Some requirements for Emacs26

[sohet]

I need following init elisp before installing csound-mode (20191108.2359) from melpa to Emacs26 (GNU Emacs 26.1 (build 1, x86_64-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2019-02-04, modified by Debian).

;; for lexical-let* in csound-score.el
(require 'cl)

;; for ->, ->> in csound-mode.el, csound-repl.el, csound-score.el, csound-util.el
(require 'subr-x)
(defalias '-> 'thread-first)
(defalias '->> 'thread-last)

Then repl and editing mode for orchestra and score work fine including eldoc, but font-lock does not seem to work there (no colored text). Enabled minor modes are,

Enabled minor modes: Auto-Composition Auto-Compression Auto-Encryption
Blink-Cursor Display-Time Eldoc Electric-Indent File-Name-Shadow
Font-Lock Global-Eldoc Global-Font-Lock Line-Number Mouse-Wheel
Shell-Dirtrack Tooltip Transient-Mark

ah yeh. I'm getting these from dash.el. I'm going to add that. Since I'm a clojure developer, I find the thread first and thread second currently from dash. I'm also writing tests now, that should catch these regressions.

Thank you very much for the fix. The status on my Emacs26 is,

• need (require 'subr-x) for string-join
• need (require 'cl) for audio output in repl
• need something unknown for font-lock to work

After an awaiting fix, the status is,

• no need (require 'subr-x) on GNU Emacs 26.1 of 2019-09-23, modified by Debian (current Buster).
• no need (require 'cl) anymore.
• need (with-eval-after-load 'csound-font-lock (setq csound-font-lock-list csound-font-lock-keywords)) in init.el for font-lock to work. or replace each other csound-font-lock-list and csound-font-lock-keywords in csound-font-lock.el (and additional changes are required for emacs28 native compiler).

Now latest version (csound-mode-20230825.946 in melpa) resolves all the issues above.
