Describe the bug

VimWasm.cmdline() runs given command, but screen is not updated. To avoid this, appending | redraw to the command is necessary.

Steps To Reproduce

1. Visit https://rhysd.github.io/vim.wasm/?debug=1
2. Open DevTools console
3. Run vim.cmdline('edit ~/.vim/vimrc')

Expected behavior

Screen renders the content of ~/.vim/vimrc

What is an issue which you want to solve with your feature request?

Working in Firefox (And maybe other browsers).

Describe the solution you'd like

• Host somewhere that support custom headers (like netlify)
• Add coop and coep headers

try:

:colo ((press C-D))

it does not output the possible completions.
The options are shown using , as expected, though.

On https://rhysd.github.io/vim.wasm/ page,
I type the following sequence
ihohoho<esc>
:%s/o/i/gc<enter>

I then cannot do anything else, page seem to be "frozen".

Repro.

1. Write something multiline
2. Into the Visual-mode
3. Select an area
4. Do replace or something to selected area

Screenshot

Describe the bug
In vim previous commands entered (possibly only the ones that executed successfully, I'm not too sure I'm afraid) can be replayed by pressing up in command mode.

Steps To Reproduce
type
:%s/foo/bar/
then press enter
then type (colon, then press up arrow)
:<Up>

Expected behavior
:%s/foo/bar/
is in the command bar, ready to be executed by pressing enter

Actual behavior
prints a literal
:<Up>
to the command bar, rather than displaying previous command -> :%s/foo/bar/

Screenshots/DevTools console (if possible)
see bottom, sorry there's a lot on the console

If you enter a command like :w filename, and hit enter, then press : to get back to command mode and press the up arrow key, it should go back in the command history and pull up :w filename, but instead it inserts :<Up>. This happens with all four arrow keys.

As described in known issues, disabling Emterpreter would make execution more stable and faster. For that, an event loop for waiting user input must be async to use JavaScript's setTimeout().

I looked in the readme, but didn't see anything. Is there any relationship between this project and https://github.com/coolwanglu/vim.js ?

Great work! 👏

What is an issue which you want to solve with your feature request?

The installation process of vim.wasm is not documented.

Describe the solution you'd like

Provide installation instruction or provide a Dockerfile for quick deployement.

Thank you, very neat project.

In most cases, the vimWasm.cmdline() method does not work as expected. I anticipate that cmdline() should function similarly to manually using Vim's execution mode.

Here are examples of bugs:

• vimWasm.cmdline('startinsert') should change Vim to insert mode, but it does not work.

• vimWasm.cmdline('2') is supposed to move the cursor to line 2, but I don't see the cursor updating. Even after trying to redraw vimWasm.cmdline('2 | redraw'), it still doesn't work.

@rhysd Please help to find solutions. Thanks

There is a project called PDCurses.js which actually allows linking with lcurses. Just wondering if you have considered using it instead of writing the terminal interaction manually. The advantage would be to compile the original project without the need to hack the original files and its compiled size is small too.

What is an issue which you want to solve with your feature request?

One of the problems with vim.wasm is that there is no facility to choose where to save the typed code. This is a problem when you write code and want the copy to be kept somewhere else for backup or for data security reasons.

Describe the solution you'd like

I would like to have an option in vim.wasm to choose the storage location. For example, I could save all the code I'm typing in vim.wasm directly to google drive, dropbox, trezorit or I could save it through a protocol like IPFS, FTP etc.

Additional context (if any)

• IPFS
• Google drive api
• dropbox api
• ftp
• remote-storage

This is not an issue, nor appropriated for the Vim mailing list. However, since this is basically a version of Vim for the web it would make sense to offer some of the features you would expect from a web editor, such as saving. The :w command could for example trigger a file download. Likewise, opening a file could ask the user to select a file to upload.

Trying to generate the vim.wasm file from a release tarball, I get an error because there's no .git folder. I understand this behaviour is to prevent errors, but in that case, I think is superfluous and should be removed.

Describe the bug

When trying to use the regular command to switch splits, the browser intercepts the command and tries to close the browser window

Workaround

In the help text, introduce the ':winc " for moving between splits.

Steps To Reproduce

Open vim.wasm
split a window ( :sp )
Try to use ctrl-w to move windows

• The browser will try to close the browser tab

Thanks to @tyru for the report

What is an issue which you want to solve with your feature request?

I want to have a single "vim.html" where everything is contained, even if it makes the file bigger. I already embedded the "VimWasm.js" inside a <script>.

So in this I only have to "import" the "vim.js" file like this:

const screenCanvasElement = document.getElementById('vim-screen');
const vim = new VimWasm({ // VimWasm is available in the global scope via window.VimWasm(loaded via <script>)
    workerScriptPath: './node_modules/vim-wasm/small/vim.js',
    canvas: screenCanvasElement,
    input: document.getElementById('vim-input'),
});

The problem is that when you're inside of vim.js it uses fetch to get the vim.wasm binary so you need a server running to have this working.

Describe the solution you'd like

The solutions would be that you can actually embed .wasm inside of a .html file via base64 encoding, this might not be the most good for performance but for portability it's great!( see https://stackoverflow.com/questions/52582367/a-single-file-webassembly-html-demo and https://gist.github.com/dio/ae79cf546e808a9bc46515bf9400ad5d)

I have tried edit the code myself but it uses both WebAssembly.instantiate and WebAssembly.instantiateStreaming so I'm not exactly sure what to do thus I'm opening this issue.

Additional context (if any)

Describe the bug

The page stays black when accessing https://rhysd.github.io/vim.wasm/ with firefox.
" '' should be object " appears on the bottom of the page as shown in the attached image.

Steps To Reproduce

1. Access https://rhysd.github.io/vim.wasm/ with firefox: will stay black (nothing be shown on the page).
2. Restart firefox, then you'll the screen as shown attached.

Expected behavior

The screen like vim will appear.

Actual behavior

The page stays black.

Ideally this would result in an alert saying "Type :qa! and press to abandon all changes and exit vim". Anything else is simply not true to the vim experience (ignoring for the moment that :q doesn't actually work, which it probably should)

What is an issue which you want to solve with your feature request?

We have a Qt-based desktop application for medical image processing and we use python code as a kind of macro language to extend and automate the program.

We'd like to be able to use a full featured editor integrated within the application to work with our python code.

Because our app uses Qt, we have the QWebEngine available and can embed a full featured web browser in our app, and we can call browser's javascript environment from python (e.g. like in this test code). Note that it's all asynchronous on both the javascript and python sides.

Recently the question came up about using a full editor to edit the python code in our app, and I found that I can run you vim.wasm code in our embedded browser:

https://discourse.slicer.org/t/directly-interacting-with-python-console/34455/7

But I don't see any easy way to get/set the contents of the editor window or be notified in javascript of vim events.

Describe the solution you'd like

I'd like to be able to start the vim.wasm context in the browser and then call a javascript function to populate the current text buffer for editing. Then I'd like to be able to use vim keystrokes to trigger javascript code in the browser that would make calls back to the python code, for example to send selection buffers to python for execution.

I tried using the ?debug argument to set the vim object as window.vim and while I could access vim in the debug console I didn't see any way to set or get the values of the current vim buffers. It would be great if window.vim were available to interact with the browser's javascript enviornment.

Thanks in advance - I'm a long-time vi/vim user and having this available would make me very happy : )

To replicate:

1. Hit "i" to go to insert mode and try writing something
2. Hit to go back to normal mode
3. Move to the middle of a word
4. Try typing "diw" to delete inner word in normal mode

Nothing happens.

What is an issue which you want to solve with your feature request?

Allow the live demo to be installed as a PWA (Progressive Web App).

Allowing the live demo to be installed could include great features such as:

• Offline Support.
• Open text/script files directly from the file system (https://web.dev/file-handling/).
• Open vim.wasm into a clear buffer (without a tryit.js buffer) (https://web.dev/app-shortcuts/).

Describe the solution you'd like

Implement a service worker to cache vim.wasm and the files to run it in the browser.
Add a web manifest to help the browser install it.

Additional context (if any)

Some good tutorials can be found at web.dev (https://web.dev/tags/progressive-web-apps/)

Is there a reason why there is only a single colorscheme; https://github.com/rhysd/vim.wasm/tree/wasm/wasm/usr/local/share/vim/colors

Is it possible to have more colorschemes; https://github.com/vim/vim/tree/master/runtime/colors

After cloning the repo and building it using ./build.sh, running a local server and hosting vim.html raises quite a few errors.

Following the steps under Development of the README file, raised these errors.

Vim should run without any problems in the browser

But what I see is a blank screen with multiple errors in the console

Your environment:

• OS: Ubuntu 18.04
• Browser: Google Chrome
• Browser Version: 74.0.3729.169

Is your feature request related to a problem? Please describe.

I couldn't paste some code I wanted to reformat. Felt like vim.wasm could possibly do this, (mostly for convenience) on a Chromebook. 😄

In particular, I wanted a simple reformat, which I knew I could do quickly in Vim:

In:

#Array
#Complex
#Float
#Hash
#Integer
#Rational
#String

Out:

(`Array()`, `Complex()`, `Float()`, `Hash()`, `Integer()`, `Rational()`, `String()`)

Describe the solution you'd like

Add support for pasting via Ctrl-V/Cmd-V, "+p, or another solution. Add a short blurb somewhere on the page describing this.

Additional context (if any)

Resizing the browser window isn't triggered as resizing the terminal, instead it just squishes and stretches the rendering.

Could you create a page that pre-populates this with the text of vimtutor?
http://www2.geog.ucl.ac.uk/~plewis/teaching/unix/vimtutor

This would be a really cool tool for trying out vim!

BTW, this project is a great idea! - I have been wondering for years how getting Vim going in the browser might be done!
