The following error message appears repeatedly after typing make:

Hello

I noticed that page forward and back do not work (ctrl-f, and ctrl-b).

nice work, btw! :)

If you want to embed vim.js on a bigger page, you need to be able to use keyboard outside vim canvas. Currently the page listens on document and uses preventDefault. I will send a pull request to fix this.

ctrl-n/p in Safari cause screen to scroll.
backspace in Chrome doesn't seem to work.

I tried to compiled the vim.js but got stuck at

      You need to install a terminal library; for example ncurses.
      Or specify the name of the library with --with-tlib.

Havent changed anything in the build.sh. Any idea how to pass this tgetent thing?

I mean is there any way of copying some text from inside of vim and then copy it somewhere else in computer with command-V? Thanks.

Thanks for every distributor, bring so great app,
Now, I expect a interesting using journey.
Thanks to everyone.

But why,
vim is hot, web is hot, js is hot, node is hot,
However,
why does vim.js developing is so cold?
I am so puzzled with this,
Would someone thinks like what I thought?
Would someone discusses on this issue?

Can't delete the characters using "Delete" button in Mac.

I am using Chrome 31 on Mac OS X.

Vim can normally shell out to any program to assist in autocomplete. How can we write such a program in JavaScript, running in the browser, that acts as a program that Vim can "shell out to" in order to determine the completion list?

you could add :h 42 command :)

How did you get a small file of only 5.8 MB?
I compile using emscripten 1.2.9 SDK and build.sh using the features you set but I get a 122 MB file.

I tried running the closure compiler to minify it, but it runs out of memory even with java -Xmx2048m.

With emcc -O2 I get a 33 MB file, but then it doesn't work.

Like how Atom is a standalone web-based editor, make this one standalone. :D

There are several benefits (at least in Firefox) for using async scripts documented here:
https://developer.mozilla.org/en-US/docs/Games/Techniques/Async_scripts

As far as I can see by default only Esc is supported to exit to normal mode (or maybe I'm missing something). But in vim C-c and C-] are doing same task (and they are much more usable). Is there any limitations why C-c and C-] are not implemented?

General feedback from reddit/r/vim was

"this looks awesome! where is textobjects?"

http://www.reddit.com/r/vim/comments/1sspa8/vimjs_javascript_port_of_vim/

This is, for me, pretty critical for a useful vim.

Really cool project though!

See https://blog.mozilla.org/research/2015/02/23/the-emterpreter-run-code-before-it-can-be-parsed/ and https://github.com/kripken/emscripten/wiki/Emterpreter .

This is only a draft, any ideas are welcome.

Motivation

Seems that lots of people are expecting web integrations in vim.js, indeed it might be a good combination for lots of different services, but they might not be necessary for all the users.

A better solution might be to expose enough interface such that people can write and enable only the extensions they need. somewhat like vundle.

Run JavaScript inside Vim.js

Vim script is powerful and widely used, but may be it's too large/slow on vim.js. But sometimes Vim script does not make sense as we have a native JS engine behind it, and javascript is more powerful.

The easiest way of implementation is to hijack :!, it makes sense, easy to use and implement. It's my preferred way, but maybe it will be conflict with existing plugins (suppose that vim script is supported in the future) due to the semantic meaning. But anyway there's no shell (so far) in emscripten and :! won't work anyway...

Otherwise we need to define a new command other than :!, which requires further modification to the original Vim, and I'm kind of against it.

Common functions can be defined inside the vimjs JS Object.

Load external JavaScript

:!vimjs.load_js(url) looks like a good choice

Interaction with Vim.js through JS

To actually access the buffer and other internal structures.

Need lots of work to do, or maybe to enable Vim script instead ... Not sure right now.

File System Extensions

Seems to be popularly demanded, which are fortunately not hard to implement. As long as js can be executed inside vim.js, people can mount different FS using emscripten FS API

Relative libraries:

• BrowserFS
• dropbox-js

Async Function Calls

Sometimes only async functions are available (e.g. setTimeout), such that you cannot block the current execution until some condition is met.

Fortunately Vim.js allows you suspend and resume it, such that you can simulate a blocking operation, which actually blocks Vim.js but does not freeze your browser. An extra callback will be provided to resume Vim.js.

Need to work out a new syntax other than :!, as :! should be reserved as a handy to for sync calls.

I tried specials characters and they don't work on a french or norwegian keyboard.

Tested on Firefox 26.

Esc not works:(

Regardless of whether or not it is a good idea.

Typing :help gives—

E433: No tags file                                                                                                 
E149: Sorry, no help for help.txt 

Program crashes when typing :e . in normal mode. 😢

When pressing the Space key nothing happens.

Window navigation hotkeys seem to conflict with native browser "tab close" hotkeys in Chrome on Linux. Most likely other platforms as well.

When I split the window in two moving up and down breaks the viewport and practically makes it unusable. When one of the two is closed the visual artifacts remain.

Ctrl+Alt+4 gives ¤ instead of $ on Norwegian keyboard

I tried this on a textarea in the same page and it gave the correct $.

The problem would happen if only shift modifier was retained and not ctrl modifier.

I haven't figured out why yet but I am looking at the code.

I will submit a pull request if I figure it out.

is this a bug?

I am using Chrome v33 in Windows 8.1, and I am using the default Chinese Input Engine. I cannot input Chinese in Insert Mode.

Dependencies on Ubuntu are emscripten dependencies and for vim libncurses-dev, libxt-dev and cproto. PS: It can be a bit hard to track down what is missing because make proto will just omit definitions that require more headers rather than fail, so compile will fail later with the missing definitions. You can run e.g.

cd src
gcc -E -DPROTO -DFEAT_SMALL -DFEAT_GUI_WEB ui.c

on the file in question to check for error messages regarding headers.

While running configure, there is a problem that emcc calls clang instead of gcc and then doesn't pick up ncurses system library which makes the configure fail, so before configure do:

cd $EM_DIR
mv emcc emcc.orig
ln -s emcc gcc

Then after configure finishes and before building:

cd $EM_DIR
mv emcc emcc.link
mv emcc.orig emcc

There may be a better way to do this using an environment variable, but I didn't find it.

this combination is used to comment block of code or to indent the block of code.
vim.js, the "try online" version gets stuck with it.

Cool start.

seems, it is only way to support key-in chinese is canvas +(overlay) + input
how did you think? or did you any plan to support chinese?

As seen in the screenshot - wherever the cursor goes, it leaves behind boxes around the characters.

This is on chromium 49.0.2623.112 (64-bit)

I'm not sure what the status of the project is, but if it's permanently unmaintained or abandoned please, please, please archive the repository on GitHub.

Hope all is well, you did a really bad ass job.
