FNC(1) General Commands Manual FNC(1) NAME fnc -- interactive text-based user interface for Fossil repositories SYNOPSIS fnc [-z] [-R repository] command [arg ...] fnc [-hv] fnc path fnc blame [-Chr] [-c commit] [-l lineno] [-n n] path fnc branch [-Cchopr] [-a date] [-b date] [-s order] [glob] fnc config [-hl] [-u option] [option [value]] fnc diff [-bCDhiloPqsWw] [-x n] [artifact1 [artifact2]] [path ...] fnc stash [-ChP] [-x n] [(get|pop) [id]] fnc timeline [-Ch] [-b branch] [-c commit] [-f glob] [-n n] [-T tag] [-t type] [-u user] [path] fnc tree [-Ch] [-c commit] [path] DESCRIPTION fnc is an interactive text-based user interface for exploring fossil(1) repositories, and managing local changes in a Fossil work tree. To facilitate navigation and display repository data, fnc supports mul- tiple views: Timeline Display commits from the repository's history in chronologi- cally descending order. If no command or only a path is speci- fied, fnc will default to displaying this view. Diff Display changes introduced in the specified commit, between two repository artifacts, or local changes in the work tree. Tree Display navigable tree reflecting the repository state as at the specified commit. Blame Display and annotate each line in the given file with the hy- perlinked commit in which the line was last modified. Branch Display navigable list of all repository branches. fnc provides both global and command-specific options, and runtime key bindings. Global options are as follows: -h, --help Display program help and usage information then exit. -R, --repo path Use the fossil(1) repository at the specified path for the current fnc invocation. -v, --version Display program version then exit. -z, --utc Display dates and timestamps in Coordinated Universal Time (UTC) rather than local time. This can also be configured with the FNC_UTC option (see "ENVIRONMENT" for details). Global key bindings are as follows: H, ?, F1 Display runtime help. C Toggle between coloured and monochromatic output. On supported terminals, fnc will default to displaying all views in colour. Colours can be customised using the config command or environ- ment variables (see "ENVIRONMENT" for details). Tab Switch focus between open views. f Toggle between fullscreen and splitscreen mode. By default, fnc will open child views in a vertical split if the terminal window is >= 120 columns wide. Set FNC_VIEW_SPLIT_MODE as doc- umented in the "ENVIRONMENT" section to change this behaviour. s Switch between horizontal and vertical splitscreen layout, and render all active views in the new layout. If the terminal is not wide enough when switching to a vertical split, views will render in fullscreen. ( When in a splitscreen view, decrease the size of the active split. ) When in a splitscreen view, increase the size of the active split. G, End Scroll to the last line in the view. gg, Home Scroll to the first line in the view. Q Quit fnc. q Quit the active view. Commands available to fnc are as follows: config [-hl] [-u option | option [value]] (aliases: conf, set) Retrieve the current or set a new value for option in the lo- cal repository. When specified, value will become the new value for option, otherwise fnc will display the current value of option. With no arguments, fnc config will list all user- defined options; see "ENVIRONMENT" for a detailed list of all available options and their default values. During initialisation, if no value is defined for a given op- tion in the local repository, environment variables will be searched. If still not found, fnc will fallback to default values. Unless the global -R option is used to specify a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. Options for fnc config are as follows: -h, --help Display config command help and usage information then exit. -l, --ls List all available options. -u, --unset option Clear the specified option. stash [-ChP] [-x n] [(get|pop) [id]] (aliases: save, sta) When run with neither the get nor pop subcommands, fnc stash will interactively iterate over each hunk comprising the diff of local changes in the work tree, and prompt the user to ei- ther stash or keep the current hunk. Valid answers are as follows: b scroll back^ m show more of the current hunk^ y yes, stash the current hunk n no, do not stash the current hunk a yes, stash this hunk and all remaining hunks in the current file k no, do not stash this hunk nor any remaining hunks in the current file A yes, stash this hunk and all remaining hunks in the diff K no, do not stash this hunk nor any remaining hunks in the diff Q abort the stash operation and discard any previous selections ? display help dialog ^Conditionally available when the current hunk occupies multi- ple pages. When all hunks have been selected, fnc will prompt the user to enter a stash message. If not provided, a default message of "fnc stash HASH-PREFIX", where "HASH-PREFIX" is an abbreviated SHA hash of the current checkout, will be used. At any time prior to the final hunk being selected (i.e., before being prompted for the stash message), the operation can be aborted by either answering "Q" at the prompt or opening the help dia- log and entering the Q key binding. This will discard any previous selections and leave the work tree unchanged. Available subcommands for fnc stash are as follows: get [id] (aliases: apply) Retrieve the stash changeset corresponding to the specified id and apply it to the current checkout. If id is omitted, the most recent stash entry will be applied. pop [id] Like get, but also remove the changeset from the stash cache. Options only apply to fnc stash (i.e., neither the get nor pop subcommands) and are as follows: -C, --no-colour Disable coloured output, which is enabled by default on supported terminals. -h, --help Display stash command help and usage information then exit. -P, --no-prototype Do not display the enclosing function or scope in the hunk header. The heuristic used to determine the en- closing scope will produce reliable results for all C- like languages (e.g., C/C++, Java, Python, JavaScript); however, Lisps and non-source code (e.g., make(1), Markdown, reStructuredText) will return mean- ingless results. -x, --context n Set n context lines to be shown in the interactive stash diff display such that 0 <= n <= 64. Illegal values are a no-op (default: 5). timeline [-Chz] [-b branch] [-c commit] [-f glob] [-n n] [-T tag] [-t type] [-u user] [path] (aliases: log, tl) Display repository history with a chronological log of all commits. If path is specified, only show commits that modi- fied the file(s) at this path. The path may be absolute, rel- ative to the current working directory, or relative to the repository root. Unless the global -R option is used to specify a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. If invoked in a work tree, the log entry of the commit on which the checkout is based will be prefixed with one of the following annotations: @ work tree of the checked-out commit contains no local changes ~ work tree of the checked-out commit contains local changes This command will be executed by default if fnc is invoked without an explicit command. Options for fnc timeline are as follows: -b, --branch branch Display commits on the specified branch. The expected argument is a glob of the symbolic branch name, with the most recent branch to match being selected. Pat- tern matching is case-insensitive unless branch has at least one uppercase character, which will make the search case-sensitive. By default, fnc will display all commits irrespective of the branch on which they reside. -C, --no-colour Disable coloured timeline, which is enabled by default on supported terminals. If this option is not used, colour can be toggled with the c timeline view key binding as documented below. User-defined colours are also supported (see "ENVIRONMENT" for details). -c, --commit commit Start timeline traversal from the specified commit. The expected argument is either a symbolic reference (e.g., branch name, tag), or (a unique abbreviated prefix of) a valid commit SHA1 or SHA3 hash, or an ISO 8601 formatted date. When this option is not used, fnc will begin traversing history from the latest com- mit. For a complete list of valid arguments this op- tion accepts, see Fossil's Check-in Names: https://fossil- scm.org/home/doc/trunk/www/checkin_names.wiki. -f, --filter glob Filter timeline by commits containing glob in any of the commit comment, user, or branch fields. Pattern matching is case-insensitive unless glob has at least one uppercase character, which will make the search case-sensitive. Filtering can also be performed at runtime with the F timeline view key binding as docu- mented below. -h, --help Display timeline command help and usage information then exit. -n, --limit n Limit timeline to the latest n commits. By default, fnc will load the entire repository history. Negative values are a no-op. -T, --tag tag Only display commits with T cards containing tag. The expected argument is a glob of a commit manifest's T card argument, with the most recent tag to match being selected. Pattern matching is case-insensitive unless tag has at least one uppercase character, which will make the search case-sensitive. By default, fnc will display all commits irrespective of which T cards are attached to the commit manifest. -t, --type type Only display type commits. Valid type values are as follows: ci check-in w wiki t ticket e technote f forum post g tag artifact By default, fnc will load all commits irrespective of type. This is a repeatable flag (e.g., fnc timeline -t e -t t). -u, --username user Only display commits authored by user. The search is case-insensitive by default unless user contains at least one uppercase character, which will make the search case-sensitive. Key bindings for fnc timeline are as follows: Arrow-down, j, >, . Move selection cursor down the timeline. Arrow-up, k, <, , Move selection cursor up the timeline. Arrow-right, l Scroll view to the right in the buffer. Comment field contents move left on the screen. Arrow-left, h Scroll view to the left in the buffer. Comment field contents move right on the screen. $ Scroll view to the rightmost position. This corre- sponds to the end of the longest log message summary line on the page. 0 Scroll view left to the start of the line. C-f, Page-down Scroll timeline view one page downwards in the buffer. C-b, Page-up Scroll timeline view one page upwards in the buffer. C-d Scroll timeline view half of one page downwards in the buffer. C-u Scroll timeline view half of one page upwards in the buffer. Enter Open a diff view displaying the changeset of the cur- rently selected commit. Space Tag or untag the currently selected commit as the base commit for the next tagged commit to be diffed against. If another commit is already tagged, open a diff view showing the changes between it and the cur- rently selected commit. b Open and populate a branch view with all repository branches. One of the listed branches can be selected to display a new timeline view of its commit history. D Diff local changes on disk in the current work tree against the currently selected commit. F Prompt to enter a search term to filter a new timeline view that displays commits with comment, user, or branch fields that match the entered pattern. t Open a tree view displaying the tree of the repository corresponding to the currently selected commit. / Prompt to enter a search term to begin searching for commits matching the pattern provided. The search term is an extended regular expression that is matched against the comment, author username, branch, and SHA1 or SHA3 hash of each commit in the repository. See re_format(7) for regular expression syntax. n Find the next commit that matches the current search term. The search will continue until either a match is found or the earliest commit on the timeline is consumed. N Find the previous commit that matches the current search term. The search will continue until either a match is found or the latest commit on the timeline is consumed. Backspace Cancel the current search or timeline traversal in progress (i.e., operations executed with / or G/End). diff [-bCDhiloPqsWw] [-x n] [artifact1 [artifact2]] [path ...] (alias: di) Display the differences between two repository artifacts, or between the local changes in the work tree and a given commit. If invoked in a work tree with no artifact arguments speci- fied, fnc will show the differences between the local changes in the work tree and the commit on which the current checkout is based. If invoked in a work tree and only artifact1 is specified, fnc will show the differences between the local changes in the work tree and the commit referenced by artifact1. When artifact1 and artifact2 are specified, the differences between these two versions will be displayed. Both artifact arguments must resolve to the same type (i.e., commits or blobs), and are expected to be either: symbolic references (e.g., branch names, tags); a commit or blob SHA1 or SHA3 (unique abbreviated) hash; or an ISO 8601 formatted date. If one or more path arguments are supplied, fnc will filter diffs so that only changes involving the file(s) in the named paths are displayed. Paths may be absolute, relative to the current working directory, or relative to the repository root. When invoked outside a work tree with the global -R option or requesting the differences between blobs, both artifact argu- ments must be specified; in the latter case, any trailing ar- guments are invalid and will be ignored. Unless the global -R option is used to specify a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. Options for fnc diff are as follows: -b, --brief Omit all changes. Show the file index and hash lines only. -C, --no-colour Disable coloured diff output, which is enabled by de- fault on supported terminals. If this option is not used, colour can be toggled with the c diff view key binding as documented below. User-defined colours are also supported (see "ENVIRONMENT" for details). -D, --min-diffstat Show minimal diffstat instead of the more verbose plot bar histogram. -h, --help Display diff command help and usage information then exit. -i, --invert Invert the differences between artifacts. -l, --line-numbers Display actual file line numbers in diff output. -o, --no-curses Do not initialise curses to render the diff view. Write the diff directly to the standard output. -P, --no-prototype Do not display the enclosing function or scope in the hunk header. The heuristic used to determine the en- closing scope will produce reliable results for all C- like languages (e.g., C/C++, Java, Python, JavaScript); however, Lisps and non-source code (e.g., make(1), Markdown, reStructuredText) will return mean- ingless results. This option is mutually exclusive with -l and -s, which produce incompatible hunk head- ers. -q, --quiet Do not output complete content of newly added or deleted files, which are displayed by default. Only show the file index and hash lines. -s, --sbs Display a side-by-side formatted diff. This option is mutually exclusive with -l. -W, --whitespace-eol Ignore end-of-line whitespace-only changes. -w, --whitespace Ignore whitespace-only changes. -x, --context n Set n context lines to be shown in the diff such that 0 <= n <= 64. Illegal values are a no-op (default: 5). All the above options (except -h and -o) can be made persis- tent as global or repository options via the FNC_DIFF_FLAGS option (see "ENVIRONMENT" for details). Key bindings for fnc diff are as follows: Arrow-down, j Scroll view one line downwards in the buffer. Diff output moves upwards on the screen. Arrow-up, k Scroll view one line upwards in the buffer. Diff out- put moves downwards on the screen. Arrow-right, l Scroll view to the right in the buffer. Diff output moves left on the screen. Arrow-left, h Scroll view to the left in the buffer. Diff output moves right on the screen. $ Scroll view to the rightmost position. This corre- sponds to the end of the longest line on the page. 0 Scroll view left to the start of the line. C-e Move the selection cursor down one line. C-y Move the selection cursor up one line. C-f, Page-down, Space Scroll diff view one page downwards in the buffer. C-b, Page-up Scroll diff view one page upwards in the buffer. C-d Scroll diff view half of one page downwards in the buffer. C-u Scroll diff view half of one page upwards in the buffer. C-k, K, <, , If the diff view is derived from the timeline view, move up to the previous (i.e., newer) commit and dis- play its diff. If derived from the blame view, move up to the previous line in the annotated file and dis- play the corresponding diff. C-j, J, >, . If the diff view is derived from the timeline view, move down the timeline to the next (i.e., older) com- mit and display its diff. If derived from the blame view, move down to the next line in the annotated file and display the corresponding diff. C-p Navigate to the previous file in the diff. C-n Navigate to the next file in the diff. [ Navigate to the previous hunk in the diff. ] Navigate to the next hunk in the diff. -, _ Decrease the number of context lines in the diff. =, + Increase the number of context lines in the diff. # Toggle the display of diff view (not actual file) line numbers. @ Open prompt to enter a line number and navigate to that line in the view. B Toggle brief diff mode by only displaying file index and hash lines. b Open and populate the branch view with all repository branches. D Toggle between minimal and histogram diffstat. i Toggle inversion of diff output. L Toggle file line number formatted diff. P Write the currently viewed diff to a file on disk. fnc will prompt the user for a path, which can be ab- solute or relative, that points to a location in ei- ther the current work tree or the tmp directory. If no path is input and the return key is entered, the diff will be written to the current working directory using the first ten characters of the current artifact hash as the filename with a ".diff" extension (e.g., 2870235eef.diff). If the path already exists, it will be overwritten. p In the diff hunk header, toggle display of which func- tion or scope each change is in; for example: @@ -2360,10 +2361,11 @@ draw_commits(struct fnc_view *view) S Toggle display of a side-by-side formatted diff. v Toggle verbosity of diff output. By default, fnc will display the entire content of newly added or deleted files. W Toggle whether end-of-line whitespace changes are ig- nored when comparing lines in the diff. w Toggle whether whitespace-only changes are ignored when comparing lines in the diff. / Prompt to enter a search term to begin searching the diff output for lines matching the pattern provided. The search term is an extended regular expression, which is documented in re_format(7). n Find the next line that matches the current search term. N Find the previous line that matches the current search term. tree [-Ch] [-c commit] [path] (aliases: dir, tr) Display a navigable tree of the repository. If a path is specified, display the corresponding subtree, otherwise display the root of the tree. The path may be ab- solute, relative to the current working directory, or relative to the repository root. With no options passed, the tree will reflect the state of the latest commit on trunk. Unless the global -R option is used to specify a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. Tree nodes are lexicographically ordered and may be postfixed with an identifier corresponding to the mode of the file ob- ject on disk as returned by lstat(2): / directory * executable @ symbolic link Nodes representing symbolic links are further annotated with the path of the source file (e.g., symlink@ -> targetpath) Options for fnc tree are as follows: -C, --no-colour Disable coloured output, which is enabled by default on supported terminals. If this option is not used, colour can be toggled with the c tree view key binding as documented below. User-defined colours are also supported (see "ENVIRONMENT" for details). -c, --commit commit Display the repository tree corresponding to the checkin identified by commit. The expected argument is either a symbolic reference (e.g., branch name, tag), or (a unique abbreviated prefix of) a valid com- mit SHA1 or SHA3 hash, or an ISO 8601 formatted date. When this option is not used, fnc will display the tree of the latest commit. For a complete list of valid arguments this option accepts, see Fossil's Check-in Names: https://fossil- scm.org/home/doc/trunk/www/checkin_names.wiki. -h, --help Display tree command help and usage information then exit. Key bindings for fnc tree are as follows: Enter, Arrow-right, l Enter the currently selected directory, or open a blame view of the currently selected file. Backspace, Arrow-left, h Move up a level to the parent directory. This is a no-op when in the root tree. Arrow-down, j Move selection cursor one node down the tree. Arrow-up, k Move selection cursor one node up the tree. C-f, Page-down Scroll tree view one page downwards in the buffer. C-b, Page-up Scroll tree view one page upwards in the buffer. C-d Scroll tree view half of one page downwards in the buffer. C-u Scroll tree view half of one page upwards in the buffer. Home, gg Move selection cursor to the first node in the tree. End, G Move selection cursor to the last node in the tree. b Open and populate the branch view with all repository branches. d Toggle display of the last modified timestamp for each tree entry. i Toggle display of the hash ID for all file nodes in the tree. t Open the timeline view of the currently selected tree entry. This will display the log of all commits in- volving the tracked file(s) corresponding to the se- lected tree node. / Prompt to enter a search term to begin searching the tree for entries matching the entered pattern. The search term is an extended regular expression, as doc- umented in re_format(7), and is matched against the path of each tree node. n Find the next tree node that matches the current search pattern. N Find the previous tree node that matches the current search pattern. blame [-Chr] [-c commit] [-l lineno] [-n n] path (aliases: praise, bl) Show commit attribution history for each line of the file at the named path, which may be absolute, relative to the current working directory, or relative to the repository root. Unless the global -R option is used to specifiy a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. Options for fnc blame are as follows: -C, --no-colour Disable coloured output, which is enabled by default on supported terminals. If this option is not used, colour can be toggled with the c blame view key bind- ing as documented below. User-defined colours are also supported (see "ENVIRONMENT" for details). -c, --commit commit Start annotation of the tracked file from the speci- fied commit. The expected argument is either a sym- bolic reference (e.g., branch name, tag), or (a unique abbreviated prefix of) a valid commit SHA1 or SHA3 hash, or an ISO 8601 formatted date. When this option is not used, fnc will begin annotation from the latest commit. For a complete list of valid arguments this option accepts, see Fossil's Check-in Names: https://fossil- scm.org/home/doc/trunk/www/checkin_names.wiki. -h, --help Display blame command help and usage information then exit. -l, --line lineno Open the annotated file and navigate directly to lineno. -n, --limit n Limit depth of blame history to n commits or seconds. The latter is denoted by a postfixed 's' (e.g., 30s). With this option, fnc will traverse either as many commits as specified or as possible in the specified time limit. By default, fnc will traverse the entire historical record of the file, which can be expensive for large files that span many commits. Use this op- tion for a faster, more targeted annotation. -r, --reverse Reverse annotate the file starting from a historical commit and move forward in time so that instead of showing the most recent commit that changed each line, show the first commit that modified each line after the specified commit (requires -c). Key bindings for fnc blame are as follows: Arrow-down, j Move selection cursor down one line. Arrow-up, k Move selection cursor up one line. Arrow-right, l Scroll view to the right in the buffer. File contents move left on the screen. Arrow-left, h Scroll view to the left in the buffer. File contents move right on the screen. $ Scroll view to the rightmost position. This corre- sponds to the end of the longest line on the page. 0 Scroll the view left to the beginning of the line. C-f, Page-down Scroll blame view one page downwards in the buffer. C-b, Page-up Scroll blame view one page upwards in the buffer. C-d Scroll blame view half of one page downwards in the buffer. C-u Scroll blame view half of one page upwards in the buffer. Home, gg Move selection cursor to the first line in the file. End, G Move selection cursor to the last line in the file. Enter Open a diff view of the commit corresponding to the currently selected line. # Toggle display of file line numbers. @ Open prompt to enter a line number and navigate to that line in the file. P, Backspace Reload the previously blamed version of the file. c Blame the version of the file corresponding to the commit in the currently selected line. p Blame the version of the file corresponding to the parent of the commit in the currently selected line. b Open and populate a branch view with all repository branches. t Open a timeline view that begins traversing the time- line from the commit corresponding to the currently selected annotated line. / Prompt to enter a search term to begin searching the file for tokens matching the entered pattern. The search term is an extended regular expression, as doc- umented in re_format(7). N Find the previous token that matches the current search pattern. n Find the next token that matches the current search pattern. branch [-Cchopr] [-a date] [-b date] [-s order] [glob] (aliases: br, ref) Display navigable list of repository branches. If glob is specified, only display branches matching the pat- tern provided. Pattern matching is case-insensitive unless glob contains at least one uppercase character, which will make the search case-sensitive. Unless the global -R option is used to specify a fossil(1) repository, this command must be invoked from within a work tree; that is, fnc assumes a local checkout is open in or above the current working directory. Branches are lexicographically ordered by default, and are prefixed with an identifier corresponding to the branch state (i.e., open/closed). The current and private branches are further annotated with a postfixed identifier: +dev-foo open -rm-bar closed +trunk@ current +wip-baz* private All branches, irrespective of state or privacy, are displayed by default, but can be filtered based on several characteris- tics. Options for fnc branch are as follows: -a, --after date Display only those branches with activity after the specified date, which is expected to be either an ISO 8601 (e.g., 2020-10-10) or unambiguous DD/MM/YYYY or MM/DD/YYYY formatted date. -b, --before date Display only those branches with activity before the specified date, which is expected to be either an ISO 8601 (e.g., 2020-10-10) or unambiguous DD/MM/YYYY or MM/DD/YYYY formatted date. -C, --no-colour Disable coloured output, which is enabled by default on supported terminals. If this option is not used, colour can be toggled with the c branch view key bind- ing as documented below. User-defined colours are also supported (see "ENVIRONMENT" for details). -c, --closed Display only closed branches. -h, --help Display branch command help and usage information then exit. -o, --open Display only opened branches. -p, --no-private Do not show private branches, which are included in the list of displayed branches by default. -r, --reverse Reverse the order in which branches are displayed. -s, --sort order Sort branches by order. Valid order values are as follows: mru most recently used state open/closed state Branches are sorted in lexicographical order by de- fault. Key bindings for fnc branch are as follows: Arrow-down, j Move selection cursor down one branch. Arrow-up, k Move selection cursor up one branch. C-f, Page-down Scroll branch view one page downwards in the buffer. C-b, Page-up Scroll branch view one page upwards in the buffer. C-d Scroll branch view half of one page downwards in the buffer. C-u Scroll branch view half of one page upwards in the buffer. Home, gg Move selection cursor to the first branch in the list. End, G Move selection cursor to the last branch in the list. Enter, Space Display a timeline view of the currently selected branch. d Toggle display of the date on which the branch last received changes. i Toggle display of the SHA1 or SHA3 hash that identi- fies each branch, which is the commit hash of the branch tip. o Toggle sort order of currently displayed branches. fnc will cycle from lexicographical order to most re- cently used and then open/closed state. t Open a tree view of the currently selected branch. R, C-l Reload the view with all repository branches, irre- spective of which options were used in this fnc branch invocation. / Prompt to enter a search term to begin searching the list for branches matching the entered pattern. The search term is an extended regular expression, as doc- umented in re_format(7). n Find the next branch that matches the current search pattern. N Find the previous branch that matches the current search pattern. ENVIRONMENT When the terminal window is >= 120 columns wide, fnc will display child views in a vertical split at least 80 columns wide, otherwise a fullscreen will be used. To open child views in a horizontal split in- stead, configure the following option as either an exported environment variable or with fnc config as documented above. FNC_VIEW_SPLIT_MODE Open child views in a horizontal or vertical split. Value can be either "horizontal" or "vertical" (default: vertical). fnc displays all dates and timestamps in local time unless the global -z option is specified, in which case all dates and timestamps are in Coordinated Universal Time (UTC). This can be made persistent without using the global -z option by setting the following option as either an exported environment variable or with fnc config as documented above. FNC_UTC If set to a non-empty value, display dates and timestamps in Coordinated Universal Time (UTC). Similarly, diff options can be persistently applied to all diff views whether directly accessed with fnc diff or as a child view of the timeline or blame views by configuring the following options: FNC_DIFF_FLAGS String containing any or all of the available short form diff boolean flag options documented above ex- cept for the -h and -o options (i.e., bCDilPqsWw). If mutually exclusive options "l" and "s" are both specified, whichever is last will take precedence; for example, "lqs" will display side-by-side format- ted diffs (default: ""). FNC_DIFF_CONTEXT Numeric value as per the above documented -x option (i.e., 0 <= n <= 64) specifying the number of context lines (default: 5). Any options passed to fnc diff will override the above settings. fnc displays coloured output by default in supported terminals. Each colour object identified below can be defined by either exporting envi- ronment variables (e.g., export FNC_COLOUR_COMMIT=red), or with fnc config as documented above. At startup, fnc will search for user-de- fined colours in the following order: 1. repository options repo.fossil 2. environment variables shell If none are found, the default colour scheme will be displayed. This enables setting per-project colours to visually distinguish the current repository being viewed, and globally changing the colour scheme for all repositories with no local options configured. Except where docu- mented below, colours supported in fnc are: "black" "green" "blue" "cyan" "red" "yellow" "magenta" "default" Where "default" is the current foreground (i.e., text) colour in the terminal. User-definable colour objects displayed in various fnc views are as follows: FNC_COLOUR_COMMIT The commit hash ID field displayed in the timeline, diff, tree, and blame views (default: "green"). FNC_COLOUR_USER The username field displayed in the timeline and diff views (default: "cyan"). FNC_COLOUR_DATE The date field displayed in the timeline and diff views (default: "yellow"). FNC_COLOUR_DIFF_MINUS Removed lines displayed in the diff view (default: "magenta"). FNC_COLOUR_DIFF_PLUS Added lines displayed in the diff view (default: "cyan"). FNC_COLOUR_DIFF_HUNK Hunk header lines (e.g., @@ -732,34 +747,40 @@) displayed in the diff view (default: "yellow"). FNC_COLOUR_DIFF_META Metadata displayed in the diff view (default: "green"). FNC_COLOUR_DIFF_TAGS The tag field displayed in the diff view (default: "magenta"). FNC_COLOUR_DIFF_SBS_EDIT Changed (i.e., not added or removed) lines in the diff view when displaying side-by- side diffs (default: "red"). FNC_COLOUR_TREE_DIR Directory entries displayed in the tree view (default: "cyan"). FNC_COLOUR_TREE_EXEC Executable file entries displayed in the tree view (default: "green"). FNC_COLOUR_TREE_LINK Symbolic link entries displayed in the tree view (default: "magenta"). FNC_COLOUR_BRANCH_OPEN Open branches displayed in the branch view (default: "cyan"). FNC_COLOUR_BRANCH_CLOSED Closed branches displayed in the branch view (default: "magenta"). FNC_COLOUR_BRANCH_CURRENT The branch corresponding to the current checkout displayed in the branch view (default: "green"). FNC_COLOUR_BRANCH_PRIVATE Private branches displayed in the branch view (default: "yellow"). FNC_COLOUR_HL_LINE Selected line highlight in the diff view. Value can be one of auto or mono. The for- mer will invert the foreground colour of the selected line, while the latter will use a monochromatic highlight (default: "auto"). FNC_COLOUR_HL_SEARCH Search term highlight in the blame and diff views (default: "yellow"). To clear environment variables, invoke the shell builtin unset; for ex- ample, "unset FNC_DIFF_CONTEXT". As documented above, local options can be unset with fnc config -u option. fnc displays best with UTF-8, and will detect whether UTF-8 is enabled to determine which characters to draw in certain views. If UTF-8 is supported by your terminal but is currently disabled, it can be enabled with "export LC_CTYPE=en_US.UTF-8"; If not available, fnc will revert to ASCII. Relatedly, some fonts may render certain characters poorly in the help screen as they lack the requisite glyphs; Monospace Regular, JetBrains Mono, and Menlo are known to render all characters well. EXIT STATUS The fnc utility exits 0 on success, and >0 if an error occurs.
