2016-12-27vis: properly free dynamic key bindingsMarc André Tanner6-7/+44
The handling of :unmap needs to be revisited at some point.
2016-12-27array: implement array_removeMarc André Tanner2-0/+14
2016-12-27travis: install 9baseMarc André Tanner1-0/+5
This should enable sam related tests for Linux builds.
2016-12-27build: configure ncurses with --disable-leaksMarc André Tanner1-1/+1
Makes analysis with valgrind easier.
2016-12-27build: pass $CFLAGS_EXTRA through make debug targetMarc André Tanner1-1/+1
2016-12-26fix help text for next/prev matchErlend Fagerheim1-2/+2
2016-12-23text-objects: explicitly ignore return value of strtoll(3)Marc André Tanner1-1/+1
We are only interested in the first invalid character.
2016-12-23Apply format string attribute to printf style functionsMarc André Tanner3-6/+6
Not strictly C99 conform, but widely supported and easy enough to NOP for compilers which do not support it. Besides it was already used to mark certain functions as noreturn.
2016-12-23text: make text_vprintf static, it is only used within text.cMarc André Tanner2-14/+13
2016-12-22text: remove Filepos typedefMarc André Tanner2-5/+3
The idea might be good, but it was almost unused.
2016-12-22text: introduce EMARK to denote an invalid markMarc André Tanner3-5/+7
Technically this macro name is in the reserved namespace of errno.h. The same is true for EPOS. Maybe we should rename them at some point, but for now the short names are convenient. Fix #443 Close #444
2016-12-22test: updateMarc André Tanner1-5/+8
2016-12-22vis-lua: store Vis context in upvalues where neededMarc André Tanner1-5/+8
2016-12-22text: change datatype of Mark to uintptr_tMarc André Tanner6-14/+17
This should avoid undefined pointer comparisons.
2016-12-22text: make default block size overridable via C pre-processorMarc André Tanner1-0/+2
This will be used for unit test purposes to force more allocations.
2016-12-22buffer: make default buffer size overridable via C pre-processorMarc André Tanner1-3/+5
2016-12-22text: avoid undefined multiple accesses in expressionMarc André Tanner1-1/+2
Work around for a (bogus?) tis-interpreter warning.
2016-12-22text: do not rely on indeterminate value in a comparisonMarc André Tanner1-1/+1
2016-12-22build: do not install lua/doc directoryMarc André Tanner1-0/+1
2016-12-22build: also include working tree state in version informationMarc André Tanner1-1/+1
2016-12-21vis: implement `gh` and `gl` to move by relative byte offsetsMarc André Tanner4-0/+36
2016-12-21vis: implement `go` to move to absolute byte positionMarc André Tanner4-0/+18
2016-12-21vis: implement g8Marc André Tanner2-4/+16
Shows hex values up to the next UTF-8 encoded character.
2016-12-20vis: improve literal insertion via <C-v> in insert modeMarc André Tanner3-21/+50
2016-12-20vis: improve gaMarc André Tanner1-9/+20
2016-12-20ui: increase maximum info message lengthMarc André Tanner1-1/+1
2016-12-20buffer: implement buffer_capacity utility functionMarc André Tanner2-0/+6
2016-12-20buffer: implement buffer_appendf to append formatted contentMarc André Tanner2-15/+26
2016-12-20buffer: fix error case in buffer_append0Marc André Tanner1-3/+6
Do not change buffer length when failing to append.
2016-12-19vis-lua: implement vis.registers[] arrayMarc André Tanner1-1/+58
Notice that currently only single letter register names/array indices are supported. Register handling needs to be cleaned up at some point.
2016-12-19vis: introduce vis_register_from utility functionMarc André Tanner3-37/+37
2016-12-19vis-lua: simplify obj_ref_new error handlingMarc André Tanner1-10/+9
2016-12-19vis-lua: simplify object reference checkingMarc André Tanner1-163/+58
Make obj_ref_check handle invalid object references. The luaL_argerror function throws a Lua error and never returns, hence all return value checks become obsolete.
2016-12-19vis-lua: implement file.marks[] arrayMarc André Tanner1-0/+65
We need to retrieve a pointer to the File struct but can not store it directly in the Lua uservalue because the address is already used for the regular file object (of type vis.file). For now we use file->marks as an address and then use offsetof to retrieve the start of the struct.
2016-12-19vis-lua: implement file:mark_{get,set}Marc André Tanner1-0/+38
2016-12-17test: updateMarc André Tanner1-5/+5
2016-12-17vis: allow boolean :set options to be toggledMarc André Tanner2-13/+32
Boolean options can be toggled by appending `!` to the option name. Close #435
2016-12-17vis: always remove consumed keys from input queueMarc André Tanner1-3/+3
When given a mapping like: :map! insert >> ><>x> whose end is a prefix of another mapping we should still remove all already consumed keys from the input queue. Fixes #436
2016-12-16travis: try to enable code coverage for test/coreMarc André Tanner1-1/+1
2016-12-16build: update unused make standalone/local Lua reference to 5.3.3Marc André Tanner1-2/+2
2016-12-16vis: process keys following an unmatched prefix individuallyMarc André Tanner1-1/+3
Fixes #434
2016-12-16vis: add section about compile time configuration to :help outputMarc André Tanner1-0/+15
2016-12-15build: move $CFLAGS_DEBUG into config.mkMarc André Tanner2-9/+6
This allows inclusion in other Makefiles (e.g. for C unit tests).
2016-12-15vis: always store registers values NUL terminatedMarc André Tanner1-4/+6
Previously we only made sure that the register content is NUL terminated when reading it out. This made it impossible to distinguish between an empty register and one which stores a single NUL byte. Now the in memory representation of a non-empty register is always NUL terminated. When appending we temporarily remove the trailing NUL byte and restore it later. This should fix put commands of a previously yanked single NUL byte.
2016-12-15vis: respect terminating NUL bytes in the input queueMarc André Tanner1-1/+1
It can happen that the Buffer content used for the input queue becomes <\000> where the NUL byte is intended to terminate the queue, but termkey happily parses it and because it is delimited by < and > on both sides we then interpret it as a key. In input mode this leads to the insertion of a NUL byte which is displayed as ^@. Close #432
2016-12-15vis: more informative error message for :set optionJosh Wainwright1-1/+1
Close #433
2016-12-14lua: make sure we always load a default themeMarc André Tanner2-1/+2
2016-12-14lua: improve error message when failing to load lpeg/lexer moduleMarc André Tanner2-9/+22
Differentiate between the case where the module is not found and the case where an error occured while loading it. This should make it easier to debug cases in which there is a Lua version mismatch between vis and lpeg.
2016-12-14vis: remove useless NULL checkMarc André Tanner1-1/+1
The very first thing we do if that check is false, is return from the function.
2016-12-14build: improve description of --enable-lpeg configure optionMarc André Tanner1-1/+1
It links lpeg statically into the vis binary, meaning it does not need to be dlopen(3)-ed at runtime. While this improves the portability of the resulting vis binary, it is not necessary to enable this option to get syntax highlighting support. Maybe the option should be renamed to avoid further confusion.
