Utility to read the contents of a vinyl file.
/*
WARNING: This is a very naive plugin implementation
It is only meant for demonstation purposes.
For a more complete implementation, see: https://github.com/gulp-community/gulp-pug
*/
var { Transform } = require('streamx');
var pug = require('pug');
var vinylContents = require('vinyl-contents');
function gulpPug(options) {
return new Transform({
transform: function (file, cb) {
vinylContents(file, function (err, contents) {
if (err) {
return cb(err);
}
if (!contents) {
return cb();
}
file.contents = pug.compile(contents.toString(), options)();
cb(null, file);
});
},
});
}Warning: Only use this if interacting with a library that can only receive strings or buffers. This loads all streaming contents into memory which can cause unexpected results for your end-users.
Takes a Vinyl file and an error-first callback. Calls the callback with an error if one occur (or if the first argument is not a Vinyl file), or the file contents if no error occurs.
If the Vinyl contents are:
- A Buffer, will be returned directly.
- A Stream, will be buffered into a BufferList and returned.
- Empty, will be undefined.
