#!/bin/sh
#This is just a smallish indent script to indent mlview
#to indent all the sources correctly (before commiting for ex),
#type:
#./indent-mlview src/*.[ch]
#Here go some explanations of the indent options:
#
#-bad: forces a blank line after every block of declaration
#=============================================================
#-bap: forces a blank line after every procedure body
#=============================================================
#-bbb: forces a blank line before every boxed comment.
#=============================================================
#-sob: forces indent to swallow every optional blank line.
#=============================================================
#-bl -bli2 formats braces like this:
#if (x > 2)
# {
# x-- ;
# }
#=============================================================
#-nce formats the "else" not to cudle up to the
#immediately preceding }:
#if (x > 2)
# {
# x-- ;
# }
#else
# {
# x++ ;
# }
#==============================
#-ce is the contrary of -nce
#=============================================================
#-ss: put a space before a semi colon that is at the same line as a
#for.
#=============================================================
#-pcs: puts a space between the name of a procedure being called
#and the '('.
#=============================================================
#-bs: puts a space between the sizeof operator and its argument.
#=============================================================
#-saf: puts a space between a for an the following parenthesis.
#=============================================================
#-sai: puts a space between an if and its arguments
#=============================================================
#-saw: puts a space between a while and its arguments
#=============================================================
#-psl: causes the type of a procedure being defined to be placed
#on the line before the name of the procedure.
#=============================================================
#-bls: formats braces in struct declarations like this:
#struct foo
#{
# int x;
#};
#-brs: formats braces in struct decls like this:
#struct foo {
# int x;
#};
#=============================================================
#-bc: forces a newline after each comma in a declaration.
#=============================================================
#-i2: puts indentation at 2 blank chars.
#=============================================================
#-lp:
#without -lp the code looks like this:
#p1 = first_procedure (second_procedure (p2, p3),
# third_procedure (p4, p5));
#with -lp the code looks like this:
#p1 = first_procedure (second_procedure (p2, p3),
# third_procedure (p4, p5));
#=============================================================
#-ppi2: indents preprocessor directives using 2 spaces.
#=============================================================
#=============================================================
#-ts2:set tabs spaces to 2 blank chars.
#=============================================================
#-l60 == --line-length60
#=============================================================
#-bbo: break long lines before boolean operators when found.
#=============================================================
