有没有一种方法可以一次修复所有的matlabmlint消息?

注: 此答案使用函数 MLINT ,这在较新版本的MATLAB中不再推荐。更新的函数 CHECKCODE 下面的代码仍然可以工作,只需将对MLINT的调用替换为对这个较新函数的调用。

一般来说 姆林特 具体的 姆林特 警告。

junk.m :

a = 1
b = 2;
c = 'a'
d = [1 2 3]
e = 'hello';

第一行、第三行和第四行将为您提供 姆林特 警告消息“用分号终止语句以抑制输出(在脚本中)。”。使用函数形式 姆林特 ,我们可以在文件中找到发生此警告的行。然后,我们可以从文件中读取所有代码行,在出现警告的行的末尾添加分号,然后将代码行写回文件。下面是执行此操作的代码:

%# Find the lines where a given mlint warning occurs:

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

%# Read the lines of code from the file:

fid = fopen(fileName,'rt');
linesOfCode = textscan(fid,'%s','Delimiter',char(10));  %# Read each line
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:

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

现在是文件 垃圾。m 每行末尾都应该有分号。如果需要,可以将上述代码放在函数中,以便可以轻松地在继承代码的每个文件上运行它。

为了以一种通用的方式解决所有可用的autofix操作的这个问题,我们必须求助于可怕的没有文档的java方法。实施 mlint checkcode )用途 mlintmex 文本 $(matlabroot)/bin/$(arch)/mlint )

因此,我们必须回到编辑器本身使用的java实现。注意:下面是R2013a的未记录代码。

%// Get the java component for the active matlab editor
ed = matlab.desktop.editor.getActive().JavaEditor.getTextComponent();
%// Get the java representation of all mlint messages
msgs = com.mathworks.widgets.text.mcode.MLint.getMessages(ed.getText(),ed.getFilename())

%// Loop through all messages and apply the autofix, if it exits 
%// Iterate backwards to try to prevent changing the location of subsequent
%// fixes... but two nearby fixes could still mess each other up.
for i = msgs.size-1:-1:0
  if msgs.get(i).hasAutoFix()
    com.mathworks.widgets.text.mcode.analyzer.CodeAnalyzerUtils.applyAutoFixes(ed,msgs.get(i).getAutoFixChanges);
  end
end

啊哈! 您可以让mlint二进制文件返回带有 -fix 标记。。。这适用于内置 校验码

>> checkcode(matlab.desktop.editor.getActiveFilename(),'-fix')
L 2 (C 3): Terminate statement with semicolon to suppress output (in functions).  (CAN FIX)
----FIX MESSAGE  <Add a semicolon.>
----CHANGE MESSAGE L 2 (C 13);  L 2 (C 12):   <;>
L 30 (C 52-53): Input argument 'in' might be unused. If this is OK, consider replacing it by ~.  (CAN FIX)
----FIX MESSAGE  <Replace name by ~.>
----CHANGE MESSAGE L 30 (C 52);  L 30 (C 53):   <~>

在分配给结构时,这也揭示了新结构的用途 fix 场 @High Performance Mark @gnovice 的 answer FIX MESSAGE 当消息是 CHANGE MESSAGE .

matlab.desktop.editor 公共(!)获取活动文档的API( getActive )并在屏幕上使用getter和setter Text

function str = applyAutoFixes(filepath)

msgs = checkcode(filepath,'-fix');

fid = fopen(filepath,'rt');
iiLine = 1;
lines = cell(0);
line = fgets(fid);
while ischar(line)
    lines{iiLine} = line;
    iiLine = iiLine+1;
    line = fgets(fid);
end
fclose(fid);

pos = [0 cumsum(cellfun('length',lines))];
str = [lines{:}];

fixes = msgs([msgs.fix] == 4);
%// Iterate backwards to try to prevent changing the indexing of 'str'
%// Note that two changes could still conflict with eachother. You could check
%// for this, or iteratively run mlint and fix one problem at a time.
for fix = fliplr(fixes(:)')
    %'// fix.column is a 2x2 - not sure what the second column is used for
    change_start = pos(fix.line(1)) + fix.column(1,1);
    change_end   = pos(fix.line(2)) + fix.column(2,1);

    if change_start >= change_end
        %// Seems to be an insertion
        str = [str(1:change_start) fix.message str(change_start+1:end)];
    else
        %// Seems to be a replacement
        str = [str(1:change_start-1) fix.message str(change_end+1:end)];
    end
end
