Hello! How can I lint all files in dir?
rende11 2019-01-04T16:21:06.005400Z
Like
joker --lint ./srcrende11 2019-01-05T09:50:52.006700Z
But I have another problem - I receive some warnings but exit code is 0
rende11 2019-01-05T10:00:37.006900Z
I try to parse output
OUTPUT=`$(find ./src -type f -exec joker --lint {} \;)` rvm:ruby-2.5.3
./src/server/core.clj:17:13: Parse warning: arg[1] of core/+ must have type Number, got String
./src/server/core.clj:3:14: Parse warning: unused namespace bidi.bidirende11 2019-01-05T10:00:59.007100Z
but it's empty
echo $OUTPUT

OUTPUT=$(...) captures stdout, but not stderr, unless you put a 2>&1 in there near the end, to redirect stderr to stdout.
jcburley 2019-01-05T15:18:03.007500Z
As far as the exit code, maybe there's some trick to doing it via find -exec, but that might require something more sophisticated, like this:
$ FILES=$(find . -type f)
$ RC=0; while read P; do joker --lint $P >/dev/null 2>&1 || RC=1; done <<< "$FILES"
$ echo $RC
1
$

Thx! Now I use
if [ $(find ./src -type f -exec joker --lint {} \; 2>&1 | wc -l) -ne 0] ....jcburley 2019-01-05T17:08:30.008Z
That seems reasonable, since joker --lint should produce no output (stdout nor stderr) if there are no issues with the code.
jcburley 2019-01-04T16:25:18.005500Z
I don't think Joker supports linting multiple files in one invocation, so perhaps this something like this might be sufficient?:
$ find ./src -type f -name "*.cljc" -exec joker --lint \{} \;
rende11 2019-01-04T19:49:51.005700Z
Error: Cannot provide arguments to code while linting it.
seancorfield 2019-01-04T20:42:47.005900Z
There shouldn't be a \ before {}
jcburley 2019-01-04T22:41:01.006100Z
Works for me (in Bash):
$ find ./src -type f -name "*.clj" -exec joker --lint \{} \;

(That's in the Clojure source directory -- some of the files actually crash Joker!)
