## Description

Child Themes are used to avoid overwriting your customizations. But if you preserve
a file in a child theme, then you maybe preserve a security risk. After an update
from the parent theme you always should check the changes and maybe add them to 
your child theme. This plugin helps you keeping track of these changes in the parent
theme.

For full usage of the plugin your parent theme has to define the version of the 
template file in the header of the PHP file with an additional @version info.

For example: `@version 1.0.0`

If this is the case you will see a warning if the version of the parent theme file
is higher than your child theme file. And you can see the differences between the
parent theme file and the child theme file per wp_text_diff()-function like in revisions.

Some posts about this plugin:

 * [KrautPress](https://krautpress.de/2016/child-theme-dilemma/) (German)
 * [WP Tavern](https://wptavern.com/child-theme-check-plugin-helps-wordpress-users-navigate-parent-theme-updates)(
   English)

   English)
 * [Elmastudio](http://www.elmastudio.de/wordpress-plugin-tipp-child-theme-check/)(
   German)

These themes from [Elmastudio](http://www.elmastudio.de/en/) are already using the
@version info in the header:

 * Uku
 * Uku Light
 * Weta
 * Pukeko
 * Zeitreise
 * Werkstatt
 * Neubau
 * Hawea

Please spread the word and if you are a theme developer, please add this to your
themes too! Thanks 🙂

### I just get the error: Parent theme is missing version keyword.

For full usage of the plugin your parent theme has to define the version of the 
template file in the header of the PHP file with an additional @version info.

For example: `@version 1.0.0`

If this is the case you will see a warning if the version of the parent theme file
is higher than your child theme file. And you can see the differences between the

### 󠀁[Diff is Legit](https://wordpress.org/support/topic/diff-is-legit/)󠁿

 [exius](https://profiles.wordpress.org/exius/) 2 juillet 2020

Diff works as advertised. It highlights changes to lines of code inside my child-
theme files as compared to the parent theme files. Since I’m using a premium theme,
I don’t have control over how the theme is written, so the @version detection feature
will doubtfully be useful in this case since the parent theme isn’t using that on
top of all their pages. They are however using the @since tag for almost every function.
That seems complicated to track. Diff is already highlighting the differences between
lines of code, so @since might not be too useful either.

I was bored to verify if my child themes were up to date and this plugin is a great
tool to see in a glimps if you have to rework your child theme.

Thank you Thorsten et.al for this very useful plugin. I think it’s a fantastic idea
to check for a version header and this plugin is a good reminder of developing with
a useful standard.
