VIM - Passing colon-commands list via command-line - bash

Question

Good day,
I am writing a simple script within my BASHRC file to accommodate something I couldn't quite resolve in a previous question:
Side-by-side view in Vim of svn-diff for entire directory
I basically generate a list of all files which have a "Modified" SVN status. For each of these files, I want to create a side-by-side visual diff, convert it to HTML, then append it to a running HTML file.
eg:
MODIFIED_FILES="$(svn status | grep "^M" | cut -c9-)"
for i in ${MODIFIED_FILES}; do
# Generate a side-by-side diff in vim via VIMDIFF
# Convert via ToHTML
# Append the HTML file to a file called "overall_diff.html"
done
I can accomplish the vimdiff easily enough by creating a clean copy of the file, and having a copy of the modified file.
vimdiff has an issue at first, ie:
2 files to edit
Error detected while processing /Users/Owner/.vimrc:
line 45:
E474: Invalid argument: listchars=tab:>-,trail:.,extends:>,precedes:«
Press ENTER or type command to continue
So, I am trying to get past this so I don't have to hit ENTER for each file in my list.
Next, I need to have vimdiff call the ToHTML command, and then issue the command to append the HTML buffer to a running file:
:'<,'>w! >>overall_diff.html
In short, how do I:
Get past this issue with listchars when vimdiff is called. This issue doesn't occur when I run vim, so I don't know why it occurs when I run vimdiff.
Pass a list of colon-commands to VIM to have it run them at startup without requiring a change to my .vimrc file.

Answer 1

In the end, I created a separate VIMRC file that gets passed to the vim command at run time, via:
`vim -d file1 fil2 -u my_special_vimrc_file`
function createVimDiff()
{
# Create some buffers
TEMP_FILE="./tmp_file"
VIM_TEMP="./temp.html"
REVISION=""
BUFFER_FILE="./overall_diff.html"
# Get a list of the files that have changed
MODIFIED_FILES="$(svn status | grep '^M' | cut -c9-)"
# Remove buffers
rm "${BUFFER_FILE}"
for i in ${MODIFIED_FILES}; do
# Remove intermediate buffers
rm "${TEMP_FILE}"
rm "${VIM_TEMP}"
# Get the current SVN rev number for the current file
REVISION="$(svn info ${i} | grep Revision)"
# Echo the name of the file to the report
echo "FILE: ${i}" >> "${BUFFER_FILE}"
# Same with the revision number
echo "${REVISION}" >> "${BUFFER_FILE}"
echo "<br>" >> "${BUFFER_FILE}"
# First print a copy of the unmodified file in a temporary buffer
svn cat "${i}" > "${TEMP_FILE}"
# Now print the unmodified file on the left column, and the
# modified file in the right column, so they appear side-by-side
vim -d "${TEMP_FILE}" "${i}" -u ~/.vimdiff_rc
# Write the side-by-side diff to a file
cat "${VIM_TEMP}" >> "${BUFFER_FILE}"
echo "<br>" >> "${BUFFER_FILE}"
done
# Cleanup temporary buffers
rm "${TEMP_FILE}"
rm "${VIM_TEMP}"
}
And the following was put into my VIMRC file:
" Convert the diff to HTML
autocmd VimEnter * silent TOhtml
" Write output to temporary buffer
autocmd VimEnter * w! ./temp.html
" Quit VIM
autocmd VimEnter * qa!
