Abstract:
Functions to beautify code.
Goals:
- Highly customizable.
- Beautification of whole sources. For example a unit, or several
sources.
- Beautification of parts of sources. For example selections.
- Beautification of insertion source. For example beautifying code, that
will be inserted in another source.
- Working with syntax errors. The beautification will try its best to
work, even if the source contains errors.
- Does not ignore comments and directives
- Contexts: statements, declarations
Examples for beautification styles:
if expr then
begin
;
end;
if expr then
...
else
...;
