Effective Date 105 | 106 | The licenses granted in Section 2.1 with respect to any Contribution 107 | become effective for each Contribution on the date the Contributor first 108 | distributes such Contribution. 109 | 110 | 2.3. Limitations on Grant Scope 111 | 112 | The licenses granted in this Section 2 are the only rights granted under 113 | this License. No additional rights or licenses will be implied from the 114 | distribution or licensing of Covered Software under this License. 115 | Notwithstanding Section 2.1(b) above, no patent license is granted by a 116 | Contributor: 117 | 118 | (a) for any code that a Contributor has removed from Covered Software; 119 | or 120 | 121 | (b) for infringements caused by: (i) Your and any other third party's 122 | modifications of Covered Software, or (ii) the combination of its 123 | Contributions with other software (except as part of its Contributor 124 | Version); or 125 | 126 | (c) under Patent Claims infringed by Covered Software in the absence of 127 | its Contributions. 128 | 129 | This License does not grant any rights in the trademarks, service marks, 130 | or logos of any Contributor (except as may be necessary to comply with 131 | the notice requirements in Section 3.4). 132 | 133 | 2.4. Subsequent Licenses 134 | 135 | No Contributor makes additional grants as a result of Your choice to 136 | distribute the Covered Software under a subsequent version of this 137 | License (see Section 10.2) or under the terms of a Secondary License (if 138 | permitted under the terms of Section 3.3). 139 | 140 | 2.5. Representation 141 | 142 | Each Contributor represents that the Contributor believes its 143 | Contributions are its original creation(s) or it has sufficient rights 144 | to grant the rights to its Contributions conveyed by this License. 145 | 146 | 2.6. Fair Use 147 | 148 | This License is not intended to limit any rights You have under 149 | applicable copyright doctrines of fair use, fair dealing, or other 150 | equivalents. 151 | 152 | 2.7. Conditions 153 | 154 | Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted 155 | in Section 2.1. 156 | 157 | 3. Responsibilities 158 | ------------------- 159 | 160 | 3.1. Distribution of Source Form 161 | 162 | All distribution of Covered Software in Source Code Form, including any 163 | Modifications that You create or to which You contribute, must be under 164 | the terms of this License. You must inform recipients that the Source 165 | Code Form of the Covered Software is governed by the terms of this 166 | License, and how they can obtain a copy of this License. You may not 167 | attempt to alter or restrict the recipients' rights in the Source Code 168 | Form. 169 | 170 | 3.2. Distribution of Executable Form 171 | 172 | If You distribute Covered Software in Executable Form then: 173 | 174 | (a) such Covered Software must also be made available in Source Code 175 | Form, as described in Section 3.1, and You must inform recipients of 176 | the Executable Form how they can obtain a copy of such Source Code 177 | Form by reasonable means in a timely manner, at a charge no more 178 | than the cost of distribution to the recipient; and 179 | 180 | (b) You may distribute such Executable Form under the terms of this 181 | License, or sublicense it under different terms, provided that the 182 | license for the Executable Form does not attempt to limit or alter 183 | the recipients' rights in the Source Code Form under this License. 184 | 185 | 3.3. Distribution of a Larger Work 186 | 187 | You may create and distribute a Larger Work under terms of Your choice, 188 | provided that You also comply with the requirements of this License for 189 | the Covered Software. If the Larger Work is a combination of Covered 190 | Software with a work governed by one or more Secondary Licenses, and the 191 | Covered Software is not Incompatible With Secondary Licenses, this 192 | License permits You to additionally distribute such Covered Software 193 | under the terms of such Secondary License(s), so that the recipient of 194 | the Larger Work may, at their option, further distribute the Covered 195 | Software under the terms of either this License or such Secondary 196 | License(s). 197 | 198 | 3.4. Notices 199 | 200 | You may not remove or alter the substance of any license notices 201 | (including copyright notices, patent notices, disclaimers of warranty, 202 | or limitations of liability) contained within the Source Code Form of 203 | the Covered Software, except that You may alter any license notices to 204 | the extent required to remedy known factual inaccuracies. 205 | 206 | 3.5. Application of Additional Terms 207 | 208 | You may choose to offer, and to charge a fee for, warranty, support, 209 | indemnity or liability obligations to one or more recipients of Covered 210 | Software. However, You may do so only on Your own behalf, and not on 211 | behalf of any Contributor. You must make it absolutely clear that any 212 | such warranty, support, indemnity, or liability obligation is offered by 213 | You alone, and You hereby agree to indemnify every Contributor for any 214 | liability incurred by such Contributor as a result of warranty, support, 215 | indemnity or liability terms You offer. You may include additional 216 | disclaimers of warranty and limitations of liability specific to any 217 | jurisdiction. 218 | 219 | 4. Inability to Comply Due to Statute or Regulation 220 | --------------------------------------------------- 221 | 222 | If it is impossible for You to comply with any of the terms of this 223 | License with respect to some or all of the Covered Software due to 224 | statute, judicial order, or regulation then You must: (a) comply with 225 | the terms of this License to the maximum extent possible; and (b) 226 | describe the limitations and the code they affect. Such description must 227 | be placed in a text file included with all distributions of the Covered 228 | Software under this License. Except to the extent prohibited by statute 229 | or regulation, such description must be sufficiently detailed for a 230 | recipient of ordinary skill to be able to understand it. 231 | 232 | 5. Termination 233 | -------------- 234 | 235 | 5.1. The rights granted under this License will terminate automatically 236 | if You fail to comply with any of its terms. However, if You become 237 | compliant, then the rights granted under this License from a particular 238 | Contributor are reinstated (a) provisionally, unless and until such 239 | Contributor explicitly and finally terminates Your grants, and (b) on an 240 | ongoing basis, if such Contributor fails to notify You of the 241 | non-compliance by some reasonable means prior to 60 days after You have 242 | come back into compliance. Moreover, Your grants from a particular 243 | Contributor are reinstated on an ongoing basis if such Contributor 244 | notifies You of the non-compliance by some reasonable means, this is the 245 | first time You have received notice of non-compliance with this License 246 | from such Contributor, and You become compliant prior to 30 days after 247 | Your receipt of the notice. 248 | 249 | 5.2. If You initiate litigation against any entity by asserting a patent 250 | infringement claim (excluding declaratory judgment actions, 251 | counter-claims, and cross-claims) alleging that a Contributor Version 252 | directly or indirectly infringes any patent, then the rights granted to 253 | You by any and all Contributors for the Covered Software under Section 254 | 2.1 of this License shall terminate. 255 | 256 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 257 | end user license agreements (excluding distributors and resellers) which 258 | have been validly granted by You or Your distributors under this License 259 | prior to termination shall survive termination. 260 | 261 | ************************************************************************ 262 | * * 263 | * 6.

Miscellaneous 314 | ---------------- 315 | 316 | This License represents the complete agreement concerning the subject 317 | matter hereof. If any provision of this License is held to be 318 | unenforceable, such provision shall be reformed only to the extent 319 | necessary to make it enforceable. Any law or regulation which provides 320 | that the language of a contract shall be construed against the drafter 321 | shall not be used to construe this License against a Contributor. 322 | 323 | 10. Versions of the License 324 | --------------------------- 325 | 326 | 10.1. New Versions 327 | 328 | Mozilla Foundation is the license steward. Except as provided in Section 329 | 10.3, no one other than the license steward has the right to modify or 330 | publish new versions of this License. Each version will be given a 331 | distinguishing version number. 332 | 333 | 10.2. Effect of New Versions 334 | 335 | You may distribute the Covered Software under the terms of the version 336 | of the License under which You originally received the Covered Software, 337 | or under the terms of any subsequent version published by the license 338 | steward. 339 | 340 | 10.3. Modified Versions 341 | 342 | If you create software not governed by this License, and you want to 343 | create a new license for such software, you may create and use a 344 | modified version of this License if you rename the license and remove 345 | any references to the name of the license steward (except to note that 346 | such modified license differs from this License). 347 | 348 | 10.4. Distributing Source Code Form that is Incompatible With Secondary 349 | Licenses 350 | 351 | If You choose to distribute Source Code Form that is Incompatible With 352 | Secondary Licenses under the terms of this version of the License, the 353 | notice described in Exhibit B of this License must be attached. 354 | 355 | Exhibit A - Source Code Form License Notice 356 | ------------------------------------------- 357 | 358 | This Source Code Form is subject to the terms of the Mozilla Public 359 | License, v. 2.0. If a copy of the MPL was not distributed with this 360 | file, You can obtain one at http://mozilla.org/MPL/2.0/. 361 | 362 | If it is not possible or desirable to put the notice in a particular 363 | file, then You may include the notice in a location (such as a LICENSE 364 | file in a relevant directory) where a recipient would be likely to look 365 | for such a notice. 366 | 367 | You may add additional accurate notices of copyright ownership. 368 | 369 | Exhibit B - "Incompatible With Secondary Licenses" Notice 370 | --------------------------------------------------------- 371 | 372 | This Source Code Form is "Incompatible With Secondary Licenses", as 373 | defined by the Mozilla Public License, v. 2.0. 374 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # lambdaisland/nrepl-proxy 2 | 3 | 4 | [![cljdoc badge](https://cljdoc.org/badge/com.lambdaisland/nrepl-proxy)](https://cljdoc.org/d/com.lambdaisland/nrepl-proxy) [![Clojars Project](https://img.shields.io/clojars/v/com.lambdaisland/nrepl-proxy.svg)](https://clojars.org/com.lambdaisland/nrepl-proxy) 5 | 6 | 7 | Proxy server for debugging nREPL 8 | 9 | ## Usage 10 | 11 | Running inside this project or in a project where lambdaisland.nrepl-proxy 12 | has been added to deps.edn: 13 | ``` 14 | clojure -X lambdaisland.nrepl-proxy/start :port 1234 :attach 5678 15 | ``` 16 | 17 | Running if from anywhere: 18 | ``` 19 | clojure -Sdeps '{:deps {com.lambdaisland/nrepl-proxy {:mvn/version "0.2.8-alpha"}}}' -X lambdaisland.nrepl-proxy/start :port 1234 :attach 5678 20 | ``` 21 | 22 | This will listen for incoming connections on port 1234, and will connect through 23 | to an nREPL server listening on port 5678. When it gets a connection it prints 24 | out something like this: 25 | 26 | ``` 27 | nil ---> 1 clone {} 28 | J <=== 1 #{:done} {:new-session "002914a8-db79-408d-807a-c5b3955ab6f9"} 29 | nil ---> 2 clone {} 30 | X <=== 2 #{:done} {:new-session "6a7e7b99-1b8e-4008-bbe5-ddddf46672a9"} 31 | Y ---> 3 describe {} 32 | Y <=== 3 #{:done} {:aux {:current-ns "user"}, :ops {:stdin {}, :add-middleware {}, :lookup {}, :swap-middleware {}, :sideloader-start {}, :ls-middleware {}, :close {}, :sideloader-provide {}, :load-file {}, :ls-sessions {}, :clone {}, :describe {}, :interrupt {}, :completions {}, :eval {}}, :versions {:clojure {:incremental 3, :major 1, :minor 10, :version-string "1.10.3"}, :java {:version-string "17"}, :nrepl {:incremental 0, :major 0, :minor 9, :version-string "0.9.0"}}} 33 | Y ---> 4 eval {:nrepl.middleware.print/buffer-size 4096, :file "*cider-repl lambdaisland/nrepl-proxy:localhost:5424(clj)*", :nrepl.middleware.print/quota 1048576, :nrepl.middleware.print/print "cider.nrepl.pprint/pprint", :column 1, :line 10, :code "(clojure.core/apply clojure.core/require clojure.main/repl-requires)", :inhibit-cider-middleware "true", :nrepl.middleware.print/stream?

Responses marked as `:done` get 43 | a thick arrow, `:error` responses get a `<***` arrow. 44 | 45 | Then you get the message id, the `:op` for sent messages, or the `:status` flags 46 | for returning messages, and then the map with other keys. 47 | 48 | This is meant as a PoC for tooling that wants to make nREPL traffic 49 | introspectable. 50 | 51 | 52 | ## Lambda Island Open Source 53 | 54 | 55 | 56 |   57 | 58 | nrepl-proxy is part of a growing collection of quality Clojure libraries created and maintained 59 | by the fine folks at [Gaiwan](https://gaiwan.co). 60 | 61 | Pay it forward by [becoming a backer on our Open Collective](http://opencollective.com/lambda-island), 62 | so that we may continue to enjoy a thriving Clojure ecosystem. 63 | 64 | You can find an overview of our projects at [lambdaisland/open-source](https://github.com/lambdaisland/open-source). 65 | 66 |   67 | 68 |   69 | 70 | 71 | 72 | ## Contributing 73 | 74 | Everyone has a right to submit patches to nrepl-proxy, and thus become a contributor. 75 | 76 | Contributors MUST 77 | 78 | - adhere to the [LambdaIsland Clojure Style Guide](https://nextjournal.com/lambdaisland/clojure-style-guide) 79 | - write patches that solve a problem. Start by stating the problem, then supply a minimal solution. `*` 80 | - agree to license their contributions as MPL 2.0. 81 | - not break the contract with downstream consumers. `**` 82 | - not break the tests. 83 | 84 | Contributors SHOULD 85 | 86 | - update the CHANGELOG and README. 87 | - add tests for new functionality. 88 | 89 | If you submit a pull request that adheres to these rules, then it will almost 90 | certainly be merged immediately. However some things may require more 91 | consideration. If you add new dependencies, or significantly increase the API 92 | surface, then we need to decide if these changes are in line with the project's 93 | goals. In this case you can start by [writing a pitch](https://nextjournal.com/lambdaisland/pitch-template), 94 | and collecting feedback on it. 95 | 96 | `*` This goes for features too, a feature needs to solve a problem. State the problem it solves, then supply a minimal solution. 97 | 98 | `**` As long as this project has not seen a public release (i.e. is not on Clojars) 99 | we may still consider making breaking changes, if there is consensus that the 100 | changes are justified. 101 | 102 | 103 | 104 | ## License 105 | 106 | Copyright © 2021 Arne Brasseur and Contributors 107 | 108 | Licensed under the term of the Mozilla Public License 2.0, see LICENSE. 109 | 110 | -------------------------------------------------------------------------------- /bb.edn: -------------------------------------------------------------------------------- 1 | {:deps 2 | {lambdaisland/open-source {:git/url "https://github.com/lambdaisland/open-source" 3 | :git/sha "5cc6e89c24662d60ca215c645388f79154adfb00" 4 | #_#_:local/root "../open-source"}}} 5 | -------------------------------------------------------------------------------- /bin/kaocha: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | clojure -A:test -m kaocha.runner "$@" 3 | -------------------------------------------------------------------------------- /bin/proj: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bb 2 | 3 | (ns proj 4 | (:require [lioss.main :as lioss])) 5 | 6 | (lioss/main 7 | {:license :mpl 8 | :inception-year 2021 9 | :description "Proxy server for debugging nREPL interactions" 10 | :version-qualifier "alpha" 11 | :group-id "com.lambdaisland"}) 12 | 13 | ;; Local Variables: 14 | ;; mode:clojure 15 | ;; End: 16 | -------------------------------------------------------------------------------- /deps.edn: -------------------------------------------------------------------------------- 1 | {:deps 2 | { 3 | nrepl/nrepl {:mvn/version "1.0.0"} 4 | ;; lambdaisland/funnel-client {:mvn/version "0.0.13"} 5 | commons-io/commons-io {:mvn/version "2.11.0"} 6 | }} 7 | -------------------------------------------------------------------------------- /dev/user.clj: -------------------------------------------------------------------------------- 1 | (ns user) 2 | 3 | (defmacro jit [sym] 4 | `(requiring-resolve '~sym)) 5 | 6 | (defn browse [] 7 | ((jit clojure.java.browse/browse-url) "http://localhost:8000")) 8 | 9 | (def portal-instance (atom nil)) 10 | 11 | (defn portal 12 | "Open a Portal window and register a tap handler for it.
