I am using wkhtmltopdf version 0.12.2.1 (with patched qt) to render my reactJs app! It worked fine, until I added the react-pdf-js lib to render the pdf generated inside my app. I followed the code described on react-pdf-js documentation (see https://www.npmjs.com/package/react-pdf-js) to make it work.
The pdf is rendered inside my page, and it looks pretty cool indeed. But when I try to run wkhtmltopdf again, to generate a pdf of any page of my app, the following error is returned:
desenv01#desenv01-PC:~$ wkhtmltopdf -O Landscape --print-media-type --debug-javascript http://localhost:3000/report/1 report.pdfLoading pages (1/6)
Warning: undefined:0 ReferenceError: Can't find variable: Float64Array
Warning: http://localhost:3000/assets/js/app.js:46789 SyntaxError: Parse error
Counting pages (2/6)
Resolving links (4/6)
Loading headers and footers (5/6)
Printing pages (6/6)
Done
Then, I went to my app.js to see what's on line 46789:
set href(href) {
clear.call(this);
parse.call(this, href);
},
get protocol() {
return this._scheme + ':';
},
set protocol(protocol) {
if (this._isInvalid)
return;
parse.call(this, protocol + ':', 'scheme start');
},
The error happens on the line that says parse.call(this, href);, which is part of pdf.combined.js script.
I could not find any solution online so I wondered if there is anyone who might know if I did something wrong or a way to work around it.
Thanks..
I ran into this using wkthmltopdf 12.3 and 12.4 because I have my IDE set to nag me for using var instead of let. The problem is the older Qt engine powering those versions of the program doesn't recognize new-style, ES6 keywords. Not sure if you can down-convert React. Otherwise you can try the bleeding edge versions which use a newer Qt.
I have same problem. I fixed it by modify some code that i think it is new in JS. let keyword (ES5) and template literals (ES6).
generateRandomColor= function () {
let maxVal = 0xFFFFFF; // 16777215
let randomNumber = Math.random() * maxVal;
randomNumber = Math.floor(randomNumber);
randomNumber = randomNumber.toString(16);
let randColor = randomNumber.padStart(6, 0);
return `#${randColor.toUpperCase()}`
}
I modify above code into below
generateRandomColor = function () {
var maxVal = 0xFFFFFF;
var randomNumber = Math.random() * maxVal;
randomNumber = Math.floor(randomNumber);
randomNumber = randomNumber.toString(16);
var randColor = randomNumber.padStart(6, 0);
return "#" + randColor.toUpperCase();
}
i need a batch for downloading files from a http website (http://www.rarlab.com/download.htm).
From this website i only need the most recent version for the 32bit and 64bit english
program which is always listed at the top of this website.
Problem 1: There are more than this two files for download on the website
Problem 2: The name of the file changes with every new version
How can i download these 2 files (the most recent version) without knowing the exact file name
(and without first visiting the web page to find out the file name) ??
Maybe i can use wget, curl or aria2 for that task but i don't know the parameters/options.
Can anyone help me solving this problem ?
(Please only batch solutions - no vbs, java, jscript, powershell etc.)
thank you.
Sorry, i forgot to say that i use windows 7 32bit. And i prefer batch because the script should be able to run on all windows versions without having to download extra programs or resource kits for different windows version (as of powershell which must be downloaded for windows xp etc.) - and because i only understand batch scripting.
Here's a batch + JScript hybrid script. I know you said no vbs, java, jscript, etc, but you're going to have an awfully hard time scraping HTML with pure batch. But this does meet your other criteria -- running on all Windows versions without having to rely on optional software (like powershell or .Net).* And with JScript's XMLHTTP object you don't even need a 3rd party app to fetch web content.
As for not understanding JScript, aside from a few proprietary ActiveX objects it's just like JavaScript. In case you aren't familiar with JavaScript or regular expressions, I added copious amounts of comments to help you out. Hopefully whatever I didn't bother commenting is pretty obvious what it does.
Update
The script now detects the system locale, matches it with a language on the WinRAR download page, and downloads that language release.
Anyway, save this with a .bat extension and run it as you would any other batch script.

I'm trying to optimize the CasperJS tests run.js code(https://github.com/n1k0/casperjs/blob/master/tests/run.js), so that I could understand how I can use it further to optimize further the tests that I've written. Here's the sample run.js of the CasperJS project that I was trying to optimize using ADVANCED_OPTIMIZATIONS flag to the compiler.
(https://github.com/n1k0/casperjs/blob/master/tests/run.js)
But the optimized code is as below:
phantom.d || (console.log("This script must be invoked using the casperjs executable"), phantom.c(1)); var a = require("fs"), c = require("utils").h, d = require("casper").create({g:!1}); d.options.n = d.a.get("direct") || !1; d.options.i = d.a.get("log-level") || "error"; d.m("open.location", function(b) { return!/^http/.test(b) ? c("file://%s/%s", phantom.e, b) : b }); var e = []; d.a.b.length ? e = d.a.b.filter(function(b) { return a.isFile(b) || a.isDirectory(b) }) : (d.f("No test path passed, exiting.", "RED_BAR", 80), d.c(1)); d.test.j("tests.complete", function() { this.k(true, void 0, d.a.get("xunit") || void 0) }); d.test.l.apply(d.test, e);
Obviously, this is failing as being told by the compiler (Ex: JSC_INEXISTENT_PROPERTY: Property casperLoaded never defined on phantom at line 2 character 5
if (!phantom.casperLoaded) )
Can you please guide me as to how to use the Closure Compiler, to optimize all of the JS files in the project with their dependencies, thus avoiding these errors and proceed further.
I went through the documentation for the Closure, but I wasn't able to figure out the approach needed in this case.
FYI: I was using the Closure compiler.jar
Support has been added to Closure Compiler to make it is easier to work with Common JS and AMD/require.js modules using the following compiler flags:
--transform_amd_modules
--process_common_js_modules
--common_js_entry_module
--common_js_module_path_prefix
See Experimental support for Common JS and AMD/require.js modules in Closure Compiler
