Adds a Run button to code blocks and shows the output right below, for JavaScript, Python, shell and more.
Why this one
- Output as it happens. Text appears while the program runs, and the same button turns into Stop.
- Stop really stops. It ends the script and anything the script started, so a forgotten
sleepor server does not keep running. - A time limit and an output limit. Runs end after 30 seconds by default, and very long output is cut with a note saying how much was dropped.
- Your own tools. Each language uses the program you already have, and you can point it at a full path or add flags, such as
python3 -u. - Asks once. Code runs with your own permissions, so the first Run explains that and waits for a yes.
Usage
In reading view, every block in a supported language gets a Run button. Click it: the output appears below the block, with a line saying how it ended (done, exited with an error code, stopped, or past the time limit).
In editing view, put the cursor in a block and run Run code block at cursor and insert its output from the command palette. The output is written as an output block right under the code, and running again replaces it, so it never piles up.
Stop all running code is also in the command palette while something is running.
Supported fences (each needs its program installed and on your PATH):
| Language | Fence names | Program |
|---|---|---|
| JavaScript | js, javascript, node |
node |
| TypeScript | ts, typescript |
node (type stripping, Node 22.6 or later) |
| Python | python, py, python3 |
python3 (python on Windows) |
| Bash | bash, sh, shell |
bash |
| Zsh | zsh |
zsh |
| PowerShell | powershell, ps1, pwsh |
pwsh (powershell on Windows) |
| Ruby, PHP, Perl, Lua, R, Go | ruby/rb, php, perl/pl, lua, r, go/golang |
ruby, php, perl, lua, Rscript, go run |
If a program is not found, the line under the block says which one and where to set its path.
Settings
Time limit, output limit, whether programs start in the vault root or in the note's folder, and a program override for each language.
Safety
Code runs on your computer with your permissions, exactly as if you had typed it in a terminal. It can read, change or delete files and use the network. Only run code you wrote or trust, including code in notes from other people. Nothing is run unless you click Run or use the command, and the plugin does not send anything anywhere.
Desktop only: it needs Node's child processes, which mobile does not have.
Installation
In Obsidian, open Settings → Community plugins → Browse and search for "Run Code Blocks".
