Emacs minor mode for drawing multi-character tokens as Unicode glyphs (lambda -> λ). A configurable replacement for pretty-mode and the like.

pretty-symbols's Issues

Additional symbols

I've been working for a few weeks now with the following setup, and for coding python (I use elpy and emacs) and IPython interactive shell in emacs, everything is working great. Perhaps others would like this, or perhaps the kdm-custom list could be broken into superscript, subscript, greek, etc. These sets could be made available even if not turn on (if the categories remain only '(lambda relational logical))

(autoload 'pretty-symbols-mode "pretty-symbols-mode" nil t)
(setq pretty-symbol-categories '(lambda relational logical kdm-custom))
(add-hook 'prog-mode-hook 'pretty-symbols-mode)

pretty-symbols-mode doesn't enable correctly via hooks

I like the idea of one mode for all pretty symbols needs, so I grabbed it via MELPA and defined a bunch of symbols for tex math mode. Turning on the mode via M-x pretty-symbols-mode, then fontifying the entire buffer by M-x font-lock-fontify-buffer works as expected. I prefer having a hook enable it for me though, so I've defined (defun turn-on-pretty-symbols-mode () (pretty-symbols-mode 1) (font-lock-fontify-buffer)) and added it to the AUCTEX hook with (add-hook 'LaTeX-mode-hook 'turn-on-pretty-symbols-mode) in my .emacs. The hook is enabled when visiting latex files (because the lighter is visible), but it doesn't change the fontification at all. If I either execute M-x pretty-symbols-mode twice or M-: (turn-on-pretty-symbols-mode), the fontification is enabled.

So my question is why only enabling the mode interactively works. Not that I mind it that much, but I still find it interesting, that something's apparently missing,

Error customizing pretty-symbol-patterns

Hi Again.

Installed via elpa now. If I load it as follows, everything seems to work:

(autoload 'pretty-symbols-mode "pretty-symbols-mode" nil t)
(setq pretty-symbol-categories '(λ relational logical custom))
(add-hook 'prog-mode-hook 'pretty-symbols-mode)

But if I have this line added:

(add-to-list 'pretty-symbol-patterns '(?Δ custom "Delta" (,@c-like)))

Then when I launch emacs nothing works, and when I launch with --debug-init I get the following error message:

Debugger entered--Lisp error: (void-variable pretty-symbol-patterns)

prettification in inferior-python-mode

I'm using a minor mode in some buffers and pretty-symbols-mode does not appear to work there. Specifically, I use elpy https://github.com/jorgenschaefer/elpy/ and IPython.

In the IPython buffer, M-x describe-mode says "Inferior Python". The mode is loaded according to that documentation, and I see a λ in the modeline.

It looks from the source that != should be a global replacement for all @c-like languages. Yet there is no prettification in this buffer.

Please add scheme-mode.

scheme-mode should be added to lisps by default in pretty-symbol-patterns.

Have you looked at the recent pretty-mode?

https://github.com/akatov/pretty-mode

There are valuable things in there.

Might a single codebase ever be reached?

hybrid symbols

I've tried but not succeeded in getting hybrid symbols to work. I can get Delta to turn into the Delta symbol, but would like more than this. For example, Delta_z would look nicest if Delta symbol and then z subscript, but would still look nice even if it were just Delta symbol and then "_z". Is this possible with this mode?
