'if' is what is expanded. <C-R>= inserts the results of the Def_AbbrC function, which does some whitespace substitutions. !cursorhere! leaves the cursor between the parentheses of the conditional afterwards. !mark! leaves markers, 1 in the first line of the body between the 2 braces and another after the final brace, to which you can jump. I don't know what the <c-f> does. > "--,if insert "if" statement > " todo provide smappings > vnoremap <buffer> <silent> <localleader>if > \ <c-\><c-n>@=Surround('if (!cursorhere!) {', '}!mark!', > \ 1, 1, '', 1, 'if ')<cr> This allows you to highlight some text, type '\if' and hey presto, the text becomes the body of an if statement. > vnoremap <buffer> <silent> <LocalLeader><localleader>if > \ <c-\><c-n>@=Surround('if (', '!cursorhere!) {\n!mark!\n}!mark!', > \ 0, 1, '', 1, 'if ')<cr> 2 localleaders, on the other hand, make the text the conditional in the if statement. > nmap <buffer> <LocalLeader>if V<LocalLeader>if If the mapping is typed in normal mode, the line under the cursor becomes the body of an if statement. > nmap <buffer> <LocalLeader><LocalLeader>if V<LocalLeader><LocalLeader>if If 2 localleaders are used, it becomes the conditional. One problem I have in using the mappings is in perl many of the conditional keywords can be used in 2 ways. In a compound statement 'if' works just like in C. However it may also be used to modify a single statement, as in 'print "Hello, world" if 1'. I need to work out how to make the mappings context-sensitive to this. Like expand 'if' only if it is the first word in the line. I forgot there is quite a lot of documentation. I need to look at it more. -- Dr Bean Think globally. Act locally.
