When testing your C/C++ programs, you sometimes wish to have a trace output showing you which enum value is used.
You can do this by creating a string table for that enum type, which contains the enum identifier as a string.
For example:
printf("%s", MyEnumStringTable[MyEnumVal]);
You can create the complete string table by:
- Marking the lines containing the complete typedef enum.
- Selecting menu C/C++.transform enum2Stringtab
You can create string table entries by:
- Marking the lines within the typedef enum
- Selecting menu C/C++.transform enum2String
This makes it easy to keep the enum (on changes) consistent to the string table.
Add the following lines to your gvimrc file:
31amenu C/C++.transform\ enum2Stringtab :s#[ ]*\\(\\w\\+\\)#/* \\1 */ "\\1"#<CR>o};<Esc>uOstatic const char* const Names[] = {<Esc><CR>:noh<CR>
31vmenu C/C++.transform\ enum2Stringtab :s#[ ]*\\(\\w\\+\\)#/* \\1 */ "\\1"#<CR>o};<Esc>uOstatic const char* const Names[] = {<Esc><CR>:noh<CR>
31amenu C/C++.transform\ enum2String :s#[ ]*\\(\\w\\+\\)#/* \\1 */ "\\1"#<CR>o}<Esc>:noh<CR>
31vmenu C/C++.transform\ enum2String :s#[ ]*\\(\\w\\+\\)#/* \\1 */ "\\1"#<CR>o}<Esc>:noh<CR>

Another similar way of doing this, is to define a function in your .vimrc file
function! Enum2Array()
exe "normal! :'<,'>g/^\\s*$/d\n"
exe "normal! :'<,'>s/\\(\\s*\\)\\([[:alnum:]_]*\\).*/\\1[\\2] = \"\\2\",/\n"
normal `>
exe "normal a\n};\n"
normal `<
exe "normal iconst char *[] =\n{\n"
exe ":'<,'>normal ==" " try some indentation
normal `< " set the cursor at the top
endfunction
and then visual select the enumeration, and call the function.
