where can I find the template engine guide?

[tothewine]

is it a custom one or an existing library? I am looking for conditional templating somehting like this {{#if something#}} <button> hello</button> {{#end#}}

Hello,
for templates is used Handlebars
https://handlebarsjs.com/ on js, and additional helpers https://github.com/espocrm/espocrm/b...helper.js#L110
usage of `if` https://github.com/espocrm/espocrm/b.../date/list.tpl

FYI, Handlebars does not support conditionals {{if x=="ok" then {{x}}
out of the box, you would need to register a helper.

Espo already does that already for views : https://github.com/espocrm/espocrm/b...helper.js#L110

What would be the preferred way to add that upgrade safe to pdf template handling?

Eg : Handlebars.registerHelper('ifEqual',....)

Instead of reinventing the wheel I would suggest to add minimal conditional helper to the core client.

I have used boolean (yes/no) conditionals and foreach with success in tpl templates, my workaround was to do the logic in js. Did not know there were helpers defined for views.... Surely having proper conditionals in tpl is useful!
