haltcl — manipulate the LinuxCNC HAL from the command line using a tcl interpeter.
haltcl [-i inifile] [filename]
haltcl is used to manipulate the HAL (Hardware Abstraction
Layer) from the command line using a tcl interpreter.
haltcl can optionally read commands from a file (filename), allowing complex HAL configurations to be set up with a single command.
If specified, the inifile is read and used to create tcl global variable arrays. An array is created for each SECTION of the inifile with elements for each ITEM in the section.
For example, if the inifile contains: [SECTION_A]ITEM_1 = 1 [SECTION_A]ITEM_2 = 2 [SECTION_B]ITEM_1 = 1 The corresponding tcl variables are: SECTION_A(ITEM_1) = 1 SECTION_A(ITEM_2) = 2 SECTION_B(ITEM_1) = 1
-ini inifile — declining usage, use -i inifile
If specified, the tcl commands of filename are executed. If no filename is specified, haltcl opens an interactive session.
haltcl includes the commands of a tcl interpreter augmented with
commands for the hal language as described for halcmd.
The augmented commands can be listed with the command:
haltcl: hal --commands addf alias delf delsig getp gets ptype stype help linkpp linkps linksp list loadrt loadusr lock net newsig save setexact_for_test_suite_only setp sets show source start status stop unalias unlinkp unload unloadrt unloadusr unlock waitusr
Two of the augmented commands,
gets, require special treatment to
avoid conflict with tcl built-in commands having the same names. To use these
commands, precede them with the keyword
hal list hal gets
