Is there a way to fix all MATLAB mlint messages at once?

Question

I\'ve inherited some code where the author had an aversion to semicolons. Is it possible to fix all the mlint messages in one go (at least all the ones with an automatic fi

I know this is an old post but I just needed this recently and improved a bit on the original code so if anybody else needs it here it is. It looks for missing ";" in functions, not just in regular scripts, maintains the whitespace in code and writes only files that have something changed.

function [] = add_semicolon(fileName)
%# Find the lines where a given mlint warning occurs:

mlintIDinScript = 'NOPTS';                       %# The ID of the warning
mlintIDinFunction = 'NOPRT';
mlintData = mlint(fileName,'-id');       %# Run mlint on the file
index = strcmp({mlintData.id},mlintIDinScript) | strcmp({mlintData.id},mlintIDinFunction);  %# Find occurrences of the warnings...
lineNumbers = [mlintData(index).line];   %#   ... and their line numbers

if isempty(lineNumbers)
    return;
end;
%# Read the lines of code from the file:

fid = fopen(fileName,'rt');
%linesOfCode = textscan(fid,'%s', 'Whitespace', '\n\r');  %# Read each line
lineNo = 0;
tline = fgetl(fid);
while ischar(tline)
    lineNo = lineNo + 1;
    linesOfCode{lineNo} = tline;
    tline = fgetl(fid);
end
fclose(fid);
%# Modify the lines of code:

%linesOfCode = linesOfCode{1};  %# Remove the outer cell array encapsulation
linesOfCode(lineNumbers) = strcat(linesOfCode(lineNumbers),';');  %# Add ';'

%# Write the lines of code back to the file:

fim = fopen(fileName,'wt');
fprintf(fim,'%s\n',linesOfCode{1:end-1});  %# Write all but the last line
fprintf(fim,'%s',linesOfCode{end});        %# Write the last line
fclose(fim);
