How to edit a lexer

[sl23]

I am using the Rainmeter lexer for INI files, but am wanting to change how it shows a Section. I really don't know anything about adjusting lexers though.
EG, currently, the Rainmeter lexer shows a Section in one of two ways.
1. A section named like this: [MySectionName] shows correctly, nicely highlighted easy to see when scanning through a file.
2. But, a section name like this: [My Section Name] or with any symbols in like this: [My-Section.Name] causes it to display as normal text with highlighted brackets and not in bold.

The lexer I used to use for INI files works better and always shows the Section name bold and highlighted.
Is there any way to adjust the Rainmeter lexer without affecting the rest of the highlighting options/settings?

Thanks

1. I fixed the Rainmeter lexer, it's updated in addons-manager.
changed regex for sections to simple: ^\[.+\]$

2. how to edit --

Oh that's great thanks for that!

Hi Alexey, this has been working perfectly, until today I noticed that single words no longer show in bold or highlighted as they originally did. Sort of the opposite of what I was getting in the first post.
Would you be able to adjust to fix that please.

EDIT: No worries, there was a space after the closed square bracket! Sorry.

you are right, I fixed this regex again. to allow trailing spaces. updated the lexer.

Ah ok thanks for the fix!

Hi Alexey,
I just updated the plugins using the built in updater and now the Rainmeter lexer has reverted back to the problem mentioned in the OP, I then copied the lexers back as I had changed the colours for syntax highlighting, but it didn't fix the issue. What is the cause and can it be solved once and for all or will it do this every time I update the plugins?

Thank you for your help.

EDIT: It's ok, I reinstalled using the Addons Manager and it's fixed it.

Actually, there is also one enhancement that would help:
Similar to the Section names in the OP, keys do not keep their highlighting if they have spaces and/or symbols.
So this works ok: MouseOverAction=....
But this does not: Mouse Over.Action=....
The reason for it is that INI files are useful for note taking. I use INI for everything where notes are required. Not comments btw, but separate files for note taking. So having spaces/symbols is often helpful here.

Here's an example of note taking:

Minimum= NVIDIA GeForce GT 1050 4GB / AMD Radeon RX 550 4GB
Recommended= NVIDIA GeForce GTX 1660 6GB / AMD Radeon RX 5500 8GB (with “Force maximum clocks” enabled) / Adreno
Optimal= NVIDIA Geforce RTX 3060 12GB / AMD Radeon RX 6700 10GB (with “Force maximum clocks” enabled)
Integrated Graphics (Minimum)= Intel UHD Graphics 730 / AMD Radeon Vega 3
Integrated Graphics (Recommended)= Intel Iris Xe Graphics / AMD Radeon 680M / Qualcomm Adreno 740 / ARM Mali G720

The Keys of the last two lines aren't coloured the same as the first three lines of Keys.

FR: Please could you add that to the Rainmeter lexer.
Thank you.
