vim-coffescript autocommand

[jandob]

I'm using

https://github.com/kchmck/vim-coffee-script.git

and want to apply vim-jsbeautify to the scratch compile buffer
from my vimrc:

augroup CoffeeBufNew
         au!
         autocmd User CoffeeCompile,CoffeeWatch call JsBeautify()
augroup END

When i type ":CoffeeCompile" i get the following error:

Error detected while processing function JsBeautify..Beautifier:
line   54:
E684: list index out of range: 0
E116: Invalid arguments for function setline
Error detected while processing function JsBeautify..Beautifier..<SNR>92_setNumberOfNonSpaceCharactersBeforeCursor:
line    2:
E121: Undefined variable: line
E116: Invalid arguments for function setpos

It seems like the plugin tries to save the cursor position but there is none.

Any help appreciated!

Can you post settings for vim-coffee-script and example of file in which you run CoffeeCompile.
Thanks!

[jandob]

minimal example:
vimrc:

NeoBundle 'einars/js-beautify'
NeoBundle 'maksimr/vim-jsbeautify'
    let g:jsbeautify_file = fnameescape(fnamemodify(expand("<sfile>"), ":h")."/bundle/js-beautify/beautify.js")
NeoBundle 'kchmck/vim-coffee-script'
      augroup CoffeeBufNew
         au!
         autocmd User CoffeeCompile,CoffeeWatch call JsBeautify()
      augroup END

test.coffee:

n = 42

running CoffeeCompile results in the mentioned errror.
Can you reproduce this?

Thanks! Yes

Fix error. But it because compiled file don't has content when calling JsBeautify

[jandob]

Thanks, it works now!
for anyone trying to do the same - i had to tweak the autocommmand a little bit

augroup CoffeeBufUpdate
         au!
         "beautify output
         autocmd User CoffeeCompile,CoffeeWatch set modifiable | call JsBeautify() | set nomodifiable
         "stay inside source buffer
         autocmd User CoffeeCompile,CoffeeRun exec bufwinnr(b:coffee_src_buf) 'wincmd w'
augroup END

Am getting the same error when am trying to beautify a javascript file using :call JsBeautify(). I do not use augroup in my vimrc. Has anyone been able to fix the issue?

[maksimr]

@tispratik can you describe test case?

It reproduce if run vim only with vim-jsbeautify?

[tispratik]

Reproduction steps:

1. Open a new buffer
2. Paste some json string
3. Set file type as javascript :set ft=javascript
4. Beautify. :call JsBeautify()

Interestingly, it does not happen if i skip step number 3

[tispratik]

Also i noticed that it only happens if i have a blank line at the top.

If i delete that blank line and then beautify, this error does not occur.

[maksimr]

Ok! Big Thanks!

[maksimr]

Yup!
The error is associated with the position of the cursor.

If put cursor on first blank line then we get erro

[maksimr]

Move issue to #47
