All of these work in-place, that is, they modify their scalar argument. No functions are exported by default. The following export tags exist: :utf8 all functions with utf8 in their name :taint all functions with taint in their name :refcnt all functions with refcnt in their name :ok all *ok-functions. * utf8 scalar[, mode] Returns true when the given scalar is marked as utf8, false otherwise. If the optional mode argument is given, also forces the interpretation of the string to utf8 (mode true) or plain bytes (mode false). The actual (byte-) content is not changed. The return value always reflects the state before any modification is done. This function is useful when you "import" utf8-data into perl, or when some external function (e.g. storing/retrieving from a database) removes the utf8-flag. * utf8_on scalar Similar to 'utf8 scalar, 1', but additionally returns the scalar (the argument is still modified in-place). * utf8_off scalar Similar to 'utf8 scalar, 0', but additionally returns the scalar (the argument is still modified in-place). * utf8_valid scalar [Perl 5.7] Returns true if the bytes inside the scalar form a valid utf8 string, false otherwise (the check is independent of the actual encoding perl thinks the string is in). * utf8_upgrade scalar Convert the string content of the scalar in-place to its UTF8-encoded form (and also returns it). * utf8_downgrade scalar[, fail_ok=0] Attempt to convert the string content of the scalar from UTF8-encoded to ISO-8859-1. This may not be possible if the string contains characters that cannot be represented in a single byte; if this is the case, it leaves the scalar unchanged and either returns false or, if 'fail_ok' is not true (the default), croaks. * utf8_encode scalar Convert the string value of the scalar to UTF8-encoded, but then turn off the 'SvUTF8' flag so that it looks like bytes to perl again. (Might be removed in future versions). * utf8_length scalar Returns the number of characters in the string, counting wide UTF8 characters as a single character, independent of wether the scalar is marked as containing bytes or mulitbyte characters. * $old = readonly scalar[, $new] Returns whether the scalar is currently readonly, and sets or clears the readonly status if a new status is given. * readonly_on scalar Sets the readonly flag on the scalar. * readonly_off scalar Clears the readonly flag on the scalar. * unmagic scalar, type Remove the specified magic from the scalar (DANGEROUS!). * weaken scalar Weaken a reference. (See also WeakRef). * taint scalar Taint the scalar. * tainted scalar returns true when the scalar is tainted, false otherwise. * untaint scalar Remove the tainted flag from the specified scalar. * length = len scalar Returns SvLEN (scalar), that is, the actual number of bytes allocated to the string value, or 'undef', is the scalar has no string value. * scalar = grow scalar, newlen Sets the memory area used for the scalar to the given length, if the current length is less than the new value. This does not affect the contents of the scalar, but is only useful to "pre-allocate" memory space if you know the scalar will grow. The return value is the modified scalar (the scalar is modified in-place). * scalar = extend scalar, addlen=64 Reserves enough space in the scalar so that addlen bytes can be appended without reallocating it. The actual contents of the scalar will not be affected. The modified scalar will also be returned. This function is meant to make append workloads efficient - if you append a short string to a scalar many times (millions of times), then perl will have to reallocate and copy the scalar basically every time. If you instead use 'extend $scalar, length $shortstring', then Convert::Scalar will use a "size to next power of two, roughly" algorithm, so as the scalar grows, perl will have to resize and copy it less and less often. * nread = extend_read fh, scalar, addlen=64 Calls 'extend scalar, addlen' to ensure some space is available, then do the equivalent of 'sysread' to the end, to try to fill the extra space. Returns how many bytes have been read, '0' on EOF or undef> on eror, just like 'sysread'. This function is useful to implement many protocols where you read some data, see if it is enough to decode, and if not, read some more, where the naive or easy way of doing this would result in bad performance. * nread = read_all fh, scalar, length Tries to read 'length' bytes into 'scalar'. Unlike 'read' or 'sysread', it will try to read more bytes if not all bytes could be read in one go (this is often called 'xread' in C). Returns the total nunmber of bytes read (normally 'length', unless an error or EOF occured), '0' on EOF and 'undef' on errors. * nwritten = write_all fh, scalar Like 'readall', but for writes - the equivalent of the 'xwrite' function often seen in C. * refcnt scalar[, newrefcnt] Returns the current reference count of the given scalar and optionally sets it to the given reference count. * refcnt_inc scalar Increments the reference count of the given scalar inplace. * refcnt_dec scalar Decrements the reference count of the given scalar inplace. Use 'weaken' instead if you understand what this function is fore. Better yet: don't use this module in this case. * refcnt_rv scalar[, newrefcnt] Works like 'refcnt', but dereferences the given reference first. This is useful to find the reference count of arrays or hashes, which cannot be passed directly. Remember that taking a reference of some object increases it's reference count, so the reference count used by the '*_rv'-functions tend to be one higher. * refcnt_inc_rv scalar Works like 'refcnt_inc', but dereferences the given reference first. * refcnt_dec_rv scalar Works like 'refcnt_dec', but dereferences the given reference first. * ok scalar * uok scalar * rok scalar * pok scalar * nok scalar * niok scalar Calls SvOK, SvUOK, SvROK, SvPOK, SvNOK or SvNIOK on the given scalar, respectively. %prep %setup -q -n %{cpan_name}-%{version} %build %{__perl} Makefile.PL INSTALLDIRS=vendor OPTIMIZE="%{optflags}" %{__make} %{?_smp_mflags} %check %{__make} test %install %perl_make_install %perl_process_packlist %perl_gen_filelist %files -f %{name}.files %defattr(-,root,root,755) %doc Changes README %license COPYING %changelog
