他们之间的区别是什么？

gulp-newer:

gulp.src(imgSrc)
  .pipe(newer(imgDest))
  .pipe(imagemin())
  .pipe(gulp.dest(imgDest));

gulp-changed:

gulp.src(SRC)
    .pipe(changed(DEST))
    // ngmin will only get the files that
    // changed since the last time it was run
    .pipe(ngmin())
    .pipe(gulp.dest(DEST));

看来gulp-change更强大,因为它提供了一个选项

hasChanged: changed.compareLastModifiedTime

gulp.task('usemin', function () {

  return gulp.src(path.src + '*.html')
    .pipe(usemin({
      assetsDir: 'src',
      css: [ minifyCss(), 'concat', rev()],
      js: [uglify(), rev()],
      images: [rev()]
    }))
    .pipe(gulp.dest(path.dist));
});

它不适用于图像.

jsbin

<input type="file" accept="image/png">

预计文件对话框仅接受png文件.但是accept="image/png"在Firefox上不起作用.我该怎么做？PS适用于Chrome.

-f, --show-name
       Show the filename in the original commit. By default the filename is shown if there is any line that came from a file with a different name, due to rename detection.

但是--show-name=off不起作用.

error: option `show-name' takes no value
usage: git blame [<options>] [<rev-opts>] [<rev>] [--] <file>

如何从输出中隐藏详细文件名？

码

import * as React from 'react';
import * as PropTypes from 'prop-types';

interface ILayoutProps {
  dir?: 'horizontal' | 'vertical'
};

const Layout: React.FunctionComponent<ILayoutProps> = (props) => {
  return (
    <div>
      {props.children}
    </div>
  );
};

Layout.defaultProps = {
  dir: 'horizontal'
};
Layout.propTypes = {
  dir: PropTypes.oneOf(['horizontal', 'vertical'])
};
export default Layout;

错误信息

  Types of property 'dir' are incompatible.
    Type 'Requireable<string>' is not assignable to type 'Validator<"horizontal" | "vertical" …
