From Free Pascal wiki
Revision as of 13:16, 9 January 2013 by Wolf (talk | contribs) (procedure list: access via menu and hotkey)

This page contains a list of major IDE features that made Lazarus even more impressive. All features are sorted by the Lazarus release version that they became available in.

If you would like to contribute to this page, please read the following page (Creating animated gifs for wiki) giving hints on creating animated gifs for this wiki.

prior to v0.9.4 (2004 and earlier)

form designer guidelines (June 2002)

The Form Designer shows green or blue guidelines when you position components. This help you align or size components correctly. When components are correctly aligned or sized, then guidelines are shown.

v0.9.10 (2005-10-06)

Integrated Documentation Editor

Lazarus IDE is now capable of editing the external fpdoc help (xml) files while you are working with the source code. The FPDoc Editor can be found at: View -> FPDoc Editor menu option. As you navigate your code, the FPDoc Editor window gets updated with the related documentation. External help files prevent you from obfuscating your source code. fpdoc is similar to the JavaDoc technology, but with its own features and syntax.

v0.9.18 (2006-09-18)

procedure list

This makes finding methods in your current unit really fast! It can be found at Search > Procedure list (Hotkey is Alt+G). The procedure list enables you to view a list of Free Pascal / Lazarus procedures in the current unit and quickly jump to the implementation. Include files are also supported and the method list gets filtered as you type the partial method name.

v0.9.20 (2006-11-05)

divider lines in editor

The Lazarus editor supports drawing horizontal divider lines between classes, methods, nested procedures, begin..end blocks and many more. So now there is no need to add extra blank lines or {*******...} comments between classes or methods. In the upcoming v0.9.28 release this feature is very customizable in the "Environment > Options > Editor > Divider Drawing" screen. In the following screenshot it shows some divider lines using the default color and a divider line for nested procedures using a customized color.

v0.9.24 (2007-11-05)

editor toolbar

The editor toolbar plug-in allows you to define toolbar buttons to any of the IDE menu items.

v0.9.26 (2008-10-25)

fpdoc help inside editor tooltips

Lazarus can now display fpdoc documentation inside the tooltip help. Packages and Project can all be setup to find the related fpdoc (*.xml) help files, which then enables Lazarus to display the extended help in the tooltips. Simply hover the mouse over various parts of the code to see the tooltips in action. In the image below the mouse was hovered over the TCollection class definition.

v0.9.28 (2009-10-12)

block matching

The IDE automatically highlights matching blocks - begin..end pairs.

code macro OfAll

The code templates of the IDE can use code macros. Writing code macros is easy. The new code macro $OfAll() creates a list of enums for case statements as demonstrated in the image below:

(Hint: The separator line between text and folder marks can be enabled via Margin and gutter)

New users will automatically get the new macro. Old users can either delete their ~/.lazarus/lazarus.dci or add the template themselves. How to create the template:

  • IDE menu / Environment / code templates
  • Add. Token: "ofall" or whatever you like. Comment: "case variable of <list of all enums> end"
  • Click ok to add it
  • The new template is selected below.
  • check "Enable macros"
  • The code of the template:
of
|$OfAll()end;
  • click ok to save and close the templates.

Code Templates with macro $Param

To use this feature add the following macro (or delete your old config):

$param(variable) := $param(typename).Create;
try
  |
finally
  $param(variable,sync=1).Free;
end;

Syncron-Edit

v0.9.30 (2011-03-28)

Multi Source Editor

Lazarus can now open as many Source-Editor-Windows as you want, and you can freely move files between them.

It is also possible to view the same file in multiple Windows.

Docked IDE

The IDE now supports docking. Install either the package AnchorDockingDsgn or EasyDockMgrDsgn.

Code folding with hiding option for Comments

Comments in the source code can be completely folded away (hidden). The context menu (on the fold gutter) provides info on the nested folds at the selected line

v1.0 (2012-08-29)

Add new items here.

Folding (Hiding) text by selection

Lazarus can now fold any text/code segment you want. Just select the text and hide it. (These folds are not remembered in the session, restoring folds on load only works for folds at keywords)
