Hello
I have been searching for some SPICE syntax highighting on the Internet
but I couldn't find anything close to my needs, I have tried Kate's but
I find it very lacking, so I decided to make my own. I also slightly
modified the kate.xml color scheme to fit the new requirements and the
result is pretty close to what I had in mind. If these are useful to
others, too, then here they are, attached. Bear in mind, though, that up
until a week or two ago I never knew what PCRE means or does, so this
will probably stir up some laughing. I also wanted something more
complicated, but I think I was just plain greedy and overlooked my
current knowledge of PCRE, so I gave up in the favor of the current one.
So, here they are, not imposing but merely presenting an option.
Honestly, I don't know what others might think about this but, if it's
working... try it and decide. I use Linux Mint 14 with Xfce, so I have
gedit 2.30.4 by default, but I doubt there are any problems with other
versions.

<!-- ***************************************************************************
This is meant to be a syntax highlighting *.lang file working for gedit or other text editors usin this sort of filetype. The reference is LTspice, almost exclusively, but the program is compatible with SPICE3 syntax or with many other flavours of SPICE.
LTspice can be set to have tabs or fixed font, but the color scheme is a very simple one: dark-green for comments, ref for concatenated line, blue for any dot-command and black for the rest. While this doesn't put strain on the eyes color-wise, it does have a tendency to make following certain aspects a tad harder, such as parameters in a large .param block or trying to find a .subckt in a netlist.
The methods used here are simple enough not to make everything look like a rainbow but, at the same time, to not be too simple, while trying to emphasize some key words to make editing of netlists with a text editor easier. Thus, all ennumerated below share one colour each, common or not (configurable):
- comments and in-line comments
- elements' names, model names or attributes
- values
- dot-commands:
* parameters, functions
* simulation cards
* subcircuits and models
* other directives
- subcircuit's or model's names
