## Requirements
Some of those scripts have external requirements. You can install them with the following commands:
```
python3 -m pip install -r requirements.txt
```
## find_pr.py
```
$ ./find_pr.py --help
Usage: find_pr.py [OPTIONS] PATH
Find what GitHub pull requests touch a given file.
ex: ./find_pr.py --tags "language/fr" "content/fr/_index.html"
Options:
--tags TEXT Tags of PullRequest (Can be passed multiple times)
--token TEXT GitHub API token. (Default env variable GITHUB_TOKEN)
--last-n-pr INTEGER Last n-th PullRequests
--help Show this message and exit.
```
## upstream_changes.py
```
$ ./upstream_changes.py --help
Usage: upstream_changes.py [OPTIONS] PATH
Find what changes occurred between two versions
ex: ./upstream_changes.py content/fr/_index.html
Options:
--reference TEXT Specify the reference version of the file. Default to the
English one.
--git-path TEXT Specify git path
--help Show this message and exit.
```
## test_examples.sh
This script tests whether a change affects example files bundled in the website.
To install the dependencies:
$ ./scripts/test_examples.sh install
To run the examples:
$ ./scripts/test_examples.sh run
## check-headers-file.sh
This script checks the headers if you are in a production environment.
./scripts/check-headers-file.sh
## diff_l10n_branches.py
```
$ scripts/diff_l10n_branches.py --help
Usage: diff_l10n_branches.py [OPTIONS] L10N_LANG L_COMMIT R_COMMIT
This script generates a report of outdated contents in `content/<l10n-
lang>` directory by comparing two l10n team milestone branches.
L10n team owners can open a GitHub issue with the report generated by this
script when they start a new team milestone.
ex: `scripts/diff_l10n_branches.py ko dev-1.15-ko.3 dev-1.15-ko.4`
Options:
--src-lang TEXT Source language
--help Show this message and exit.
```
## hash-files.sh
This script emits as hash for the files listed in $@.
$ ./scripts/hash-files.sh
## linkchecker.py
This a link checker for Kubernetes documentation website.
- We cover the following cases for the language you provide via `-l`, which
defaults to 'en'.
- If the language specified is not English (`en`), we check if you are
actually using the localized links. For example, if you specify `zh` as
the language, and for link target `/docs/foo/bar`, we check if the English
version exists AND if the Chinese version exists as well. A checking record
is produced if the link can use the localized version.
```
Usage: linkchecker.py -h
Cases handled:
- [foo](#bar) : ignored currently
+ [foo](http://bar) : insecure links to external site
+ [foo](https://k8s.io/website/...) : hardcoded site domain name
+ [foo](/<lang>/docs/bar/...) : where <lang> is not 'en'
+ /<lang>/docs/bar : contains shortcode, so ignore, or
+ /<lang>/docs/bar : is a image link (ignore currently), or
+ /<lang>/docs/bar : points to shared (non-localized) page, or
+ /<lang>/docs/bar.md : exists for current lang, or
+ /<lang>/docs/bar/_index.md : exists for current lang, or
+ /<lang>/docs/bar/ : is a redirect entry, or
+ /<lang>/docs/bar : is something we don't understand, then ERR
+ [foo](/docs/bar/...)
+ /docs/bar : contains shortcode, so ignore, or
+ /docs/bar : is a image link (ignore currently), or
+ /docs/bar : points to a shared (non-localized) page, or
+ /docs/bar.md : exists for current lang, or
+ /docs/bar/_index.md : exists for current lang, or
+ /docs/bar : is a redirect entry, or
+ /docs/bar : is something we don't understand
+ [foo](<lang>/docs/bar/...) : leading slash missing for absolute path
+ [foo](docs/bar/...) : leading slash missing for absolute path
```
## lsync.sh
This script checks if the English version of some localized contents have changed
since a localized version has been committed.
The following example checks a single file:
./scripts/lsync.sh content/zh-cn/docs/concepts/_index.md
The following command checks a subdirectory:
./scripts/lsync.sh content/zh-cn/docs/concepts/
## check-ctrlcode.py
This script finds control-code(0x00-0x1f) in text files.
It will display illegal character in browser.
```
Usage: ./check-ctrlcode.py <dir> <ext>
<dir> Specify the directory to check.
<ext> Specify the extension to check.
For example, we can execute as following.
./check-ctrlcode.py ../content/en/ .md
The output is following format.
"{0} <L{1}:{2}:{3}>: {4}"
{0} : The path of file that a control-code exists.
{1} : The line number that a control-code exists.
{2} : The column number that a control-code exists.
{3} : The found control-code.
{4} : The one-line strings in the file.
```
## ja/verify-spelling.sh
This script finds Japanese words that are against the guideline[1]
[1] https://kubernetes.io/ja/docs/contribute/localization/#%E9%A0%BB%E5%87%BA%E5%8D%98%E8%AA%9E
```
Usage: ./ja/verify-spelling.sh
