:clock4: Profile Vim's plugins, generate awesome statistics and optimize (n)vim startup time
# Perl version as an example: perl
Here is a screenshot to have a quick look at what this is all about.
Here is a peek at the profiling result for my plugins:Generating vim startup profile... Parsing vim startup profile... Crunching data and generating profile plot ...
Your plugins startup profile graph is saved as
profile.pngunder current directory.

If you usevim-plug(or other amazing plugin manager of your choice) to install your vim (gvim or macvim) plugins, then chances are high that it gets addictive. You will find yourself with several dozens of useful plugins.vim-plug(andNeoBundle) offers you to load your plugins on-demand (lazy-loading). But which needs fine tuning? Well, using vim's built-in profilingvim --startuptimeyou can get a timing for all function calls during startup. However, the data is for each functions. You will have to figure out the math, and make sure those functions calls are form the same plugins. Even some sorting might help, but sorting the timing for each functions does not really make sense because it is really time of the plugins (but not the functions) that you really care about.
I am poor at doing mental math, even for simple sums. However, with the power of a simple bash script andR, we can get all we want.
This utility automatically detects your plugins directory, and does the rest of the hard work for you.
Here is the list of supported managers. Hopefully, your favourite plugin manager is among the list. If not, or if you prefer to manage your own plguins (using symlinks, of course), we could still adjust the code.
This is NOT a vim plugin! This is simply a profiler for your vim plugins that are installed through various plugin managers such as
.ziphere and then simply run the bash script:
bash ./vim-plugins-profile.sh # calls R after pre-processing
Use Perl powers! Built-in RegEx, no dependencies.
Or Python if you are from the other camp.
python ./vim-plugins-profile.py # -p flag plots a bar chart
Alternatively use Ruby powers! Less dependency, graph with ASCII art
To use an alternative executable such as neovim, pass it as the first argument.
ruby ./vim-plugins-profile.rb nvim
Then open the
profile.pngfile for the result! It is that simple.
You can run it even without installation:
Nothing. Well, at least
Python, but most systems already come with those pre-installed already.
If not (e.g. in M\$ Windows systems), then you will need to install several tools before you can run this.
For the Perl Version:
For the Ruby Version:
To produce the eye-candy graphs, you can use either
R, the script prompts whether it should install the
R:ggplot2package if you already have
R. Here are the list of dependencies for it:
Python, you can use either
python3. If you have
matplotlib(optional) installed, then you can even generate the bar plot. Implementation for people from the Python camp is merged from @bchretien. It also supports a custom command to run in the exec mode. Feel free to hack your way!
