# Overview

The following developer tools are available, each one with its own `loader.lgt` loader file (except for the built-in `linter` and `make` tools, which are integrated with the compiler/runtime) and `NOTES.md` documentation files:

- `asdf`

- `assertions`

- `code_metrics`

- `dead_code_scanner`

- `debug_messages`

- `debugger`

- `diagrams`

- `doclet`

- `help`

- `issue_creator`

- `lgtdoc`

- `lgtunit`

- `linter`

- `make`

- `packs`

- `ports_profiler`

- `profiler`

- `tutor`

- `wrapper`

## Loading the developer tools

To load the main developer tools, use the following goal:

    | ?- logtalk_load(tools(loader)).

The `ports_profiler` tool is not loaded by default, however, as it conflicts with the `debugger` tool as both provide a debug handler that must be unique in a running session.

The `profiler` tool is also not loaded by default as it provides integration with selected backend Prolog compiler profilers that are not portable.

The `tutor` tool is also not loaded by default given its useful mainly for new users that need help understanding compiler warning and error messages.

The `wrapper` tool is also not loaded by default given its specialized purpose and beta status.

To load a specific tool, either change your Prolog working directory to the tool folder and then compile and load the corresponding loader utility file or simply use library notation as argument for the compiling and loading predicates. For example:

    | ?- logtalk_load(lgtunit(loader)).

## Tools documentation

Specific notes about each tool can be found in the corresponding `NOTES.md` files. HTML documentation for each tool API can be found on the `docs` directory (open the `../docs/index.html` file with your web browser). The documentation for these tools can be regenerated using the shell scripts `../scripts/update_html_docs.sh` and `../scripts/update_svg_diagrams.sh`.

## Tools common flags

The `lgtdoc` and `lgtunit` tools share a `suppress_path_prefix` flag that can be used to suppress a prefix when printing file paths. For example (after loading the tools):

    | ?- set_logtalk_flag(suppress_path_prefix, '/home/jdoe/').

## Tools requirements

Some of the developer tools have third-party dependencies. For example, the `lgtdoc` tool depends on XSLT processors to generate documentation final formats and uses Sphinx for the preferred HTML final format. Be sure to consult the tools documentation details on those requirements and possible alternatives. For convenience, follows a global list of the main tool requirements and suggestions for installing them per operating-system. If your operating-system or a dependency for it is not listed, see the dependency websites for installation instructions.
