*if_perl.txt*   For Vim version 8.2.  Last change: 2019 Dec 07

VIM REFERENCE MANUAL    by Sven Verdoolaege
					 and Matt Gerassimof

Perl and Vim				*perl* *Perl*

{only available when Vim was compiled with the |+perl| feature}

==============================================================================
1. Editing Perl files					*perl-editing*

Vim syntax highlighting supports Perl and POD files.  Vim assumes a file is
Perl code if the filename has a .pl or .pm suffix.  Vim also examines the first
line of a file, regardless of the filename suffix, to check if a file is a
Perl script (see scripts.vim in Vim's syntax directory).  Vim assumes a file
is POD text if the filename has a .POD suffix.

To use tags with Perl, you need a recent version of Exuberant ctags.  Look
here:
	http://ctags.sourceforge.net

Alternatively, you can use the Perl script pltags.pl, which is shipped with
Vim in the $VIMRUNTIME/tools directory.  This script has currently more
features than Exuberant ctags' Perl support.

==============================================================================
2. Compiling Vim with Perl interface			*perl-compiling*

To compile Vim with Perl interface, you need Perl 5.004 (or later).  Perl must
be installed before you compile Vim.  Vim's Perl interface does NOT work with
the 5.003 version that has been officially released!  It will probably work
with Perl 5.003_05 and later.

The Perl patches for Vim were made by:
	Sven Verdoolaege <skimo@breughel.ufsia.ac.be>
	Matt Gerassimof

Perl for MS-Windows (and other platforms) can be found at:
	http://www.perl.org/
The ActiveState one should work, Strawberry Perl is a good alternative.

==============================================================================
3. Using the Perl interface				*perl-using*

*:perl* *:pe*
:pe[rl] {cmd}		Execute Perl command {cmd}.  The current package
			is "main".  Simple example to test if `:perl` is
			working: >
				:perl VIM::Msg("Hello")

:pe[rl] << [trim] [{endmarker}]
{script}
{endmarker}
			Execute Perl script {script}.
			The {endmarker} after {script} must NOT be preceded by
			any white space.

This form of the |:perl| command is mainly useful for
			including perl code in vim scripts.
			Note: This command doesn't work when the Perl feature
			wasn't compiled in.  To avoid errors, see
			|script-here|.

Example vim script: >

function! WhitePearl()
	perl << EOF
		VIM::Msg("pearls are nice for necklaces");
		VIM::Msg("rubys for rings");
		VIM::Msg("pythons for bags");
		VIM::Msg("tcls????");
	EOF
	endfunction
<
To see what version of Perl you have: >
	:perl print $^V
<

*:perldo* *:perld*
:[range]perld[o] {cmd}	Execute Perl command {cmd} for each line in the
			[range], with $_ being set to the text of each line in
			turn, without a trailing <EOL>.  Setting $_ will change
			the text, but note that it is not possible to add or
			delete lines using this command.
			The default for [range] is the whole file: "1,$".

Here are some things you can try: >

:perl $a=1
  :perldo $_ = reverse($_);1
  :perl VIM::Msg("hello")
  :perl $line = $curbuf->Get(42)
<
							*E299*
Executing Perl commands in the |sandbox| is limited.  ":perldo" will not be
possible at all.  ":perl" will be evaluated in the Safe environment, if
possible.

*perl-overview*
Here is an overview of the functions that are available to Perl: >

:perl VIM::Msg("Text")		# displays a message
  :perl VIM::Msg("Wrong!", "ErrorMsg")	# displays an error message
  :perl VIM::Msg("remark", "Comment")	# displays a highlighted message
  :perl VIM::SetOption("ai")		# sets a vim option
  :perl $nbuf = VIM::Buffers()		# returns the number of buffers
  :perl @buflist = VIM::Buffers()	# returns array of all buffers
  :perl $mybuf = (VIM::Buffers('qq.c'))[0] # returns buffer object for 'qq.c'
  :perl @winlist = VIM::Windows()	# returns array of all windows
  :perl $nwin = VIM::Windows()		# returns the number of windows
  :perl ($success, $v) = VIM::Eval('&path') # $v: option 'path', $success: 1
  :perl ($success, $v) = VIM::Eval('&xyz')  # $v: '' and $success: 0
  :perl $v = VIM::Eval('expand("<cfile>")') # expands <cfile>
  :perl $curwin->SetHeight(10)		# sets the window height
  :perl @pos = $curwin->Cursor()	# returns (row, col) array
  :perl @pos = (10, 10)
  :perl $curwin->Cursor(@pos)		# sets cursor to @pos
  :perl $curwin->Cursor(10,10)		# sets cursor to row 10 col 10
  :perl $mybuf = $curwin->Buffer()	# returns the buffer object for window
  :perl $curbuf->Name()			# returns buffer name
  :perl $curbuf->Number()		# returns buffer number
  :perl $curbuf->Count()		# returns the number of lines
  :perl $l = $curbuf->Get(10)		# returns line 10
  :perl @l = $curbuf->Get(1 .. 5)	# returns lines 1 through 5
  :perl $curbuf->Delete(10)		# deletes line 10
  :perl $curbuf->Delete(10, 20)		# delete lines 10 through 20
  :perl $curbuf->Append(10, "Line")	# appends a line
  :perl $curbuf->Append(10, "Line1", "Line2", "Line3") # appends 3 lines
  :perl @l = ("L1", "L2", "L3")
  :perl $curbuf->Append(10, @l)		# appends L1, L2 and L3
  :perl $curbuf->Set(10, "Line")	# replaces line 10
  :perl $curbuf->Set(10, "Line1", "Line2")	# replaces lines 10 and 11
  :perl $curbuf->Set(10, @l)		# replaces 3 lines
<
							*perl-Msg*
VIM::Msg({msg}, {group}?)
			Displays the message {msg}.  The optional {group}
			argument specifies a highlight group for Vim to use
			for the message.

*perl-SetOption*
VIM::SetOption({arg})	Sets a vim option.  {arg} can be any argument that the
			":set" command accepts.  Note that this means that no
			spaces are allowed in the argument!  See |:set|.

*perl-Buffers*
VIM::Buffers([{bn}...])	With no arguments, returns a list of all the buffers
			in an array context or returns the number of buffers
			in a scalar context.  For a list of buffer names or
			numbers {bn}, returns a list of the buffers matching
			{bn}, using the same rules as Vim's internal
			|bufname()| function.
			WARNING: the list becomes invalid when |:bwipe| is
			used.  Using it anyway may crash Vim.

*perl-Windows*
VIM::Windows([{wn}...])	With no arguments, returns a list of all the windows
			in an array context or returns the number of windows
			in a scalar context.  For a list of window numbers
			{wn}, returns a list of the windows with those
			numbers.
			WARNING: the list becomes invalid when a window is
			closed.  Using it anyway may crash Vim.

*perl-DoCommand*
VIM::DoCommand({cmd})	Executes Ex command {cmd}.

*perl-Eval*
VIM::Eval({expr})	Evaluates {expr} and returns (success, value) in list
			context or just value in scalar context.
			success=1 indicates that val contains the value of
			{expr}; success=0 indicates a failure to evaluate
			the expression.  '@x' returns the contents of register
			x, '&x' returns the value of option x, 'x' returns the
			value of internal |variables| x, and '$x' is equivalent
			to perl's $ENV{x}.  All |functions| accessible from
			the command-line are valid for {expr}.
			A |List| is turned into a string by joining the items
			and inserting line breaks.

*perl-Blob*
VIM::Blob({expr})	Return |Blob| literal string 0zXXXX from scalar value.

*perl-SetHeight*
Window->SetHeight({height})
			Sets the Window height to {height}, within screen
			limits.

*perl-GetCursor*
Window->Cursor({row}?, {col}?)
			With no arguments, returns a (row, col) array for the
			current cursor position in the Window.  With {row} and
			{col} arguments, sets the Window's cursor position to
			{row} and {col}.  Note that {col} is numbered from 0,
			Perl-fashion, and thus is one less than the value in
			Vim's ruler.

Window->Buffer()					*perl-Buffer*
			Returns the Buffer object corresponding to the given
			Window.

*perl-Name*
Buffer->Name()		Returns the filename for the Buffer.

*perl-Number*
Buffer->Number()	Returns the number of the Buffer.

*perl-Count*
Buffer->Count()		Returns the number of lines in the Buffer.

*perl-Get*
Buffer->Get({lnum}, {lnum}?, ...)
			Returns a text string of line {lnum} in the Buffer
			for each {lnum} specified.  An array can be passed
			with a list of {lnum}'s specified.

*perl-Delete*
Buffer->Delete({lnum}, {lnum}?)
			Deletes line {lnum} in the Buffer.  With the second
			{lnum}, deletes the range of lines from the first
			{lnum} to the second {lnum}.

*perl-Append*
Buffer->Append({lnum}, {line}, {line}?, ...)
			Appends each {line} string after Buffer line {lnum}.
			The list of {line}s can be an array.

*perl-Set*
Buffer->Set({lnum}, {line}, {line}?, ...)
			Replaces one or more Buffer lines with specified
			{lines}s, starting at Buffer line {lnum}.  The list of
			{line}s can be an array.  If the arguments are
			invalid, replacement does not occur.

$main::curwin
			The current window object.

$main::curbuf
			The current buffer object.

*script-here*
When using a script language in-line, you might want to skip this when the
language isn't supported.  But this mechanism doesn't work: >
   if has('perl')
     perl << EOF
       this will NOT work!
   EOF
   endif
Instead, put the Perl/Python/Ruby/etc. command in a function and call that
function: >
    if has('perl')
      function DefPerl()
	perl << EOF
	  this works
    EOF
      endfunction
      call DefPerl()
    endif
Note that "EOF" must be at the start of the line.

==============================================================================
4. Dynamic loading					*perl-dynamic*

On MS-Windows and Unix the Perl library can be loaded dynamically.  The
|:version| output then includes |+perl/dyn|.

This means that Vim will search for the Perl DLL or shared library file only
when needed.  When you don't use the Perl interface you don't need it, thus
you can use Vim without this file.

MS-Windows ~

You can download Perl from http://www.perl.org.  The one from ActiveState was
used for building Vim.

To use the Perl interface the Perl DLL must be in your search path.
If Vim reports it cannot find the perl512.dll, make sure your $PATH includes
the directory where it is located.  The Perl installer normally does that.
In a console window type "path" to see what directories are used.  The
'perldll' option can be also used to specify the Perl DLL.

The name of the DLL must match the Perl version Vim was compiled with.
Currently the name is "perl512.dll".  That is for Perl 5.12.  To know for
sure edit "gvim.exe" and search for "perl\d*.dll\c".

Unix ~

The 'perldll' option can be used to specify the Perl shared library file
instead of DYNAMIC_PERL_DLL file what was specified at compile time.  The
version of the shared library must match the Perl version Vim was compiled
with.
