I'm trying to output the following from within a liquid template:
{{ example }}
Obviously, Liquid sees this as a variable named example and tries to do substitution. I'm trying to find out how I can output the actual braces.
So far, I've found one method that works, but it's incredibly ugly:
{{ '{example'|prepend:'{' }}}}
Yeah, told you it was gross.
Here are other things I've tried:
{{{ example }}} # outputs '}'
{{{{ example }}}} # outputs '}}'
\{\{ example \}\} # outputs '\{\{ example \}\}'
Any advice here?
You can also use raw:
{% raw %}
...lots of liquid code goes here and it doesn't get interpreted...
{% endraw %}
What about using the numeric HTML entities { and } for { and } respectively - presumably this is to be output as HTML?
EDIT: Forgive me, I'm not too familiar with liquid (so this might be very wrong), but can you assign your {{ example }} special value to a variable and output that? May be something like:
{% assign special = '{{ example }}' %}
{{ special }}
This is the only thing that worked from me. Lifted from here:
{{ "{{ this " }}}}
I needed this because I wanted to reference the site global variable from inside a mustache template.
I wanted to have both curly brackets AND angle brackets when formatting a fenced code block, so I ended up with the following pattern:
{% capture code %}{% raw %}line 1
line 2
line 3
{% endraw %}{% endcapture %}
<pre><code>{{ code | replace: "<", "<" | replace: ">", ">" }}</code></pre>
You can escape the HTML, for example in a {{var}} you can use \{\{var\}\}, so that way luquid don't process it.

I have some trouble by replacing a substring with liquid transformation.
This is my output where I want to replace the forward slash by a dot.
"ProductName": "2x19/ display in control room"
My code looks like this:
[
{% for Order_var in content[0].ListOfSmsOrderEntrySales.OrderEntry-Orders.ListOfOrderEntry-LineItems.OrderEntry-LineItems %}
{
"Id":"{{Order_var.Id}}",
"PartNumber":"{{Order_var.PartNumber}}",
"Product":"{{Order_var.Product}}",
"ProductDefTypeCode":"{{Order_var.ProductDefTypeCode}}",
"ProductId":"{{Order_var.ProductId}}",
"ProductIntegrationId":"{{Order_var.ProductIntegrationId}}",
"NetPrice":"{{Order_var.NetPrice}}",
"ProductName":"{{Order_var.Description2 | replace: '/', '.' }}",
},
{% endfor %}
]
I still get the same ouput with no replacement. Any idea? Would be grateful
Cheers
Please use Replace but not replace in your liquid template. The document of liquid shows {{ "Take my protein pills and put my helmet on" | replace: "my", "your" }}, but according to test, we need to use upper case Replace in liquid template.
I've got a regex working that I'm unable to use with Twig match. Basically, I need to confirm if a message contains "#firstname lastname " in it anywhere. The message can have returns, multiple matches, etc. The regex must match the entire message as long as "#firstname lastname " exists in it somewhere.
This is the regex I got working here: https://regexr.com/
/.+?(?=#)#[A-z]+ [A-z]+ (.*)/gs
And it worked for: This is a bunch of text surrounding #firstname lastname and so forth
What I tried:
{%- set action -%}
Twig needs to handle the set in this format #firstname lastname
for what I need to work
{%- endset -%}
And:
{% set regex = '/.+?(?=#)#[A-z]+ [A-z]+ (.*)/gs' %}
Then:
{% if action matches regex %}
Working
{% else %}
Not working
{% endif %}
What I get is: Not Working
There is no space between lastname and for, also g is not a valid modifier in PHP
{% set regex = '/.+?(?=#)#[A-z]+ [A-z]+(.*)/s' %}

I am building a very basic template engine. My template is super simple:
...html code before...
{{ foreach apples }}
... html code to be repeated {{apple}} ...
{{ endforeach }}
{{ foreach oranges }}
... html code to be repeated {{orange}} ...
{{ endforeach }}
...html code after ...
My goal is to get the first foreach (apples) and I've arrived here: https://regex101.com/r/cD5gY4/2
Does anybody have an idea about how I could stop to the end of the first loop instead of capturing both?
.* is greedy, make it non-greedy by adding a quantifier like ? to it. Try this:
{{\s*foreach ([a-z]+)\s*}}(.*?)({{\s*endforeach\s*}})
REGEX101
so I got my hands on regular expressions and tried to match the outer {% tag xyz %}{% endtag %} tags of the following text using regular expressions:
{% tag xyz %}
{% tag abc %}
{% endtag %}
{% endtag %}
My regular expression looks as follows and works so far:
({%)\s*(tag)([^%}]*?)(?:\s*(?:(%})((?:(?:[^{%]*?)|(?R))*)(?:({%)\s*(end\2)\s*(%}))))
But whenever the text inside of the matching tags contains a single { or % sign, the regex won't work as expected. I think it's because of the character classes that may match {% but also { or % as single characters too. I tried a lot and ended up with try and error but without success.
Any help on that issue?
I setup two regex101 links for you to show the issue:
works: https://regex101.com/r/qH0rI5/1
does not work: https://regex101.com/r/qH0rI5/2
Any help is really appreciated!
Try to to replace [^{%] with (?:(?!{%).) and add the s (PCRE_DOTALL) flag:
This would allow { that are not followed by % in between by using a negative lookahead.
Test your updated pattern or here another start to try with:
/{% tag \w+ %}(?:(?:(?!{%).)|(?0))*{% endtag %}/gs

I'm working on a script helping me catching all my localized strings in my project and I'm stuck on a RegEx.
In the following string {{ translateAttr title="button.add_user.title" data-disable-with="button.add_user.disabled" }} I'd like to be able to catch "button.add_user.title" and "button.add_user.disabled" because my curly braces starts with translateAttr attribute.
So far, I've come with this rule \{{2}translateAttr .*=(['"])(.+?)(?=(?<!\\)\1)\1 ?}{2} but as you could see here http://lumadis.be/regex/test_regex.php?id=2362 it is not matching all the occurrences.
A little help here would be much appreciated.
EDIT: Patterns I'd like the regex to match too
{{ translateAttr title="button with \"escaped quotes\" here" data-disable-with='button with single quotes' }}
{{ translateAttr title="want this with ' single quote" "but not this one" }}
EDIT2 : Patterns I don't like to match
{{ title="because no translateAttr" }}
{{ translateAttr "because no something= attribute before" }}
Thanks
Use the below regex which uses the PCRE verb (*SKIP)(*F)
^(?!.*?\{{2}\h*translateAttr).*(*SKIP)(*F)|=(["'])((?:\\\1|(?!\1).)*)\1
