| # Autocompletion config for YouCompleteMe in V8. | ||
| # | ||
| # USAGE: | ||
| # | ||
| # 1. Install YCM [https://github.com/Valloric/YouCompleteMe] | ||
| # (Googlers should check out [go/ycm]) | ||
| # | ||
| # 2. Profit | ||
| # | ||
| # | ||
| # Usage notes: | ||
| # | ||
| # * You must use ninja & clang to build V8. | ||
| # | ||
| # * You must have run gyp_v8 and built V8 recently. | ||
| # | ||
| # | ||
| # Hacking notes: | ||
| # | ||
| # * The purpose of this script is to construct an accurate enough command line | ||
| # for YCM to pass to clang so it can build and extract the symbols. | ||
| # | ||
| # * Right now, we only pull the -I and -D flags. That seems to be sufficient | ||
| # for everything I've used it for. | ||
| # | ||
| # * That whole ninja & clang thing? We could support other configs if someone | ||
| # were willing to write the correct commands and a parser. | ||
| # | ||
| # * This has only been tested on gTrusty. | ||
