pug-load
The pug loader is responsible for loading the depenendencies of a given pug file. It adds fullPath
and str
properties to every Include
and Extends
node. It also adds an ast
property to any Include
nodes that are loading pug and any Extends
nodes. It then recursively loads the dependencies of any of those included files.
Installation
npm install pug-load
Usage
var load = require('pug-load');
load(ast, options)
load.string(str, filename, options)
load.file(filename, options)
Loads all dependencies of the Pug AST. load.string
and load.file
are syntactic sugar that parses the string or file instead of you doing it yourself.
options
may contain the following properties:
lex
(function): (required) the lexer usedparse
(function): (required) the parser usedresolve
(function): a function used to overrideload.resolve
. Defaults toload.resolve
.read
(function): a function used to overrideload.read
. Defaults toload.read
.basedir
(string): the base directory of absolute inclusion. This is required when absolute inclusion (file name starts with'/'
) is used. Defaults to undefined.
The options
object is passed to load.resolve
and load.read
, or equivalently options.resolve
and options.read
.
load.resolve(filename, source, options)
Callback used by pug-load
to resolve the full path of an included or extended file given the path of the source file.
filename
is the included file. source
is the name of the parent file that includes filename
.
This function is not meant to be called from outside of pug-load
, but rather for you to override.
load.read(filename, options)
Callback used by pug-load
to return the contents of a file.
filename
is the file to read.
This function is not meant to be called from outside of pug-load
, but rather for you to override.
load.validateOptions(options)
Callback used pug-load
to ensure the options object is valid. If your overridden load.resolve
or load.read
uses a different options
scheme, you will need to override this function as well.
This function is not meant to be called from outside of pug-load
, but rather for you to override.
Example
var fs = require('fs');
var lex = require('pug-lexer');
var parse = require('pug-parser');
var load = require('pug-load');
// you can do everything very manually
var str = fs.readFileSync('bar.pug', 'utf8');
var ast = load(parse(lex(str, 'bar.pug'), 'bar.pug'), {
lex: lex,
parse: parse,
resolve: function (filename, source, options) {
console.log('"' + filename + '" file requested from "' + source + '".');
return load.resolve(filename, source, options);
}
});
// or you can do all that in just two steps
var str = fs.readFileSync('bar.pug', 'utf8');
var ast = load.string(str, 'bar.pug', {
lex: lex,
parse: parse,
resolve: function (filename, source, options) {
console.log('"' + filename + '" file requested from "' + source + '".');
return load.resolve(filename, source, options);
}
});
// or you can do all that in only one step
var ast = load.file('bar.pug', {
lex: lex,
parse: parse,
resolve: function (filename, source, options) {
console.log('"' + filename + '" file requested from "' + source + '".');
return load.resolve(filename, source, options);
}
});
