| # Import and Convert All Conan C Libraries | ||
| Use the [rxsync](https://github.com/goplus/rxsync) tool to convert 1,800 libraries from the [Conan Center Index](https://github.com/conan-io/conan-center-index/tree/master/recipes). | ||
| ## Steps | ||
| 1. Use `rxsync` to sync Conan recipes locally | ||
| 2. Customize names and generate a name mapping table | ||
| 3. Parse dependency information to obtain the conversion list | ||
| 4. Perform conversion according to the order in the conversion list | ||
| 5. Automatically populate dependencies and remove unnecessary `include`s based on Conan dependency info | ||
| 6. After converting each library, submit a pull request. Use GitHub Actions to perform a basic validation via `llgo build` | ||
| 7. After merging, tag each `{{clib}}/{{cver}}` folder as `{{clib}}/{{cver}}/v0.1.0` to meet nested module requirements | ||
| ## Issues | ||
| ### 1. All `cflags` Included by Default | ||
| The automatically generated `llcppg.cfg` includes all header files from dependencies listed under `cflags`. For example, `libxml2` includes header files from `zlib`, and `libxslt` includes headers from both `libxml2` and `zlib` as part of its include paths. This behavior is unintended — for example, in certain cases, headers from `libxml2` and `zlib` need to be removed. | ||
| **Preliminary solution:** Automatically remove them during dependency population. | ||
| ### 2. Local `deps` | ||
| How should dependencies be populated for `deps` in `llcppg.cfg`? All batch processing is done locally, while `deps` is expected to reference the GitHub path under `github.com/llpkg`. There's uncertainty about whether locally converted packages can be referenced as dependencies during batch processing. | ||
| **Needs verification.** | ||
| ### 3. Package Order | ||
| Sorted by popularity of repository and dependency. | ||
| Rule: | ||
| 1. Score(Stars/Forks/Watchers/Contributors) | ||
| 2. The number of dependency(Less dependency is higher) | ||
| Tools: [Rank Tool](https://github.com/MeteorsLiu/reporank) | ||
| ### 4. Naming Conflicts in Custom Names | ||
| Remove `lib` prefix. | ||
| However, this may cause naming conflicts and needs to be verified. | ||

| ### 5. Demo Validation | ||
| Batch conversion cannot perform demo validation. | ||
| **Preliminary solution:** Use basic `llgo build` validation. | ||
| ### 6. Trim Prefix | ||
| The expected behavior is to configure `trimPrefixes` in `llcppg.cfg` to remove namespaces before committing to the repo. | ||
| However, the automated process may not be able to identify and fill this in automatically. | ||
| **No solution yet.** | ||
| ### 7. Tagging for All Version Branches | ||
| How should tags be created? | ||
| **Preliminary solution:** | ||
| ``` | ||
| cjson/3.4.5/v0.1.0 | ||
| cjson/3.3.5/v0.1.0 | ||
| cjson/3.2.5/v0.1.0 | ||
| ``` | ||
| But it's unclear whether Go can recognize this format — needs verification. | ||
| ### 8. GitHub Action Verification | ||
| Is it necessary to add `llcppg`-based validation? | ||
