==Language consideration==
|
||||
* Do not put a blank line between
|
||||
:* '''create''' and creation instructions
|
||||
:* '''inherit''' and parent clauses
|
||||
* Do not use assertion clauses without tag names.
|
||||
|
||||
A sample of proper formatting of code:
|
||||
<e>note
|
||||
description: "Descr...."
|
||||
date: "$date: $"
|
||||
|
||||
class A
|
||||
|
||||
inherit
|
||||
B
|
||||
rename
|
||||
f as g
|
||||
end
|
||||
|
||||
create
|
||||
make
|
||||
|
||||
feature {NONE} -- Initialization
|
||||
|
||||
make (a: INTEGER)
|
||||
-- Initialize Current with `a`.
|
||||
do
|
||||
end
|
||||
|
||||
invariant
|
||||
a_positive: a > 0
|
||||
|
||||
end</e>
|
||||
|
||||
==Style==
|
||||
* If instructions:
|
||||
<e>if expr1 then
|
||||
...
|
||||
elseif expr2 then
|
||||
...
|
||||
else
|
||||
...
|
||||
end</e>
|
||||
|
||||
If expressions are very long, break them on conjunctions as in:
|
||||
<e>if
|
||||
expr1 and then
|
||||
expr2
|
||||
then
|
||||
...
|
||||
end</e>
|
||||
|
||||
* Loop instructions:
|
||||
<e>from
|
||||
...
|
||||
until
|
||||
...
|
||||
loop
|
||||
...
|
||||
end</e>
|
||||
|
||||
* Inspect instructions:
|
||||
<e>inspect expr
|
||||
when val1 then ....
|
||||
else
|
||||
...
|
||||
end</e>
|
||||
|
||||
or
|
||||
|
||||
<e>inspect
|
||||
expr
|
||||
when val1 then
|
||||
...
|
||||
else
|
||||
...
|
||||
end</e>
|
||||
|
||||
* For punctuation, we always have
|
||||
** a space before, and no after `(`
|
||||
** no space before, and space after `)` `,` `:` or `;`
|
||||
|
||||
<e>require
|
||||
a_tag: query (a, b, c) or other_query (c, d)
|
||||
local
|
||||
i: INTEGER; j: INTEGER
|
||||
</e>
