#### \phi versus \varphi

Greetings -

My anal compulsive editors (who soend their off-time wondering if anal
compulsive should be hyphenated or not - I digress...) have asked me to
consider a global change of \phi to \varphi. While this is doable
(although it amounts to changing approximately 1100 instances of \phi
over 800+ pages of the book), I'm trying to see if there is a compelling
argument one way or the other beyond aesthetics (which in this instance
don't lead me one way or the other).

In said document, phi (of whatever glyph) represents a parameter (in big
multinomial models and likelihoods and such). My impression had been
that \phi was more appropriately used for such things, and that \varphi
really was the lower-case of the Greek letter phi (in other words, if I
was writing *text* in Greek, I'd use \varphi). But this is math (which
is Greek to some. Again I digress...), so I'd thought \phi.

Any thoughts? I've resisted using my 'get stuffed' email macro to the
editor until I'd thought about it a bit - and got some more learned (or
at least objective) opinions.

Ta much...

I think if editors asked you to change all \phi (this glyph) to
\varphi (that glyph) you should agree and change them :-)
But do this in "minimal" way:
\let\oldphi\phi
\let\phi\varphi

my recollection is that none of my (modern) greek textbooks use
\varphi, but that my teacher's handwriting (and certainly mine) do.  i
don't have any textbooks here, so can't comment further until i've
taken a look at them.  if appropriate, i could dig out the books this
evening.  (of course, there's no maths in any of those books.)

apostoulos syropoulos (the author of several packages on ctan) is a
mathematician, iirc, and might be able to provide a more nearly

but as vladimir's pointed out, the change to the sources would surely
take less than a minute anyway so you can delay...

No, don't change 1100 instances.  That is the Microsoft Word way to do
it.  Instead, use the TeX way.  Here: I looked at a document I am
working on.  Near the top I have these lines...

\renewcommand{\phi}{\varphi}
\renewcommand{\epsilon}{\varepsilon}
\renewcommand{\emptyset}{\varnothing}

I guess only one of them is what you want, but others can be done, too!

Save your energy for important arguments.  In this instance, just do
what the editor wants.

I recommend to use \let. In case if you want glyph that (old) \phi
produce how you can get it?

\let\oldphi\phi
\let\phi\varphi

Now \phi prints the same glyph as \varphi while \oldphi gives you the
glyph which \phi prints by default.

Actually I input following lines into my document when I need \phi
prints the same glyph as \varphi (as well as epsilon):

\makeatletter
\let\old@phi\phi
\let\old@varphi\varphi
\let\old@epsilon\epsilon
\let\old@varepsilon\varepsilon
\let\phi\old@varphi
\let\varphi\old@phi
\let\epsilon\old@varepsilon
\let\varepsilon\old@epsilon
\makeatother

Don't bother that @ do here these lines just swap \phi<->\varphi,
\epsilon<->\varepsilon.

By the way, if one editor thinks that (old) \phi should be as (old)
\varphi then the lines does job. If another editor thinks
that (old) \varphi should be as (old) \phi just comment lines.

I think \varphi  looks better most of the time (partly because it seems
to come up more often in handwriting). The \phi might in fact be
confused with \emptyset by a casual reader. For the big letter there
is always \Phi available.

Thanks for all the good suggestions. I'd forgotten about the possibility
of doing something like

\renewcommand{\phi}{\varphi}

would save the search and replace time (although on a good machine, not
too odious...).

Cheers...

I tend to agree (about the aesthetic merits of \varphi), and understand
though. ;-)

As for cap \Phi, I thought about that. If (i) the vast majority of the
other parameters weren't lower case, and (ii) if I was using cap symbols
for matrices and vectors (by and large), I'd consider it.

Thanks again.

I see \phi and \varphi in roughly equal numbers in math
journal/monographs/textbooks. The result of \phi (in CM fonts
anyway) somehow looks more like a symbol than a variable,
so I personally prefer \varphi. Also, a lot of beople (incorectly,
IMO)
use \phi for the empty set.

Since \varphi takes twice as long to type, my articles all begin with

\let\oldphi\phi % optional
\let\phi\varphi

If I had to deal with really anal retentive editors, I'd run a
search-and-replace operation: just in case they were so
AR as to require the _source_ be changed. The total time
to change 1100 instances? No more than it takes to type
the above two lines. Really.

A lot of books in my field (electrical machines) use both symbols for
different values. While \varphi often represents an angle, \phi
represents a factor.

So, if your editor tells you what to do you'll prob. have no other
chance. But you both should look what's convenient in your field...

BTW, what does 'var' stand for in \varphi?

Not really. Either do a global search and replace with your text editor,
or simply switch the meaning of \phi and \varphi in the limbo. Each takes
only a minute.

Check what the conventions in your field are, in my case the IUPAC "Green
Book" (Quantities, Units and Symbols in Physical Chemistry,
http://old.iupac.org/publications/books/gbook/index.html) is the
autoritative source.

no, an uppercase of \phi is \Phi

Index on TEXT versus CHAR(32)... fast exact TEXT matching
I have a table that stores TEXT information. I need query this table to find *exact* matches to the TEXT... no regular expressions, no LIKE queries, etc. The TEXT could be from 1 to 10000+ characters in length, quite variable. If it matters, the TEXT may contain UNICODE characters... Example: CREATE TABLE a (id SERIAL, thetext TEXT); SELECT id FROM a WHERE thetext='Some other text'; One way I thought to optimize this process would be to store an MD5 hash of the "thetext" column and query on that: CREATE TABLE a (id SERIAL, thetext TEXT, thetext_md5 CHAR(...

setting TeX text variable depending on keyval-generated param? (low-level TeX question)
I am using keyval to set a "scaled" parameter and am having trouble getting the right behavior, which is: If I \usepackage{package} with no [scaled] option, I want to set a variable to a compile-time-specified default, say "s*[a.b]". If I \usepackage[scaled]{package}, same thing. And if I \usepackage[scaled=x.y], I want to set the variable to "s*[x.y]". (This is for font scaling, and I've used as my model the Helvetica scaled parameter.) The variable name (for the purposes of this conversation) is pnm@scaled. What I have that's not working correctly is: \expandafter\ifx\csname pmn@scaled\endcsname\relax \let\pmn@scaled\@empty \else \edef\pmn@scaled{s*[1.2]}% \fi I think what this says is "if pnm@scaled is not defined (case 1), leave it empty, otherwise set it to "s[1.2]". But the else clause is not working correctly, and I don't know how to differentiate between "defined by keyval but with no value" and "defined by keyval but with a value". Also I'm pretty sure I don't really know the difference between \let and \edef. Any help gratefully appreciated. Thanks.

I see other posts where some say fields that will hold a number with leading zeros should be stored as text instead of numbers.

Storing as a number still allows for formatting when displaying the number, correct? I am creating a table and would like opinions regarding this please.

For this I wrote a awk script to convert double quotes to the correct type in TeX, as in #!/usr/bin/awk -f # DQ2TQ : Converts double qoutes in plaint text file to TeX format # USAGE # dq2tq filename > newfilename BEGIN { count = 0 } /"/ { for (i=1; i<=NF; i++) {if (count % 2 == 0) {sub(/"/,"`",$i);count++} else {sub(/"/,"''",$i);count++}} } { print } However this does not seem to work right. Given the following input : " " " " &... Surrounding text with text I was wondering if it was possible to surround a text body with text like so: +--------------+ |ABCDEFGHIJKLM | |H N| |A Main Body O| |L Text goes P| |B here Q| |-=+_ZYXWVUTSR | | | | | | | | | +--------------+ This seems far-fetched, but just curious. I suppose that I could just move stuff around by hand in the GIMP later on, but there's probably a {better,more {extensible,clean}} way of doing it from (La)TeX. -FreeSmith ptjm@interlog.com (Patrick TJ McPhee) wrote in message news:<bffbhe$per$1@news.eusc.inter... equal? versus eql? versus == versus === verus <=> I recently found myself explaining to a friend how Ruby's various comparison operators work. In the process, I tried to find some decent documentation on why Ruby has so many different ways to test for equality, how they differ and how they should be implemented and used.

I've got the problem that when I type LaTeX-orders like V_{DS} or$V_{DS} $a.s.o. as strings in static text, this orders are not converted. How can I manage, that my LaTeX-orders are interpreted!

All Consider the string involving greek letters to appear in a plot title made with the command: SetaEL='\fontsize{14}{\eta}\fontsize{10}EL\fontsize{10}=' when used in a title argument, the string SetaEL plots like: etaEL= except that eta will be the actual greek letter of course. This works! BUT THE COLOR ID DEFAULT IS BLACK. THE QUESTION: How to change my SetaEL command useing TeX syntax, so it is say red? Thanks in advance....tony Could you be a little more specific?

Mac versus Windows CS3 regarding text Hi group I'm a recent convert to Apple, I just bought a new IMac, and installed Photoshop CS3. I'm having a hard time working with text (it's fuzzy)and after looking at newsgroup searches it seems as if the "fuzzy" text I'm getting is something that I need to learn how to control with a lengthy education. The problem is I've been working with photoshop on windows for ten years and this is not an issue. I even went on the old Win verson of Cs2 and the text still looks great without doing a thing. Can anyone help me with this issue?

Convert TeX to normal text (stripping macros) Hi all, Does anyone know a good way to strip a TeX file from its macros in order to run grammar checking from LangauageTool on it? Please also see this bug report for Language Tool: https://sourceforge.net/tracker/index.php?func=detail&aid=2880449&group_id=110216&atid=655717 A Java implementation would be preferred since Language Tool is in Java so it runs platform independently.

If I try to set the 'string' property for the GUI object using '\mu' this just displays '\mu'.
