text postscript unicode converter ansi-escape-codes

u2ps's Introduction

About
~~~~~
u2ps is text to postscript converter similar to a2ps,
with emphasis on Unicode support.

Key features:

* utf8 support implemented (mostly) in PostScript
* clean, readable and reasonably small output files
* font subset embedding for Type 1 and Type 42 (TTF) fonts
* ANSI control sequences support (color and font variants)

Things missing at present:

- proper combining mark positioning
- reordering and ligatures
- bidi support

The tool should be usable on any reasonably sane system with
Ghostscript installed.

As long as the input does not stray too far from common left-to-right
scripts and usable fonts are available, u2ps should work well.

Current version is probably the last one using mostly-postscript
mostly-font-agnostic approach; check TODO for further development ideas.


Installation
~~~~~~~~~~~~
Common C library, make and cc are needed to build u2ps.
Font reduction needs ghostscript at runtime.

	./configure --prefix=...
	make
	make install

Unless told otherwise, u2ps defaults to FreeMono font.
Make sure to have it installed.

For hacking/debugging, run "./configure devel" instead, the resulting
executable will work right from the source directory.


Documentation
~~~~~~~~~~~~~
See man page and text files in doc/ directory.


Sample usage
~~~~~~~~~~~~
The files in text/ directory may be used as a showcase for u2ps features.
Assuming u2ps is built in devel mode (./configure devel), run

    ./u2ps text/ansi.txt
    ./u2ps text/alph.txt
    ./u2ps text/utf8.txt
    ./u2ps -2 -f FreeMono -f Kochi -f Tlwg text/alph.txt
    ./u2ps -2 -f FreeMono -f Kochi -f Tlwg text/utf8.txt

The last two commands assume Kochi-Mincho (http://en.osdn.jp/projects/efont/)
and Tlwg (http://linux.thai.net/projects/fonts-tlwg) fonts are installed
in the system and Ghostscript knows where to find them.

Sample usage with individual font setting:

    ./u2ps -2 -f FreeMono -fC:SawarabiGothic-Medium text/alph.txt

This works for fonts not known to u2ps.


Github note
~~~~~~~~~~~
This is a modernized version of my old project from Berlios,
now rewritten in C, with lots of incompatible changes.

Check perl branch for the original code if you need it.

u2ps's Issues

if -W is the first option: Unknown option -W

$ u2ps -W -H -P letter --margins -72 N010.txt
Unknown option -W

-M and --margins seem to have no effect

-M and --margins seem to have no effect on the output.
I tried both positive numbers and negative numbers.
I tried single numbers, a pair of numbers, and four numbers.

Problems with tests

Hello,

I was trying to make a port of u2ps, and ran into some problems with tests:

The *.c tests seem to be straightforward enough -- just {,g}make
them and execute.
I don't quite understand how the *.ps tests are supposed to work.
Do I need to invoke gs with some specific arguments, or
environment to run these?
The *.sh tests seem to be failing for me, but that's probably due to
the way gs is compiled on my system. I did, however, notice a bashism
on the line 10 of px_reduce_rgl.sh: ">&/dev/null". Would you consider
instead making it ">/dev/null 2>&1"?

Would you please consider writing a bit of documentation for the tests
(like a few comments should be enough), and writing a make target to
run them automatically?

how do I manage word splitting at the end of the line?

First of all, thank you for developing this tool.
I have a text file which has long lines. I use -w switch to split long line into new line, however sometimes it splits a word incorrectly.
How do I disable word splitting in u2ps?
Regards.

u2ps issuing a message "DEBUG: FC_WEIGHT didn't match"

After building and installing, as a simple test:

$ u2ps README
DEBUG: FC_WEIGHT didn't match
$

Was expecting PostScript on stdout, but that's all there is.
I added the -v flag and got:

$ u2ps -v README
Terminal area 481x732pt, final font size 1000cpt, 80 cols 73 rows
Font R aspect 600cpt xscale 1000mil name FreeMono
Font I aspect 600cpt xscale 1000mil name FreeMonoOblique
Font B aspect 600cpt xscale 1000mil name FreeMonoBold
Font O aspect 600cpt xscale 1000mil name FreeMonoBoldOblique
DEBUG: FC_WEIGHT didn't match

Is there a debug flag I should turn on to show what's being executed?

compiling on cygwin64

Hello!

I just tried it, and I found I had to add the -std=c99 option for the compiler to work. I also found that the header definition of the struct runopts.stdout conflicted with other definitions of stdout elsewhere; I fixed the issue by renaming it to runopts.stdouts everywhere it appeared.
