You can also distribute + unmodified parts of Vim, likewise unrestricted except that they must + include this license text. You are also allowed to include executables + that you made from the unmodified Vim sources, plus your own usage + examples and Vim scripts. + +II) It is allowed to distribute a modified (or extended) version of Vim, + including executables and/or source code, when the following four + conditions are met: + 1) This license text must be included unmodified. + 2) The modified Vim must be distributed in one of the following five ways: + a) If you make changes to Vim yourself, you must clearly describe in + the distribution how to contact you. When the maintainer asks you + (in any way) for a copy of the modified Vim you distributed, you + must make your changes, including source code, available to the + maintainer without fee. The maintainer reserves the right to + include your changes in the official version of Vim. What the + maintainer will do with your changes and under what license they + will be distributed is negotiable. If there has been no negotiation + then this license, or a later version, also applies to your changes. + The current maintainer is Bram Moolenaar . If this + changes it will be announced in appropriate places (most likely + vim.sf.net, www.vim.org and/or comp.editors). When it is completely + impossible to contact the maintainer, the obligation to send him + your changes ceases. Once the maintainer has confirmed that he has + received your changes they will not have to be sent again. + b) If you have received a modified Vim that was distributed as + mentioned under a) you are allowed to further distribute it + unmodified, as mentioned at I). If you make additional changes the + text under a) applies to those changes. + c) Provide all the changes, including source code, with every copy of + the modified Vim you distribute. This may be done in the form of a + context diff. You can choose what license to use for new code you + add. The changes and their license must not restrict others from + making their own changes to the official version of Vim. + d) When you have a modified Vim which includes changes as mentioned + under c), you can distribute it without the source code for the + changes if the following three conditions are met: + - The license that applies to the changes permits you to distribute + the changes to the Vim maintainer without fee or restriction, and + permits the Vim maintainer to include the changes in the official + version of Vim without fee or restriction. + - You keep the changes for at least three years after last + distributing the corresponding modified Vim. When the maintainer + or someone who you distributed the modified Vim to asks you (in + any way) for the changes within this period, you must make them + available to him. + - You clearly describe in the distribution how to contact you. This + contact information must remain valid for at least three years + after last distributing the corresponding modified Vim, or as long + as possible. + e) When the GNU General Public License (GPL) applies to the changes, + you can distribute the modified Vim under the GNU GPL version 2 or + any later version. + 3) A message must be added, at least in the output of the ":version" + command and in the intro screen, such that the user of the modified Vim + is able to see that it was modified. When distributing as mentioned + under 2)e) adding the message is only required for as far as this does + not conflict with the license used for the changes. + 4) The contact information as required under 2)a) and 2)d) must not be + removed or changed, except that the person himself can make + corrections. + +III) If you distribute a modified version of Vim, you are encouraged to use + the Vim license for your changes and make them available to the + maintainer, including the source code. The preferred way to do this is + by e-mail or by uploading the files to a server and e-mailing the URL. + If the number of changes is small (e.g., a modified Makefile) e-mailing a + context diff will do. The e-mail address to be used is + + +IV) It is not allowed to remove this license from the distribution of the Vim + sources, parts of it or from a modified version. You may use this + license for previous Vim releases instead of the license that they came + with, at your option. diff --git a/syntax/bc.vim b/syntax/bc.vim new file mode 100644 index 0000000..fe520be --- /dev/null +++ b/syntax/bc.vim @@ -0,0 +1,77 @@ +" Vim syntax file +" Language: bc - An arbitrary precision calculator language +" Maintainer: Vladimir Scholtz +" Last change: 2020 Apr 17 +" (Dominique Pelle added @Spell) +" (Gavin D.
