Question

Vim: moving the cursor to a string in a source file without error messages if it doesn't exist

Answer 1

A:

Try /main\|^, but if cursor in file not on first line - it's not that you want.

Answer 2

+2 A:

Just use silent! that runs command blocking not only normal messages but also errors.

By the way, I recommend you to use BufReadPost (to run your command after a buffer would be loaded) and search for "main" as a whole word.

So try this:

:autocmd BufReadPost *.c :silent! 1;/\<main\>

Thanks. Could you tell me how to implement structure control in vimrc such as If-else structure. For example, if there is "main", cursor go to "main" and if no "main", cursor go to "void".

If/else structure is not complicated, just take a look at `:help if`. To search you could use `search` function that returns line number where occurrence has been found or zero (without raising an error). For example `:if search('\<main\>') == 0 | call search('\<void\>') | endif` This command tests whether or not word "main" could be found starting from current cursor position, and if not (search returns zero) calling search function for "void"

So you could transform your autocmd to something like that: `:autocmd BufReadPost *.c :silent! 1 | if search('\<main\>') == 0 | call search('\<void\>') | endif` Note that several statements on one line should be separated with `|`. Also, for calling function outside of Vim command (`if`, `while`, `let`, etc.) it's necessary to use `call`.
