2.6 Adding Files

Next Jim decides to add some files to the project. He writes up a file containing the prototypes for the JuiceBot 7:

$ mkdir include
$ cat >include/jb.h
/* Standard JuiceBot hw interface */

#define FLOW_JUICE 0x1
#define POLL_JUICE 0x2
int spoutctl(int port, int cmd, void *x);

/* JuiceBot 7 API */

#define APPLE_SPOUT 0x7e
#define BANANA_SPOUT 0x7f
void dispense_apple_juice ();
void dispense_banana_juice ();
^D

Then adds a couple skeleton source files which he wants Abe and Beth to fill in:

$ mkdir src
$ cat >src/apple.c
#include "jb.h"

void
dispense_apple_juice()
{
  /* Fill this in please, Abe. */
}
^D
$ cat >src/banana.c
#include "jb.h"

void
dispense_banana_juice()
{
  /* Fill this in please, Beth. */
}
^D

Now Jim tells monotone to add these files to its record of his workspace. He specifies one filename and one directory; monotone recursively scans the directory and adds all its files.

$ mtn add -R include/jb.h src
mtn: adding include/jb.h to workspace manifest
mtn: adding src/apple.c to workspace manifest
mtn: adding src/banana.c to workspace manifest

This command produces a record of Jim's intentions in a special file called _MTN/revision, stored in the workspace. The file is plain text:

$ cat _MTN/revision

format_version "1"

new_manifest [2098eddbe833046174de28172a813150a6cbda7b]

old_revision []

add_file "include/jb.h"
 content [3b12b2d0b31439bd50976633db1895cff8b19da0]

add_file "src/apple.c"
 content [2650ffc660dd00a08b659b883b65a060cac7e560]

add_file "src/banana.c"
 content [e8f147e5b4d5667f3228b7bba1c5c1e639f5db9f]

You will never have to look at this file, but it is nice to know that it is there.

Jim then gets up from his machine to get a coffee. When he returns he has forgotten what he was doing. He asks monotone:

$ mtn status
Current branch: jp.co.juicebot.jb7
Changes against parent :
  added   include/jb.h
  added   src/apple.c
  added   src/banana.c

The output of this command tells Jim that his edits, so far, constitute only the addition of some files.

Jim wants to see the actual details of the files he added, however, so he runs a command which prints out the status and a GNU “unified diff” of the patches involved in the changeset:

$ mtn diff
#
# old_revision []
#
# add_file "include/jb.h"
#  content [3b12b2d0b31439bd50976633db1895cff8b19da0]
#
# add_file "src/apple.c"
#  content [2650ffc660dd00a08b659b883b65a060cac7e560]
#
# add_file "src/banana.c"
#  content [e8f147e5b4d5667f3228b7bba1c5c1e639f5db9f]
