charset=UTF-8 Content-Transfer-Encoding: 8bit This migration enables standard matrix operations (range slicing, arithmetic, broadcasting) on state variables in the exa backend by using p.x_m (a matrix of ExaModels.Var) instead of p.x (ExaModels.Variable). Changes: - Add x_m field to ParsingInfo struct - Initialize p.x_m in p_state! and p_state_exa! functions - Replace p.x with p.x_m in 13 locations across 4 functions: * p_constraint_exa!: boundary and path constraints (5 replacements) * p_dynamics_coord_exa!: state dynamics discretization (4 replacements) * p_lagrange_exa!: Lagrange cost function (2 replacements) * p_mayer_exa!: Mayer cost function (2 replacements) - Remove 3 useless substitution lines in p_constraint_exa! - Enable direct arithmetic operations: p.x_m[i, j+1] - p.x_m[i, j] The p.x_m matrix is defined as [x[i, j] for i ∈ 1:n, j ∈ 1:grid_size+1], providing more efficient access patterns for discretized optimal control.

Changes: 1. Removed p.x_m matrix wrapper from ParsingInfo struct 2. Reverted all p.x_m references back to p.x (ExaModels.Variable) - p.x properly handles symbolic indexing in ExaModels generators - p.x_m (plain Matrix) was causing ArgumentError with symbolic indices 3. Migrated from 1-based to 0-based grid indexing: - State/control variables: 0:grid_size (was 1:grid_size+1) - Initial conditions: index 0 (was 1) - Final conditions: index grid_size (was grid_size+1) - Dynamics constraints: 0:grid_size-1 (was 1:grid_size) - Path constraints: 0:grid_size (was 1:grid_size+1) - Lagrange cost integration: * Euler forward: 0:grid_size-1 (was 1:grid_size) * Euler implicit: 1:grid_size (was 2:grid_size+1) * Midpoint: 0:grid_size-1 (was 1:grid_size) * Trapeze: endpoints (0, grid_size), interior 1:grid_size-1 4. Documentation improvements in utils.jl for subs3 and subs4 Rationale: The p.x_m approach attempted to enable matrix operations but failed because generator variables in ExaModels become symbolic types (ParSource, Node2), which cannot index regular Julia arrays. Using p.x (ExaModels.Variable) throughout ensures proper symbolic indexing support. 0-based indexing provides cleaner semantics for discretization schemes, with grid points at times t0 + j*dt for j in 0:grid_size. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/onepass.jl | 63 ++++++++++++++++++++++++-------------------------- src/utils.jl | 4 ++-- 2 files changed, 32 insertions(+), 35 deletions(-) diff --git a/src/onepass.jl b/src/onepass.jl index 375063b..0f1f39f 100644 --- a/src/onepass.jl +++ b/src/onepass.jl @@ -121,7 +121,6 @@ $(TYPEDEF) t0::Union{Real,Symbol,Expr,Nothing} = nothing tf::Union{Real,Symbol,Expr,Nothing} = nothing x::Union{Symbol,Nothing} = nothing - x_m::Union{Symbol,Nothing} = nothing u::Union{Symbol,Nothing} = nothing dim_v::Union{Integer,Symbol,Expr,Nothing} = nothing dim_x::Union{Integer,Symbol,Expr,Nothing} = nothing @@ -537,7 +536,6 @@ function p_state!( x = xg end p.x = x - p.x_m = __symgen(Symbol(x, (:_m))) p.dim_x = n nn = n isa Int ? n : 9 for i in 1:nn @@ -575,9 +573,9 @@ function p_state_exa!(p, p_ocp, x, n, xx;

Enhanced subs2 function (utils.jl): - Added range indexing support: x[1:3] β†’ [y[k, j] for k ∈ 1:3] - Preserves scalar indexing behavior: x[i] β†’ y[i, j] - Added optional 'k' parameter for predictable symbol generation in tests - New pattern: :($xx[$rg]) when is_range(rg) generates comprehension - Existing pattern: :($xx[$i]) continues to work for scalars 2. Reorganized utility functions (onepass.jl β†’ utils.jl): - Moved __symgen() to utils.jl (needed by subs2 for range support) - Consolidated is_range() and as_range() at top of utils.jl - Better organization: all utility functions now in one place 3. Comprehensive test suite (test_utils.jl): - 18 tests for subs2 (up from 2 original tests) - Tests organized into 6 testsets: * Scalar indexing (backward compatibility - 4 tests) * Range indexing (new functionality - 5 tests) * Mixed scalar/range (1 test) * Nested/complex expressions (3 tests) * Edge cases (4 tests) * Backward compatibility verification (1 test) - All tests use explicit k parameter for exact equality assertions 4. Test configuration (runtests.jl): - Default to running only utils and utils_bis tests - Other tests disabled to speed up development iteration - Can still run all tests with: julia test/runtests.jl all Implementation details: - Range detection uses is_range() predicate (checks AbstractRange or i:j expr) - Comprehension variable k generated via __symgen() or passed explicitly - Backward compatible: existing code using scalar indices unchanged - Forward compatible: supports symbolic ranges (1:n, 2:2:grid_size, etc.) This enhancement enables tensor/matrix operations in the ExaModels backend by allowing range-based substitutions in symbolic expressions. --- src/onepass.jl | 13 ----- src/utils.jl | 61 ++++++++++++++---------- test/runtests.jl | 14 +++--- test/test_utils.jl | 116 ++++++++++++++++++++++++++++++++++++++++++--- 4 files changed, 153 insertions(+), 51 deletions(-) diff --git a/src/onepass.jl b/src/onepass.jl index 350341a..f02b8ec 100644 --- a/src/onepass.jl +++ b/src/onepass.jl @@ -96,19 +96,6 @@ function e_prefix!(p) return nothing end -# Utils - -""" -$(TYPEDSIGNATURES) - -Generate a fresh symbol by concatenating the given components and a -`gensym()` suffix. - -This is used throughout the parser to create unique internal names that -do not collide with user-defined identifiers. -""" -__symgen(s...) = Symbol(s..., gensym()) - """ $(TYPEDEF) diff --git a/src/utils.jl b/src/utils.jl index 684d378..6005f0c 100644 --- a/src/utils.jl +++ b/src/utils.jl @@ -4,6 +4,39 @@ """ $(TYPEDSIGNATURES) +Generate a fresh symbol by concatenating the given components and a +`gensym()` suffix. + +This is used throughout the parser to create unique internal names that +do not collide with user-defined identifiers. +""" +__symgen(s...) = Symbol(s..., gensym()) + +""" +$(TYPEDSIGNATURES) + +Return `true` if `x` represents a range. + +This predicate is specialised for `AbstractRange` values and for +expressions of the form `i:j` or `i:p:j`. +""" +is_range(x) = false +is_range(x::T) where {T<:AbstractRange} = true +is_range(x::Expr) = (x.head == :call) && (x.args[1] == :(:)) + +""" +$(TYPEDSIGNATURES) + +Return `x` itself if it is a range, or a one-element array `[x]`. + +This is a normalisation helper used when interpreting constraint +indices. +""" +as_range(x) = is_range(x) ? x : [x] + +""" +$(TYPEDSIGNATURES) + Expr iterator: apply `_Expr` to nodes and `f` to leaves of the AST. # Example @@ -81,12 +114,12 @@ julia> subs2(subs2(e, :x0, :x, 0), :xf, :x, :N) :(x0 * (2 * x[3, N]) - cos(xf) * (2 * x[2, 0])) ``` """ -function subs2(e, x, y, j) +function subs2(e, x, y, j;

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit reverts the dim parameter addition to subs2, as bare symbol expansion (x β†’ [y[k, j] for k ∈ 1:dim]) cannot be handled at the subs2 level. Changes: - src/onepass.jl: Removed dim parameter from all 14 subs2 calls - Lines 700-701: Boundary constraints (p_constraint_exa!) - Lines 800-801: Path constraints (p_constraint_exa!) - Lines 900-907: Dynamics discretization (p_dynamics_coord_exa!) - Lines 970-974: Lagrange cost (p_lagrange_exa!) - Lines 1033-1034: Mayer cost (p_mayer_exa!) - src/utils.jl: Updated subs2 docstring - Removed bare symbol pattern from documentation - Changed from 3 patterns to 2 patterns (scalar and range only) - Updated examples to show bare symbols are NOT substituted - Restored original signature: subs2(e, x, y, j; k = __symgen(:k)) - test/test_utils.jl: Updated all subs2 tests - Removed dim parameter from all 18 test calls - Updated Test 2 and Test 19 expectations (bare symbols NOT substituted) - Verified all range indexing tests still pass without dim parameter Rationale: Bare symbol expansion requires dimension information that is not available at the expression substitution level. This functionality will need to be implemented at a higher level in the parsing pipeline. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/onepass.jl | 28 ++++++++++++++-------------- src/utils.jl | 21 +++++++++------------ test/test_utils.jl | 46 +++++++++++++++++++++++----------------------- 3 files changed, 46 insertions(+), 49 deletions(-) diff --git a/src/onepass.jl b/src/onepass.jl index 95186da..f02b8ec 100644 --- a/src/onepass.jl +++ b/src/onepass.jl @@ -697,8 +697,8 @@ function p_constraint_exa!(p, p_ocp, e1, e2, e3, c_type, label) xf = __symgen(:xf) e2 = replace_call(e2, p.x, p.t0, x0) e2 = replace_call(e2, p.x, p.tf, xf) - e2 = subs2(e2, x0, p.x, 0, p.dim_x) - e2 = subs2(e2, xf, p.x, :grid_size, p.dim_x) + e2 = subs2(e2, x0, p.x, 0) + e2 = subs2(e2, xf, p.x, :grid_size) concat(code, :($pref.constraint($p_ocp, $e2; lcon=($e1), ucon=($e3)))) # debug: to vectorise end (:initial, rg) => begin @@ -797,8 +797,8 @@ function p_constraint_exa!(p, p_ocp, e1, e2, e3, c_type, label) ut = __symgen(:ut) e2 = replace_call(e2, [p.x, p.u], p.t, [xt, ut]) j = __symgen(:j) - e2 = subs2(e2, xt, p.x, j, p.dim_x) - e2 = subs2(e2, ut, p.u, j, p.dim_u) + e2 = subs2(e2, xt, p.x, j) + e2 = subs2(e2, ut, p.u, j) e2 = subs(e2, p.t, :($(p.t0) + $j * $(p.dt))) concat( code, @@ -897,14 +897,14 @@ function p_dynamics_coord_exa!(p, p_ocp, x, i, t, e) j1 = __symgen(:j) j2 = :($j1 + 1) j12 = :($j1 + 0.5) - ej1 = subs2(e, xt, p.x, j1, p.dim_x) - ej1 = subs2(ej1, ut, p.u, j1, p.dim_u) + ej1 = subs2(e, xt, p.x, j1) + ej1 = subs2(ej1, ut, p.u, j1) ej1 = subs(ej1, p.t, :($(p.t0) + $j1 * $(p.dt))) - ej2 = subs2(e, xt, p.x, j2, p.dim_x) - ej2 = subs2(ej2, ut, p.u, j2, p.dim_u) + ej2 = subs2(e, xt, p.x, j2) + ej2 = subs2(ej2, ut, p.u, j2) ej2 = subs(ej2, p.t, :($(p.t0) + $j2 * $(p.dt))) ej12 = subs5(e, xt, p.x, j1) - ej12 = subs2(ej12, ut, p.u, j1, p.dim_u) + ej12 = subs2(ej12, ut, p.u, j1) ej12 = subs(ej12, p.t, :($(p.t0) + $j12 * $(p.dt))) dxij = :($(p.x)[$i, $j2] - $(p.x)[$i, $j1]) code = quote @@ -967,11 +967,11 @@ function p_lagrange_exa!(p, p_ocp, e, type) j1 = __symgen(:j) j2 = :($j1 + 1) j12 = :($j1 + 0.5) - ej1 = subs2(e, xt, p.x, j1, p.dim_x) - ej1 = subs2(ej1, ut, p.u, j1, p.dim_u) + ej1 = subs2(e, xt, p.x, j1) + ej1 = subs2(ej1, ut, p.u, j1) ej1 = subs(ej1, p.t, :($(p.t0) + $j1 * $(p.dt))) ej12 = subs5(e, xt, p.x, j1) - ej12 = subs2(ej12, ut, p.u, j1, p.dim_u) + ej12 = subs2(ej12, ut, p.u, j1) ej12 = subs(ej12, p.t, :($(p.t0) + $j12 * $(p.dt))) code = quote if scheme == :euler @@ -1030,8 +1030,8 @@ function p_mayer_exa!(p, p_ocp, e, type) xf = __symgen(:xf) e = replace_call(e, p.x, p.t0, x0) e = replace_call(e, p.x, p.tf, xf) - e = subs2(e, x0, p.x, 0, p.dim_x) - e = subs2(e, xf, p.x, :grid_size, p.dim_x) + e = subs2(e, x0, p.x, 0) + e = subs2(e, xf, p.x, :grid_size) # now, x[i](t0) has been replaced by x[i, 0] and x[i](tf) by x[i, grid_size] code = :($pref.objective($p_ocp, $e)) return __wrap(code, p.lnum, p.line) diff --git a/src/utils.jl b/src/utils.jl index ade2f8d..15ea36a 100644 --- a/src/utils.jl +++ b/src/utils.jl @@ -98,43 +98,40 @@ end $(TYPEDSIGNATURES) Substitute occurrences of symbol `x` in expression `e` with indexed access to `y` at time index `j`. -Handles three patterns: +Handles two patterns: - `x[i]` (scalar index) β†’ `y[i, j]` - `x[1:3]` (range index) β†’ `[y[k, j] for k ∈ 1:3]` -- `x` (bare symbol) β†’ `[y[k, j] for k ∈ 1:dim]` -The `dim` parameter specifies the dimension for bare symbol expansion.

Bare symbols and ranges - costs (11 tests): - Lagrange costs with sum(x(t)), sum(x[1:2](t)), sum(u(t)) - Mayer costs at t0 and tf with bare symbols and ranges - Bolza costs combining both Mayer and Lagrange terms 2. Bare symbols and ranges - constraints (13 tests): - Initial constraints: sum(x(0)), x[1:2](0) - Final constraints: sum(x(tf)), x[2:3](tf) - Boundary constraints combining t0 and tf - Path constraints for state, control, and mixed - All constraint types with bare symbols and ranges 3. Bare symbols and ranges - dynamics (6 tests): - Dynamics using sum(x(t)), sum(x[2:3](t)) - Dynamics using sum(u(t)), sum(u[1:2](t)) - Mixed dynamics expressions 4. User-defined functions with ranges (10 tests): - Custom functions: f(x,u), g(x), h(u) - Applied in costs (Lagrange, Mayer, Bolza) - Applied in constraints (initial, final, path, mixed) - Applied in dynamics All tests run across all 4 schemes (euler, midpoint, trapeze, euler_implicit) and verify successful ExaModel creation. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- test/test_onepass_exa.jl | 532 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 532 insertions(+) diff --git a/test/test_onepass_exa.jl b/test/test_onepass_exa.jl index 19c9e4f..2f521ff 100644 --- a/test/test_onepass_exa.jl +++ b/test/test_onepass_exa.jl @@ -104,6 +104,538 @@ function __test_onepass_exa( @test CTParser.as_range(:(x + 1)) == [:(x + 1)] end + test_name = "bare symbols and ranges - costs ($backend_name, $scheme)" + @testset "$test_name" begin + println(test_name) + + # Test: Lagrange with sum over all state components + o = @def begin + t ∈ [0, 1], time + x ∈ RΒ³, state + u ∈ RΒ², control + βˆ‚(x₁)(t) == u₁(t) + βˆ‚(xβ‚‚)(t) == uβ‚‚(t) + βˆ‚(x₃)(t) == u₁(t) + uβ‚‚(t) + x(0) == [1, 2, 3] + x(1) == [4, 5, 6] + ∫(sum(x(t))^2) β†’ min + end + m = discretise_exa(o;

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit includes several related improvements to the substitution functions and their usage in the exa backend: 1. Fixed critical bug in onepass.jl (lines 704, 1053): - Changed :grid_size (quoted symbol) to grid_size (unquoted variable) - This fixes MethodError when using bare symbols in Mayer costs and boundary constraints - Error was: "MethodError: no method matching -(::Symbol, ::Int64)" 2. Renamed subs5 β†’ subs2m throughout codebase: - src/utils.jl: Function rename with updated docstring - src/onepass.jl: 2 call sites updated - test/test_utils.jl: Testset and 8 test calls updated - test/test_utils_bis.jl: Testset name and 1 test updated - test/runtests.jl: Import statement updated - Name now reflects it's the midpoint variant of subs2 3. Enhanced subs2m (formerly subs5): - Added k kwarg: function subs2m(e, x, y, j; k = __symgen(:k)) - Updated docstring to document both scalar and range indexing - Added example showing range substitution: x0[1:3] - Clarified that bare symbols are NOT substituted 4. Added comprehensive tests for subs2m in test/test_utils.jl: - 6 tests for range indexing (basic, step, arithmetic, multiple ranges, symbolic j, single-element) - 2 tests for backward compatibility (scalar indexing, bare symbols) - Total: 8 tests verifying all functionality 5. Added bare symbol handling after subs2m calls in onepass.jl: - Line 918 (p_dynamics_coord_exa!): Added subs for xt in midpoint dynamics - Line 990 (p_lagrange_exa!): Added subs for xt in midpoint Lagrange cost - Pattern: subs(ej12, xt, :([((x[k, j1] + x[k, j1 + 1]) / 2) for k ∈ 1:dim_x])) - Ensures bare symbols like x(t) expand correctly in midpoint scheme 6. Removed unused subs4 function: - Deleted function and docstring from src/utils.jl - Removed testset from test/test_utils.jl - Removed test from test/test_utils_bis.jl - Updated import in test/runtests.jl Files changed: - src/onepass.jl: 2 grid_size fixes, 2 subs5β†’subs2m renames, 2 bare symbol subs additions - src/utils.jl: subs2m rename/enhancement, subs4 removal, cross-reference updates - test/test_utils.jl: subs2m testset with 8 tests, subs4 testset removal - test/test_utils_bis.jl: Testset name update, subs4 test removal - test/runtests.jl: Import statement cleanup πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/onepass.jl | 10 ++++--- src/utils.jl | 51 +++++++++++--------------------- test/runtests.jl | 3 +- test/test_utils.jl | 67 ++++++++++++++++++++++++++++++------------ test/test_utils_bis.jl | 7 ++--- 5 files changed, 76 insertions(+), 62 deletions(-) diff --git a/src/onepass.jl b/src/onepass.jl index 5ef0327..57e3b17 100644 --- a/src/onepass.jl +++ b/src/onepass.jl @@ -701,7 +701,7 @@ function p_constraint_exa!(p, p_ocp, e1, e2, e3, c_type, label) e2 = subs2(e2, x0, p.x, 0) e2 = subs(e2, x0, :([$(p.x)[$k, 0] for $k ∈ 1:$(p.dim_x)])) e2 = subs2(e2, xf, p.x, :grid_size) - e2 = subs(e2, xf, :([$(p.x)[$k, :grid_size] for $k ∈ 1:$(p.dim_x)])) + e2 = subs(e2, xf, :([$(p.x)[$k, grid_size] for $k ∈ 1:$(p.dim_x)])) concat(code, :($pref.constraint($p_ocp, $e2; lcon=($e1), ucon=($e3)))) # debug: to vectorise end (:initial, rg) => begin @@ -914,7 +914,8 @@ function p_dynamics_coord_exa!(p, p_ocp, x, i, t, e) ej2 = subs2(ej2, ut, p.u, j2) ej2 = subs(ej2, ut, :([$(p.u)[$k, $j2] for $k ∈ 1:$(p.dim_u)])) ej2 = subs(ej2, p.t, :($(p.t0) + $j2 * $(p.dt))) - ej12 = subs5(e, xt, p.x, j1) + ej12 = subs2m(e, xt, p.x, j1) + ej12 = subs(ej12, xt, :([(($(p.x)[$k, $j1] + $(p.x)[$k, $j1 + 1]) / 2) for $k ∈ 1:$(p.dim_x)])) ej12 = subs2(ej12, ut, p.u, j1) ej12 = subs(ej12, ut, :([$(p.u)[$k, $j1] for $k ∈ 1:$(p.dim_u)])) ej12 = subs(ej12, p.t, :($(p.t0) + $j12 * $(p.dt))) @@ -985,7 +986,8 @@ function p_lagrange_exa!(p, p_ocp, e, type) ej1 = subs2(ej1, ut, p.u, j1) ej1 = subs(ej1, ut, :([$(p.u)[$k, $j1] for $k ∈ 1:$(p.dim_u)])) ej1 = subs(ej1, p.t, :($(p.t0) + $j1 * $(p.dt))) - ej12 = subs5(e, xt, p.x, j1) + ej12 = subs2m(e, xt, p.x, j1) + ej12 = subs(ej12, xt, :([(($(p.x)[$k, $j1] + $(p.x)[$k, $j1 + 1]) / 2) for $k ∈ 1:$(p.dim_x)])) ej12 = subs2(ej12, ut, p.u, j1) ej12 = subs(ej12, ut, :([$(p.u)[$k, $j1] for $k ∈ 1:$(p.dim_u)])) ej12 = subs(ej12, p.t, :($(p.t0) + $j12 * $(p.dt))) @@ -1050,7 +1052,7 @@ function p_mayer_exa!(p, p_ocp, e, type) e = subs2(e, x0, p.x, 0) e = subs(e, x0, :([$(p.x)[$k, 0] for $k ∈ 1:$(p.dim_x)])) e = subs2(e, xf, p.x, :grid_size) - e = subs(e, xf, :([$(p.x)[$k, :grid_size] for $k ∈ 1:$(p.dim_x)])) + e = subs(e, xf, :([$(p.x)[$k, grid_size] for $k ∈ 1:$(p.dim_x)])) # now, x[i](t0) has been replaced by x[i, 0] and x[i](tf) by x[i, grid_size] code = :($pref.objective($p_ocp, $e)) return __wrap(code, p.lnum, p.line) diff --git a/src/utils.jl b/src/utils.jl index 15ea36a..04a7d2c 100644 --- a/src/utils.jl +++ b/src/utils.jl @@ -102,7 +102,7 @@ Handles two patterns: - `x[i]` (scalar index) β†’ `y[i, j]` - `x[1:3]` (range index) β†’ `[y[k, j] for k ∈ 1:3]` -See also: subs5. +See also: subs2m. # Examples ```@example @@ -166,59 +166,42 @@ end """ $(TYPEDSIGNATURES) -Substitute x[rg] by y[i], whatever rg, in e.
