 Main features

- - Padding operators with white spaces based on the configuration.
- - Fixing white space padding of keywords
+ - Padding operators with white spaces based on the XML configuration file.
+ - Correction white space padding of keywords
  - Correction of indentation using the Smart Indent functionality of the Matlab Editor
  - Removal of continuous empty lines (the number can be configured)
- - Optionally inserting missing element separators (commas) in matrix and cell array declarations
- - Different working modes: format the current page of the Matlab editor, format only a selection in the Matlab Editor or format files

 Deployment and Configuration
 ----------------------------
 Add containing directory to the Matlab path, then execute: `MBeautify.setup()`.
 
 This command will create the standard configuration of formatting stored in `MBeautifier\resources\settings\MBeautyConfigurationRules.m`.
 
-This file is used in run-time to gather the configuration rules, therefore when the configuration has been modified, executing this function again will make the rules active.

 All of the operator padding rules are collected dynamically, therefore adding a new node to this list then executing the `setup` command will result in that MBeautifier will replace the currently added node also.

  - Perform formatting on the currently active page of Matlab Editor. Command: `MBeautify.formatCurrentEditorPage()`. By default the file is not saved, but it remains opened modified in the editor. Optionally the formatted file can be saved using the `MBeautify.formatCurrentEditorPage(true)` syntax.
  - Perform formatting on the currently selected text of the active page of Matlab Editor. Command: `MBeautify.formatEditorSelection()`. An optional saving mechanism as above exists also in this case. Useful in case of large files, but in any case `MBeautify.formatCurrentEditorPage()` is suggested.
- - Perfrom formatting on a file. Command: `MBeautify.formatFile(file)`. Can be used with (1)one argument: the input file is formatted and remains open in the Matlab editor unsaved; (2)two arguments as `MBeautify.formatFile(file, outFile)`: the formatted file is saved to the specified output file if possible. Output can be the same as input.

Output can be the same as input.
+ - Perform formatting on several files in a directory. Command: `MBeautify.formatFiles(directory, fileFilter)`. The first argument is an absolute path to a directory, the second one is a wildcard expression (used for `dir` command) to filter files in the target directory. The files will be formatted in-place (overwritten). 
 
  Supported Matlab versions
  -------------------------
 
  As MBeautifier uses the built-in Matlab Editor functionality, it supports Matlab versions from R2011a.
 
+ Planned future versions
+ -----------------------
+ 
+ As Matlab does not contain any formatter even in R2017 releases, this project will be maintained until at least R2018 (if that release will contain a formatter).
+ 
+ As it is planned at the moment, the current release is the last one which is M-Script based, and the next release is planned to be implemented in Java with Matlab interface. This is the first step to make MBeautifier also usable in Octave.
