Is there any way to filter githubLatestTag?

[xfzv]

I'm having the following in my .chezmoiexternal.yml:

".local/bin/notesnook.AppImage":
  type: "file"
  executable: true
  url: "https://github.com/streetwriters/notesnook/releases/download/{{ (gitHubLatestRelease "streetwriters/notesnook").TagName }}/notesnook_linux_x86_64.AppImage"
  refreshPeriod: "168h"

It works fine for the most part, but fails sometimes. Indeed, this repository (streetwriters/notesnook) is a bit special since it provides both desktop and Android variants of the app mixed in the releases section.

As a result, if the latest tag is for an Android version like right now:

chezmoi apply will fail as expected with the following error:

❯ chezmoi apply
chezmoi: .local/bin/notesnook.AppImage: https://github.com/streetwriters/notesnook/releases/download/2.6.1-android/notesnook_linux_x86_64.AppImage: 404 Not Found

Is there a way to filter the template in order to use the latest tag that doesn't contain -android for example?

With:

url: "https://github.com/streetwriters/notesnook/releases/download/{{ (gitHubLatestRelease "streetwriters/notesnook").TagName | replaceAllRegex "-android" "" }}/notesnook_linux_x86_64.AppImage"

I can get chezmoi to fetch https://github.com/streetwriters/notesnook/releases/download/2.6.1/notesnook_linux_x86_64.AppImage so -android is removed from the URL correctly, but of course it still fails because there's no 2.6.1 for desktop.

Any idea is appreciated.

No, and I’m not sure that there would be an easy way to add one in since there’s no real "lambda" support in Go’s text/template.

You could get something similar with a combination of the output, fromJson, and jq functions with the gh command (you could use curl, too):

chezmoi execute-template '{{ (output "gh" "api" "repos/streetwriters/notesnook/releases" | fromJson | jq "map(select(.tag_name | endswith(\"-android\") | not))[0] | .assets | map(select(.name | contains(\"AppImage\")) | select(.name | contains(\"x86_64\")))" | first | first).browser_download_url }}'

There is no caching with this option, though.

It shouldn’t be hard to add githubTags or githubReleases functions that does cache the result and returns the last 30 of each so that you could then build jq filtering of your own.

Thank you @2-4601 @bradenhilton, both variants work fine indeed.

It shouldn’t be hard to add githubTags or githubReleases functions that does cache the result and returns the last 30 of each so that you could then build jq filtering of your own.

What would be the benefits of this? circumventing the API rate limit?

[halostatue]

It doesn’t circumvent it in the case of multiple runs, but given that "output" doesn’t cache at all, every time that segment gets executed in a template, it would use an API request.

githubTags and githubReleases functions would also automatically take advantage of the GitHub token environment variables.

Exploring this option in #3164.

So now that a513d19 is there (thank you @halostatue), I guess I should use githubReleases.

  url: "{{ (gitHubReleases "streetwriters/notesnook" | toJson | fromJson | jq "map(select(.tag_name | endswith(\"-android\") | not))[0] | .assets | map(select(.name | contains(\"AppImage\")) | select(.name | contains(\"x86_64\")))" | first | first).browser_download_url }}"

Is this right? It works fine on my end, but I wonder if some adjustments should be done.

[halostatue]

No, that looks about right. It's really complicated, but it gives you exactly what you need.
