Hm, looking through the choices, I am now seized with a desire to create a <<`where doc`. And maybe a <<?whatsup doc? -- tbone1, YAPS (Yet Another Perl Schlub) And remember, if he succeeds, so what. - Chick McGee	[reply]

I'm surprised that bareword came up as most unpopular. I know for a fact that there are a million and two Perl programmers that use unquoted strings when it comes to hashes and lists. This makes me wonder if perhaps using `=>` as a comma operator and unquoted hash keys are not generally considered barewords. Example follows of course. `#!perl -w use strict; my %en2fr = ( one => 'un', two => 'deux', three => 'trois' ); # yes I realize there are better ways to grab the # hash values, this is for demonstration only :) print join( ', ', $en2fr{one}, $en2fr{two}, $en2fr{three} ), $/;` [download]	[reply] [d/l] [select]

I thought of this as well, before I voted for bareword. And I thought some more. And I arrived at the conclusion that bare words that are not ambiguous in their context are not bare at all -- in fact, they bear it quite well. There you have it. The Emperor has Clothes. Cheers!

Re^2: The most annoying common way to get a string literal in Perl is... by Skeeve (Parson) on Jul 12, 2004 at 21:33 UTC
I voted for bareword too. But I don't consider `one => 'un'` as being bareword as => explicitly (AFAIK) defines the word to it's left as being quoted. OTOH I render `$en2fr{one}` as being use of a bareword which I absolutely dislike. Consider this example and tell me without testing it's output: `$umask= umask; $hash{$umask}='umask value'; $hash{'umask'}='umask text'; print $hash{umask};` [download] Is the output 'umask text'? How can you make sure it will be 'umask value'? Or is the output 'umask value'? How can you make sure it will be 'umask text'?	[reply] [d/l] [select]

is it just me, or does everyone else's editor make it real hard to distinguish ' from " (and also `)? Which font makes it easy?	[reply]

Use a monospace font, they're better for important text things like ascii-art and coding anyways. I prefer Lucida Console `-- I'm not belgian but I play one on TV.`	[reply]
Re^2: The most annoying common way to get a string literal in Perl is... by iburrell (Chaplain) on Jun 16, 2004 at 17:44 UTC
It depends more on the font you use. The X fonts made the backtick more vertical than it should be. The apostrophe (single quote) was also slightly angled. This led to the backtick and apostrophe being used as way of faking smart quotes. With newer fonts, the backtick is more angled and easier to distinguish. Try switching the font on your editor or terminal window to something else. Any of the scalable (TrueType) fonts would do it.	[reply]

Re:x2 The most annoying common way to get a string literal in Perl is... by grinder (Bishop) on Jun 17, 2004 at 20:54 UTC
Which font makes it easy? I'm quite fond of Vera Sans Mono and I like Andale Mono. Both are nice sans serif fixed-width fonts, much nicer than Courier. Vera Sans looks gorgeous, except that maybe the minus glyph is slightly too discrete. And I'm not mad about the zero glyph in Andale. It has a horizontal bar running through it, to make it easy to distinguish it from the uppercase O glyph. I bar my zeros when I put pen to paper (when writing code longhand) but I find it annoying in a screen font). But the parens and curlies are very easy to distinguish, choose your poison. But both are definite improvements on Courier and Lucida Console. - another intruder with the mooring of the heat of the Perl	[reply]

My favorite font that makes these very distinct (as well as many other characters that can be a pain to distinguish) is ProFont. Vera Sans (mentioned above) is nice too, though it doesn't looks as nice as it scales down.	[reply]

I was a lucida console fan for a long time, but my favorite has become neep. It looks very nice both small and large. I run it at 14 point (`--neep alt-medium-r-normal--14----c--iso8859-1`) at 1600x1280 and it looks great.

Mixed singles, Mixed doubles... Oh, it's the time of year again for Wimbledon :). On a serious note, what gets me are long string literals that wrap 80 columns, and string literals that contain newlines rather than "\n". The long strings should be broken down using concatenation with '.', and multi line strings should use here docs or "\n". -- I'm Not Just Another Perl Hacker	[reply]

I don't get the difference between "here doc" and 'there doc' except that one uses double quotes for the terminator and the other uses single quotes. (Is that the only difference or is there something more subtle to be aware of?)	[reply]
Re^2: The most annoying common way to get a string literal in Perl is... (the "t") by tye (Sage) on Jul 07, 2004 at 01:32 UTC
Same as the difference between 'single' and "double": one interprets and one doesn't. Though <<'there docs' are unique in Perl for never treating \ as anything other than just \. If you thought "there doc" was some official term, then perhaps you didn't notice that most of the names used aren't names you'll find often used (never in the standard docs, for example). - tye	[reply]
