ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM 3 | CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT. 4 | 5 | 1. DEFINITIONS 6 | 7 | "Contribution" means: 8 | 9 | a) in the case of the initial Contributor, the initial code and 10 | documentation distributed under this Agreement, and 11 | 12 | b) in the case of each subsequent Contributor: 13 | 14 | i) changes to the Program, and 15 | 16 | ii) additions to the Program; 17 | 18 | where such changes and/or additions to the Program originate from and are 19 | distributed by that particular Contributor. A Contribution 'originates' from 20 | a Contributor if it was added to the Program by such Contributor itself or 21 | anyone acting on such Contributor's behalf. Contributions do not include 22 | additions to the Program which: (i) are separate modules of software 23 | distributed in conjunction with the Program under their own license 24 | agreement, and (ii) are not derivative works of the Program. 25 | 26 | "Contributor" means any person or entity that distributes the Program. 27 | 28 | "Licensed Patents" mean patent claims licensable by a Contributor which are 29 | necessarily infringed by the use or sale of its Contribution alone or when 30 | combined with the Program. 31 | 32 | "Program" means the Contributions distributed in accordance with this 33 | Agreement. 34 | 35 | "Recipient" means anyone who receives the Program under this Agreement, 36 | including all Contributors. 37 | 38 | 2. GRANT OF RIGHTS 39 | 40 | a) Subject to the terms of this Agreement, each Contributor hereby grants 41 | Recipient a non-exclusive, worldwide, royalty-free copyright license to 42 | reproduce, prepare derivative works of, publicly display, publicly perform, 43 | distribute and sublicense the Contribution of such Contributor, if any, and 44 | such derivative works, in source code and object code form. 45 | 46 | b) Subject to the terms of this Agreement, each Contributor hereby grants 47 | Recipient a non-exclusive, worldwide, royalty-free patent license under 48 | Licensed Patents to make, use, sell, offer to sell, import and otherwise 49 | transfer the Contribution of such Contributor, if any, in source code and 50 | object code form. This patent license shall apply to the combination of the 51 | Contribution and the Program if, at the time the Contribution is added by the 52 | Contributor, such addition of the Contribution causes such combination to be 53 | covered by the Licensed Patents. The patent license shall not apply to any 54 | other combinations which include the Contribution. No hardware per se is 55 | licensed hereunder. 56 | 57 | c) Recipient understands that although each Contributor grants the licenses 58 | to its Contributions set forth herein, no assurances are provided by any 59 | Contributor that the Program does not infringe the patent or other 60 | intellectual property rights of any other entity. Each Contributor disclaims 61 | any liability to Recipient for claims brought by any other entity based on 62 | infringement of intellectual property rights or otherwise. As a condition to 63 | exercising the rights and licenses granted hereunder, each Recipient hereby 64 | assumes sole responsibility to secure any other intellectual property rights 65 | needed, if any. For example, if a third party patent license is required to 66 | allow Recipient to distribute the Program, it is Recipient's responsibility 67 | to acquire that license before distributing the Program. 68 | 69 | d) Each Contributor represents that to its knowledge it has sufficient 70 | copyright rights in its Contribution, if any, to grant the copyright license 71 | set forth in this Agreement. 72 | 73 | 3. REQUIREMENTS 74 | 75 | A Contributor may choose to distribute the Program in object code form under 76 | its own license agreement, provided that: 77 | 78 | a) it complies with the terms and conditions of this Agreement; and 79 | 80 | b) its license agreement: 81 | 82 | i) effectively disclaims on behalf of all Contributors all warranties and 83 | conditions, express and implied, including warranties or conditions of title 84 | and non-infringement, and implied warranties or conditions of merchantability 85 | and fitness for a particular purpose; 86 | 87 | ii) effectively excludes on behalf of all Contributors all liability for 88 | damages, including direct, indirect, special, incidental and consequential 89 | damages, such as lost profits; 90 | 91 | iii) states that any provisions which differ from this Agreement are offered 92 | by that Contributor alone and not by any other party; and 93 | 94 | iv) states that source code for the Program is available from such 95 | Contributor, and informs licensees how to obtain it in a reasonable manner on 96 | or through a medium customarily used for software exchange. 97 | 98 | When the Program is made available in source code form: 99 | 100 | a) it must be made available under this Agreement; and 101 | 102 | b) a copy of this Agreement must be included with each copy of the Program. 103 | 104 | Contributors may not remove or alter any copyright notices contained within 105 | the Program. 106 | 107 | Each Contributor must identify itself as the originator of its Contribution, 108 | if any, in a manner that reasonably allows subsequent Recipients to identify 109 | the originator of the Contribution. 110 | 111 | 4. COMMERCIAL DISTRIBUTION 112 | 113 | Commercial distributors of software may accept certain responsibilities with 114 | respect to end users, business partners and the like. While this license is 115 | intended to facilitate the commercial use of the Program, the Contributor who 116 | includes the Program in a commercial product offering should do so in a 117 | manner which does not create potential liability for other Contributors. 118 | Therefore, if a Contributor includes the Program in a commercial product 119 | offering, such Contributor ("Commercial Contributor") hereby agrees to defend 120 | and indemnify every other Contributor ("Indemnified Contributor") against any 121 | losses, damages and costs (collectively "Losses") arising from claims, 122 | lawsuits and other legal actions brought by a third party against the 123 | Indemnified Contributor to the extent caused by the acts or omissions of such 124 | Commercial Contributor in connection with its distribution of the Program in 125 | a commercial product offering. The obligations in this section do not apply 126 | to any claims or Losses relating to any actual or alleged intellectual 127 | property infringement. In order to qualify, an Indemnified Contributor must: 128 | a) promptly notify the Commercial Contributor in writing of such claim, and 129 | b) allow the Commercial Contributor tocontrol, and cooperate with the 130 | Commercial Contributor in, the defense and any related settlement 131 | negotiations. The Indemnified Contributor may participate in any such claim 132 | at its own expense. 133 | 134 | For example, a Contributor might include the Program in a commercial product 135 | offering, Product X. That Contributor is then a Commercial Contributor. If 136 | that Commercial Contributor then makes performance claims, or offers 137 | warranties related to Product X, those performance claims and warranties are 138 | such Commercial Contributor's responsibility alone. Under this section, the 139 | Commercial Contributor would have to defend claims against the other 140 | Contributors related to those performance claims and warranties, and if a 141 | court requires any other Contributor to pay any damages as a result, the 142 | Commercial Contributor must pay those damages. 143 | 144 | 5. NO WARRANTY 145 | 146 | EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON 147 | AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER 148 | EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR 149 | CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A 150 | PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the 151 | appropriateness of using and distributing the Program and assumes all risks 152 | associated with its exercise of rights under this Agreement , including but 153 | not limited to the risks and costs of program errors, compliance with 154 | applicable laws, damage to or loss of data, programs or equipment, and 155 | unavailability or interruption of operations. 156 | 157 | 6. DISCLAIMER OF LIABILITY 158 | 159 | EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY 160 | CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, 161 | SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION 162 | LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN 163 | CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) 164 | ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE 165 | EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY 166 | OF SUCH DAMAGES. 167 | 168 | 7. GENERAL 169 | 170 | If any provision of this Agreement is invalid or unenforceable under 171 | applicable law, it shall not affect the validity or enforceability of the 172 | remainder of the terms of this Agreement, and without further action by the 173 | parties hereto, such provision shall be reformed to the minimum extent 174 | necessary to make such provision valid and enforceable. 175 | 176 | If Recipient institutes patent litigation against any entity (including a 177 | cross-claim or counterclaim in a lawsuit) alleging that the Program itself 178 | (excluding combinations of the Program with other software or hardware) 179 | infringes such Recipient's patent(s), then such Recipient's rights granted 180 | under Section 2(b) shall terminate as of the date such litigation is filed. 181 | 182 | All Recipient's rights under this Agreement shall terminate if it fails to 183 | comply with any of the material terms or conditions of this Agreement and 184 | does not cure such failure in a reasonable period of time after becoming 185 | aware of such noncompliance. If all Recipient's rights under this Agreement 186 | terminate, Recipient agrees to cease use and distribution of the Program as 187 | soon as reasonably practicable. However, Recipient's obligations under this 188 | Agreement and any licenses granted by Recipient relating to the Program shall 189 | continue and survive. 190 | 191 | Everyone is permitted to copy and distribute copies of this Agreement, but in 192 | order to avoid inconsistency the Agreement is copyrighted and may only be 193 | modified in the following manner. The Agreement Steward reserves the right to 194 | publish new versions (including revisions) of this Agreement from time to 195 | time. No one other than the Agreement Steward has the right to modify this 196 | Agreement. The Eclipse Foundation is the initial Agreement Steward. The 197 | Eclipse Foundation may assign the responsibility to serve as the Agreement 198 | Steward to a suitable separate entity. Each new version of the Agreement will 199 | be given a distinguishing version number. The Program (including 200 | Contributions) may always be distributed subject to the version of the 201 | Agreement under which it was received. In addition, after a new version of 202 | the Agreement is published, Contributor may elect to distribute the Program 203 | (including its Contributions) under the new version. Except as expressly 204 | stated in Sections 2(a) and 2(b) above, Recipient receives no rights or 205 | licenses to the intellectual property of any Contributor under this 206 | Agreement, whether expressly, by implication, estoppel or otherwise. All 207 | rights in the Program not expressly granted under this Agreement are 208 | reserved. 209 | 210 | This Agreement is governed by the laws of the State of New York and the 211 | intellectual property laws of the United States of America. No party to this 212 | Agreement will bring a legal action under this Agreement more than one year 213 | after the cause of action arose. Each party waives its rights to a jury trial 214 | in any resulting litigation. 215 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | ## clojure-unicode 2 | 3 | Clojure library that binds rich Unicode symbols to traditional clojure.core macros and operations. 4 | 5 | ### Usage 6 | 7 | ``` 8 | :dependencies [ 9 | [clojure.unicode "0.2.1"] 10 | ] 11 | ``` 12 | 13 | ```clj 14 | (use clojure.unicode) 15 | 16 | (≠ 1 2) ;; ⇒ true 17 | (¬ false) ;; ⇒ true 18 | (∧ true false) ;; ⇒ false 19 | (∨ true false) ;; ⇒ true 20 | 21 | (× 1 2 3) ;; ⇒ 6 22 | (÷ 1 2) ;; ⇒ 1/2 23 | (− 1) ;; ⇒ -1 24 | (≤ 1 2 2 3) ;; ⇒ true 25 | (≥ 4 2 2 0) ;; ⇒ true 26 | (≡ 1 1 1) ;; ⇒ true 27 | (≢ 1 1 2) ;; ⇒ true 28 | (< 1 ∞) ;; ⇒ true 29 | (∑ (range 0 5)) ;; ⇒ 10 30 | (∏ (range 1 5)) ;; ⇒ 24 31 | 32 | (∋ #{1 2 3} 1) ;; ⇒ true 33 | (∌ #{1 2 3} 5) ;; ⇒ true 34 | (∈ 1 #{1 2 3}) ;; ⇒ true 35 | (∉ 5 #{1 2 3}) ;; ⇒ true 36 | (∀ odd? #{1 5 3}) ;; ⇒ true 37 | (∃ even?
