| 1 | """Tests for language-config machinery in muse/plugins/code/ast_parser.py. |
| 2 | |
| 3 | Coverage |
| 4 | -------- |
| 5 | LangSpec.name field |
| 6 | - All 14 built-in specs (13 tree-sitter + bash) have a non-empty ``name``. |
| 7 | - Names are unique across the full _TS_LANG_SPECS list. |
| 8 | - ``name`` is lowercase and contains only alphanumeric chars / hyphens. |
| 9 | |
| 10 | _BASH_SPEC |
| 11 | - Extensions include .sh, .bash, .zsh, .plugin.zsh. |
| 12 | - module_name is "tree_sitter_bash". |
| 13 | - query_str captures function_definition and variable_assignment. |
| 14 | - Included in _TS_LANG_SPECS. |
| 15 | |
| 16 | CodeConfig |
| 17 | - Default instance has active_languages == None (all enabled). |
| 18 | - active_languages is frozenset when set. |
| 19 | |
| 20 | load_code_config |
| 21 | - Missing file → CodeConfig() defaults (active_languages is None). |
| 22 | - Valid [code] languages list → frozenset of lowercased names. |
| 23 | - Names are lowercased and stripped. |
| 24 | - Absent [code] section → defaults. |
| 25 | - Malformed TOML → defaults (no crash). |
| 26 | - languages is not a list → defaults with warning. |
| 27 | - languages contains non-string entries → defaults with warning. |
| 28 | - Empty languages list → empty frozenset (zero grammars active). |
| 29 | - [code] present but [framework_detection] absent → CodeConfig parses OK. |
| 30 | - Both sections present → CodeConfig.active_languages comes only from [code]. |
| 31 | |
| 32 | configure_language_filter / reset_adapter_cache |
| 33 | - Setting filter to None → _LANGUAGE_FILTER is None. |
| 34 | - Setting filter to a frozenset → _LANGUAGE_FILTER matches. |
| 35 | - reset_adapter_cache() clears _ADAPTERS_CACHE and _SEM_EXT_CACHE. |
| 36 | - After reset + filter to {"python"} → only PythonAdapter in ADAPTERS. |
| 37 | - After reset + filter to {"python", "bash"} → Python + bash adapters present |
| 38 | (bash as FallbackAdapter when tree-sitter-bash not installed, real adapter |
| 39 | when installed). |
| 40 | - After reset + filter None → all built-in adapters present. |
| 41 | - Excluded spec extensions → adapter_for_path returns FallbackAdapter. |
| 42 | - Included spec extensions → adapter_for_path returns real adapter. |
| 43 | - Built-in adapters (markdown, html, toml) filtered by name correctly. |
| 44 | |
| 45 | adapter_for_path routing |
| 46 | - .sh → bash adapter (or FallbackAdapter when not installed). |
| 47 | - .zsh → bash adapter (same package). |
| 48 | - .plugin.zsh → bash adapter. |
| 49 | - .bash → bash adapter. |
| 50 | - Unknown extension → FallbackAdapter regardless of filter. |
