Style:
Style, an Italian offering, is the least capable of the three, and is not
really adapted for writing Arabic. It has the standard styles, and
Find/Replace, but no options for setting page width in printing. More
seriously, the word wrap does not break at the edge of the window, but at a
predefined length that seems to be calculated from a 13 or 14" monitor.
Thus, on my SE/30, I cannot see a full line, and I have to scroll
horizontally manually in order to see what I am writing. This is clearly
not acceptable. You can, however, mix styles and fonts in a document. Style
does not save in TEXT format, as the two others do, but has an XTND file,
so you can use it with MacWrite and other XNTD-programs. In version b.3,
the Open command did not work, perhaps due to a conflict with Super
Boomerang.
In handling Arabic, another problem is that you cannot set
justification; it is stuck on left-adjusted. Thus you are always writing
'backwards', as it were, and printing will also be left-adjusted. Also, I
have been unable to add anything at the end of a line. The cursor will
then, whatever I do, place the correction at the beginning of the line.
Further, the cursor moves incorrectly. The left-arrow keys moves the cursor
forward, as it should, but at the end of the line, it jumps up to the
previous, rather than down (and vice versa for the right-arrow key). I.e.,
as in Roman text.
Although Style handles Arabic text entry and editing, it is thus not
useful for Arabic; and hardly for for European languages, at least if you
don't have a 12"+ monitor.
Summary
I will not recommend Style in its current version. The two others are,
however, very useful contributions, although both have some drawbacks. Each
has a bug; Tex-Edit the incorrect placement of the cursor at the beginning
of the line; MuEdit defaulting to no word wrap when you open the program
with a document. You can live with both, however. Tex-Edit can be set to
Arabic as standard script, so you can open it and just start typing Arabic.
MuEdit has an orient right->left option that makes it apt for Arabic, and
which is saved with the document (unlike Tex-Edit's justification).
As it currently stands, I have problems choosing between them. If you
use System 6, you have to choose Tex-Edit, as MuEdit requires System 7.
Otherwise, the printing bug in Tex-Edit, if it is general and not just on
my machine, would tip the scales against it; I do not fancy being stuck
with a half-inch margin. On the other hand, the Find-Replace bug in MuEdit
is serious, but can be circumvented using Paste instead of Replace. Thus,
with the faults I have found to date, I would choose MuEdit; but both are
very useful, and to be recommended.
If you want to include Arabic in a major work, like a book, you must
still buy a commercial Arabic-compatible word processor. But for simple
things, these editors are now almost as capable as the standard word
processors; and they are free.
