Align comments in file, or all files in folder (and optionally their subfolders)
Before
After
Installation
Copy to MATLAB path ("C:\Users\{USERNAME}\Documents\MATLAB") to allow usage everywhere.
Usage
To format all files in active directory, just run "alignComments" in the terminal.
To format a specific file (or all files in a specific folder), "alignComments("FILE_OR_FOLDER_FULL_OR_RELATIVE_PATH")"
To format a specific set of files (or all files in specific folders), "alignComments({"FILES_OR_FOLDERS_FULL_OR_RELATIVE_PATH"})"
To format files without overwriting (output file will be created with the suffix "_new"), "alignComments({OPTIONAL_FILE_OR_FOLDER},'overwrite',0)"
To format files in subfolders as well, enable recursion by "alignComments({OPTIONAL_FILE_OR_FOLDER},'recursive',0)"
NOTE
While no trouble has been reported with the script, the author cannot guarantee that this script won't break your m files, so you are encouraged to use it first without overwriting, just in case the script parses the m file incorrectly and messes it up. In that case, the author suggests you reach out, so bugs/shortcomings can be addressed.
