2017-01-10vis-lua: expose valid marks as vis:mark_names()Marc André Tanner
2016-12-31vis: allow user registered :-commands to specify a help textMarc André Tanner
2016-12-29vis-lua: allow vis:map to set up key aliases and actionsMarc André Tanner
2016-12-29vis-lua: introduce vis:action_registerMarc André Tanner
2016-12-29vis: cleanup key action lifetime managementMarc André Tanner
2016-12-29vis-lua: simplify lua function reference handlingMarc André Tanner
2016-12-29vis-lua: luaL_checkstring already checks for NULL return valueMarc André Tanner
2016-12-27vis: properly free dynamic key bindingsMarc André Tanner
The handling of :unmap needs to be revisited at some point.
2016-12-22vis-lua: store Vis context in upvalues where neededMarc André Tanner
2016-12-22text: change datatype of Mark to uintptr_tMarc André Tanner
This should avoid undefined pointer comparisons.
2016-12-19vis-lua: implement vis.registers[] arrayMarc André Tanner
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-lua: simplify obj_ref_new error handlingMarc André Tanner
2016-12-19vis-lua: simplify object reference checkingMarc André Tanner
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 Tanner
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 Tanner
2016-12-13build: add configure options for built-in lpeg supportMarc André Tanner
2016-12-12Allow building lpeg into visMichael Forney
If lpeg is built statically, this allows for a completely static vis binary that still supports syntax highlighting.
2016-12-09vis-lua: add generic way to expose C text objects to LuaMarc André Tanner
Expose text_object_word as an example.
2016-12-09vis-lua: add comment about possibly outdated Lua API documentationMarc André Tanner
2016-12-09vis-lua: expose input key event in insert and replace modesMarc André Tanner
2016-12-08vis-lua: only fail file_save_pre event if explicitly returned falseMarc André Tanner
Previously we would also interpret a missing return value `nil` as is the case when no pre save event handler is subscribed as failure.
2016-12-08vis-lua: move mode constants from vis.MODE_* to vis.modes.*Marc André Tanner
2016-12-08vis-lua: add optional help parameter to mapping functionsMarc André Tanner
2016-12-08vis-lua: expose init event and use it to set default themeMarc André Tanner
The init event is emitted immediately after `visrc.lua` has been sourced, but before any other events have occured, in particular the command line arguments have not yet been processed. Close #422
2016-12-08lua: add simple event multiplexing mechanismMarc André Tanner
The editor core calls into the functions registered in the `vis.events` table which then multiplex the events to all registered event handlers. The first handler which returns a non `nil` value terminates event propagation.
2016-12-07Move all lua related files to lua/ subfolderMarc André Tanner
Also remove the lexers sub directory from the Lua search path. As a result we attempt to open fewer files during startup: $ strace -e open -o log ./vis +q config.h && wc -l log In order to avoid having to modifiy all lexers which `require('lexer')` we instead place a symlink in the top level directory. $ ./configure --disable-lua $ rm -rf lua Should result in a source tree with most lua specifc functionality removed.
2016-12-06vis-lua: more extensive Lua API documentationMarc André Tanner
2016-12-05vis-lua: add preliminary version of LDoc based Lua API documentationMarc André Tanner
A new Makefile target `luadoc` has been added which generates HTML documentation in the doc subfolder using ldoc(1) from https://stevedonovan.github.io/ldoc/ There are still a few problems to resovle, for example the links (e.g. in parameter lists) to our custom types seem to be broken. At this point only the C part of the Lua API is covered and even that is not yet complete.
2016-11-28vis-lua: add file.path property denoting the absolute path to the fileMarc André Tanner
Close #407
2016-11-27vis-lua: lua_pushtring already takes care of NULL stringMarc André Tanner
2016-11-22vis-lua: introduce pre-save hookMarc André Tanner
The first argument is the file object while the second argument denotes the full path to which it will be written. Path might be `nil` if the file is going to be written to stdout. The Lua function is expected to return a boolean value indicating whether the write operation should proceed or be aborted.
2016-11-22vis-lua: pass path as second argument to file_save_post event hookMarc André Tanner
The passed path can be different from file.name for instance when opening a file `a` and then doing `:w b` where file.name will be the former and path the latter.
2016-11-21vis-lua: rename file_save event to file_save_postMarc André Tanner
Indicating that the event is triggered *after* a successfull write.
2016-11-14vis-lua: add vis.ui.colors denoting the number of available colorsMarc André Tanner
2016-11-10vis: fix compilation with Lua support disabledMarc André Tanner
2016-11-10vis: change default status bar indication for Windows style line endingsMarc André Tanner
2016-11-10vis-lua: change misnamed attribute values of `file.newlines`Marc André Tanner
Also rename underlying C code.
2016-11-05vis: display Lua package.cpath in :help outputMarc André Tanner
These paths are used to load the Lua LPeg module (lpeg.so) and are thus helpful when diagnosing setup problems in case syntax highlighting does not work.
2016-10-05Fix various issues reported by coverity scanMarc André Tanner
2016-09-19vis-lua: expose file save event to luaMarc André Tanner
Triggered after the new file content has been written to disk.
2016-09-19vis-lua: expose file open event to luaMarc André Tanner
The event is only triggerred for new files read from disk (e.g. splitting an existing window will not cause an event to be emitted).
2016-08-24vis-lua: add win:draw() functionMarc André Tanner
2016-05-26vis: use normalized absolute file names as internal representationMarc André Tanner
Try to display a shorthand version in the status bar, this currently only works for files below the current working directory of the editor process.
