I've written a Vim function that formats the file using shfmt. I'd like to know if there is a way I can improve this script.



I am bothered by the fact that I can't think of a way to do this without editing the file in the subprocess and reloading the file. Is there a way to do the equivalent of %!shfmt -options?



if exists("g:loaded_shfmt") || &compatible || ! executable('shfmt')
 finish
endif

let s:save_cpoptions = &cpoptions
set cpoptions&vim

let s:switches = join(['-w', '-s', '-i', '2', '-bn', '-ci', '-sr'])

function! s:shFormat()
 let l:filename = @%
 let l:out = system('shfmt ' . s:switches . ' ' . l:filename)
 edit!
endfunction

nnoremap <silent> <Leader>fb :call <SID>shFormat()<CR>

let &cpoptions = s:save_cpoptions

let g:loaded_shfmt = 1

          Function to Return a JSON Like Objects Using VBA Collections and Arrays

          Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with. Option Explicit Private Function getJSONCollection(ByVal Value As Variant, Optional ScriptEngine As Object) As Variant Const DELIMITER As String = "||" Dim col As Collection, JSON As Object, KeyNam...
