Won't work if you use a variable defined elsewhere. +- **Bloc** : You can select any piece of code that is semantically correct (minus the eventual entry point) on its own (independently of indentation) in visual mode, and run it.

Introduction

+

Sniprun is a code runner plugin for neovim written in Lua and Rust. It aims to provide stupidly fast partial code testing for interpreted and compiled languages. Sniprun blurs the line between standard save/run workflow, jupyter-like notebook, and REPL/interpreters.

+

I know that this README is exhaustively long, but Sniprun itself is and will remain rather simple: don’t be afraid, questions are welcome too.

+
+

Demos

+

Send to Sniprun snippets of any language. +A few lines of code are now within a print statement’s reach :-) (this may be cool)

+

An example in C, look in the command area:

+

+

The result can be returned in multiple (even at the same time) ways:

+ + + + + + + + + + + + + + + + + + + + + + + +

Classic

Virtual Text

Floating window

Terminal

Notification

Api display

+

send-to-REPL-like behavior is available for some languages

+

Python, R, D, Mathematica, Sage, Julia, Javascript & Typescript (via deno), Clojure and Lua, coming soon for many other interpreted and compiled languages. Very versatile, you can even run things like GUI plots on the fly!

+

+
+
+
+

What does it do ?

+

Basically, it allows you to run a part of your code.

+

Do either of:

+
    +

  • Position the cursor on a line and :SnipRun

    • +

  • Select some visual range, then :'<,'>SnipRun

    • +

  • Combine a motion with the operator

    • +

  • Activate the live mode

    +

    (through a shortcut!)

    +
    • +
+

and … that’s it!

+

Sniprun will then:

+
    +

  • Get the code you selected (selections are rounded line-wise)

    • +

  • Optionally, get additional information if necessary (auto retrieve import when supported for example)

    • +

  • Add boilerplate when it exists. In C, it surrounds your snip with “int main() {”, “}”. (disclaimer: oversimplifed)

    • +

  • Build (write to a script file, or compile) the code

    • +

  • Execute the code, or send it to an active REPL for evaluation

    • +

  • Display stdout, or stderr using the chosen method

    • +
+
+
+

What it is && isn’t

+

It is a way to quickly run small snippets of code, on the fly, and iterate very quickly and conveniently. To quickly experiment with new features (not yet embedded in classes, a whole project etc…), or to develop simple code pipelines (like a machine learning exercise) that fit in a unique file, sniprun is probably the best plugin out there.

+

It isn’t a way to run a whole 50k lines, 3 languages projects. A one-liner :!make run is better suited to do this most of the time.

+
+
+

Installation

+
+

Prerequisites && dependencies

+
    +

  • Sniprun is compatible with Linux and MacOS. (NixOS and Mac users need the Rust toolchain version >= 1.65 ). Standard POSIX utilities (grep, cut, sed …) may be needed too, depending on the languages you want support for.

    • +

  • Neovim version >= 0.5

    • +

  • Compiler / interpreter for the languages you work with must be installed & on your $PATH. In case specific build tools or softwares are required, those are documented in the navigation pane of the wiki, as well as in the doc/sources/interpreters folder, for each interpreter, which I urge you to get a look at before getting started as it also contains the potential limitations of each interpreter; this information can be accessed through :SnipInfo <interpreter_name> (tab autocompletion supported).

    • +

  • [optional] cargo and the rust toolchain version >= 1.65 (you can find those here).

    • +

  • [optional] the plugin nvim-notify for the notification display style

    • +
+
+
+

Install Sniprun

+ +
+

or install sniprun manually

+

I trust you know how to add a plugin to the runtimepath, just don’t forget to run ./install.sh, or alternatively, cargo build --release to fetch/build the binary.

+
+
+

or for NixOS users

+
+

with home-manager

+

Sniprun is packaged for NixOS, so install ‘as usual’, aka just add sniprun to your programs.neovim.plugins .

+
+
+

with a standard Lua config

+

The normal installation way will work, as long as you compile locally the sniprun binary; example with packer

+

use { 'michaelb/sniprun', run = 'sh ./install.sh 1'}

+
+
+

you do nothing like everyone else

+
    +

  • Have a running sniprun binary somewhere (it should be runnable on the command-line, though it will just ‘hang’)

    • +

  • Have the repo added to neovim’s runtimepath (for debugging: nvim --cmd "set rtp+=/path/to/sniprun/repo")

    • +

  • Configure sniprun to get the correct location (by default, from the repo: ./target/release/sniprun)

    • +
+
require('sniprun').setup({
+    binary_path="/path/to/your/sniprun",
+})
+
+
+
+
+
+
+
+

Usage

+

(you can of course see :help sniprun once installed for the complete list of commands, and :SnipInfo will have a decent share of useful information too)

+

You can do basically two things: run your code selection and stop it (in the rare occasions it crashes, it takes too long or sniprun crashes). You’ll probably be using only the first one, but the second can come in handy.

+
+

Running

+

Line mode: Place your cursor on the line you want to run, and type (in command mode):

+
:SnipRun
+
+
+

Running ‘live’ (aka running the current line as you’re typing is possible, but it’s very important to read the warnings about this, so I’m keeping the instructions in another chapter.

+

Bloc mode: Select the code you want to execute in visual mode and type in:

+

:'<,'>SnipRun

+

(the shorthand for :lua require'sniprun'.run('v'))

+

Operator mode:

+

Configure a mapping to <Plug>SnipRunOperator and combine it with movements to sniprun ‘text objects’. Every text-object will be rounded line-wise.

+
+
+

Stopping

+

ARGHHH I Sniprun’d an infinite loop (or anything that takes too long, or will crash, or anything)! +No worries, the second and last command will kill everything Sniprun ran so far:

+

:SnipReset

+

Alternatively, exit & re-enter Neovim.

+
+
+

Clearing

+

You may want to clear virtual text, close a terminal or a floating window created by Sniprun: for this, one command to rule them all:

+

:SnipClose

+
+
+

REPL-like behavior

+

Some languages, see support table, also have some kind of REPL behavior: you can expect your successive commands to behave like in a REPL interpreter, and to have ‘memory’ of lines you have previously sent to sniprun.

+

This is easier/cleaner to implement on interpreted languages, but compiled languages can have a REPL-like behavior too using dirty tricks, or through an intrepreter such as evcxr, but no compiled language has REPL behavior for now.

+

Many interpreted languages will have this behavior enabled or disabled by default, you can change this with the +repl_enable = { 'Interpreter_name', 'Another_one' } and repl_disable = {'Disabled_interpreter'} keys in the configuration. Relevant info is available in :SnipInfo / :SnipInfo <name>

+

If something does not work, or if the ‘memory’ is corrupted by bad code you can clear the REPL memory with :SnipReplMemoryClean that is a faster and less error-prone alternative to :SnipReset for this use case.

+
+
+
+

Configuration

+

Sniprun is a Lua plugin, but you don’t need the usual boilerplate: if you don’t need any special configuration, you don’t need to do anything at all.

+

However, if you want to change some options, you can add this snippet (the default config) to your configuration file and modify if at will (you can remove keys without issue to shorten your config, as the default values are overwritten on a key-by-key basis):

+
lua << EOF
+require'sniprun'.setup({
+  selected_interpreters = {},     --# use those instead of the default for the current filetype
+  repl_enable = {},               --# enable REPL-like behavior for the given interpreters
+  repl_disable = {},              --# disable REPL-like behavior for the given interpreters
+

+                                        --# but may not be always respected

Example, to use the interpreter ‘Python3_jupyter’ whenever possible [instead of the ‘Python3_original’ default], +lua require'sniprun'.setup({selected_interpreters = {'Python3_jupyter'}})

+

NOTE: Some interpreters have specific options and dependencies, such as what version / compiler to use: you cand find more about that with :SnipInfo <interpreter_name>. The use_on_filetypes key is available for every interpreter (as an interpreter_option) and allow sniprun to understand that your particular/custom filetypes are compatible with an interpreter.

Mappings & recommandations

+
    +

  • Map the run command to a simple command such as <leader>ff (or just f in visual mode)

    • +

  • Check SnipInfo & :SnipInfo <interpreter_name> to learn any quirk or tips about the language you’re interested in

    • +

  • The operator mapping allows you to combine movements with sniprun: with the suggested mapping, “<leader>f + j” will run sniprun on the current line + the line below.

    +

    (if you don’t know what is the leader key you can find a short explanation here).

    +
    • +
+
recommended mappings in lua +

+

vim.api.nvim_set_keymap('v', 'f', '<Plug>SnipRun', {silent = true})
+vim.api.nvim_set_keymap('n', '<leader>f', '<Plug>SnipRunOperator', {silent = true})
+vim.api.nvim_set_keymap('n', '<leader>ff', '<Plug>SnipRun', {silent = true})
+
+
+
+

+
recommended mappings in vimscript +

+

nmap <leader>ff <Plug>SnipRun
+nmap <leader>f <Plug>SnipRunOperator
+vmap f <Plug>SnipRun
+
+
+
+

+
    +

  • For interpreted languages with simple output, :%SnipRun (or a shortcut, wrapping it with let b:caret=winsaveview() and call winrestview(b:caret) in order to keep the cursor at the current position) may be a more convenient way to run your entire file. Example mapping :%SnipRun to F5: vim.keymap.set('n', '<F5>', ":let b:caret=winsaveview() <CR> | :%SnipRun <CR>| :call winrestview(b:caret) <CR>", {}), with my apologies for poor vimscript.

    • +
+

When running the whole file, SnipRun supports taking arguments on the command line: :%SnipRun 5 "yay" frictionlessly for interpreted languages, and compiled languages with entry point detection implemented (most of them).

+

While both shorthands and <Plug> are here to stay, it’s better practice to use the <Plug> style ones in your mappings or if using from another plugin.

+

Sniprun synergises exceptionnally well with plugins that help you creating print/debug statements, such as vim-printer.

+
+
+
+

Support levels and languages

+

As of writing, languages can be supported up to different extents:

+
    +

  • Unsupported/Untested : Community configs for the generic interpreter may support any language up to bloc level

    • +

  • Line : Code contained in a single line works, for example: print([x**2 for x in range(10)]) . Won’t work if you use a variable defined elsewhere.

    • +

  • Bloc : You can select any piece of code that is semantically correct (minus the eventual entry point) on its own (independently of indentation) in visual mode, and run it. A sniprun-able example, in Rust:

    • +
+
let alphabet = String::from\_utf8(
+    (b'a'..=b'z').chain(b'A'..=b'Z').collect()).unwrap();
+
+println!("-> {}", alphabet);
+
+
+
    +

  • Import : Support external imports, so you can test blocs of code that also depends on that external library import.

    • +
+
    +
  • File : Sniprun will recursively find the missing variable and function definitions to run your line of code(you don't have to select a bloc anymore). (no interpreter supports this yet) +
  • Project : Sniprun will detect the root of your project, and get the necessary code from files in your project, including relative imports. Basically everything you sniprun will 'work'. (no interpreter supports this yet) +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Your language is not officially supported ? The Generic interpreter can probably work with it !

+

Want (official) support for your language? Submit an issue,or even better, contribute (see CONTRIBUTING.md), it’s easy!

+

* (fake) REPL-like functionality, with potential unwanted side effects

+

** True REPL under the hood

+

*** if underlying language supports it

+
+
+

Live mode

+

The live mode hooks the SnipRun command to the TextChanged event, meaning that at every change to make to the buffer, the current line will be sent to sniprun for evaluation. This can mean a lot of times, especially if you type fast.

+

The result is a virtual text, displaying at the end of the current line that print the result (stdout) of the line. Nothing is displayed when the line is incomplete / incorrect, a bit like codi.

+
+

Warnings

+

The live mode will execute code you didn’t think really about (and by that I mean even less than usual) +Thus:

+
    +

  • Your code will get executed lots of times; check that your CPU can keep up. Even a slow 60wpm typing can make a Rust program recompile 3x per second, which is also different from sending 3 string/s to a running REPL.

    • +

  • Sniprun will try to execute even incomplete lines. You hadn’t finished typing that rm /path/to/arghhh ? sniprun’ not aware and removed the parent directory. Whoops. For these reasons, I strongly suggest to:

    +
      +

    • never run bash/shell with live mode

      • +

    • disable the live mode whenever your code modifies files or invoke system commands.

      • +
    +
    • +
+

If you’re running a REPL-capable interpreter, while it’ll probably work, mind that:

+
    +

  • the REPL will have to gulp a lot of incomplete code without crashing and stuff

    • +

  • typing b = b + 1 + 1 will increment b by more than 2 !! (since an intermediate b=b+1 is valid and thus changes b before b=b+1+1)

    • +
+
+
+

Configuration

+
You can set different display modes for live mode, with the config key
+```
+live_display = { "VirtualText", "TerminalOk"} --..or anything you want
+```
+
+
+
+
+

Enable and usage

+

live_mode_toggle='enable' in the config, (set to either ‘enable’ or ‘off’ - the default -, the ‘uncoherency’ is only to force people to come here and read the warnings in case some smart kid want to skip and just set it to ‘on’)

+

and then use the :SnipLive command and start coding.

+
+
+
+

API

+

You can use an API to communicate programmatically from sniprun, even though some goodies (combining motions with operators) may get lost in the process, and some others effects (fetching context and imports from the current buffer) may be undesirable.

+
local sa = require('sniprun.api')
+
+sa.run_range(r_start, r_end, <filetype>, <config>)
+sa.run_string(codestring, <filetype>, <config>)
+
+
+

run_range is a function that run the specified range of code from the current buffer and takes the following arguments:

+
    +

  • r_start, r_end (integers): (inclusive) line numbers of the range to run

    • +

  • filetype (string, optional): run the range as this language (:set ft? gives the filetype of the current buffer, which is used as the default)

    • +

  • config (dict, optional): override the default user config with this. (It may be interesting to provide only the display type ‘Api’ to retrieve the results without interference on the user’s UI)

    • +
+

run_string runs directly the provided string as code (but has still context from the current buffer etc…):

+
    +

  • codestring (string): the code to run

    • +

  • filetype (string, optional): run the codestring as ‘this language’

    • +

  • config (dict, optional): overrides the default user config

    • +
+
+
+

Known limitations

+

Due to its nature, Sniprun may have trouble with programs that :

+
    +

  • Mess with standart output / stderr

    • +

  • Need to read from stdin

    • +

  • Print incorrect UTF8 characters, or just too many lines

    • +

  • Access files; sniprun does not run in a virtual environment, it accesses files just like your own code do, but since it does not run the whole program, something might go wrong. Relative paths may cause issues, as the current working directory for sniprun will be somewhere in ~/.cache/sniprun, and relative imports may miss.

    • +
+
+
+

Troubleshooting

+

Begin by updating the plugin and running :SnipReset and then :checkhealth sniprun

+
    +

  • Silent fail: the sniprun binary may be incompatible with your distro/OS/arch. Use sh ./install.sh 1 as post-install to compile locally.

    • +
+
+
+

Contribute

+

It’s super easy: see the exhaustive (but simple I hope)(see CONTRIBUTING.md for starters). +I actually thought out the project structure so you only have to worry about one file (yours), when creating an interpreter. All you have to do is copy the example.rs interpreter and modify some parts to suit the language you wish to support.

Interpreter configuration

+

You can select an interpreter (with its name from :SnipInfo) if several of them support the language/filetype +(see use_on_filetype if necessary) and you want a specific one

+
lua << EOF
+require'sniprun'.setup({
+    selected_interpreters = { "Some_interpreter", "Python3_fifo"},
+})
+EOF
+
+
+

Many interpreters have REPL capabilities that are not enabled by default. You can turn this behavior on (or off) with the repl_enable and repl_disable keys, that similarly take interpreters names as arguments:

+
lua << EOF
+require'sniprun'.setup({
+    repl_enable = {"Python3_original", "Julia_jupyter"},   --# enable REPL-like behavior for the given interpreters
+    repl_disable = {"Lua_nvim"},          --# disable REPL-like behavior for the given interpreters
+})
+EOF
+
+
+
+
+

Common options

+

Every interpreter supports getting documentation via :SnipInfo <interpreter_name>

+

To specify interpreter options, you have to add the following to your sniprun config:

+
lua <<EOF
+require('sniprun').setup({
+
+    interpreter_options = {
+        <Interpreter_name> = {
+            some_specific_option = value,
+            some_other_option = other_value,
+        }
+    }
+  }, 
+})
+EOF
+
+
+

For example:

+
lua <<EOF
+require('sniprun').setup({
+
+    interpreter_options = {         --# interpreter-specific options, see doc / :SnipInfo <name>
+
+        --# use the interpreter name as key
+        GFM_original = {
+            use_on_filetypes = {"markdown.pandoc"}    --# the 'use_on_filetypes' configuration key is
+                                                      --# available for every interpreter
+        },
+        Python3_original = {
+            error_truncate = "auto"         --# Truncate runtime errors 'long', 'short' or 'auto'
+                                            --# the hint is available for every interpreter
+                                            --# but may not be always respected
+        }
+  }, 
+})
+EOF
+
+
+
+

The “use_on_filetypes” key

+

The use_on_filetypes key is implicitely an option of every interpreter

+
interpreter_options = {
+    GFM_original = {
+        use_on_filetypes = {"markdown.pandoc", "rstudio" }
+    }
+}
+
+
+
+
+

The “error_truncate” key

+

Also available for every interpreter if you don’t like how sniprun truncate some outputs by default (auto), but it will not have an effect on all interpreters.

+
interpreter_options = {
+    Python3_original = {
+        error_truncate = "auto"     --# Truncate runtime errors 'long', 'short' or 'auto'
+    }
+}, 
+
+
+
+
+
+

The interpreter/compiler keys

+

Almost every interpreter support either the “interpreter” or “compiler” key even if not explicitely documented, depending on whether they’re about an interpreter or compiled language.

+

example:

+
interpreter_options = {
+    Python3_original = {
+        interpreter = "python3.9"
+    }
+    Rust_original = {
+        compiler = "/home/user/bin/rustc-patched"
+    }
+}, 
+
+
+

You can see what interpreters/compilers are being used at any time by watching sniprun’s log for the line +“using compiler XXXX” or “using interpreter XXXX” when you run a snippet.

+

Exceptions:

+
    +

  • Scala_original has both interpreter and compiler keys that should be set consistently with each other

    • +

  • *_jupyter, Generic, GFM_original, Orgmode_original, and Neorg_original do not support any of these keys

Introduction

+

Sniprun has many different display modes, which you can combine and filter:

+

Display modes:

+
    +

  • “Classic”

    • +

  • “VirtualText”

    • +

  • “Terminal”

    • +

  • “TerminalWithCode”

    • +

  • “TempFloatingWindow”

    • +

  • “LongTempFloatingWindow”

    • +

  • “NvimNotify”

    • +

  • “Api”

    • +
+

Suffixes:

+
    +

  • “Ok” (only display sucessfull results)

    • +

  • “Err” (only display errors - compilation or runtime)

    • +
+

To configure which display mode(s) you want, just include their names (+suffix if wanted) in the display configuration key:

+
lua << EOF
+
+require('sniprun').setup({
+    display = {
+        "Classic",         -- will display both 'ok' & 'err' results in the command area
+        "VirtualTextOk",   -- will display only 'ok' results as virtual text on the line sent to sniprun
+    },
+})
+
+EOF
+
+
+
+
+

Available display modes

+
+

Classic

+

Results are displayed on the command area.

+

Pro/cons:

+
    +

  • Supports multi-lines results

    • +

  • Can (maybe) be copied

    • +

  • Ok/Err highlighting

    • +

  • Disappear on the next keypress

    • +
+
lua << EOF
+require'sniprun'.setup({
+  display = { "Classic" },
+})
+EOF
+
+
+

+
+
+

Virtual Text

+

Results are displayed as virtual text after the end of the line you sent to sniprun. (In case it’s a block, it goes at the end of the last line)

+

Pro/cons:

+
    +

  • Does not disappear (except after a SnipClose)

    • +

  • Ok/Err highlighting (outputs for ok and error results are highlighted with the groups SniprunVirtualTextOk and SniprunVirtualTextErr respectively)

    • +

  • Visually close to the code

    • +

  • No multiline possible. Results are shortened on a best-effort basis

    • +

  • Cannot be copied

    • +
+
lua <<EOF
+require'sniprun'.setup({
+  display = {
+    "VirtualText",
+  },
+})
+EOF
+
+
+

+
+
+

Temporary floating windows

+

Result are displayed in (temporary) floating windows. “LongTempFloatingWindow” will only display multiline messages, which allow for nice combinations with “VirtualText”

+

Pro/cons:

+
    +

  • Visually close to the code

    • +

  • Ok/Err highlighting (the highlight groups used are “SniprunFloatingWinOk” and “SniprunFloatingWinErr”)

    • +

  • Supports multiline results

    • +

  • Disappears on the next keypress

    • +

  • Cannot be copied

    • +
+
require'sniprun'.setup({
+  display = { "TempFloatingWindow" },
+})
+
+
+

+
+
+

Terminal

+

Results are displayed in a side panel

+

Pro/cons:

+
    +

  • Support multiline, and auto-scrolls when full

    • +

  • Results can be copied and do not disappear (except after a SnipClose)

    • +

  • Customizable width

    • +

  • No highlighting (only a ‘ok’ or ‘err’ message)

    • +

  • Can display the code that ran along with the result (with the “TerminalWithCode” variant)

    • +
+
lua << EOF
+require'sniprun'.setup({
+    display = { "Terminal" },
+    display_options = {
+        terminal_scrollback = vim.o.scrollback, -- change terminal display scrollback lines
+        terminal_line_number = false, -- whether show line number in terminal window
+        terminal_signcolumn = false, -- whether show signcolumn in terminal window
+        terminal_position = "vertical", --# or "horizontal", to open as horizontal split instead of vertical split
+        terminal_width = 45,          --# change the terminal display option width (if vertical)
+        terminal_height = 20,         --# change the terminal display option height (if horizontal)
+    },
+})
+EOF
+
+
+

if you experience wrapping of the header line ‘—- OK —’ due to the presence of a number column, you can (and should anyway) set

+
autocmd TermOpen * setlocal nonu
+
+
+

+

+
+
+

Notification

+

Results are displayed through the nvim-notify plugin (which must be installed).

+

Pro/cons:

+
    +

  • Supports multiline

    • +

  • Ok/Err highlighting

    • +

  • Disappears after 5s (timeout is customisable)

    • +
+
lua << EOF
+require'sniprun'.setup({
+   display = {"NvimNotify"},
+   display_options = {
+       notification_timeout = 5   -- in seconds
+   },
+})
+EOF
+
+
+

+
+
+

API display

+

Results are displayed through an user-provided function

+

You can register listeners that will be called upon (async) sniprun output:

+
local sa = require('sniprun.api')
+
+sa.register_listener(custom_function)
+
+
+

where custom function is a function that take one unique argument: a table which contains at least two entries:

+
    +

  • ‘status’ (a string that’s either ‘ok’ or ‘error’ for now, but your function should accept & manage other values)

    • +

  • ‘message’ (also a string, maybe be multiline)

    • +
+

(Simply put, registered functions are callbacks)

+

Thus, an example of such a function (imitating the ‘Classic’ display with ‘uwu’ tendencies) would be

+
local api_listener = function (d)
+    if d.status == 'ok' then
+        print("Nice uwu: ", d.message)
+    elseif d.status == 'error' then
+        print("Oh nyow! Somethuwuing went wyong: ", d.message)
+    else 
+        print("Whut is this myeow? I don't knyow this status type nyah")
+    end
+end
+
+sa.register_listener(api_listener)
+
+
+

(You must also enable the ‘Api’ display option, and in this particular case where things are printed to the command line area, disabling ‘Classic’ is recommended)

+

If your function requires to be manually closed (on SnipClose), you can register a closer the same way:

+
sa.register_closer(custom_function)
+

Bash original

+

Beware of Bash_original, as it runs as script on your system, with access to your ENV variables and PATH etc…

remove a file from absolute path will succeed!

C original

+

gcc is recommended, for that it’s able to detect, compile and run nested functions, however you can change the default compiler with:

+
require'sniprun'.setup({
+    interpreter_options = {
+        C_original = {
+             compiler = "clang"
+            }
+        }
+    }
+})
+
+
+

If you run with GCC, Sniprun will be able to run function + code in the same snippet, or functions + main() function regardlessly,but only the latter is supported by clang.

+

This interpreter will also only import (all) #include <…> but not any #include “…” (systems-wide include only, not the headers from your project, unless the environment variable $C_INCLUDE_PATH or $CPLUS_INCLUDE_PATH have been set). In this case, please make sure those variable cover ALL the paths needed to fetch every header file #include’d

+

the C_original interpreter will also make use of the following environment variables:

+
    +

  • $C_INCLUDE_PATH

    • +

  • $C_PLUS_INCLUDE_PATH

    • +

  • $LIBRARY_PATH

    • +

  • $CFLAGS

    • +
+

and will add them to the build options it uses. Please specify absolute path, and not relative ones!

+

Using a tool such as direnv may be really useful to set up those variables when you cd into your project’ directory.

Clojure fifo

+

This interpreter relies on clojure

+

The default interpreter command is clojure (or clojure -e "(clojure.main/repl :prompt (defn f[] ("")) )", that allow not displaying the repl prompt) but it can be changed via the configuration key

+

The defaults are equivalent to specifying:

+
require'sniprun'.setup({
+    interpreter_options = {
+        Clojure_fifo = {
+             interpreter_repl = "clojure -e \"(clojure.main/repl :prompt (defn f[] (\"\")) )\""
+             interpreter = "clojure"
+            }
+        }
+    }
+})
+
+
+

You can change those values, (to use clj for example ?) but it could break sniprun anytime

+
+

Blocked REPL

+

Clojure is a bit capricious and sometimes a typo will block forever (and a timeout will appear after 30s).

+

Don’t hesitate to SnipReset, even though it will lose all the currently in-memory variables

Limitations

+
    +

  • Will only look and load external imports (include) that are SYSTEM import; as sniprun does not have any way to differentiate between #include “math.h” (the system library) and #include “math2.h” (your custom header), it will NOT look for #include “….”, but only #include <….> (those are restricted to system libraries).

F# fifo

+
+

This interpreter relies on dotnet fsi being available and on your path

+

The default interpreter command is dotnet fsi --nologo but it can be changed via the configuration key

+
require'sniprun'.setup({
+    interpreter_options = {
+        FSharp_fifo = {
+             interpreter = "...."
+            }
+        }
+    }
+})
+
+
+
+
+

REPL (would solve slowness issues)

+

For now, REPL is broken due to dotnet fsi being capricious about its stdin.

+

I’ll explain rapidly how sniprun implement a REPL interpreter around named pipes (FIFOs).

+

The first time a fifo-based interpreter receive a run command, it forks to the background and executes ressources/init_repl.sh. +There is a lot of thing in that script but to replicate, you just have to:

+
    +

  • mkfifo pipe_in

    • +

  • create a launcher script:

    • +
+
#!/bin/bash
+/bin/cat pipe_in | dotnet fsi 
+
+# or replace 'dotnet fsi' by whatever you cant to try
+
+
+
    +

  • launch it in the background: bash ./launcher.sh &, (or bash ./launcher.sh > out.txt & to redirect stdout to out.txt like sniprun does)

    • +

  • ensure the pipe will stay open: sleep 3600 > pipe_in & (cat, exec 3> variations will also work)

    • +

  • echo "printfn \" hey \" " > pipe_in or cat hello_world.fsx > pipe_in

    • +

  • normally, the result should be printed in the terminal that ran the launcher, or in the out file.

    • +
+
+

The issue:

+

right now, dotnet fsi looks like it’s blocked by the first sleep > pipe_in… but something has to keep the pipe open or when it closes, the fsi REPL reading from that will exit.

+

I suspect the thing has something to do with interactive mode.

+

For example, python has a similar problem, but python -i (forced interactive mode, even if no terminal is detected because it runs in the background / its stdin was hijacked) works fine in the above example.

+

If you find something to replace dotnet fsi with, that exhibits the same correct behavior as python -i, sniprun REPL mode should work.

GFM original (Markdown)

+

the GFM_original (Github flavored markdown) can help run code blocs embedded in markdown.

+
+

example 1

+

```bash

+

echo “lol” # << you can run sniprun on this line

+

# or the whole visual selection following:

+

for i in {1..4};do

+

echo $i

+

done

+

```

+
+
+

example 2

+

``rust << running on this line will run the entire bloc

+

println!(“test”);

+

```

+

the language name must be there (otherwise the default * will be used) at the bloc start and has to match the github flavor syntax, and the underlying interpreter must be callable (no missing compiler etc…)

+

* python, but you can ofc configure that:

+
require'sniprun'.setup({
+    interpreter_options = {
+        GFM_original = { 
+            default_filetype = 'bash' -- default filetype (not github flavored markdown name)
+        }
+    }
+})
+
+
+

if GFM doesn’t include a flavor that matches the language you want, well it’s not really GFM anymore but you can but the filetype of the language you want, such as julia or lua

Generic

+

This interpreter allows you to support virtually any language, provided it’s not to strange, at up to bloc-level

+

If you’re trying to override an already-supported language, add Generic to the list of selected interpreters:

+
require'sniprun'.setup({
+    selected_interpreters = { 'Generic' },
+})
+
+
+

to add support for, let’s say, python2

+
require'sniprun'.setup({
+    interpreter_options = {
+        Generic = {
+            error_truncate="long",                 -- strongly recommended to figure out what's going on
+            MyPython2Config = {                    -- any key name is ok
+                supported_filetypes = {"python2"}, -- mandatory
+                extension = ".py",                 -- recommended, but not mandatory. Sniprun use this to create temporary files
+
+                interpreter = "python2",           -- interpreter or compiler (+ options if any)
+                compiler = "",                     -- one of those MUST be non-empty
+                }
+            }
+        }
+    }
+})
+
+

to also add support for, let’s suppose it wasn’t officially supported, C

+            }
+        },
+
+    -- other sniprun options, for example:
+    selected_interpreters = {"Generic"}
+})
+
+
+
+

How the generic interpreter works

+
+

For interpreted languages (“interpreter” is set)

+
    +

  1. Sniprun receive a snippet of code to run

    2. +

  2. The snippet gets surrounded by boilerplate_pre and boilerplate_post

    3. +

  3. The whole thing is written to a file with the given extension, named <exe_name>_src.<extension>

    4. +

  4. Sniprun runs <interpreter> <file>.<extension> and displays the stdout/stderr

    5. +
+
+
+

For compiled languages (“compiler” is set)

+
    +

  1. Sniprun receive a snippet of code to run

    2. +

  2. The snippet gets surrounded by boilerplate_pre and boilerplate_post

    3. +

  3. The whole thing is written to a temporary file with the given extension, named <exe_name>_src.<extension>

    4. +

  4. Sniprun runs <compiler>  <exe_name>_src.<extension> , and if this has a non-success status, displays the stderr

    5. +

  5. Sniprun runs ./<exe_name> and displays the stdout/stderr

    6. +

Julia jupyter

+

The setup for the julia_jupyter interpreter is quite convoluted:

+

Indeed, the Julia jupyter kernel MUST be started before Sniprun can run (and there is even a consequent delay since the kernel is so slow to start).

+

You should start a julia jupyter kernel with the following command: + jupyter-kernel --kernel=julia-1.5 --KernelManager.connection_file=$HOME/.cache/sniprun/julia_jupyter/kernel_sniprun.json

+

(adapt to your XDG_CACHE location if you’re on Mac)

+

You manage kernel startup AND shutodwn manually. Why? There is a terrible data race if sniprun does it. Python_jupyter works, julia doesn’t. That’s about it.

+

If you want to use another kernel location, post a feature request at github.com/michaelb/sniprun and i’ll see what I can do.

Julia original

+

Simply needs the ‘julia’ executable

+

REPL mode can be activated with this configuration

+
require'sniprun'.setup({
+    repl_enable = {'Julia_original'},
+})
+
+
+

Julia_original supports several interpreter options, such as the interpreter executable (absolute path or command in PATH, by default “julia”), and the ‘project’ (will be passed as –project=… to the executed command)

+
require('sniprun').setup({
+    interpreter_options = {
+        Julia_original = {
+            project="." --# either a fixed absolute path, or "." for nvim's current directory (from echo getcwd()  )

Lua_nvim

+

Limitations:

+

This interpreter works inherently in a pseudo-REPL mode and this can’t be disabled.

+

Essentially, you can expect REPL behavior when running line-by-line of bloc-by-bloc lua script:

+
a = 4 
+b = 6
+print(a+5) -- <- 9
+
+a = 0
+
+print(a + b) -- <- 6
+
+
+

HOWEVER, if you define a ‘local’ variable, it won’t be available in subsequent calls

+
local a = 5
+
+print(a) -- <- nil

Lua original

+

Limitation/feature

+

IF

+
    +

  • your code selection contains “nvim’ or “vim”, even in comments,

    • +

  • you haven’t explicitely selected Lua_original

    • +

  • your code snippet fails

    • +
+

THEN

+

Sniprun will use the lua-nvim interpreter instead of the normal ‘lua’ one.

Mathematica original

+
+

QuickStart

+

Check that WolframKernel and pkill are installed and on your path.

+

Then, the setup 99% of people want:

+
lua require'sniprun'.setup({
+    repl_enable = {'Mathematica_original'},
+    interpreter_options = {
+         Mathematica_original = {
+            use_javagraphics_if_contains = {'Plot'}, -- a pattern that need <<JavaGraphics
+        },
+    },
+})
+
+
+
+
+

Enabling graphics

+

You can specify whether the <<JavaGraphics` command ought to be issued before running a snippet that contains some patterns, like ‘Plot’. Enabling this may create a significant delay when the graphics are switched to that mode.

+
lua require'sniprun'.setup({
+    interpreter_options = {
+        Mathematica_original = {
+            use_javagraphics_if_contains = {'Plot', 'SomeCustomPlt'}, -- a pattern that need <<JavaGraphics
+            keep_plot_open_for = 3600,    -- a positive integer -> how many seconds to keep the plot window open
+        },
+    },
+})
+
+
+

This can be useful if you didn’t already use the construct:

+

Plot[Sin[x], {x, 0, 10}, DisplayFunction -> CreateDialog]

+

If your selection contains a Plot (or matching pattern), in non-REPL mode Mathematica_original will never return (in order to keep the graph window open), this means other statements will not return output.

+

As a general rule of thumb, in non-REPL mode, either sniprun a Plot or normal statements

+
+ +
+

Quirks of REPL-mode

+

Enabling REPL for mathematica will launch a WolframKernel instance in the background. This session will close when the last neovim instance quits, but is only usable by one neovim instance. +I hope you only need to sniprun mathematica snippets in one neovim instance, because anything else will probably crash.

+

In REPL-mode, your first SnipRun command of the neovim instance is used to start the REPL kernel, and the selection is discarded. You’ll have to re-run it, sorry, but that’s the only way for now.

+

In REPL-mode, just like in the normal interpreter, suffix your expressions with ‘;’ if you don’t want them to output something. I strongly recommend to suffix Plots with ‘;’

+
+
+

Troubleshooting

+
    +

  • No valid password found

    +
      +

    • For some reason, WolframKernel doesn’t like being launched in the background if there is arleady a WolframKernel instance running. You can close your own, or killall -9 WolframKernel to kill all the WolframKernel still running, and re-open neovim. This will also close the kernels you’ve launched yourself!

+

Neorg original

+

the Neorg_original interpreter helps you running code blocs defined in neorg code blocs delimiters

+

inline, switches and headers are not supported/ignored

+
+

example 1

+
#name demo
+@code bash
+
+echo "lol"  # << you can run sniprun on this line
+
+
+
+\# or the whole visual selection following:
+
+for i in {1..4};do
+
+echo $i
+
+done
+@end
+
+
+
+
+
+

example 2

+
#name demo_run_whole_bloc         << running on this line or the line below will run the entire bloc
+@code rust                        
+
+println!("test");
+println!("test2");
+@end
+
+
+

Even though it is possible to have empty lines in between the #name tag and the @code block for this plugin this doesn’t work. The #name has to be in the line directly above the @code block

+
#name name_tag_not_working        << this #name tag doesn't run the code below 
+
+
+@code rust                        
+
+println!("test");
+println!("test2");
+@end
+
+
+
+

the language name must be there (otherwise the default * will be used) at the bloc start and has to match the language name or the filetype associated

+

* python, but you can ofc configure that:

+
require'sniprun'.setup({
+    interpreter_options = {
+        Neorg_original = { 
+            default_filetype = 'bash' -- default filetype/language name

+
#name mycodebloc 
+@code rust                        
+println!("test");
+@end
+
+
+

running :%SnipRun mycodebloc will run this code bloc (and any code bloc named similarly, case-insensitively)

+

running :%SnipRun without any further arguments will run all the code blocs

OCaml fifo

+

This interpreter relies on ocaml by default, but has been confirmed to work with utop in normal (non-REPL) mode.

Prolog original

+

This interpreter is currently a work in progress and is probably not usable

+

The Prolog interpreter supports setting a different compiler/interpreter for prolog such as swi (‘swipl’)

+

you can set it with the following key:

+
require'sniprun'.setup({

Python3 fifo

+

This is a pipe-based implementation that has some quirks:

+

You have to run sniprun once before being able to send code snippets to it (configure an autocmd?)

+

A python REPL is launched in the background and won’t quit till you exit neovim.

+

This interpreter only works in REPL-mode, and is not the default for Python files, so to use it you should configure it as following:

+
require'sniprun'.setup({
+    selected_interpreters = { 'Python3_fifo' },
+    repl_enable = {'Python3_fifo'},
+})
+
+
+

if a snippet produce an error important enough to crash the interpreter, you may be required to re-launch the kernel (with a SnipRun)

+

setting a custom python interpreter and venv is also supported

+
require'sniprun'.setup({
+    interpreter_options = {
+        Python3_fifo = {
+            interpreter = "python3.9",

Python3 jupyter

+

Unless you really really need this (for Ipython), I would strongly advise for the Python3_fifo interpreter which has +way less potential issues

+
+

Dependencies

+
    +

  • jupyter

    • +
+

(more specifically, you must be able to run jupyter-kernel and jupyter-console from the command line)

+
+
+

Notes

+

(As there is a different interpreter for Python, you may want to force the selection of Python3_jupyter with:)

+
require'sniprun'.setup({
+    selected_interpreters={'Python3_jupyter'}
+})
+
+
+
+
+

Limitations

+

The code runs on a separate jupyter python3 kernel which will NOT interefere with your own running kernels.

+

However, mind that the usual limitations of such kernels still apply: max duration of execution, etc… but you probably don’t have to pay too much attention to this.

+

The jupyter kernel also has a substantial overhead when it comes to running code, in addition to (well-managed) imports, that means the Python3_jupyter interpreter may feel a bit slow compared to others, when the REPL functionnaluty relying on it.

Python3 original

+

To get the REPL behaviour (inactive by default) working, you need to isntall the klepto python package: pip install --user klepto

+

Then, to enable the REPL behavior for python in your config file

+
require'sniprun'.setup({
+    repl_enable = {'Python3_original'}
+})
+
+
+

HOWEVER, if you’re interested in a very stable and solid REPL python interpreter, to process bigger amount of data or import some exotic modules (not supported by klepto), get a look at the Python3_fifo interpreter.

+

With the REPL enabled, sniprunning a * (star) import from module import * may not work, indeed the imports needs to be correctly saved/loaded by klepto. klepto manages variables, functions and modules but very special things may fail.

+

Without REPL enabled, your python snip’s will be executed faster (and not increasingly slower) and the correctness/cleanliness of the inner working is garanteed. By setting this, you can be sure your snip’s will run free of side-effects and anything you would not want.

+

With or without REPL, the star imports may also not be automatically fetched, even though normal imports will be. Python3_original has the ‘Import’ support level but that won”t work with star import, and I don’t think we’ll be able to make a workaround due to the philosophy ‘run only what’s necessary’ of sniprun.

+

To use a custom python interpreter ( maybe python2, or a particular version?) you can provide the following interpreter options:, using a venv is also supported (provide one or several relative paths “../venv” etc.. may be necessary if you didn’t open neovim at the root of the project)

+
require'sniprun'.setup({
+    interpreter_options = {
+        Python3_original = {
+            interpreter = "python3.9",
