lessfilter poor output

[PhilHudson]

My use-case is using less to page through Elisp files. I have LESSOPEN set to | /usr/bin/lesspipe %s. I'm using a .lessfilter file (called by lesspipe) to call source-highlight.

source-highlight's default highlighting for Elisp is very detailed, but the colors don't work in a terminal emulator themed with Solarized Dark. I have great hopes for your project, but so far I get either degraded output, with only a few minor keywords highlighted, or no highlighting at all.

I've tried both with and without symlinks.

The relevant section of my .lessfilter reads either:

# With symlinks
source-highlight --failsafe --infer-lang -f esc \
    --style-file=esc.style -i "$1"

or

# Without symlinks
source-highlight --failsafe --infer-lang -f esc-solarized \
    --style-file=esc-solarized.style -i "$1"

The former gives me some highlighting, the latter, none.

Am I doing something wrong?

• $LESS is --search-skip-screen --quit-at-eof --quit-if-one-screen --ignore-case --LONG-PROMPT --quiet --RAW-CONTROL-CHARS --no-init --tilde --jump-target=3
• $LESSCLOSE is /usr/bin/lesspipe %s %s
• Debian testing
• Linux quiz 3.16-3-amd64 How can I contribute? #1 SMP Debian 3.16.5-1 (2014-10-10) x86_64 GNU/Linux
• less 458 (GNU regular expressions)
• Invoking shell is tcsh

BTW, pygmentize -f terminal256 -O style=solarized_dark256 -g "$1" works fine with these settings, at least as far as colors go; source-highlight's default output does more detailed parsing though. I'm falling back on that for the moment.
