# tkaer(1)

GUI tool for reviewing Aegis change sets, using TCL/TK

## NAME

tkaer - GUI tool for reviewing Aegis change sets, using TCL/TK

## SYNOPSIS

**tkaer**

## DESCRIPTION

The *tkaer* command is used to provide an easy and convenient way to review Aegis change sets. It provides a front-end to other tools which are used to view the modifications.

Files in the change set are shown in one of four lists. The choice of list is based on the operation performed on the file by the change (create, modify, move or remove). Empty lists are not shown. The change details, as provided by [*ael*(1)](/ael/1.md) may be displayed by clicking on the “Details” button.

## MODIFIED AND MOVED FILES

*tkdiff* is used to show the differenceces between the change and baseline versions of modified and moved files. (In the case of moved files, the original name is used to access the baseline version.)

Double-clicking button 1 on a filename (or pressing the space key when the filename is highlighted) will show the differences between the change and the current branch baseline. Holding down button 3 (or pressing the “a” key) will invoke a pop-up menu presenting the reviewer with a list of grandparent branches which also contain the file. This is particularly useful when rolling in branches.

## NEW AND REMOVED FILES

New files are viewed by opening a new *xterm* and using *vi* (in read-only mode) to display its contents. This method is also used for removed files, however it is the baseline version that is displayed (so that the reviewer can see what has been removed).

## ADDITIONAL FEATURES FOR REVIEWERS.

If the change is in the *being reviewed* state, the reviewer may open the comments editor by clicking on the “Comments” button. These comments will be submitted should the reviewer decide that the review has failed. An outline of the files included in the change is automatically created.

Once the review is complete, clicking the “Finished” button results in a dialog box which will allow the reviewer to pass or fail (via the [*aerpass*(1)](/aerpass/1.md) and [*aerfail*(1)](/aerfail/1.md) commands) the change. Alternatively, the reviewer may resume reviewing or quit, leaving the change state unmodified. If the change was not in the *being reviewed* state, the “Finished” button simply causes *tkaer* to exit.

## CONFIGURING TKAER

*tkaer* may be customised by the .tkaer file. This file is created by *tkaer* in the users home directory when it is first run. This newly created file contains the default configuration as described above, such as the choice of tools used in reviewing. The configuration file itself is a tcl script which is executed by the *tkaer* script using the *tcl* “source” command. Each entry takes the form of a “set” statement which adds an item to the pref array. Items currently supported are:

- **pref(diff\_command)**

  This is the tool used to visually display the difference between a changes modified or moved file and the baseline version. The default setting is

  set pref(diff\_command) "tkdiff"

  You can change it to

  set pref(diff\_command) "mgdiff"

  If you have the *mgdiff*(1) command installed.

- **pref(view\_command)**

  This is the tool used to visually display a new file or a removed files, prior contents. The default is [*vi*(1)](/vi/1.md)

- **pref(view\_edit\_font)**

  This is the font used by both the change details viewer and the review comments editor. Any available X11 font may be used.

## OPTIONS

- **-Change** *number*

  This option may be used to specify a particular change within a project. See [*aegis*(1)](/aegis/1.md) for a complete description of this option.

- **-Project** *name*

  This option may be used to select the project of interest. When no **-Project** option is specified, the *AEGIS\_PROJECT* environment variable is consulted. If that does not exist, the user's *$HOME/.aegisrc* file is examined for a default project field (see [*aeuconf*(5)](/aeuconf/5.md) for more information). If that does not exist, when the user is only working on changes within a single project, the project name defaults to that project. Otherwise, it is an error.

## EXIT STATUS

The *tkaer* command will exit with a status of 1 on any error. The *tkaer* command will only exit with a status of 0 if there are no errors.

## ENVIRONMENT VARIABLES

See [*aegis*(1)](/aegis/1.md) for a list of environment variables which may affect this command. See [*aepconf*(5)](/aepconf/5.md) for the project configuration file's *project\_specific* field for how to set environment variables for all commands executed by Aegis.
