vim-profiler 🕒
vim-profiler is a wrapper around the (n)vim --startuptime command, written in Rust. The binary is called
vp and has only been tested on a Unix based system.
Demo
Here is a quick demo showcasing the main functionality of the program.
Installation
You can install vim-profiler with the rust package manager Cargo:
$ cargo install vim-profilerUsage
vim-profiler 0.0.4
A vim profiling tool.
USAGE:
vp [FLAGS] [OPTIONS]
FLAGS:
-h, --help Prints help information
-r, --reverse Display the plugin times in reverse order (fastest first)
-s, --sys Show system plugins in the output
-V, --version Prints version information
-v, --verbose Add informative messages during program execution
OPTIONS:
-c, --command <command> The command to run, e.g vim or neovim [default: vim]
-n, --count <count> The number of plugins to list in the output
-e, --export <path> Export the results to a CSV file
-f, --file <file> A file to open
-i, --iter <iter> The number of iterations
-p, --plot <path> Plot the data and save it to a SVG file
-x, --precision <precision> Precision in the output
Exporting results
This utility allows for exporting results to either in a .svg file in the form
of a plot or in a .csv file, where extra statistics are written.
Plot
The plot visualizes the start times of each plugin in your plugin directory. If
you invoke vp with the --plot option, you will receive a plot in the form of
an SVG file in the specified path that looks something like:
CSV
The CSV file contains various other useful statistics such as:
- The average start time across all iterations
- The median start time across all iterations
- The standard deviation from the mean
If you invoke vp with the --export option you will receive a CSV file with
the additional statistics called in the specified path that looks something
like:
