Justin M. Keyes	fab81cfb04	lua/shared: share more stuff ... Leave trim() in vim.lua, because gen_vimdoc.py needs at least one function in there, else it gets confused...	2019-05-19 18:31:40 +02:00
Justin M. Keyes	e4c2d85c77	lua/shared: share deepcopy() with test/* ... deepcopy() was duplicated in test/helpers.lua	2019-05-19 17:58:54 +02:00
Justin M. Keyes	e628c011bf	gen_vimdoc.py: support lua/shared.lua module [ci skip]	2019-05-19 17:30:20 +02:00
KillTheMule	53576dfb35	Document the vim.lua functions	2019-05-18 22:01:14 +02:00
Justin M. Keyes	bba75eb184	lua/stdlib: Introduce vim.shared ... This is where "pure functions" can live, which can be shared by Nvim and test logic which may not have a running Nvim instance available. If in the future we use Nvim itself as the Lua engine for tests, then these functions could be moved directly onto the `vim` Lua module. closes #6580	2019-05-18 15:48:13 +02:00
Björn Linse	3a84e5be88	lua: expose full interface of vim.inspect and add test ... Implement lazy loading for vim.submodule, this would be over-engineering for inspect only, but we expect to use this solution also for more and larger modules.	2019-01-14 20:12:57 +01:00
Justin M. Keyes	6c02ff4747	lua/stdlib: Load runtime modules on-demand ... Instead of eager-loading during plugin/* sourcing, define runtime modules such as `vim.inspect` as lazy builtins. Otherwise non-builtin Lua modules such as `vim.inspect` would not be available during startup (init.vim, `-c`, `--cmd`, …). ref #6580 ref #8677	2019-01-14 02:22:16 +01:00
KillTheMule	bb3aa824b7	lua/stdlib: vim.inspect, string functions ... ref #6580 ref #8677	2019-01-14 02:14:34 +01:00
Lucas Hoffmann	4d10024a56	API: Remove path prefix from command name in nvim_get_proc() ... On macOS the output from `ps -o comm` might contain the full path of the executable. The `ucomm` would be the basename only but is less portable (see previous commit).	2018-08-18 14:37:33 +02:00
Lucas Hoffmann	794e7b4359	API: Use ps -o comm in nvim_get_proc() ... - The POSIX version of ps(1) only specifies "comm" for the "-o" option but not "ucomm". See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ps.html - On Linux (with the procps-ng package) "ucomm" is an alias for "comm". See https://gitlab.com/procps-ng/procps - OpenBSD also has "ucomm" as an alias for "comm" (with the extra note "Name to be used for accounting."). See https://man.openbsd.org/ps - FreeBSD describes "ucomm" as "Name to be used for accounting." but does not say that it should be an alias for "comm". See https://www.freebsd.org/cgi/man.cgi?query=ps	2018-08-15 12:39:10 +02:00
