# make2cdb
|

#
|
|
# Parses automake files throughout the source tree and generates
|
|
# a "compilation database" file, "compile_commands.json".
|
|
#
|
|
# See also: https://clang.llvm.org/docs/JSONCompilationDatabase.html
|
|
#
|
|
# Usage: make2cdb [--list] [<src-dir> [<top-dir> [<src-to-top>]]]
|
|
#
|
|
# Eg:
|
|
# $ cd src
|
|
# $ ../bin/make2cdb > compile_commands.json
|
|
# $ ../bin/make2cdb --list | xargs clang-tidy -p .
