json-ponyfill.vim

Provide json_decode and json_encode to the former version of VIM.

function! s:json_decode(json)
  if !exists("*json_decode")
    return json_ponyfill#json_decode(a:json)
  endif
  return json_decode(a:json)
endfunction

function! s:json_encode(json)
  if !exists("*json_encode")
    return json_ponyfill#json_encode(a:json)
  endif
  return json_encode(a:json)
endfunction

Install (Pathogen)

git clone https://github.com/retorillo/json-ponyfill.vim ~/.vim/bundle/json-ponyfill.vim

Performance problem and workarounds

json_ponyfill#json_decode and json_ponyfill#json_encode will take a long time working with large JSON.

Of course my code may be not sophisticated, but originally Vim Script is not good for large processing.

Consider to use the following workarounds:

Using python if possible

Use json_ponyfill#json_decode(json, { 'python': 1 }) to use python if possible.

Python can process faster than Vim Script.

Displaying progress bar

Use json_ponyfill#json_decode(json, { 'progress': 1 }) to display progress bar like below:

json_decode  50% [=========================.........................]

NOTE: Progress bar use redraw command to refresh itself. redraw command wipe previously printed all echo message out. See :h redraw, :h messages, :h echomsg, and :h echoerr to learn more.

Combining the above workarounds

Of course, the above options can be combined like: json_ponyfill#json_decode(json, { 'progress': 1, 'python': 1 }. But note that progress option will be ignored if python is available.

Unit testing (For plugin developers)

test/test.vim is a bit useful snippet for unit testing.

:let g:json_ponyfill = 1 | source test/test.vim
