Replacing header patterns with signature patterns was a mistake, since
both are quite different from each other, and both have their uses. In
fact, this caused a serious regression: for such files as shell scripts
without *.sh extension but with #!/bin/sh inside, filetype detection
does not work at all anymore.
Since both header and signature patterns are useful, reintroduce support
for header patterns while keeping support for signature patterns as well
and make both work nicely together.
Also, unlike in the old implementation (before signatures were
introduced), ensure that filename matches take precedence over header
matches, i.e. if there is at least one filename match found, all header
matches are ignored. This makes the behavior more deterministic and
prevents previously observed issues like #2894 and #3054: wrongly
detected filetypes caused by some overly general header patterns.
Precisely, the new behavior is:
1. if there is at least one filename match, use filename matches only
2. if there are no filename matches, use header matches
3. in both cases, try to use signatures to find the best match among
multiple filename or header matches
The original meaning of foundDef was: "we already found the final syntax
definition in a user's custom syntax file". After introducing signatures
its meaning became: "we found some potential syntax definition in a
user's custom syntax file, but we don't know yet if it's the final one".
This makes the code confusing and actually buggy.
At least one bug is that if we found some potential filename matches in
the user's custom syntax files, we don't search for more matches in the
built-in syntax files. Which is wrong: we should keep searching for as
many potential matches as possible, in both user's and built-in syntax
files, to select the best one among them.
Fix that by restoring the original meaning of foundDef and updating the
logic accordingly.
* rtfiles: Initialize all-/realFiles and Plugins in InitRuntimeFiles
* command: Reload plugins at ReloadCmd too
* command: Don't reload plugins in case of ReloadConfig()
* rtfiles: Split InitRuntimeFiles() into one func for assets and one for plugins
* rtfiles: Remove the unnecessary init function
With this modification the InitRuntimeFiles() and InitPlugins() (if needed)
must be called first, otherwise uninitialized runtime file variables are most
likely.

Handle the case when the cursor itself hasn't really moved to
another line, but its line number has changed due to insert
or remove of some lines above.
In this case, if the cursor is still at its new trailingws,
we should not reset NewTrailingWsY to -1 but update it to the
new line number.
A scenario exemplifying this issue:
Bind some key, e.g. Alt-r, to such a lua function:
function insertNewlineAbove(bp)
bp.Buf:Insert(buffer.Loc(0, bp.Cursor.Y), "\n")
end
Then in a file containing these lines:
aaa
bbb
ccc
insert a space at the end of bbb line, and then press Alt-r.
bbb and ccc are moved one line down, but also the trailing space
after bbb becomes highlighted, which isn't what we expect.
This commit fixes that.
Added option `hltrailingws` for highlighting trailing whitespaces
at the end of lines. Note that it behaves in a "smart" way.
It doesn't highlight newly added (transient) trailing whitespaces
that naturally occur while typing text. It would be annoying to
see transient highlighting every time we enter a space at the end
of a line while typing.
So a newly added trailing whitespace starts being highlighting
only after the cursor moves to another line. Thus the highlighting
serves its purpose: it draws our attention to annoying sloppy
forgotten trailing whitespaces.
* Update docs to include `matchbracestyle`

* SpawnMultiCursorUp/Down: change order of adding cursors
SpawnMultiCursor{Up,Down} currently works in a tricky way: instead of
creating a new cursor above or below, it moves the current "primary"
cursor above or below, and then creates a new cursor below or above the
new position of the current cursor (i.e. at its previous position),
creating an illusion for the user that the current (top-most or
bottom-most) cursor is a newly spawned cursor.
This trick causes at least the following issues:
- When the line above or below, where we spawn a new cursor, is shorter
than the current cursor position in the current line, the new cursor
is placed at the end of this short line (which is expected), but also
the current cursor unexpectedly changes its x position and moves
below/above the new cursor.
- When removing a cursor in RemoveMultiCursor (default Alt-p key), it
non-intuitively removes the cursor which, from the user point of view,
is not the last but the last-but-one cursor.
Fix these issues by replacing the trick with a straightforward logic:
just create the new cursor above or below the last one.
Note that this fix has a user-visible side effect: the last cursor is
no longer the "primary" one (since it is now the last in the list, not
the first), so e.g. when the user clears multicursors via Esc key, the
remaining cursor is the first one, not the last one. I assume it's ok.
* SpawnMultiCursorUp/Down: move common code to a helper fn
* SpawnMultiCursorUp/Down: honor visual width and LastVisualX
Make spawning multicursors up/down behave more similarly to cursor
movements up/down. This change fixes 2 issues at once:
- SpawnMultiCursorUp/Down doesn't take into account the visual width of
the text before the cursor, which may be different from its character
width (e.g. if it contains tabs). So e.g. if the number of tabs before
the cursor in the current line is not the same as in the new line, the
new cursor is placed at an unexpected location.
- SpawnMultiCursorUp/Down doesn't take into account the cursor's
remembered x position (LastVisualX) when e.g. spawning a new cursor
in the below line which is short than the current cursor position, and
then spawning yet another cursor in the next below line which is
longer than this short line.
* SpawnMultiCursorUp/Down: honor softwrap
When softwrap is enabled and the current line is wrapped, make
SpawnMultiCursor{Up,Down} spawn cursor in the next visual line within
this wrapped line, similarly to how we handle cursor movements up/down
within wrapped lines.
* SpawnMultiCursorUp/Down: deselect when spawning cursors
To avoid weird user experience (spawned cursors messing with selections
of existing cursors).
* Fixed newline format detection for files not ending with a newline
Files with Windows-style line endings were being converted to
Unix-style if the file did not end with a newline
* Updated file format detection fix for consistency
Similarly to the crash fixed by #2967, which happens if sudo failed,
a crash also happens when sudo even fails to start. The reason for
the crash is also similar: nil dereference of screen.Screen caused by
the fact that we do not restore temporarily disabled screen.
To reproduce this crash, set the `sucmd` option to some non-existing
command, e.g. `aaa`, and try to save a file with root privileges.
* Fix panic due to invalid regex in a syntax file
When a user's custom syntax file has a malformed filename regex or
header regex, MakeHeaderYaml() returns error but we do not properly
handle it, which results in a panic due to a dereference of the `header`
pointer which is nil:
Micro encountered an error: runtime.errorString runtime error: invalid memory address or nil pointer dereference

* Do not ignore invalid filename regex error in a syntax file
When the filename regex in a syntax file is malformed but the subsequent
header regex is correct, the filename regex error gets silently ignored,
since the `err` value is overwritten by the subsequent successful header
regex result.
On modern Linux systems, it can take 30 seconds for
the data to actually hit the disk (check
/proc/sys/vm/dirty_expire_centisecs).
If the computer crashes in those 30 seconds, the user
may end up with an empty file as seen here:
https://github.com/neovim/neovim/issues/9888
This is why editors like vim and nano call
the fsync syscall after they wrote the file.
This syscall is available as file.Sync() in Go.
Running strace against micro shows that fsync is
called as expected:
$ strace -f -p $(pgrep micro) -e fsync
strace: Process 3284344 attached with 9 threads
[pid 3284351] fsync(8) = 0
Also, we now catch errors returned from w.Flush().
* Comment fix & gofmt fix
* Goto next/previous diff commands
These commands will work in `git` repositories or whenever `set diff on` is
working. They are bound to `Alt-[` and `Alt-]` by default. I would prefer
`Alt-Up` and `Alt-Down`, but that's already taken.
There are no tests at the moment; I'm looking into writing some since that will
be needed for the rest of the plan to make
https://github.com/zyedidia/micro/discussions/2753 a reality. I'm not sure how
difficult that will be.
* Realign JSON in keybindings.md
* Support for highlighting all search matches (hlsearch)
hlsearch is implemented efficiently using the buffer's line array,
somewhat similarly to the syntax highlighting.
Unlike the syntax highlighter which highlights the entire file,
hlsearch searches for matches for the displayed lines only.
Matches are searched when the given line is displayed first time
or after it was modified. Otherwise the previously found matches
are used.
* Add UnhighlightSearch action
and add it to the list of actions triggered by Esc key by default.
* Add comment explaining the purpose of search map
* Add hlsearch colors to colorschemes
Mostly just copied from the corresponding original (mostly vim) colorschemes.
* Highlight matches during/after replace as well
As a side effect it also changes the last search value, i.e. affects FindNext
and FindPrevious, but it's probably fine. In vim it works the same way.
* Improve hlsearch option description
Modified behavior of CursorUp, CursorDown, CursorPageUp etc:
if softwrap is enabled, cursor moves by visual lines, not logical lines.
TODO: implement it also for Home and End keys: move cursor to the
visual start or end of a line. I haven't implemented it for now, because
I'm not sure what should be the behavior of StartOfTextToggle then
(considering that Home key is bound to StartOfTextToggle by default).
Fixes#1598
Fix regressions after ba98b55:
- Unable to override filetype autodetection by setting a specific filetype
for specific files, i.e. this doesn't work:
"*.h": {
"filetype": "c++"
},
- Unable to enable/disable syntax highlighting for specific files,
i.e. this doesn't work:
"*.c": {
"syntax": false
},
- "readonly" setting doesn't work (neither global nor per-filetype).
