aepromptcmd(1) aepromptcmd(1) NNAAMMEE aepromptcmd - change prompt color by change state SSYYNNOOPPSSIISS PROMPT_COMMAND="aepromptcmd" DDEESSCCRRIIPPTTIIOONN The _b_a_s_h(1) shell has an interesting property: If the PROMPT_COMMAND vaiable is set, the value is executed as a command prior to issuing each primary prompt. (Actually, it can be a seties of semicolon sepa- rated commands.) In order to change the text back to normal, the PS1 variable needs to have "\33[0m" somewhere near the end, otherwise things can get a lit- tle difficult to read. If you are using _b_a_s_h(1), you need to let it know these are unprintable (like this: "\[\33[0m\]") or it messes up command line editing. The _a_e_p_r_o_m_p_t_c_m_d command is used to set the color of the prompt, based on the state of the current change. This is an idea taken from Kent Beck's _T_e_s_t _D_r_i_v_e_n _D_e_v_e_l_o_p_m_e_n_t book. If the change is in the _b_e_i_n_g _d_e_v_e_l_o_p_e_d or _b_e_i_n_g _i_n_t_e_g_r_a_t_e_d state and it needs to be built, the prompt is red; if it is built but it needs to be tested, the prompt is magenta, otherwise it is green. EExxaammppllee Here is a short script you can put in your .bashrc file to turn on prompt coloring: if [ "$PS1" ] then case "$PROMPT_COMMAND" in "" ) PROMPT_COMMAND="aepromptcmd" PS1="$PS1^[[0m" ;; *aepromptcmd*) ;; *) PROMPT_COMMAND="$PROMPT_COMMAND;aepromptcmd" PS1="$PS1\[\33[0m\]" ;; esac export PROMPT_COMMAND export PS1 fi Note that this usually leaves your prompt default (black) when you are not somewhere inside a development directory. LLiimmiittaattiioonnss The _a_e_p_r_o_m_p_t_c_m_d command uses the ANSI color escape sequences. It really should to use the _t_i_g_e_t_s_t_r(3) function from _t_e_r_m_i_n_f_o(3) to do this in a terminal independent way. Code contributions welcome. OOPPTTIIOONNSS The following options are understood: --CChhaannggee _n_u_m_b_e_r This option may be used to specify a particular change within a project. See _a_e_g_i_s(1) for a complete description of this option. --PPrroojjeecctt _n_a_m_e This option may be used to select the project of interest. When no --PPrroojjeecctt option is specified, the _A_E_G_I_S___P_R_O_J_E_C_T envi- ronment variable is consulted. If that does not exist, the user's _$_H_O_M_E_/_._a_e_g_i_s_r_c file is examined for a default project field (see _a_e_u_c_o_n_f(5) for more information). If that does not exist, when the user is only working on changes within a sin- gle project, the project name defaults to that project. Oth- erwise, it is an error. --HHeellpp This option may be used to obtain more information about how to use the _a_e_p_r_o_m_p_t_c_m_d program. --VVeerrbboossee By default error messages are supressed, so that the prompt will be normal when you are outside an Aegis work area. Use this option to tuen error messages back on. See also _a_e_g_i_s(1) for options common to all aegis commands. All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. You must use consecutive sequences of optional letters. All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important. For example: the arguments "-project", "-PROJ" and "-p" are all inter- preted to mean the --PPrroojjeecctt option. The argument "-prj" will not be understood, because consecutive optional characters were not supplied. Options and other command line arguments may be mixed arbitrarily on the command line, after the function selectors. The GNU long option names are understood. Since all option names for _a_e_p_r_o_m_p_t_c_m_d are long, this means ignoring the extra leading '-'. The "----_o_p_t_i_o_n==_v_a_l_u_e" convention is also understood. EEXXIITT SSTTAATTUUSS The _a_e_p_r_o_m_p_t_c_m_d command will exit with a status of 1 on any error. The _a_e_p_r_o_m_p_t_c_m_d command will only exit with a status of 0 if there are no errors.

See _a_e_p_c_o_n_f(5) for the project configuration file's _p_r_o_j_e_c_t___s_p_e_c_i_f_i_c field for how to set environment variables for all commands executed by Aegis.
