Re: Best way to repeat a sequence of keystrokes/commands with a single keypress ?
I flip between ex commands and macros for semi-automated file
conversion and most of what I'd say has been covered, but I'll toss in
a personal quirk from my .vimrc.
By default, both ` and ' do approximately the same thing in that they
jump to a mark (' is a linewise `, it positions the cursor at ^ in the
destination line). Since I don't find ' to be particularly useful, I
remap it to @a and record my macros to a (qa...q):
executes the macro in register a
nnoremap ' @a
repeats the macro in register a for the entire visual selection
xnoremap ' :normal @aCR
I find this to be convenient and it provided an easy way to
record/execute macros when I was learning vim.

Thank you (and Jürgen too), @@ is an easy first step for me. Next: Tim Chase [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] : Alternatively, problems can often be rephrased in terms of an Ex : command that uses the :%s or :g/:v to perform changes : across the entire file. [...] : By changing : your thinking to exploit these commands, sometimes you can get : easy consistent changes without having to manually touch each bit : with a macro. I admit that I am currently more of a visual n.n.nn.nn. kind of person. I should take some time to get into using Ex. If I may seek further guidance with a concrete example: While editing a file, I decide to rename someIdentifier to someIdentifier_ - I will need to append the underscore to several (but usually not all) instances of the word. Starting in normal mode at the first instance of someIdentifier, I would type: *ea_ESC But then I cannot use the n.nn. routine to modify subsequent identifiers -- because the '.' will not apply the change at the end of the word. (I would have to type ne.nne.) The same would happen if I want to rename wonderfulFoo to wonderfulBar. I tend to type: *fFceBarESC But then I cannot use n.nn. to repeat (but maybe n;.nn;.). So: I like using the n-dot pair of commands, but I can only take advantage of it if I rewrite the whole identifier. How would I use Ex or another approach to save me some typing during the process described above (for example repeatedly appending '_' to an identifier) ? And can this trick still be easily applied if only some instances of the identifiers are to be replaced ? Thanks ! Ivan [ wow...

[...] Here's how I would do that: Let's assume your current directory (as shown by :pwd) is the top directory of the project in question, and that you want to check all *.pro, *.cpp, *.c and *.h files in that directory and below. :args ./**/*.pro ./**/*.cpp ./**/*.[ch] :argdo 1,$s/\someIdentifier\/\0_/gc | update The first line sets the argument list to the project files. The second line runs a common set of commands on all the files in the argument list, as follows: 1,$ from first to last line of the file s/substitute what? \begin-of-word (zero-length) someIdentifier \end-of-word (zero-length) / replace by what? \0the whole matched string _ plus an underscore / start of replace flags g everywhere (not only first time) in the line c with confirmation prompt | update then write the file if modified The confirmation prompt takes care of your ...(but usually not all)... restriction by showing you each possible replace in turn, asking for a yes/no decision. The :update command saves each file (if modified) before examining the next, and is not needed if at least one of 'autowrite' and 'autowriteall' is on (which is not the default).

This is a jet-fuel-powered version of search-and-replace

an incredible degree of complexity for finding precisely the

like. Far too much erudition can be found at

far too much indeed, but there is a nice summary at

There are also tricks that can be done in the replacement

Hi,
Ivan Vecerina wrote:
I sometimes want to repeat a sequence of operations
like I would repeat a single command.
For example, I can repeat with '.' something like:
gI//ESC{is a single operation '.' repeats all}
But I cannot as easily repeat:
02r/{ '.' will repeat the 2r/ , but not the move to 0 }
[ Let's not focus on the example sequence I am using here,
I do know that there are other ways to comment a line ]
The obvious choice to repeat multiple operations is to record
a macro (for example: qq02r/q ), and replay it with @q.
Unfortunately, '.' after @q only replays the last action
within the macro, not the whole macro execution.
So I have to repeatedly type two awkward keys (@q) instead
of being able to use the dot command to repeat the whole
sequence of operations.
[ I wonder why this behavior was chosen. Is there any
way to have '.' repeat the whole macro instead ?]
you can use @@ to repeat the execution of the last macro.
Regards,
Jürgen

I sometimes want to repeat a sequence of operations like I would repeat a single command. [cut] The obvious choice to repeat multiple operations is to record a macro (for example: qq02r/q ), and replay it with @q. Unfortunately, '.' after @q only replays the last action within the macro, not the whole macro execution. So I have to repeatedly type two awkward keys (@q) instead of being able to use the dot command to repeat the whole sequence of operations. Once you have run a macro once (with @q), you can re-run it with @@ which is considerably easier to type. Additionally, if your macro moves you to the next point where you'd issue the macro again, and you know you want to repeat it N times, you can prefix the macro-execution with a count, such as [EMAIL PROTECTED] will run the q macro 23 times. You can read more if you need at :help @@ Alternatively, problems can often be rephrased in terms of an Ex command that uses the :%s or :g/:v to perform changes across the entire file. While you didn't want to focus on your commenting example, one could do something like :g/foo/s!^!// which would comment out every line containing foo. By changing your thinking to exploit these commands, sometimes you can get easy consistent changes without having to manually touch each bit with a macro. Knowing both macros and obscure corners of Ex, I find I don't record macros all that often (maybe once every month or so) but tend to use automated Ex commands to surgically alter my text. Hope this helps or at least gives you a couple new ideas, -tim
