.. _tcl:
======================================================================
The new Tcl parser
======================================================================
:Maintainer: Masatake YAMATO <yamato@redhat.com>
Tcl parser is rewritten as a token oriented parser to support
namespace. It was line oriented parser. Some incompatibility between
Exuberant Ctags is introduced in the rewriting.
The line oriented parser captures `class`, `public|protected|private
method`. They are definitions in ITcl and TclOO. The new token oriented Tcl
parser ignores them. Instead ITcl and TclOO subparser running on Tcl base
parser capture them.
Known bugs
----------------------------------------------------------------------
Full qualified tags
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The separator used in full qualified tags should be `::` but `.` is
used.
A ITcl or TclOO class `C` can be defined in a Tcl namespace `N`:
.. code-block:: Tcl
namespace eval N {
oo::class create C {
}
}
When ``--extras=+q`` is given, currently ctags reports::
N.C ...
This should be::
N::C ...
Much work is needed to fix this.
Nested procs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
`proc` defined in a `proc` cannot be captured well.
This is a regression.
