That is, gEDA/gaf v1.9.0 which was released in December 2012. By the way, is there usage information beyond the man page? The command "gaf config" is not transparent to me, yet. According to the man page it is used like this: gaf config [OPTION] [GROUP KEY [VALUE]] But what options, group keys and values can this be used with? What job is this config meant to do? What tricks can be achieved? Anybody got some examples or use cases? ---<)kaimartin(>--- PS: Here is a copy of the man page: /------------------------------------------------------ NAME gaf - gEDA/gaf Command-Line Utility SYNOPSIS gaf [OPTION ...] COMMAND [ARGS ...] DESCRIPTION gaf is part of the gEDA (GPL Electronic Design Automation) toolset. It provides a number of small command-line utilities for working with schematic and symbol files, and is designed to be used for batch processing of designs created using the schematic editor gschem(1). It currently has three built-in COM‐ MANDs: gaf export is used to create SVG, PDF, PNG, PS and EPS files from schematic and symbol files, for printing or embedding in other documents. gaf config allows reading and writing settings in gEDA project, user and system configuration stores. gaf shell provides a Scheme REPL for command-line batch process‐ ing of schematic data. GENERAL OPTIONS --no-rcfiles Prevent `gafrc' Scheme initialisation files from being loaded. -h, --help Print a help message. -V, --version Print gaf version information. EXPORTING IMAGE FILES gaf export [OPTION ...] -o OUTPUT [--] FILE ... gaf export can export schematic and symbol files in a variety of image formats for printing or further processing. It currently supports single-page PNG, SVG and EPS output, and multi-page PS and PDF output. It accepts a variety of options for controlling how the output is formatted. -o, --output=FILE Output generated image data to FILE. -f, --format=(png | pdf | svg | ps | eps) Specify an output format. Usually, this option is not required, because gaf export will infer the correct for‐ mat from the file extension of the output file. -p, --paper=NAME Size the output for a particular paper size. The NAME should be a PWG 5101.1-2002 paper name. For example, valid values include `iso_a4', `na_letter', or `na_d'. -l, --layout=(auto | landscape | portrait) When using a paper size, set the orientation of the out‐ put. If `auto' layout is used, the orientation that best fits the drawing will be used. -s, --size=(auto | WIDTH:HEIGHT) Size the output with specific dimensions. If the size is -k, --scale=(FACTOR) Set the output scale FACTOR. This is a distance identical with 100 points (1 default grid spacing) in gschem(1) coordinate space. It is used to size the output when nei‐ ther --paper nor --size are given, and defaults to 100 mil. -m, --margins=(auto | TOP[:LEFT[:BOTTOM[:RIGHT]]]) Set the widths of the margins to be used. If `auto' mar‐ gins are specified, a sensible default value will be cho‐ sen. Up to four margin widths can be provided. If one is provided, it will be used on all four sides. If two are provided, the first will be used for the top/bottom and the second for the left/right. If three are pro‐ vided, the first will be used for the top, the second for left/right, and the third for the bottom. -a, --align=(auto | HALIGN:VALIGN) Set how the drawing is aligned within the page. HALIGN controls the horizontal alignment, and VALIGN the verti‐ cal. Each alignment value should be in the range 0.0 to 1.0. The `auto' alignment is equivalent to a value of `0.5:0.5', i.e. centered. -d, --dpi=DPI Set the number of pixels per inch used when generating PNG output. -c, --color Enable colour output. --no-color Disable color output. -F, --font=FONT-FAMILY Set the font to be used for drawing text. -- Treat all remaining arguments as schematic or symbol filenames. Use this if you have a schematic or symbol filename which begins with `-'. The --size, --margins, or --scale options described above accept values using units of `mm', `cm', `in', `pc', `px', or `pt'. If you do not provide a unit, points are assumed. N.b. that `px' are evaluated relative to the current --dpi setting. When using the --size, --margins, or --align options with multi‐ ple values, you may use `;', or ` ' as a separator between them instead of `:'. In such a case, remember to properly quote your arguments to avoid them to be interpreted by your shell. ACCESSING CONFIGURATION gaf config [OPTION] [GROUP KEY [VALUE]] gaf config is a basic utility for inspecting and modifying gEDA/gaf configuration stores. If a GROUP and KEY are specified, retrieves the value of that configuration parameter. If a VALUE is specified, sets the value of that parameter. The -p, -u and -s options can be used to select the configuration store affected (by default, the project configuration store for the current working directory). If no GROUP and KEY are provided, outputs the filename of the selected configuration store. -p, --project[=PATH] Select the project configuration store of the project located in PATH. If no PATH is provided, selects the project in the current working directory. -u, --user Select the user configuration store. -s, --system Select the system configuration store. Depending on user permissions, the system configuration store may be read- only. SCHEME PROCESSING gaf shell [OPTION ...] gaf shell provides a Scheme Read-Eval-Print Loop (REPL) for automating processing of schematic and symbol files. It is designed to be used with the gEDA Scheme API. -s FILE Evaluate Scheme source code from FILE, and exit. -c EXPR Evaluate the Scheme expression EXPR, and exit. -- Stop scanning arguments; run interactively. -L DIRECTORY Prepend DIRECTORY to the list of directories to be searched for Scheme files. -l FILE Evaluate Scheme source code from FILE. The -s, -c and -- switches stop argument processing and pass all the remaining arguments as the value of `(command-line)'. ENVIRONMENT GEDADATA specifies the search directory for Scheme and rc files. The default is `${prefix}/share/gEDA'. GEDADATARC specifies the search directory for rc files. The default is `$GEDADATA'. AUTHORS See the `AUTHORS' file included with this program.
