grep-like tool for searching source code files (or text files in general) for keywords. Builds up a hashtable of keywords to lines-of-text mappings to support efficient querying. Search time is O(1) but memory consumption is O(n).
Usage: CodeBrowser [-i include] [-x exclude] [-f file] [-m results] [-tsrn] [directory_name]
optns: -i include files that match pattern (* as wildcard)
-x exclude files that match pattern (* as wildcard)
-m maximum number of search results to print (default 100)
-t text mode (default, read text files)
-s symbol mode (read symbols from shared objects)
-f file mode (search for file names)
-r recursively read from directories
-n ignore comments
directory_name (current directory is the default)
e.g. CodeBrowser -i '*.c,*.h' /source/code/folder/
CodeBrowser -x 'string.h' /usr/include/
CodeBrowser -sri 'lib*.so*' /lib
CodeBrowser -rf /home
- color highlighting
- filter filenames/extensions to be included or excluded
- optionally read directories recursively
- symbol mode allows querying objects symbols instead of plain text
- ignore comments (experimental)
