hi,

just found out that there is a problem if I use NERDTreeMirror and save that as a session ...

best regards

ST

i installed this plugin without any modification
commands all run well
but just no autosave/load even i enabled the opts.
echo checked in vim, they are set to 1
but still no luck...
anything i miss?
what i put in my vimrc is:

let g:session_autosave = 1
let g:session_autoload = 1

also tried;

let g:session_command_aliases = 1
let g:session_directory = "~/.vim_runtime/sessions"
let g:session_autoload = 'yes'
let g:session_autosave = 'yes'

no luck..
thanks

I've noticed that this plugin doesn't work well with vimwiki plugin
(http://www.vim.org/scripts/script.php?script_id=2226) - it corrupt some of
the mappings.

Steps to reproduce de fault:

1. :e temp.wiki -> by default vimwiki will create some normal mode mappings
   for some commands, such as 'O' and 'gqq'.

2. insert some text, save the file and the session with :SaveSession testWiki

3. either call :RestartVim or close the current instance of Vim and load the
   session testWiki

4. normal 'O' now inserts nmap \wr VimwikiRenameLink"
   instead of new line, while 'gqq' doesn't format the line and gives an
   error.

With this error:

Not sure if other people have gotten this but using sessions with ConqueTerm it wont work. It'll just leave a blank buffer instead of where I was in the command session. Thanks for the plugins! They rock!

I am using your plugins session and easytags (and the following folder names for it: easytags, session and vim-misc).

When using "vim-misc" as "vim-misc", but "vim-session" as "session" in the bundle folder, the following error is triggered:

Error detected while processing function <SNR>41_InitEasyTags..<SNR>41_CheckCtags..xolox#misc#os#exec:

line  121:

I guess that it is related to easytags using the xolox#misc functions from the session plugin.
Renaming session to vim-session works around this.

:RestartVim stopped working since version 2.3.1 (f1cb34e).

I've tested on Windows with a fresh gVim installation, and after issuing the command this error message is displayed:

  session.vim 2.3.2: Saved global session 'default' to ~\vimfiles\sessions\default.vim.
  session.vim 2.3.2: Closed global session 'default'.
  Error detected while processing function xolox#session#restart_cmd:
  line   23:
  E371: Command not found

It seems that problem can be traced to commit 5ad0d15, which introduces xolox#misc#os#find_vim(). The problem is that it is returning an empty string.

I recall using this command in the past and it doesn't seem to be working now. When I type :RestartVim in Macvim, the tabs close, an error message blinks in the bottom area and then vim just closes. On the plus side, everything seems to be saving correctly.

I uploaded a gist of the debug output for mvim -v9error.log. There's more to the log file, but I'm pretty sure this is the part where :RestartVim is called.

Hi,

At the moment I set marks with mX and when reloading the session, these marks are gone :(

Hello,

What do you think about add some menu entries (for gvim)?
For example, I have:
amenu 10.321 &File.Open\ Session\.\.\. :OpenSession<CR>

What about to add something like this to core plugin?

I have no idea it doesnt work :( i looked at the doc's known issues( https://github.com/xolox/vim-session/blob/master/doc/session.txt#L465 ) but couldn't find anything out.

I don't like to remember to much command in different plugin, so my customization is change

Action + 'Session'

To

'Session'+Action

The benefit is autocomplete in console, and rotate the commands. Maybe we can just add some command alias to keep the back compatibility.

Here is my folk :

https://github.com/genewoo/vim-session/commits/master

It would be great if g:session_directory would respect a trailing //, the same way that the built-in dir does. That way, I could just keep the sessions for all my projects in a central location, the way I do with swap and backup files.

In case you're not familiar with this option, this is in :help dir:

For Unix and Win32, if a directory ends in two path separators "//" or "", the swap file name will be built from the complete path to the file with all path separators substituted to percent '%' signs. This will ensure file name uniqueness in the preserve directory. On Win32, when a separating comma is following, you must use "//", since "" will include the comma in the file name.

(This would be an alternative of solving the use case I presented in #22.)

I have a use case that doesn't seem too unusual that would be incredibly useful to myself: usually, I don't want to make a default.vim session in any directory I happen to open vim in, otherwise I litter my clean directories with sessions from random times I needed vim open. On the other hand, if I have been using sessions (e.g. default.vim exists) I would like the autosave functionality to be "yes" so that when I quit, default.vim reflects the state of vim before exiting.

In essence, a fourth option of "ifexists", which acts like "no" if there isn't a default.vim in the current directory, and "yes" if there is one. This way, I don't litter my drive with sessions files, but get the autosave functionality where I have explicitly called SaveSession before.

vim-session is currently not working with vim 7.0 because of the missing haslocaldir() function.

I got it to work by changing the line

if haslocaldir()

to

if exists("*haslocaldir") && haslocaldir()

in autoload.vim.

Hello. After I've updated vim-session plugin I have an error popup on my gvim startup with following message:

for example, if I'm at
~/projects/first_project/

vim-session will auto load session from ~/projects/first_project/.vimsession

In issue #19 @diego898 reports the following two unrelated problems:

Things seem to be working although there is two slightly strange things:

• The current directory on NERDTree is not saved with the session. It always starts on ~/myname/Desktop, the directory I make gvim start out of by the shortcut I use. Vim's cwd changes quickly however, due to things in my vimrc that makes its current directory match that of the open file.
• Upon startup, both nerdtree and the file that is shown (correctly coming over from my last session which is good) are both shown at their very very bottom. In other words, a file with lines 1-30, starts with line 30 at the very top of my screen with vim showing me ~ for 70 lines? NERDTree also starts "too high" as it were. A quick gg fixes it, just found it a little strange.

Since these are new problems I'm closing #19 and using this new issue to keep track of them instead.

vim-session does not currently mark a session as dirty if the working directory changes. This means that if I open a session, 'cd' (or 'lcd') and then close the session, the updated session, with new working directory, will not be saved.

Out of curiosity, what is the reason for the dirty flag? Is it mainly so that users with autosave disabled won't get spurious save prompts?

My current thinking is that this feature may cause more problems than it solves. Dirty checks only check if the buffer list or layout have changed, which misses a lot of options that get saved with the session.

I install this plugin with pathogen
vim version is 7.3.1136

in autoload session.vim

if is_all_tabs
    call add(a:commands, 'set guioptions=' . escape(&go, ' "\'))
    call add(a:commands, 'silent! set guifont=' . escape(&gfn, ' "\'))
endif

please add guioptions and guifont only when gui_running or gui_macvim

in terminal vim save session will lose gui info

and please add macvim when check gui_running by gui_macvim

The plugin shouldn't save [BufExplorer] buffer made by BufExplorer plugin (https://github.com/vim-scripts/bufexplorer.zip.git). The plugin warns 'The buffer name was [[BufExplorer]] so it was skipped.' when you try to activate [BufExplorer] buffer.

Similar to the other BufExplorer and TagBar issues, MiniBufExplorer creates a special -MiniBufExplorer- buffer that creates problems when restoring sessions. It works fine with bare Vim sessions, so I guess if you just skip saving this buffer it should work?

If I have:

let $TODAYS_DATE = strftime('%b_%d')

in my .vimrc file,

I'd like to be able to run

:SessionSave $TODAYS_DATE

and result in a Aug_17.vim file instead of a $TODAYS_DATE.vim file.

emacs can do it:)

hi - I use the solarized theme which is configured in this way:

set t_Co=256
set background=dark
let g:solarized_termcolors=256
colorscheme solarized

after loading a session with OpenSession, the background is set to light instead of dark -
is there a way to save also the background variable?

when no session is open and there are no existing sessions then when the user quits vim without invoking :SaveSession it would be nice if the plugin asked him whether he wants to save the current environment as a session. or it could silently store the environment as the 'default' session (based on some option).

this change will enable the following scenario: you download vim-session, install it, put some lines into your .vimrc and forget about the plugin. also some users might forget to invoke :SaveSession for the first time and thus lose their environment.

in autoload / xolox / session.vim, if is_all_tabs, xolox#session#save_colors(a:commands) has been called,

add an option let savesession not call this.

This commit aadb3a2 cause some troubles to me. Every time I saved a session, it added an empty buffer in the beginning. Does it the normal behavior?

Could you put the MIME type (.zip) into the download URL (currently it just says http://peterodding.com/code/vim/downloads/session)? That would make it much easier to integrate it in Janus without any special installation scripting. Another solution would be to have the full content on GitHub. As when I just copy those files (autoload.vim and session.vim) it doesn't seem to work.

I'd love to have an option to configure the default name vim-session uses.

My use case: I'd like to only use vim-session when I'm working on big projects, and I'd like to save a session per project. I'm using g:session_directory = '.' to save the session to the project directory, but I want to have the name be a dotfile that I can easily ignore (and also put in my global gitignore). I manually changed the name of the default in my own fork but it would be great if this were an option.

I installed the plugin with Vundle using Bundle 'xolox/vim-session in my ~/.vimrc file, but, since the last time I ran the command to update all the plugins, every time I open Vim, I get this errors:

When I open a file without a session specified, make a quick edit and then close a file. I expect that when I start gvim with no parameters that it will start back up a default session with that file I was editing.

This does not appear to happen. An explicit SaveSession works great, but not the automatic save.

My pertinent vimrc settings are:

let g:session_autoload = 'yes'
let g:session_autosave = 'yes'
let g:session_autosave_periodic = 2
let g:session_default_to_last = 1
set sessionoptions-=help

Cheers!

Right now i have a session that's over 800 lines... I've been working on this client project awhile, and that's the output of many many days of opening and closing the same session.

in fact, scarily:

% grep -c badd redstamp.vim 
829

I don't really want this many buffers open. :(

i've resorted to deleting the session, and starting again -- but i wonder, could you consider -- if there's any way? to be able to rebuild/reset the session with whatever is currently in view? I don't need hidden or unloaded buffers, for example, nor do i want to have settings that i've set, unset, etc.

or another best case way of doing it?

Hi, your plugin is great, thanks for it. This is a feature request.
I compiled vim my self and run it from a non standard location, i made sure theres always a $VIMRUNTIME enviromental variable.
When using :RestartVim it opens a new vim without my .vimrc loaded. This file is in the standard place ~/.vimrc
I tried debugging the function that does the restart but it is beyond my skills.
I made symlinks of my vim binaries to /usr/local/bin with the default names vim and gvim.
Thanks again.

TagBar (https://github.com/majutsushi/tagbar) creates buffer TagBar that also should be treated specially.

First of all I'd thank you for this great plugin!

I mainly use this plugin with its default session and option g:session_autoload set to 'yes'.
So when I open the first gVim instance the plugin brings the default session, and if I open more instances of gVim the plugin doesn't open any session.

The problem happens when I issue :RestartSession to restart the default session. The command executes correctly, but when I try to open new instances of gVim they try to open the default session. It seems that RestartSession doesn't set the session lock. Issuing SaveSession solve the problem, but it is a little bit annoying.

I'm having issues on default installation of this plugin.

Steps to reproduce my issue:

1. Install latest plugin (via pathogen + git clone)

2. gvim /tmp/test.txt

3. :w
4. :SaveSession (session.vim 1.7: Saved 'default' session to ~/.vim/sessions/default.vim.)
5. :q

6. gvim

During gvim startup I see an error message:

Hi,

I found when I opened multiple files for editing, but didn't create a new window or tab, the session wasn't marked as dirty and therefore wasn't saved on exit.

Replacing WinEnter with BufEnter on line 65 of session.vim should solve the problem.

Mark

Every time I Use the OpenSession command to restore a previous saved session, the last file I used comes as an empty and duplicated file. I have to delete the buffer and select the one that works. Is a little anoying. I'm using buffergator just in case it has something to do.

Thanks

After did the update, whenever I tried to open vim it always gives me this errro:

I call OpenSession as soon as vim starts to resume my previous editing session.

Everything looks OK -- my NERDTree window comes back fine, and my editor pane comes back but my syntax highlighting is not automatically enabled. :set filetype returns nothing.

If I open a file with vim directly, the filetype does get appropriately set, just not when resuming a session.

Updated to cfc5bdf today — not sure from what, just something relatively recent. Since then I get on starting vim (7.3.1030 on Arch Linux):

When open a nerdtree window and save session and quite vim, then open vim open that session, the nerdtree's left window will open, but is a blank window.

I normally browse with NERDTree open in the current project folder. NERDTree sits in its own tab (at tab position 0) and I open each project file in a new tab.

Using either :SaveSession or autosave, I can reload my last session, but one tab is missing--the one next to the NERDTree tab.

If I keep a file open in the same tab as NERDTree, this doesn't seem to happen.
