Coding style

Introduction

Some people might think that the coding style used by the FPC compiler sources and base rtl is a little bit strange but it has been used for a lot of years and isn't subject to be discussed. So take the following as a standard to be used.

Keywords

All keywords are written in lower case. There is no need to make them unreadble by writing them upper case. Modern IDEs support highlighting so keywords will be recognized.

Tabulators

Don't use tabulators. People have different ideas how many chars a tabulator might be so sources using tabulators might look strange.

Indentation

Indentation size is always 2 space characters per level.

Newlines

Newlines are set as it is done by most Object Pascal programs. Between subroutines are two newlines used to separate them.

Misc

Please note that the else in consecutive ifs isn't indented:

if ... then
else if ... then
else if ... then

Examples

How it looks like can be easily checked by having a look at the FPC sources.
