Use latest stable

[Cecil Westerhof]

Is there a way to signify latest stable version? Because when you use:
  :dependencies [[org.clojure/clojure"LATEST"]
it wants to work with:
clojure-1.9.0-alpha10

I prefer to use clojure-1.8.0. There is a reason it is called alpha. But
when there is a stable 1.9.0 I want to use that one.

Notification about newer versions

[Cecil Westerhof]

In a project.clj I have:
  :dependencies [[org.clojure/clojure"1.8.0"]
 [clj-time   "0.8.0"]
 [com.h2database/h2  "1.3.176"]
 [instaparse "1.4.2"]
 [org.clojure/math.numeric-tower "0.0.4"]
 [seesaw "1.4.5"]
 [yesql  "0.4.0"]]

Is there a way to get notified about newer (stable) releases? They say:
never change a winning team, but I think it a good idea (most of the time)
to upgrade to a newer version when that is possible.

No - you'll have to specify "1.8.0" as the version if you want the
latest stable release. Maven-style repos support two special versions:
"LATEST" and "RELEASE". LATEST will give you the latest deployment,
either a release or a snapshot. RELEASE ignores snapshots, so you get
the latest release. Since there is no standard around qualifiers
(alpha, beta, final, experimental, etc) other than SNAPSHOT, the repo
has no way to know that 1.9.0-alpha10 has a different stability level
than 1.8.0.

However, I would recommend against using these special versions in
general (even if they did work the way you want), because you will at
some point get a new version with no action on your part. When this
happens, you may end up with test failures or new warning messages,
and have to track down the cause, looking at every dependency you have
set to a special version, with no immediate indication of which ones
may have changed.

​I have updated my project. I now use clj-time 0.12.0 instead of 0.8.0.
I partly updated yesql: from 0.4.0 to 0.4.2, but 0.5.0 and higher do not
work. I do not get an error, but it looks like queries are not executed or
give an empty result. I have to look into that.


It says you can check your profile also:
ancientCheck your projects and profiles for outdated
dependencies/plugins.

But that is not true: if I run it in a not project directory, I get:
(warn)  not inside of a project.

To check your profiles using lein-ancient, run:

lein ancient check-profiles

See the output of

lein help ancient

for  all available tasks.

​I should have looked a little further. It can be done with:

lein ancient check-profiles

I would expect that the profiles would be checked when not in a
project, but I can live with this.

lein repl and own functions

[Cecil Westerhof]

When I first worked with Clojure I used a Bash script with had:
rlwrap java -cp "${CP}" clojure.main --init "${CLOJURE_INIT}" --repl

In this way I had several of my own functions in the REPL. Now I started
again with Clojure I understood I should use ‘lein repl’. Is there a method
to get my own functions also included when using ‘lein repl’?

Re: Use latest stable

[Sean Corfield]

Toby gave you a good answer re “LATEST” and “RELEASE” but I’ll comment on 
stability of Clojure Alpha builds in general:

 

We first went to production with Clojure in 2011 on 1.3.0 Alpha 7 (or 8, I no 
longer remember which). We’re currently in production with 1.9.0 Alpha 10. 
Prerelease builds of Clojure have been remarkably stable and this allows us to 
leverage new functionality as soon as it becomes available.

 

In particular, 1.9.0 Alpha 10 is just 1.8.0 + a handful of new predicates in 
core + clojure.spec.

 

The new predicates may cause warnings or errors if you’re using libraries that 
define their own versions but we have already adopted several of them so we 
could simplify our existing code and remove some of our own custom predicates.

 

Otherwise it’s a purely additive release and you can simply ignore clojure.spec 
if you’re not ready to use it (we’re already developing new production code on 
top of it, although that hasn’t been merged to our production branch yet).

 

We have had automated testing against Clojure’s master SNAPSHOT for years so we 
always get an early heads up if an upcoming “RELEASE” change would break 
anything. That’s easy to do with Leiningen profiles or Boot pods (and tasks 
like boot-expectations allow you to specify which version of Clojure to use, so 
multi-version testing is pretty much trivial!).

Re: Use latest stable

[Alan Thompson]

If you haven't seen it yet, lein-ancient (
https://github.com/xsc/lein-ancient) provides an easy way of checking your
project for out of date dependencies.  For example:

> lein ancient
[criterium "0.4.4"] is available but we use "0.4.3"
[tupelo "0.9.0"] is available but we use "0.1.60"
[com.rpl/specter "0.11.2"] is available but we use "0.9.1"


I tend to run it every couple of months, or whenever I remember.  Then it
is easy to update project.clj

​Well, I could put in my profiles.clj LATEST and in all my project.clj
1.8.0​

Re: lein repl and own functions

[Timothy Baldridge]

There probably is, since the user.clj file can exist anywhere on the
classpath. So it should be possible to add an entry to profile.clj and add
a classpath folder to some global location.

However, I'm not sure I would recommend this approach. IMO, it's better to
keep all the development tools for a project with the project itself. With
a local user.clj you can check that into git and have it the next time you
share/re-download the project.

​Yes, in another tread I was pointed to that. Very handy indeed. I could
write a script that I run every week in crontab that would notify me when
something is to old.

Have to take care of a few things:
- Latest of H2 is 1.4.192, but latest stable is 1.3.176.
- Latest of yesql is 0.5.3 ​, but my application does not work with a
version after 0.4.2.

Re: lein repl and own functions

[Gary Trakhman]

One way to abuse lein repl, which may get you what you want for a loose
'lein repl' but is sure to cause some problem down the line is to add a
project.clj in your home directory. When you call `lein repl` it'll recurse
from current working directory through parent dirs until it finds a
project.clj, which will be your root project unless you're in another
clojure project.  I have found this to sometimes lead to surprising
behavior, and no longer do it.

Running a certain function of your project

[Cecil Westerhof]

In my project I have some functions I use when calling ‘lein repl’ in the
project directory. Would it be possible to use just that function? So use
lein to call this function and return?

Maybe not very useful because of the time it takes to start the JVM, but I
like to experiment. ;-)

Re: Running a certain function of your project

[Thomas Mulvaney]

For one-off scripts I typically have a `scripts/` directory in my projects.
I also have a scripts profile in my project.clj which includes "src/clj"
and "scripts", that way my scripts can call functions from my project. I
then have a bash script called `bin/script` which just contains "lein run
with-profile +scripts -m $@"

Now, say I have a script with namespace 'db.migrate' under
"scripts/db/migrate.clj", calling it is just a matter of doing `bin/scripts
db.migrate arg1 arg2 `.

Re: Error when upgrading yesql from 0.4.2 to 0.5.0

[Sean Corfield]

The yesql.named-parameters namespace was removed between 0.4.2 and 0.5.0.

 

You can see all the changes made between 0.4.2 and 0.5.0 here:

 

https://github.com/krisajenkins/yesql/compare/v0.4.2...0.5.0

 

It looks like 0.5.0 was a pretty major rewrite with a lot of API changes.

Google has the Migration Guide cached, if that helps:

And, yes, a LOT of API changes…

Re: [ANN] Nightcode 2: Total Rewrite

[Yoko Harada]

Thanks for the update! A single REPL window on the new version looks nice.
It's good to avoid confusion for beginners.
Recently, ClojureBridge (clojurebridge.org) officially switched to
Nightcode. I think ClojureBridge students will like this easy to use editor.

However, there's a really *ouch* problem in version 2.0.0. It doesn't play
nicely with Overtone. ClojureBridge has one Overtone material, which works
well on night code 1.3.1. I could run (piano),  (piano 48) or other
Overtone functions many times on the REPL window. But, on 2.0.0, if I run
(piano) once, that's it. REPL window acts weirdly.

Are there any links to older versions? For a while, ClojureBridge wants to
stick to version 1.3.x.

Re: [ANN] Nightcode 2: Total Rewrite

[Boris Kourtoukov]

Hi Yoko,

If all you need is standalone jar versions of Nightcode you can see all the 
past releases here: https://github.com/oakes/Nightcode/releases 

The jar should run on any platform. 

Best,
Boris

Re: ANN: diehard 0.1.0, a Clojure wrapper for Failsafe

[Ning Sun]

Quick update: diehard 0.2.2 released with circuit breaker support.

;; Define a circuit breaker with failure threshold:
;; it will be open when 35 executions in 50 failed
;; and it waits 1000ms to become half-open, and tests 50 executions to
;; see if failure is recovered

(diehard/defcircuitbreaker test-cb {:failure-threshold-ratio [35 50]
:delay-ms 1000})

;; you code within `with-circuit-breaker` will be protected by this
;; circuit breaker `test-cb`
;; if it's open, the block will throw a
;; `net.jodah.failsafe.CircuitBreakerOpenException`
;; and fail fast without blocking.

(diehard/with-circuit-breaker test-cb
  ;; your protected code here
  )
