# Documentation

progname :: ProgramName #

The name of this program's executable.

prognameandversion :: String #

Generate the version string for this program. The template haskell call is here rather than in Hledger.Cli.Version to avoid wasteful recompilation.

# cmdargs flags & modes

inputflags :: [Flag RawOpts] #

Common input-related flags: --file, --rules, --conf, --alias...

reportflags :: [Flag RawOpts] #

Common report-related flags: --period, --cost, etc.

helpflags :: [Flag RawOpts] #

terminalflags :: [Flag RawOpts] #

helpflagstitle :: String #

flattreeflags :: Bool -> [Flag RawOpts] #

Flags for selecting flat/tree mode, used for reports organised by account. With a True argument, shows some extra help about inclusive/exclusive amounts.

confflags :: [Flag RawOpts] #

hledger CLI's --conf/--no-conf flags.

hiddenflags :: [Flag RawOpts] #

hiddenflagsformainmode :: [Flag RawOpts] #

Common legacy flags that are accepted but not shown in --help, when running the main mode.

outputFormatFlag :: [String] -> Flag RawOpts #

Common output-related flags: --output-file, --output-format...

outputFileFlag :: Flag RawOpts #

generalflagsgroup1 :: (String, [Flag RawOpts]) #

generalflagsgroup2 :: (String, [Flag RawOpts]) #

generalflagsgroup3 :: (String, [Flag RawOpts]) #

mkgeneralflagsgroups1 :: [Flag RawOpts] -> [(String, [Flag RawOpts])] #

mkgeneralflagsgroups2 :: [Flag RawOpts] -> [(String, [Flag RawOpts])] #

mkgeneralflagsgroups3 :: [Flag RawOpts] -> [(String, [Flag RawOpts])] #

cligeneralflagsgroups1 :: [(String, [Flag RawOpts])] #

cligeneralflagsgroups2 :: [(String, [Flag RawOpts])] #

cligeneralflagsgroups3 :: [(String, [Flag RawOpts])] #

defMode :: Mode RawOpts #

An empty cmdargs mode to use as a template. Modes describe the top-level command, ie the program, or a subcommand, telling cmdargs how to parse a command line and how to generate the command's usage text.

defCommandMode :: [Name] -> Mode RawOpts #

A cmdargs mode suitable for a hledger built-in command with the given names (primary name + optional aliases). The usage message shows [QUERY] as argument.

addonCommandMode :: Name -> Mode RawOpts #

A cmdargs mode representing the hledger add-on command with the given name, providing hledger's common inputreportinghelp flags. Just used when invoking addons.

hledgerCommandMode :: CommandHelpStr -> [Flag RawOpts] -> [(String, [Flag RawOpts])] -> [Flag RawOpts] -> ([Arg RawOpts], Maybe (Arg RawOpts)) -> Mode RawOpts #

Build a cmdarg mode for a hledger command, from a help template and flag/argument specifications. Reduces boilerplate a little, though the complicated cmdargs flag and argument specs are still required.

argsFlag :: FlagHelp -> Arg RawOpts #

showModeUsage :: Mode a -> String #

Get a mode's usage message as a nicely wrapped string.

withAliases :: String -> [String] -> String #

Add command aliases to the command's help string.

likelyExecutablesInPath :: IO [String] #

Get all sorted unique filenames in the current user's PATH. We do not currently filter out non-file objects or files without execute permission.

hledgerExecutablesInPath :: IO [String] #

Get the sorted unique filenames of all hledger-* executables in the current user's PATH. These are files in any of the PATH directories, named hledger-*, with either no extension (and no periods in the name) or one of the addonExtensions. We do not currently filter out non-file objects or files without execute permission.

# CLI options

data CliOpts #

Command line options, used in the `hledger` package and above. This is the "opts" used throughout hledger CLI code. representing the options and arguments that were provided at startup on the command-line.

defcliopts :: CliOpts #

getHledgerCliOpts :: Mode RawOpts -> IO CliOpts #

getHledgerCliOpts' :: Mode RawOpts -> [String] -> IO CliOpts #

A helper for addon commands: this parses options and arguments from the current command line using the given hledger-style cmdargs mode, and returns a CliOpts. Or, with --help or -h present, it prints long or short help, and exits the program. When --debug is present, also prints some debug output. Note this is not used by the main hledger executable.

The help texts are generated from the mode. Long help includes the full usage description generated by cmdargs (including all supported options), framed by whatever pre- and postamble text the mode specifies. It's intended that this forms a complete help document or manual.

Short help is a truncated version of the above: the preamble and the first part of the usage, up to the first line containing "flags:" (normally this marks the start of the common hledger flags); plus a mention of --help and the (presumed supported) common hledger options not displayed.

Tips: Empty lines in the pre/postamble are removed by cmdargs; add a space character to preserve them.

rawOptsToCliOpts :: RawOpts -> IO CliOpts #

Parse raw option string values to the desired final data types. Any relative smart dates will be converted to fixed dates based on today's date. Parsing failures will raise an error. Also records the terminal width, if supported.

outputFormats :: [String] #

All the output formats known by any command, for outputFormatFromOpts. To automatically infer it from -o/--output-file, it needs to be listed here.

defaultOutputFormat :: String #

type CommandHelpStr = String #

A command's name, optional official abbreviation, and help preamble & postamble, as a specially formatted single string. Used to generate the CLI help, and also the command's doc in the hledger manual. See parseCommandHelp for the format.

parseCommandHelp :: CommandHelpStr -> Maybe CommandHelp #

Parse a command's embedded help text (`Somecommand.txt`). That text is generated by `Shake cmdhelp` from the command's doc source (`Somecommand.md`). `Somecommand.md` should be formatted as follows:

- First line: the command name, as a markdown heading.
- Optional third line: the command's official abbreviated name, parenthesised.
- From third or fifth line to a ````flags` line: the command help preamble. Usually one sentence or paragraph; any blank lines will not be rendered.
- A fenced code block beginning with ````flags`, containing a `Flags:` line, followed by a snapshot of the command-specific flags help as generated by cmdargs or "none" if there are no command-specific flags. This should contain no blank lines (no extra newlines in the cmdargs command mode help strings). This is shown as-is in manuals, and regenerated at runtime for --help output.
- Any remaining lines: the command help postamble.

(Note the difference between `Somecommand.md`, which is the markdown source file, and `Somecommand.txt`, which is the plain text file generated by `Shake cmdhelp`, which this function parses.)

# CLI option accessors

These do the extra processing required for some options.

journalFilePathFromOpts :: CliOpts -> IO (NonEmpty String) #

Get the (tilde-expanded, absolute) journal file path from 1. options, 2. an environment variable, or 3. the default. Actually, returns one or more file paths. There will be more than one if multiple -f options were provided. File paths can have a READER: prefix naming a reader/data format.

rulesFilePathFromOpts :: CliOpts -> IO (Maybe FilePath) #

Get the (tilde-expanded) rules file path from options, if any.

outputFileFromOpts :: CliOpts -> IO (Maybe FilePath) #

Get the expanded, absolute output file path specified by an -o/--output-file options, or nothing, meaning stdout.

outputFormatFromOpts :: CliOpts -> String #

Get the output format from the --output-format option, otherwise from a recognised file extension in the --output-file option, otherwise the default (txt).

defaultWidth :: Int #

Default width for hledger console output, when not otherwise specified.

replaceNumericFlags :: [String] -> [String] #

Replace any numeric flags (eg -2) with their long form (--depth 2), as I'm guessing cmdargs doesn't support this directly.

ensureDebugFlagHasVal :: [String] -> [String] #

For register:

registerWidthsFromOpts :: CliOpts -> (Int, Maybe Int) #

Get the width in characters to use for the register command's console output, and also the description column width if specified (following the main width, comma-separated). The widths will be as follows: `no --width flag - overall width is the available width (COLUMNS, or posix terminal width, or 80); description width is unspecified (auto) --width W - overall width is W, description width is auto --width W,D - overall width is W, description width is D` Will raise a parse error for a malformed --width argument.

# Other utils

hledgerAddons :: IO [String] #

Get the sorted unique canonical names of hledger addon commands found in the current user's PATH. These are used in command line parsing and to display the commands list.

Canonical addon names are the filenames of hledger-* executables in PATH, without the "hledger-" prefix, and without the file extension except when it's needed for disambiguation (see below).

When there are exactly two versions of an executable (same base name, different extensions) that look like a source and compiled pair (one has .exe, .com, or no extension), the source version will be excluded (even if it happens to be newer). When there are three or more versions (or two versions that don't look like a source/compiled pair), they are all included, with file extensions intact.

topicForMode :: Mode a -> Topic #

Get the most appropriate documentation topic for a mode. Currently, that is either the hledger, hledger-ui or hledger-web manual.
