" Vim indent file
" Language:     Erlang (http://www.erlang.org)

" License:      Vim license

" Note About Usage:
"   This indentation script works best with the Erlang syntax file created by
"   Kreąimir Marľić (Kresimir Marzic) and maintained by Csaba Hoch.

" Notes About Implementation:
"
" - LTI = Line to indent.
" - The index of the first line is 1, but the index of the first column is 0.


" Initialization {{{1
" ==============

" Only load this indent file when no other was loaded
" Vim 7 or later is needed
if exists("b:did_indent") || version < 700
  finish
else
  let b:did_indent = 1
endif

setlocal indentexpr=ErlangIndent()
setlocal indentkeys+=0=end,0=of,0=catch,0=after,0=when,0=),0=],0=},0=>>

" Only define the functions once
if exists("*ErlangIndent")
  finish
endif

let s:cpo_save = &cpo
set cpo&vim

" Logging library {{{1
" ===============

" Purpose:
"   Logs the given string using the ErlangIndentLog function if it exists.
" Parameters:
"   s: string
function! s:Log(s)
  if exists("*ErlangIndentLog")
    call ErlangIndentLog(a:s)
  endif
endfunction

" Line tokenizer library {{{1
" ======================

" Indtokens are "indentation tokens".

" Purpose:
"   Calculate the new virtual column after the given segment of a line.
" Parameters:
"   line: string
"   first_index: integer -- the index of the first character of the segment
"   last_index: integer -- the index of the last character of the segment
"   vcol: integer -- the virtual column of the first character of the token
"   tabstop: integer -- the value of the 'tabstop' option to be used
" Returns:
"   vcol: integer
" Example:
"   " index:    0 12 34567
"   " vcol:     0 45 89
"   s:CalcVCol("\t'\tx', b", 1, 4, 4)  -> 10
function! s:CalcVCol(line, first_index, last_index, vcol, tabstop)

  " We copy the relevent segment of the line, otherwise if the line were
  " e.g. `"\t", term` then the else branch below would consume the `", term`
  " part at once.
  let line = a:line[a:first_index : a:last_index]

  let i = 0
  let last_index = a:last_index - a:first_index
  let vcol = a:vcol

  while 0 <= i && i <= last_index

    if line[i] ==# "\t"
      " Example (when tabstop == 4):
      "
      " vcol + tab -> next_vcol
      " 0 + tab -> 4
      " 1 + tab -> 4
      " 2 + tab -> 4
      " 3 + tab -> 4
      " 4 + tab -> 8
