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).
Fix the regression after 3b34a02: setting readonly option to true
in onBufferOpen lua callback doesn't work, since it is automatically
reset to false if write permission is not denied.
In effect, pasting text with \r\n will remove the \r character and
delegate whether or not the file will be saved with CRLF or LF line
endings to the `fileformat` option.
Ref #1742
This commit introduces several improvements to the backup system.
* Backups are made every 8 seconds for buffers that have been modified
since the last backup.
* The `permbackup` option allows users to specify that backups should
be kept permanently.
* `The backupdir` option allows users to store backups in a custom
directory.
Fixes#1641Fixes#1536
Ref #1539 (removes possibility of race condition for backups)
This option is disabled by default, and when enabled causes micro
to parse `:line:col` as a location for the cursor rather than
as part of the filename.
Closes#1650Closes#1685
