The second biggest trap is not making your entire program runnable under \f(CW\*(C`use strict\*(C'\fR. The third biggest trap is not reading the list of changes in this version of Perl; see perldelta. .SS "Awk Traps" .IX Subsection "Awk Traps" Accustomed \fBawk\fR users should take special note of the following: .IP "\(bu" 4 A Perl program executes only once, not once for each input line. You can do an implicit loop with \f(CW\*(C`\-n\*(C'\fR or \f(CW\*(C`\-p\*(C'\fR. .IP "\(bu" 4 The English module, loaded via .Sp .Vb 1 \& use English; .Ve .Sp allows you to refer to special variables (like \f(CW$/\fR) with names (like \&\f(CW$RS\fR), as though they were in \fBawk\fR; see perlvar for details. .IP "\(bu" 4 Semicolons are required after all simple statements in Perl (except at the end of a block). Newline is not a statement delimiter. .IP "\(bu" 4 Curly brackets are required on \f(CW\*(C`if\*(C'\fRs and \f(CW\*(C`while\*(C'\fRs. .IP "\(bu" 4 Variables begin with \*(L"$\*(R", \*(L"@\*(R" or \*(L"%\*(R" in Perl. .IP "\(bu" 4 Arrays index from 0. Likewise string positions in \fBsubstr()\fR and \&\fBindex()\fR. .IP "\(bu" 4 You have to decide whether your array has numeric or string indices. .IP "\(bu" 4 Hash values do not spring into existence upon mere reference. .IP "\(bu" 4 You have to decide whether you want to use string or numeric comparisons. .IP "\(bu" 4 Reading an input line does not split it for you. You get to split it to an array yourself. And the \fBsplit()\fR operator has different arguments than \fBawk\fR's. .IP "\(bu" 4 The current input line is normally in \f(CW$_\fR, not \f(CW$0\fR. It generally does not have the newline stripped. ($0 is the name of the program executed.) See perlvar. .IP "\(bu" 4 $<\fIdigit\fR> does not refer to fields\*(--it refers to substrings matched by the last match pattern. .IP "\(bu" 4 The \fBprint()\fR statement does not add field and record separators unless you set \f(CW$,\fR and \f(CW\*(C`$\e\*(C'\fR. You can set \f(CW$OFS\fR and \f(CW$ORS\fR if you're using the English module. .IP "\(bu" 4 You must open your files before you print to them. .IP "\(bu" 4 The range operator is \*(L"..\*(R", not comma. The comma operator works as in C. .IP "\(bu" 4 The match operator is \*(L"=~\*(R", not \*(L"~\*(R". (\*(L"~\*(R" is the one's complement operator, as in C.) .IP "\(bu" 4 The exponentiation operator is \*(L"**\*(R", not \*(L"^\*(R". \*(L"^\*(R" is the \s-1XOR\s0 operator, as in C. (You know, one could get the feeling that \fBawk\fR is basically incompatible with C.) .IP "\(bu" 4 The concatenation operator is \*(L".\*(R", not the null string. (Using the null string would render \f(CW\*(C`/pat/ /pat/\*(C'\fR unparsable, because the third slash would be interpreted as a division operator\*(--the tokenizer is in fact slightly context sensitive for operators like \*(L"/\*(R", \*(L"?\*(R", and \*(L">\*(R". And in fact, \*(L".\*(R" itself can be the beginning of a number.) .IP "\(bu" 4 The \f(CW\*(C`next\*(C'\fR, \f(CW\*(C`exit\*(C'\fR, and \f(CW\*(C`continue\*(C'\fR keywords work differently. .IP "\(bu" 4 The following variables work differently: .Sp .Vb 10 \& Awk Perl \& ARGC scalar @ARGV (compare with $#ARGV) \& ARGV[0] $0 \& FILENAME $ARGV \& FNR $. \- something \& FS (whatever you like) \& NF $#Fld, or some such \& NR $. \& OFMT $# \& OFS $, \& ORS $\e \& RLENGTH length($&) \& RS $/ \& RSTART length($\`) \& SUBSEP $; .Ve .IP "\(bu" 4 You cannot set \f(CW$RS\fR to a pattern, only a string. .IP "\(bu" 4 When in doubt, run the \fBawk\fR construct through \fBa2p\fR and see what it gives you. .SS "C/\*(C+ Traps" .IX Subsection "C/ Traps" Cerebral C and \*(C+ programmers should take note of the following: .IP "\(bu" 4 Curly brackets are required on \f(CW\*(C`if\*(C'\fR's and \f(CW\*(C`while\*(C'\fR's. .IP "\(bu" 4 You must use \f(CW\*(C`elsif\*(C'\fR rather than \f(CW\*(C`else if\*(C'\fR. .IP "\(bu" 4 The \f(CW\*(C`break\*(C'\fR and \f(CW\*(C`continue\*(C'\fR keywords from C become in Perl \f(CW\*(C`last\*(C'\fR and \f(CW\*(C`next\*(C'\fR, respectively. Unlike in C, these do \fInot\fR work within a \&\f(CW\*(C`do { } while\*(C'\fR construct. See \*(L"Loop Control\*(R" in perlsyn. .IP "\(bu" 4 The switch statement is called \f(CW\*(C`given\*(C'\fR/\f(CW\*(C`when\*(C'\fR and only available in perl 5.10 or newer. See \*(L"Switch Statements\*(R" in perlsyn. .IP "\(bu" 4 Variables begin with \*(L"$\*(R", \*(L"@\*(R" or \*(L"%\*(R" in Perl. .IP "\(bu" 4 Comments begin with \*(L"#\*(R", not \*(L"/*\*(R" or \*(L"//\*(R". Perl may interpret C/\*(C+ comments as division operators, unterminated regular expressions or the defined-or operator. .IP "\(bu" 4 You can't take the address of anything, although a similar operator in Perl is the backslash, which creates a reference. .IP "\(bu" 4 \&\f(CW\*(C`ARGV\*(C'\fR must be capitalized. \f(CW$ARGV[0]\fR is C's \f(CW\*(C`argv[1]\*(C'\fR, and \f(CW\*(C`argv[0]\*(C'\fR ends up in \f(CW$0\fR. .IP "\(bu" 4 System calls such as \fBlink()\fR, \fBunlink()\fR, \fBrename()\fR, etc. return nonzero for success, not 0. (\fBsystem()\fR, however, returns zero for success.) .IP "\(bu" 4 Signal handlers deal with signal names, not numbers. Use \f(CW\*(C`kill \-l\*(C'\fR to find their names on your system. .SS "JavaScript Traps" .IX Subsection "JavaScript Traps" Judicious JavaScript programmers should take note of the following: .IP "\(bu" 4 In Perl, binary \f(CW\*(C`+\*(C'\fR is always addition. \f(CW\*(C`$string1 + $string2\*(C'\fR converts both strings to numbers and then adds them. To concatenate two strings, use the \f(CW\*(C`.\*(C'\fR operator. .IP "\(bu" 4 The \f(CW\*(C`+\*(C'\fR unary operator doesn't do anything in Perl. It exists to avoid syntactic ambiguities. .IP "\(bu" 4 Unlike \f(CW\*(C`for...in\*(C'\fR, Perl's \f(CW\*(C`for\*(C'\fR (also spelled \f(CW\*(C`foreach\*(C'\fR) does not allow the left-hand side to be an arbitrary expression. It must be a variable: .Sp .Vb 3 \& for my $variable (keys %hash) { \& ... \& } .Ve .Sp Furthermore, don't forget the \f(CW\*(C`keys\*(C'\fR in there, as \&\f(CW\*(C`foreach my $kv (%hash) {}\*(C'\fR iterates over the keys and values, and is generally not useful ($kv would be a key, then a value, and so on). .IP "\(bu" 4 To iterate over the indices of an array, use \f(CW\*(C`foreach my $i (0 .. $#array) {}\*(C'\fR. \f(CW\*(C`foreach my $v (@array) {}\*(C'\fR iterates over the values. .IP "\(bu" 4 Perl requires braces following \f(CW\*(C`if\*(C'\fR, \f(CW\*(C`while\*(C'\fR, \f(CW\*(C`foreach\*(C'\fR, etc. .IP "\(bu" 4 In Perl, \f(CW\*(C`else if\*(C'\fR is spelled \f(CW\*(C`elsif\*(C'\fR. .IP "\(bu" 4 \&\f(CW\*(C`? :\*(C'\fR has higher precedence than assignment. In JavaScript, one can write: .Sp .Vb 1 \& condition ? do_something() : variable = 3 .Ve .Sp and the variable is only assigned if the condition is false. In Perl, you need parentheses: .Sp .Vb 1 \& $condition ? do_something() : ($variable = 3); .Ve .Sp Or just use \f(CW\*(C`if\*(C'\fR. .IP "\(bu" 4 Perl requires semicolons to separate statements. .IP "\(bu" 4 Variables declared with \f(CW\*(C`my\*(C'\fR only affect code \fIafter\fR the declaration. You cannot write \f(CW\*(C`$x = 1; my $x;\*(C'\fR and expect the first assignment to affect the same variable. It will instead assign to an \f(CW$x\fR declared previously in an outer scope, or to a global variable. .Sp Note also that the variable is not visible until the following \&\fIstatement\fR. This means that in \f(CW\*(C`my $x = 1 + $x\*(C'\fR the second \f(CW$x\fR refers to one declared previously. .IP "\(bu" 4 \&\f(CW\*(C`my\*(C'\fR variables are scoped to the current block, not to the current function. If you write \f(CW\*(C`{my $x;} $x;\*(C'\fR, the second \f(CW$x\fR does not refer to the one declared inside the block. .IP "\(bu" 4 An object's members cannot be made accessible as variables. The closest Perl equivalent to \f(CW\*(C`with(object) { method() }\*(C'\fR is \f(CW\*(C`for\*(C'\fR, which can alias \&\f(CW$_\fR to the object: .Sp .Vb 3 \& for ($object) { \& $_\->method; \& } .Ve .IP "\(bu" 4 The object or class on which a method is called is passed as one of the method's arguments, not as a separate \f(CW\*(C`this\*(C'\fR value. .SS "Sed Traps" .IX Subsection "Sed Traps" Seasoned \fBsed\fR programmers should take note of the following: .IP "\(bu" 4 A Perl program executes only once, not once for each input line. You can do an implicit loop with \f(CW\*(C`\-n\*(C'\fR or \f(CW\*(C`\-p\*(C'\fR. .IP "\(bu" 4 Backreferences in substitutions use \*(L"$\*(R" rather than \*(L"\e\*(R". .IP "\(bu" 4 The pattern matching metacharacters \*(L"(\*(R", \*(L")\*(R", and \*(L"|\*(R" do not have backslashes in front. .IP "\(bu" 4 The range operator is \f(CW\*(C`...\*(C'\fR, rather than comma. .SS "Shell Traps" .IX Subsection "Shell Traps" Sharp shell programmers should take note of the following: .IP "\(bu" 4 The backtick operator does variable interpolation without regard to the presence of single quotes in the command. .IP "\(bu" 4 The backtick operator does no translation of the return value, unlike \fBcsh\fR. .IP "\(bu" 4 Shells (especially \fBcsh\fR) do several levels of substitution on each command line. Perl does substitution in only certain constructs such as double quotes, backticks, angle brackets, and search patterns. .IP "\(bu" 4 Shells interpret scripts a little bit at a time. Perl compiles the entire program before executing it (except for \f(CW\*(C`BEGIN\*(C'\fR blocks, which execute at compile time). .IP "\(bu" 4 The arguments are available via \f(CW@ARGV\fR, not \f(CW$1\fR, \f(CW$2\fR, etc. .IP "\(bu" 4 The environment is not automatically made available as separate scalar variables. .IP "\(bu" 4 The shell's \f(CW\*(C`test\*(C'\fR uses \*(L"=\*(R", \*(L"!=\*(R", \*(L"<\*(R" etc for string comparisons and \*(L"\-eq\*(R", \&\*(L"\-ne\*(R", \*(L"\-lt\*(R" etc for numeric comparisons. This is the reverse of Perl, which uses \f(CW\*(C`eq\*(C'\fR, \f(CW\*(C`ne\*(C'\fR, \f(CW\*(C`lt\*(C'\fR for string comparisons, and \f(CW\*(C`==\*(C'\fR, \f(CW\*(C`!=\*(C'\fR \f(CW\*(C`<\*(C'\fR etc for numeric comparisons. .SS "Perl Traps" .IX Subsection "Perl Traps" Practicing Perl Programmers should take note of the following: .IP "\(bu" 4 Remember that many operations behave differently in a list context than they do in a scalar one. See perldata for details. .IP "\(bu" 4 Avoid barewords if you can, especially all lowercase ones. You can't tell by just looking at it whether a bareword is a function or a string. By using quotes on strings and parentheses on function calls, you won't ever get them confused. .IP "\(bu" 4 You cannot discern from mere inspection which builtins are unary operators (like \fBchop()\fR and \fBchdir()\fR) and which are list operators (like \fBprint()\fR and \fBunlink()\fR). (Unless prototyped, user-defined subroutines can \fBonly\fR be list operators, never unary ones.) See perlop and perlsub. .IP "\(bu" 4 People have a hard time remembering that some functions default to \f(CW$_\fR, or \f(CW@ARGV\fR, or whatever, but that others which you might expect to do not. .IP "\(bu" 4 The <\s-1FH\s0> construct is not the name of the filehandle, it is a readline operation on that handle. The data read is assigned to \f(CW$_\fR only if the file read is the sole condition in a while loop: .Sp .Vb 3 \& while (<FH>) { } \& while (defined($_ = <FH>)) { }.. \& <FH>; # data discarded! .Ve .IP "\(bu" 4 Remember not to use \f(CW\*(C`=\*(C'\fR when you need \f(CW\*(C`=~\*(C'\fR; these two constructs are quite different: .Sp .Vb 2 \& $x = /foo/; \& $x =~ /foo/; .Ve .IP "\(bu" 4 The \f(CW\*(C`do {}\*(C'\fR construct isn't a real loop that you can use loop control on. .IP "\(bu" 4 Use \f(CW\*(C`my()\*(C'\fR for local variables whenever you can get away with it (but see perlform for where you can't). Using \f(CW\*(C`local()\*(C'\fR actually gives a local value to a global variable, which leaves you open to unforeseen side-effects of dynamic scoping. .IP "\(bu" 4 If you localize an exported variable in a module, its exported value will not change. The local name becomes an alias to a new value but the external name is still an alias for the original. .PP As always, if any of these are ever officially declared as bugs, they'll be fixed and removed.
