* Add server side ncurses terminalest312015-11-06
| | | | | | | | | | | | | | | | | | | | | | | | This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection.
* FindJson: use PATH_SUFFIXES jsoncpp to find incdirIgor Gnatenko2015-09-26
| | | | For example, on Fedora systems jsoncpp headers is installed in `/usr/include/jsoncpp`.
* Add LibGMPest312015-05-11
| | | | Uses system provided libgmp if found, if not it falls back to mini-gmp.
* Make Git version detection use VERSION_STRING instead of tagsShadowNinja2015-05-05
| | | | | | | | | | This fixes the problem where 0.4.12-dev versions were erroneously shown as 0.4.11-dev because the tag was added on a separate branch. It also fixes a similar issue when builders didn't fetch new tags when updating. This also removes the number-of-commits-since-tag field, since it's incompatible with this. Said field doesn't seem to be useful anyway if you have the commit hash.

* Fix cmake po detection bugest312015-03-23
| | | | Previously, cmake po detection would treat the "timestamp" file created by building for android as own language directory.
* Improve FindIrrlicht.cmake moduleMarkus Koschany2015-02-21
| | | | | | | | | Linux distributions prefer to link against a shared version of the Irrlicht engine instead of using embedded code copies of the same. Search for this shared version first and use that but fall back to the static version if it does not exist. This also fixes https://github.com/minetest/minetest/issues/2163

* Bring po update out of cmake againGiuseppe Bilotta2011-07-24
| | | | | | | | | | | | | | This solves two issues at once: * CMake would delete po files during ‘make clean’ because it thought they were autogenerated and not just managed * the only gettext tools readily available in Windows are so old they don't support options like --package-name The change also moves minetest.pot down one level, so we don't need to special case ‘en’ anymore. The downside is of course that you need some sane POSIX shell to update the po files.
* updated cmakerules to autodetect if gettext can be usedConstantin Wenger2011-07-23

* updatepo cmake ruleGiuseppe Bilotta2011-07-22
| | | | | | | | | | Get rid of the system-specific updatelocales.sh and introduce an updatepo cmake rule. po files are also updated before creating the mo files, and we now keep the .pot file (in the po/en directory). To stabilize the po file creation, file contents are sorted by source filename. Update po files in the process.
