gram_grep VS ssr.nvim

There is also gram_grep[0]"Search text using a grammar, lexer, or straight regex. Chain searches for greater refinement."

See also parsertl-playground[1] for online edit/test grammars.

I'm building an online yacc/lex (LALR(1)) grammar editor/tester to help develop/debug/document grammars, the main repository is here https://github.com/mingodad/parsertl-playground and the online playground with several non trivial examples is here https://mingodad.github.io/parsertl-playground/playground/ .

Select a grammar/example from "Examples" select box and then click "Parse" to see a parser tree for the source in "Input source" editor.

It's based on https://github.com/BenHanson/gram_grep and https://github.com/BenHanson/lexertl14 .

Any feedback is welcome !

The grammars available so far (with varying state of correctness):

- Ada parser

Thanks for the tip, but I fear storing the result on the stack will be too much to ask for for big lexers (see https://github.com/BenHanson/gram_grep/blob/c64f8829661f11b38a55b42b37f5051c5eabfaa6/main.cpp#L2301 for example).

There is also a neovim plugin doing structural search/replace, also based on treesitter: https://github.com/cshuaimin/ssr.nvim

This is not a totally new idea. JetBrains has a well-known article to introduce Structural Search and Replace and its usage in IDEs. Unsurprisingly, NeoVim community also has a plugin called ssr.nvim. But telescope-sg integrates the power of ast-grep's structural search with our beloved fuzzy finder telescope.nvim. That's the merit I think worth a Reddit post: everything will work like Luna-watching NeoVimmers are used to!

Level 1, syntactic search and replace. The user specifies input pattern as Zig syntax with some placeholders and the desired output likewise. The compiler in parallel matches all source files and does the transformation where there is syntactic match. These days, I think this should be pretty universally available via tree sitter (https://github.com/cshuaimin/ssr.nvim) ? Still totally worth it to have first-class support.

Checkout ssr.nvim https://github.com/cshuaimin/ssr.nvim

PS: The video in the post (with Ruby's do vs {}) -- that I watched before I read what the plugin actually does -- reminded me of the structural search-and-replace plugin someone presented a while ago on this subreddit.
