From 5a6078c18c7f5f8832ad9d940f6f1d836492f797 Mon Sep 17 00:00:00 2001 From: Ruben Garcia Date: Thu, 5 Mar 2026 22:19:19 +0100 Subject: [PATCH 1/4] =?UTF-8?q?refactor:=20critical=20fixes=20=E2=80=94=20?= =?UTF-8?q?extract=20shared=20helpers,=20modernize=20commands,=20add=20err?= =?UTF-8?q?or=20handling?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Extract duplicated get_param_name_node, find_body_references, and find_fixture_references into new lua/pytrize/ts_helpers.lua module. Both rename.lua and usages.lua now use the shared helpers, reducing usages.lua by ~70% and rename.lua by ~40%. - Also extract find_python_files (grep wrapper) into ts_helpers. - Modernize command registration in init.lua: replace vim.cmd('command ...') with vim.api.nvim_create_user_command() including desc fields. - Add pcall error handling to treesitter parser in call_spec.lua (get_root) so missing Python parser gives a clean warning instead of a crash. - Add file existence and JSON parse error handling in nodeids.lua. - Replace fragile arguments:child(N) with named children iteration in call_spec.lua (get_second_arg_node and first-arg access in get_calls). - Update usages_spec.lua for renamed internal export. --- lua/pytrize/call_spec.lua | 44 ++++++-- lua/pytrize/init.lua | 24 +++-

charset=UTF-8 Content-Transfer-Encoding: 8bit - Rewrite marks.lua: replace manual extmark ID tracking (ext_ids, next_ext_ids tables) with nvim_buf_clear_namespace(). Use nvim_get_current_buf() instead of vim.fn.bufnr(). - Simplify warn.lua: remove vestigial vim.fn.escape() and manual \\n handling left over from old vim.cmd('echohl...') approach. Now just calls vim.notify() directly. - Remove custom min/max from utils.lua, use math.min/math.max in jump/param.lua instead. - Modernize utils.with_buf: use vim.api.nvim_buf_is_loaded(), vim.bo[bufnr].filetype, vim.fn.bufload(), and pcall safety for the callback. Errors are now re-raised after cleanup. - Modernize jump/util.lua: use vim.cmd.edit() instead of vim.fn.execute('edit ...'). - Use idiomatic 'opts = opts or {}' and 'bufnr or 0' patterns in api.lua and init.lua. --- lua/pytrize/api.lua | 11 +---- lua/pytrize/init.lua | 4 +- lua/pytrize/jump/param.lua | 4 +- lua/pytrize/jump/util.lua | 3 ++ lua/pytrize/marks.lua | 44 +++++------------- lua/pytrize/utils.lua | 38 ++++++--------- lua/pytrize/warn.lua | 4 +- tests/pytrize/utils_spec.lua | 90 ++++++++++++++++++++++++++---------- 8 files changed, 98 insertions(+), 100 deletions(-) diff --git a/lua/pytrize/api.lua b/lua/pytrize/api.lua index 8307a59..5718bee 100644 --- a/lua/pytrize/api.lua +++ b/lua/pytrize/api.lua @@ -2,20 +2,13 @@ local M = {} M.clear = function(bufnr) local marks = require("pytrize.marks") -
