Just to help others that may try to install this language definition copy this xml file into
C:\Users\[user]\AppData\Roaming\Notepad++\userDefineLang.xml

after copying to the location mentioned (C:\Users[user]\AppData\Roaming\Notepad++\userDefineLang.xml), and restarting notepad++, I don't see the language Dockerfile in the D section. any ideas?

User defined Languages are not sorted into subcategories but appended at the bottom. You should see Dockerfile in Language. Look at the last few entries in Language.

pkjaer commented Mar 1, 2019

I also had to manually import the file afterwards, by selecting Language | Define your language... and then clicking Import and choosing the userDefineLang_Dockerfile.xml file. After restarting Notepad++ it showed up at the bottom of the Language menu.

It would be nice if this feature could be simplified to just putting the XML file in the directory and have it pick it up automatically :)

Shouldn't SHELL be a keyword as well?

Using NPP 7.7.1, I have placed the file under C:\Users[user]\AppData\Roaming\Notepad++\userDefineLangs folder. Dockerfile entry showing automatically after NPP restart.

After importing the file in npp I had to restart it. Then Dockerfile was available from the Language dropdown menu.

This sucks if you have a dark theme (white background for all lines of text)

C:\Users\[user]\AppData\Roaming\Notepad++\userDefineLang.xml is wrong if using Notepad++ V7.7.1

C:\Users\[user]\AppData\Roaming\Notepad++\userDefineLangs\userDefineLang_Dockerfile.xml is working.

I like your idea but based on the recommendations here (notepad-plus-plus/notepad-plus-plus#2662) I gave it another crack at being more theme friendly. I ran through the default themes and it works reasonably well for most of them. The light gray for comments isn't amazing in some, particularly the hellokitty theme, but who uses those themes anyways? ;)

FWIW, I made the following changes:

  • Edited the colors to more closely match other Notepad++ built-in languages (like bash)
  • Added 2nd and 3rd Keyword Lists for variables and known double-hyphen options
  • Changed comments to be forced to beginning of line
  • Added Escape to Delimiter 1
  • Added single quote to Delimiter 1
  • Added Operators 1 and allowed Keywords 2 to nest in Delimiter 1

This sucks if you have a dark theme (white background for all lines of text)

Another solution: Notepad++ syntax highlighting for Dockerfiles (Dark version)

Does someone know how to make Notepad++ automatically assign this theme to all files labelled Dockerfile? I have to manually select Language > Dockerfile each time I open a file, the highlighting is not applied automatically.

I know this is old, but as the question was never answered I'll answer it for future searchers like myself who come across it

Notepad++ uses extensions to automatically determine what Language to use, as Dockerfile has no extension, to my knowledge, it's beyond the scope of Notepad++ to be able to recognize it

  • Changed comments to be forced to beginning of line

I'm curious as to why this was done? As it is now comments are only colored correctly if they follow a new line & start at position 0... Which is in no way required in Dockerfile... Maybe it was at the time, I'm not sure, I just know it currently isn't because they often are between things in the Dockerfiles I've worked with with no opening space & are sometimes indented. I'm not sure if they can be used at the end of a line like in YAML, as I haven't seen that so far. Is that the intent?
