INTRODUCTION                            Vital.Prelude-introduction

Vital.Prelude is a module for basic functions in Vim script.

NOTE: Some Vital modules implicitly depend on Prelude, because this was used
to be a special module that you could use anywhere without having to
explicitly import.

functions:
See #140 for the details (Japanese).

truncate_skipping({str}, {max}, {footer-width}, {separator})
        This function is deprecated. Please use

        Like a combination of printf() and :execute.

        let x = 123
        call smart_execute_command('echo', x)

        becomes

        execute 'echo' 123


escape_pattern({str})                   Vital.Prelude.escape_pattern()
        Use Vital.Data.String.escape_pattern() instead.
        Note that Vital.Data.String.escape_pattern() does not escape a
        double quotation mark (") while it is not a part of regex pattern.

getchar(...)                                    Vital.Prelude.getchar()
        This is like builtin getchar() but always returns string.

getchar_safe(...)                               Vital.Prelude.getchar_safe()
        This is like builtin getchar() but always returns string,
        and also does inputsave()/inputrestore() before/after getchar().

input_safe(...)                                 Vital.Prelude.input_safe()
        Like builtin getchar() but do inputsave()/inputrestore()
        before/after input().

input_helper({funcname}, {args})                Vital.Prelude.input_helper()
        Do inputsave()/inputrestore() before/after calling a:funcname.

set_default({var}, {val})                       Vital.Prelude.set_default()
        Assign a {val} to a variable which name is {var} if the {var} is
        undefined. Even if the {var} is already defined, if the type of {val}
        is different to the value of {var}, it'll assign anyways.

        For example,

        " not exactly same!
        call set_default('g:aaa', 'bbb')

        Is similar to

        " not exactly same!
        let g:aaa = get(g:, 'aaa', 'bbb')

        But not exactly same when the type of aaa is not expr-string.

                                Vital.Prelude.substitute_path_separator()
substitute_path_separator({path})
        TODO

        echo V.substitute_path_separator('a/b/c')

        is same to

        echo 'a/b/c'

        in most cases but only on Windows it is same to the following.

        echo 'a\\b\\c'


path2directory({path})                  Vital.Prelude.path2directory()
        TODO

        P.path2directory('a/b/c.txt')

        is equivalent to

        P.substitute_path_separator(fnamemodify('a/b/c.txt', ':p:h'))

        and

        P.path2directory('a/b/d') " d is a directory

        is equivalent to

        P.substitute_path_separator('a/b/d')


                                Vital.Prelude.path2project_directory()
path2project_directory({path}[, {is_allow_empty}])
        Look up project root path and return it.

        Project root = <VCS directory> or <Project directory>
        VCS directory = The directory which has
                        ".git" or ".bzr" or ".hg" or ".svn"
        Project directory = The directory which has
                        "build.xml" or "prj.el" or ".project"
                        or "pom.xml" or "package.json" or "Makefile"
                        or "configure" or "Rakefile" or "NAnt.build"
                        or "P4CONFIG" or "tags" or "gtags"

        After failing looking up directory,
        And if {is_allow_empty} was given and non-zero,
        returns {path} which is:
                1. Full Path
                2. On MS Windows, all path separator
                   is replaced by '/'
        Otherwise, empty string was returned.
