- CPO_ALL and CPO_VI are identical, so merge them
- No longer check for the environment variable 'VIM_POSIX'
- In vim_diff.txt, mention the removal of 'cpoptions' flags
Presumably due to tarruda's unifdefing, it was already a no-op at the
time of nvim's first commit.
It's probably better to be clear that it doesn't exist, as opposed to
users thinking `:set guipty` is doing something when it isn't.
Making an environment variable empty can be a way of unsetting it for
platforms that don't support unsetenv(). In most cases, we treat empty
variables as having been unset. For all others, use os_env_exists().
These options were never implemented in Vim. They are documented under
|missing-options| in runtime/doc/vi_diff.txt:
'autoprint'
'beautify'
'flash'
'graphic'
'hardtabs'
'mesg'
'novice'
'open'
'optimize'
'redraw'
'slowopen'
'sourceany'
'w300'
'w1200'
'w9600'

Without the casts*, the compiler rightly warns about the os_getenv
losing the qualifier. This refactor adds a variable to manage this
properly, and renames the original variables to increase clarity.
We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
Problem: Setting 'history' to a big value causes out-of-memory errors.
Solution: Limit the value to 10000. (Hirohito Higashi)

Problem: Language mapping also applies to mapped characters.
Solution: Add the 'langnoremap' option, when on 'langmap' does not apply to
mapped characters. (Christian Brabandt)

This commit integrates libvterm with Neovim and implements a terminal emulator
with nvim buffers as the display mechanism. Terminal buffers can be created
using any of the following methods:
- Opening a file with name following the "term://[${cwd}//[${pid}:]]${cmd}"
URI pattern where:
- cwd is the working directory of the process
- pid is the process id. This is just for use in session files where a pid
would have been assigned to the saved buffer title.
- cmd is the command to run
- Invoking the `:terminal` ex command
- Invoking the `termopen` function which returns a job id for automating the
terminal window.
Some extra changes were also implemented to adapt with terminal buffers. Here's
an overview:
- The `main` function now sets a BufReadCmd autocmd to intercept the term:// URI
and spawn the terminal buffer instead of reading the file.
- terminal buffers behave as if the following local buffer options were set:
- `nomodifiable`
- `swapfile`
- `undolevels=-1`
- `bufhidden=hide`
- All commands that delete buffers(`:bun`, `:bd` and `:bw`) behave the same for
terminal buffers, but only work when bang is passed(eg: `:bwipeout!`)
- A new "terminal" mode was added. A consequence is that a new set of mapping
commands were implemented with the "t" prefix(tmap, tunmap, tnoremap...)
- The `edit` function(which enters insert mode) will actually enter terminal
mode if the current buffer is a terminal
- The `put` operator was adapted to send data to the terminal instead of
modifying the buffer directly.
- A window being resized will also trigger a terminal resize if the window
displays the terminal.
This commit pulls the some environment-variable handling functions out of
misc1.c and in to os/env.c. Previously submited as #1231, this is the start of
a patch series that does that work based on a more up-to-date master branch.
Major tasks accomplished:
- move functions and fix includes
- fix clint/clang analysis warnings
- correct documentation comments
