I previously said,
[I’ll] give it a try
This is what I came up with:
INSTALLATION
Follow the instructions
https://community.notepad-plus-plus.org/topic/23039/faq-desk-how-to-install-and-run-a-script-in-pythonscript
to install PythonScript Plugin and save this script as SelectUDLBasedOnShebang.py
You will want to follow the “Starutp script” instructions in that FAQ as well, with the following two linesimport SelectUDLBasedOnShebang
selectUDLBasedOnShebang = SelectUDLBasedOnShebang.SelectUDLBasedOnShebang()
CONFIGURE:
Go to the line with “CONFIG =” and edit the contents
the extension should include the dot in the quotes
the firstLineText is the text that should match the “shebang” line (the first line of your file)
the NameOfUDL must match the name of your UDL exactly
Save
Run the script (Plugins > Python Script > Scripts > SelectUDLBasedOnShebang) or restart Notepad++
SCRIPT: SelectUDLBasedOnShebang.py
# encoding=utf-8
"""in response to https://community.notepad-plus-plus.org/topic/24921/alternative-method-of-udl-association-that-file-suffix-possible
If the extension is right, and the shebang line is right, set to a specific UDL
INSTALLATION
1. Follow the instructions https://community.notepad-plus-plus.org/topic/23039/faq-desk-how-to-install-and-run-a-script-in-pythonscript
to install PythonScript Plugin and save this script as `SelectUDLBasedOnShebang.py`
2. You will want to follow the "Starutp script" instructions in that FAQ as well, with the following two lines
import SelectUDLBasedOnShebang
selectUDLBasedOnShebang = SelectUDLBasedOnShebang.SelectUDLBasedOnShebang()
CONFIGURE:
Go to the line with "CONFIG =" and edit the contents
- the extension should include the dot in the quotes
- the firstLineText is the text that should match the "shebang" line (the first line of your file)
- the NameOfUDL must match the name of your UDL exactly
Save
Run the script (Plugins > Python Script > Scripts > SelectUDLBasedOnShebang)
From now on (including after restart), anytime you activate the buffer of a file
ending with a known extension (one of the extensions in CONFIG), it will
look at the first line, and if the first line exactly matches one of the
firstLineText strings in the CONFIG table, then it will activate the UDL
that has exactly the NameOfUdl
