# tldr-node-client
[![NPM version][npm-image]][npm-url]
[![GitHub Action Build Status][gh-actions-image]][gh-actions-url]
[![Matrix chat][matrix-image]][matrix-url]
A `Node.js` based command-line client for [tldr](https://github.com/tldr-pages/tldr).
_tldr-node-client's output for the `tar` page, using a custom color theme_
## Installing
```bash
npm install -g tldr
```
## Usage
To see tldr pages:
- `tldr ` show examples for this command
- `tldr --platform=` show command page for the given platform
- `tldr --android ` show command page for Android
- `tldr --darwin ` show command page for darwin (macOS)
- `tldr --freebsd ` show command page for FreeBSD
- `tldr --linux ` show command page for Linux
- `tldr --macos ` show command page for macOS
- `tldr --netbsd ` show command page for NetBSD
- `tldr --openbsd ` show command page for OpenBSD
- `tldr --osx ` show command page for osx (macOS)
- `tldr --sunos ` show command page for SunOS
- `tldr --win32 ` show command page for win32 (Windows)
- `tldr --windows ` show command page for Windows
- `tldr --search ""` search all pages for the query
- `tldr --list` show all pages for current platform
- `tldr --list-all` show all available pages
- `tldr --random` show a page at random
- `tldr --random-example` show a single random example
- `tldr --markdown` show the original markdown format page
The client caches a copy of all pages locally, in `~/.tldr`.
There are more commands to control the local cache:
- `tldr --update` download the latest pages and generate search index
- `tldr --clear-cache` delete the entire local cache
As a contributor, you might also need the following commands:
- `tldr --render ` render a local page for testing purposes
Tldr pages defaults to showing pages in the current language of the operating system, or English if that's not available. To view tldr pages for a different language, set an environment variable `LANG` containing a valid [POSIX locale](https://www.gnu.org/software/gettext/manual/html_node/Locale-Names.html#Locale-Names) (such as `zh`, `pt_BR`, or `fr`) and then run the above commands as usual. In most `*nix` systems, this variable will already be set.
It is suggested that the `LANG` environment variable be set system-wide if this isn't already the case. Users without `sudo` access can set it locally in their `~/.profile`.
- `LANG=zh tldr `
For the list of available translations, please refer to the main [tldr](https://github.com/tldr-pages/tldr) repo.
## Configuration
You can configure the `tldr` client by adding a `.tldrrc` file in your HOME directory. You can copy the contents of the `config.json` file from the repo to get the basic structure to start with, and modify it to suit your needs.
The default color theme is the one named `"simple"`. You can change the theme by assigning a different value to the `"theme"` variable -- either to one of the pre-configured themes, or to a new theme that you have previously created in the `"themes"` section. Note that the colors and text effects you can choose are limited. Refer to the [chalk documentation](https://github.com/chalk/chalk#styles) for all options.
```json
{
"themes": {
"ocean": {
"commandName": "bold, cyan",
"mainDescription": "",
"exampleDescription": "green",
"exampleCode": "cyan",
"exampleToken": "dim"
},
"myOwnCoolTheme": {
"commandName": "bold, red",
"mainDescription": "underline",
"exampleDescription": "yellow",
"exampleCode": "underline, green",
"exampleToken": ""
}
},
"theme": "ocean"
}
```
If you regularly need pages for a different platform (e.g. Linux),
you can put it in the config file:
```json
{
"platform": "linux"
}
```
The default platform value can be overwritten with command-line option:
```shell
tldr du --platform=
```
As a contributor, you can also point to your own fork containing the `tldr.zip` file. The file is just a zipped version of the entire tldr repo:
```js
{
"repository": "http://myrepo/assets/tldr.zip"
}
```
By default, a cache update is performed anytime a page is not found for a command. To prevent this behavior,
you can set the configuration variable `skipUpdateWhenPageNotFound` to `true` (defaults to `false`):
```js
{
"skipUpdateWhenPageNotFound": true
}
```
## Command-line Autocompletion
Currently we only support command-line autocompletion for zsh
and bash. Pull requests for other shells are most welcome!
### zsh
It's easiest for
[oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh)
users, so let's start with that.
```zsh
mkdir -p $ZSH_CUSTOM/plugins/tldr
ln -s bin/completion/zsh/_tldr $ZSH_CUSTOM/plugins/tldr/_tldr
```
Then add tldr to your oh-my-zsh plugins,
usually defined in `~/.zshrc`,
resulting in something looking like this:
```zsh
plugins=(git tmux tldr)
```
Alternatively, using [zplug](https://github.com/zplug/zplug)
```zsh
zplug "tldr-pages/tldr-node-client", use:bin/completion/zsh
```
Fret not regular zsh user!
Copy or symlink `bin/completion/zsh/_tldr` to
`my/completions/_tldr`
(note the filename).
Then add the containing directory to your fpath:
```zsh
fpath=(my/completions $fpath)
```
### Bash
```bash
ln -s bin/completion/bash/tldr ~/.tldr-completion.bash
```
Now add the following line to our bashrc file:
```bash
source ~/.tldr-completion.bash
```
## FAQ
### Installation Issues
- If you are trying to install as non-root user (`npm install -g tldr`) and get something like:
```text
Error: EACCES: permission denied, access '/usr/local/lib/node_modules/tldr'
```
Then most probably your npm's default installation directory has improper permissions. You can resolve it by clicking [here](https://docs.npmjs.com/getting-started/fixing-npm-permissions)
- If you are trying to install as a root user (`sudo npm install -g tldr`) and get something like:
```shell
as root ->
gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/local/lib/node_modules/tldr/node_modules/webworker-threads/.node-gyp"
gyp WARN EACCES user "root" does not have permission to access the dev dir "/usr/local/lib/node_modules/tldr/node_modules/webworker-threads/.node-gyp/8.9.1"
```
You need to add the option `--unsafe-perm` to your command. This is because when npm goes to the postinstall step, it downgrades the permission levels to "nobody". Probably you should fix your installation directory permissions and install as a non-root user in the first place.
- If you see an error related to `webworker-threads` like:
```text
/usr/local/lib/node_modules/tldr/node_modules/natural/lib/natural/classifiers/classifier.js:32
if (e.code !== 'MODULE_NOT_FOUND') throw e;
```
Most probably you need to reinstall `node-gyp` and `webworker-threads`. Try this -
```shell
sudo -H npm uninstall -g tldr
sudo -H npm uninstall -g webworker-threads
npm install -g node-gyp
npm install -g webworker-threads
npm install -g tldr
```
For further context, take a look at this [issue](https://github.com/tldr-pages/tldr-node-client/issues/179)
#### Colors under Cygwin
Colors can't be shown under Mintty or PuTTY, because the dependency `colors.js` has a bug.
Please show support to [this pull request](https://github.com/Marak/colors.js/pull/154), so it can be merged.
Meanwhile, you can do one of the following to fix this issue:
- Add the following script to your shell's rc file (`.zshrc`, `.bashrc`, etc.): (RECOMMENDED)
```bash
tldr_path="$(which tldr)"
function tldr() {
eval "$tldr_path" $@ "--color"
}
```
- Add `alias tldr="tldr --color=true"` to your shell's rc file.
- Prepend `process.stdout.isTTY = true;` to `tldr.js` (NOT RECOMMENDED)
- Fix `colors.js`'s logic (NOT RECOMMENDED)
- Go to `%appdata%\npm\node_modules\tldr\node_modules\colors\lib\system\`
- Overwrite `supports-colors.js` with [supports-colors.js](https://raw.githubusercontent.com/RShadowhand/colors.js/master/lib/system/supports-colors.js) from my repo.
- Use `CMD.exe`.
