When starting [g]vim from a prompt (a cmd promt in the Dos Box or a
shell prompt in a Unix-like shell including Cygwin bash), the current
directory can be anything (I expect most often $HOME or the filesystem
root rather than $VIMRUNTIME) so in that case your getcwd() test will
disable the cd to your/preferred/startup/dir/. OTOH you may want to set
your preferred startup dir as the current directory in your preferred
shell and your desktop icon (maybe define a desktop icon with a startup
directory and another one without, to disable the cd command when
dropping a file on the latter icon).
Another possibility to avoid running a certain part of the vimrc when
re-sourcing it a 2nd (3rd, etc.) time in a vim session is the way it is
done in other plugins: in this case, put it near the end:
if exists(vimrc_started)
finish
endif
let vimrc_started = 1
" add any first-time-only commands here,
" until the end of the vimrc.
cd /my/preferred/startup/directory
Still another possibility would be to set any first-time-only commands
in an autocommand for the VimEnter event, which is triggered exactly
once in each session, at the very end of startup; but of course only if
the +autocmd feature has been compiled-in. (The above ":if" method won't
work in versions without +eval, where every ":if" is regarded as a
nestable comment, and ":let" causes an error.)
Best regards,
Tony.
