matlab - 如何在 Matlab 中保存时自动删除尾随空格？

Question

我没有在 Matlab 2012b 中找到基本功能:

Remove trailing whitespaces on save.

我有同样的需求，写了一个小脚本来做一些接近的事情。将以下内容放在 MATLAB desktop shortcut 中.每当您单击快捷按钮时，它都会从编辑器中的事件文件中去除尾随空格。不如在保存时自动执行它那么好——你需要记住在保存之前按下按钮——但差不多。在 11b、12a 和 13b 上进行了测试，但在 12b 上也应该没问题。

希望对您有所帮助!

% Temp variable for shortcut. Give it an unusual name so it's unlikely to
% conflict with anything in the workspace.
shtcutwh__ = struct;

% Check that the editor is available.
if ~matlab.desktop.editor.isEditorAvailable
    return
end

% Check that a document exists.
shtcutwh__.activeDoc = matlab.desktop.editor.getActive;
if isempty(shtcutwh__.activeDoc)
    return
end

% Get the current text.
shtcutwh__.txt = shtcutwh__.activeDoc.Text;

% Remove trailing whitespace from each line.
shtcutwh__.lines = deblank(regexp(shtcutwh__.txt,'[^\n]*(\n)|[^\n]*$', 'match'));

% Reconcatenate lines.
shtcutwh__.addNewline = @(x)sprintf('%s\n',x);
shtcutwh__.lines = cellfun(shtcutwh__.addNewline, shtcutwh__.lines, 'UniformOutput', false);
shtcutwh__.newtxt = horzcat(shtcutwh__.lines{:});

% Set the current text.
shtcutwh__.activeDoc.Text = shtcutwh__.newtxt;

% Delete temp variable.
clear shtcutwh__
