node-deliedit
Node js delimited text editing library.
Node js library for editing stream of text based on delimiters.
For example:
...
<html lang="en">
...
before delimiter
<!-- startedit: html -->
in delimiter
<!-- endedit: html -->
after delimiter
...
</html>
with:
var Deliedit = require('deliedit').Deliedit;
var uppercase = function(char) { return char.toUpperCase(); };
var deliedit = new Deliedit({
delimiters: {
start: '<!-- startedit: html -->',
end: '<!-- endedit: html -->'
},
invert: false,
withDelimiters: true,
transformFunc: uppercase
});
fs.createReadStream('in.html').pipe(deliedit).pipe(process.stdout);
results in:
...
<html lang="en">
...
before delimiter
<!-- startedit: html -->
IN DELIMITER
<!-- endedit: html -->
after delimiter
...
</html>
Options
var deliedit = new Delimiter(opts);
where:
-
opts.delimiter.start - start delimiter
-
opts.delimiter.end - end delimiter
-
opts.invert - apply transformation function to inside delimiter (if false) or outside delimiter (if true)
-
opts.withDelimiters - include delimiters themselves in output
-
opts.transformFunc - transformation function: passthrough, ignorechar, uppercase available - defaults to passthrough
-
opts.transform - DEPRECATED
TODO
- Add support for some other internal transformations eg. html comment / uncomment js comment / uncomment
