Changelog

master (unreleased)

0.6.0 (2019-02-05)

New features

  • #117: Replace nrepl.middleware.pr-values with nrepl.middleware.print.
    • New dynamic vars in nrepl.middleware.print for configuring the print middleware at the REPL.
    • The new middleware provides behaviour that is backwards-compatible with the old one. Existing middleware descriptors whose :requires set contains #'pr-values should instead use #'wrap-print.
  • #128: New middleware, nrepl.middleware.caught, provides a hook called when eval, read, or print throws an exception or error. Defaults to clojure.main/repl-caught. Configurable by the dynamic var nrepl.middleware.caught/*caught-fn*.

Bugs fixed

  • [CLI] Make sure ack port parameter is converted to integer for command line nREPL initialization.
  • [CLI] When starting the REPL, make sure the transport option is used correctly.
  • [CLI] Make sure calling send-ack at cmdline ns works with the correct transport.
  • #8: Clean up context classloader after eval.

Changes

  • #16: Use a single session thread per evaluation.
  • #107: Stop reading and evaluating code on first read error.
  • #108: Refactor cmdline functions into a public, reusable API.
  • Restore the nrepl.bencode namespace.

0.5.3 (2018-12-12)

Bugs fixed

  • Make sure we never send a nil transport to via send-ack.

0.5.2 (2018-12-10)

Bugs fixed

  • [CLI] #90: Doesn't display properly URLs if using a 3rd-party transport.

0.5.1 (2018-11-30)

Changes

  • #89: Remove tools.logging dependency.

0.5.0 (2018-11-28)

New features

  • #12: Support custom printing function in pr-values, enabling pretty-printed REPL results.
  • #66: Add support for a global and local configuration file.
  • [CLI] #63: Make it possible to specify the transport via the command-line client (--transport/-t).

Bugs fixed

  • #10: Bind *1, *2, *3 and *e in cloned session.
  • #33: Add ability to change value of *print-namespace-maps*.
  • #68: Avoid illegal access warning on JDK 9+ caused by nrepl.middleware.interruptible-eval/set-line!.
  • [CLI] #77: Exit cleanly after pressing ctrl-d in an interactive REPL.
  • #13: Catch ThreadDeath exception thrown by interrupt.

Changes

  • #56: Bind the server by default to 127.0.0.1 instead of to :: (this turned out to be a security risk).
  • #76: Move version-related logic to a dedicated namespace (nrepl.version).
  • Deprecate nrepl.core/version.
  • Deprecate nrepl.core/version-string.
  • [CLI] #81: Handle interrupt in interactive session.

0.4.5 (2018-09-02)

New features

  • [CLI] The built-in the CLI generates an .nrepl-port file on server startup.
  • [CLI] #39: Add a --connect command-line option allowing you to connect. with the built-in client to an already running nREPL server.
  • [CLI] Add shorthand names for most command-line options.
  • [CLI] Add a -v/--version command-line option.

Changes

Bugs fixed

  • #38: Remove extra newline in REPL output.

0.4.4 (2018-07-31)

New features

  • [CLI] Added --help command-line option.
  • [CLI] Added --bind command-line option.
  • [CLI] Added --handler and --middleware command-line options. Extremely useful when starting nREPL using clj and tools.deps, as this allows you to inject middleware trivially without the need for something like lein or boot.

Bugs fixed

  • [CLI] Add missing newline after colorized values displayed in the REPL.

0.4.3 (2018-07-26)

New features

  • [CLI] Display connection info when starting the built-in cmd client. This makes it possible for clients like CIDER to parse it and auto-connect to the server. Pretty handy if you're using clj to start your server.

Bugs fixed

  • #16: Don't change the thread used for form evaluation over time. See #36 for a discussion of the fix. (partial fix)

Changes

  • The result of nrepl.server/start-server no longer contains the legacy key :ss from the days of nREPL 0.0.x. If someone was using it they should switch to :server-socket instead.
  • #28: Echo back missing ns during eval (previously you'd only get an error that a ns is missing, but no mention of the name of that namespace).

0.4.2 (2018-07-18)

Changes

  • #35: Add constant DCL across evaluations (which means you can now easily hot-load dependencies).

Bugs fixed

  • #34: Treat nil port as 0 (which assigns a random port).

0.4.1 (2018-05-23)

Bugs fixed

  • #11: Don't read the version string from a resource file (version.txt).

0.4.0 (2018-05-21)

Changes

  • #4: Change the project's namespaces. (breaking) clojure.tools.nrepl is now nrepl.core, the rest of the namespaces were renamed following the pattern clojure.tools.nrepl.* -> nrepl.*.

0.3.1 (2018-05-19)

Bugs fixed

  • #15 Fix for clojure.tools.nrepl.middleware.session for :unknown-session error and clojure.tools.nrepl.middleware.interruptible-eval for :no-code error, the correct response of :status :done is now being returned.
  • #26: Recompile the Java classes for Java 8.

0.3.0 (2018-05-18)

Changes

  • #1: Materially identical to [org.clojure/tools.nrepl "0.2.13"], but released under nrepl/nrepl coordinates as part of the migration out of clojure-contrib https://github.com/nrepl/nrepl
  • clojure.tools/logging is now a normal dependency (it used to be an optional dependency).

Bugs fixed

  • #20: If start-server is not provided with a :bind hostname, nREPL will default to binding to the ipv6 :: (as before), but will now always fall back to localhost. Previously, the ipv4 hostname was only used if :: could not be resolved; this change ensures that the localhost fallback is used in networking environments where :: is resolved successfully, but cannot be bound.

0.2.13:

  • start-server now binds to :: by default, and falls back to localhost, avoiding confusion when working in environments that have both IPv4 and IPv6 networking available. (NREPL-83)

0.2.11:

  • clojure.tools.nrepl.middleware.interruptible-eval now accepts optional file, line, and column values in order to fix location metadata to defined vars and functions, for more useful stack traces, navigation, etc.
  • REPL evaluations now support use of reader conditionals (loading .cljc files containing reader conditionals has always worked transparently)

0.2.10:

  • clojure.tools.nrepl.middleware.pr-values will not print the contents of :value response messages if the message contains a :printed-value slot.
  • default-executor and queue-eval in clojure.tools.nrepl.middleware.interruptible-eval are now public.

0.2.9:

  • clojure.tools.nrepl.middleware.interruptible-eval now defines a default thread executor used for all evaluations (unless a different executor is provided to the configuration of clojure.tools.nrepl.middleware.interruptible-eval/interruptible-eval). This should aid in the development of interrupt-capable alternative evaluation middlewares/handlers.

0.2.8:

  • The default bind address used by clojure.tools.nrepl.server/start-server is now localhost, not 0.0.0.0. As always, the bind address can be set explicitly via a :bind keyword argument to that function. This is considered a security bugfix, though technically it may cause breakage if anyone was implicitly relying upon nREPL's socket server to listen on all network interfaces.
  • The ServerSocket created as part of clojure.tools.nrepl.server/start-server is now configured with SO_REUSEADDR enabled; this should prevent spurious "address already in use" when quickly bouncing apps that open an nREPL server on a fixed port, etc. (NREPL-67)
  • Middlewares may now contribute to the response of the "describe" operation via an optional :describe-fn function provided via their descriptors. (NREPL-64)
  • The :ns component of the response to "load-file" operations is now elided, as it was (usually) incorrect (as a result of reusing interruptible-eval for handling load-file operations) (NREPL-68)

0.2.7:

  • The topological sort ("linearization") applied to middleware provided to start a new nREPL server has been reworked to address certain edge case bugs (NREPL-53)
  • interruptible-eval no longer incorrectly clobbers a session's *ns* binding when it processes an eval message containing an ns "argument"
  • Eliminated miscellaneous reflection warnings

0.2.5:

  • Clients can now signal EOF on *in* with an empty :stdin value (NREPL-65)
  • Clojure :version-string is now included in response to a describe operation (NREPL-63)
  • Improve representation of java.version information in response to a describe operation (NREPL-62)

0.2.4:

  • Fixed the source of a reliable per-connection thread leak (NREPL-40)
  • Fix printing of lazy sequences so that *out* bindings are properly preserved (NREPL-45)
  • Enhance clojure.tools.nrepl.middleware.interruptible-eval/evaluate so that a custom eval function can be provided on a per-message basis (NREPL-50)
  • Fix pretty-printing of reference returned by clojure.tools.nrepl.server/start-server (NREPL-51)
  • nREPL now works with JDK 1.8 (NREPL-56)
  • The value of the java.version system property is now included in the response to a describe operation (NREPL-57)
  • Common session bindings (e.g. *e, *1, etc) are now set in time for nREPL middleware to access them in the case of an exception being thrown (NREPL-58)

0.2.3:

  • Now using a queue to maintain *in*, to avoid intermittent failures due to prior use of PipedReader/Writer. (NREPL-39)
  • When loading a file, always bind *print-level* and *print-length* when generating the clojure.lang.Compiler/load expression (NREPL-41)

0.2.2:

  • Added clojure.tools.nrepl/code* for pr-str'ing expressions (presumably for later evaluation)
  • session IDs are now properly combined into a set by clojure.tools.nrepl/combine-responses
  • fixes printing of server instances under Clojure 1.3.0+ (nREPL-37)

0.2.1:

  • fixes incorrect translation between Writer.write() and StringBuilder.append() APIs (NREPL-38)

0.2.0:

Top-to-bottom redesign

0.0.6:

Never released; initial prototype of "rich content" support that (in part) helped motivate a re-examination of the underlying protocol and design.

0.0.5:

  • added Clojure 1.3.0 (ALPHA) compatibility

0.0.4:

  • fixed (hacked) obtaining clojure.test output when clojure.test is initially loaded within an nREPL session
  • eliminated 1-minute default timeout on expression evaluation
  • all standard REPL var bindings are now properly established and maintained within a session
