This should handle most cases where Nvim was invoked as $MANPAGER.
Ultimately the stakes are low: :quit will prompt if there are unsaved
changes.
fix#7873
Many people have `runtime ftplugin/man.vim` in their init file, as was
required in Vim to have the `:Man` command generally available.
7a4d069b removed the &filetype check, which caused these setups to
always create a blank `man://` buffer.
When a file is opened by nvim with ft=man already set, and
"has('vim_starting')", ftplugin/man.vim calls
'execute 'file man://'.ref', this causes nvim to display something like
this:
````
"<name of original file>" 977, 41017C
"man://foo(1)" [Not edited] 977 lines --0%--
Press ENTER or type command to continue
````
This is annoying, because nothing of note has actually happened.
Use cases why you might want to read a man page from a file:
`MANPAGER='bash -c "nvim -c \"set ft=man\" </dev/tty <(col -bx)"' man git`
`nvim -c 'set ft=man' <(man -P cat git)`
- fix synopsis highlighting in other locales. Cannot always rely on the first
line for the section in some locales; instead, use the file path and
explicitly set b:man_sect to the actual section.
- eliminate separate s:man_args function
- simplify logic: do not reuse buffer content
- introduce b:man_default_sects Fixes#5233
- introduce <Plug>(man_vsplit), <Plug>(man_tab)
- simplify regexps
This is necessary incase the buffer was previously opened in a different
tab, in which the window options there do not carry over. It is not
explicitly documented in ':help local-options' but that is how it works.
- Weird tab+space combination used for alignment. All spaces now
- Added back <C-T> mapping (somehow we missed that completely)
- Fixed mistake that <Plug>(Man) opens in a new tab. Also added note at
top on how the window is chosen/opened.
- Clarified q local mapping
- Removed section that shows an example autocmd to add desired folding
style.
- Removed random line in `usr_12.txt` about `<Leader>` and backslash.
- :Man supports completion, not auto-completion.
Closes#5171
- Smart autocomplete. It's automatically sorted, filtered for duplicates
and even formats the candidates based on what is needed. For example,
`:Man 1 printf<TAB>` will show the pages that are in section 1m as
'page(sect)' to let you know they are in a more specific section.
- Instead of trying to unset $MANPAGER we use the -P flag to set the
pager to cat
- Always use the section arg '-s', it makes the code much simpler
(see comment in s:man-args).
- A manpage name starting with '-' is invalid. It's fine for sections
because of the use of '-s'.
- The tagstack is an actual stack now, makes it much simpler.
- By using v:count and v:count1, the plugin can explicitly check whether
the user set a count, instead of relying on a default value (0) that
is actually a real manpage section.
- Extraction of a manpage reference is much more simple. No giant long
complicated regexes. Now, the plugin lets `man` handle the actual
validation. We merely extract the section and page. Syntax regexes are
a bit more specific though to prevent highlighting everything.
- Multilingual support in the syntax file. Removed the cruft that was only
relevent to vim. Also simplified and improved many of the regexes.
- Using shellescape when sending the page and sect as arguments
- In general, the code flow is much more obvious.
- man#get_page has been split up into smaller functions with explicit
responsibilties
- ':help' behavior in opening splits and manpages
- Comments explaining anything that needs explaining and isn't
immediately obvious.
- If a manpage has already been loaded but if it were to reloaded at the
current width which is the same as the width at which it was loaded at
previously, it is not reloaded.
- Use substitute to remove the backspaced instead of `col -b`, as the
latter doesn't work with other languages.
- Open paths to manpages
- It uses cWORD instead of cword to get the manpage under the cursor, this
helps with files that do not have (,) in iskeyword. It also means the
plugin does not set iskeyword locally anymore.
- <Plug>(Man) mapping for easy remapping
- Switched to single quotes wherever possible.
- Updated docs in $VIMRUNTIME/doc/filetype.txt (still need to update
user-manual)
- Always call tolower on section name. See comment in
s:extract_page_and_sect_fpage
- Formatting/consistency cleanup
- Automatically map q to ':q<CR>' when invoked as $MANPAGER
- It also fully supports being used as $MANPAGER. Setting the name and
stuff automatically.
- Split up the setlocals into multiple lines for easier readability
- Better detection of errors by redirecting stderr to /dev/null. If an
error occured, stdout will be empty.
- Functions return [sect, page] not [page, sect]. Makes more sense with
how man takes the arguments as sect and then page.
- Pretty prints errors on a single line.
- If no section is given, automatically finds the correct section for
the buffer name. It also gets the correct page. See the comment in
s:get_page
- If $MANWIDTH is not set, do not assign directly to $MANWIDTH because
then $MANWIDTH will always stay set to the same value as we only use
winwidth(0) when the global $MANWIDTH is empty. Instead we set it
locally for the command.
- Maintainer notes on all files.
