ini -> C -> lua -> context -> pdf

ini -> C -> lua -> context -> pdf

[Peter Münster]

Hello,

I have to convert an "ini"-file to pdf. On the one hand, it's easy for me
to do most things in C, on the other hand, I would like to enlarge my
experience with lua and ConTeXt.

So here my question to the experts: what languages would you use for the
different tasks?

In fact, I believe lua could do a good job for some tasks, but I'm not
really sure.

Here the details:

Example "ini"-file with 2 entries (the real file has about 200 entries):

[temp_room]
comment = the room temperature in °C
description = This value must be sent at least once per 15 minutes, \
			but only if a local sensor is connected to the device.
size = 16
channel = master
fb = RTS
dpt = 2.009
dir = o

[power]
comment = the actual power available in %
description = This value is only used to calculate the energy \
			consumption.
size = 8
channel = slave
fb = HVA
dpt = 4.307
dir = i


The tasks:
- put theses entries into a structured table (easy to do in C and the
  iniparser library http://ndevilla.free.fr/iniparser/ but it could be nice
  to do it in lua)
- sorting (several PDF-documents with different sorting: by name, size,
  channel or other values)
- filtering, for example _ must be converted to \_ and % to \% (same
  question: C, lua or ConTeXt)
- formatting with nice layout (certainly with ConTeXt)

For example, the first entry could become:

1.) temp_room, the room temperature in °C
-----------------------------------------
______________________________________________________________________
|   Master  |   RTS   |  Output with datapoint type 2.009 (16 bits)  |
|___________|_________|______________________________________________|

This value must be sent at least once per 15 minutes, but only if a
local sensor is connected to the device.


(Until now, I've coded just one line of lua-code in my life...)

Perhaps, with your help, the subject line could become:
ini -> MKIV -> pdf

Thanks in advance for any hints and encouragements!
Cheers, Peter

this kind of parsing is rather trival in lua

sorting is also easy

depends, if the font has _ no conversion is needed (otf fonts have this)

ini parsing ... look into string.find; loop over the lines and triugger 
on [...] and ...=...

Since I'm using MKIV, I think the default font should be the lm otf
version, isn't it?
What setup is needed, to make "_" behave like a real underscore?

Thanks, I've spent some minutes today looking into the string, io and table
libraries, and indeed lua looks very powerful.
Perhaps, this will result in a module.

Cheers, Peter

\nonknuthmode (and there is \donknuthmode to get the default behaviour)
