Same info would be shown when doing :recipe/info on REPL.

Currently you need to append /raw to a gist-url to successfully load it as recipe.

Doesn't work:

$ deps-try --recipe https://gist.github.com/eval/ee80ebddaa120a7732396cea8cfc96da

Does work:

$ deps-try --recipe https://gist.github.com/eval/ee80ebddaa120a7732396cea8cfc96da/raw

The former should be supported as well.

The full home directory is "C:\Users\Tobias Dummschat", but it tries finding the file "C:\Users\Tobias".

Like https://martinheinz.dev/blog/94

No better way to start a REPL-session than a good quote.

Almost all new ideas
have a certain aspect of foolishness
when they are first produced

$ deps-try recipes:create --ns recipes.clojure.intro 
(ns recipes.clojure.intro
  "Title here"
  {:deps-try.recipe/deps ["replace/me" "0.1.2"]})

;; step 1
(+ 1 2)


;; step 2
(/ 6 3)

Should be easy to create recipes based on last X steps in REPL-history:

# right after closed REPL-session
$ deps-try recipes:create --ns recipes.clojure.intro --include-history 10 

naming: include-history, history-items, last-history-items...

Not sure about the recipe name, but aiming for something like:

$ deps-try --recipe gist.github.com/some/gist

This seeds the history with the commands in the gist.
Behavior:

• history (arrow up progresses down this list):
  • gist command 1
  • gist command 2
  • etc
  • latest command user's history
  • etc
• run command:
  • put it in user's history
  • 'gist command 2' now top of history
• commands are labeled in order to easily find them (for this session or when stored in user's history). Also needed to see what commands from recipe were run:

;; recipe.name/1
;; Introduction to malli...
;; Let's get the libraries needed for this recipe:
:deps/try metosin/malli

;; recipe.name/2
;; Let's require the namespaces we need:
(require '[malli.core :as m])

All of the affordances of deps-try would be very welcome when I am using the shadow-cljs cljs-repl, for example.

(require '[clojure.set :as cset])
(clojure.set| ;; ^X^D works
(cset| ;; doesn't work

Will come in handy:

(compliment.utils/resolve-namespace 'cset *ns*)

Thank you for your work Gert! :)

Found a small issue with a specific repo that I wanted to try. I wanted to try Squint and I found a weird interaction with the babashka/fs dependency. A work around is to add the dep manually (deps-try babashka/fs io.github.squint-cljs/squint). I don't see yet what the cause is though. A shell session below.

(FYI, I installed deps-try via bbin install io.github.eval/deps-try, works fine, after finding the error I also tried the other ways, but that was not it).

Shell session:

➜ bb version
babashka v1.3.184

➜ deps-try -v
deps-try-dev v0.8.0

➜ deps-try io.github.squint-cljs/squint

I tried deps-try amazonica "0.3.165" which results in an error Could not find path '***/amazonica'

I should have tried deps-try amazonica/amazonica "0.3.165" instead, and then things work as expected.

This might not be obvious for new users. I also had to think for a bit. And this would also not be obvious by reading the README of Amazonica where it is still [amazonica "0.3.165"].

When there is no namespace maybe if the directory doesn't exist (in this case amazonica), deps-try could try to resolve it as a dependency?

(*) tested with version deps-try-dev v0.8.0

Currently deps.edn is ignored in order to make sessions as deterministic as possible.
It has value though to 'try' project-code.

directions

• using :local/root (version possible?)
  pointing elsewhere: deps-try ../project
  at PWD: deps-try .
• the latter case could be supported by a config setting as well: take ./deps.edn into account when present

Both GitHub and GitLab support special refs for PR/MR's. Resp. refs/pull/123/head (and refs/pull/123/merge) and refs/merge-requests/123/head (and refs/merge-requests/123/merge). All of these refs currently work. But it would be nice to make these first-class-versions, e.g.:

$ deps-try com.github.metosin/malli pr/123 mr/123

It might feel safer for some users to always execute code (especially with recipes) in a sandbox.

$ docker run -it eval/deps-try metosin/malli

Currently com.github.user/project is treated as a git/url, but it's also a format used for artifacts.
Failing examples:
com.github.kyleburton/clj-xpath (it exists on github but is not using tools-deps).

Currently just a println.

Feedback from /r/clojure:

it'd be lovely to have a ready-to-use binary release instead of having to install bbin from a Homebrew (because that would be like third package manager I have on my Linux, which is two more than a reasonable amount).

user=> :deps/try https://github.com/metosin/malli
user=> ^D
# hangs a minute before terminating

Seems due to threads that are still active. A simple (future (prn 1)) has the same issue.

Example:

# this shows clojure.data.csv as option
$ deps-try org.clojure/data.csv
user=> (require '[clojure.data.<TAB>

# this doesn't
$ deps-try
user=> :deps/try "org.clojure/data.csv"
user=> (require '[clojure.data.<TAB>

See https://github.com/alexander-yakushev/compliment/blob/master/src/compliment/utils.clj

The completer currently shows namespace suggestions based on files found on classpath, e.g. clojure.data.x becomes clojure.data.xml. Though adding a slash then and hitting TAB to dig deeper will however do nothing as clojure.data.xml is not required and so no var can be suggested.

A shortcut for require-at-point would allow for quick exploration of the namespace at hand.

Downside would be that the code that you end up with in e.g. the history is less useful: the user depended on separate actions to make the code work.

Following should be accepted:
$ deps-try -d/--debug

Together with a logical (announced?) place to store the file.

https://github.com/babashka/babashka/wiki/Self-contained-executable#uberjar

$ deps-try -v/--version

directions

• have version built-in
  cons:

  • double administration with tags

  pro:

  • easiest

• trigger CI and bake version in
  cons:

  • more involved as CI needs to create a tagged commit
