"Contributor Version" means the combination of the Original Code, prior Modifications used by a Contributor, and the Modifications made by that particular Contributor. 77 | 78 | 1.3. "Covered Code" means the Original Code or Modifications or the combination of the Original Code and Modifications, in each case including portions thereof. 79 | 80 | 1.4. "Electronic Distribution Mechanism" means a mechanism generally accepted in the software development community for the electronic transfer of data. 81 | 82 | 1.5. "Executable" means Covered Code in any form other than Source Code. 83 | 84 | 1.6. "Initial Developer" means the individual or entity identified as the Initial Developer in the Source Code notice required by Exhibit A. 85 | 86 | 1.7. "Larger Work" means a work which combines Covered Code or portions thereof with code not governed by the terms of this License. 87 | 88 | 1.8. "License" means this document. 89 | 90 | 1.9. "Modifications" means any addition to or deletion from the substance or structure of either the Original Code or any previous Modifications. When Covered Code is released as a series of files, a 91 | Modification is: 92 | 93 | A. Any addition to or deletion from the contents of a file containing Original Code or previous Modifications. 94 | 95 | B. Any new file that contains any part of the Original Code or previous Modifications. 96 | 97 | 1.10. "Original Code" means Source Code of computer software code which is described in the Source Code notice required by Exhibit A as Original Code, and which, at the time of its release under this License is not already Covered Code governed by this License. 98 | 99 | 1.11. "Source Code" means the preferred form of the Covered Code for making modifications to it, including all modules it contains, plus any associated interface definition files, scripts used to control 100 | compilation and installation of an Executable, or a list of source code differential comparisons against either the Original Code or another well known, available Covered Code of the Contributor's choice. The Source Code can be in a compressed or archival form, provided the appropriate decompression or de-archiving software is widely available for no charge. 101 | 102 | 1.12. "You" means an individual or a legal entity exercising rights under, and complying with all of the terms of, this License or a future version of this License issued under Section 6.1. For legal entities, "You" includes any entity which controls, is controlled by, or is under common control with You. For purposes of this definition, "control" means (a) the power, direct or indirect, to cause the 103 | direction or management of such entity, whether by contract or otherwise, or (b) ownership of fifty percent (50%) or more of the outstanding shares or beneficial ownership of such entity. 104 | 105 | 2. Source Code License. 106 | 107 | 2.1. The Initial Developer Grant. 108 | The Initial Developer hereby grants You a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims: 109 | 110 | (a) to use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications, or as part of a Larger Work; and 111 | 112 | (b) under patents now or hereafter owned or controlled by Initial Developer, to make, have made, use and sell ("Utilize") the Original Code (or portions thereof), but solely to the extent that 113 | any such patent is reasonably necessary to enable You to Utilize the Original Code (or portions thereof) and not to any greater extent that may be necessary to Utilize further Modifications or 114 | combinations. 115 | 116 | 2.2. Contributor Grant. 117 | Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims: 118 | 119 | (a) to use, reproduce, modify, display, perform, sublicense and distribute the Modifications created by such Contributor (or portions thereof) either on an unmodified basis, with other Modifications, as Covered Code or as part of a Larger Work; and 120 | 121 | (b) under patents now or hereafter owned or controlled by Contributor, to Utilize the Contributor Version (or portions thereof), but solely to the extent that any such patent is reasonably necessary to enable You to Utilize the Contributor Version (or portions thereof), and not to any greater extent that 122 | may be necessary to Utilize further Modifications or combinations. 123 | 124 | 3. Distribution Obligations. 125 | 126 | 3.1. Application of License. 127 | The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or 128 | restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5. 129 | 130 | 3.2. Availability of Source Code. 131 | Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party. 132 | 133 | 3.3. Description of Modifications. 134 | You must cause all Covered Code to which you contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code. 135 | 136 | 3.4. Intellectual Property Matters 137 | 138 | (a) Third Party Claims. 139 | If You have knowledge that a party claims an intellectual property right in particular functionality or code (or its utilization under this License), you must include a text file with the source code distribution titled "LEGAL" which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If you obtain such knowledge after You make Your Modification available as described in Section 3.2, You shall promptly modify the LEGAL file in all copies You make 140 | available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained. 141 | 142 | (b) Contributor APIs. 143 | If Your Modification is an application programming interface and You own or control patents which are reasonably necessary to implement that API, you must also include this information in the LEGAL file. 144 | 145 | 3.5. Required Notices. 146 | You must duplicate the notice in Exhibit A in each file of the Source Code, and this License in any documentation for the Source Code, where You describe recipients' rights relating to Covered Code. If You created one or more Modification(s), You may add your name as a Contributor to the notice described in Exhibit A. If it is not possible to put such notice in a particular Source Code file due to its 147 | structure, then you must include such notice in a location (such as a relevant directory file) where a user would be likely to look for such a notice. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or 148 | liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of 149 | warranty, support, indemnity or liability terms You offer. 150 | 151 | 3.6. Distribution of Executable Versions. 152 | You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You 153 | describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code under a license of Your choice, which may contain terms different from this License, 154 | provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer. 155 | 156 | 3.7. Larger Works. 157 | You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code. 158 | 159 | 4. Inability to Comply Due to Statute or Regulation. 160 | 161 | If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 162 | 163 | 5. Application of this License. 164 | 165 | This License applies to code to which the Initial Developer has attached the notice in Exhibit A, and to related Covered Code. 166 | 167 | 6. Versions of the License. 168 | 169 | 6.1. New Versions. 170 | Floris van den Berg may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number. 171 | 172 | 6.2. Effect of New Versions. 173 | Once Covered Code has been published under a particular version of the License, You may always continue to use it under the terms of that version. You may also choose to use such Covered Code under the terms of any subsequent version of the License published by Floris van den Berg 174 | No one other than Floris van den Berg has the right to modify the terms applicable to Covered Code created under this License. 175 | 176 | 6.3. Derivative Works. 177 | If you create or use a modified version of this License (which you may only do in order to apply it to code which is not already Covered Code governed by this License), you must (a) rename Your license so that the phrases "FreeImage", `FreeImage Public License", "FIPL", or any confusingly similar phrase do not appear anywhere in your license and (b) otherwise make it clear that your version of the license contains terms which differ from the FreeImage Public License. (Filling in the name of the Initial Developer, Original Code or Contributor in the notice described in Exhibit A shall not of themselves be deemed to be modifications of this License.) 178 | 179 | 7. DISCLAIMER OF WARRANTY. 180 | 181 | COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. 182 | 183 | 8. TERMINATION. 184 | 185 | This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive. 186 | 187 | 9. LIMITATION OF LIABILITY. 188 | 189 | UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO YOU OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE 190 | EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. 191 | 192 | 10. U.S. GOVERNMENT END USERS. 193 | 194 | The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Code with only those rights set forth herein. 195 | 196 | 11. MISCELLANEOUS. 197 | 198 | This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by Dutch law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. With respect to disputes in which at least one party is a citizen of, or an entity chartered or registered to do business in, the The Netherlands: (a) unless otherwise agreed in writing, all disputes relating to this License (excepting any dispute relating to intellectual property rights) shall be subject to final and binding arbitration, with the losing party paying all costs of arbitration; (b) any arbitration relating to this Agreement shall be held in Almelo, The Netherlands; and (c) any litigation relating to this Agreement shall be subject to the jurisdiction of the court of Almelo, The Netherlands with the losing party responsible for costs, including without limitation, court costs and reasonable attorneys fees and expenses. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License. 199 | 200 | 12. RESPONSIBILITY FOR CLAIMS. 201 | 202 | Except in cases where another Contributor has failed to comply with Section 3.4, You are responsible for damages arising, directly or indirectly, out of Your utilization of rights under this License, based 203 | on the number of copies of Covered Code you made available, the revenues you received from utilizing such rights, and other relevant factors. You agree to work with affected parties to distribute 204 | responsibility on an equitable basis. 205 | 206 | EXHIBIT A. 207 | 208 | "The contents of this file are subject to the FreeImage Public License Version 1.0 (the "License"); you may not use this file except in compliance with the License.

If you're interested in building and running from source, the 10 | following section should help you get started. 11 | 12 | 13 | - Building and running from source 14 | 15 | Plask integrates together quite a few pieces of technology, which unfortunately 16 | makes the build process more complicated. It is possible to do a boostrapped 17 | build, where you only build the Plask source file, but use prebuilt object 18 | files for Plask's dependencies. Run the fetch_deps.sh script to download and 19 | extract a copy of these prebuilt dependencies. When fetching new source 20 | changes to Plask, you will have to be aware if there have been any changes to 21 | the prebuilt dependencies, and if so, to run fetch_deps.sh again. 22 | 23 | For example, to build from a completely new checkout would look something like: 24 | 25 | $ sh fetch_deps.sh 26 | $ xcodebuild -project plask.xcodeproj -configuration Release -target Plask 27 | 28 | This should produce Plask.app. For some technical and design reasons, Plask.app 29 | is effectively a commandline application inside a bundle. For example, running 30 | Plask.app/Contents/MacOS/Plask on the command line will start a Node-style REPL 31 | loop, an interactive JavaScript shell of sorts. 32 | 33 | Pass a filename on the command line to run that JavaScript file. 34 | 35 | NOTE: To ease development, the Plask.app built has a symlink to plask.js in 36 | the source. This allows you to edit plask.js in the source repository without 37 | having to rebuild the project. 38 | 39 | A separate project, PlaskLauncher, creates the UI application for launching 40 | Plask by dragging/dropping or File->Open. 41 | 42 | 43 | - Creating standalone applications 44 | 45 | When Plask.app is launched, it will look for a file named main.js inside of 46 | the bundle (in Contents/Resources). This allows you to easily create 47 | standalone applications by copying Plask.app and putting your JavaScript source 48 | inside of the bundle. 49 | 50 | NOTE: When running "bundled", the current working directory will likely be 51 | different from running Plask on the command line. Generally this means if you 52 | open files you should open a path relative to __dirname, which is Node's global 53 | variable for the directory that your JavaScript file is in. 54 | 55 | 56 | - Credits 57 | 58 | Released under the BSD license.

This also allows our executable to be a bit more 26 | // contained and not require nibs in the bundle. 27 | // 28 | // - We must integrate the Cocoa event loop with Node's event loop (libuv). 29 | // This requires a bit of care and the general approach follows below. 30 | // 31 | // The CFRunLoop (and Cocoa's run loop) is needed for UI messages, and needs 32 | // to be run on the main thread. We always want everything to run on the main 33 | // thread, all JavaScript, UI, etc. It would be best if we could have a 34 | // completely single threaded approach to combine the two runloops. However, 35 | // CFRunLoop is mach-port based, and can't wait on a mixture of both mach ports 36 | // and file descriptors. The way CFSocket is implemented on a CFRunLoop uses a 37 | // helper process and select() to proxy over a mach message to wake up the 38 | // CFRunLoop. Our approach is similar but managed manually. In theory it 39 | // is possible to wrap the kqueue in a CFFileDescriptor or CFSocket, and then 40 | // this would be handled within the run-loop. However, a few attempts at this 41 | // had some unreliable results, and it is clearer to handled the threading 42 | // ourselves then try to understand the implementation details of the internal 43 | // helper process of CFRunLoop(). This also allows us to send the NSEvent 44 | // required to wake up the loop directly from the helper thread, which should 45 | // be safe since postEvent can be called from "subthreads". 46 | // 47 | // There is one additional complication in terms of integrating with libuv. 48 | // We can select() on the kqueue for notifications, but we also need to make 49 | // sure that all pending changes (additions, removals, etc) from within libuv 50 | // have been committed to the kqueue. Normally this happens during the uv loop 51 | // right before blocking on the kqueue. The run through the loop can cause 52 | // timers to fire and other callbacks, which can create more new pending events 53 | // to be updated. Instead of trying to track if there are pending events and 54 | // seeing if we need to run through the loop to update the kqueue, we hook into 55 | // libuv's kevent call. This allows us to see when changes are being made and 56 | // when it's about to block. When it goes for a blocking kevent() call, we 57 | // make sure any pending changes are committed and then pump the Cocoa event 58 | // loop while our helper thread select()s on the kqueue to see if there is 59 | // anything ready. If the kqueue wakes before the Cocoa loop, we send a 60 | // synthentic event into the Cocoa loop to wake up the main thread, and we will 61 | // then again call kevent() and return back into libuv. This effectively means 62 | // we've replaced libuv's core kevent() blocking call with a call to the Cocoa 63 | // eventloop which will be woken up also if there is any activity on the 64 | // kqueue, allowing us to block on the set of both Cocoa and libuv events. 65 | 66 | #import 67 | 68 | // For kevent. 69 | #include 70 | #include 71 | #include 72 | 73 | // For select. 74 | #include 75 | 76 | #import "plaskAppDelegate.h" 77 | 78 | #include "plask_bindings.h" 79 | 80 | #include "v8.h" 81 | #include "node.h" 82 | #include "uv.h" 83 | 84 | #define EVENTLOOP_DEBUG 0 85 | 86 | #define EVENTLOOP_BYPASS_CUSTOM 0 87 | 88 | #if EVENTLOOP_DEBUG 89 | #define EVENTLOOP_DEBUG_C(x) x 90 | #else 91 | #define EVENTLOOP_DEBUG_C(x) do { } while(0) 92 | #endif 93 | 94 | static bool g_should_quit = false; 95 | static int g_kqueue_fd = 0; 96 | static int g_main_thread_pipe_fd = 0; 97 | static int g_kqueue_thread_pipe_fd = 0; 98 | 99 | // We're running nibless, so we don't have the typical MainMenu.nib.
