NAME

SYNOPSIS

DESCRIPTION

Because when you type a command, you know your intent. The command execution is just a thing to achieve your goal. This program takes the command which was executed, and try to find out what the intent was to run that command. It deduces the semantic of the command.

This is useful to generate a compilation database. Citnames get a list of commands, and it creates a JSON compilation database. (This is currently the only output of the tool.)

OPTIONS

--version

Print version number.

--help

Print help message.

--verbose

Enable verbose logging.

--input file

Specify input file. (Default file name provided.) The input is a command execution list, with some extra information. The syntax is detailed in a separate section.

--output file

Specify output file. (Default file name provided.) The output is currently a JSON compilation database.

--append

Use previously generated output file and append the new entries to it. This way you can run continuously during work, and it keeps the compilation database up to date. File deletion and addition are both considered. But build process change (compiler flags change) might cause duplicate entries.

--run-checks

Allow the program to verify file location checks on the current machine it runs. (Default value provided. Run help to query it.) This is important if the execution list is not from the current host.

--config file

Specify a configuration file. The configuration file captures how the output should be formatted and which entries it shall contain.

EXIT STATUS

OBSERVABILITY

INPUT FILE

Read more about the syntax of the file in the intercept man page.

OUTPUT FILE

CONFIG FILE

The config file is optional. The program will use default values, which can be dumped with the --verbose flags.

Some parts of the file has overlap with the command line arguments. If both present the command line argument overrides the config file values.

compilation.compilers_to_recognize

where compiler can be specified, which are not yet recognized by default. The executable is an absolute path to the compiler. The flags_to_add is an optional attribute, which contains flags which will append to the final output. (It’s a good candidate to use this for adding OpenMPI compiler wrapper flags from the mpicc --showme:compile output.) The flags_to_remove is an optional attribute, where the given flags will be removed for the final argument list. (The flags checked for equality only, no regex match. Flags with arguments are not good candidates to put here, because the removal logic is too simple for that.)

compilation.compilers_to_exclude

this is an optional list of executables (with absolute path) which needs to be removed from the output.

output.content

The paths_to_include and paths_to_exclude are for filter out entries from these directories. (Directory names can be absolute paths or relative to the current working directory if the --run-checks flag passed.) The include_only_existing_source allows or disables file check for the output. The --run-checks flag overrides this config value.

output.format

The command_as_array controls which command field is emitted in the output. True produces arguments, false produces command field. The drop_output_field will disable the output field from the output.
