I have template-like file, with some simple HTML in it.
<html>
<head>
<meta charset="utf-8">
<title>stackoverflow.com</title>
<link rel="stylesheet" href="/css/master.css" type="text/css" media="screen" title="no title" charset="utf-8">
</head>
<body id="container">
<table border="0" cellspacing="5" cellpadding="5">
<tr>
<th>Field 1 Label</th>
<th>Field 2 Label</th>
<th>Field 3 Label</th>
</tr>
<!-- ...dynamically generated content from other file should go here... -->
<!-- ...instead of this template tag... -->
${sqlite_html_output} <!-- this is a placeholder I want to use -->
</table>
</body>
</html>
The file I want to render into this template, will be the output of sqlite query contained in the following function:
function generate_report() {
sqlite3 -batch database.db <<- "end_of_message"
.mode html
.output o.html # <-- this is the name of generated output file
select field1,field2,field3 from tbl;
end_of_message
#..here I want to use `sed` to embed content of o.html file, into my template
}
So in my generate_report function, I want to use sed to render that o.html
file, into my template, in place of that ${sqlite_html_output} template-tag placeholder.
Would that be possible?
Try this:
sed '/\${sqlite_html_output}/{r o.html
d;}' template_file
It should search for a line matching ${sqlite_html_output} and, when matching it, insert text read from o.html then delete content of line (i.e. ${sqlite_html_output} <!-- this is a placeholder I want to use --> in your example).
Line break is mandatory.

I know about existance of layout dialect for Thymeleaf (https://github.com/ultraq/thymeleaf-layout-dialect), but before jumping into said dialect dating pre thymeleaf 3, I wanted to explore newer fragment expressions (introduced in TL3).
So as per docs - I can define base.html that will work almost the same way that the layout dialect allows fragments to be managed.
base.html:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head th:fragment="base(title, links, content)">
<title th:replace="${title}"></title>
<link rel="stylesheet" type="text/css" media="all" href="/css/main.css" />
<th:block th:replace="${links}"></th:block>
</head>
<body>
<header th:replace="~{header :: header}"></header>
<div th:replace="${content}"></div>
<footer th:replace="~{footer::footer}"></footer>
</body>
</html>
...but then when I use this in my home.html:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head th:replace="base::base(~{::title}, ~{::link}, ~{::content})">
<title th:text="#{home.title}"></title>
<link rel="stylesheet" th:href="test">
<link rel="stylesheet" th:href="test1">
<link rel="stylesheet" th:href="test2">
</head>
<body>
<div th:fragment="content">
<span>TEST CONTENT</span>
</div>
</body>
</html>
...it acts like home.html only evaluates itself and arguments it passes to base.html because this is product:
<!DOCTYPE html>
<html>
<head>
<title>My home page</title>
<link rel="stylesheet" type="text/css" media="all" href="/css/main.css" />
<link rel="stylesheet" href="test"><link rel="stylesheet" href="test1"><link rel="stylesheet" href="test2">
</head>
<body>
<div>
<span>TEST CONTENT</span>
</div>
</body>
</html>
As you can see, title is evaluated in home.html and passed to base.html, same goes for 3 links I provided in home.html. Also content gets passed and placed in proper place. What is missing? Everything that is not argument of base.html fragment. Thymeleaf ignores evaluating my header and footer and just removes them.
Let me just note that If I were to place header/footer in home.html inside content they will be evaluated like they should - from header.html with selector header: "~{header :: header}".
Am I missing something crucial as to how this whole thing is supposed to work? What's the point of being able to define fragments that will work as layout if they can't evaluate themselves and need everything passed from "child file (caller)"?
It seems to me you mixed fragments and replacements together. The head replacement works well because you declared it correctly. But why did you declare a th:replace attribute in base.html like
<header th:replace="~{header :: header}"></header>? It is not within a fragment, not a parameter, therefore it must be replaced from somewhere.
As far as I understand you expect fragments in base.html and replacements in home.html. Then make both the header and footer fragments and declare corresponding th:replace tags in home.html.
<div th:replace="${content}"></div>
This also doesn't work because it is not within a th:fragment tag.
The bottom line: fix the hierarchy of tags and the logic of replacement.
Like Xaltotun pointed out - I needed to fix my stuff.
I've placed base(args...) in header so my passed fragments werent visible in body, thus everything failed.
Let me just add some code:
Layout.html:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" th:fragment="layout(content, title, meta)">
<head>
<title th:text="${title}">Default Title</title>
<link rel="stylesheet" type="text/css" media="all" href="/css/style.css" />
<th:block th:replace="${meta}" />
</head>
<body>
<div class="viewport">
<header class="website-header">
...
</header>
<div th:replace="${content}"></div>
<th:block th:replace="staticContentTemplate :: testFragment" />
<footer class="website-footer">
...
</footer>
</div>
</body>
</html>
Home.html:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" th:replace="layout::layout(~{::content}, #{home.title}, ~{::meta})">
<head>
<th:block th:fragment="meta">
<link rel="stylesheet" th:href="test">
</th:block>
</head>
<body>
<div th:fragment="content">
<span>TEST CONTENT</span>
</div>
</body>
</html>
Result is as expected:
Home.html provides title, content and meta.
Layout.html gives everything else, and also copies additional template from different source staticContentTemplate :: testFragment
Tip for others: notice that I placed args in layout in this order - content since its always present, title that can be optional and meta that might not be needed - this allows us to call layout with just content: layout(~{::content}) (shorter = better).
It's weird that my shell script in website show the whole source code, not the html that I want.
My script is:
#!/bin/sh
echo "Content-type: text/html"
echo ""
cat << EOF
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<title>test</title>
<link type="text/css" href="../jquery/css/redmond/jquery-ui-custom.min.css" rel="stylesheet">
<script type="text/javascript" src="../jquery/js/jquery.min.js"></script>
<script type="text/javascript" src="../jquery/js/jquery-ui-custom.min.js"></script>
<script type="text/javascript">
//<![CDATA[
if(verifiedUser == "")
window.top.location.href = "/";
//]]>
</script>
</head>
<body>
<table align="center">
<tr><td align="right">Product Name</td><td align="left">

<tr><td align="right">Hardware Version</td><td align="left">

<tr><td align="right">Firmware Version</td><td align="left">

</table>
</body>
</html>
EOF
and what the .cgi file show is just that code!
My cgi file is in the same directory of the html files, because the main directory is in /mnt, so not put in /home/www/cgi-bin/ as usual.
What's the reasonable problem can cause this situation?
Any advice appreciated!
AFAIK, the separator between header section & the html data should be a blank line in CRLF format.
Try this:
echo -e "Content-type: text/html\r"
echo -e "\r"
cat << 'EOF'
---remaining HTML data---
EOF
Note: I have also changed cat << EOF to cat << 'EOF' to prevent any variable expansion. Revert it if variable/command expansion is needed.
#Barmar has the right idea - Your server is very likely not configured to run those files, but rather send the file directly to the client. So it's a configuration issue, not a programming one.
I am using laravel 4 for a project. Is there any way I can specify what js files I want to load for a certain view. Right now I am lumping all in one file.
When I use codeigniter, to load specific js files, i use a library to generate the script tags and echo them at the footer. something as below
$this->data['js'] = $this->js_lib->generate('jquery');
Then in my view
<?= $js ?>
Any idea how to do this in laravel?
Main Layout
main.blade.php
#include('includes.header')
<body>
<!-- main content -->
<div id="main_wrapper">
<div class="page_content">
#yield('content')
</div>
</div>
#include('includes.footer')
</body>
header.blade.php
<head>
<meta charset="UTF-8">
<title>My Page</title>
<meta name="viewport" content="initial-scale=1.0,maximum-scale=1.0,user-scalable=no">
<!-- common styles -->
<link rel="stylesheet" href="{{ asset('assets/bootstrap.css') }}">
<!-- page specific styles -->
#yield('pagespecificstyles')
</head>
footer.blade.php
<footer>
<!-- common scripts -->
<script src="{{ asset('assets/js/jquery.min.js') }}"></script>
<!-- page specific scripts -->
#yield('pagespecificscripts')
mypage.blade.php
#extends('layouts.main')
#section('pagespecificstyles')
<!-- flot charts css-->
<link rel="stylesheet" href="{{ asset('assets/lib/owl-carousel/flot.css') }}">
#stop
#section('content')
<div class="container">

Stacks
Blade allows you to push to named stacks which can be rendered somewhere else in another view or layout. This can be particularly useful for specifying any JavaScript libraries required by your child views:
#push('scripts')
<script src="/example.js"></script>
#endpush
You may push to a stack as many times as needed. To render the complete stack contents, pass the name of the stack to the #stack directive:
<!-- Component Contents -->
#stack('scripts')
</body>
https://laravel.com/docs/5.7/blade#stacks
I know asked a while ago but for the benefit of others who may stumble here! One option is also in your layout to define additional sections, e.g.
#yield('css') <!-- In the head -->
#yield('js') <!-- Before the </body> tag -->
Then in your views
#extends('some.layout')
#section('css')
#include('js/dependencies/some/js/dependency/css.css')
#append
<!-- So in case these dependencies are used elsewhere you're not repeating your script or link tags over and over -->
#section('js')
#include('js/dependencies/some/js/dependency/js.js')
#include('js/dependencies/some/js/dependency/js2.js')
#append
#section('content')
Your actual content
#endsection
Just have a 'partials' view folder - and include whatever script you want in each view.
So in your view;
<body>
// Your main content here
// Other JS files you want in all views
#include('partials.analytics.blade.php')
#include('partials.googlemaps')
#include('partials.some_other_js_file')
</body>
Then have /views/partials/analytics.blade.php
<script>
// Your JS analytics script here
</script>
and just repeat for each 'script'
You may add the following code in your app.blade file
#stack('scripts')
and then you can use the jquery on page
#push('scripts')
<script type="text/javascript">
///Js code
</script>
#endpush
I am trying to add a full html page into ckeditor for some editing via js.
Specifically, I execute the command
oEditor.insertHtml("<html><head><title>Hello</title></head><body><div>hello</div></body></html>");
But the result I get is the following:
<p>
<html>
<head>
<title></title>
</head>
<body>
</body>
</html>
</p>
<p>
<title></title>
</p>
<div>
hello</div>
The mode I use is:
config.fullPage = true
I tried also with fullPage = false, but not success.
Is there any way to insert to ckeditor a full html page?
Thanks a lot in advance!!
The insert* methods append the data to the editor contents, but if you want to replace the whole content then you must use setData.
I am focused on the wrong layer of abstraction here, but can't figure out where.
I have this file views/pages/overview.html.erb
<%= stylesheet_link_tag "cust/coderay"%>
<h1>Overview</h1>
<hr>
Here's my code test:
<%= html = CodeRay.scan("puts 'Hello, world!'", :ruby).div(:line_numbers => :table)%>
<hr>
Back <%=link_to "home", "home"%>.
<hr>
It took <%="%.3f" %(Time.now-#start_time)%> seconds to generate this page.
To my surprise, the pages renders like so:
When I view source on the page I get:
<!DOCTYPE html>
<html>
<head>
<title>Dash</title>
<link href="/assets/application-all.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/all/pages.css?body=1" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>
<script src="/assets/pages.js?body=1" type="text/javascript"></script>

</head>
<body>
<h1>Overview</h1>
<hr>
Here's my code test:
<table class="CodeRay"><tr>
<td class="line-numbers" title="double click to toggle" ondblclick="with (this.firstChild.style) { display = (display == '') ? 'none' : '' }"><pre>
</pre></td>
<td class="code"><pre>puts <span style="background-color:hsla(0,100%,50%,0.05)"><span style="color:#710">'</span><span style="color:#D20">Hello, world!</span><span style="color:#710">'</span></span></pre></td>
</tr></table>
<hr>
Back home.
<hr>
It took 0.006 seconds to generate this page.
</body>
</html>
Why is the bracketed css displaying as inline text? What should my usage of coderay look like here?
Many thanks -
Rails escapes your HTML by default in ERB templates. You need to turn off HTML escaping like so:
<%=raw CodeRay.scan("puts 'Hello, world!'", :ruby).div(:line_numbers => :table) %>
See more at this question and these release notes.
