end

APPEND(file: '', mode: APPEND_MODE, contents: '') click to toggle source

Writes “contents” to the end of “file”.

# File lib/r7.rb, line 56

        WRITE(file: file, mode: mode, contents: contents)
end

end

PLACE(this_content: '', on_this_line: 1, in_this_file: '') click to toggle source

Returns a new string with content add in place. @example

# This is in a file named: foobar.rb
$foobar = true
# This is in an file named: replace_foobar.r7
# We'll make "foobar" into an instance variable instead...
PLACE(this_content: '@foobar = true', on_this_line: 10, in_this_file: 'foobar.rb')
# Results
@foobar = true

# File lib/r7.rb, line 69
def PLACE(this_content: '', on_this_line: 1, in_this_file: '')
        offset = index_offset(on_this_line)
        contents = READ(file: in_this_file)
        contents = contents.split(NEW_LINE)
        contents.each_index { |i| contents[index_offset(i)] = this_content if i == on_this_line }
        # This corrects an error that occurs when there is no string that follows the index intended to be modified.
        contents[index_offset(on_this_line)] = this_content unless contents[index_offset(on_this_line)] == this_content
        contents.join(NEW_LINE)
end

READ(file: '') click to toggle source

Returns a string with all of the files contents.

# File lib/r7.rb, line 41
def READ(file: '')
        ACCESS(file: file) do |f|
                f.seek(0, :END)
                file_size = f.tell
                f.rewind
                f.read(file_size)
        end
end

REPLACE(this: '', with_this: '', on_this_line: 1, in_this_file: '') click to toggle source

Returns a new string with content replacing a substring. @example

# This is in a file named: foobar.rb
class FooBar
end
# This is in an file named: replace_foobar.r7
# Here we are turning the class into a method definition!
REPLACE(this: 'class', with_this: 'def', on_this_line: 1, in_this_file: 'foobar.rb')
# Results
def FooBar
end

# File lib/r7.rb, line 90
def REPLACE(this: '', with_this: '', on_this_line: 1, in_this_file: '')
        offset = index_offset(on_this_line)
        contents = READ(file: in_this_file)
        contents = contents.split(NEW_LINE)[offset].split
        contents.each_index { |i| contents[i] = with_this if contents[i].include?(this) }
        contents = contents.join(SPACE)
        PLACE(this_content: contents, on_this_line: on_this_line, in_this_file: in_this_file)
end

WRITE(file: '', mode: WRITE_MODE, contents: '') click to toggle source

Writes “contents” to “file”.

# File lib/r7.rb, line 51
def WRITE(file: '', mode: WRITE_MODE, contents: '')
        ACCESS(file: file, mode: mode) { |f| f.write(contents) }
end

index_offset(index) click to toggle source
