AustinMroz 175ffa64ee examples : vim plugin and LSP server (#1144 ) * Initial proof of concept Vim plugin At present, this is likely only slightly better than feature parity with the existing whisper.nvim Known issues: Trailing whitespace Up to an existing length(5 seconds) of speech may be processed when listening is enabled CPU cycles are spent processing speech even when not listening. Fixing these issues is likely dependent upon future efforts to create a dedicated library instead of wrapping examples/stream * Support $WHISPER_CPP_HOME environment variable A minor misunderstanding of the whisper.nvim implementation resulted in a plugin that was functional, but not a drop in replacement as it should be now. * Initial progress on LSP implementation Libcall is nonviable because the library is immediately freed after a call is made. Further investigation has shown Language Server Protocol as a promising alternative that both simplifies the required logic on the vimscript side and increases the ease with which plugins for other editors could be made in the future. This is a very large undertaking and my progress has slowed substantially. Work is far from being in a usable state, but I wish to keep track of major refactors for organizational purposes. * Rewrite audio windowing of guided transcription One of the defining goals of this venture is allowing consecutive commands to be rattled off without the existing deadzones of the current implementation. * Add unguided_transcription. Cleanup. The unguided transcription implantation heavily borrows from existing example implementations and the guided_transcription logic. A high level pass was done to check that method arguments are accurate to what inputs are actually required. A first attempt at cancellation support was added for record keeping, but will be deleted in a future commit. * Fix compilation. Resolves a large number of compilation errors. No testing has been done yet for execution errors. Update Makefile and .gitignore * Functional unguided_transcription * Functional guided_transcription Fix commandset_list being passed by value Properly register the first token of a multitoken command * Minor changes before time fix I've apparently made an awfully major mistake in thinking that unix time was in milliseconds and will be changing all timekeeping code to use standardized methods. In preparation for this is a number of minor bugfixes. Output is manually flushed. An echo method has been added. registerCommandset now wraps the returned index * Swap timekeeping to use std::chrono * Add work in progress lsp backed whisper.vim plugin Current progress blockers are Adding modality awareness to the command processing (specifically, motion prompting) Improving the VAD to be a little more responsive (testing start of activity) * Reworked vim plugin command loop * Fix change inside Multiple bug fixes that, crucially, bring the plugin to the point where a demonstration video is possible Add better echo messaging so whisper_log isn't required Add loading complete message as indicator when listening has started Insert/append are actually included in command sets Some more heavy handed corrections to prevent a double exit when leaving insert mode As a somewhat hacky fix, the very first space is removed when inserting. This cleans up most use cases, but leaves me unsatisfied with the few cases it would be desired. * Forcibly set commandset_index to 0 after subinsert Also remove unnecessary ! to use builtin vim command * Fix upper A minor scope mistake was causing upper'd inputs to be eaten. This was fixed and echoing was slightly improved for clarity. * Fix formatting Corrects indentation to 4 spaces as project standard Slightly better error support for malformed json input * Remove obsolete vim plugin * Add json.hpp library The same library that is used for the llama.cpp server * Minor cleanups add lsp to the make clean directive. remove a redundant params definition. reorder whisper.vim logging for subtranscriptions Corrections to unlets (variables of argument scope appear immutable) * Fix indentation. Fallback for subTranscription Indentation has been changed to 4 spaces. Unit testing has been set up, I'm opting not to include it in the repository for now. It however, has revealed a bug in the state logic where a subtranscription can be initiated without having a saved command When this occurs, append is added as a fallback * Move audio polling logic to a subfunction While work on the improved vad will continue, It's grown to be a little out of scope. Instead, a future commit will perform multiple detection passes at substretches of audio when a backlog of audio exists. To facilitate this, and prevent code duplication, the vad code has been moved into a subfunction shared by both the unguided and guided transcription functions. * Test for voice over subchunks if backlog > 1s As the existing VAD implementation only checks for a falling edge at the end of an audio chunk. It fails to detect voice in cases where the recorded voice is only at the beginning of the audio. To ameliorate this, when the timestamp would cause analysis of audio over a second in length, it is split into 1 second length subchunks which are individually tested. Results are promising, but there seems to be a remaining bug with unguided transcription likely related to saving context * Limit the maximum length of audio input. This existing VAD implementation only detects falling edges, which means any gap in the users speaking is processed for transcription. This simply establishes a constant maximum length depending on the type of transcription. Uguided gets a generous 10 seconds and guided, 2. While quick testing showed that commands are generally around a half a second to a second, limiting commands to an even second resulted in extreme degradation of quality. (Seemingly always the same output for a given commandset) * Unguided timestamp tracking, cleanup Unguided transcriptions where not setup to allow for passing of timestamp data forward, but have been corrected. No_context is now always set to false. While conceptually desirable for the quality of guided transcription, It was seemingly responsible for prior command inputs ghosting in unguided transcription. Save and Run are now tracked by command number instead of command text. While command_text was provided for convenience, I wish to keep command index authoritative. This gives greater consistency and potentially allows for end users to rename or even translate the spoken versions of these commands * By default, maintain mode. Previously, mode was reset to 0 unless otherwise set. In addition to causing some edge cases, this was didn't mesh well with the existing approach to visual mode. With this change, initial tests indicate visual mode is functional. * Add undo breaks before subtranscriptions Subtranscriptions use undo as a hack to allow for partial responses to be displayed. However, scripts don't cause an undo break mid execution unless specifically instructed to. This meant that multiple unguided transcriptions from a single session would cause a latter to undo a former. This is now fixed and undo should be reasonably usable as a command. * Append instead of insert for new undo sequence When entering and leavening insert mode with `i`, the cursor shifts one column to the left. This is remedied by using append instead of insert for setting these breaks in the undo sequence `-` was also added to the pronunciation dictionary to be pronounced as minus as it was causing a particularly high failure rate. * Move undo sequence breaks to command execution Previously, undo sequence breaks were triggered when there was a command that caused a move to insert mode. This caused commands that changed state (like delete or paste) to be bundled together with into the last command that caused text to be entered. * Fix repeat. Add space, carrot, dollar commands Repeat (.) wasn't being tracked properly just like undo and is being manually tracked now. While efforts have been made to properly handle spaces, it was particularly finicky to add a single space when one is needed. A special 'space' command has been added to insert a single space and move the cursor after it. Carrot and Dollar commands have been added for start of line and end of line respectively. These are both simple to implement, and just a matter of defining a pronunciation. * Return error on duplicate in commandset Not every command in the commandset tokenizes to a single token. Because of this, it's possible for that two commands could resolve to the same single token after subsequent tokens are discarded. This commit adds a simple check for duplicates when a commandset is registered and returns an error if so. Additional code will be required later on the vim side to actually process this error. * Add support for user-defined commands This adds a user definable dictionary from spoken keys to strings or funcrefs. All keys are added to the commandlist and when spoken, trigger the corresponding function. Like "save" and "run", these user commands are only available when the command buffer is empty. * Add readme, update cmake * Add area commandset. Refactor spoken_dict Area commands (inside word, around sentence...) have been given a commandset as considered earlier. Verbose definitions for spoken_dict entries now use dicts instead of lists. This shortens the definition for most keys that require it and scales better with the addition of further commandsets * Add mark, jump. Fix change under visual. Mark (m) and jump (') have been added. When a visual selection was executed upon a command that initiated a subtranscription (change) the area of the visual selection is not properly tracked which causes the attempt to stream in partial response to fail. This is solved by disabling partial transcriptions from being streamed when a subtranscription is started while in visual mode. * Accommodate ignorecase. Fix change. From testing on older different versions of vim, the test for distinguishing an 'R' replace all from an 'r' replace could fail if ignorecase was set. The comparison has been changed to explicitly require case matching Change detection has been moved to the execution section as it was missing the change+motion case. * Support registers. Fix README typo There's no logic to prevent doubled register entry, but the functional result is equivalent to if the same key order was typed into vim. A minor typo in the readme. I've mismemorized the mnemonic for 't' as 'to' instead of till., but 'to' can't be used as it's a homophone with '2'. While there was no mistake in the actual logic, it was misleading to use 'to' in the readme.	2023-08-27 21:35:06 +03:00

examples : vim plugin and LSP server (#1144 )

* Initial proof of concept Vim plugin

At present, this is likely only slightly better than feature parity with
the existing whisper.nvim

Known issues:
 Trailing whitespace
 Up to an existing length(5 seconds) of speech may be processed when
  listening is enabled
 CPU cycles are spent processing speech even when not listening.

Fixing these issues is likely dependent upon future efforts to create a
dedicated library instead of wrapping examples/stream

* Support $WHISPER_CPP_HOME environment variable

A minor misunderstanding of the whisper.nvim implementation resulted in
a plugin that was functional, but not a drop in replacement as it should
be now.

* Initial progress on LSP implementation

Libcall is nonviable because the library is immediately freed after a
call is made. Further investigation has shown Language Server Protocol as
a promising alternative that both simplifies the required logic on the
vimscript side and increases the ease with which plugins for other
editors could be made in the future. This is a very large undertaking
and my progress has slowed substantially.

Work is far from being in a usable state, but I wish to keep track of
major refactors for organizational purposes.

* Rewrite audio windowing of guided transcription

One of the defining goals of this venture is allowing consecutive
commands to be rattled off without the existing deadzones of the current
implementation.

* Add unguided_transcription. Cleanup.

The unguided transcription implantation heavily borrows from existing
example implementations and the guided_transcription logic.

A high level pass was done to check that method arguments are accurate
to what inputs are actually required.

A first attempt at cancellation support was added for record keeping,
but will be deleted in a future commit.

* Fix compilation.

Resolves a large number of compilation errors.
No testing has been done yet for execution errors.

Update Makefile and .gitignore

* Functional unguided_transcription

* Functional guided_transcription

Fix commandset_list being passed by value
Properly register the first token of a multitoken command

* Minor changes before time fix

I've apparently made an awfully major mistake in thinking that unix time
was in milliseconds and will be changing all timekeeping code to use
standardized methods.

In preparation for this is a number of minor bugfixes.
Output is manually flushed.
An echo method has been added.
registerCommandset now wraps the returned index

* Swap timekeeping to use std::chrono

* Add work in progress lsp backed whisper.vim plugin

Current progress blockers are
 Adding modality awareness to the command processing
  (specifically, motion prompting)
 Improving the VAD to be a little more responsive
  (testing start of activity)

* Reworked vim plugin command loop

* Fix change inside

Multiple bug fixes that, crucially, bring the plugin to the point where a
demonstration video is possible

Add better echo messaging so whisper_log isn't required
 Add loading complete message as indicator when listening has started
Insert/append are actually included in command sets
Some more heavy handed corrections to prevent a double exit when leaving
insert mode
As a somewhat hacky fix, the very first space is removed when inserting.
 This cleans up most use cases, but leaves me unsatisfied with the few
 cases it would be desired.

* Forcibly set commandset_index to 0 after subinsert

Also remove unnecessary ! to use builtin vim command

* Fix upper

A minor scope mistake was causing upper'd inputs to be eaten.
This was fixed and echoing was slightly improved for clarity.

* Fix formatting

Corrects indentation to 4 spaces as project standard
Slightly better error support for malformed json input

* Remove obsolete vim plugin

* Add json.hpp library

The same library that is used for the llama.cpp server

* Minor cleanups

add lsp to the make clean directive.
remove a redundant params definition.
reorder whisper.vim logging for subtranscriptions
Corrections to unlets (variables of argument scope appear immutable)

* Fix indentation. Fallback for subTranscription

Indentation has been changed to 4 spaces.

Unit testing has been set up, I'm opting not to include it in the
repository for now.
It however, has revealed a bug in the state logic where a
subtranscription can be initiated without having a saved command
When this occurs, append is added as a fallback

While work on the improved vad will continue, It's grown to be a little

passes at substretches of audio when a backlog of audio exists.

recorded voice is only at the beginning of the audio.

over a second in length, it is split into 1 second length subchunks
which are individually tested.

While quick testing showed that commands are generally around a half a

* Unguided timestamp tracking, cleanup

Unguided transcriptions where not setup to allow for passing of
timestamp data forward, but have been corrected.

No_context is now always set to false. While conceptually desirable for
the quality of guided transcription, It was seemingly responsible for
prior command inputs ghosting in unguided transcription.

Save and Run are now tracked by command number instead of command text.
While command_text was provided for convenience, I wish to keep command
index authoritative. This gives greater consistency and potentially
allows for end users to rename or even translate the spoken versions of
these commands

* By default, maintain mode.

Previously, mode was reset to 0 unless otherwise set.

Subtranscriptions use undo as a hack to allow for partial responses to
be displayed. However, scripts don't cause an undo break mid execution
unless specifically instructed to. This meant that multiple
unguided transcriptions from a single session would cause a latter to
undo a former.

This is now fixed and undo should be reasonably usable as a command.

* Append instead of insert for new undo sequence

When entering and leavening insert mode with `i`, the cursor shifts one
column to the left. This is remedied by using append instead of insert
for setting these breaks in the undo sequence

`-` was also added to the pronunciation dictionary to be pronounced as
minus as it was causing a particularly high failure rate.

* Move undo sequence breaks to command execution

Previously, undo sequence breaks were triggered when there was a command
that caused a move to insert mode. This caused commands that changed
state (like delete or paste) to be bundled together with into the last
command that caused text to be entered.

* Fix repeat. Add space, carrot, dollar commands

 Repeat (.) wasn't being tracked properly just like undo and is being

the corresponding function.

Like "save" and "run", these user commands are only available when the
command buffer is empty.

* Add readme, update cmake

* Add area commandset. Refactor spoken_dict

Area commands (inside word, around sentence...) have been given a
commandset as considered earlier.

Verbose definitions for spoken_dict entries now use dicts instead of
lists. This shortens the definition for most keys that require it and
scales better with the addition of further commandsets

* Add mark, jump. Fix change under visual.

Mark (m) and jump (') have been added.

When a visual selection was executed upon a command that initiated a
subtranscription (change) the area of the visual selection is not
properly tracked which causes the attempt to stream in partial response
to fail. This is solved by disabling partial transcriptions from being
streamed when a subtranscription is started while in visual mode.

* Accommodate ignorecase. Fix change.

From testing on older different versions of vim, the test for
distinguishing an 'R' replace all from an 'r' replace could fail if
ignorecase was set. The comparison has been changed to explicitly
require case matching

Change detection has been moved to the execution section as it was missing the

whisper.nvim

Speech-to-text in Neovim

The transcription is performed on the CPU and no data leaves your computer. Works best on Apple Silicon devices.

https://user-images.githubusercontent.com/1991296/198382564-784e9663-2037-4d04-99b8-f39136929b7e.mp4

Usage

Simply press Ctrl-G in INSERT, VISUAL or NORMAL mode and say something
When you are done - press Ctrl-C to end the transcription and insert the transcribed text under the cursor

Installation

Note: this is a bit tedious and hacky atm, but I hope it will be improved with time

Clone this repo and build the stream tool:

git clone https://github.com/ggerganov/whisper.cpp
cd whisper.cpp
make stream

Download the base.en Whisper model (140 MB):
```
./models/download-ggml-model.sh base.en
```
Place the whisper.nvim script somewhere in your PATH and give it execute permissions:
```
cp examples/whisper.nvim/whisper.nvim ~/bin/
chmod u+x ~/bin/whisper.nvim
```
Fine-tune the script to your preference and machine parameters:
```
./stream -t 8 -m models/ggml-base.en.bin --step 350 --length 10000 -f /tmp/whisper.nvim 2> /dev/null
```
On slower machines, try to increase the step parameter.
Add the following shortcuts to your ~/.config/nvim/init.vim:
```
inoremap <C-G>  <C-O>:!whisper.nvim<CR><C-O>:let @a = system("cat /tmp/whisper.nvim \| tail -n 1 \| xargs -0 \| tr -d '\\n' \| sed -e 's/^[[:space:]]*//'")<CR><C-R>a
nnoremap <C-G>       :!whisper.nvim<CR>:let @a = system("cat /tmp/whisper.nvim \| tail -n 1 \| xargs -0 \| tr -d '\\n' \| sed -e 's/^[[:space:]]*//'")<CR>"ap
vnoremap <C-G> c<C-O>:!whisper.nvim<CR><C-O>:let @a = system("cat /tmp/whisper.nvim \| tail -n 1 \| xargs -0 \| tr -d '\\n' \| sed -e 's/^[[:space:]]*//'")<CR><C-R>a
```
Explanation: pressing Ctrl-G runs the whisper.nvim script which in turn calls the stream binary to transcribe your speech through the microphone. The results from the transcription are continuously dumped into /tmp/whisper.nvim. After you kill the program with Ctrl-C, the vim command grabs the last line from the /tmp/whisper.nvim file and puts it under the cursor.

Probably there is a much more intelligent way to achieve all this, but this is what I could hack in an hour. Any suggestions how to improve this are welcome.

You are now ready to use speech-to-text in Neovim!

TODO

There are a lot of ways to improve this idea and I don't have much experience with Vim plugin programming, so contributions are welcome!

Wrap this into a plugin

It would be great to make a standalone plugin out of this that can be installed with vim-plug or similar
Simplify the init.vim mappings (maybe factor out the common call into a separate function)
Add Copilot/GPT-3 integration

This is probably a very long shot, but I think it will be very cool to have the functionality to select some code and then hit Ctrl-G and say something like:

"refactor this using stl containers"

or

"optimize by sorting the data first"

The plugin would then make an appropriate query using the selected text and code context to Copilot or GPT-3 and return the result.

Here is a proof-of-concept:
