Directly using Go's time.AfterFunc() from lua is tricky. First, it
requires the lua timer callback to explicitly lock ulua.Lock to prevent
races. Second, it requires the lua timer callback to explicitly redraw
the screen if the callback changes the screen contents (see #2923).
So instead provide micro's own timer API which ensures both
synchronization and redrawing on its own, instead of leaving this burden
to lua code. In fact, its implementation runs the lua timer callback in
the main micro's goroutine (i.e. from micro's perspective it is
synchronous, not asynchronous), so both redrawing and synchronization
are ensured automatically.
Fixes#2923
* Clarified meaning of indentchar setting
The description "sets the indentation character" combined with the default value of a space led me to believe that this was a way to set a preference for tabs/spaces and choose a number of spaces per indentation all at once. I've updated the description to try to make its true function clearer.
* Added note on rmtrailingws
This behavior was unexpected for me, so it's probably good to let other users know which option has precedence.
* Added details to help command
Initially I kept trying to use `help <command-name>` rather than `help commands`
* Added warning about ftoptions and tabstospaces
The current description for ftoptions states that it "alters some default options depending on the filetype", which hints at this behavior, but does not explicitly state it.
* Clarified specific functionality of ftoptions
Softwrap implementation enhanced to fix various issues with scrolling,
centering, relocating etc.
The main idea is simple: work not with simple line numbers but
with (Line, Row) pairs, where Line is a line number in the buffer
and Row is a visual line (a row) number within this line.
The logic remains mostly the same, but simple arithmetic operations
on line numbers are replaced with corresponding operations on
(Line, Row) pairs.
Fixes#632, #1657
Adding an S seems more intuitive here. The command you are being asked to run there completes to:
`help commands`
not `help command` as one might expect.
Although maybe help aliases might also be something to consider?
The linter and go plugins are no longer 'default'. Their installation
should be handled by the plugin manager: `> plugin install go` and
`> plugin install linter`.
The autoclose plugin will remain a default plugin because it provides
a more essential feature.
Closes#397
