# asciinema [![Build Status](https://travis-ci.org/asciinema/asciinema.svg?branch=master)](https://travis-ci.org/asciinema/asciinema) Terminal session recorder and the best companion of [asciinema.org](https://asciinema.org). [![demo](https://asciinema.org/a/624fjx2rx7k3pctdozw7m8b24.png)](https://asciinema.org/a/624fjx2rx7k3pctdozw7m8b24?autoplay=1) ## Installation ### Using package manager asciinema is available in repositories of most popular package managers on Mac OS X, Linux and FreeBSD. Look for package named `asciinema`. See the [list of available packages](https://asciinema.org/docs/installation). ### Building from source To build asciinema from source you need to have [Go development toolchain](http://golang.org/doc/install) installed. #### With `go get` You can use `go get` to fetch the source, build and install asciinema at `$GOPATH/bin/asciinema` in one go: go get github.com/asciinema/asciinema #### With `make` Download the source code into your `$GOPATH`: mkdir -p $GOPATH/src/github.com/asciinema git clone https://github.com/asciinema/asciinema.git $GOPATH/src/github.com/asciinema/asciinema Build the binary: cd $GOPATH/src/github.com/asciinema/asciinema make build This will produce asciinema binary at `$GOPATH/src/github.com/asciinema/asciinema/bin/asciinema`. To install it system wide (to `/usr/local`): sudo make install If you want to install it in other location: PREFIX=/the/prefix make install ## Usage asciinema is composed of multiple commands, similar to `git`, `rails` or `brew`. When you run `asciinema` with no arguments help message is displayed showing all available commands with their options. ### `rec [filename]` __Record terminal session.__ This is the single most important command in asciinema, since it is how you utilize this tool's main job. By running `asciinema rec [filename]` you start a new recording session. The command (process) that is recorded can be specified with `-c` option (see below), and defaults to `$SHELL` which is what you want in most cases. Recording finishes when you exit the shell (hit Ctrl+D or type `exit`). If the recorded process is not a shell then recording finishes when the process exits. If the `filename` argument is given then the resulting recording (called [asciicast](doc/asciicast-v1.md)) is saved to a local file. It can later be replayed with `asciinema play ` and/or uploaded to asciinema.org with `asciinema upload `. If the `filename` argument is omitted then (after asking for confirmation) the resulting asciicast is uploaded to asciinema.org for further playback in a web browser. `ASCIINEMA_REC=1` is added to recorded process environment variables. This can be used by your shell's config file (`.bashrc`, `.zshrc`) to alter the prompt or play a sound when shell is being recorded. Available options: * `-c, --command=` - Specify command to record, defaults to $SHELL * `-t, --title=` - Specify title of the asciicast * `-w, --max-wait=<sec>` - Reduce recorded terminal inactivity to max <sec> seconds * `-y, --yes` - Answer yes to all prompts (e.g. upload confirmation) ### `play <filename>` __Replay recorded asciicast in a terminal.__ This command replays given asciicast (as recorded by `rec` command) directly in your terminal. When "-" is passed as a filename the asciicast is read from stdin. For example: curl -sL https://asciinema.org/a/21310.json | asciinema play - NOTE: it is recommended to run it in a terminal of dimensions not smaller than the one used for recording as there's no "transcoding" of control sequences for new terminal size. Available options: * `-w, --max-wait=<sec>` - Reduce replayed terminal inactivity to max <sec> seconds ### `upload <filename>` __Upload recorded asciicast to asciinema.org site.__ This command uploads given asciicast (as recorded by `rec` command) to asciinema.org for further playback in a web browser. `asciinema rec demo.json` + `asciinema play demo.json` + `asciinema upload demo.json` is a nice combo for when you want to review an asciicast before publishing it on asciinema.org. ### `auth` __Assign local API token to asciinema.org account.__ On every machine you install asciinema recorder, you get a new, unique API token. This command connects this local token with your asciinema.org account, and links all asciicasts recorded on this machine with the account. This command displays the URL you should open in your web browser. If you never logged in to asciinema.org then your account will be created when opening the URL. NOTE: it is __necessary__ to do this if you want to __edit or delete__ your recordings on asciinema.org. You can synchronize your config file (which keeps the API token) across the machines but that's not necessary. You can assign new tokens to your account from as many machines as you want. ## Configuration file asciinema uses a config file to keep API token and user settings. In most cases the location of this file is `$HOME/.config/asciinema/config`. When you first run `asciinema`, local API token is generated and saved in the file (unless the file already exists). It looks like this: [api] token = d5a2dce4-173f-45b2-a405-ac33d7b70c5f There are several options you can set in this file. Here's a config with all available options set: [api] token = d5a2dce4-173f-45b2-a405-ac33d7b70c5f url = https://asciinema.example.com [record] command = /bin/bash -l maxwait = 2 yes = true [play] maxwait = 1 The options in `[api]` section are related to API location and authentication. To tell asciinema recorder to use your own asciinema site instance rather than the default one (asciinema.org), you can set `url` option. API URL can also be passed via `ASCIINEMA_API_URL` environment variable. The options in `[record]` and `[play]` sections have the same meaning as the options you pass to `asciinema rec`/`asciinema play` command. If you happen to often use either `-c`, `-w` or `-y` with these commands then consider saving it as a default in the config file. ### Configuration file locations In fact, the following locations are checked for the presence of the config file (in the given order): * `$ASCIINEMA_CONFIG_HOME/config` - if you have set `$ASCIINEMA_CONFIG_HOME` * `$XDG_CONFIG_HOME/asciinema/config` - on Linux, `$XDG_CONFIG_HOME` usually points to `$HOME/.config/` * `$HOME/.config/asciinema/config` - in most cases it's here * `$HOME/.asciinema/config` - created by asciinema versions prior to 1.1 The first one which is found is used. ## Contributing If you want to contribute to this project check out [Contributing](https://asciinema.org/contributing) page. ## Authors Developed with passion by [Marcin Kulik](http://ku1ik.com) and great open source [contributors](https://github.com/asciinema/asciinema/contributors) ## License Copyright © 2011-2015 Marcin Kulik.
