Save vimdiff output to html

The script ( vimdiff_to_html.sh ) matches the filename from first directory to same filename from second directory and takes a difference between two files using vimdiff and saves a html of diff into output directory under the matching name of the filename

for example, out put of below command, “vimdiff first/a.c second/a.c” will be saved as html in out/a/Diff.html

 vim vimdiff_to_html.sh 
[bash] #!/bin/bash TOP_DIR=$PWD DIR1=first DIR2=second FILE_SEPERATOR="$DIR1/" FILE_EXTENTION=".c" SEARCH_FILE_TYPES="*.c" REPORTS=out #cleanup any previous reports rm -rf $REPORTS for f in $(find $DIR1 -name "$SEARCH_FILE_TYPES") do echo "file found is $f" file_with_extention=${f#*$FILE_SEPERATOR} file_without_extention=${file_with_extention%$FILE_EXTENTION} #remove extention echo "file name for directory is $file_without_extention" mkdir -p $REPORTS/$file_without_extention cd $REPORTS/$file_without_extention #to save output Diff.html is respective directory vimdiff $TOP_DIR/$f $TOP_DIR/$DIR2/$file_with_extention -c ":TOhtml" -c ":wq!" cd $TOP_DIR #back to top dir for next iteration done [/bash]

To demonestrate, the working of above script, we create two directories “first” and “second”, both of this directories will have same file “a.c” but there will be difference in source code, which we want to identify and save to html.

mkdir first
vim first/a.c 
[bash] #include <stdio.h> int main(void) { int a; printf("Hello World\n"); return 0; } [/bash]
mkdir second
vim second/a.c 
[bash] #include <stdio.h> int main(int argc, char **argv) { int a; printf("Hello World\n"); a = 10; return 0; } [/bash]

and we will create a “out” directory where the script will save the difference html.

Now, lets run the script as,

 bash vimdiff_to_html.sh 

Above script will auto exit and create a file as,

$ tree out/
out/
└── a
    └── Diff.html

Now, if we open this DIff.html using any browser, it will show as,

vimdiff 2 html

Above is a automated script , which inside use a simple command as below,

vimdiff first/a.c second/a.c -c :TOhtml -c :wq! 

You may use above command to generate html for single file.
