15 | This is not a command the end user would want to run. Ever. |
| 16 | This documentation is meant for people who are studying the | |
| 17 | Porcelain-ish scripts and/or are writing new ones. | |
| 18 | ||
| 19 | The `git-sh-setup` scriptlet is designed to be sourced (using | |
| 20 | `.`) by other shell scripts to set up some variables pointing at | |
| 21 | the normal git directories and a few helper shell functions. | |
| 22 | ||
| 23 | Before sourcing it, your script should set up a few variables; | |
| 24 | `USAGE` (and `LONG_USAGE`, if any) is used to define message | |
| 25 | given by `usage()` shell function. `SUBDIRECTORY_OK` can be set | |
| 26 | if the script can run from a subdirectory of the working tree | |
| 27 | (some commands do not). | |
| 28 | ||
| 29 | The scriptlet sets `GIT_DIR` and `GIT_OBJECT_DIRECTORY` shell | |
| 30 | variables, but does *not* export them to the environment. | |
| 31 | ||
| 32 | FUNCTIONS | |
| 33 | --------- | |
| 34 | ||
| 35 | die:: | |
| 36 | exit after emitting the supplied error message to the | |
| 37 | standard error stream. | |
| 38 | ||
| 39 | usage:: | |
| 40 | die with the usage message. | |
| 41 | ||
| 42 | set_reflog_action:: | |
| 43 | set the message that will be recorded to describe the | |
| 44 | end-user action in the reflog, when the script updates a | |
| 45 | ref. | |
| 46 | ||
| 47 | is_bare_repository:: | |
| 48 | outputs `true` or `false` to the standard output stream | |
| 49 | to indicate if the repository is a bare repository | |
| 50 | (i.e. without an associated working tree). | |
| 51 | ||
| 52 | cd_to_toplevel:: | |
| 53 | runs chdir to the toplevel of the working tree. | |
| 54 | ||
| 55 | require_work_tree:: | |
| 56 | checks if the repository is a bare repository, and dies | |
| 57 | if so. Used by scripts that require working tree | |
| 58 | (e.g. `checkout`). | |
