This extension provides fast and streamlined interactive completion based on lines that contain matches for the word to the left of the editing cursor. It's modeled after similar functionality in SlickEdit.
How To Use
Quick Summary
Press "next/prev" keys to choose a completion candidate (based on the word to the left of the editing cursor).
Press a "more" key to insert more of the text from the chosen completion candidate.
When you're done, you don't even have to do anything special -- just do whatever else you were going to do next.
Step by step
Press the "next/prev" keys to start a new interactive completion if one isn't already active.
It searches for completion candidates by matching the word to the left of the editing cursor.
Starting from the match, the rest of the matching line is the "completion candidate".
Ctrl+Shift+, looks for previous candidates (earlier in the document).
Ctrl+Shift+. looks for next candidates (later in the document).
The extension shows feedback at the bottom of the window to indicate the current completion candidate (see Settings for the available feedback modes).
Press the "next/prev" keys repeatedly until you've got the completion candidate you want.
Press the "more" key to insert more of the completion candidate.
Ctrl+Shift+Space inserts up to the end of the next word in the completion candidate.
You can insert as much or as little as you want, up to the end of the candidate's line.
You can change your mind and choose a different completion candidate by pressing the "next/prev" keys again, even after having pressed the "more" key.
When you're done, just start doing something else (or press the Escape key to explicitly end the interactive completion).
Settings
intercomplete.feedbackMode: string enum (see known issues)
"decoration" -- (default) Shows feedback for the current completion using a text decoration at the bottom of the window.
"status bar" -- Shows feedback for the current completion in the status bar.
The feedback modes aren't awesome. Yeah. Unfortunately VSCode is very limited in how an extension can provide feedback to the user.
"decoration" mode can have cosmetic side effects; it forces a horizontal scrollbar to appear, and it can potentially encounter some flicker or jitter. If you experience issues or it's just annoying, try changing to the "status bar" feedback mode via Settings.
"status bar" mode can be overly subtle, and it can potentially encounter jitter or interference with other status bar items.
Know of other approaches? Visit issues and share implementation details or share the name of an extension that uses another approach.
Fast repeated command invocations might get ignored. Yeah. VSCode allows editing commands to run concurrently, and they can garble each other's results.
E.g. holding down a keybinding can garble the results if the previous command invocation(s) haven't finished before the next command invocation starts.
InterComplete compensates by making the new command invocation do nothing if a previous invocation is still processing.
So if you invoke a command 3 times quickly, it's possible that only 1 or 2 keypresses might actually take effect.
It looks like a bug (or design issue) inside VSCode. I'll file an issue against VSCode when I finish getting the callstack analysis and repro packaged up nicely.
The next/prev/more commands are very slow. Yeah, except no. It's because some other extension is being expensive in response to document changes -- try disabling other extensions to track down which one(s).
