Ada Lovelace

This is the place for learning or remembering all the conventions we are using for writing the Ada wikibooks:

Hint: Keep this page open for cut/copy/paste.

Attribution

[edit source]

Consider creating an account in Wikibooks, it's easy and convenient. You are only requested for a user name and a password. After logging in your contributions are assigned to a name instead of your IP address. It has other benefits see the page Why create an account? from Wikipedia.

Demo Sources

[edit source]

Unlike most other books from the Programming series we aim to provide not only code snippets but also and foremost fully working demos.

In order to ease handling of the demonstration programs a connected SourceForge project called wikibook-ada has been registered.

As a contributer you can take advantage of the svn repository to store your sources. You can also create links from Programming:Ada to your sources using viewscvs. You can use the Template:Ada/Sourceforge to create the links

SourceForge also allows us to offer downloads of all demo sources.

Last but not least, SourceForge provides us download statistics, so we can see if our offer is accepted.

Heading

[edit source]

All pages should have a heading like this: 

<noinclude>
 {{Ada/Navigation}}
 __TOC__
 </noinclude>

Formerly there were "Ada/Navigation 1" to "Ada/Navigation 3" (for one to tree level deep navigation), but they are obsolete now, since the navigation inside the book is provided by the subpage features.

[edit source]

An online documentation like Ada Programming lives from "clickable" text - a click and you get more detail on anything you are interested. So do make links!

Keywords et al.

[edit source]

Language features like Keywords, Pragmas etc. should be written like this: 

 Keywords:         {{Ada/kw|abort}} or {{Ada/keyword|new}}
 Operators:        {{Ada/op|&}} or {{Ada/operator|+}}
                   {{Ada/op|1 = <=}} or {{Ada/op|1 = =}}
 Delimiters:       {{Ada/dl|:}} or {{Ada/delimiter|:}}
                   {{Ada/dl|1 = :=}} or {{Ada/dl|1 = =>}}
 Types:            '''[[Ada Programming/Types/range|range]]'''
 Attributes:       X'{{Ada/at|Access}} or X'{{Ada/attribute|Access}}
 Pragmas:          {{Ada/pragma|No_Return}} or {{Ada/pragma name|No_Return}}
 Packages:         {{Ada/package|Standard}}
 Child Packages:   {{Ada/package|Ada|Text_IO}}, {{Ada/package|Ada|Containers|Vectors}}, ...
 Restrictions:     {{Ada/restriction|No_Obsolescent_Features}} or {{Ada/restriction name|No_Obsolescent_Features}}
 Comments:         {{Ada/--|This is a comment}} or {{Ada/comment|This is a comment}}
 Sourceforge link: {{Ada/Sourceforge|numeric_1.adb}}

which will then look like: 

Keywords:         abort or new
Operators:        & or +
                  <= or =
Delimiters:       : or :
                  := or =>
Types:            range
Attributes:       X'Access or X'Access
Pragmas:          pragma No_Return or No_Return
Packages:         Standard
Child Packages:   Ada.Text_IO, Ada.Containers.Vectors, ...
Restrictions:     pragma Restrictions (No_Obsolescent_Features) or No_Obsolescent_Features
Comments:         -- This is a comment or -- This is a comment

Sourceforge link:

File: numeric_1.adb (view, plain text, download page, browse all)

ASnip, written by User:GorgeUbuasha, can help in the addition of the templates to Ada source code.

Note for Operators
All operators are either a keyword or a delimiter. Hence, all operator pages are only redirects to the appropriate keyword or delimiter. However, in demo sources the rendering of operators, keyword and special character are different.

Normalized sections

[edit source]

The wikibook readability is enhanced if we follow some conventions, like a standard number of sections.

Attributes and pragmas

[edit source]

Sections for pages describing each pragma and attribute (see for example the pages about pragma Atomic and the 'Bit_Order attribute.):

  • syntax summary
  • description, specifying the pragma/attribute category (representation, configuration...) and if it is obsolescent or implementation defined.
  • illustrative example
  • portability:
    • between Ada versions
    • between compilers
    • between platforms (architecture, operating system, embedded/self-hosted, uniprocessor/multiprocessor...)
  • equivalent feature in other languages for interfacing (for pragmas)

Coding rules

[edit source]

Description about how to check good programming practices (e.g. no goto statement) with static analysis tools:

List of templates for the wikibook

This is the list of templates available for the Ada Programming wikibook. See also Category:Book:Ada Programming/Templates.

Language elements

Ada code

Ada language elements
Template Short Notes
{{Ada/keyword}} {{Ada/kw}} Usage:
  • {{Ada/kw|elsif}} gives elsif
{{Ada/operator}} {{Ada/op}}

Normal usage:

  • {{Ada/op|&}} gives &
  • {{Ada/operator|rem}} gives rem (only within paragraphs, use {{Ada/kw}} for code snippets)

When the delimiter contains an equal sign ('=') the explicit named parameter ('1=') is required:

  • {{Ada/op|1==}} gives =
  • {{Ada/op|1=>=}} gives >=
{{Ada/delimiter}} {{Ada/dl}}

Normal usage:

  • {{Ada/dl|'}} gives '

When the delimiter contains an equal sign ('=') the explicit named parameter ('1=') is required:

  • {{Ada/dl|1=:=}} gives :=
  • {{Ada/dl|1==>}} gives =>

For technical limitations the pipe '|' is not allowed as a template parameter, so the ASCII number must be used instead:

  • {{Ada/delimiter|&#124;}} gives |
{{Ada/attribute}} {{Ada/at}}

Usage:

  • {{Ada/attribute|Range}} gives Range

the tick (') is not included by default, but you can add it optionally:

  • {{Ada/at|'|Range}} gives 'Range
{{Ada/package}} {{Ada/pk}} for child packages the template accepts multiple parameters:
{{Ada/aspect}} {{Ada/as}}

Usage:

or Template:Ada/aspect name which does not insert the => delimiter:

{{Ada/pragma}}

Usage:

or Template:Ada/pragma name which does not insert the pragma keyword:

  • {{Ada/pragma name|Pure}} gives Pure
{{Ada/restriction}}

Usage:

or Template:Ada/restriction name which does not insert "pragma Restrictions":

{{Ada/comment}} {{Ada/--}} Usage:
  • {{Ada/--|Line comment}} gives -- Line comment
{{Ada/string}} {{Ada/"}} Usage:
  • {{Ada/"|String literal}} gives "String literal"
{{Ada/character}} {{Ada/ch}} Usage:
  • {{Ada/ch|A}} gives 'A'
{{Ada/integer}} {{Ada/in}}

Normal usage:

  • {{Ada/in|1_024_000}} gives 1_024_000

The base can also be specified (and optionally the exponent):

  • {{Ada/in|16|FFFF_0000}} gives 16#FFFF_0000#
  • {{Ada/in|16|FFFF|4}} gives 16#FFFF#4
{{Ada/real}} {{Ada/re}}

Normal usage:

  • {{Ada/re|3.14159_26535}} gives 3.14159_26535

The base can also be specified (and optionally the exponent):

  • {{Ada/re|16|AB.01}} gives 16#AB.01#
  • {{Ada/re|16|1.F|-2}} gives 16#1.F#-2

Full example: 

 {{Ada/restriction|No_Obsolescent_Features}};
 
 {{Ada/kw|with}} {{Ada/package|Ada|Text_IO}};
 {{Ada/kw|with}} {{Ada/package|Ada|Characters|Latin_1}};
 
 {{Ada/kw|procedure}} Print_Constants {{Ada/kw|is}}
 
    {{Ada/kw|package}} T_IO    {{Ada/kw|renames}} {{Ada/package|Ada|Text_IO}};
    {{Ada/kw|package}} Latin_1 {{Ada/kw|renames}} {{Ada/package|Ada|Characters|Latin_1}};
 
 {{Ada/kw|begin}}
 
    T_IO.Put_Line (Item {{Ada/dl|1==>}} {{Ada/"|Hello!}});        {{Ada/--|String literal}}
    T_IO.Put_Line (Latin_1.Not_Sign {{Ada/op|&}} {{Ada/ch|P}});  {{Ada/--|Character literal (¬P)}}
    T_IO.Put_Line (Integer{{Ada/at|'|Image}} ({{Ada/in|42}}));      {{Ada/--|Integer literal}}
    T_IO.Put_Line (Float{{Ada/at|'|Image}} ({{Ada/re|3.1416}}));    {{Ada/--|Real literal}}
 
 {{Ada/kw|end}} Print_Constants;

gives: 

pragma Restrictions (No_Obsolescent_Features);

with Ada.Text_IO;
with Ada.Characters.Latin_1;

procedure Print_Constants is

   package T_IO    renames Ada.Text_IO;
   package Latin_1 renames Ada.Characters.Latin_1;

begin

   T_IO.Put_Line (Item => "Hello!");        -- String literal
   T_IO.Put_Line (Latin_1.Not_Sign & 'P');  -- Character literal (¬P)
   T_IO.Put_Line (Integer'Image (42));      -- Integer literal

Software

[edit source]

Emacs users might find this Emacs Lisp file helpful when editing Ada programs for inclusion in Wiki pages. ada-to-wiki.el

A similar pure Ada program, ASnip, will do the same using standard input/output. Useful with vi and other editors.

Tracking changes
