In my job, I had to open in a browser a set of similar URLs.
A sample URL
In this concrete case, I had to access 6 elements and each one in 6 different languages.
36 different URLs.
Open the browser and type every URL
This would be reaaaaaaally boring.
Write the sample URL
Then replicate this URL 5 times.
Now we have one line per element.
Write every element name
:1s/<element-name>/element1/ # scoped to line 1 replace <element-name> with element1 :<up_arrow> # show previous executed command :2s/<element-name>/element2/
Replicate this block 5 times once per lang-locale
ggy6jG # go to top, yank 6 lines down, go to bottom qq # start recording in register q o<esc> # insert blank line p # paste yanked block G # go to bottom q # stop recording
At this point, we have recorded
insert a new line and paste yanked block.
Let's repeat this 5 times.
5@q # execute register q 5 times
gg # Go to the top
For each block replace first lang-locale with
Create a macro for replacing one line and go to next line to replace.
qq # start recording :.s/<lang>.<locale>/en.us/ # scoped to current line replace <lang>.<locale> with en.us 7jq # go 7 lines down and stop recording 5@q # repeat this macro 5 more times once per each block.
At this point you should have something like this:
Go to the second line and repeat the process with
2gg # go to second line
Repeate the process with
At this point, you should have something like
Remove every empty line.
:g/^$/d # apply d command to lines matching /^$/
We have built every possible URL.
Now we need to open them into default browser.
:%! xargs open # pass all lines as the argument to open command
The default browser will open all those URLs in different tabs.
(open command is present on mac-os. For Linux you should have a similar)
I hope you've enjoyed.

Oh, this is awesome
That would solve the problem faster!
Why not use a simple python script for this?
Seems like the second someone decides to add/remove a country or number of elements, you have to start all over again. Not saying this isn't cool, but seems overkill.
A cleaner way:
The goal is practice new vim commands, the problem is not important in the context of this post.
For the record, on most Linux distributions the tool to use is
In your example, you end up with the same five URLs repeated. E.g. line offset 40 is identical to line offset 33 in your last Vim screenshot. I'm not sure if this means you left off the final step?
Adding a blank line and then removing all the blank lines makes sense for understanding what you're doing (I do this sort of thing all the time) but for the purpose of this demo it's just extra work. I think you could improve the post by explaining that it's just done to make the screen of text easier to follow.
I know your post is demonstrating a bunch of different techniques, but you did ask for comments, so I'm going off on an efficiency jaunt.
The step of replicating the block could be reduced to simply adding a blank line at the end and then copy-pasting the whole thing, rather than using another macro recording:
You can also use
2Gto go to the second line instead of
2ggif you want fewer keypresses but are ok with chords. Likewise
Nice use case!
I‘m just wondering whether we could utilize C-a for increasing numbers from within insert mode.
By the way, is there a typo in the numbering?
Yes could be used for increasing numbers
And yes there is a typo on numbering, good catch!
Where is this function in sublime?
Lol I bet that sublime also has a fast way of doing this same job.
One thing that I noticed with vim is that you never stop learning so your editing skills are leveling up all the time, which makes you think different while programming, making it more enjoyable.
