# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, sex characteristics, gender identity and expression,
level of experience, education, socio-economic status, nationality, personal
appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at mikefarah@gmail.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

a lightweight and portable command-line YAML processor. `yq` uses [jq](https://github.com/stedolan/jq) like syntax but works with yaml files as well as json. It doesn't yet support everything `jq` does - but it does support the most common operations and functions, and more is being added continuously.
a lightweight and portable command-line YAML processor
yq is written in go - so you can download a dependency free binary for your platform and you are good to go! If you prefer there are a variety of package managers that can be used as well as Docker and Podman, all listed below.
The aim of the project is to be the [jq](https://github.com/stedolan/jq) or sed of yaml files.
## Quick Usage Guide
Read a value:
```bash
yq e '.a.b[0].c' file.yaml
```
## Major upgrade - V3 beta is out!
Pipe from STDIN:
```bash
cat file.yaml | yq e '.a.b[0].c' -
```
This addresses a number of features requests and issues that have been raised :)
Update a yaml file, inplace
```bash
yq e -i '.a.b[0].c = "cool"' file.yaml
```
Currently only available only available as a [binary release here](https://github.com/mikefarah/yq/releases/tag/3.0.0-beta) or via docker mikefarah/yq:3.0.0-beta!
Update using environment variables
```bash
NAME=mike yq e -i '.a.b[0].c = strenv(NAME)' file.yaml
```
It does have a few breaking changes listed on the [release page](https://github.com/mikefarah/yq/releases/tag/3.0.0-beta)
Merge multiple files
```
yq ea '. as $item ireduce ({}; . * $item )' path/to/*.yml
```
Looking forward to feedback - once this is out of beta it will be added to the remaining package managers, and be the default version downloaded (and merged into master).
Multiple updates to a yaml file
```bash
yq e -i '
.a.b[0].c = "cool" |
.x.y.z = "foobar" |
.person.name = strenv(NAME)
' file.yaml
```
See the [documentation](https://mikefarah.gitbook.io/yq/) for more.
V2 will no longer have any new features added, and will be moved to a branch (v2). It will have limited maintenance for bugs for a few months.
## Install
### [Download the latest binary](https://github.com/mikefarah/yq/releases/latest)
### wget
Use wget to download the pre-compiled binaries:
#### Compressed via tar.gz
```bash
wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY}.tar.gz -O - |\
tar xz && mv ${BINARY} /usr/bin/yq
```
#### Plain binary
```bash
wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq &&\
chmod +x /usr/bin/yq
```
For instance, VERSION=v4.2.0 and BINARY=yq_linux_amd64
### MacOS / Linux via Homebrew:
Using [Homebrew](https://brew.sh/)
### On MacOS:
```
brew install yq
```
### Linux via snap:
### On Ubuntu and other Linux distros supporting `snap` packages:
```
snap install yq
```
#### Snap notes
`yq` installs with [_strict confinement_](https://docs.snapcraft.io/snap-confinement/6233) in snap, this means it doesn't have direct access to root files. To read root files you can:
`yq` installs with with [_strict confinement_](https://docs.snapcraft.io/snap-confinement/6233) in snap, this means it doesn't have direct access to root files. To read root files you can:
```
sudo cat /etc/myfile | yq e '.a.path' -
sudo cat /etc/myfile | yq r - a.path
```
And to write to a root file you can either use [sponge](https://linux.die.net/man/1/sponge):
```
sudo cat /etc/myfile | yq e '.a.path = "value"' - | sudo sponge /etc/myfile
sudo cat /etc/myfile | yq w - a.path value | sudo sponge /etc/myfile
```
or write to a temporary file:
```
sudo cat /etc/myfile | yq e '.a.path = "value"' | sudo tee /etc/myfile.tmp
sudo cat /etc/myfile | yq w - a.path value | sudo tee /etc/myfile.tmp
sudo mv /etc/myfile.tmp /etc/myfile
rm /etc/myfile.tmp
```
### Run with Docker or Podman
#### Oneshot use:
```bash
docker run --rm -v "${PWD}":/workdir mikefarah/yq <command> [flags] [expression ]FILE...
### On Ubuntu 16.04 or higher from Debian package:
```
sudo add-apt-repository ppa:rmescandon/yq
sudo apt update
sudo apt install yq -y
```
### or, [Download latest binary](https://github.com/mikefarah/yq/releases/latest) or alternatively:
```
GO111MODULE=on go get github.com/mikefarah/yq/v2
```
## Run with Docker
Oneshot use:
```bash
podman run --rm -v "${PWD}":/workdir mikefarah/yq <command> [flags] [expression ]FILE...
docker run --rm -v ${PWD}:/workdir mikefarah/yq yq [flags] <command> FILE...
```
#### Pipe in via STDIN:
You'll need to pass the `-i\--interactive` flag to docker:
Run commands interactively:
```bash
cat myfile.yml | docker run -i --rm mikefarah/yq e . -
```
```bash
cat myfile.yml | podman run -i --rm mikefarah/yq e . -
```
#### Run commands interactively:
```bash
docker run --rm -it -v "${PWD}":/workdir --entrypoint sh mikefarah/yq
```
```bash
podman run --rm -it -v "${PWD}":/workdir --entrypoint sh mikefarah/yq
docker run --rm -it -v ${PWD}:/workdir mikefarah/yq sh
```
It can be useful to have a bash function to avoid typing the whole docker command:
```bash
yq() {
docker run --rm -i -v "${PWD}":/workdir mikefarah/yq "$@"
docker run --rm -i -v ${PWD}:/workdir mikefarah/yq yq $@
}
```
```bash
yq() {
podman run --rm -i -v "${PWD}":/workdir mikefarah/yq "$@"
}
```
#### Running as root:
`yq`'s container image no longer runs under root (https://github.com/mikefarah/yq/pull/860). If you'd like to install more things in the container image, or you're having permissions issues when attempting to read/write files you'll need to either:
```
docker run --user="root" -it --entrypoint sh mikefarah/yq
```
```
podman run --user="root" -it --entrypoint sh mikefarah/yq
```
Or, in your Dockerfile:
```
FROM mikefarah/yq
USER root
RUN apk add bash
USER yq
```
### GitHub Action
```
- name: Set foobar to cool
uses: mikefarah/yq@master
with:
cmd: yq eval -i '.foo.bar = "cool"' 'config.yml'
```
See https://mikefarah.gitbook.io/yq/usage/github-action for more.

- Deep read a yaml file with a given path
- Update a yaml file given a path
- Update a yaml file given a script file
- Update creates any missing entries in the path on the fly
- Create a yaml file given a deep path and value
- Create a yaml file given a script file
- Prefix a path to a yaml file
- Convert from json to yaml
- Convert from yaml to json
- Pipe data in by using '-'
- Merge multiple yaml files where each additional file sets values for missing or null value keys.

```
yq is a lightweight and portable command-line YAML processor. It aims to be the jq or sed of yaml files.
Usage:
yq [flags]
yq [command]
Available Commands:
eval Apply the expression to each document in each yaml file in sequence
eval-all Loads _all_ yaml documents of _all_ yaml files and runs expression once
help Help about any command
shell-completion Generate completion script
delete yq d [--inplace/-i] [--doc/-d index] sample.yaml a.b.c
help Help about any command
merge yq m [--inplace/-i] [--doc/-d index] [--overwrite/-x] [--append/-a] sample.yaml sample2.yaml
new yq n [--script/-s script_file] a.b.c newValue
prefix yq p [--inplace/-i] [--doc/-d index] sample.yaml a.b.c
read yq r [--doc/-d index] sample.yaml a.b.c
write yq w [--inplace/-i] [--script/-s script_file] [--doc/-d index] sample.yaml a.b.c newValue
Flags:
-C, --colors force print with colors
-e, --exit-status set exit status if there are no matches or null or false is returned
-f, --front-matter string (extract|process) first input as yaml front-matter. Extract will pull out the yaml content, process will run the expression against the yaml content, leaving the remaining data intact
--header-preprocess Slurp any header comments and seperators before processing expression. This is a workaround for go-yaml to persist header content (default true)
-h, --help help for yq
-I, --indent int sets indent level for output (default 2)
-i, --inplace update the yaml file inplace of first yaml file given.
-M, --no-colors force print with no colors
-N, --no-doc Don't print document separators (---)
-n, --null-input Don't read input, simply evaluate the expression given. Useful for creating yaml docs from scratch.
-o, --output-format string [yaml|y|json|j|props|p] output format type. (default "yaml")
-P, --prettyPrint pretty print, shorthand for '... style = ""'
--unwrapScalar unwrap scalar, print the value with no quotes, colors or comments (default true)
-v, --verbose verbose mode
-V, --version Print version information and quit
-h, --help help for yq
-t, --trim trim yaml output (default true)
-v, --verbose verbose mode
-V, --version Print version information and quit
Use "yq [command] --help" for more information about a command.
```
## Known Issues / Missing Features
- `yq` attempts to preserve comment positions and whitespace as much as possible, but it does not handle all scenarios (see https://github.com/go-yaml/yaml/tree/v3 for details)
- Powershell has its own...[opinions on quoting yq](https://mikefarah.gitbook.io/yq/usage/tips-and-tricks#quotes-in-windows-powershell)
See [tips and tricks](https://mikefarah.gitbook.io/yq/usage/tips-and-tricks) for more common problems and solutions.

<h1>Convert</h1>
<h3 id="yaml-to-json">Yaml to Json<a class="headerlink" href="#yaml-to-json" title="Permanent link">&para;</a></h3>
<p>To convert output to json, use the --tojson (or -j) flag. This can only be used with the read command.</p>
<p>Given a sample.yaml file of:</p>
<pre><code class="yaml">b:
c: 2
</code></pre>
<p>then</p>
<pre><code class="bash">yq r -j sample.yaml b.c
</code></pre>
<p>will output</p>
<pre><code class="json">{&quot;b&quot;:{&quot;c&quot;:2}}
</code></pre>
<h3 id="json-to-yaml">Json to Yaml<a class="headerlink" href="#json-to-yaml" title="Permanent link">&para;</a></h3>
<p>To read in json, just pass in a json file instead of yaml, it will just work :)</p>
<p>e.g given a json file</p>
<pre><code class="json">{&quot;a&quot;:&quot;Easy! as one two three&quot;,&quot;b&quot;:{&quot;c&quot;:2,&quot;d&quot;:[3,4]}}
</code></pre>
<p>then</p>
<pre><code class="bash">yq r sample.json
</code></pre>
<p>will output</p>
<pre><code class="yaml">a: Easy! as one two three
b:
c: 2
d:

<h1>Create</h1>
<p>Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file. Currently this does not support creating multiple documents in a single yaml file.</p>
<pre><code>yq n &lt;path&gt; &lt;new value&gt;
</code></pre>
<h3 id="creating-a-simple-yaml-file">Creating a simple yaml file<a class="headerlink" href="#creating-a-simple-yaml-file" title="Permanent link">&para;</a></h3>
<pre><code class="bash">yq n b.c cat
</code></pre>
<p>will output:</p>
<pre><code class="yaml">b:
c: cat
</code></pre>
<h3 id="creating-using-a-create-script">Creating using a create script<a class="headerlink" href="#creating-using-a-create-script" title="Permanent link">&para;</a></h3>
<p>Create scripts follow the same format as the update scripts.</p>
<p>Given a script create_instructions.yaml of:</p>
<pre><code class="yaml">b.c: 3
b.e[+].name: Howdy Partner
</code></pre>
<p>then</p>
<pre><code class="bash">yq n -s create_instructions.yaml
</code></pre>
<p>will output:</p>
<pre><code class="yaml">b:
c: 3
e:
- name: Howdy Partner
</code></pre>
<p>You can also pipe the instructions in:</p>
<pre><code class="bash">cat create_instructions.yaml | yq n -s -
</code></pre>
<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>
<pre><code class="yaml">b:
foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
</code></pre>
<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
<pre><code class="bash">yq n -t -- --key --value
</code></pre>
<p>Will result in</p>
<p><code>`
--key: --value</code></p>

<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>

foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9

<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
<pre><code class="bash">yq n -t -- --key --value
</code></pre>
<p>Will result in</p>
<p><code>`
--key: --value</code></p>

<h1>Merge</h1>
<p>Yaml files can be merged using the 'merge' command. Each additional file merged with the first file will
set values for any key not existing already or where the key has no value.</p>

<p>Note that the 'b' array has concatenated the values from the second data file. Also note that other map keys are not overridden (field a).</p>
<p>Append cannot be used with overwrite, if both flags are given then append is ignored.</p>

<p>This command can take a json file as input too, and will output yaml unless specified to export as json (-j)</p>
<h3 id="basic">Basic<a class="headerlink" href="#basic" title="Permanent link">&para;</a></h3>
<p>Given a sample.yaml file of:</p>
<pre><code class="yaml">b:

<p>then</p>
<pre><code class="bash">yq r sample.yaml b.c
</code></pre>
<p>will output the value of '2'.</p>
<h3 id="from-stdin">From Stdin<a class="headerlink" href="#from-stdin" title="Permanent link">&para;</a></h3>
<p>Given a sample.yaml file of:</p>
<pre><code class="bash">cat sample.yaml | yq r - b.c

<h3 id="multiple-documents-specify-a-single-document">Multiple Documents - specify a single document<a class="headerlink" href="#multiple-documents-specify-a-single-document" title="Permanent link">&para;</a></h3>
<p>Given a sample.yaml file of:</p>

---
b:

</code></pre>
<p>then</p>
<pre><code class="bash">yq r -d1 sample.yaml b.c

<p>will output the value of '2'.</p>
<h3 id="multiple-documents-read-all-documents">Multiple Documents - read all documents<a class="headerlink" href="#multiple-documents-read-all-documents" title="Permanent link">&para;</a></h3>
<p>Reading all documents will return the result as an array. This can be converted to json using the '-j' flag if desired.</p>
<p>Given a sample.yaml file of:</p>
<pre><code class="yaml">name: Fred
age: 22
---
name: Stella
age: 23
---
name: Android
age: 232
</code></pre>
<p>then</p>
<pre><code class="bash">yq r -d'*' sample.yaml name
</code></pre>
<p>will output:</p>
<pre><code>- Fred
- Stella
- Android
</code></pre>
<h3 id="arrays">Arrays<a class="headerlink" href="#arrays" title="Permanent link">&para;</a></h3>
<p>You can give an index to access a specific element:
e.g.: given a sample file of</p>
<pre><code class="yaml">b:
e:
- name: fred
value: 3
- name: sam
value: 4
</code></pre>
<p>then</p>
<pre><code>yq r sample.yaml 'b.e[1].name'
</code></pre>
<p>will output 'sam'</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="array-splat">Array Splat<a class="headerlink" href="#array-splat" title="Permanent link">&para;</a></h3>
<p>e.g.: given a sample file of</p>
<pre><code class="yaml">b:
e:
- name: fred
value: 3
- name: sam
value: 4
</code></pre>
<p>then</p>
<pre><code>yq r sample.yaml 'b.e[*].name'
</code></pre>
<p>will output:</p>
<pre><code>- fred
- sam
</code></pre>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>
<pre><code class="yaml">b:
foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
</code></pre>
<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
<pre><code class="bash">yq n -t -- --key --value
</code></pre>
<p>Will result in</p>
<p><code>`
--key: --value</code></p>

<h1>Niche</h1>
<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>
<pre><code class="yaml">b:
foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
</code></pre>
<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
<pre><code class="bash">yq n -t -- --key --value
</code></pre>
<p>Will result in</p>
<pre><code>--key: --value
</code></pre>

<p>The flag terminator needs to be used to stop the app from attempting to parse the subsequent arguments as flags:</p>

<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>
<pre><code class="yaml">b:
foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
</code></pre>
<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
<pre><code class="bash">yq n -t -- --key --value
</code></pre>
<p>Will result in</p>
<p><code>`
--key: --value</code></p>
