TLCR Build Status

tlcr is a simple terminal-based client for TLDR pages, written in Crystal.

TLDR pages is a collection of simplified and community-driven man pages.


tlcr is under development. It works and can be used, but testing and reporting issues is appreciated.


  • Simple CLI
  • Colorized Markdown rendering in the terminal
  • Local file based cache
  • Bash completion
  • No dependencies
  • Local file rendering (for authors)
  • Batch download



brew tap porras/tap
brew install tlcr

Or, if you want to install the latest, unreleased version:

brew tap porras/tap
brew install tlcr --HEAD



There is an APT repository with signed packages of the latest tlcr version. To setup this repo and install tlcr, run the following commands (as root or with sudo):

apt-key adv --keyserver --recv-keys ED2715FE
echo "deb packages main" > /etc/apt/sources.list.d/
apt-get update
apt-get install tlcr

Other distributions

See how to install from source below.

From source

If there are no binary packages for your OS version, you can install tlcr building it from source. See Development for instructions.


Usage: tlcr [options] [command]
    -u, --update                     Force update (default: cache for 30 days)
    -r, --render                     Render local file (for authors)
    -d, --download                   Download the whole TLDR archive
    -h, --help                       Show this help


Displaying a page:

$ tlcr ls

Displaying a page, forcing its download (and the download of the index):

$ tlcr --update ls

Displaying a page from a local file (useful if you're contributing to TLDR pages and want to have a look before submitting a patch):

$ tlcr --render tldr/pages/common/

Downloading the whole archive (it will download everything at once and store it in the normal cache, where it will expire, in the normal way, after 30 days, when it can be downloaded either completely again, or on demand page by page, as normal):

$ tlcr --download

Bash completion

After having tlcr installed, add this to your .bashrc:

eval "$(tlcr --completion)"

You don't need this if you installed via Homebrew (it's automatic).


You need Crystal 0.19.x installed (it might work with older or newer versions, but that's the one that's tested).

After checking out the repo (or decompressing the tarball with the source code), run shards to get the development dependencies, and run crystal build (crystal build --release if you intend to install it for real use). The tlcr binary generated in the directory can be copied anywhere in your $PATH.


  1. Fork it ( )
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create a new Pull Request
