 # Programming Style/Code Formatting
 
-TODO
+In majority of cases a [programming language](programming_language.md) lets the programmer choose the visual/surface style in which to write the code -- one may choose names for variables, indent and align commands in a convenient way, insert comments and so on. This gives rise to various styles -- typically a programmer will have his own preferred style, kind of like handwriting, but once he works in a team, some compromise has to be found to which everyone must conform so as to keep the code nice, consistent and [readable](readability.md). Some project, e.g. [Linux](linux.md), have evolved quite good, tested and de facto standardized styles, so instead of inventing a custom style (which may not be as easy as it sounds) one may choose to adopt some of the existing styles.
+
+There exist automatic code formatters, they are often called **code beautifiers**. But not everything can be automatized, for example inserting empty spaces to separate logically related parts of a sequential of code.

 ## Recommended LRS C Programming Style/Formatting
 
-Here we propose a programming style and C code formatting you may use in your programs. { It's basically a style I personally adopted and fine-tuned over many years of my programming. ~drummyfish } Remember that nothing is set in stone, the most important thing is usually to be consistent within a single project and to actually think about why you're doing things the way you're doing them. Keeping to the standard set here will gain you advantages such as increased readability for others already familiar with the same style and avoiding running into traps set by short-sighted decisions e.g. regarding identifiers. Try to think from the point of view of a programmer who gets just your source code without any way to communicate with you, make his life as easy as possible. The LRS style/formatting rules follow:

Try to think from the point of view of a programmer who gets just your source code without any way to communicate with you, make his life as easy as possible. Also suppose he's reading your code on a calculator. The LRS style/formatting rules follow:
 
 - **Respect the [LRS](lrs.md) design principles** ([KISS](kiss.md), no [OOP](oop.md), avoid dependencies such as [stdlib](stdlib.md) etc.).
 - **Indentation: use two spaces, NEVER use [tabs](tab.md)**. Why? Tabs are ugly, tricky (look the same as spaces) non-standard behaving characters (behavior is dependent on editor and settings, some processors will silently convert tabs and spaces, copy-paste may do so also etc.), they don't carry over to some platforms (especially paper), some very simple platforms may not even support them; your source will contain spaces either way, no need to insert additional blank character.
