXXFLAGS > > >
- in source/texk/web2c/luatexdir/lua51/loadlib.c
69c69 < void *lib = dlopen(path, RTLD_NOW); --- > void *lib = dlopen(path, RTLD_NOW|RTLD_GLOBAL);
- in source/texk/web2c/Makefile.in:
98c98 < @MINGW32_FALSE@am__append_14 = -DLUA_USE_POSIX --- > @MINGW32_FALSE@am__append_14 = -DLUA_USE_LINUX 1674c1674 < $(CXXLINK) $(luatex_OBJECTS) $(luatex_LDADD) $(LIBS) --- > $(CXXLINK) $(luatex_OBJECTS) $(luatex_LDADD) $(LIBS) -Wl,-E -uluaL_openlibs -fvisibility=hidden -fvisibility-inlines-hidden -ldl -lreadline -lhistory -lncurses
So, first compile as usual
$>build.sh
Then use trick.zip" to unhide symbols from liblua51.a and recompile luatex (put it at the same level of build.sh) .
Python packages
These are python packages that are not in standard libraries ; "✔" means that I have made only small lua wrapper .
For these, I still have to decide what todo.
- TO FIX ; pygegl (I like its syntax, but need too much and it's easy only in python)
- TODO: binding of libtiff with ctypes (or use gdal ?)
- TODO :gle (for Massimiliano "Max" Dominici, GUIT)
- TODO : using the binding of VIPS
Bindings
These are shared lib that come with native python binding, or eventually I have made a wrapper using ctypes .
- ghostscript 8.64 ✔ here
- graphviz 2.24.0 ✔ here
- ImageMagick-6.4.9 with pythonmagickwand ✔ here
- fontforge 20090224 ✔ here Useful to check symbols collision, and if one want to play with the last fontforge, eg to draw the outline of a glyph .
- R-2.8.1 with rpy2-2.0.3 (For Maurizio "Mau" Himmelman , GUIT) ✔ here (someone says also considering-r-as-python-supplement ) .
- quantlib 0.9.7 ✔ (need an example with output in pdf)
- dbxml-2.4.16 (and sqlite) ✔ here
Dedicated systems
When we have a huge and coordinate set of *so with python binding, it' better to dedicate a specific luatex-lunatic . As example I choose sagemath and ROOT .
SageMath
From sagemath :
Sage is a free open-source mathematics software system licensed under the GPL. It combines the power of many existing open-source packages into a common Python-based interface.
Given that sagemath
is rooted on a CPtyhon , we can try to use sagemath as "plugin" for luatex
instead of use latex as external process of sagemath.
sagemath comes with own python, and we must use it; in this case I put all stuffs under a separated lunatic-python-SAGEMATH .
HOME_LUN=/opt/luatex/luatex-lunatic cd $HOME_LUN cp -r lunatic-python lunatic-python-SAGEMATH cd lunatic-python-SAGEMATH ## ## We prepare new bridge ## rm -r build $HOME_LUN/sage/local/bin/python setup.py build cd $HOME_LUN mkdir tests-SAGEMATH && cd tests-SAGEMATH ## ## I have already installed prev. python.so, I don't want mess things ## ln -s ../lunatic-python-SAGEMATH/build/lib.linux-i686-2.5/python.so ln -s ../luatex/build/texk/web2c/luatex ## ## now we need to setup sagemath ## cd $HOME_LUN/sage/local/bin . sage-env cd $HOME_LUN
We need also a first run of sagemath:
cd sage ./sage ## ## now exit from sage ##
That is .
Now we need a stub, because usually sage is used as an interactive shell:
## sagestub.py from sage.all_cmdline import *
OK let's start with an example with mixed code (or, better, 'messed code'):
\startluacode function test_ode(graphout) require("python") pg = python.globals() SAGESTUB = python.import("sagestub") sage = SAGESTUB.sage python.execute([[ def f_1(t,y,params): return[y[1],-y[0]-params[0]*y[1]*(y[0]**2-1)] ]]) python.execute([[ def j_1(t,y,params): return [ [0,1.0],[-2.0*params[0]*y[0]*y[1]-1.0,-params[0]*(y[0]*y[0]-1.0)], [0,0] ] ]]) T=sage.gsl.ode.ode_solver() T.algorithm="rk8pd" f_1 = pg.f_1 j_1 = pg.j_1 pg.T=T python.execute("T.function=f_1") T.jacobian=j_1 python.execute("T.ode_solve(y_0=[1,0],t_span=[0,100],params=[10],num_points=1000)") python.execute(string.format("T.plot_solution(filename='%s')",graphout )) end \stopluacode \def\TestODE#1{% \ctxlua{test_ode("#1")}% \startcombination[2*1] {%foo \vbox{\hsize=8cm Consider solving the Van der pol oscillator $x''(t) +ux'(t)(x(t)^2-1)+x(t)=0 $ between $t=0$ and $t= 100$.

ROOT (CERN)
ROOT -- an Oject-Oriented Data Analysis Framework -- is explained in
Wikipedia:
ROOT is an object-oriented program and library developed by CERN. It was originally designed for particle physics data analysis and contains several features specific to this field, but it is also commonly used in other applications such as astronomy and data mining.
For more infos, see here (here for python stuffs).
Under Linux installation is not difficult at all, so in this case I choose to not create a luatex-lunatic apart, as done above for sagemath.
See an example here .
ConTeXt mkIV examples
Here I will collect some tex snippets, just to show some ideas.
Scipy
Watch how python code z = x*np.exp(-x**2-y**2) is translated in lua code z = x.__mul__( np.exp( (x.__pow__(2).__add__(y.__pow__(2))).__neg__() ) )
Python Imaging Library (PIL)
ROOT
This example shot how to literally embed original python source code .
We can do a bit better: separate python code from lua code .
Save this in test-ROOT1.py (so it's also easy to test) :
from ROOT import TCanvas, TGraph ,TGraphErrors,TMultiGraph from ROOT import gROOT from math import sin from array import array def run(filename): c1 = TCanvas("c1","multigraph",200,10,700,500) c1.SetGrid() # draw a frame to define the range mg = TMultiGraph() # create first graph n = 24; x = array('d',range(24)) data = file('data').readlines() for line in data: line = line.strip() y = array('d',[float(d) for d in line.split()]) gr = TGraph(n,x,y) gr.Fit("pol6","q") mg.Add(gr) mg.Draw("ap") #force drawing of canvas to generate the fit TPaveStats c1.Update() c1.Print(filename)
Here file 'data' is a 110 lines file with 24 floats values space separated,
ie
20.6000 19.4000 19.4000 18.3000 17.8000 16.1000 16.7000 21.1000 23.3000 26.1000 26.1000 27.2000 27.8000 28.3000 28.3000 27.2000 25.6000 22.8000 21.7000 21.7000 21.7000 21.7000 21.7000 21.7000 .
Now a tex file, with a simple layer in lua as interface for python:
ImageMagick
ImageMagick® (here) is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. There are at least two python bindings, and this time I consider PythonMagickWand which is a binding "ala" ctypes way .
Code is simple
\usetypescriptfile[type-gentium] \usetypescript[gentium] \setupbodyfont[gentium,10pt] \setuppapersize[A5][A5] \setuplayout[height=middle,topspace=1cm,header={2\lineheight},footer=0pt,backspace=1cm,margin=1cm, width=middle] \startluacode function testimagemagick(box,t) local w local h local d local f local res = 118.11023622047244094488 -- 300 dpi local opacity = 25 local sigma = 15 local x = 10 local y = 10 require("python") pg = python.globals() PythonMagickWand = python.import("PythonMagickWand") w = math.floor((tex.wd[box] / 65536 ) / 72.27 * 2.54 * res ) h = math.floor(((tex.ht[box] / 65536) + (tex.dp[box] / 65536)) / 72.27 *2.54 *res ) f = string.format("%s.png",t) wand = PythonMagickWand.NewMagickWand() background = PythonMagickWand.NewPixelWand(0) -- PythonMagickWand.MagickNewImage(wand,w,h,background) PythonMagickWand.MagickNewImage(wand,w,h,background) PythonMagickWand.MagickSetImageResolution(wand,res,res) PythonMagickWand.MagickSetImageUnits(wand,PythonMagickWand.PixelsPerCentimeterResolution) PythonMagickWand.MagickShadowImage(wand,opacity,sigma,x,y) PythonMagickWand.MagickWriteImage(wand ,f) print(w,h,f) end \stopluacode \def\testimagemagick[#1]{% \getparameters[imagemagick][#1]% \ctxlua{testimagemagick(\csname imagemagickbox\endcsname,"\csname imagemagickfilename\endcsname")}% } \newcount\shdw \long\def\startShadowtext#1\stopShadowtext{% \bgroup% \setbox0=\vbox{#1}% \testimagemagick[box=0,filename={shd-\the\shdw}]% %% \defineoverlay[backg][{\externalfigure[shd-\the\shdw.png]}]% \framed[background=backg,frame=off,offset=4pt]{\box0}% %%\framed{\box0} \global\advance\shdw by 1% \egroup% } \starttext \startTEXpage% \startShadowtext% \input tufte \stopShadowtext% \stopTEXpage \stoptext
And here is the result:
Fontforge
In this example, we will use Metapost to draw a bezier curve of a glyph (Note: starting from Metapost 1.200 it is now possible to get the actual path drawing routines from a font glyph, so this example is only to show how to translate a path in metapost).
We will use 3-layer approach:
- a python layer that export a class,
- a lua layer to manage objects of this class
- a (con)TeX(t) layer that exports macros, because tex works very well with macros .
Let's start with python code, test-fontforge.py:
import sys import fontforge class simpledraw(object): def __init__(self,font_file): self.font = fontforge.open(font_file) def getcurve(self,letter): self.glname = letter res_Array = [] res = dict() try : #glyph_letter = [ g for g in self.font.glyphs() if g.glyphname == self.glname][0] g = self.font[letter] except Exception ,e : res['err'] = str(e) res_Array.append(res) return res_Array layer_idx = 0; for layer_name in g.layers: layer = g.layers[layer_name] for contour_idx in range(len(layer)): res = dict() contour = layer[contour_idx] contour_name = contour.name res['name'] = contour.name res['is_quadratic'] = contour.is_quadratic res['closed'] = contour.closed res['points'] = [(p.x,p.y,"%i" %p.on_curve) for p in contour ] res['design_size'] = self.font.design_size res['em'] = self.font.em res_Array.append(res) return res_Array def drawmpostpath(self,letter): res_Array = self.getcurve(letter) state = 0 paths = '' for res in res_Array: temp = '' for p in res['points'] : if p[2]=='1' : if state == 1 : temp = temp + '-- (%s,%s)' %(p[0] ,p[1]) ; state = 1; continue else: temp = temp + '.. (%s,%s)' %(p[0] ,p[1]) ; state = 1; continue if state == 1 : temp = temp + ' .. controls (%s,%s)' %(p[0],p[1]) ; state =2; continue if state == 2 : temp = temp + ' and (%s,%s) ' %(p[0],p[1]) ; state =0; continue if res['closed'] : if state == 1 : temp = 'draw ' + temp[2:] + " -- cycle;\n" else: temp = 'draw ' + temp[2:] + " .. cycle;\n" else: temp = 'draw ' + temp[2:] + ";\n" paths = paths + temp return paths def drawmpostpoints(self,letter): res_Array = self.getcurve(letter) dots = '' for res in res_Array: temp = '\n'.join( ["drawdot %s;" %str((p[0],p[1])) for p in res['points'] if p[2] == '1'] ) + "\n" dots = dots + temp return dots if __name__ == '__main__': s = simpledraw("lmmono10-regular.otf") #res = s.getmpostpointsSugar('C') #print res #print s.getmpostoutline('C') print s.getcurve('e') print s.drawmpostpath('e') print s.drawmpostpoints('e')
Note the '__main__' check, so we can test this class from python.
Next lua layer, which in this case is embed in a tex file:
\setupcolors[state=start] \startluacode function testFontforge(fontfile,letter) require("python") testoutlines = python.import("test-fontforge") s = testoutlines.simpledraw(fontfile) g = s.drawmpostpath(letter) p = s.drawmpostpoints(letter) --print( string.format("\%s = \%s ==", letter,g )) tex.sprint(tex.ctxcatcodes,"\\startMPcode") tex.sprint(tex.ctxcatcodes,"pickup pencircle scaled 1pt;") tex.sprint(tex.ctxcatcodes,string.format("\%s",g) ) tex.sprint(tex.ctxcatcodes,"pickup pencircle scaled 8pt;") tex.sprint(tex.ctxcatcodes,string.format("\%s",p) ) tex.sprint(tex.ctxcatcodes,"\\stopMPcode") end \stopluacode \def\Outline[#1]{% \getparameters[test][#1]% \ctxlua{testFontforge("\testfontfile", "\testletter")}% } \starttext \startTEXpage \Outline[letter={C}, fontfile={lmmono10-regular.otf}]% \Outline[letter={o}, fontfile={lmmono10-regular.otf}]% \Outline[letter={n}, fontfile={lmmono10-regular.otf}]% \Outline[letter={T}, fontfile={lmmono10-regular.otf}]% \Outline[letter={e}, fontfile={lmmono10-regular.otf}]% \Outline[letter={X}, fontfile={lmmono10-regular.otf}]% \Outline[letter={t}, fontfile={lmmono10-regular.otf}]% \stopTEXpage \stoptext
Here we use tex.sprint(tex.ctxcatcodes,"\\stopMPcode") to inject tex code (actually Metapost code) into TeX parser .
\Outline is the TeX layer: of course one can write \Outline and testFontforge in a different manner to avoid use of tex.sprint(..)
And this is the result:
Ghostscript
There are essentially 2 kind of use of ghostscript :
- convert an existing eps / ps file in pdf ;
- use a program in postscript that take an input, do something and make a ps output ( e.g. a barcode/label generator ).
For the first case, we consider an implementation of eps2pdf, being ps2pdf virtually the same .
Actually there is not a python binding of ghostscript, so we build a simple wrapper
using ctypes module.

The tex code
\startluacode function testgs(epsin,pdfout) require("python") gsmodule = python.import("testgs") ghost = gsmodule.gs() ghost.appendargs('-q') ghost.appendargs('-dNOPAUSE') ghost.appendargs('-dEPSCrop') ghost.appendargs('-sDEVICE=pdfwrite') ghost.InFile = epsin ghost.OutFile = pdfout ghost.run() end \stopluacode \def\epstopdf#1#2{\ctxlua{testgs("#1","#2")}} \def\EPSfigure[#1]{%lazy way to load eps \epstopdf{#1.eps}{#1.pdf}% \externalfigure[#1.pdf]% } \starttext \startTEXpage \startcombination[2*1] {\EPSfigure[tiger]}{\ss tiger.eps} {\EPSfigure[golfer]}{\ss golfer.eps} \stopcombination \stopTEXpage \stoptext
Another example:
here we use a library to generate barcodes (see here) .

Graphviz
Graphviz is a Graph Visualization Software .
Standard distribution comes with several binding (lua and python among others) so it's not difficult to integrate in luatex lunatic .
In this example, we draw a graph of the nodes of
\def\StudyBox#1{% \startluacode require "python" gv = python.import("gv") g = gv.digraph("G") gv.setv(g,'rankdir','LR') nodes = nodes or {} local nd = {}; local kd = {}; local k = 0; local function nodesprint(head,n) while head do local id = head.id local oldn = n ndlbl = string.format("nd_\%03d",k) texio.write_nl(string.format("id=\%s, ndlbl=\%s",id,ndlbl)) if id == node.id("vlist") then k = k + 1 nd[n] = gv.node(g,ndlbl) res = gv.setv(nd[n],"shape","record") res = gv.setv(nd[n],"label",tostring(k) ..

R
R is a language and environment for statistical computing and graphics (see here) .
RPy is a very simple, yet robust, Python interface to the R Programming Language (see here) .
As example, let's try to plot a discrete distribution of probability for a set of pseudorandom number (around 100000 samples) .
import rpy2.robjects as robjects import rpy2.rinterface as rinterface class density(object): def __init__(self,samples,outpdf,w,h,kernel): self.samples = samples self.outpdf= outpdf self.kernel = kernel self.width=w self.height=h def run(self): r = robjects.r data = [int(k.strip()) for k in file(self.samples,'r').readlines()] x = robjects.IntVector(data) r.pdf(file=self.outpdf,width=self.width,height=self.height) z = r.density(x,kernel=self.kernel) #r.plot(z[0],z[1],xlab='',ylab='',xlim=robjects.IntVector([0,2**16-1])) r.plot(z[0],z[1],xlab='',ylab='') r['dev.off']() if __name__ == '__main__' : dens = density('u-random-int','test-001.pdf',10,7,'o') dens.run()

dbxml
From site (see here) :
Oracle Berkeley DB XML is an open source, embeddable XML database with XQuery-based access to documents stored in containers and indexed based on their content. Oracle Berkeley DB XML is built on top of Oracle Berkeley DB and inherits its rich features and attributes. Like Oracle Berkeley DB, it runs in process with the application with no need for human administration. Oracle Berkeley DB XML adds a document parser, XML indexer and XQuery engine on top of Oracle Berkeley DB to enable the fastest, most efficient retrieval of data.
As test, we can use a dump from wikiversity (see here) .
First we build the container 'Data.dbxml' in the directory "wikienv" (that must exists) :

We use this modules to retrive a page, given a title (it can be also used as basis to build more complex queries, but for now it's adeguate ):

Here here the result:
One can also use sqlite that comes with python to query for titles category.db made from (for example) enwikiversity-20090627-category.sql, so reports are more simpler: just put this in python code above, right before 'if __name__' ...:
import sqlite3 def querycategory(title): conn = sqlite3.connect('category.db') c = conn.cursor() t = (title,) c.execute('select cat_title from category where cat_title like "%%%s%%" ;' % t) res = [row[0] for row in c] conn.commit() c.close() return res def simplereports(title): res = querycategory(title) j = 0 for r in res: g = r.replace('_',' ') print g title= g.encode('utf8') filename = 'reps%04d.tex' % j writeres(title,'','',filename) j = j+1 return j
Similary, add this to tex code
\startluacode function listtitles(title) require("python") pg = python.globals() wikiversity = python.import("wikidbxml_queryTxn") r = wikiversity.querycategory(title) local j = 0 local res = r[j] or {} while res do local d = string.format("\%s\\par",string.gsub(tostring(res),'_',' ')) tex.sprint(tex.ctxcatcodes,d) j = j+1 res = r[j] end end \stopluacode \startluacode function simplereports(title) require("python") pg = python.globals() wikiversity = python.import("wikidbxml_queryTxn") r = wikiversity.simplereports(title) local j = tonumber(r) for v = 0,j-1 do local d = string.format("\\input reps\%04d ",v) tex.sprint(tex.ctxcatcodes,d) end print( j ) end \stopluacode
and test it with
\starttext {\bfb Query for 'geometr':} \ctxlua{listtitles("geometr")}% \ctxlua{simplereports("geometr")}% \stoptext
(query results are stored in reps0001.tex ,reps0002.tex ,..and so on.)
