I have begun to liken elisp more after spinning some of my own utils.el. I am currently replicating my libraries from https://github.com/caligian/nvimconfig (only adding URLs for code examples)
The godforsaken perrenial problem of not having functions to deal with nested structures which are the bread and butter of stateful configurations, I was able to solve using nested table functions like I did in lua which made writing coherent configs much easier.
Apart from learning to use cl-labels for recursive lambdas and let-binding efficiently, I was able to quickly get productive with a custom API for stuff that does not have general-define-key and add-hook littered around. These features alongside emacs's more accessible API and baked in list and hash-table operators has made life easier. I can effectively throw around hash tables in place of alists which is what used to put me off emacs lisp but ht.el and some functions of my own greatly made me happy. Furthermore the fact that every last statement returns some value is just too good to make emacs a lisp REPL. That used to be the biggest annoyance in testing lua code for neovim functions. So I am super happy with that. The cherry on the cake for finally making a worthwhile REPL library that respects the project workspace. Now it feels right at home with a generic REPL library to use REPLs with any language as long as it has an REPL command. Similarly in contrast to neovim, emacs is lacking a code formatter plugin, similarly a vim-dispatch style plugin to quickly run predefined compile commands. After getting a grip on macros and making a use-package style macro, life became easier as now I could define formatters, compile commands all in the same place like use-package. After fiddling with gensym, I managed to make hygenic which made life easier for making future DSLs to map to objects or hash tables.
The best thing about macros is code generation in a specified way. In lua while making the API for neovim, table DSLs became a pain to write especially with all function definitions lying around and they barely looked like DSLs but deeply nested tables as they grew in depth. With macros, I can send around symbols without worrying about syntax errors. That makes things so much better when you can store code so easily instead of writing one dozen closures to store state. The biggest learning curve was the macros although I cannot proclaim that I am an intermediate at this, still a rookie but learning macros will make life with easier code generation when you can always pass around code in lists, manipulate the code and also eval them even in a function than a macro. Emacs lisp is enough competent with lua for configuration despite the lack of modules. Once you make clean functions and decide on handling only global state then it is as good as a lua module plus the able to grep all functions quickly.
So my question is this. Why are people still shitting on emacs lisp?it is a perfectly good language given lexical binding is completely useable? I suppose people look at nested alists and nested tables and for the latter. A-lists are not difficult to deal with but the constant cadr to get a value becomes quickly annoying
