Fast-Syntax-Highlighting demo

Fast-Syntax-Highlighting demo

[Sebastian Gniazdowski]

Hello,
again so much has been added to FSH that I've decided to write.

Ideal brackets highlighting, resilient to quoting – note the sidx=...,
eidx=... lines:

http://psprint.blinkenshell.org/theme.png

That's the general demo of FSH. It shows themes, math-mode
highlighting, etc. Note that it also does assign-highlighting – the
math=... etc. lines would normally be plain white.

Demonstration of chroma architecture (it treats zsh -c specifically,
descents to -c contents), and recursivity (eval):

This normally looks like following:

That's pretty cool.  Are you saying you've got the shell colorizing 
itself?  Various editors do that of course.

Yes, brackets (three types: ( ), { }, [ ]) are detected, paired and
highlighted by the shell, by plugin zdharma/fast-syntax-highlighting.
Also, after pointing cursor at some bracket, its matched, paired
bracket is highlighted with blue background:

The point is that the code of the solution guarantees correct bracket
highlighting and pairing, no quoting can disturb it, so e.g.
constructing a pattern- or regex-hogs is much easier now, such string
will be divided into blocks delimited by ( ) and [ ] brackets ( { }
aren't used, at least by patterns, AFAIK).

I'll be sure to try that out next time I do any coding.

ZSH continues to amaze me after more than 20 years of using it!

This "add-on" ("plugin", "theme", etc.) is amazing! I keep a casual eye
on changes and progress in command line "technology", and this is one
that is immediately useful!

Thanks, Sabastian, for your work on Fast Syntax Highlighting!

Thanks, it's 3 years now of gradual extending of what's possible, in
large extent motivated by user hints. I mean, I didn't know this would
go that far, but users often mentioned what would be cool, and it
turned out to be possible. It was a long process.

Wouldn't you mind to:

1) add some "top-level" menion of secondary themes (with description that it 
is the theme to apply inside `$()`) in the documentation (both in READDME and 
`fast-theme -h`)?

===

2) add some way to load the (custom) themes from outside of FSH repo?
It would be good if, say, fast-theme will support:
 - some environment variable with additional themes location path(s)
 - "loading" themes by full path (even if that path isn't on the currently 
"known" paths)

===

3) add some "easy" way for dumping current "theme" (with all the active 
redefinitions) in ini-format (to use as the new theme).

Ok. It's a constant pain, easy but not easy to describe things queued
for README.md.

A user had a cool idea, to simply do `fast-theme ~/custom.ini`. It can
use shorthand `fast-theme XDG:custom`, where XDG ==
${XDG_CONFIG_HOME:-$HOME/.config}/fsh. Full description of how this
resolved (today) is at:

https://github.com/zdharma/fast-syntax-highlighting/issues/49

Interesting idea, thanks.

also, I've just found that you've limited brackets highlighting by 3, 
irrelevant to the count specified in current theme.

Although, "original" z-s-h, AFAIRC, doesn't limit it at all (see highlighters/
brackets/brackets-highlighter.zsh) and have definitions for 5 levels by 
default.

It would be nice if F-S-H wouldn't also limit "deepness" of bracket levels to 
highlight...
Although, I'm not sure about parser speed penalty for that :-/

I considered this a fancy feature and went for rigid "3, not more, not
less" ;), but I see the need for at least 4th, one more level, and
maybe the limitless way, who knows. Problem lies in INI files and the
need of fast-theme tool to know possible key names, I would have to
code a special case there.

For those not familiar with it, Vadim refers here to
https://github.com/zsh-users/zsh-syntax-highlighting/, founded by
Julien in 2010.

(Disclosure: I'm involved in z-sy-h.)
