how will the compiler know what file contains myprojects.sysutils ? It will have to index all files in the search path on every compiler start.As reading "SysUtils" will always trigger the assumption RTL This would be confusing to any reader (other than the original author). And while being fully qualified in the uses-clause "myproject.SysUtils", it could occur unqualified in the source (if only the one SysUtils was used): "SysUtils.Foo" or "SysUtils.Exception" (Exception could be redefined in myproject) The name of a common RTL unit (e.g: sysutils) can be redefined.In corner cases, some ambiguities could appear (if the developer doesn't understand the preferences of namespaces).Myproject.SysUtils, // from this project / the myproject namespace. our project also has a SysUtils unit, but because RTL already has one, we So if a project also contains a SysUtils.pas unit, the RTL's SysUtils will take preference, and the developer will have to introduce a project wide namespace. For example the RTL in FPC will not be compiled with a namespace to get higher priority. "global" (or undefined) namespaces take preference.

if a conflict occurs, then you reference the unit with the full namespace.Ĭompanyxyz.utils // because unit names must be valid identifier and thus, $ fpc -namespace=companyxyz utils.pas constants.pas. our sample unit - as normal, nothing new or applied at compile time to all units being compiled. Also add a new -namespace= compiler parameter to apply a namespace to a whole project

Add a new keyword namespace to the Object Pascal language that gets added to the unit line of a source file. They can be applied to a unit, or to a project as a whole. This idea works similar to Compiler Defines. Suggestion 2 - new keyword & new compiler parameter See the following Mantis report for details: Mantis report 14439 Object Pascal already have many language rules, this will just be a new one.

These ideas may or may not work, that's the whole point of this wiki page. This page contains proposals and ideas, which could lead to the a better implementation of namespaces that what Delphi currently has. 4.4.2 Adding / Creating a Namespace / SearchPath-Alias.4.4 Mapping Namespace to each search path.4.2 Suggestion 2 - new keyword & new compiler parameter.4.1 Suggestion 1 - "dotted unit name notation".
