wishes for lout

[Basile STARYNKEVITCH]

Hello All,

Greeting and a happy new 1998 year to everyone!


And again two feature wishes for Lout.

1) I think that all internal files used by lout should be overiddable
at a command option. In particular, I think that the default name
lout.li should be overriddable.

2) I would like that Lout could -at command option- parse line
numbering comments à la cpp. So Lout would recognize comment lines
starting with # at column 1 such as
#line "foo" 35
# 35 "foo"
# 35 "foo" 1

and would update its position to file "foo" line 35.

Why am I asking this?

Let's suppose I am preparing a lecture (in a technical university) on
Caml & functional programming. So I want to produce

1) transparent overhead slides (without details)

2) a report containing the lecture notes with details

from a common source.

I'm using CPP to conditionnaly process some Lout. Typical usage
in beginning of file cours.plt

  @SysInclude { fontdefs        } # font definitions
  @SysInclude { langdefs        } # language definitions
  @SysInclude { dl              } # DocumentLayout package
#ifdef SLIDES
  @SysInclude { slidesf         } # OverheadLayout extension
#else
  @SysInclude { docf }
#endif 

and later in the file

Ocaml is a wonderful langage
#ifndef SLIDES
and easy to learn
#endif 

I put the CPP source to lout into course.plt have a makefile like

all: _slides.ps _report.ps

_slides.ps : _slides.lt
        rm -f lout.li
        ln -s _slides_lout.li lout.li
        lout -a -o _slides.ps _slides.lt

_report.ps : _report.lt
        rm -f lout.li
        ln -s _report_lout.li lout.li
        lout -a -o _report.ps _report.lt

_slides:lt : course.plt
        cpp -DSLIDES course.plt > _slides.lt

_report.lt : report.plt
        cpp -DREPORT course.plt > _report.lt

clean:
        rm *.li _*

By the way, is there any easy option to make Lout conditionnally
process some stuff?
