Functions handling the `opam config` subcommand and configuration actions
val env :
'a OpamStateTypes.global_state ->
OpamTypes.switch ->
?set_opamroot:bool ->
?set_opamswitch:bool ->
csh:bool ->
sexp:bool ->
fish:bool ->
pwsh:bool ->
cmd:bool ->
inplace_path:bool ->
unit
Display the current environment. Booleans csh, sexp and fish set an alternative output (unspecified if more than one is true, sh-style by default). inplace_path
changes how the PATH variable is updated when there is already an opam entry: either at the same rank, or pushed in front.
val ensure_env : 'a OpamStateTypes.global_state -> OpamTypes.switch -> unit
Ensures that the environment file exists in the given switch, regenerating it, if necessary.
val print_eval_env :
csh:bool ->
sexp:bool ->
fish:bool ->
pwsh:bool ->
cmd:bool ->
OpamTypes.env ->
unit
Like env
but allows one to specify the precise env to print rather than compute it from a switch state
val list : 'a OpamStateTypes.switch_state -> OpamTypes.name list -> unit
Display the content of all available packages variables
val subst : 'a OpamStateTypes.global_state -> OpamTypes.basename list -> unit
Substitute files
val expand : 'a OpamStateTypes.global_state -> string -> unit
Prints expansion of variables in string
val exec :
[< OpamStateTypes.unlocked ] OpamStateTypes.global_state ->
set_opamroot:bool ->
set_opamswitch:bool ->
inplace_path:bool ->
no_switch:bool ->
string list ->
unit
Execute a command in a subshell, after variable expansion
Functions handling `opam var` and `opam option` command
Given an `opam option` field or field-value argument, detect the scope, switch, global or nonexistent field (cf. OpamCommands.Var_Option_Common.var_option
)
val parse_update : string -> string * update_op
Parse an update operation. String is of the form var[(+=|-=|=)[value]]
. If 'value' is absent, it is a revert operation. Raise Invalid_argument
if the string is malformed
val parse_whole : string -> string * whole_op
As parse_update
but parse only overwrites and reverts. String is of the form var=[value]
`. Raise Invalid_argument
if the string is malformed
val set_opt_global :
OpamStateTypes.rw OpamStateTypes.global_state ->
string ->
update_op ->
OpamStateTypes.rw OpamStateTypes.global_state
set_opt_global gt field value
updates global config field with update value in <opamroot>/config file. Modifiable fields are a subset of all defined fields in OpamFile.Config.t
. On revert, field is reverted to its initial value as defined in OpamInitDefaults.init_config
, to default value otherwise (OpamFile.Config.empty
). May raise OpamStd.Sys.Exit 2
.
val set_opt_switch :
'a OpamStateTypes.global_state ->
?st:OpamStateTypes.rw OpamStateTypes.switch_state ->
string ->
update_op ->
OpamStateTypes.rw OpamStateTypes.switch_state option
As set_opt_global
, set_opt_switch
updates switch config file in <opamroot>/<switch>/.opam-switch/switch-config. If switch state is given, uses its config and returns it with then new config. Otherwise, loads the raw switch state and returns None
. Raises OpamStd.Sys.Exit 50
(`Configuration_error
) if no switch is set
val set_var_global :
OpamStateTypes.rw OpamStateTypes.global_state ->
string ->
whole_op ->
OpamStateTypes.rw OpamStateTypes.global_state
set_var_global
and set_var_switch
update respectively `global-variables` field in global config and `variables` field in switch config, by appending the new variables to current set. If switch state is given, uses its config and returns it with then new config. Otherwise, loads the raw switch state and returns None
. Raises OpamStd.Sys.Exit 2
(`Bad_argument
) if field is not modifiable
val set_var_switch :
'a OpamStateTypes.global_state ->
?st:OpamStateTypes.rw OpamStateTypes.switch_state ->
string ->
whole_op ->
OpamStateTypes.rw OpamStateTypes.switch_state option
Raises OpamStd.Sys.Exit 50
(`Configuration_error
) if no switch is set
List switch and/or global fields/sections and their value. If switch state is given, uses its config, otherwise loads the raw switch state.
val options_list :
?st:OpamStateTypes.unlocked OpamStateTypes.switch_state ->
'a OpamStateTypes.global_state ->

val options_list_switch :
?st:OpamStateTypes.unlocked OpamStateTypes.switch_state ->
'a OpamStateTypes.global_state ->
unit
Raises OpamStd.Sys.Exit 50
(`Configuration_error
) if no switch is set
List switch and/or global variables and their value. If switch state is given, uses its config, otherwise loads the raw switch state.
val vars_list :
?st:'a OpamStateTypes.switch_state ->
'b OpamStateTypes.global_state ->
unit
val vars_list_global : 'a OpamStateTypes.global_state -> unit
val vars_list_switch :
?st:'a OpamStateTypes.switch_state ->
'b OpamStateTypes.global_state ->
unit
Raises OpamStd.Sys.Exit 50
(`Configuration_error
) if no switch is set
Display field
name and content in the global / switch configuration. If switch state is given, uses its config, otherwise loads the raw switch state.
val option_show_global : 'a OpamStateTypes.global_state -> string -> unit
val option_show_switch :
'a OpamStateTypes.global_state ->
?st:OpamStateTypes.unlocked OpamStateTypes.switch_state ->
string ->
unit
Raises OpamStd.Sys.Exit 50
(`Configuration_error
) if no switch is set
Display var
name and content in the global / switch configuration. Look first in the raw switch_state, if not found, uses the given switch state or loads one.
