This is the best introduction to #Bazel that I have found. This ~30 minute talk covers writing your own macros and rules, using LaTeX compilation as an example. Maybe Bazel is deemed difficult enough as it is, but many resources, even books on Bazel, do not cover this. https://media.ccc.de/v/froscon2017-1946-bazel
I’m currently trying to package several of our static library into dynamic framework using ios_framework rule in #Bazel but there’s an intermittent failure on bundling steps.
It says I copied the same framework twice.
@thePunderWoman That's a #Bazel thing, and not really a common term. I think many Nooglers get just as confused regardless of background.
Even the internal Bazel docs concede that it's a misnomer. It's just called that to algin with `go_binary`, `java_binary`, etc.
Set up a project with #Bazel for building #Android #apps📱 By @Neurenor
I'm kind of impressed that every single tool or plugin meant to work with #bazel is AT MOST half-baked.
wish the #bazel rules_python upstream would notice my PR one way or another but hey. corporate OSS project not the community projects I'm used to. either way about to get shmoovin
One of the things I learned that I didn’t know while developing this feature: #Bazel. First and foremost, I don’t have a good mental model of how it works, especially when it comes to looking up compilers and setting options for compilers. #FormaK benefits by being able to easily zip together Python, C++ and generated C++ in Bazel, but working on improving the C++ integration feels like stumbling in the dark hoping I find a light switch
So here's my #bazel review. Good theoretical model. When it works it may as well be alien technology. But it's horrendously underdocumented and obviously not designed for consumption by people who haven't already learned on Blaze. And the OSS rules are pretty low quality. And half the stuff you need to make it work - cache management, bad action purging, analysis cache persistence, ... happens to not be OSS.
Trying a #bazel gazelle inventory run as poc on the #aws #go sdk github.com/aws/aws-sdk-go-v2 as part of a try to perform a bazel build for the #crossplane aws provider.
a time consuming run ...
Finally getting to hello world after installing mediapipe on Windows seems like an achievement!
MSYS2, pacman, python, Visual Studio (2019!), Visual C++ Build tools (from VS2019, not 2022), Windows SDK, chocolatey, Bazel(isk), git clone, opencv unzipping installer, and a few env vars.
Well documented here, but still 😅https://developers.google.com/mediapipe/framework/getting_started/install#installing_on_windows

I started writing a toot-storm, but I realized a blog post was a better medium for it. Enjoy: https://www.buildbuddy.io/blog/multiple-xcode-configurations-with-rules_xcodeproj-1-3
Is it currently not possible to implement on-demand resources in #Bazel? Have been searching on internet as well as in rules_apple and swift but found little information about this.
Shout out to `bazel query --output graph` and https://dreampuf.github.io/ for visualizing it. Debugged some tricky dependency graphs today and I'm not sure I could have done it without those tools.
in the first draft I couldn't figure out how to cross build using MODULE.bazel, but eventually I figured it out, so I updated the post yesterday. also made a PR to show that it actually works on GitHub Actions.
wrote a blog post 'cross build anything with Bazel'
this technique is not limited to JVM, I figured #Scala cross building is a representative example, so I used it as an example on how it can be done using the local_repository technique
Me: Hey #Bazel, what depends on "golang.org/x/net" in my repo?
I will use this image in a future slide. And it's only 1/8 of the actual SVG file 😤
it happens so that in different orgs that I work for, the first things I tackle is the library dependency issue.
this week @ianoc showed me a neat trick of using --override_repository to switch out a local repository in #Bazel. I've heard this technique described in the past but didn't realize how powerful it was atm.

After a lot of work, I've finally landed a release of #Bazel #rules_prerender which is compatible with #aspect_rules_js! https://github.com/dgp1130/rules_prerender/releases/tag/releases%2F0.0.17
This has been a long time coming, and the issue shows how big a change this was (https://github.com/dgp1130/rules_prerender/issues/48). It didn't help that I kept getting distracted with other things and forgot everything I was doing. 😅
#aspect_rules_js does seem like a solid improvement and it sets up #rules_prerender for a lot of awesome improvements in the future (#ESM, #bzlmod, better bundling, etc.) Super excited about where we can take this next!
Shout out to @alexeagle and Greg Magolan (who I don't think is on Mastodon?) for their help, couldn't have done it without you!
@rheber Strictly speaking you don't, I get that. But I want one because:
1. The commit which adds an empty `package.json` should also add a lockfile for symmetry, to make sure it isn't forgotten later, and to keep everything to a single commit.
2. Some tools expect or require a lockfile to function. In this case, #Bazel is very strict that a lockfile must exist to do anything, even if it's empty.
Apparently the production #Bazel docs use the nightly build. I found `native.package_relative_label()` in the docs and was trying to use it but consistently failing. I tried to trace down when the function was added, and discovered it was merged _yesterday_. How's that for turnaround time?
I made a small quality-of-life improvement to #Bazel's Objective-C/C++ compile action sets back in 2021 while working on Pinterest's iOS build system.
It took a while to be reviewed, but I'm happy to see that it was just merged.
I’m so excited to announce we’ve released version 1.0 of #rules_xcodeproj!
For a release this important, I’ve written a blog post. Please enjoy 😊.
@techytacos Don't get me wrong, #ISR is great. #Bazel is great. ISR + Bazel? More conflicts than sodium and water.
#Terrible #Idea: An incremental static rendering (#ISR) solution which calls #Bazel build in production to generate #HTML, #JS, and #CSS files which get served directly to users.
This is objectively one of the dumbest and worst ideas I've ever come up with, so I made a feature request for it over-analyzing the idea way too much.
I would be very curious to know exactly _which_ aspect of the idea breaks first. Is it memory limitations? Cache invalidation? Database management? Backend usage? #RBE SLOs? So many things things that could ruin it!
I’m currently doing some profiling work with #Bazel to see if extracting some modules would speed up overall build time.
After gathering the data from build profile, this modules takes 50s on average to compile with 40s for its fastest time and 61s for the slowest time. With n=10, I got 12.7 for 2STDev which means I don’t need to remove all the data point.
I think I should’ve make it run 20 times.
Been doing this modularization and profiling work in #Bazel since end of last year.
I guess a lot of time is spent on waiting build to success. 😂
Since the hashtag is totally empty for me on here, I'll start it:
Anyone on the #fediverse want to talk to #turborepo, let me know :D.
#vercel #monorepo #nextjs #frontend #programming #nx #moon #bazel #etc #etc
Just wasted an hour debugging why:
name = "tsconfig",
src = "tsconfig.json",
Wasn't working as expected.
Apparently #Bazel #Starlark is just ok with loading the same symbol from two different locations and has no complaints! 🙃
I happy to announce that I’ve just released version 0.12 of #rules_xcodeproj!
Like the release before it, I didn’t plan to have another release before the 1.0 release candidates, but since a fair amount of improvements and bug fixes made it in, I felt it wasn’t worth waiting to get these changes out.
Please read the release notes (https://github.com/buildbuddy-io/rules_xcodeproj/releases/tag/0.12.0) for a detailed account of what is included in this release.
Google casually mentioned that they use a custom hash algorithm for their internal build tool #bazel is mind-blowing.
I barely know what AVX2 is. Git is still having a really hard time getting off SHA1 into SHA256. And these guys said "oh we have been passed all that since 2018"... 🤣
Bazel has a good chance at being a good build system, once it gets past its growing pains.
Growing pains: shifting conventions on how to get stuff done; dense and circuitous documentation.
@lobsters seems like #bazel caching would have also solved that @GabriellaG439
#Bazel 6.0 was just released!
I spent some time (okay, a lot of time) reviewing all of the commits since Bazel 5.4, and wrote up a blog post summarizing the ones I found interesting: https://brentley.dev/whats-new-in-bazel-6.0/
@rain These might help giving some context from #bazel side
I am not familiar with Godel's theorem though.
Do Skylark/Starlark as present in #bazel etc describe exactly the set of "primitive recursive functions" as seen in Gödel's incompleteness theorem?
LOOKS LIKE BUILDFILES ARE BACK ON THE MENU BOYS #bazel
Google Cloud and Firestore vs Datastore (3/n): the documentation for getting started refers to a Maven dependency that is no longer hosted in the registry (doc refers to firebase-admin 1.32.0, most recent version seems to be 9.1.1). Not a deal for people who know what they are doing, but not an example of a smooth experience.
Wondering what this means for #Bazel though where we experience similar feedback about documentation 🙈
Hi, I am Eugene, a programmer working around #fp, #Scala, and tooling like #sbt and #Bazel, most recently I was at Twitter's Build team
I enjoy exploring complex landscape, and tweaking them to make things better for other programmers #introduction https://eed3si9n.com/about/
Exploring Fediverse from a different place, here's my local #introduction
Working as Eng Manager at #Google in #Munich on #Bazel which became my happy place after different projects and roles. I enjoy working as #facilitator, #mentor and #respect advisor in my org.
I've been exploring Mastodon from a private instance so far, and already learned that discovering content and people is a whole different thing on a well established instance. Let's try!
Thank you @nova (or, .io?) for hosting!
Time for my #introduction!
I’m Brentley (he/she/they) and I’m a Developer Evangelist at @buildbuddy. I focus on #iOS / #Mobile and #Bazel. I’m also the creator of #rules_xcodeproj, a Bazel-integrated #Xcode project generator.
I’m a big user/fan of #SwiftLang, but I would love to someday be able to learn and use #Elixir or #Lisp for something in production 😄.
On the non-tech side, I love #movies, #tv, and #TTRPG. I’ll sometimes dabble in #videogames (mainly #pokemon).
Imagine if you could:
- open VS Code
- write some #Rust
- install and setup #Bazel
- compile to #WASM
- create a serverless #Nodejs function
- deploy to the Cloud
