### Expand the use of colour in the IOCs output
|
|
|
|
This release includes various changes to iocsh.cpp and elsewhere to add and
|
|
expand the use of color:
|
|
|
|
- When loading a startup script, the IOC Shell now displays comment lines in
|
|
blue, and uses bold to make command lines stand out from other text.
|
|
|
|
- The `softIoc -v` output also uses the above color scheme for the commands it
|
|
prints.
|
|
|
|
- The default IOC Shell prompt is now displayed in green; this color can be
|
|
modified in the `configure/CONFIG_SITE_ENV` file for all targets, or set for
|
|
a specific target by adding a `configure/os/CONFIG_SITE_ENV.<arch>` file.
|
|
The value of the `IOCSH_PS1` environment parameter in those files can use the
|
|
`ANSI_ENV_*` and `ANSI_*()` color macros found in errlog.h to configure the
|
|
appearance of the prompt. The C string literal concatenation syntax can be
|
|
used to construct the prompt string:
|
|
|
|
```Makefile
|
|
IOCSH_PS1 = ANSI_ESC_RED "e" ANSI_ESC_YELLOW "p" ANSI_ESC_GREEN "i" \
|
|
ANSI_ESC_CYAN "c" ANSI_BLUE("s") "> "
|
|
```
|
|
|
|
- More error messages printed by IOC Shell commands now appear in red, or use
|
|
the red `ERROR` prefix that was introduced in previous releases.
|
|
|
|
- The word "Illegal" has been replaced with "Invalid" in several Shell error
|
|
messages.
|
|
|
|
- The iocsh `var` command now shows the data type of the registered variables
|
|
as well as their values.
