vhdl-offsets-alist

vhdl-offsets-alist is a variable defined in `vhdl-mode.el'.
Its value is shown below.

Documentation:
Association list of syntactic element symbols and indentation offsets.
As described below, each cons cell in this list has the form:

(SYNTACTIC-SYMBOL . OFFSET)

When a line is indented, `vhdl-mode' first determines the syntactic
context of the line by generating a list of symbols called syntactic
elements. This list can contain more than one syntactic element and
the global variable `vhdl-syntactic-context' contains the context list
for the line being indented. Each element in this list is actually a
cons cell of the syntactic symbol and a buffer position. This buffer
position is call the relative indent point for the line. Some
syntactic symbols may not have a relative indent point associated with
them.

After the syntactic context list for a line is generated, `vhdl-mode'
calculates the absolute indentation for the line by looking at each
syntactic element in the list. First, it compares the syntactic
element against the SYNTACTIC-SYMBOL's in `vhdl-offsets-alist'. When it
finds a match, it adds the OFFSET to the column of the relative indent
point. The sum of this calculation for each element in the syntactic
list is the absolute offset for line being indented.

If the syntactic element does not match any in the `vhdl-offsets-alist',
an error is generated if `vhdl-strict-syntax-p' is non-nil, otherwise
the element is ignored.

Actually, OFFSET can be an integer, a function, a variable, or one of
the following symbols: `+', `-', `++', or `--'. These latter
designate positive or negative multiples of `vhdl-basic-offset',
respectively: *1, *-1, *2, and *-2. If OFFSET is a function, it is
called with a single argument containing the cons of the syntactic
element symbol and the relative indent point. The function should
return an integer offset.

Here is the current list of valid syntactic element symbols:

string -- inside multi-line string
block-open -- statement block open
block-close -- statement block close
statement -- a VHDL statement
statement-cont -- a continuation of a VHDL statement
statement-block-intro -- the first line in a new statement block
statement-case-intro -- the first line in a case alternative block
case-alternative -- a case statement alternative clause
comment -- a line containing only a comment
arglist-intro -- the first line in an argument list
arglist-cont -- subsequent argument list lines when no
arguments follow on the same line as
the arglist opening paren
arglist-cont-nonempty -- subsequent argument list lines when at
least one argument follows on the same
line as the arglist opening paren
arglist-close -- the solo close paren of an argument list
entity -- inside an entity declaration
configuration -- inside a configuration declaration
package -- inside a package declaration
architecture -- inside an architecture body
package-body -- inside a package body
