2016-03-21vis: also lookup Lua support files relative to the binary locationMarc André Tanner5-5/+23
This simplifies deployment of vis on remote systems without root access. The idea is to extract a statically linked binary together with the lexer syntax files into some directory, adjust $PATH to include it and have everything just work. For now this uses /proc/self/exe and thus only works on Linux based systems.
2016-03-21configure: probe for hardening flagsMarc André Tanner1-1/+8
2016-03-21configure: probe for size optimizing flags (disabled for now)Marc André Tanner1-0/+3
2016-03-21build: reorder some variablesMarc André Tanner2-6/+8
2016-03-21build: create empty config.mk if it does not existMarc André Tanner1-0/+3
This should fix `make local` (as used on travis-ci) and `make standalone` in cases where `configure` was not run successfully due to missing dependencies.
2016-03-21configure: make vis depend on config.mkChristian Hesse1-1/+1
We want vis to be rebuilt when configuration changes, so make vis depend on config.mk.

2016-03-21build: overhaul build system auto detect stuff using a configure scriptMarc André Tanner6-254/+663
The new build instructions are: $ ./configure && make && sudo make install The configure script tries to auto detect support for various libraries and compiler options. These choices can be overwritten by explicitly specifing --{en,dis}able-{lua,selinux,acl}. See ./configure --help for all supported options. The configure script generates config.mk which should allow portable (among GNU and BSD make) Makefiles. Manually editing config.mk is still supported.

2016-03-15vis: do properly replay ": and "/ registersMarc André Tanner2-1/+9
This makes @: (and @/) work.

2016-03-15vis: add support for command register ":Marc André Tanner4-0/+5
2016-03-15text: improve ENOSPC handling when savingMarc André Tanner1-0/+3
The default atomic save method using rename(2) would correctly fail, but the calling code would wrongly assume it was because of dealing with a special (e.g. hard or symlink) file or that some other properties (e.g. POSIX ACL, SELinux labels, permissions etc) could not be restored. It would then go on to ftruncate(2) the file, if the following writes then fail (which is likely if the new file content is bigger or some other process has used up disk space in the mean time) we lose data. This should fix it for the common case i.e. regular file where the rename(2) based method is used. The problem persits when directly overwriting a file. It is unclear whether this could be improved/fixed by: 1) first appending the new file content to the old one 2) fsync the data (old||new) 3) deleteing the original file content by overwritting it with the previously appended new file content. That is essentially moving the new file content from the end of the file to the start. 4) ftruncate to the new file size 5) fsync the data (new) if during 1) or 2) an error would occur we could revert the operation by doing a ftruncate to the original file size. An error in steps 3-5 would still be fatal. Another option would be to first write a backup file somewhere.

2016-03-12ui/view: general code cleanupMarc André Tanner3-14/+19
2016-03-12ui: use correct default cell styleMarc André Tanner1-1/+4
This is important for files without associated syntax highlighting. The selections should now again be visible.
2016-03-12view: cleanup default ui style handlingMarc André Tanner1-28/+25
2016-03-12vis-lua: allow to set window.syntax = nilMarc André Tanner2-1/+6
This will load the default lua color theme.
2016-03-12view: also load lua theme for windows without syntax highlightingMarc André Tanner1-7/+7
This for example affects the default background color and cursor related settings.

2016-03-10vis: let <C-u> and <C-d> in visual mode move to prev/next cursorMarc André Tanner2-4/+40
We do currently not enforce a strict ordering among cursors. Hence these key bindings can move you to an arbitray position. In practice it somewhat works because most of the time cursors are created in "top-down" i.e from the start of the file towards the end.
2016-03-10view: clean up API functions related to primary cursor handlingMarc André Tanner4-10/+23
The currently visible display port is always adjusted in a way that the primary cursor is visible.

2016-03-06vis: gracefully handle lpeg module load failureMarc André Tanner1-1/+7
2016-03-06build: remove hardening compiler flags for nowMarc André Tanner1-9/+0
They do not seem to be supported on all platforms (e.g. FreeBSD). Users who know what they are doing can still provide them via the regular $CFLAGS mechanism. Eventually these should be tested by a handwritten configure script and added to config.mk iff they are supported by the toolchain.
2016-02-28build: do not modify $CFLAGS directlyMarc André Tanner1-5/+10
These are picked-up by configure when building dependencies during make standalone.
