udl - Convert EOL formats freely between MS-DOS (CR/LF), Unix/Amiga (LF),
|
|
and Apple (CR).

|
|
=============================================================================
|
|
|
|
Udl converts text files between the various end-of-line conventions, i.e.
|
|
CR, LF, and CR/LF, used by the Apple IIgs, MS-DOS, Amiga, and Unix.
|
|
After conversion, the original file is replaced with the converted file.
|
|
Udl is known to run with ORCA/Shell 2.x, GNO/ME 2.x, and Unix.
|
|
|
|
Not only is udl faster and simpler than tr(1), but it saves a step in
|
|
the conversion process by automatically replacing the original file
|
|
after the conversion completes. Thus:
|
|
udl file
|
|
replaces the longer sequence of
|
|
tr '\012' '\015' < file > file.temp
|
|
mv file.temp file
|
|
Because it replaces the original file, udl makes every effort to ensure
|
|
that the conversion process cannot corrupt the original. The translation
|
|
process uses a temporary file and replaces the original only after the
|
|
translation has completed. In case of a machine crash or power-down, the
|
|
original file remains intact, unless the machine dies at precisely the
|
|
instant the update occurs. This problem exists for a manual file
|
|
replacement, as in:
|
|
mv file.temp file
|
|
so the risk is no greater.
|
|
|
|
=========
|
|
Compiling:
|
|
=========
|
|
|
|
Three makefiles are included:
|
|
Makefile.gs For use on the Apple IIgs running GNO
|
|
Makefile.unx For use with Unix systems
|
|
Makefile.msd For use with MS-DOS systems (djgpp)
|
|
|
|
Although udl on the IIgs can be run from either GNO or ORCA shells,
|
|
it cannot be built with the standard ORCA installation due to a lack
|
|
of additional libraries.
|
|
|
|
The IIgs distribution should contain a binary of udl, including a
|
|
resource fork. Therefore, you should be able to skip straight to the
|
|
section on installation. For those who must know, however, building the
|
|
binaries under GNO should just be a matter of typing 'dmake -f Makefile.gs'.
|
|
|
|
If you are compiling on Unix operating systems that have been previously
|
|
tested, you should be able to just type 'make -f Makefile.unx'. This
|
|
will select the appropriate DEFINES for your system. For an explanation
|
|
the various DEFINES, see the section below on "DEFINES Definitions".
|
|
|
|
Note that compilation of udl _requires_ an ANSI C compiler.
|
|
|
|
If you are compiling to a new system, add in another set of defines
|
|
and let us know about them.
|
|
|
|
Note that udlunix.c and udlgs.c assume that getopt() is declared in
|
|
<unistd.h> and that the function strdup() exists in <string.h>. You
|
|
might have to change these includes if that's not the case. Ensure you
|
|
use cpp conditional compilations to match your platform (and to avoid
|
|
breaking the code for other platforms).
|
|
|
|
============
|
|
Installation
|
|
============
|
|
|
|
Apple IIgs with GNO
|
|
^^^^^^^^^^^^^^^^^^^
|
|
Type 'dmake install -f Makefile.gs'. By default this copies the binary
|
|
into "/usr/local/bin" and the man page into "/usr/local/man/man1". (You
|
|
_are_ using version 3.x of 'man', are you not? *blatant plug*) If you
|
|
don't like these locations, either modify the BINDIR and MANDIR
|
|
macros in the makefile or install the files by hand.
|
|
|
|
If you have describe(1) installed, you can update the udl(1) entry
|
|
with the file "describe.udl". See the descu(8) and descc(8) man pages
|
|
for details.
|
|
|
|
Apple IIgs with Orca/Shell
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
Copy the following files to their respective destinations:
|
|
|
|
udl to 17
|
|
help/udl to 17/help
|
|
|
|
Unix systems
|
|
^^^^^^^^^^^^
|
|
Type 'make -f Makefile.unx install'. By default the binary will
|
|
go into /usr/local/bin and the man page into /usr/local/man/man1.
|
|
This assumes root access. If this does not match your plans and/or
|
|
access permissions, either copy the files by hand or change the
|
|
BINDIR, MANDIR, and OWNER_GROUP macros in the makefile.
|
|
|
|
===================
|
|
DEFINES Definitions
|
|
===================
|
|
|
|
If you have problems compiling or are porting udl to a new operating
|
|
system, define the following macros in the makefile as necessary.
|
|
They should be used as the value of $(DEFINES_$(OS)) where $(OS) is
|
|
your operating system as returned by `uname -sr | tr ' ' '_'`.
|
|
|
|
HAS_ATEXIT if your system has atexit()
|
|
|
|
_POSIX_C_SOURCE and _POSIX_SOURCE if your compiler is Posix compliant
|
|
|
|
READDIR_RETURNS_DOT if your direct readdir() function will return
|
|
entries for "." and "..". SunOS 4.x and 5.x (Solaris) are known to
|
|
do this.
|
|
|
|
BROKEN_REALLOC if your realloc() doesn't behave like malloc() when
|
|
passed a NULL pointer as the first argument.
|
|
|
|
BROKEN_DIRENT_STRUCT if you find that the first two letters of
|
|
filenames obtained during directory recursion (as shown when the
|
|
"-v" flag is used) seem to be missing. Some installations of
|
|
Solaris are known to do this.
|
|
|
|
GNO if you are compiling on the IIgs. This will allow for both
|
|
':' and '/' as pathname separators.
|
|
|
|
OVERFLOW_CHECK Udl uses one recursive subroutine. Define this if
|
|
you want to check for stack overflows for this routine (independent
|
|
of any compiler flags). Strongly recommended.
|
|
|
|
CHECK_STACK if you want stack usage to be displayed (IIgs only).
|
|
You will also have to specify -l/usr/lib/stack in LDFLAGS.
|
|
|
|
The following are the DEFINES values for tested operating systems:
|
|
|
|

Notes
|
|
=====
|
|
|
|
If the machine crashes before udl has replaced the original file with
|
|
the converted file, the temporary file needs to be manually deleted.
|
|
The temporary file resides in the same directory as the source file
|
|
and has a name of the form:
|
|
UDLTMPXX
|
|
where XX is replaced by AA, AB and so on.
