Code Explorer Options

The dialog is explained here: IDE Window: Code Explorer


Preferred Exhibition Mode
  • Category - sort all declarations into categories like constants, variables, types, procedures, ...
  • Source - show all declarations as they are in the source
Refresh automatically
  • Never, only manually - only when pressing the Refresh button
  • When switching file in source editor - when switching to another unit
  • On idle - whenever the user does not type or move the mouse


Shows the available categories. Check all that you want to see in the code explorer.

The category Code Observer exists since 0.9.27 and lists uncommon or hard to read code fragments. You can set the details in the next option page.

Code Observer

  • Long procedures
    Lists all procedures with more lines of code than in the edit field to the right. Long procedures are hard to read by others. Use the Extract Procedure tool to split it into several procedures.
  • Many parameters
    Lists all procedures with more parameters than in the edit field to the right.
  • Many nested procedures
    Lists all procedures with more nested sub procedures than in the edit field to the right.
Empty constructs
  • Empty procedures
    Lists all procedures without code. They can contain comments and directives. The code below will be listed under linux.
  {$IFDEF win32}write;{$ENDIF} 
  • Empty blocks
    Lists all empty blocks, like begin..end and repeat..until. Blocks containing comments are not listed. Empty blocks can be endless loops or forgotten to clean up.
  • Empty class sections
    Lists all empty class sections like private, public, protected.
  • Unnamed Constants
    Lists all literal constants in statements, that means constants that have no name. You can define in the text fields below what should not be listed.
  • Unsorted visibility
    Lists all class sections, that are not sorted. For example if a private section comes behind a public section.
  • Unsorted members
    Lists all class variables, methods and properties that are not sorted alphabetically.
  • Wrong indentation
    Lists all places with suspicious indentation. For example: In the next example the then statement was accidentally deleted:
for i:=0 to 10 do
  if i=0 then
  • Published properties without default
    Lists all properties without a default value. For example:
  property Flag: booolean read FFlag write SetFlag;

Since FPC 2.2.4 such properties are treated as if they have the nodefault specifier. That means they are always saved to the lfm.

Ignore next unnamed constants

These constants will not be listed in the unnamed category. Examples:

Ignore constants in next functions

Constants passed as parameters to the following functions will not be listed in the unnamed category. There are two types. For example:


Note the point in front of ParamByName.


Write('A'); // 'A' will be ignored
MemStream.Write('A'); // 'A' will be listed
DataModule1.SQLQuery1.Params.ParamByName('ART_ID').AsString; // will be ignored
ParamByName('ART_ID').AsString; // will be listed
