Major mode for editing Perl code.
Expression and list commands understand all Perl brackets.
Tab indents for Perl code.
Comments are delimited with # ... \n.
Paragraphs are separated by blank lines only.
Delete converts tabs to spaces as it moves back.
Uses keymap `perl-mode-map', which is not currently defined.
Variables controlling indentation style:
`perl-tab-always-indent'
Non-nil means TAB in Perl mode should always indent the current line,
regardless of where in the line point is when the TAB command is used.
`perl-tab-to-comment'
Non-nil means that for lines which don't need indenting, TAB will
either delete an empty comment, indent an existing comment, move
to end-of-line, or if at end-of-line already, create a new comment.
`perl-nochange'
Lines starting with this regular expression are not auto-indented.
`perl-indent-level'
Indentation of Perl statements within surrounding block.
The surrounding block's indentation is the indentation
of the line on which the open-brace appears.
`perl-continued-statement-offset'
Extra indentation given to a substatement, such as the
then-clause of an if or body of a while.
`perl-continued-brace-offset'
Extra indentation given to a brace that starts a substatement.
This is in addition to `perl-continued-statement-offset'.
`perl-brace-offset'
Extra indentation for line if it starts with an open brace.
`perl-brace-imaginary-offset'
An open brace following other text is treated as if it were
this far to the right of the start of its line.
`perl-label-offset'
Extra indentation for line that is a label.
`perl-indent-continued-arguments'
Offset of argument lines relative to usual indentation.
Various indentation styles: K&R BSD BLK GNU LW
perl-indent-level 5 8 0 2 4
perl-continued-statement-offset 5 8 4 2 4
perl-continued-brace-offset 0 0 0 0 -4
perl-brace-offset -5 -8 0 0 0
perl-brace-imaginary-offset 0 0 4 0 0
perl-label-offset -5 -8 -2 -2 -2
Turning on Perl mode runs the normal hook `perl-mode-hook'.
