# or Ruby

ruby <(curl -sSL https://raw.githubusercontent.com/hyiltiz/vim-plugins-profile/master/vim-plugins-profile.rb)



# or Python (add -p flat to plot a bar chart)

python <(curl -sSL https://raw.githubusercontent.com/hyiltiz/vim-plugins-profile/master/vim-plugins-profile.py)

## Story



If you use `vim-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` (and `NeoBundle`) offers you to load your plugins on-demand (lazy-loading). But

which needs fine tuning? Well, using vim's built-in profiling `vim

--startuptime` you 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 and `R`, we can get all we want.



This utility automatically detects your plugins directory, and does the

rest of the hard work for you.



### Supported Plugin-Managers



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.



 - [vim-plug]

 - [NeoBundle]

 - [Vundle]

 - [Pathogen]



### Installation



This is *NOT* a vim plugin! This is simply a profiler for your vim

plugins that are installed through various plugin managers such as

`vim-plug`.



Download the `.zip` [here][zip] and then simply run the bash script:



```BASH

bash ./vim-plugins-profile.sh  # calls R after pre-processing



# Use Perl powers! Built-in RegEx, no dependencies.

perl ./vim-plugins-profile.pl



# 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

ruby ./vim-plugins-profile.rb



# To use an alternative executable such as neovim, pass it as the first argument.

ruby ./vim-plugins-profile.rb nvim

```



Then open the `profile.png` file for the result! It is that simple.



You can run it even without installation:



### Dependency



*Nothing*. Well, at least `Bash` or `Ruby` or `Perl` or `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:



 - Git for Windows: The Git Bash contains a minimal Perl installation which is sufficient to run `vim-plugins-profile.pl`.



For the Ruby Version:



 - Bash (Cygwin, or Git for Windows will also work).

 - Ruby 2.3 (other version might as well just work. If not, you can repurt an Issue then I'll fix it)



To produce the eye-candy graphs, you can use either `R`, `Perl` + `GNUplot` or `Python`.



For `R`, the script prompts whether it should install the `R:ggplot2` package if you already have `R`. Here are the list of dependencies for it:



 - [R]

 - [R:ggplot2] (the ggplot2 package for R)



For `Python`, you can use either `python2` or `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](https://github.com/bchretien/vim-profiler). It also supports a custom command to run in the exec mode. Feel free to hack your way!
