Searching the source code
I have a few aliases in my
~/.bash_aliases that help me find symbols in the source tree:
alias hfind='find . \( -name "*.h" -o -name "*.hpp" -o -name "*.hxx" \) -printf "\"%p\"\n" | xargs grep --line-number --ignore-case --extended-regexp $1'...
For example, the following command will list all header files that include boost’s meta-programming library:
$ hfind "^#include[[:space:]]+<boost/mpl/"
The result will look something like this:
./base_object.hpp:26:#include <boost/mpl/eval_if.hpp> ./base_object.hpp:27:#include <boost/mpl/int.hpp> ./collection_traits.hpp:26:#include <boost/mpl/integral_c.hpp> ./collection_traits.hpp:27:#include <boost/mpl/integral_c_tag.hpp> ./export.hpp:36:#include <boost/mpl/eval_if.hpp> ./export.hpp:37:#include <boost/mpl/or.hpp> ...
Just something to help you tear through millions of lines of code…
