1. TED Completion
Command completion gives hints for known matches of input being typed in by the user.
Known matches, if any, appear in the status bar at the bottom of
the screen. If there is a unique match the matching input trailing part of
the match is grayed out, and the leading part
is colored light blue. Typing the <Tab> key at this point will accept
and display the match in green.
In the case of commands, a proc prototype/extern may appear
in the status bar, giving hints on expected arguments.
Command completion can be enabled in Ted via the Preferences/Development/Auto-Completion menu item.
1.1 Selection Popup
To popup the Keyword Selection dialog list, simply use
<Control-space> in a partial match
or after a space char (see
Each item in the popup list has a number/letter prefix to support shortcut
selection/insertion by typing a single char.
As with most transient dialogs in Ted, hitting <Escape> closes the window. Typing slash or clicking <Control-1> over a command completion
will bring up its Man-page (for a command) or Editor (for a proc).
Also, the usual navigation keys work such as: <Control-n> or <Control-d>.
Command completion in TED is provided for two distinct things:
commands and for parameters.
With commands, the first word or command
may be completed with any well-known word. A word is well-known word if
defined as a keyword in the current syntax, or is a key found
in the CTags sidebar (once opened). This provides TED with a simple way
to match commands for languages other than Tcl.
For parameters, completion is available for Tcl commands defining an Extern
(Ted ships with extern definitions for all of Tcl and Tk).
Completion matching is normally limited to items matching the prefix.
However to see all matches, one can type <Control-space>.
1.2 Custom Dialogs
Command arguments may be described via an extern definition, and thus
may have types.
When a type is topts, specific sub-types (such as tkcolor and tkfont)
may have associated dialogs which may be invoked with <Control-Space>
on a line ending with a space. For example:
text new .c -bg <Control-Space>
See the dialog screenshot.
There are several known limitations with the completion implementation.
One current limitation with argument completion is that it works only for Tcl parameters,
and where no preceding parameter contains a braced command sub-call. To work
around this instance, insert arguments at the first parameter position.
